It's difficult to tell for certain from the video clip, but it would appear that it did detect the car in front and then 'lost' it (and once you'd touched the brakes the system was deactivated anyway). Either way you need to take this back to the dealer to investigate / address.

The system shouldn't be that different from that fitted to the RAV4 and, while I don't bother with LTA, the ACC works exceedingly well - including in rain and heavy spray where the system can 'see' rather better than I can!

To add ... there is a TSB / recall for the LTA system for the bZ4X (amongst others) - you might want to check whether this applies to your car and whether or not the fix has been applied ...

Yes, my dealer confirmed that they applied fix for that.

Actually, I manually turned ACC off and on at the begining of this video. Car didn't detect front car at all! When I was too close I pressed the brake and ACC disabled itself. I tested this with a bigger size car front me and on the middle lane, but I got same problem and sensor didn't detect the front car. Rav4 has safety sense 2.5 but bZ4X has safety sense 3.0, thus I expect much more better and improved detection. 🙄

Just a thought, are you quite sure you enabled ACC rather than CC?

The behaviour suggests CC which will maintain speed right to the point of emergency braking.

I used the ACC and LTA on several recent long motorway journeys with my bZ4X in really bad weather just like your conditions. For stop-start and cruising I found ACC gave perfect control -slowing down nicely and then starting up again and maintaining a good distance from the car in front. Quite different to your car, so maybe there is a problem. On these journeys a lot of road grime had built up on the front sensor panel (found after completed journey) but nevertheless the system still worked fine.

I can only say what I see ... there's a certain amount of "messing about" and setting up at the beginning of the video, and then:

at 12 seconds in the car is travelling at 62mph with ACC set at 70mph and the road apparently 'clear' ahead - the car should be accelerating towards the set speed
at 13 seconds, the car has reached a speed of 64mph with ACC still set at 70mph but showing detection of a car ahead - the car should be considering matching it's speed to that of the car ahead
at 14 seconds, the car has reached a speed of 65mph with ACC still set at 70mph and still showing detection of a car ahead - the car should be considering matching it's speed to that of the car ahead
at 15 seconds, the situation is that same as at 14 seconds in
at 16 seconds, the car is still at 65mph with ACC set at 70mph but the road ahead is shown as clear so that the car is free to accelerate again
at 17 seconds, the situation is that same as at 16 seconds in, but now / shortly we see the car ahead brake
at 18 seconds, the car is up to 66mph and you have, rather sensibly, decided to "take back control" ...

The video doesn't always show the car in front or the ACC display but I would have expected the system to detect the car in front pretty much throughout the video - and, clearly, it doesn't ...

Looking at what Philip has said, with my ACC engaged the car will slow when the car in front slows and will continue to slow after that car has pulled off the lane even though my lane is clear.

Does it work properly in the dry or is this what it always does?

I must admit I'm not as familiar with its behaviour under braking as I find the car brakes too late and too harshly for my tastes when closing on slowing/stopped traffic at highway+ speeds, so I quickly got in the habit of just jabbing the cancel button if I see cars slowing ahead, so I can let the car coast down well in advance (rather than continue at the same speed and then suddenly brake, which is what the ACC tends to do), and then re-engage it when the traffic speeds up and starts to pull away again.

In very heavy rain, my ACC also "lost" a car and shortly after a message popper up to say the system was in active. I just drove manually until next services. When I stopped later the front was filthy so I think it was the sensors got covered in mucky spray and couldn't cope as once I cleaned them off, it didn't happen again

On Cyker's point, if you do leave 3 bar spacing on ACC it just seems to be an invitation to the following truck to overtake regardless that all lane 1 traffic is travelling at 59.5 mph 😬

Can someone confirm that the black plastic plate centre of the front grill is the radar dielectric panel?

Yes, first I thought same. I checked that before the video and adaptive cruise control was on not speed limiter.

Yes footage is correct. This is how they programmed the acc. Last 5 miles car slowly accelerate. You can test it. You will see after 65 car will slowly accelerate to 70.

I am pretty sure ACC was active 😊 and didn't detect the front car. I was shocked couldn't beleive like you so thats why I recorded video and test it on different lane with a different size car front me. My driver's license is over 20 years old and I actively use ACC for long-distance travel. Maybe this is my cars failure not a common problem. I wanted to inform others just incase, because this is a serous safety bug.

1 hour ago, bZ4X said: Yes, first I thought same. I checked that before the video and adaptive cruise control was on not speed limiter.

No, speed limiter is a different function. Cruise control has 2 modes, adaptive and fixed. I don't know the procedure in the BZ4X, in my Corolla you pressed the CC button to activate ACC or press and hold for 3 seconds IIRC, to engage fixed CC.

In UK, with busy roads, ACC is probably the better mode. On the continent with less busy roads and easy passing in lane 2 using FCC is better.

One other thought, and this may not apply in your case, is the ACC override function.

Closing a slower vehicle, if you indicate you want to pull out this will deactivate ACC and switch to FCC. Once you have moved to lane 2 and stopped indicating the car will revert to ACC.

We have a button to choose functions on steering wheel on bz4x. ACC was activated and speed limit you can see that I increased to 70 mph in the video while ACC was on. I will return tomorrow and will test again today weather is sunny lets see tomorrow.

BZ4X, the same, and the control for ACC and FCC is the same. It is possible to select FCC when you thought you had just selected ACC.

Have a look at your manual and check you have not selected FCC by mistake. FCC is my TLA.

I wasn't sure so I washed the whole front of the car and that seemed to work (or could be a complete read herring and just stopping the car and restarting solved it)

I am %100 ACC was active, you can't confuse them as CC has a different logo. You can make sure ACC was active too just watch video you will only see lane and and horizontal distance lines when ACC active not CC.

Like below one frum user guide:

Hello everyone I tested my bZ4X again on the motorway with 1 hour driving under different conditions. My results:

1) If the bz4x sensors adjust the car's own speed relative to the car in front, you will see a car logo like the one below.

2) if road is clear or cannot detect car front, then car logo dissappears! Please see below picture:

And somehow bz4x sometimes doesn't detect front car or cant decide 😊 . Maybe spray thrown up by vehicles affects the sensors.

I recorded another video today on the return way. And my main concern is not ACC but emergency break. If acoustic sensors cannot detect the distance between two cars won't be able to perform emergency brake as well . See after 00:17 lost the detection! Again, I had to brake to avoid crushing front car at the end of the video.

As well as the vehicle in front when the system detects it ... and then loses it again ... 😞

There's something not right and you probably need to get the dealer to look at it.

Thats right it might be only my car. Just wanted share with you as this is a serious safety problem. I will send an email with all my videos and experiences. They should check car logs and report to Toyota JP.

3 minutes ago, bZ4X said: See after 00:17 lost the detection!

Wow! That's really odd. They do say that the system may miss a car cutting in in front of you, but, in this case it just lost sight of everything.

Adaptive cruise control supplements conventional cruise control with an active vehicle-to-vehicle distance control feature. Designed for use on freeways and express ways, in vehicle-to-vehicle distance control mode, your car automatically accelerates or decelerates in order to maintain a preset following distance from the vehicle traveling directly ahead of you.

To activate the system, press the "ON/OFF" button at the end of the stalk on the lower end of the right side of the steering wheel. The radar-ready indicator will appear in the Multi Information Display.

Accelerate or decelerate to your intended speed, then press the stalk down to set it. If you want to go faster, push the stalk upward and hold until you've reached the desired speed and then release it. Or, if you want to slow down, push the stalk down and hold as you decelerate, then release it once you've reached the desired speed.

To cancel cruise control, tap the brakes, pull the stalk towards you or turn the system off with the ON/OFF button.

Adaptive Cruise Control was designed to maintain the preset distance between your car and the car driving in the same lane directly ahead of you.

When it’s active, it automatically adjusts for changes in the speed of the vehicle traveling directly ahead of you in order to maintain the vehicle-to-vehicle distance you set.

In the event that you would like to change the preset distance between vehicles, you can do so by using the radar range button located on the lower right side of the steering wheel. Simply press the button repeatedly to cycle through the ranges available. You'll find them displayed on the Multi Information Display. And finally, you can disable the distance holding feature by pushing the cruise control stalk away and holding it until the indicator disappears and the conventional cruise control indicator lights up.

Guide to Adaptive Cruise Control

How this convenience feature works to reduce your stress on long drives

Adaptive cruise control (ACC) is like traditional cruise control, but smarter. ACC systems allow you to set a desired speed until your vehicle encounters slower-moving traffic. Then it will brake to maintain a set distance from the car ahead. Once the traffic starts moving again or if there is no longer a car in the lane ahead, ACC will accelerate to resume the previous set speed. Although ACC systems may take some getting used to, our survey respondents told us they appreciated the stress relief the feature brings.

“I use the feature mostly on the freeway and in stop-and-go traffic. I find it reduces tension and fatigue,” wrote a 2020 Subaru Outback owner. A 2018 Audi Q5 driver agreed. “It is so nice to just set it and let the car worry about the traffic,” they told CR.

The systems use lasers, radar, cameras, or a combination of those. If traffic slows to a stop, most ACC systems will bring the car to a complete stop, then bring it back up to speed when traffic gets going again. Others work only within certain speeds and/or might not start to accelerate automatically.

Adaptive cruise control (ACC): Cruise control that also assists with acceleration and/or braking to maintain a driver-selected gap to the vehicle in front. Some systems can come to a stop and continue while others cannot. If the car comes to a full stop, you may have to press the accelerator or a button on the steering wheel to start moving again.

Not all systems work at low speeds, so drivers who plan to use ACC in slow traffic should check the limitations of any system they plan to buy. These particular systems will often have the words “traffic jam” or “stop and go” in their name.

These features are usually activated using a button on the steering wheel with the image of a car next to a speedometer with an arrow pointing at it. A conventional cruise control system does not automatically keep a set distance away from the car in front, and it is indicated by a similar logo without the car next to the speedometer. A tip to know if your car has adaptive cruise control or regular cruise control is to look for the “gap distance” button, which usually shows a symbol of a car with horizontal distance bars in front. This button will determine how much space your car leaves between its front bumper and the rear of the car it is following.

In our most recent survey, we asked CR members to rate their experiences with the advanced safety and driver assistance systems on their model-year 2017 to 2022 cars. Respondents answered questions about their satisfaction with the systems. The survey covered about 47,000 vehicles. Most respondents told us they were “very satisfied” with ACC. Satisfaction was higher for older drivers.

OVERALL SATISFACTION

What to Look For in an Adaptive Cruise Control System

Every ACC system works slightly differently, says Kelly Funkhouser, manager for vehicle technology at CR. Some do a better job than others at recognizing merging traffic and automatically apply the brakes, while others wait too long to slow your car, requiring the driver to take control—especially when a vehicle in front of you cuts you off with a close merge.

“Most ACC systems can only be set to speeds above 20 mph but will slow the vehicle to speeds below that in stop-and-go traffic,” she says. “There are a few systems out there that don’t bring the car all the way to a stop but instead just shut off at low speeds. That can be dangerous when you’re traveling behind another slowing vehicle.” She recommends reading the automaker’s website closely and learning about the speed ranges before using ACC while on your test drive.

ACC is meant for convenience, not as a replacement for an alert driver, Funkhouser says. So don’t use adaptive cruise control as an excuse to get distracted. “Just because the car is controlling your speed doesn’t mean that you can check out,” she says. “These systems do not do well at detecting or slowing for vehicles ahead if you approach them at a high rate of speed. The driver should always be monitoring the surrounding traffic and looking ahead for potential hazards.”

However, as with any technological marvel, ACC is not without its set of challenges. This comprehensive guide aims to delve deep into the world of ACC problems, offering solutions that empower drivers to harness the full potential of this groundbreaking system.

Definition and Brief Explanation of Adaptive Cruise Control (ACC)

Adaptive Cruise Control, often referred to as ACC, is a sophisticated driver assistance system that has become increasingly prevalent in modern vehicles. Unlike traditional cruise control, which maintains a constant speed set by the driver, ACC is designed to automatically adjust a vehicle’s speed to maintain a safe following distance from the car ahead. It accomplishes this through a combination of sensors, cameras, and radar technology, which continually monitor the road and vehicles in the vicinity.

The Growing Popularity of ACC in Modern Vehicles

In recent years, ACC has experienced a surge in popularity, rapidly becoming a sought-after feature in new vehicles. The allure of ACC lies in its ability to enhance the driving experience in several ways.

How Adaptive Cruise Control Works

Explanation of How ACC Operates

Adaptive Cruise Control (ACC) is a technological marvel that has revolutionized the way we drive. At its core, ACC functions by using a combination of advanced sensors and cutting-edge technology to make driving safer and more convenient. Here’s a breakdown of how it operates:

Sensors and Technology

ACC systems typically employ a combination of radar, cameras, and in some cases, LIDAR (Light Detection and Ranging) to monitor the road and the vehicles around you. These sensors work in tandem to continuously scan and assess the traffic conditions in real time.

When you engage ACC, the system first establishes a set speed based on your input. As you drive, the radar sensor constantly measures the distance between your vehicle and the one in front. The camera system, often located behind the rearview mirror, assists in identifying the vehicle’s position and speed. ACC then uses this data to maintain a safe following distance by adjusting your vehicle’s speed, either by accelerating or braking.

Benefits of ACC

ACC offers a multitude of benefits to drivers, making it a sought-after feature in modern vehicles:

Reducing Driver Fatigue

Long drives and heavy traffic can be mentally exhausting. ACC steps in as a vigilant co-pilot, taking over the repetitive task of maintaining a safe following distance. This not only reduces the physical and mental strain on the driver but also minimizes the chances of rear-end collisions, which are common in stop-and-go traffic.

Improving Fuel Efficiency

ACC is not just about safety and convenience; it can also contribute to fuel savings. By maintaining a steady, optimal speed and reducing sudden accelerations and decelerations, ACC can help improve fuel efficiency, making it an eco-friendly choice for environmentally conscious drivers.

Introduction to the Components of ACC Systems

To better understand ACC, it’s essential to familiarize yourself with its key components:

Radar Sensors

The radar sensor is the heart of the ACC system. Typically located in the front grille or bumper of your vehicle, it sends out radio waves and measures the time it takes for them to bounce back from nearby vehicles. This information is used to determine the distance and relative speed of the vehicles in front.

Camera Systems

The forward-facing camera, usually situated behind the windshield near the rearview mirror, captures images of the road ahead. These images are processed to identify and track vehicles, lane markings, and road signs.

Control Unit

The control unit acts as the brain of the ACC system. It receives data from the radar and camera sensors, processes it, and sends signals to the vehicle’s throttle and brakes to maintain the desired following distance.

Common Adaptive Cruise Control Problems

Adaptive Cruise Control (ACC) is a remarkable driving aid, but like any technology, it’s not without its share of common issues that drivers may encounter. In this section, we’ll delve into these problems, sharing real-life scenarios, and providing valuable insights into how to address them.

Detailed Overview of Common ACC Issues

Unresponsive ACC

One of the most frequent problems encountered is when the ACC system appears unresponsive. Drivers might engage the system, but it doesn’t adjust speed or maintain the selected following distance as expected.

Unexpected Braking

Some drivers report that their ACC systems apply brakes abruptly, causing discomfort and concern. This can be particularly unsettling, especially on highways.

Erratic Speed Control

In certain situations, ACC might not smoothly adjust the vehicle’s speed, leading to jerky accelerations or decelerations.

Sensor and Camera Blockage

ACC heavily relies on sensors and cameras, and blockages caused by dirt, ice, mud, or debris can impair its functionality.

Real-Life Examples and Scenarios

Let’s consider some real-life scenarios where ACC problems may occur:

Heavy Rain or Snow

Inclement weather, such as heavy rain or snow, can obstruct sensors and reduce their effectiveness. Raindrops or snowflakes on the sensors can create false readings.

Off-Roading

ACC is designed for use on well-marked roads. It may not function optimally on rough or off-road terrain, where sensors can become misaligned or obstructed.

Parked Cars and Roadside Objects

ACC may misinterpret parked vehicles or stationary objects near the road as obstacles, causing unexpected braking.

Sensor Blockage

Explanation of How Radar and Camera Sensors Can Be Obstructed

The radar sensor, often located in the front grille or bumper, and the camera behind the windshield, are essential for ACC’s operation. These sensors can be obstructed by various elements:

Dirt and Dust

Over time, dirt and dust can accumulate on the sensors, reducing their ability to accurately detect vehicles and road markings.

Ice and Snow

In cold weather, ice and snow can cover sensors, leading to distorted readings and decreased performance.

Mud and Water

When driving on muddy or wet roads, sensors can become covered in mud or water, hampering their function.

Impact on ACC Performance During Inclement Weather and Off-Road Conditions

When sensors are obstructed, ACC may misinterpret the road environment, leading to erratic speed control or even temporary deactivation. This can be particularly problematic during poor weather conditions or off-road adventures.

Tips on Maintaining Clean Sensors for Optimal ACC Functionality

To ensure your ACC functions at its best, it’s essential to keep the sensors clean and free from obstruction. Regularly clean the front grille, bumper, and windshield to maintain clear sensor visibility. Use a soft cloth or sponge to remove dirt and debris from the sensors, and avoid using abrasive materials that could damage them.

Calibration Issues

The Importance of Accurate Sensor Calibration for ACC

Sensor calibration is critical for the proper functioning of ACC. Accurate alignment ensures that the system can make precise speed adjustments and maintain the correct following distance.

Causes and Signs of Sensor Misalignment

Sensor misalignment can occur due to various reasons, including minor accidents or even changes in vehicle load. Signs of misalignment may include the ACC system not responding as expected, frequent system errors, or erratic speed control.

How to Address Calibration Issues Through Professional Assistance

If you suspect sensor misalignment or calibration issues, it’s advisable to seek professional assistance. Certified technicians have the tools and expertise to recalibrate the sensors accurately, ensuring that your ACC system operates as intended. Regular calibration checks during routine maintenance can also prevent calibration problems.

Diagnosing and Troubleshooting ACC Problems

Adaptive Cruise Control (ACC) can occasionally encounter issues that may leave drivers wondering how to resolve them. In this section, we’ll provide a step-by-step guide for drivers to diagnose and troubleshoot ACC problems, empowering you to address these issues effectively.

Step-by-Step Guide for Drivers to Diagnose and Troubleshoot ACC Issues

Check ACC Activation: Ensure that you’ve activated ACC correctly. Refer to your vehicle’s owner’s manual to verify the proper procedure.
Sensor Inspection: Examine the front grille, bumper, and windshield for any obstructions or dirt that may be blocking the radar and camera sensors.
Safety Settings: Review your ACC safety settings and ensure they are correctly configured. Some ACC systems allow you to adjust the following distance, speed limits, or other safety parameters.
Vehicle Speed: Ensure your vehicle is traveling at a speed suitable for ACC engagement. In some cases, ACC systems require a minimum speed before they can activate.
Environmental Conditions: Take note of the driving conditions. ACC may not work optimally in heavy rain, snow, or on off-road terrain. If the conditions are unfavorable, it’s best to disengage ACC temporarily.

How to Identify the Root Cause of Problems

Error Messages

Pay attention to any error messages or warnings displayed on your instrument cluster. These messages can provide valuable clues about the nature of the issue.

Observed Behavior

Make a note of how the ACC behaves when encountering problems. Does it fail to engage, disengage unexpectedly, or exhibit erratic speed control? Documenting the specific issue can help in troubleshooting.

Frequency and Patterns

Observe if the problem occurs consistently or sporadically. Note if there are specific patterns, such as it happening only during certain weather conditions or on certain roads.

Recent Changes

Reflect on any recent changes to your vehicle, like alterations or additions, as they may affect ACC functionality.

Recommendations for DIY Solutions and When to Seek Professional Help

Self-diagnosis and maintenance, how to perform basic checks on your acc system.

As a driver, you can take proactive steps to maintain ACC functionality:

Future Trends and Solutions

As technology continues to advance at a rapid pace, the future of Adaptive Cruise Control (ACC) holds exciting promise. In this section, we explore emerging technologies and innovations that are on the horizon, along with their potential to address common ACC problems.

An Overview of Emerging Technologies and Advancements in ACC

Improved Sensor Technology

Future ACC systems are likely to benefit from more advanced sensor technologies. These sensors will offer greater accuracy in detecting and tracking vehicles, even in adverse weather conditions.

Enhanced Connectivity

The integration of ACC with vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication systems will enable cars to share data, providing a more comprehensive view of the road environment. This connectivity will enhance safety and reduce ACC problems caused by unexpected braking or sudden lane changes.

Predictive Algorithms

ACC systems will employ predictive algorithms that can anticipate traffic conditions based on real-time data, such as traffic reports and weather forecasts. This anticipatory capability will help ACC adjust more smoothly to changing traffic patterns.

How These Innovations May Address Common ACC Problems

Advanced sensors will have a higher resistance to environmental factors, reducing the likelihood of sensor blockage. They will be better equipped to differentiate between genuine obstacles and false positives, leading to more accurate and reliable ACC performance.

V2V and V2I communication will enable ACC systems to receive information about traffic conditions and upcoming road changes, allowing for smoother speed adjustments and reduced instances of unexpected braking.

ACC systems of the future will not merely react to the vehicle directly ahead. Instead, they will take into account the behavior of multiple vehicles in the vicinity and make adjustments accordingly. This will mitigate issues related to erratic speed control and improve traffic flow.

The Role of Artificial Intelligence and Machine Learning

Artificial intelligence (AI) and machine learning (ML) will play a pivotal role in shaping the future of ACC. These technologies will enable ACC systems to adapt and learn from their experiences on the road. Here’s how:

Dynamic Adaptability

AI and ML algorithms will allow ACC systems to adapt to different driving styles and traffic conditions more effectively. They will continuously learn and fine-tune their responses.

Collision Avoidance

AI-driven ACC will be capable of not only maintaining safe distances but also predicting and avoiding potential collisions more accurately.

Data Analysis

AI will help in analyzing vast amounts of data generated by ACC sensors, making sense of complex traffic situations and assisting in making real-time decisions.

Adaptive cruise control deceleration problem

Add to quote

I can’t say exactly when this started happening, but when using adaptive cruise control, the engine revs up really high when it’s slowing the car down, like it’s downshifting to decelerate instead of using brakes. This doesn’t seem like it’s good for the engine, and I don’t remember it doing this when I first got the car. Anyone else notice this?

The only time this has happened to me was when I was going downhill. It kind of surprised me since the RPM went up and my first thought was, there goes my mileage. Other times, it either lets off the gas or applies the brakes. It doesn't apply the brakes too hard so you never know which is happening but the vehicle slows down without downshifting when on level and slight downhill ground. Disregard, I just realized that you posted in the hybrid section. I would imagine though, the electric motors should be working to slow you down and recharge the battery rather than using the ICE compression.

This is not the behavior I see when using cruise control. It will brake when the car in front of me slows down (and even come to a stop), but I don’t recall the engine ever revving up unless maybe I’m going down a long steep hill and the hybrid battery is full. If it’s easily repeatable I would try taking a video or maybe try to have your dealership recreate the issue. Is it every time or just occasionally?

Great question. It's not every time, and it seems to happen mostly at highway speeds. If I'm using it on a normal street, it does definitely brake to come to a stop if there's a car in front of me that stops. But when I'm on the highway, if I get close to a car, or a car pulls in front of me, it seems to always use the engine to slow down instead of the brakes. It also does this going downhill, as JFox562 mentioned earlier. So, I don't tend to use it when driving in the mountains.

Are you in D or one of the S modes? The latter are meant to do more or less what you describe, even without cruise control.

Battery temp (high / low), charge state too high to absorb the regen, or to much regen load (higher speeds and/or big descent) the computer will bring in the engine to add drag. It's probably one or more of those factors. It's incrementally harder on the engine than idle, but it's not burning gas in this state and the computer is not going to harm your car. All modern cars cut fuel / spark to the engine and adjust valves to conserve fuel in negative load scenarios. The wear is infinitesimal in the long run and probably cheaper than the alternative (wearing the brakes). Trust the car to do its thing. I live in a hilly area, does it all the time in both the Prius and Rav.

Do you live in a hilly area? I encountered this behavior in the Blackhills of South Dakota when on cruise control. My battery level was maxed out and so the car did some engine braking to bleed off some speed while descending a large hill.

How to use Adaptive Cruise Control on Toyota Avalon

The Avalon’s Dynamic Radar Cruise Control is designed for use when driving on freeways or expressways. This guide shows you how to operate it.

ACC is designed as a comfort system. The strength of the acceleration and the braking intervention are deliberately limited. The driver must therefore remain attentive in all situations despite the support from ACC!

To activate the system, press the on/off button on the end of the stalk on the lower-right side of the steering wheel. The cruise or radar ready indicator will appear in the multi-information display.
Accelerate or decelerate to your intended speed and press the stalk down to set it.
Once set, if you’d like to go faster, move the stalk upward and hold it until you reach the desired speed, then release it.
If you’d like to slow down, push the stalk down and hold it until you reach the desired speed. Once again, release it.
To cancel cruise control, either pull the stalk toward you, tap the brakes, or turn the system off with the on/off button.
Dynamic Radar Cruise Control is designed to maintain the preset distance between your vehicle and the vehicle in the same lane ahead. When active, you can change that distance using the radar range button. It’s on the right side of the steering wheel. Press the button repeatedly to cycle through the three distances available. They’re displayed on the multi-information display.
You can disable the distance-holding feature by pushing the cruise control stalk away and holding it until the indicator disappears and the conventional cruise control indicator lights up.
The vehicle-to-vehicle distance control feature cancels automatically when the actual vehicle speed falls below 25 miles an hour.
The preset memory is retained until the speed drops below 10 miles an hour, then it’s cleared, the vehicle stability control steps in to help control lateral loss of traction, the radar sensor behind the grille is covered or blocked, or the brake is applied.

2021 Venza adaptive cruise control

Add to quote

I’ve got a 2021 Venza limited trim. Previously drove a Subaru Outback. Comparing the adaptive cruise control on both: Toyota loses the vehicle in front more easily than Subaru, a Toyota brakes normally when closing in on a stopped vehicle; Subaru waits so long you can’t stand the suspense Both vehicles brake unnecessarily when the lead vehicle turns off on a side road Toyota system often shuts off without telling you - you have to watch the monitor carefully. Subaru turns off less often and always warns you Bh and large, Toyota has a lot of work to do with their system before if inspires confidence

Considering purchasing a new 2021 Venza. Anyone have pros and cons besides the OP above? Thanks

The Venza limited has most of the bells and whistles. Lower trim levels have to be carefully examined to see if they have what you want. Also look at the test sites and check on headlights. My feeling is the car is pretty good, comfortable, and a pleasure to drive, apart from its Nav system that is hopeless compared to google maps, and its Safety Sense 2.0 that is only so-so and has you watching while you drive to be sure it’s actually “on” because it checks out unexpectedly often. Leaves you uncomfortable. Many reviews complain about the tap-tap-tap controls for volume, temp, and fan speed. I didn’t find that a problem. Consumer Reports complains about noise levels— I find them no worse than my old 2015 3.6 liter Subaru Outback. Tromping on the gas you hear the engine, but on the Outback you do too. Consumer Reports also seems to like fake gear shifting on a CVT to imitate a normal transmission, but I find I don’t like that and it is not present on the Venza - whew! It is on there on the Subaru XT, and I hate it. The Venza is big for no reason - it doesn’t have normal cargo space, unusual headroom or leg room. So big for what? Sound system outperforms Subaru. I am surprised to learn how complicated a hybrid vehicle is, and I’m relying upon Toyota experience in this area over a few decades to have no reliability issues. Some routine activities like jump starting and oil changing need new attention. There is a good warranty. Gas mileage is about 35 mpg, which isn’t bad, but not amazing.

no hitch...ended up, again, the wifes fob acting up again...after replacing 2 batteries and 1 fob from dealer ...finally shes getting the hang of it now...

Hey y'all Is there a way to disable the adaptive cruise control feature without having to shut off the cruise control completely? The adaptive seems to over-compensate when trying to get back up to the set speed after a slow down which spikes the RPMs up to 4 or 5k. Both my gas mileage and I are tired of it

#2 Raijin822 Well-Known Member

hold down the cruise control button and you will activate constant speed cruise which is the traditional cruise control function w/o the distance keeping and etc.

Give it some time and you may get used to it. I hated it for a few weeks until I got the hang of it. Otherwise you can turn it off by holding the cruise on button for a few seconds instead of clicking it on like usual.

you can turn the adaptive portion of the cruise off and have standard "regular cruise" but, and this is a BIG BUT, you will still have the over shifting issues, and huge rpm swings, for what appear as no reason. the cruise is too sensitive to mph loss, and the 6 speed transmission with the 2 overdrive gears just constantly hunts to be "in the correct gear", for the power requested by the throttle position. some think the tunes are the answer but, again... it is the too sensitive cruise that is the major factor here. tunes will help but, will not eliminate over sensitive shifting. this is the only thing that drives me nuts, about this truck, platform. yes, I have a KDmax tune in mine.

The following distance adjustment also appears to have impact when it resumes the set speed. Shorter following distance seems to have a more aggressive acceleration when resuming your set speed. I also have a Subaru with their Eyesight system. They have a setting where you can adjust the level of acceleration from sleepy to scary.

I'm lazy so I use cruise almost all the time. It does use more fuel though. 1 other dislike is on a sharp turn when the cruise sees another car and brakes hard. But like I said I still use cruise.

Pre-collision/Adaptive cruise control stops working

Add to quote
I would say almost 30-35 % of the time when I am driving, I see Pre-collision getting disabled with warning "Pre-collision disabled, please clean sensors"
I have checked multiple times and the sensors are very clean.
The warning light comes up irrespective of the fact if I am using adaptive cruise control or not.
Most of the time when I power off the car and power it back on, it starts to work again.
When I am using adaptive cruise control, it stops detecting the car in front and accelerates irrespective of the distance between my car and the car in front and I have to break or else it will end up in a crash.
Once the car stops maintaining the distance from the Front car, the pre-collision warning light comes up in 10-20 mins. However, during those 10-20 mins, CHR does not maintain the distance with the car in front of me.

Just a thought...are you living in a cold climate? This error happened to me yesterday while driving in snow. I cleared off the Toyota badge (it had a thin coat of ice). Later in the day, I started the vehicle and the error was still there... Checked the badge and it was clear. Restarted the car 2-3 times. Error was still there but eventually just went away. I had gone thru an automated car wash the day before in freezing temps. I'm suspecting that ice had formed under the hood and in front of the radar?

I live in the Netherlands and the weather is usually moderate here.

Yeah. Sorry I am out of ideas. Good luck...

APuri said: I have Toyota CHR for the past one year, however since last 6 months very often Pre-collision system stops working. I would say almost 30-35 % of the time when I am driving, I see Pre-collision getting disabled with warning "Pre-collision disabled, please clean sensors" I have checked multiple times and the sensors are very clean. The warning light comes up irrespective of the fact if I am using adaptive cruise control or not. Most of the time when I power off the car and power it back on, it starts to work again. When I am using adaptive cruise control, it stops detecting the car in front and accelerates irrespective of the distance between my car and the car in front and I have to break or else it will end up in a crash. Once the car stops maintaining the distance from the Front car, the pre-collision warning light comes up in 10-20 mins. However, during those 10-20 mins, CHR does not maintain the distance with the car in front of me. Here is an image yellow pre-collision disable light that pops up after it malfunctions. The error message usually says something like “Pre-collision warning system is unavailable, please clean the sensors”, whereas sensors are clean and shiny. View attachment 6205 I have already taken this car to dealer about 4 times, however they are unable to find anything. Anyone who has cone across similar issue or any suggestions are welcome?

I should add mine is a RAV4 2020

In case someone is still wondering, the issue is about the front camera radar. If it suddenly works again you should be worried. That is the sign that it is about to fail. It cost 1800€ to replace and its not just me who have the issue. Its also not included inthe warranty.

Hello, I am having the same problem with my toyota CHR hybrid 2018.

Radar Controlled Cruise Control question

Discussion in ' 5th Gen 4Runners (2010-2024) ' started by GenoBluzGtr , Jan 21, 2022 .

#1 GenoBluzGtr [OP] New Member

This is my first vehicle with RCCC. I noticed on a trip over the past two days that if someone merges in front of me or if I'm in a turn and a car is slightly ahead of in the adjacent lane, that the system executes a pretty aggressive slow-down on the 4Runner. My question is, when this happens, do my brake lights come on? The reason I ask is that the action is very much like me hitting the brakes pretty darned hard, and if I was behind me, I would want to see brake lights when that happens. Any one able to confirm if they DO or DON'T activate when this happens? If the do not, I can foresee some issues down the road.

#2 LandCruiser I have Toyotas

If the truck applies the brakes, yes. If it uses engine compression by downshifting no. From what you said, sounds like it applies the brakes. Also, the behavior you’re describing is what happens when a heavy, primitive vehicle is given new technology it was never designed for.

#3 Chucklehead Enjoy the ride! You only get one trip

Something else with this system I wasnt aware of until i got to that part of the manual is the distance the radar reads and adjusts your speed is adjustable—- basically car lengths. The default is what seems like a football field length which is so far it invites people to cut in front of you. to answer your question though- yeah if the vehicle auto brakes the brake lights also auto illuminate…

#4 Spare Parts New Member

We have this on our Rav4 Prime, and I can say it acts the same way, annoys me, but helps keep the speedo in a reasonable place.

#5 universalfrost New Member

yeah i find that it can be too aggressive at times...ive had similar tech in Audi and BMW vehicles that was more "intelligent" and less aggressive unless it really deemed the need to in case of crash at high speeds etc... at the end of the day it is nice to have on the 4runner and definitely appreciate it on long highway drives where i don't always have to tap the brakes or cancel the cruise control constantly ..

#6 Will New Member

I found my 2019 Tacoma would react aggressively.

#7 SCgman New Member

Is there a readers digest version on how to turn this feature off?

#8 matoolie Taking it a day at a time

You can also turn it off and use normal cruise control if you like. Just push and hold the cruise control ON button until message that the radar is turned off shows up on information display.

#9 SCgman New Member

So, depress the button on the stick until I get a dash display?

When the radar cruise slows you down, does it resume speed automatically when the distance to the vehicle in front of you increases? No such newfangledness on my 4R, so I'm just curious...

Yeah hammers it no doubt. Very little tolerance for deviation above or below set speed. So a big part of my daily drive to work is a nearly flat stretch about 30 miles long with no stoplights. 1/2 is 60mph and 1/2 is 55mph. Ive been experiment using cruise and driving manually. I’m finding cruise is about 2mpg worse than driving manually. Anybody else see this with using cruise?

Ditto. I don't think cruise increases gas mileage if your normal manual driving technique isn't weird. In fact, I'm not surprised that it reduces it. I would like to see a controlled test of using Radar Cruise, vs Non-Radar Cruise, vs Manual and see if there's a difference between the 3. One other point... I was driving in Northern NJ the other day during a snowstorm, and got a dash-light and message saying that my collision avoidance system was unable to work due to the "sensor needs cleaning". During this, I also could not engage Cruise control at all. I pulled over and found a layer of snow-slush-salt on my sensor on the grille. Wiped it off and the fault cleared. I wish I had known about holding the button down to use "normal" cruise... to see it it would bypass the fault.

How To Turn Off Adaptive Cruise Control Toyota

When it came to my 2014, I had previously written instructions on how to turn off the dynamic radar speed control. Toyota has altered the method, making it a little bit simpler, as Vet Interested has pointed out. A procedure that took up almost an entire manual page in 2014 is now condensed to a single bullet point in the 2017 version. But the answer is just there, right in front of us. Instead of immediately pressing the stalk’s end button to activate cruise control, you can cancel the radar cruise and switch to conventional cruise by holding the button down for a few seconds. The panel between your speedometer and tachometer will show that alert.

Page 220 of your 2017 Avalon owner’s handbook contains this information. That page contains the attachment you’re about to see.

In This Article...

How do I deactivate the adaptive cruise control?

You can disable Adaptive Cruise Control by doing any of the following:

Step on the brakes.
Select CANCEL from the menu.
Press the ON/OFF button for the cruise control.

Toyota Adaptive Cruise Control: How Does It Work?

The Toyota automobiles’ adaptive cruise control operates by spotting other cars in its lane. Depending on how close you are to other vehicles, it might both speed up and slow down your car. If necessary, it can even automatically apply the brakes.

You must push the On/Off button to turn on the ACC. The stalk must then be turned on by accelerating to the desired speed. Press the stalk and keep it down to set the ACC to that speed; after that, you can let go of it. You can use the On/Off Button once more to turn off the ACC.

How is adaptive cruise activated?

1. Press the cruise control ON/OFF button on the steering wheel to activate the feature. If your car has a Head-Up Display, or a cluster display, you’ll see a white ADAPTIVE CRUISE CONTROL icon when the system is turned on. An arc with a tiny triangle pointing through it or a speedometer with a car on top might be the icon.

2. While moving at the specified speed, press the SET button to select a cruise speed. When the system is in use, the white ADAPTIVE CRUISE CONTROL symbol will turn green.

Is Toyota Safety Sense deactivatable?

The PCS function can be ON or OFF at any time, and the timing of the warning can be changed. However, following ignition, it will switch itself back on. Toyota would like to warn its customers that PCS does not detect pedestrians and that the laser may not function correctly in some circumstances.

Toyota first used adaptive cruise control when?

On the Japanese market Celsior, Toyota featured a “laser adaptive cruise control” (lidar) system. Instead of using the brakes to slow down, it used throttle control and downshifting. In 1999, Mercedes-Benz launched “Distronic,” the company’s first radar-assisted ACC, to the CL-Class and S-Class models.

In stop-and-go traffic, does the Toyota adaptive cruise control function?

When you’re in stop-and-go traffic, it works great, but when you’re approaching a backup at high speed, the car won’t see the stopped automobiles in front of it until the radar is in range. It looks to behave similarly to a distracted driver, in my opinion. I’ll either apply the brakes or hit the cancel button to slow down naturally. Once I’m inside the backup or at least getting close to it, I’ll reactivate the cruise control.

What does Toyota’s dynamic cruise control do?

Control for Dynamic Radar Cruise This sophisticated cruise control adjusts your speed while using radar and a camera on the windshield to assist you keep a predetermined distance from the vehicle in front of you.

Can the Subaru disable the adaptive cruise control?

Adaptive Advanced Cruise Control The Adaptive Cruise Control button is located on the right side of the steering wheel and is used to activate or deactivate adaptive cruise control (see page 12).

What distinguishes adaptive cruise control from cruise control?

Conventional cruise control allows you to select a constant speed. A development of standard cruise control is adaptive cruise control (ACC). With ACC, your car’s speed is automatically adjusted to keep up with the vehicle in front of you. ACC can automatically slow down the vehicle in front of it. Your ACC enables your automobile to return to the speed that you have chosen once the vehicle in front of you pulls out of your lane or accelerates past it. You merely need to turn on the system and choose your chosen following distance after choosing your pace.

How to Use It?

Depending on the type of your car, the precise controls will vary, but typically you must first set a cruising speed and a following distance from the vehicle in front of you.

Controls on the steering wheel are used to operate most systems. The brake and accelerator pedals can also be used at any time to make an intervention.

Using the +/- speed button, you may adjust the speed. Alternatively, you can keep accelerating until you reach the desired speed. The ACC is instructed to “remember the speed” once you push a button. Most ACC systems can operate at speeds as low as 25 MPH.

You can set a following distance, or time interval, between your vehicle and the vehicle in front of you using ACC systems. Car-to-car distance options from ACC systems include short, medium, and long distances. In response to shifting traffic conditions, you can always adjust the setting. The majority of driving situations call for a lengthier setting.

How Does it Work?

As with conventional cruise control systems, ACC maintains your vehicle at the speed you specify as long as nothing is in front of you. To measure the distance between your automobile and the vehicles in front of it, a sensor unit has been fitted.

sensors for distance and speed. Two sensors are used by ACC to gather data: a distance sensor that measures the distance between your car and the car in front of it and a speed sensor that regulates your car’s speed. These sensors provide data that ACC utilizes to alter your speed and maintain the predetermined separation from the vehicle in front of you.

A closer look at radar-based systems Let’s examine one ACC innovation: radar-based ACC. Some ACC systems send out waves of radar that bounce off the things in front of your automobile. The ACC system determines whether the car is inside the prescribed distance based on the radar reflection by using distance, direction, and relative speed. After predicting your car’s route, ACC determines whether any of the vehicles in front of you are closer than the predetermined distance.

How can I fix the momentarily faulty adaptive cruise?

Only for Adaptive Cruise, which is momentarily unavailable: The Multi Axis Sensor Learn will be used to resolve the majority of the cars. Perform the Long Range Radar Learn specified in the Radar Sensor Module – Long Range Programming and Setup process in Service Information if the issue is still present.

On my Atlas, how can I deactivate adaptive cruise control?

regards cars with the adaptive cruise control feature.

Put Adaptive Cruise Control off.

On the left side of the steering wheel, there is a button that you should press.
Scroll to Speed using the vertical menu buttons on the driving wheel.
Press the button after choosing Cruise Control in the instrument cluster display.

Use of brakes by adaptive cruise control

An active safety technology called adaptive cruise control (ACC) automatically regulates a vehicle’s acceleration and braking. It is started by pressing a button on the steering wheel, and it is stopped by the driver braking or by pressing another button.

Even the most ardent vehicle lovers have trips they would prefer to be driven through, or at the very least assisted in a way that would allow them to unwind behind the wheel after a demanding day. Even better if doing so makes their driving experience safer and more exciting while conserving gasoline. Fundamentally, this is the driving force underlying cruise control technology. Even though it has been around for two decades, cruise control use is still increasing and helps drivers at more and more points along the way.

The acceleration and braking of a vehicle are automatically controlled by adaptive cruise control.

What does a problem with adaptive cruise control mean?

The driver assistance system known as adaptive cruise control (ACC) limits the top speed of vehicles and automatically reduces the speed of the automobile when it detects traffic in front of it. Autonomous cruise control is another name for the technology.

Standard cruise control allows the driver to select a constant pace and depress the accelerator, but it needs the driver’s help to turn off when the predetermined speed is no longer feasible. Without the driver’s input, adaptive cruise control enables intelligent, proactive speed management. In circumstances where the driver would have previously needed to intervene, ACC automates replies. The system can lessen driver discomfort and tiredness more than conventional cruise control while keeping a safe distance from vehicles in front of it on the road.

Although some automakers, like Subaru, use a coupled laser and camera setup, the majority of ACC systems are based on a RADAR module in the vehicle’s front bumper. The speed of the traffic in front of the vehicle as compared to the controlled vehicle is measured by these sensor technologies. With + and -, a driver specifies the top speed as well as the reasonable following distance. The system actively locks onto the vehicle in front when a driver hits the set button. Then, ACC keeps the parameters within the predetermined range by slowing down or applying 50% of the maximum braking force. Chimes play when the ACC is about to reach its limits, and the brake or brake now warning lights turn on.

Although ACC is a crucial part of autonomous driving systems, this does not mean that they are capable of autonomous driving. Some systems in the lower price range, which start at around $500, can only function at speeds more than 25 MPH. Full stop-and-go traffic can be handled by more sophisticated arrangements. It is significant to highlight that most adaptive cruise control systems do not have sufficient sensor range or speed to prevent collisions with vehicles moving in the other direction. This means that more sophisticated driver assistance systems in the semi-autonomous to fully driverless range are the only ones that can reduce side-by-side or head-on crashes.

Can cruise control reduce fuel use?

Yes, generally speaking. Due to its capacity to maintain a constant pace, cruise control can help you become more fuel-efficient and can help you save on gas on average by 714%. In contrast, the constant acceleration and deceleration caused by the driver’s foot on the pedals might use up more gas.

Is adaptive cruise control financially worthwhile?

Prior to a few years ago, ACC was normally only available on more expensive higher trim levels unless you were purchasing a luxury vehicle. And to some extent, it is still true. Numerous vehicles are sold with a standard package that is devoid of numerous features, including ACC, additional safety controls, and GPS. But those can be quickly added by upgrading the vehicle’s trim or adding a premium package.

Is adaptive cruise control therefore worthwhile? Absolutely. It’s a game-changer, as we previously stated, especially on longer road journeys. Modern ACC is 100 percent worth the higher cost, unlike outdated cruise control, which was not worth the work it took to activate.

Thankfully, technology has improved to the point that nearly every new car is essentially a large computer, and the majority of new cars come with advanced or adaptive cruise control. Adaptive cruise control, for instance, is currently regarded by Toyota as “standard equipment on all vehicles.

Make sure adaptive cruise control is a feature of your next vehicle if you plan to purchase a new or barely used vehicle anytime soon. Later on, you can thank me.

How does a 2022 Toyota Camry’s cruise control work?

To turn on the cruise control, press the primary switch. An indicator for the cruise control will be shown. To turn off the cruise control, press the switch one more time.

Adaptive cruise control is considered a semi-autonomous feature. It is a system designed to assist vehicles in maintaining a proper following distance behind other cars.

Adaptive cruise control will automatically adjust the vehicles speed. Similar semi-autonomous features include auto emergency brakes which slam on the brakes for you if the system predicts a likely collision.

Furthermore, there is blind-spot monitoring which detects other vehicles in your path when attempting to switch lanes.

Cruise Control Problem Of The 2013 Toyota Tacoma

Brand new vehicle. Cruise control fails to disengage when depressing brake pedal. This is the on-going status. Brake must be pushed down about 2 before cruise control disengages. Despite repeated attempts to get the vehicle serviced, Toyota of olympia refuses to acknowledge the problem and so refuses to fix it even though vehicle in under warranty and extended service agreement. Several instances have occurred and resulted in unintended travel of a couple hundred feet towards an obstacle because the cruise did not disengage. Ive driven scores of vehicles over the last 40 years and none of them had a cruise control that needed the brake pedal to be pushed down so far to disengage. It may be a design flaw that is causing an unsafe driving condition for anyone and everyone who drives a Tacoma, or it is a defective vehicle. Either way it is a danger.

What Are Some Issues With Adaptive Cruise Control

While it is not necessarily specific to pickups, yet a more general issue, there are some concerns with adaptive cruise control.

Firstly, the main concern with this type of cruise control is inattentiveness. This type of cruise control is by no means a true autonomous driving experience, meaning you need to be keeping a close eye on the traffic ahead of you .

However, as humans are humans, when something is doing the driving for us, we tend to be less attentive to the road. This leaves a system that is not meant to truly drive, driving for us.

Secondly, another big concern, is that these systems are relatively new, meaning that they have not been fully tested for years. This means we are testing these systems on public roads, leaving everyone at risk.

Cruise Control Problem Of The 2008 Toyota Tacoma

My Toyota Tacoma will suddenly accelerate from a dead stop. I was stopped at a stop sign and the engine sped up I had both feet on the brakes, back wheels spinning. I put it into neutral and it went back to normal. Another time I was backing into a parking space and it did it again, in reverse! again, neutral stopped it. This has happened 3 times and Im afraid Im going to kill myself or someone else! no, I did not have a foot on the accelerator and the brake! this happens after Ive had the cruise control on, then turned it off. And again, it happens from a dead stop. I have a complaint number from Toyota. The dealer did diagnostics and couldnt find anything wrong. So Toyota will do nothing. I am contacting you to make public what we are experiencing with my Tacoma in case of a horrific accident. Toyota needs to stand behind what they sell. I have always maintained my truck this is not due to my negligence. It is due to Toyotas. I need my truck fixed before someone is hurt or killed by it.

Towing And Payload Capacity

At its brawniest, the Tacoma can tow up to 6800 pounds with rear-wheel drive four-wheel-drive versions can pull 6500 pounds. The Tacomas 1685-pound maximum payload capacity is only available on two-wheel drive models with the four-cylinder engine going with four-wheel drive and the V-6 engine results in much lower capabilities.

After last years significant refresh, there are no changes to the core Tacoma offerings. There are, however, a pair of new limited-edition trims for buyers looking for something a little different. The Trail Special Edition is based on the near entry-level SR5 trim with the double-cab body style. Limited to 7,000 units, it comes with all-terrain tires and lockable bed storage bins. The drivers side bin is even insulated so it can function as a built-in cooler. Theres also a Nightshade Special Edition based on the more expensive Limited trim, but changes are only aesthetic, with blacked-out badging and trim throughout. Just 5,000 are planned for production.

Fuel Economy And Real

The V-6 Tacomas EPA-rated fuel economy ranks in the middle of the pack, but in our real-world highway testing, it falls short of more efficient competitors. Although the manual transmission with the V-6 has the worst fuel economy, its way more fun to drive. In our real-world fuel-economy test, the Tacoma matched its EPA highway estimate of 23 mpg. Still, this was 5 mpg less than the Honda Ridgeline and the diesel GMC Canyon .

What New Features Does The 2018 Toyota Tacoma Offer

The Tacoma is Toyotas highly capable midsize pickup truck, offering excellent performance, off-road prowess, high-level utility and interior comfort and refinement. For the 2018 model-year, the Tacoma received some upgrades, including new safety features and minor grille changes on a several of the trims.

Cruise Control Problem Of The 2009 Toyota Tacoma

Using the cruise control, set at 61mph, climbing a small hill, the truck downshifted at least 3 times, revving the engine to over 5000 rpm. It startled me. My first reaction was to shift to neutral, but I knew that would cause the engine to over rev. I lifted the cruise control to shut it off, and the engine speed dropped. I drove a while with the cruise off, then retried it. On the first hill the same thing happened, and I shut off the cruise. I tried two more times with the same results. When I drove with out the cruise control on, the engine would down shift only one time, then at the top of the hill would upshift, resuming the normal operation. Through out the rest if my visit to PA, I drove w/o cruise control, and there were no over shifting incidents. On the return trip to nc on the 26th, I reset the cruise, and upon climbing a hill, the same thing happened. I shut off the cruise control until I got out of the hills, and then the operation seemed normal. I have made that trip before in the truck, and had nothing like the experience I just mentioned.

Title : Active carbons as nanoporous materials for solving of environmental problems

However, up to now, the main carriers of catalytic additives have been mineral sorbents: silica gels, alumogels. This is obviously due to the fact that they consist of pure homogeneous components SiO2 and Al2O3, respectively. It is generally known that impurities, especially the ash elements, are catalytic poisons that reduce the effectiveness of the catalyst. Therefore, carbon sorbents with 5-15% by weight of ash elements in their composition are not used in the above mentioned technologies. However, in such an important field as a gas-mask technique, carbon sorbents (active carbons) are carriers of catalytic additives, providing effective protection of a person against any types of potent poisonous substances (PPS). In ESPE “JSC "Neorganika" there has been developed the technology of unique ashless spherical carbon carrier-catalysts by the method of liquid forming of furfural copolymers with subsequent gas-vapor activation, brand PAC. Active carbons PAC have 100% qualitative characteristics of the three main properties of carbon sorbents: strength - 100%, the proportion of sorbing pores in the pore space – 100%, purity - 100% (ash content is close to zero). A particularly outstanding feature of active PAC carbons is their uniquely high mechanical compressive strength of 740 ± 40 MPa, which is 3-7 times larger than that of such materials as granite, quartzite, electric coal, and is comparable to the value for cast iron - 400-1000 MPa. This allows the PAC to operate under severe conditions in moving and fluidized beds. Obviously, it is time to actively develop catalysts based on PAC sorbents for oil refining, petrochemicals, gas processing and various technologies of organic synthesis.

Victor M. Mukhin was born in 1946 in the town of Orsk, Russia. In 1970 he graduated the Technological Institute in Leningrad. Victor M. Mukhin was directed to work to the scientific-industrial organization "Neorganika" (Elektrostal, Moscow region) where he is working during 47 years, at present as the head of the laboratory of carbon sorbents. Victor M. Mukhin defended a Ph. D. thesis and a doctoral thesis at the Mendeleev University of Chemical Technology of Russia (in 1979 and 1997 accordingly). Professor of Mendeleev University of Chemical Technology of Russia. Scientific interests: production, investigation and application of active carbons, technological and ecological carbon-adsorptive processes, environmental protection, production of ecologically clean food.
