• NHTSA In Action

Plus, Automatic Emergency Braking & Pedestrian Automatic Emergency Braking

Driver assistance technologies in your car not only help to keep you and your passengers safe, but also other drivers and pedestrians. When shopping for a new or used vehicle, you may notice that different manufacturers use different names for the technologies. NHTSA is helping consumers break through the confusion with explanations about how these technologies work. It’s important to understand that some driver assistance technologies are designed to warn you if you’re at risk of an impending crash, while others are designed to take action to avoid a crash. Be sure to review your vehicle’s owner’s manual for more information on your vehicle’s technology and safety features. Understanding how the technology works and how it can better protect you, your passengers and others is key.

Forward Collision Warning

Detects a potential collision with a vehicle ahead and provides a warning to the driver.

This is a NHTSA recommended safety technology.

Lane Departure Warning

Monitors the vehicle’s position within the driving lane and alerts the driver as the vehicle approaches or crosses lane markers.

Rear Cross Traffic Warning

Warns the driver of a potential collision, while in reverse, that may be outside the view of the backup camera.

Blind Spot Warning

Warns of a vehicle in the driver’s blind spot.

Automatic Emergency Braking

Applies brakes automatically when a forward collision is imminent. There are two types of automatic emergency braking systems that meet NHTSA’s performance specifications: dynamic brake support and crash imminent braking.

These are NHTSA recommended safety technologies.

Pedestrian Automatic Emergency Braking

Detects a pedestrian in front of the vehicle and automatically applies brakes if a collision is imminent.

Rear Automatic Braking

Detects a potential collision while in reverse and automatically applies brakes if a crash is imminent.

Blind Spot Intervention

Applies brakes or provides steering if the driver begins to change to a lane where a vehicle is detected in the blind spot.

Adaptive Cruise Control

Automatically adjusts the vehicle’s speed to keep a pre-set distance from the vehicle in front of it.

Lane Centering Assistance

Provides continual steering to keep the vehicle centered in its lane.

Lane Keeping Assistance

Automatically and gently steers to prevent the vehicle from departing the lane.

Automatic High Beams

Automatically switches the vehicle’s headlights between low and high beams when an oncoming vehicle approaches based on lighting conditions and traffic. This is also known as semi-automatic beam switching.

Backup Camera

Provides the driver with a clear view directly behind the vehicle when in reverse. This is also known as a rearview video system.

Automatic Crash Notification

An automatic crash notification system notifies emergency responders that a crash has occurred and provides its location.

Technologies Explained

A forward collision warning system monitors the vehicle’s speed, the speed of the vehicle in front of it and the distance between the vehicles. If the vehicle gets too close to the vehicle ahead, the system will warn the driver of an impending crash. It’s important to note that forward collision warning systems only provide a warning to the driver and do not take action to avoid a crash.  Watch how it works.

More on how FCW works

Forward collision warning systems use sensors to detect slower-moving or stationary vehicles. When the distance between vehicles becomes so short that a crash is imminent, a signal alerts the driver so that the driver can apply the brakes or take evasive action, such as steering, to prevent a potential crash. Vehicles with this technology provide drivers with an audible alert, a visual display, or other warning signals. This helps prevent frontal crashes into the rear of slower moving or stopped vehicles.

A lane departure warning system monitors lane markings and alerts the driver when it detects that the vehicle is drifting out of its lane. It’s important to note that a lane departure warning system only provides a warning to the driver and does not take action to avoid a crash.

More on how LDW works

A lane departure warning system uses a camera to detect when the vehicle is veering out of its lane. An audio, visual, or other alert warns the driver of the unintentional lane shift so the driver can steer the vehicle back into its lane. This provides a valuable safety benefit and can help keep drivers and passengers safe from crashes such as when a vehicle strikes a car in an adjacent lane, including sideswiping a vehicle traveling in the same direction or hitting a vehicle traveling in the opposite direction. Also, lane departure warning could prevent incidence of road departure and subsequent crashes off roadway.

Rear cross traffic warning alerts the driver of potential collisions, while in reverse, that may be outside the view of the backup camera.

Blind spot warning systems alert drivers with an audio or visual warning if there are vehicles in adjacent lanes that the driver may not see when making a lane change. Watch how it works.

NHTSA recommends dynamic brake support and crash imminent braking systems

Automatic emergency braking systems apply the vehicle’s brakes automatically in time to avoid or mitigate an impending forward crash with another vehicle. NHTSA believes AEB systems represent the next wave of potentially significant advances in vehicle safety. Dynamic brake support and crash imminent braking are AEB systems that potentially save lives and reduce moderate and less severe rear-end crashes that are common on our roadways. Watch how it works.

More on how DBS and CIB systems work

If the system detects a crash and the driver brakes, but not hard enough to avoid the crash, DBS automatically supplements the driver’s braking to avoid a crash. If the system detects a crash but the driver does not brake to at all, CIB automatically applies the vehicle’s brakes to slow or stop the car, avoiding the crash or reducing its severity.

Extensive research on this technology and on relevant performance measures showed that a number of AEB systems currently available in the marketplace are capable of avoiding or reducing the severity of rear-end crashes in certain situations.

A pedestrian automatic emergency braking system uses information from forward sensors to detect a pedestrian in the vehicle’s path. The system will provide automatic braking if the driver has not acted to avoid a crash. Watch how it works.

Rear automatic braking uses sensors, like parking sensors and the backup camera, to detect objects behind the vehicle. If the system detects a potential collision while in reverse, it automatically applies the brakes if a crash is imminent.

Blind spot intervention helps prevent a collision with a vehicle in the driver’s blind spot. If the driver ignores the blind spot warning, and starts to change to a lane where there’s a vehicle, the system activates and automatically applies light braking pressure, or provides steering input to guide the vehicle back into the original lane. The system monitors for vehicles in the driver’s blind spot using rear-facing cameras or proximity sensors.

Adaptive cruise control automatically adjusts the vehicle’s speed to keep a pre-set distance between it and the vehicle in front of it.

Lane centering assistance utilizes a camera-based vision system designed to monitor the vehicle’s lane position and automatically and continuously apply steering inputs needed to keep the vehicle centered within its lane.

Lane keeping assistance helps prevent the vehicle from unintentionally drifting out of its lane. The system uses information provided by lane departure warning sensors to determine whether the vehicle is about to unintentionally move out of its lane of travel. If so, the system activates and corrects the steering, brakes or accelerates one or more of the wheels, or does a combination of both, resulting in the vehicle returning to its intended lane of travel.

Automatic high beams automatically switch the vehicle’s headlights between the lower beam and the higher beam, based on lighting conditions and traffic, when an oncoming vehicle approaches. This technology, also known as semi-automatic beam switching headlamps, uses photometric sensors or onboard cameras to detect when to switch between high and low beams.

A backup camera, also known as a rearview video system, helps prevent backover crashes and protect our most vulnerable people — children and senior citizens. By providing an image of the area behind the vehicle, a backup camera helps the driver see behind the vehicle while in reverse. It’s important to remember that backup cameras are not a replacement for mirrors or turning around to look. As of May 2018, NHTSA requires this lifesaving technology on all new vehicles. Watch how it works.

An automatic crash notification system is designed to notify emergency responders that a crash has occurred and provide its location. In most cases, when the system detects that an air bag has deployed or that there’s been a dramatic and sudden deceleration, the system automatically connects to an operator, who will then be able to communicate with the driver. The operator is also able to collect basic information from the vehicle, without driver input, to provide to emergency responders so they can easily locate the scene of the crash. Automatic crash notification systems can reduce death and disability by decreasing the time it takes for emergency medical services to arrive at a crash scene and transport victims to a hospital.

The What and How of Adaptive Cruise Control

H itting the road for a long trip? Here's your new best friend: Adaptive Cruise Control (ACC) . This technology is becoming increasingly standard on many car models, and for good reason! ACC takes the stress out of highway driving by automatically adjusting your speed to match the car in front of you. It also helps maintain a safe following distance, making your drive more relaxing and secure.

How ACC works

Adaptive Cruise Control (ACC) uses a smart team of sensors. Most systems rely on a combination of a radar and a camera, depending on the carmaker. The radar acts like a super-sensitive echolocation system, sending out signals that bounce off the car in front of you to measure how far away it is. The camera works like an extra set of eyes, picking up visual details to confirm what the radar detects. Together, they create a more accurate picture of the road ahead.

One of the biggest perks of ACC is that it can help you avoid collisions . If the system detects a slowing car ahead or a potential hazard, it'll typically warn you with a light on your dashboard and an audible beep . If the system senses you're not responding and a collision is imminent, some ACCs can automatically apply the brakes to help slow you down.  

The development of ACC

While some advanced ACC systems can detect lane changes , it's important to remember they typically won't initiate them for you. However, they can make lane changes smoother by adjusting your speed to match surrounding traffic. Once the coast is clear, ACC helps you return to your preferred cruising speed, keeping your drive comfortable and controlled.

All in all, Adaptive Cruise Control (ACC) has become a game-changer for highway driving, offering a double dose of benefits: safety and comfort. ACC helps reduce the risk of collisions and takes the stress out of long stretches of road. It's a clear example of how the auto industry is constantly innovating to make driving safer and more enjoyable for everyone.

Honda The Other Side

Two Sides to Every Story

What is Adaptive Cruise Control (ACC)?

By Richard Craver Updated on May 7, 2023

ACC stands for Adaptive Cruise Control. It is a feature found in some Honda vehicles that automatically adjusts the vehicle’s speed to maintain a safe distance from the vehicle in front of it.

This allows the driver to set a desired speed and lets the vehicle automatically maintain a safe following distance, making highway driving more comfortable and less stressful.

Some Honda vehicles with ACC also include a “Low-Speed Follow” feature that allows the vehicle to follow at slower speeds, such as in heavy traffic.

Table of Contents

History Of ACC

The popularity of cruise control has grown since the 1970s, and it has become a standard feature in most cars. This simple but effective idea makes long drives on the freeway more enjoyable.

Adaptive cruise control, or ACC, is a great example of how these kinds of ideas evolve over time. A computer monitors the distance behind vehicles in front of you using radars mounted on the front of the car.

The computer will see a change in speed in the car ahead of you and prevent you from approaching too closely. Moreover, radars are also used to detect moving objects in front of the car and slow it down before a crash occurs.

Cruise Control Vs. Honda ACC: What’s The Difference?

How does Honda’s Adaptive Cruise Control (ACC) differ from traditional cruise control? With Honda Sensing®, this driver-assistive technology helps keep roadways safer by taking cruise control to a whole new level.

Driving with ACC is easier and more relaxing, whether you’re traveling for work or enjoying family road trips.

ACC works like regular cruise control, but Honda’s version allows you to set an interval between you and the vehicle ahead of you. Check out this video for more information about this feature.

What’s the Benefit Of Honda ACC?

A vehicle’s speed and following interval can be adjusted in response to the vehicle detected ahead with adaptive cruise control (ACC). Additionally, CVT models with Low-Speed Follow make driving in stop-and-go traffic easier.

The driver can set the desired speed with Adaptive Cruise Control (ACC), just like with a conventional cruise control system. In addition, ACC allows the driver to set an interval behind a detected vehicle and a desired speed.

• The driver can select a short, medium, or long distance behind the detected vehicle while engaged in Adaptive Cruise Control.
• When necessary, the ACC modulates the throttle and applies moderate braking to maintain the following interval.
• Even more functionalities can be added with Low-Speed Follow.
• ACC can stop the Honda Civic or any other Honda vehicle automatically when the preceding detected vehicle slows to a stop.
• The car will resume moving up to the ACC system’s previously set speed as soon as the driver pushes the cruise-control toggle switch toward RES/+ or -/SET or presses the accelerator.

How Do I Use My Honda Adaptive Cruise Control?

You can use ACC to make freeway driving more convenient, whether you’re traveling across the country or just across town.

Using the system, you can maintain a constant cruising speed, set a following distance between you and detected vehicles in front of you, and even help your Honda stop if a vehicle in front of you slows down.

How Do I Turn On Adaptive Cruise Control In My Honda?

You can enable Adaptive Cruise Control by following the steps below:

• On your steering wheel, press the MAIN button.
• ACC and LKAS (Lane Keeping Assist) will appear on the instrument panel.
• You can set your cruise speed if you are traveling below 25 miles per hour or if you have your foot on the brake pedal when the vehicle stops.
• On your steering wheel, press the SET/- button.
• The system will set a default cruise speed of 25 MPH.
• If you want to set your cruise speed higher than 25 MPH, press the SET/- button again after reaching your desired speed.

You’ll see your selected speed displayed on the instrument panel, along with a vehicle icon with four bars behind it indicating the set distance between you and the detected vehicles in front.

How Do I Adjust The Honda Adaptive Cruise Control Distance Settings?

With Honda ACC, you can choose from four different distance settings: short, medium, long, and extra-long.

You can adjust the distance setting on your steering wheel by pressing the interval button (vehicle with four bars).

Your interval setting will be displayed with the number of bars in the ACC icon on the instrument panel.

What The ACC Light Means

There is no difference between adaptive cruise control and regular cruise control. You can set a speed you want the car to maintain when you turn on cruise control. You can select the distance you want to maintain from cars ahead once the adaptive cruise control is engaged.

The computer will automatically apply the brakes to slow down your vehicle if it detects a gap closing in front of you and will warn you either with an audible alarm or flashing lights.

You should be prepared to step on the brakes if necessary since the brakes won’t be used at full power. The system will reduce the speed of your vehicle if the gap between them becomes too small. When the gap becomes too large, it will restore the speed of your vehicle.

Adaptive Cruise Control Dashboard Warning Light

It means dirt is covering the radar sensor and is preventing the radar from detecting the vehicle in front, which is why the Adaptive Cruise Control (ACC) light comes on with Low-Speed Follow (LSF).

Make sure the area around the radar sensor is clean. It may also come on during bad weather since the system may have difficulty detecting and may shut off automatically.

If the front sensor compartment temperature is too high while ACC with ASF is in operation and the green light is on, the system may cancel with a beep. The camera can be cooled down using climate control.

How Do You Reset Adaptive Cruise Control?

A Cruise Mode Selected display will appear on the instrument panel after pressing and holding down the interval button (you will see four bars behind it). You can reset the adaptive cruise control by pressing and holding the interval button again.

How Do You Get Adaptive Cruise Control To Turn Off?

Honda’s ACC system can be turned off in three ways:

• On the steering wheel, press the CANCEL button.
• On the steering wheel, press the MAIN button.
• Press the brake pedal or step on it.

Please note:  When your Adaptive Cruise Control system is equipped with Low-Speed Follow, and you depress the brake pedal, Adaptive Cruise Control will not be turned off.

Is It Safe To Drive When The ACC Light On?

The purpose of this system was to help drivers maintain a safe distance from vehicles in front of them. The cruise control should be turned off if the vehicle continually adjusts the speed while you are driving.

In addition to other safety systems, adaptive cruise control is also important for preventing accidents. Adaptive cruise control sensors can be affected by dirt and debris, so keep your car clean to avoid having any problems.

The certified technicians at the Honda dealership are always available to diagnose any problems you may be having with your adaptive cruise control.

Honda Models With ACC

• Adaptive Cruise Control is standard on all Honda Ridgeline trim levels.
• The new Honda Pilot comes with Adaptive Cruise Control in all trim levels, including the LX and Black Edition.
• Honda Passports come standard with Adaptive Cruise Control.
• Honda Odysseys come equipped with Adaptive Cruise Control as standard.
• The Honda CR-V comes standard with Adaptive Cruise Control on all models.
• Adaptive Cruise Control is standard on every Honda Insight trim.
• The Honda Civic Sedan comes standard with Adaptive Cruise Control.
• All Honda Accords come with Adaptive Cruise Control as a standard feature.

Final Words

By sensing the distance of the car ahead, the adaptive cruise control indicator light helps you drive at a safe speed. 

By setting a desired speed and letting the vehicle maintain a safe distance behind the driver, the Honda ACC feature makes highway driving more enjoyable and less stressful. As a whole, it can enhance the driving experience and be a convenient and useful feature.

The specified fuel consumption and emission data are determined in accordance with the measurement procedures prescribed by law. 1 January 2022, the WLTP test cycle completely replaced the NEDC test cycle and therefore no NEDC values are available for new type approved vehicles after that date.

This information does not refer to a single vehicle and is not part of the offer but is only intended for comparison between different types of vehicles. Additional equipment and accessories (additional components, tyre formats, etc.) can alter relevant vehicle parameters such as weight, rolling resistance and aerodynamics, affecting the vehicle's fuel consumption, power consumption, CO 2 emissions and driving performance values in addition to weather and traffic conditions and individual driving behavior.

Due to more realistic testing conditions, fuel consumption and CO 2 emissions measured according to WLTP will in many cases be higher than the values measured according to NEDC. As a result, the taxation of vehicles may change accordingly as of 1 September 2018. For further information on the differences between WLTP and NEDC, please visit www.volkswagen.de/wltp .

Causes Of Honda Adaptive Cruise Control Problem And How To Fix It

A Honda Adaptive cruise control problem can be a frustrating concern to deal with.

After all, you rely on this component for those long and tedious road trips. So, it is best to understand why this happens and what you can do to address it.

Since you rely on your cruise control for a more seamless and convenient experience while driving, you need to get this problem fixed sooner than later. Find out why your cruise control has stopped working and get the problem resolved for a stress-free ride.

What Causes A Honda Adaptive Cruise Control Problem

Generally, this issue is linked with your cruise control system. But there are also other common causes that you need to be aware of. 

Here are the more common culprits behind this issue and what you can do about it.

1. Blown fuse

Fuses control all electrical components in your vehicle. Hence, if you have a blown fuse that is connected to the cruise control system, then it can most definitely fail. And if the fuse is already damaged, your cruise control system will not function at all.

The good news is that you should be able to buy and replace your blown fuse. Check the manual to learn more about the fuse connected to your cruise control system and purchase a compatible component for a replacement.

2. Faulty brake pedal switch

Another possible cause of a cruise control problem is an issue with your brake pedal. This component turns your brake lights off and on, depending on the position of your pedal. When you press on the brake pedal, this disengages the cruise control system. 

Hence, if there are issues with your brake pedal switch, this causes the cruise control system to turn off. It may also cause the brake light to get stuck in the on position, which can confuse the drivers behind you. 

3. Speed sensor problems

Your speed sensors are on every differential or wheel. These monitor your speed to determine if there is a need for traction control. Your cruise control system has the speed sensors as one of its key components. So, when there is an issue with the sensor, this may cause the cruise control to malfunction, in addition to your speedometer acting up.

You can easily tell if there is a problem with your speed sensor by checking the dashboard. When you see the check engine light or the ABS warning light turn on, it means that your speed sensor is faulty.

4. Electrical Problems

Your cruise control is electronic. There are various parts that allow the system to function. So, if there is a problem with your cruise control, you should inspect the wiring harness, as well as related connectors, that may be having issues.

The voltage source also needs to be providing ample power to your cruise control system. Small faults can contribute to defects, so you may need to check on this. Sometimes a malfunction to the clock spring, a component behind your steering wheel, can also cause the cruise control to act strange.

Use your OBD II scanner to determine any error codes linked with your cruise control that may be responsible for these issues.

5. Damaged cable or hoses

And lastly, a cruise control problem may be linked with damages to the vacuum actuator or even the cable connecting to your throttle. This is the case with older vehicles. Damages to these parts will cause the cruise control to stop working completely. 

Further Information On The Honda Adaptive Cruise Control Problem

The cruise control initially appeared in vehicles back in the 1950s. Now, it is a staple component in modern vehicles. It is designed for maintaining a consistent speed when driving, which is useful especially in long distances.

With a cruise control, you can set your preferred speed and not have to step on your gas pedal. So, this reduces fatigue when you are driving for such a long distance. It also helps with fuel economy since you are able to maintain a steady flow of fuel.

If your cruise control system is having issues, then you need to determine what causes the failure. The repair cost depends on the affected parts and the extent of damage to the system. 

In the case of a broken brake switch or cruise control, the price can vary from $125 to as much as $350 . This includes the cost of replacement parts and labor. But if you only need to have the fuse changed, it should only cost you a few dollars. You may even replace the fuse yourself very quickly.

But if you have bigger problems with the cruise control such as a faulty actuator, the repair cost can be a bit steeper. For instance, replacing your actuator can set you back up to $700 or sometimes even more . 

While it may not appear to be an urgent fix when you have a cruise control problem, you most definitely want to get it addressed sooner than later. Otherwise, some other relevant issues affecting the performance may occur such as speedometer or acceleration problems.

Final Thoughts

Your cruise control includes a fuse, which may sometimes break and cause the system to fail. In the same way, there is a brake switch that also impacts the performance of your cruise control system. This sends signal to the system, which activates it when you apply the brakes. Thus, it is aware of when accelerating should cease. 

When your check engine light is turned on, this disables the cruise control system’s function. This is designed for safety purposes. So it is best to get your Honda Adaptive cruise control problem fixed sooner than later. By doing so, you can prevent performance issues and make sure no further damages occur over time.

What if along with the adaptive cruise control failing, the road mitigation departure as well as brake system light also turns on?

If the adaptive cruise control (ACC) fails and you also notice the road mitigation departure and brake system lights turning on, it could indicate a more significant issue with your vehicle’s safety systems. In this case, it is recommended to take the following steps:

1. Check the Owner’s Manual: Refer to your vehicle’s owner’s manual to understand the specific meaning of these warning lights. It may provide you with specific instructions or information about the problem.

2. Inspection: Take your vehicle to an authorized Honda service center or a qualified mechanic for a comprehensive inspection. They will be able to diagnose the issue using specialized diagnostic equipment and software.

3. System Reset: Sometimes, a temporary glitch or error in the system can cause multiple warning lights to illuminate. Try performing a system reset by disconnecting the vehicle’s battery for a few minutes and then reconnecting it. This may clear the fault codes and reset the systems. However, keep in mind that this is a temporary solution, and the underlying issue needs to be addressed.

4. Addressing Faulty Components: Depending on the diagnosis, the faulty components related to the ACC, road mitigation departure, and brake system will need to be repaired or replaced. This could involve issues with sensors, wiring, actuators, or control modules. Only a qualified technician can accurately identify and resolve these problems.

It is crucial to address these issues promptly, as they directly affect the safety and functionality of your vehicle’s advanced driver assistance systems. Following the manufacturer’s recommendations and seeking professional assistance is the best course of action in such situations.
