Brake Assist, a new active safety innovation from Toyota Motor Corporation, enhances braking performance in emergency situations. Beginning with the new models that will be released this spring, Toyota automobiles will come equipped with brake assist.
If the driver doesn’t step on the brake pedal firmly enough, Brake Assist perceives a fast push of the brake pedal as emergency braking and adds additional braking force.
Drivers, especially novice ones, frequently panic in emergency situations and don’t press the brake pedal all the way down. However, a brake assist system that merely boosts braking force when the foot is barely depressed would interfere with brake control while driving normally. Drivers might also grow accustomed to such a device and might not depress the brake pedal hard enough in an emergency.
In order to determine whether the driver is attempting to brake quickly or not, Toyota’s Brake Assist system measures the speed and force with which the brake pedal is pressed. It then applies additional braking pressure to maximize braking performance for both conventional and anti-lock brake system (ABS) equipped vehicles. As a result, any driver can brake within the same distance as a highly trained driver by reducing the emergency braking distance by around 30%.
The timing and level of braking assistance provided by Brake Assist are designed to guarantee that the driver does not notice anything strange about the braking process, which is a particularly crucial aspect. The technology consequently scales back its help when the driver purposefully eases off the brake pedal.
- In an emergency, a driver who is panicked may brake fast yet insufficiently to produce the necessary braking power.
- Such drivers frequently ease up on the brake pedal too early in the braking phase as opposed to continuing to push the brake pedal.
- Even when the brake pedal is not being pressed firmly enough, the Brake Assist system boosts braking power when it detects that the driver is braking quickly.
- The Brake Assist system also decreases the amount of braking help it offers when the driver purposefully eases up on the brake pedal, preventing the driver from noticing any aberrant braking behavior.
Roughly 50% of motorists who are attempting an emergency stop on a dry road do not apply adequate force to the brakes.
This shows whether or not motorists exert enough pressure to get the brakes up to the point right before they lock (for non-ABS vehicles).

What does brake assistance do?
Drivers’ reaction times frequently don’t correspond to how rapidly they must act to prevent a collision. When drivers stomp on the brakes, electronic braking aid detects this and provides the maximum amount of force to the brakes to help the vehicle stop as quickly as possible.
As you drive, be sure to maintain a safe following distance from vehicles in front of you.
What It Does Not Do: Your car won’t stop on its own. (Read about automated emergency braking)
Is brake aid beneficial?
Both the relatively high effort levels needed for maximum braking and the “buzzing” feedback provided by the brake pedal during ABS operation are unfamiliar to many drivers. If an emergency arises, a delayed response and insufficient braking force may not give the driver the time or space to stop before an accident.
EBA is made to recognize these “panic stops” and quickly apply the maximum amount of braking force. It analyzes braking behavior by counting how frequently the brake pedal is depressed.
In the event of an emergency, the system will begin full braking before the driver can even move their foot. Accident probability can be decreased by minimizing emergency stopping distances, particularly the frequent “nose-to-tail” event.
The safety of the vehicle and its occupants is increased with an electronic system that can recognize emergency braking operations and automatically increase braking effort. This technology can also cut stopping distances by up to 70 feet (21 meters) at 125 mph (201 km/h).

Brake Assist measures how quickly the brake pedal is depressed to determine when emergency braking is necessary. Some systems also consider how quickly the accelerator pedal is depressed, pre-tensioning the brakes in the event of an accelerator pedal “panic release.” The Brake Assist system automatically develops maximum brake boost when panic braking is recognized to counteract a driver’s propensity to brake too gently. As a result, Brake Assist has been demonstrated to significantly shorten stopping distance (up to 20% in some trials).
Due to its reliance on human input, brake assist is neither an autonomous emergency braking system nor a collision avoidance system.

Is brake assistance crucial?
Thanks to brake assist, a form of technology that enables your vehicle to stop if you are unable to respond in time, many collisions have been prevented throughout the years. Electronic sensors in brake assist can intervene if you’re about to crash and start working faster than you can.
According to studies, brake assist is a worthy investment because it helps to avert hundreds of collisions every year. Because brake assist monitors your typical driving tendencies, it can determine when it has to intervene if you aren’t paying attention to the road in front of you.
Brake assist has proven to be so successful in averting collisions that it is now a requirement for all cars in Europe. Brake assist might soon be required in North America, where drivers are responsible for 3,000 fatalities annually because they were unable to stop in time.
You probably aren’t paying close attention to the road ahead if you’re fatigued or distracted, which increases your risk of being in an accident. Although brake assist cannot ensure your safety, it does help to reduce collisions and increases your sense of security when driving.
Is Toyota equipped with automatic braking?
Put the brake on as quickly as you can. The Toyota Pre-Collision System may apply the brakes automatically or deploy them fully with brake help if the alarms do not allow you to slow down or stop your car.
Can brake assistance be disabled?
The obvious benefit of AEB is that it can prevent car accidents or at least decrease their damage. There are certain drawbacks to AEB, though. One is the chance for error. Unnecessarily slamming on the brakes in response to a false positive could cause excessive panic and raise the risk of hitting a car coming up behind you in the back. On the other hand, an AEB system’s flaw can go unnoticed and prevent it from working when it’s most required. Another debatable drawback of AEB is that it can make drivers complacent. Why bother paying as close attention if they know their car might stop on its own? These are certainly extreme cases, but they shouldn’t cast any doubt on the overall advantages of AEB.
Can You Turn Off Automatic Emergency Braking?
Some motorists favor having total control. Active safety and driver assistance systems, including AEB, may typically be turned off in vehicles that have them. Some enable some degree of customization, such as altering the sensitivity of AEB, the timing and manner in which FCW activates, or the distance at which it “looks” for impediments. Others keep it always on and prepared to act in case the driver isn’t.
Is Automatic Emergency Braking Worth It?
AEB should be a priority for you if preventing pricey or dangerous car accidents is important to you. Even drivers with the highest levels of tuning can appreciate this crucial feature. It serves as a useful backup in erratic traffic situations. Some automakers charge an additional fee for AEB, but considering the potential financial and health costs of a collision, this fee seems reasonable. The good news is that AEB is increasingly being included as standard equipment in cars.
Does Automatic Emergency Braking Really Work?
AEB systems are now available from all automakers, yet none of them advocate driving while paying attention to the road. The technology is not sufficiently developed to identify and lessen every possible harm. However, it has been shown to have a significant safety benefit. The IIHS and NHTSA both advise against using AEB. There won’t be a substitute for paying full attention to the road ahead until completely autonomous vehicles are available. But when a fraction of a second or a few feet might mean the difference, AEB really shines.
What Are the Different Automatic Emergency Braking Systems?
AEB is branded by some automakers using their own brands. Don’t be misled by marketing; although it may occasionally go by different names, AEB really serves the same role in all vehicles. According to their respective manufacturers, these are the more typical AEB systems:
- Pre Sense Front or Pre Sense City, according to Audi
- BMW’s Active Driving Assistant or Active Guard safety suites include Frontal Collision Warning with City Collision Mitigation.
- Collision Mitigation Braking System (CMBS) for automobiles; a component of the AcuraWatch security system
- Full-Speed Forward Collision Warning Plus for Alfa Romeo
What about the brake assistance?
A driver’s reaction time and the pressure they apply to the brake pedal may not be sufficient for a swift, quick stop in an emergency braking situation. In a crisis, some drivers, particularly novice ones, may panic and not apply enough force to the brakes.
Drivers may find themselves in a dangerous scenario if the brakes aren’t applied with the force necessary to stop the car. Brake assist comes into play to aid the driver when there is insufficient brake pedal pressure.
A brake assist system is made to shorten the distance that must be stopped completely in an emergency. Without a brake assist device, cars need to stop much more slowly before coming to a complete stop. Due to the improvement in driver safety since its creation in the 1990s by Mercedes, this technology is now a requirement for automobiles.
Together with the ABS, the brake assist system gives the driver complete control of the vehicle during braking, allowing them to steer the vehicle safely and avoid obstacles. The driver may apply much greater forces to the braking system using a brake assist system than they could do with simply their foot alone.
If the system believes you need to make a quick stop, the brake assist feature will automatically engage and may even be enabled if the driver softly presses the brake pedal. Brake assist systems have improved in efficiency and accuracy as modern cars become safer, adding additional pressure when necessary during an emergency stop.
Automatic Brake Assist Systems
The use of an active brake assist system has increased in popularity in contemporary vehicles as technology in these systems advances. With the development of braking systems, cars can now come to an abrupt stop without the driver depressing the brake pedal.
Drivers can avoid collisions with unforeseen roadside hazards with the use of active braking assist devices. Additionally, it can stop accidents caused by distracted drivers. Its response time is far quicker than the driver’s.
These active brake assist systems employ radar and video data technologies to scan its environment and provide the necessary amount of braking force to avoid any hazards they identify. Radar and camera technology can detect pedestrians as well as stationary and moving vehicles.
What distinguishes brake assistance from ABS?
While brake assist makes sure the driver has access to the most amount of braking force possible, ABS is responsible for stopping or slowing the automobile down. ABS gets its braking power from the driver’s foot. This has the drawback that human error is possible.
