What is the use of brake assistance and the principle of brake assistance?

The brake assist system has a great role in the daily driving process. It can judge whether it is an emergency brake and make an effective braking action, which greatly improves the safety of driving.

      Brake assist profile

      Brake assist is generally called EBA or BAS. Its working principle is that the sensor recognizes and judges whether emergency brake program is introduced or not by recognizing the driver's pedaling condition. This system can immediately inspire the maximum brake pressure to achieve the highest possible value. Braking effect, to achieve the desired braking effect to stop the occurrence of traffic accidents.

Brake assist principle

      ABS can shorten the braking distance and prevent the vehicle from losing control during braking, thus reducing the possibility of accidents. However, in the case of emergency braking, the driver is often unable to quickly trigger ABS to waste braking time due to lack of decisive braking or insufficient treading force, thereby failing to achieve the desired effect. For this reason, the automotive engineers designed the brake assist, which means that the existing ABS has certain intelligence. When the brakes are fast and powerful, the BAS judges the driver in emergency braking and let the ABS work, and quickly increase the braking force. .

      Brake assist is divided into mechanical and electronic control. The mechanical brake assist is actually a slight modification on the basis of the ordinary brake booster. When the braking force is not great, it acts as an afterburner. As the brake force increases, the booster pressure chamber Increased pressure starts ABS. An electronically actuated brake-assisted brake booster has a sensor that sends information about the pedal stroke and travel speed to the ABS controller. If the ABS controller determines that it is an emergency brake, it opens the booster solenoid valve. Increasing the pressure in the pressure chamber has already provided sufficient assistance.

      The car has a brake assist system that will be safer and reduce the possibility of accidents. The system can automatically determine that the driver is taking an emergency brake and reacts quickly to increase the braking force and stop the car.

      The main role of brake assist system

      1. Used to prevent the wheels from locking when the brakes are applied.

      2. Different axle load transfer occurs when the car is braked. Automatically adjust the front and rear axle braking force distribution ratio to improve braking performance.

      3. Determine the driver's braking action, increase the braking force during emergency braking, and shorten the braking distance.

      4. When the car has wheel slipping, rolling or tires lose adhesion at the moment, while reducing the engine speed, a specific purpose of braking control for individual wheels, and eventually the car into the normal track, thus avoiding the wheel out of control And the danger.

      5. By controlling the size of the driving force, the sliding rate of the driving tire is reduced, bumping is prevented, and the car tends to be stable.

      Brake Assist System Benefits

      Based on the speed and force acting on the brake pedal, determine if the emergency brake is on.

      Even if the brakes on the brakes are weak, big brakes can occur.

      When the pedal is released, the assist force is automatically reduced and the sense of discomfort when braking is reduced.
