Anti-lock braking system (ABS) is a car safety system that automatically controls the braking force of the brakes during braking to prevent the wheels from locking. During braking, the ABS system maintains the adhesion between the wheels and the road surface, allowing the vehicle to remain stable during braking, reducing the risk of sideslip and loss of control.
The working principle of the ABS system is based on sensors and brake adjusters. During braking, the wheel speed sensor transmits the rotational speed signals of the wheels to the electronic control unit (ECU), which uses these signals to determine whether the wheels are about to lock up. If the ECU judges that the wheels are about to lock, it will automatically adjust the braking force of the brakes through the brake adjuster, so that the brakes generate less braking force to prevent the wheels from locking. This process repeats quickly, ensuring that the wheels maintain a certain amount of rolling friction at all times, allowing the vehicle to remain stable when braking.
The role of the ABS system is mainly reflected in the following aspects:
1.Prevent wheel locking: During braking, the ABS system can automatically control the braking force of the brakes to prevent the wheels from locking completely, thus maintaining the adhesion between the wheels and the road surface.
2.Maintain vehicle stability: The ABS system can prevent the vehicle from skidding and losing control when braking, so that the vehicle remains stable when braking.
3.Reduced braking distance: The ABS system maintains the adhesion between the wheels and the road surface, which reduces the braking distance and shortens the downtime.
4.Improve safety: ABS system can improve the safety of vehicles and reduce the probability of traffic accidents.
In short, ABS anti-lock braking system is an important automotive safety system, which can improve the stability and safety of the vehicle and reduce the probability of traffic accidents. With the continuous improvement of people's requirements for car safety, ABS system has become one of the must-have configurations of modern automobiles.
