What does ABS braking mean?
1 Answers
The full name of automotive ABS is Anti-lock Braking System. Its function is to automatically control the braking force of the brake during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling while sliding (with a slip ratio of about 20%), ensuring that the adhesion between the wheels and the ground remains at its maximum. Classification of ABS: ABS is mainly classified based on channels. In ABS, the brake pipelines that can independently adjust braking pressure are called control channels. ABS systems are divided into four-channel, three-channel, two-channel, and one-channel configurations. One-channel ABS: Also known as single-channel ABS, it features a single brake pressure modulator in the rear wheel brake line and a wheel speed sensor installed on the rear axle differential (sometimes one on each rear wheel). Two-channel ABS: This type of ABS struggles to balance directional stability, steering control, and braking efficiency, and is rarely used today. Three-channel ABS: It independently controls the two front wheels, while the two rear wheels are controlled together based on the low-select principle (i.e., both wheels are controlled by one channel to ensure the wheel with less adhesion does not lock up), also known as hybrid control. Four-channel ABS: Equipped with four wheel speed sensors, it includes a brake pressure modulator in the pipeline to each wheel's brake cylinder for independent control, forming a four-channel control system.
