What is the definition of automotive ABS?
1 Answers
ABS, the full name 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 and sliding (with a slip ratio of about 20%), ensuring that the adhesion between the wheels and the ground is at its maximum. Classification of ABS: ABS is mainly classified based on channels. In ABS, the brake pipelines that can independently adjust the braking pressure are called control channels. The control channels of ABS devices are divided into four-channel, three-channel, two-channel, and one-channel types. One-channel ABS: Also known as single-channel ABS, it involves setting a brake pressure regulator in the rear wheel brake main pipe and installing a wheel speed sensor on the rear axle differential (some models may have one installed 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 nowadays. Three-channel ABS: It involves independent control of the two front wheels and combined control of the two rear wheels based on the low-select principle (i.e., both wheels are controlled by one channel, ensuring that the wheel with less adhesion does not lock up), also known as hybrid control. Four-channel ABS: It includes four wheel speed sensors, with a brake pressure regulator device installed in the pipeline leading to each of the four wheel brake cylinders, enabling independent control and forming a four-channel control configuration.
