What is the role of car ABS?
1 Answers
ABS system functions: Maximize the effectiveness of the brakes, reducing braking time and distance. Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. Allow steering during emergency braking, providing good steering control. Avoid severe friction between tires and the ground, reducing tire wear. ABS classification: ABS is mainly classified by channels. In ABS systems, the brake pipelines that can independently adjust brake pressure are called control channels. ABS control channels are divided into four-channel, three-channel, two-channel, and one-channel types. One-channel ABS: Also called single-channel ABS, it has one brake pressure regulator in the rear wheel brake main pipe, with one wheel speed sensor installed on the rear axle differential (some have one on each rear wheel). Two-channel ABS: This type of ABS struggles to balance directional stability, steering control, and braking effectiveness, and is rarely used today. Three-channel ABS: 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), also called hybrid control. Four-channel ABS: Has four wheel speed sensors, with one brake pressure regulator in each pipeline leading to the four wheel brake cylinders, enabling independent control and forming a four-channel control configuration.
