What is the main function of car ABS?
1 Answers
ABS main functions: Fully utilize the effectiveness of the brakes, shortening 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, 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 single-channel types. Single-channel ABS: Also called one-channel ABS, it has a brake pressure regulator installed in the rear wheel brake main pipe, with a wheel speed sensor mounted on the rear axle differential (or 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 traction does not lock), also known as hybrid control. Four-channel ABS: Equipped with four wheel speed sensors, each brake pipeline leading to the four wheel brake cylinders has a brake pressure regulator for independent control, forming a four-channel control system.
