What is the Function of Car ABS?
1 Answers
The functions of car ABS: 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 excellent steering control. Avoid severe friction between the tires and the ground, reducing tire wear. Classification of ABS: 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 one-channel types. One-channel ABS: Also known as single-channel ABS, it has a brake pressure regulator installed in the rear wheel brake main pipe and a wheel speed sensor 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 effectiveness and is rarely used today. Three-channel ABS: Independently controls the two front wheels while controlling the two rear wheels 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 wheel brake cylinder pipeline has a separate brake pressure regulator for independent control, forming a four-channel control system.
