What is the function of ABS?

[VanBrynlee]

ABS functions: Maximize the effectiveness of the brakes, shorten 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 tires and the ground, reducing tire wear. ABS working principle: During braking, ABS quickly determines wheel lock-up status based on speed signals from each wheel speed sensor, closing the normally open input solenoid valve for wheels beginning to lock to maintain braking force. If wheels continue to lock, the normally closed output solenoid valve opens, rapidly decreasing braking pressure on that wheel through the direct connection to the brake fluid reservoir, preventing complete wheel lock-up due to excessive braking force. This keeps the braking state at the optimal point (slip ratio S at 20%), achieving the best braking effect and maximum driving safety.
