What role does the ABS system play?

[NicoleLynn]

ABS system functions include: Maximizing the effectiveness of the brakes, reducing braking time and distance; effectively preventing vehicle skidding and fishtailing during emergency braking, ensuring excellent driving stability; allowing steering during emergency braking, providing good steering control; avoiding intense friction between tires and the ground, reducing tire wear. During braking, the ABS system quickly determines the wheel lock-up state based on speed signals from each wheel speed sensor, closing the normally open input solenoid valve for the wheel that begins to lock, maintaining constant braking force. If the wheel continues to lock, the normally closed output solenoid valve is opened, causing the braking pressure on that wheel to rapidly decrease due to the direct connection to the brake fluid reservoir, preventing the wheel from completely locking due to excessive braking force. This keeps the braking state at the optimal point (slip rate S at 20%), resulting in better braking performance and ensuring driving safety.
