How to Brake When Driving a Vehicle with ABS System

[LaPreston]

When braking a vehicle equipped with an ABS system, you can firmly press the brake pedal to apply the brakes. How ABS Works: During braking, the ABS quickly determines the wheel lock-up status based on speed signals from each wheel speed sensor. It closes the normally open input solenoid valve on the wheel that begins to lock, maintaining the braking force. If the wheel continues to lock, the normally closed output solenoid valve opens, causing the brake pressure on that wheel to rapidly decrease due to the direct connection to the brake fluid reservoir, preventing complete wheel lock-up from excessive braking force. This keeps the braking state at the optimal point (20% slip rate S), achieving the best braking performance and maximum driving safety. Functions of 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 intense friction between the tires and the ground, reducing tire wear.
