How to Release ABS Lock on a Car?
1 Answers
Clean the dirt on the wheel speed sensor and adjust the gap between the wheel speed sensor and the signal gear ring to restore normal operation. Alternatively, check the wiring connections and reconnect any loose ones. ABS Working Principle: During braking, ABS quickly determines the wheel lock state based on the speed signals from each wheel speed sensor. It closes the normally open input solenoid valve on the wheel that is starting to lock, keeping the braking force constant. 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 of 20%), ensuring the best braking effect and the safest driving. ABS Functions: Maximize 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.
