What is the role of the ABS system?
1 Answers
The functions of the ABS system 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 the tires and the ground, reducing tire wear. During braking, the ABS system quickly determines the wheel lock-up state based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve for the wheel that is starting to lock up, and maintains the braking force. If the wheel continues to lock up, 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 up due to excessive braking force. This keeps the braking state at the optimal point (slip ratio S of 20%), achieving the best braking effect and the highest level of driving safety.
