Can ABS Cause Side Slip When Steering During Emergency Braking?

[CaydenDella]

ABS does not cause side slip when steering during emergency braking. This is because ABS prevents the wheels from locking up during emergency braking, allowing the vehicle to maintain good directional stability even under hard braking. How ABS Works: During braking, 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 for wheels that begin to lock, keeping the braking force constant. If the wheel continues to lock, the normally closed output solenoid valve opens, causing the braking pressure on that wheel to drop rapidly as it connects directly to the brake fluid reservoir, preventing complete wheel lock-up due to excessive braking force. This keeps the braking state at the optimal point (20% slip ratio S), achieving the best braking performance and maximum driving safety. Functions of ABS: Maximizes brake efficiency, reducing braking time and distance. Effectively prevents vehicle side slip and fishtailing during emergency braking, ensuring excellent driving stability. Allows steering during emergency braking, providing good steering control. Avoids severe friction between tires and the road surface, reducing tire wear.
