Can ABS Emergency Braking Cause Skidding When Turning?
1 Answers
Driving a vehicle equipped with an ABS system while turning during emergency braking may cause skidding. This is because vehicles with ABS systems allow the steering wheel to remain functional without locking up when the brakes are applied. Therefore, excessive steering input can indeed lead to skidding. More details are as follows: Definition: The Anti-lock Braking System (ABS) is designed to automatically control the braking force during vehicle braking, preventing the wheels from locking up. It maintains a state where the wheels are both rolling and slipping (with a slip ratio of about 20%), ensuring maximum traction between the wheels and the road surface. Principle: During braking, ABS rapidly determines the wheel lock-up status based on speed signals from each wheel speed sensor. It closes the normally open input solenoid valve for the wheel that is beginning 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 drop rapidly due to the direct connection to the brake fluid reservoir. This prevents the wheel from completely locking up due to excessive braking force. Maintaining the optimal braking state (with a slip ratio S of 20%) ensures the best braking performance and the highest level of driving safety.
