What is the purpose of vehicle anti-skid control?
2 Answers
Vehicle anti-skid control function: Primarily controls the longitudinal and lateral stability of the vehicle to ensure it moves according to the driver's intentions. When tires are about to lock up during braking, the ESP system performs "mechanical cadence braking" with hundreds of braking actions per second. This allows the vehicle to maintain steering control via the steering wheel even during full-force braking. The ESP works in coordination with the engine ECU - when drive wheels slip, the engine ECU immediately reduces throttle intake to lower engine RPM and decrease power output, while the ESP ECU applies braking to the slipping drive wheels. This helps minimize slippage and maintain appropriate power output for optimal tire-road traction.
I've been driving for over thirty years, and the anti-skid system is incredibly useful, especially on rainy or icy roads. I remember one time during heavy rain, my wheels suddenly skidded while taking a high-speed turn, but the system instantly intervened, automatically applying brakes and adjusting power distribution, stabilizing the car. Without it, I probably would have veered off the road. This system mainly relies on sensors to detect vehicle dynamics. Once signs of skidding are detected, it adjusts braking force to individual wheels or reduces engine output to prevent loss of control. For seasoned drivers like me who frequently take long trips, it significantly enhances safety, preventing accidents caused by skidding on slippery surfaces. In everyday driving, it helps maintain proper vehicle posture, particularly during sharp turns or emergency maneuvers, eliminating worries about rollovers and giving me peace of mind. Nowadays, this feature is pretty much standard in new cars—it's an absolute must-have for safe driving.
