What is the Principle of the Vehicle Anti-Skid System?
2 Answers
The principle of the vehicle anti-skid system is as follows: Through the ABS and ASR electronic control units, based on the signals sent by the wheel speed sensors, the system calculates and analyzes to determine the wheel slip rate and the vehicle's driving speed. The electronic control unit then adjusts the throttle opening and brake pressure to regulate the wheel slip rate, preventing the vehicle from skidding sideways during driving. Situations where the anti-skid system needs to be turned off include: 1. When the vehicle is stuck in mud or during off-road driving; 2. When encountering uphill slippage on rainy or snowy days; 3. When anti-skid chains are installed on the vehicle tires; 4. During aggressive driving or vehicle drifting.
The anti-skid system primarily works by installing sensors on the vehicle to monitor wheel rotation and body posture, such as detecting whether the wheels are slipping or the body is tilting. Once signs of loss of control are detected, the computer immediately intervenes by braking individual wheels or reducing engine power to help the vehicle return to a stable state. The entire process is extremely fast, and drivers may only feel the brakes automatically tapping to correct the direction. Having played with many car models, I think this system is like an invisible assistant, preventing rollovers or skidding off the road at critical moments. However, it's important to remember that it cannot replace careful driving—don’t rely too much on it during rain or sharp turns. Most modern new cars come standard with this feature, making it a significant safeguard for driving safety.
