What is the Principle of the Anti-Skid System?
2 Answers
Here is the relevant introduction about the car anti-skid system: 1. Anti-skid principle: The car anti-skid system uses the ABS/ASR electronic control unit to determine the wheel slip rate and vehicle speed by calculating and analyzing the signals from the wheel speed sensors. The electronic control unit adjusts the wheel slip rate by controlling the throttle opening and brake pressure to prevent the car from skidding during driving. 2. Anti-skid system: For cars equipped with an anti-skid system, the system is enabled by default when the car is powered on. The anti-skid system mainly analyzes the information from sensors to ensure the best dynamic balance of the car during driving. The anti-skid system can guarantee the stability of the car, especially when the car is in a state of oversteering or understeering.
I'm passionate about studying automotive electronic systems, and the anti-skid control system is truly the essence of vehicle stability control. When wheels slip on wet roads or during rapid acceleration, the system uses wheel speed sensors to monitor the rotational speed differences of each tire in real-time. If it detects a wheel spinning too fast, indicating insufficient traction, the control unit intervenes. It automatically adjusts braking force to the slipping wheel while reducing engine torque output to prevent vehicle fishtailing or deviation. This entire process is fully automatic, requiring the driver only to steer. Modern vehicles also incorporate steering angle sensors and gyroscopes, enabling early detection of skid tendencies for preventive intervention, which proves particularly effective during high-speed cornering.
