What is the Function of the Anti-Slip Regulation System?
1 Answers
The function of the Anti-Slip Regulation (ASR) system is to control wheel slippage within a certain range during vehicle acceleration, thereby preventing the drive wheels from spinning excessively. Its primary purposes are: 1) to enhance traction, and 2) to maintain driving stability. Further details are provided below: 1. Definition: The Automotive Anti-Slip Regulation System (Acceleration-Slip Regulation or Traction-Control-System), abbreviated as ASR or TCS, is a slip control system developed after ABS. It represents an advanced evolution and crucial supplement to ABS functionality. The ASR system is closely related to the ABS system and is typically used in conjunction with it, forming an active safety system for vehicle operation. 2. Working Principle: On slippery road surfaces, vehicles without ASR are prone to wheel spin during acceleration. Rear-wheel-drive vehicles may experience fishtailing, while front-wheel-drive vehicles may suffer from loss of steering control. With ASR, these phenomena are either prevented or significantly mitigated during acceleration. During cornering, if drive wheel slippage occurs, the entire vehicle may drift to one side. The ASR system helps maintain the correct turning trajectory. In ASR-equipped vehicles, the mechanical linkage between the accelerator pedal and the throttle valve (or diesel injection pump lever) is replaced by an electronic throttle control system. When sensors transmit throttle pedal position and wheel speed signals to the control unit (CPU), the unit generates control voltage signals. Servo motors adjust the throttle position (or diesel pump lever position) accordingly, with position feedback sent back to the control unit for timely brake adjustment.
