What does TCS mean in cars?
1 Answers
TCS in cars stands for Traction Control System, which consists of: engine control unit (ECU), transmission control unit (TCU), ABS control unit, and wheel speed sensors. The working principle of TCS is: 1. When the TCS control unit detects wheel slip (driven wheel speed higher than other wheels), it notifies the engine control unit; 2. The engine control unit reduces throttle opening to decrease power output and adjusts ignition timing; 3. After the engine control unit reduces fuel injection to decrease power, the transmission control unit forces upshifts to reduce driving force; 4. The ABS pump solenoid valves activate to apply braking force to the slipping wheels, eliminating tire slip.
