What does TCS mean in a car?

Traction Control System, abbreviated as TCS, is also known as ASR or TRC. Its function is to enable the car to obtain optimal traction under various driving conditions. Additional Information: 1. The control device of the traction control system is a computer that detects the speed of the four wheels and the steering angle of the steering wheel. When the car accelerates, if the computer detects a significant speed difference between the drive wheels and non-drive wheels, it immediately determines that the driving force is excessive and sends a signal to reduce the fuel supply to the engine, thereby decreasing the driving force and reducing the slip rate of the drive wheels. The computer uses the steering angle sensor to understand the driver's steering intention and then detects the speed difference between the left and right wheels using the wheel speed sensors to determine whether the car's steering degree matches the driver's intention. If understeer (or oversteer) is detected, the computer immediately determines that the driving force on the drive wheels is excessive and sends a command to reduce the driving force to align with the driver's steering intention. 2. The basic working principle of TCS is: during car braking, the wheel speed sensor first measures an AC voltage signal proportional to the speed of the braking wheel and sends this signal to the electronic control unit (ECU). The computing unit in the ECU calculates the wheel speed, slip rate, and the acceleration or deceleration of the wheel. The control unit in the ECU then analyzes and compares these signals before issuing a braking pressure control command to the pressure regulator.
