What does TCS mean on a car?

[KalebMarie]

TCS on a car stands for Traction Control System, which ensures that the vehicle obtains optimal traction under various driving conditions. The control device of the Traction Control System is a computer that monitors the speed of all four wheels and the steering wheel's turning angle. When the car accelerates and the computer detects an excessive speed difference between the driving wheels and non-driving wheels, it immediately determines that the driving force is too high and sends a signal to reduce the engine's fuel supply, thereby decreasing the driving force and reducing the slip rate of the driving wheels. The Traction Control System is also known as the Anti-Slip Regulation (ASR) system. When braking on slippery surfaces, the wheels may skid, potentially causing a loss of directional control. Similarly, during startup or rapid acceleration, the driving wheels may also skid, especially on icy or slippery roads, leading to dangerous loss of control. The Traction Control System is specifically designed to address these issues.
