What does TCS on a car mean?

[VonDelaney]

TCS on a car stands for Traction Control System. When the car accelerates, TCS keeps the skidding within a certain range, preventing the drive wheels from slipping rapidly, thereby improving traction and maintaining the vehicle's driving stability. When driving on slippery surfaces, the drive wheels are prone to skidding during acceleration, rear-wheel-drive cars are more likely to fishtail, and loss of directional control can cause the vehicle to veer off course. TCS helps mitigate this phenomenon during acceleration, ensuring the vehicle steers along the correct path. There are two methods by which TCS controls wheel skidding: one is by utilizing the braking system to increase the brake fluid pressure on the skidding wheel, applying appropriate braking to limit wheel slip; the other method involves not only using the braking system but also controlling engine power output by delaying ignition timing, reducing fuel injection, or adjusting valve opening to decrease the drive force on the wheels and prevent them from slipping.
