What does TSC mean in cars?

Traction Control System (TSC) is an introduction to the Traction Control System, with its full English name being Traction Control System. Like ABS and ESP, it belongs to the active safety systems of a car. The Traction Control System can prevent the drive wheels from spinning when the vehicle is driving on slippery roads such as snow, allowing the vehicle to start and accelerate smoothly. Especially on snowy or muddy roads, the Traction Control System ensures smooth acceleration performance and prevents the vehicle from skidding or fishtailing due to wheel spin. The control device of the Traction Control System is a computer that monitors the speed of all four wheels and the steering angle of the steering wheel. When the car accelerates, if the computer detects a significant difference in speed 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 wheel angle sensor to understand the driver's steering intention and then detects the speed difference between the left and right wheels using wheel speed sensors. This helps determine whether the vehicle's steering response matches the driver's intention. If understeer (or excessive oversteer) is detected, the computer immediately determines that the driving force on the drive wheels is too high and reduces it to align with the driver's steering intent.
TSC in cars refers to the Traction Control System. Simply put, it's a device that prevents the vehicle from skidding. For example, if you're driving on muddy terrain on a rainy day and the tires start to spin, TSC will automatically intervene—either by reducing the engine's power output or by braking the skidding wheel individually, immediately helping to stabilize the car. This system works in perfect harmony with the ABS braking system and is now standard in most family cars priced around 100,000 yuan, especially front-wheel-drive vehicles that particularly need it. Last time my SUV was climbing a snowy slope, I clearly felt the system intervene within half a second of the tires starting to slip, and the car steadily moved forward with a firm grip. I genuinely find this feature very practical.
