What does tc mean in a car?

[StJuliet]

tc stands for Traction Control System, which is a very important system in a car. Here is the relevant introduction: 1. Traction Control System, abbreviated as TCS, is also known as ASR or TRC. 2. It can control the car's traction by reducing the throttle opening to decrease engine power or by using the brake to control wheel slip. In cars equipped with tc, the mechanical connection between the accelerator pedal and the throttle of the gasoline engine is replaced by an electronic throttle device. When the sensor sends the position of the accelerator pedal and the wheel speed signal to the control unit, the control unit generates a control voltage signal. The servo motor adjusts the throttle position accordingly, and then feeds back the position signal to the control unit for timely adjustment of the brake. 3. The computer uses the steering wheel angle sensor to understand the driver's steering intention, and then uses the left and right wheel speed sensors to detect the speed difference between the left and right wheels; thus, it determines whether the car's steering degree matches the driver's steering intention. If understeer is detected, the computer immediately determines that the driving wheel's driving force is too high and issues a command to reduce the driving force to achieve the driver's steering intention.
