TRC refers to the Traction Control System. It is the abbreviation of Traction-control-system. Its function is to enable the car to obtain optimal traction under various driving conditions. Introduction to Traction Control System: The control device of the traction control system is a computer, which detects the speed of the four wheels and the steering angle of the steering wheel. The Traction Control System, abbreviated as TCS, is also known as ASR or TRC. Its role is to ensure the car achieves optimal traction in all driving conditions. Working principle of Traction Control System: It can control the vehicle's traction by reducing the throttle opening to decrease engine power or by using the brake to control wheel slip. In vehicles equipped with ASR, the mechanical connection between the accelerator pedal and the throttle of the gasoline engine is replaced by an electronic throttle control device.
