ASR of Electronic Throttle Control System

The traction control system is also called drive anti-skid system. Its function is to control the slip rate in a certain range when the car accelerates, so as to prevent the driving wheel from sliding rapidly. Its function is to improve the traction force and to maintain the driving stability of the car. It reduces engine power by reducing throttle opening to achieve control purposes. 
The principle is as follows: The control unit collects the acceleration pedal position, wheel speed and steering angle signals, calculates the slip rate, generates the corresponding control voltage signal, and transmits the signal to the control unit through the data bus. According to this signal, the control unit will reduce the throttle opening to adjust the mixed air flow, so as to reduce the engine power. At this time, the control signal of the control unit to the throttle will not be affected by the driver's driving intention, so that the driver's misoperation can be avoided. According to the current speed, throttle opening and engine speed signals, it should choose the appropriate transmission ratio for the control unit to achieve automatic shift. The electronic throttle control system eliminates idle control valves, and controls the throttle opening directly by the control unit to achieve idle control of the vehicle.
