In fact, the throttle opening is controlled by the motor, and the throttle pull line between the throttle pedal and the throttle is canceled. In other words, the driver's intention to accelerate will be transmitted to the engine controller through the position sensor of the accelerator pedal, and the engine controller will adjust the throttle body through the motor.
At the same time, the electronic throttle opening sensor will feedback the detected opening signal to the ECU to realize the closed-loop control of the electronic throttle opening.
