What is the working principle of the electronic throttle?

The working principle of the electronic throttle is: the driver manipulates the accelerator pedal accelerator pedal position sensor generates the corresponding voltage signal input throttle control unit control unit calculates the demand torque, throttle angle and will be the corresponding voltage signal sent to the drive circuit module to drive the control motor so that the throttle valve to achieve a better opening position throttle position sensor to the throttle valve opening signal feedback to the throttle valve The throttle position sensor feeds the throttle opening signal back to the throttle control unit to form a closed-loop position control. Electronic throttle system is composed of: 1, engine; 2, speed sensor; 3, throttle position sensor; 4, throttle actuator; 5, throttle; 6, accelerator pedal position sensor; 7, speed sensor; 8, transmission; 9, accelerator pedal; 10, throttle electronic control unit.
