What is the principle of electronic throttle?

The principle of electronic throttle is as follows: 1, the driver manipulates the accelerator pedal, and the accelerator pedal position sensor generates the corresponding voltage signal and inputs it into the accelerator control unit; 2. The control unit calculates the required torque and throttle angle, and sends corresponding voltage signals to the drive circuit module; 3. Drive the control motor to make the throttle valve reach a better opening position; 4. The throttle position sensor feeds back the throttle opening signal to the throttle control unit to form closed-loop position control. The electronic throttle system consists of: 1, engine; 2. Speed sensor; 3. Throttle position sensor; 4. Throttle actuator; 5. throttling; 6. Accelerator pedal position sensor; 7. Speed sensor; 8. transmission; 9. accelerator pedal; 10, throttle electronic control unit.
