What is the working principle of electronic throttle?

The working principle of electronic throttle is that the driver controls the accelerator pedal position sensor to generate corresponding voltage signals, which are input into the throttle control unit to calculate the required torque and throttle angle, and the corresponding voltage signals are sent to the drive circuit module to drive the control motor to make the throttle reach a better open position. 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.
