Is the electronic throttle an electronic throttle?

Electronic throttle is not a traditional throttle, but an electronic control device that realizes the function of throttle. Electronic throttle is one of the important control parts of engine, which consists of engine, speed sensor and throttle. It can effectively control the throttle opening, reduce fuel consumption, reduce emissions and improve driving maneuverability. The electronic throttle replaces the cable and joystick of the traditional throttle with wires, and the opening of the throttle is driven by a micro motor. The electronic throttle control system can not only accurately control the throttle opening, but also integrate many functions such as idle speed control, cruise control and vehicle stability control, which simplifies the structure of the control system. The specific working principle is that the driver operates the accelerator pedal to generate a corresponding voltage signal, which is input to the accelerator control unit. Firstly, the control unit filters the signal to reduce noise, analyzes the driver's intention and calculates the torque required by the engine, and then obtains the corresponding expected throttle angle. The control unit will also communicate with the vehicle control unit through CAN bus, obtain various sensor signals, calculate the torque required by the vehicle, and use the throttle position sensor for closed-loop position control, and finally realize the accurate control of the throttle opening.
