What does the accelerator pedal of new energy vehicles control?

The pedal position sensor transmits the detected signal to ECU through cable. After analysis and judgment, ECU sends an instruction to the driving motor, which controls the opening of throttle valve to adjust the flow of combustible mixture. Under heavy load, the throttle opening is large, and a large amount of combustible mixture enters the cylinder. If you use the cable throttle, you can only control the throttle opening by stepping on the pedal with your foot.

It is difficult to adjust the throttle opening to reach the theoretical air-fuel ratio, but the electronic throttle can analyze and compare all kinds of data collected by sensors through ECU, send out instructions to make the throttle actuator act and adjust the throttle to the optimal position, so as to reach the theoretical air-fuel ratio 14.7: 1 under different loads and working conditions, and make the fuel burn fully.

The electronic throttle controls the opening of the throttle through cables or wire harnesses. On the surface, the traditional throttle cable is replaced by a cable, but in essence, it is not only a simple change in connection mode, but an automatic control function for the power output of the whole vehicle.
