How is the signal of automobile accelerator pedal transmitted to ECU, and how does ECU control the accelerator? Find the specific analog signal and logic gate circuit, thank you.

Pedal signal: there are one or two channels, and generally two channels are used. The pedal output signal is a voltage signal. The ecu collects the signal and knows the pedal position.

Throttle control: ecu can only control electronic throttle. There is a throttle position sensor in the throttle, which is also a voltage signal. Ecu knows the throttle position by collecting this signal and controls the throttle motor to drive the throttle to the corresponding position, which is a closed-loop control.

The control target of throttle position is determined by pedal signal, engine state, vehicle speed and other input parameters through torque model operation in ecu.

With all due respect, you can't find the circuit in this way, and it's of little use if you find it. The main control is software.
