What is the sensor in the pedal of BMW's new x 1 door?
Brief introduction of BMW's new x 1 door pedal sensor;
The sensor is an important part of the electronic accelerator system, and the electronic accelerator passes through the position of the electronic accelerator pedal.
The sensor transmits the signal of the depth and speed of the accelerator pedal, which will be received and interpreted by the ECU, and then sends out a control command to open the throttle quickly or gently according to the command. ?
The electronic accelerator system is mainly realized by accelerator pedal, electronic accelerator pedal position, ECU, data bus, servo motor and accelerator.

Working principle of sensors in BMW's new x 1 door pedal;
The working principle of potentiometer accelerator pedal position sensor is voltage dividing circuit, and ECU provides 5V voltage to the sensor circuit.
The electronic accelerator pedal is connected with the brush of the sliding rheostat inside the sensor through the rotating shaft. When the position of the accelerator pedal position sensor changes, the voltage between the brush and the ground terminal changes, and the ECU converts the voltage into the position signal of the accelerator pedal.
The accelerator pedal position sensor outputs two sets of signals to ECU at the same time to ensure the reliability of the output signals.
