What is the working principle of six-wire accelerator pedal?

The working principle of the six-line accelerator pedal of Pacific Auto Network is that the position sensor transmits the signal of the depth and speed of the accelerator pedal, and the signal will be received and interpreted by the on-board microcomputer, and then a control command will be issued, requiring the accelerator to open the angle it should open quickly or gently according to the command.

Electronic throttle control system is mainly composed of accelerator pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor and throttle actuator. When it is detected that the height position of the accelerator pedal changes, the information will be sent to ECU immediately. The ECU will calculate and process information and data information from other systems to calculate a control signal, which will be sent to the servo motor relay through the line. The data bus is responsible for the communication between the system ECU and other ecus.

The six wires of the six-wire accelerator pedal are two signal wires, and two potentiometers are used for power supply and grounding respectively. When the accelerator pedal is depressed, the potentiometer signals rise and fall one after another. When the computer receives this signal, it controls the throttle motor to rotate at a certain angle to meet the air intake under various working conditions. If the signals go up one by one, but not down, the computer judges that there is something wrong with the accelerator pedal sensor and lights the EPC light.
