Fault phenomenon of accelerator pedal sensor
Manifestation of accelerator pedal sensor failure:
1. The electronic accelerator pedal is applied to the electronic accelerator control system. Its principle is to convert the throttle demand signal into a voltage signal through the pedal position sensor and send it to ECU. ECU calculates the optimal throttle opening by integrating current vehicle speed, vehicle distance, throttle opening and engine speed. ECU controls the output torque of DC motor and constantly adjusts the opening of electronic throttle. The throttle position sensor feeds back the throttle position signal to ECU to form closed-loop control, and finally stabilizes the electronic throttle at the optimal opening.
2. The accelerator pedal sensor is installed in the accelerator pedal to monitor the position of the pedal. When the accelerator pedal sensor detects the change of the height position of the accelerator pedal, it will send the information to the ECU, which will calculate and process the information and data information from other systems to calculate a control signal, which will be sent to the servo motor relay through the line, and the servo motor will drive the accelerator actuator;
3. If the accelerator pedal sensor fails,
