Working principle of six-wire accelerator pedal

The key of accelerator pedal is to adjust the accelerator opening of automobile engine, and then control the energy output of diesel engine. With the development trend of automotive electronic technology, the application of electronic accelerator pedal is becoming more and more common. Nowadays, vehicles are basically electronic accelerator pedals. The accelerator pedal has five lines and six lines, but six lines account for the majority. Two sensors are embedded in the six-wire accelerator pedal, and the six wires are two power supply system wires, two power supply wires and two ground wires respectively.

Principle of six-wire accelerator pedal

The basic principle of electronic accelerator pedal electrical equipment According to the type of pedal phase sensor, electronic accelerator pedal can be divided into two categories: non-contact and non-contact. At present, the most widely used electronic accelerator pedal is a non-contact programmable controller based on Hall effect, and its electronic accelerator pedal angular displacement sensor is installed at the accelerator pedal to detect the position of the accelerator pedal.

When it is detected that the height-width ratio of the accelerator pedal changes, the information will be converted into working voltage and transmitted to ECU, which will calculate the information and data information of other system software to calculate the optimal opening of the throttle valve, and send it to the servo motor electronic accelerator pedal motor automobile relay according to the route, and the servo motor motor will push the throttle valve to perform the corresponding posture.

How to accurately measure line 6 of accelerator pedal

1, according to the video decoder, get the data stream to see if there is a fault code;

2. Check the working voltage of sensor line 6 with a multimeter to see if it will change with the accelerator pedal.
