The working principle of the six-wire accelerator pedal, how to measure the six-wire accelerator pedal

The accelerator pedal is mainly used to control the opening of the engine throttle, thereby controlling the power output of the engine. With the continuous development of automotive electronics technology, the application of electronic accelerators has become more and more extensive. Now automobiles are basically electronic accelerator pedals, and accelerator pedals have 5 wires and 6 wires, but most of them are 6 wires. The six-wire accelerator pedal has two built-in sensors. The six-wires are 2 power supply wires, 2 signal wires and 2 ground wires.

The working principle of the six-wire accelerator pedal

The electrical principle of the electronic accelerator pedal is based on the type of the pedal position sensor. The electronic accelerator pedal can be divided into two types: contact type and non-contact type. At present, the most widely used non-contact programmable electronic accelerator pedal based on the Hall effect, the electronic accelerator pedal angular displacement sensor is installed inside the accelerator pedal to monitor the position of the accelerator pedal.

When a change in the height of the accelerator pedal is detected, it will convert this information into voltage and send it to the ECU. The ECU uses this information and other system data to perform calculations to calculate the optimal throttle opening and send it through the line Servo electronic throttle motor relay, servo motor drives the throttle to perform related actions.

Accelerator pedal 6How to measure the line

1. Read the data stream through the decoder to see if there is anyerror codeAppear;

2. Use a multimeter to detect the 6-wire voltage of the sensor to see if it changes with the pedaling of the accelerator.
