Accelerator pedal module

The position of the accelerator pedal is reported to the DME/DDE control unit via analog voltage signals. The signals are generated by two pedal sensors in the accelerator pedal module.

The pedal sensors take their 5 V power supply and ground connection from the DME/DDE control unit. Depending on the operating angle, the pedal sensors return various voltages to the DME/DDE control unit. The DME/DDE control unit converts the voltage signals into the pedal sensor position.

The signal of pedal sensor 2 always has half the signal voltage of pedal sensor 1.

The idle, full load and kickdown positions are detected by way of voltages of the pedal sensors.

Fault handling 

The pedal sensors are monitored for short circuit and open circuit, as well as for plausibility in relation to one another.
