The electronic accelerator function is integrated and controlled in the motor electronics control unit depending on the driver input and the operating condition, the opening angle of the throttle valve.

The position of the accelerator pedal and the speed at which the position of the accelerator pedal changes are transmitted to the sensor located on the accelerator pedal mechanically.
The Hall sensor in the accelerator pedal sensor sends an appropriate voltage signal to the ME control unit. The ME control unit analyzes the voltage signal and, depending on the performance map, activates the throttle valve actuator.
The opening angle of the throttle valve is altered in the throttle valve actuator in line with the driver input and the operating conditions.
An actual value potentiometer in the throttle valve actuator reports the current position of the throttle valve to the motor electronics control unit.

A second actual value potentiometer in the throttle valve actuator and a second Hall sensor in the accelerator pedal sensor supply a reference value for a plausibility check by the ME control unit.
Any detected faults are stored in the fault memory and can be read out and deleted using STAR DIAGNOSIS.

Additional functions of the electronic accelerator pedal:

^ Idle speed control
^ Cruise control (CC [TPM])
^ Torque reduction
^ Emergency running
^ Data transfer over CAN

Input signals for the electronic accelerator pedal:

^ Accelerator pedal position
^ Brake actuation (via the ESP control unit)
^ Cruise control operation (via the steering column module or the ESP control unit)
^ Reduction of the engine torque (from ESP control unit)
^ Drive position (via the ETC [EGS] control unit)
