CAN CAN data bus (Controller Area Network)

A modified characteristic curve of the electronic accelerator (EFP) optimizes ride comfort and safety while reversing.

The reversing action (drive position "R") is indicated by the ETC [EGS] control unit to the motor electronics control unit via the CAN data bus. The ME control unit then uses an altered characteristic to regulate the throttle valve actuator.
Here the throttle valve is opened slowly and the opening angle is limited to maximum 60%.
