Abstract
A shift by wire system for a motor vehicle, having a transmission control device and an actuation assembly, operationally connected thereto via an electrical connection. The actuation assembly is designed to generate a signal relating to an intention of the driver, corresponding to a position of the gearshift lever, by means of a gearshift lever and at least one sensor. The actuation assembly also has a controller unit, by means of which data based on the signal is communicated to the transmission control device via the electrical connection. The transmission control device monitors, in a remote manner, the controller unit in the actuation assembly via the electrical connection. The electrical connection is both a communication line for the data based on the signal and for the remote monitoring.
