Abstract

A motor vehicle is described which has an engine and an automatically shifted transmission. As an operating element, the transmission has at least one selecting device by which a driver controls an electric transmission control device. As a function of a driving position selected on the selecting device and of other operating parameters of the motor vehicle, the electric transmission control device controls a parking position function of the automatic transmission among other functions. In this case, the parking position will be engaged in the automatically shifted transmission when the driving speed of the motor vehicle is equal to zero and simultaneously the ignition circuit was interrupted by the ignition key and after a predetermined time period has elapsed or when a vehicle door is opened. Alternatively, the parking position is engaged or no later than when the ignition key is removed from the ignition lock.
