ABSTRACT:
A method of automatically engaging a parking lock or an automatic or automated gearbox of a motor vehicle, which can be engaged depending on a drive position selected by the driver of the motor vehicle, by way of a selector device and depending on other operating parameters. In order to achieve as little restriction of the drivability of the motor vehicle as possible, without neglecting the safety of the driver and surroundings, two different complex embodiments of an Auto_P function for automatically engaging the parking lock are proposed, if the motor vehicle is at least approximately stopped and, at the same time, an ignition circuit acting on the drive motor of the motor vehicle is electrically interrupted.
