PARKING LOCK ACTUATION SYSTEM WITH ELECTROMECHANICAL LOCKING FUNCTION, DRIVE DEVICE, AND ACTUATION METHOD

A parking lock actuation system for a motor vehicle includes an actuation element that can be moved between a locking position, in which a parking lock of the motor vehicle is active, and an unlocking position, in which the parking lock is inactive. The system also includes a locking element which is designed to fix the actuation element in the unlocking position in a form-fitting manner; and an electric actuator which has an adjusting effect on the locking element. A current circuit which has an autonomous power source is connected to the electric actuator, and a bistable switch and a monostable opener arranged in series to the bistable switch are used in the current circuit.
