Method for actuating a parking lock device

Abstract

A method for actuating a parking lock device having a locking element that can be moved depending on an actuation position of an actuation element in order to set a parking position of a vehicle. A hydraulic device includes a first valve, which can be switched at least between a first valve state and a second valve state in order to change the actuation position via a system pressure. The valve state of the first valve is checked by first initiating a switch between the first and second valve state in a switching step, and then a detection step is carried out in which the system pressure is increased in a pressure increase step, and in an ascertaining step a movement of the actuation element is detected and the valve state of the first valve after the switching step is inferred on the basis of the detected movement.

Dependencies are inferred from the claim text.
