Abstract
A parking lock actuation system for a motor vehicle includes an actuation element that is coupled or can be coupled to a parking lock and can be moved between a locking position, in which the parking lock is active, and an unlocking position, in which the parking lock is inactive. The system includes a locking element which is designed to fix the actuation element in the unlocking position in a form-fitting manner. The actuation element and the locking element () are each operatively connected to a respective hydraulic actuation cylinder, and the two hydraulic actuation cylinders are connected to a common hydraulic fluid supply line by a pressure chamber and are coupled to a pump via a first valve. The actuation cylinder of the locking element additionally has an unlocking pressure chamber which counteracts the actuation cylinder pressure chamber and which can be coupled to the pump via a second valve.
