    摘要: A parking lock assembly for a motor vehicle is described that has at least one electrically drivable driving axle. The parking lock comprises an electric drive, a shaft which is arranged in the driveline of a motor vehicle and which is drivable by the electric drive, as well as a locking mechanism which is controllable in the locking sense in order to prevent a rotational movement of the shaft and which is controllable in the opening sense in order to release the shaft. The electric drive is controllable in order to transmit torque to the shaft if, in spite of the locking mechanism being controlled in the opening sense, the shaft is prevented from carrying out a rotational movement. Furthermore, a method of actuating such a parking lock assembly is described.
