  • Patent number: 11976725
    Abstract: An electromechanical parking lock for a motor vehicle includes a locking element for reversible engagement in a parking lock wheel, an actuating element that can be pre-loaded by an actuating spring in order to insert the locking element into the parking lock wheel, an electric motor with an actuating unit for moving the actuating element out of the locked position (P) against the spring force of the actuating spring into an unlocked position (nP), and a solenoid that, in the unlocked position (nP), holds the actuating element pre-loaded via a securing element. The parking lock has an emergency locking position (Not-P) in which the parking lock is unlocked and in which the securing element can be released by the electric motor without changing the state of the solenoid so that the locked position (P) can be assumed.
