Abstract
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.
Claims20
A parking lock actuation system for a motor vehicle, the parking lock actuation system comprising:
- an actuation element moveable 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;
- a locking element configured to fix the actuation element in the unlocking position in a form-fitting manner;
- an electric actuator which has an adjusting effect on the locking element;
- and
- a current circuit having an autonomous power source, the current circuit being connected to the electric actuator, a bistable switch and a monostable opener arranged in series with the bistable switch being used in the current circuit.
A parking lock actuation system for a motor vehicle, the parking lock actuation system comprising:
- an actuation element movable 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;
- a locking element configured to engage the actuation element in a form-fitting manner to fix the actuation element in the unlocking position;
- an electric actuator configured for adjusting the locking element;
- and
- a current circuit having an autonomous power source, the current circuit being connected to the electric actuator, the current circuit including a bistable switch and a monostable opener arranged in series with the bistable switch, the locking element being engagable in the form-fitting manner with the actuation element when the current circuit is interrupted, the electric actuator configured for breaking a form fit engagement between the locking element and the actuation element when the current circuit is closed.
