Abstract:
A device and a method for opening and closing a motor vehicle door having a door lock. The device includes an electric opening actuator and an electric closing actuator, by means of which the door lock can be brought from a pre-locking position into a final-locking position. A control device controls the opening and closing actuators. The control device, in the event of a door opening request during operation of the closing actuator, first switches the closing actuator into a reversing mode, in which the door lock can be moved again in the opening direction and the opening actuator is triggered after a predetermined period of time.
