Motor vehicle swing door arrangement
A motor arrangement with a door which can be swung between a closed and open position, including a door locking arrangement having an electrically actuated door latch configured to be moved between a locked and unlocked position, and a push-open arrangement for pushing open the door body from its closed position. The push-open arrangement includes a plunger, an actuator driving the plunger, and a controller configured to unlock the door locking arrangement when an electronic opening request is received and then electrically supply the actuator in a normal mode, such that the swing door is pushed from its closed to open position. The controller is configured to switch to a crash mode and to supply the actuator with an electrical power which is increased by at least 50% compared to the normal power when an opening request is received.
