Abstract
A motor vehicle door lock system including a vehicle lock adapted to be locked and unlocked, a lock element adapted to be moved between a locked position and an unlocked position for locking and unlocking respectively the vehicle lock, a central interlock drive having a slow running drive element for moving the lock element, a remote control module, control electronics with a passive entry function to at least passively unlock the vehicle lock, and a high-speed electromagnetic drive for rapidly moving the lock element from the locked position to the unlocked position to thereby unlock the vehicle lock quicker than by operating the drive element. The passive unlocking of the vehicle lock occurs over time requiring a reaction phase with a starting interval, an authorization check interval, and an action interval, the starting interval being initiated by an operator. The high-speed electromagnetic drive is immediately activated at start of the action interval, and subsequent to the activation, the central interlock drive is operated to move the slow running drive element to a position corresponding to the unlocked position of the lock element.
