Abstract

A motor vehicle door lock system with a vehicle lock, which can be locked and unlocked by a motor, includes a lock element which can be moved between a locked position and an unlocked position, and a central interlock drive with a slow-running drive element with which the lock element can be moved, with control electronics with a passive entry function, a speed unlocking element and a remote control module for the operator. The motor vehicle door lock system includes a clutch which engages only with a minimum rpm, which ensures that the lock element can be easily moved by hand with the central interlock drive stationary. The speed unlocking element is assigned to the central interlock drive on this side of the clutch and can be immediately actuated by the central interlock drive upon starting. The speed unlocking element immediately moves the lock element or an element of the lock mechanism downstream of it, the central interlock drive follows up, with the clutch engaged, more slowly into the unlocked position or via the unlocked position in to the next rest position when actuated out of the locked position into the unlocked position.
