Abstract: An auxiliary locking drive for a motor vehicle lock having its own drive housing and being located separate from the vehicle lock in the installed state. The auxiliary locking drive can be coupled to the vehicle lock by way of a transmission that transmits a linear driving motion produced by a drive motor to the vehicle lock for transferring the vehicle lock from the half-locked state into the main locked state by the driving motion. The auxiliary locking drive, for producing the linear driving motion, has a feed gear mechanism which is connected downstream of the drive motor and is made as a spindle-spindle nut gearing with a spindle and a spindle nut.

Abstract: A motor vehicle door lock system with at least one vehicle lock, an outside door handle assigned to the vehicle lock, and at least one sensor assigned to the outside door handle, where the system is adapted to detect the approach of the hand of an operator to the outside door handle and/or touching and/or activating of the outside door handle. In one embodiment of motor vehicle door lock system, the activation of the outside handle by the hand of an operator or the approach to the outside door handle is recognized early. A vibration generator is assigned to the outside door handle such that the outside door handle or a part thereof is mechanically vibrated. A sensor is provided for acquiring the vibration, the sound waves caused by the vibration and/or their reflections so that the motor vehicle door lock system can detect when the outside door handle or a part thereof is being approached and/or touched and/or activated by the hand of an operator.

Abstract: A motor vehicle hatch lock or the like, with a latch which is pivotable around an axis, with a ratchet which is pivotable around another axis, and with an actuator, the actuator having an actuating element with the engagement element located thereon. By actuating the actuator out of the initial position in a first direction the ratchet is raised by the actuating element for an opening assistance function, and by actuating the actuator out of the initial position in a second direction opposite the first direction, the actuating element is coupled to the latch and the latch is moved from the pre-catch position into the main catch position for a closing assistance function with the actuating element being coupled to the latch by a step-down gear.
