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 door lock and a process for controlling a motor vehicle door lock, the motor vehicle door lock having an electric motor drive for reaching a set position based upon at least one operating parameter such as a start-up characteristic acquired when the drive is started up. The electric motor drive is shut off and short circuited prior to the set position in time and in position. In order to achieve high positioning accuracy, deviations from the set positions are acquired to correct the shut-off point for later positioning.

Abstract: An apparatus for folding down back seats in a motor vehicle in order to enlarge the cargo volume, having individual seat elements that can be moved in relation to one another, wherein at least one seat element or a part of a seat element can constitute a part of a loading surface (10), and having drive mechanisms (12, 14, 16) which are connected to the individual seat elements. The proposal is made that a first drive mechanism (12) be disposed at a rotation point (18) of a seat bottom (20), a second drive mechanism (14) be disposed at a sliding point (22) of a headrest (24), and a third drive mechanism (16) be disposed at a rotation point (26) of a seatback (28).

Abstract: An electronically commutable motor, whose excitation windings can be fed with current via semiconductor output stages from an electronic control unit using pulse-width modulated control signals and, in this context, which generate a rotating field in the stator of the motor, the rotating field placing the permanent magnet of the motor in rotational motion.

Abstract: An electrically controllable motor vehicle door lock, a motor vehicle door lock system with such a motor vehicle door lock, and a process for controlling the motor vehicle door lock. Simple and optimum adjustability of the functionality of the motor vehicle door lock is enabled by storing control parameters which determine the functionality of the motor vehicle door lock in an electrical storage. The control parameters are adaptable and can be changed so that the functionality of the motor vehicle door lock is fixed by its control parameters. Moreover, different control parameters or sets of control parameters can be used for different functioning states or closing states of the motor vehicle door lock, and therefore, the conditions for the passage from one state into another state of the motor vehicle door lock can be fixed regardless of which states or combination possibilities occur.
