Abstract: A motor vehicle door locking system and a process for controlling the locking system. A piezoelement is assigned to a stationary outside door handle and is used to detect touching and/or actuation of the outside door handle. To increase the operating reliability, to simplify troubleshooting and to minimize the power consumption, there is a monitoring device that monitors the piezoelement. The piezoelement is monitored for fracture and the occurrence of the first signal.

Abstract: A motor vehicle door lock with mechanical lock elements in a lock unit, the door lock includes a lock mechanism with several interacting elements in a control unit which is arranged at a location that is spatially separate from the lock unit in or on a motor vehicle door or hatch. The lock unit is connected to the control unit by a remote power transmission in the form of a Bowden cable, and the lock element in the lock unit can be mechanically actuated from an element of the lock mechanism in the control unit by the remote power transmission. In the lock unit, there is at least one component which is to be supplied with electricity to be triggered and/or to be interrogated, the at least one component is electrically connected by an electrical connecting element to lock electronics in the control unit, and the electrical connecting element is integrated into or combined with the mechanical power transmission.

Abstract: A motor vehicle door lock system, an outside door handle arrangement, and a process for controlling a motor vehicle door lock system are proposed. For simple, economical sensing of the actuation of an outside door handle, a first signal is detected when the outside door handle is touched, and when the outside door handle is released a second signal is detected, the signals being evaluated as the start and end of actuation of the outside door handle. Alternatively or in addition, it is provided that a pressure load on the outside door handle is detected for locking the assigned motor vehicle door lock.

Abstract: An outside door handle arrangement and a process for controlling a motor vehicle door lock system are proposed. For simple, economically feasible detection of the actuation of an outside door handle, it is provided that the outside door handle is elastically deformable and deformation is detected by a sensor to acquire actuation.

Abstract: An outside door handle arrangement including an electronic sensor for detecting actuation of an outside door handle of a motor vehicle. An electronic circuit, which is assigned to the electronic sensor, is located directly on a piezoelement such that the piezoelement is used as a circuit carrier. Additionally, the piezoelement is used for holding an assigned electronic circuit such that the electronic circuit is mounted on and is electronically connected to the piezoelement.
