Motor vehicle door lock system
First Claim
1. Motor vehicle door lock system (2) with a motor vehicle door lock (3), an outside door handle (10) which is assigned to the motor vehicle door lock (3), which is made stationary, and which has no moving parts, and a sensor (12) assigned to the outside door handle (10) for detection of touching and/or actuation of the outside door handle (10) by the hand of the operator, and when the outside door handle (10) is touched or actuated a first signal (A) and when released a second signal (B) can be produced and output by the sensor (12) and the two signals (A, B) can be evaluated as the start and end of actuation of the outside door handle (10), and/or a pressure load (20) which acts on the outside door handle (10), at least in the area of one section (21) of the outside door handle (10), can be detected and can be evaluated as a locking signal (D).

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.

32. Process for controlling a motor vehicle door lock system (2) with a motor vehicle door lock (3) and a stationary outside door handle (10) which is assigned to the motor vehicle door lock (3),
touching and/or actuation of the outside door handle (10) by the hand of an operator being detected by means of a sensor (12) which is assigned to the outside door handle (10), when the outside door handle (10) is touched or actuated a first signal (A) and when the outside door handle (10) is released a second signal (B) being produced by the sensor (12) and the two signals (A, B) being evaluated as the start and end of actuation of the outside door handle (10), the sensor (12) converting changes of force and/or pressure into electrical signals or changes of at least one electrical characteristic, and the first signal (A) and the second signal (B) being detected by evaluation of the time response and/or time derivation of the sensor signals, when the first signal (A) is detected the motor vehicle door lock (3) being opened by a motor until the second signal (B) is detected and/or the first signal (A) being detected with a tensile load (19) on the outside door handle (10) and when the second signal (B) occurs before the first signal (A) a pressure load (20) acting on the outside door handle (10), at least in the area of one section (21) of the outside door handle (10), being detected and this being evaluated or used as a locking signal (D) for locking the motor vehicle door lock (3).
