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.
