Abstract: A method for operating a passive access system for motor vehicles includes arranging multiple transmission antennas at different locations on a motor vehicle for sending out low frequency signals. A mobile ID transponder, formed by a 3D-receiving antenna assembly, receives the low frequency signals. The antennas send out time-delayed first signals and then simultaneously send out signals. A signal strength is detected by the 3D antenna assembly in the ID transponder for each spatial direction. Information related to the space-direction-dependent signal strengths is transmitted from the ID transponder to the motor vehicle. Depending on the received information, the transmission signal strengths are adjusted. Then, further low frequency signals are sent, and received in the ID transponder. Based on further signal strength information, a plausibility check is performed in order to detect an extension of the signal path between the motor vehicle and the ID transponder via intermediate stations.

Abstract: A motor-vehicle door handle includes at least one electronics subassembly and a first sensor electrode for a first capacitive sensor for triggering an unlocking operation when an approach to a grasping area is sensed. The sensor electrode is connected to the electronics subassembly. In known motor-vehicle door handles, the sensor electrode is arranged within the electronics module a) over a large surface area and b) always adjacent to the grasping area. For the instant motor-vehicle door handle there is improved flexibility in respect of position and configuration of the electronics module. This is achieved by the first sensor electrode being, in part, led out of the electronics module, that part of the sensor electrode which is led out having a portion which is arranged adjacent to the grasping area in the motor-vehicle door handle such that an approach to the grasping area can be sensed.
