Abstract

Apparatus for determining the position of a mobile access device relative to a motor vehicle includes a control device in the vehicle which disables and enables access to a vehicle function. A plurality of separate modules each include a housing, a communication device for wireless short-range communication and an energy store. The modules have a mounting attachment in the interior of a vehicle and at least one of the modules is coupled to the control device for the purpose of data transmission. The modules each detect a signal strength of a signal transmission between the access device and the respective module and are configured with the control device to carry out position determination for the access device on the basis of multiple detected signal strengths of different modules and to enable or disable access to the vehicle function on the basis of the determined position.
