Abstract: The invention relates to a method (100) for a security system (200) of a vehicle (1), in particular for a keyless activation of at least one security function of the vehicle (1).

Abstract: The invention relates to a method (100) for an activation of at least one security function of a security system (200) of a vehicle (1), wherein an authentication at the security system (200) of the vehicle (1) is effected by means of a mobile identification transmitter (300).

Abstract: The invention relates to a method (100) for activating at least one security function of a security system (200) of a vehicle (1). According to the invention, provision is made for the detection of at least one distance information about a distance (A) of a mobile identification transmitter (300) to the vehicle (1) by means of a detection device (10) of the vehicle (1) and a transmission of the distance information by a data transmission from the detection device (10) via a transmission system (50) of the vehicle (1) to a processing device (60) of the vehicle (1), wherein the data transmission of the distance information is performed in a forgery-proof manner.

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.
