A vehicle authentication system for authenticating a portable ID transmitter with respect to an authentication arrangement of a vehicle in order to release vehicle functions for an operator, includes a portable ID transmitter that has at least one ID transmitter-UWB-antenna. The authentication device has at least one first vehicle-UWB-interface having one first UWB antenna and a second vehicle-UWB interface with a second UWB-antenna. Control for the authentication device are also provided so that an authentication method can be carried out. Optionally, the authentication system can also include LF interfaces with LF antennas and proximity sensors.

Method for operating authentication system and authentication system

Method for activating at least one function of a vehicle, a mobile communication device being provided for communication, characterized by the following steps: monitoring the communication, wherein at least one evaluation signal specific for the communication is determined, detecting a vehicle influence on a transmission during communication using an evaluation of the evaluation signal in order to perform a localization of the communication device and activating the function of the vehicle depending on the detection of the vehicle influence.

Method for activating at least one function of a vehicle

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

Method for activation of at least one security function of a security system of a vehicle

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

Method for activating at least one security function of a security system of a vehicle

The invention relates to a method () for activating at least one security function of a security system () of a vehicle (). 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 () to the vehicle () by means of a detection device () of the vehicle () and a transmission of the distance information by a data transmission from the detection device () via a transmission system () of the vehicle () to a processing device () of the vehicle (), wherein the data transmission of the distance information is performed in a forgery-proof manner.

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.

Method for controlling access to a motor vehicle

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.
