A method for determining an occupied region of a first radio device is provided. According to the method, a signal is transmitted from the first radio device and received by at least two additional radio devices. Based on a propagation time of the signal from the first radio device to the additional radio devices, a surrounding region is determined around each of the additional radio devices in which the first radio device is located. The occupied region of the first radio device is determined based on an overlapping region which results from an overlapping of all surrounding regions. Alternatively, signals can also be transmitted from the additional radio devices and received by the first radio device. The method can be used to determine whether an automobile key having a radio transmitter is located in a vehicle.

A method and system controls access to an authentication-dependent or authentication-conditional function of a vehicle, via a smart device or smartphone. For the authentication, an authentication feature of the smart device is compared with a stored authentication feature of the device, and authentication is granted if they are identical or sufficiently correspond, the authentication is subjected to an approval process by a user of the smart device, in which it is determined whether the user approves the authentication or not. The authentication and the approval process have at least one channel in a protected region of the smart device and/or are themselves embedded in the protected region, which lies outside a region of the operating system of the applications and/or the apps of the smart device. The function of the device is executed when there is an authentication and an approval.

A method for determining a location area of a mobile terminal relative to a vehicle includes generating a set of positions relative to the vehicle, calculating a location probability of the mobile terminal for one position from the set of positions, and assigning one position from the set of positions to a zone from a plurality of zones of the vehicle. The method also includes determining an aggregated location probability of the mobile terminal for the zone from the plurality of zones depending on the positions assigned to the zone. And, if the aggregated location probability of the mobile terminal for the zone exceeds a predefined confidence value, the method further comprises determining the zone as the location area of the mobile terminal.

The disclosure relates to distance determining apparatus for determining a distance between an anchor and a tag. The apparatus is configured to select a first frame type or a second frame type for a message that is to be transmitted, to optimize an energy of the first frame type for a secure preamble detection, and to optimize an energy of the second frame type for a data transmission.

Apparatus for determining a distance between an anchor and a tag

The disclosure relates to an approximate determination of a distance between a wireless key which is assigned to a motor vehicle and a transceiver arrangement which is disposed in or on the motor vehicle. In the course of a ranging cycle, a first first path relating to a first threshold value and a second first path relating to a higher, second threshold value are calculated. Two distances are estimated on the basis of this dual first path calculation.
