An access control device of a vehicle is configured to detect the spatial position of the access element of the vehicle safety unit relative to the vehicle via electromagnetically detecting the distances and angles between several low-frequency transmitting antennas of the vehicle safety unit and the low-frequency receiver of the access element. The access control device is also configured to detect the location position of an external induction charging unit relative to the vehicle via electromagnetically measuring the distance and angle between at least two transmitting antennas of several low-frequency transmitting antennas and at least one receiving antenna of the induction charging unit.

Disclosed are systems, methods and devices for measuring a range between wireless devices using an exchange of messages between devices. For example, wireless transceiver devices may exchange messages transmitted in a wireless communications link to measure a time of flight. Based, at least in part, on the measured time of flight, a location of one of the wireless transceiver devices may be estimated.

A method for virtual navigation and communication radios in a vehicle is provided. The method includes receiving a request for a selected radio function, determining a position of a vehicle, determining the data to provide for the selected radio function based on the vehicle position, receiving or generating the data for the selected radio function, and providing the received or generated data over an interface associated with the navigation or communication radio.
