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.
