A system includes a vehicle having an automatic radio-based vehicle safety unit and an access control device. An access element is assigned to the vehicle safety unit, where the vehicle safety unit has several low-frequency transmitting antennas, and the access element has a low-frequency receiver. By means of the access control device, the spatial position of the access element relative to the vehicle is detectable based on the principle of electromagnetic distance and angle measuring between the transmitting antennas and the receiver. The system further includes a vehicle-external induction charging unit having a primary coil, and the vehicle comprises a secondary coil for the inductive charging of the vehicle at the induction charging unit, where the induction charging unit has at least one low-frequency receiving antenna. The access control device is configured to can carry out a detection of the location position of the induction charging unit relative to the vehicle based on the principle of electromagnetic distance and angle measuring between at least two transmitting antennas of several low-frequency transmitting antennas and the at least one receiving antenna.
