1. A system comprising:
- a vehicle-external induction charging unit comprising a primary coil and a low-frequency receiving antenna; and
a vehicle comprising;
a secondary coil configured for inductive charging of the vehicle at the induction charging unit via the primary coil,an automatic radio-based vehicle safety unit having at least two low-frequency transmitting antennas, andan access control device configured to;
detect the spatial position of an access element relative to the vehicle based on the principle of electromagnetic distance and angle measuring between the transmitting antennas and a low-frequency receiver of the access element, anddetect the location position of the induction charging unit relative to the vehicle based on the principle of electromagnetic distance and angle measuring between the transmitting antennas and the receiving antenna,wherein the access element is wirelessly coupled to the vehicle safety unit and is configured to permit user access to the vehicle when in the vicinity of the vehicle.

Abstract
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.
