Embodiment Construction

[0034] In the figures, the same reference numerals describe the same technical features. Vehicles with electrified powertrains can be charged wirelessly on inductive charging stations. A vehicle ( 1 ) with an electrified drive train is shown schematically in an embodiment. In this case, the vehicle can be a hybrid vehicle or an electric vehicle, possibly also a plug-in hybrid vehicle, if it also has a charging interface for inductive charging in addition to an interface for wired charging. The vehicle comprises a vehicle-side charging structure for wireless inductive charging, wherein the charging structure has a secondary coil (2) as a central vehicle-side component.

[0035] Additionally, the vehicle includes a radio-based locking system having an access controller (22). The radio-based locking system includes at least two low frequency antennas (5, 6) drivable by the access controller. Additionally, the radio-based locking system includes a radio key (30), which may be l...

Abstract

Disclosed is a system comprising a vehicle (1) which has an automatic, radio-based vehicle security unit (100) and an access control device (102), and comprising an access element (101) that is assigned to the vehicle security unit, the vehicle security unit having a plurality of low-frequency transmission antennae, and the access element having a low-frequency receiver, and the spatial position of the access element relative to the vehicle being determinable by the access control element using the principle of electromagnetic distance and angle measurement between the transmission antennae and the receiver, the system comprising an extra-vehicular induction charge unit (3) with a primary coil (4), the vehicle comprising a secondary coil (2) for inductively charging the vehicle at the induction charge unit, the induction charge unit having at least one low-frequency receiver antenna, and the position of the induction charge unit relative to the vehicle being determinable by the access control device using the principle of electromagnetic distance and angle measurement between at least two transmission antennae of the plurality of low-frequency transmission antennae and the at least one receiver antenna.

Description

technical field [0001] The invention relates to a system comprising a vehicle with an automatic radio-based vehicle security unit and an access (Zugang) controller, and comprising an access element assigned to the vehicle security unit, wherein the vehicle security unit has multiple A low-frequency transmitting antenna, and the access element has a low-frequency receiver, and the access controller can determine the space of the access element relative to the vehicle by electromagnetically measuring the distance and angle between the transmitting antenna and the receiver. Location. Background technique [0002] According to the prior art, for example according to document EP 0 984 123 A2, automatic radio-based vehicle security units are used for checking or for authenticating access to elements. The access element is usually a radio key, with which the user of a particular vehicle can enter the vehicle without actively using the key assigned to the vehicle. The vehicle secu...
