Establishing a charging communication between charging station and vehicle
First Claim
1. A method for establishing a wireless communication connection between a vehicle communication unit of a vehicle and a charging station communication unit of a charging station, the method comprising the acts of:
- emitting respective low-frequency (LF) request signals via a plurality of LF transmitting units of the vehicle, wherein the LF request signals indicate an identifier with respect to the vehicle and wherein the LF request signals comprise a request signal of a keyless access function and/or of a keyless engine starting function of the vehicle;
receiving the LF request signals by an LF receiving unit of the charging station, wherein the LF receiving unit is constructed like a receiving unit of a vehicle key with a keyless access function and/or a keyless engine starting function;
emitting items of information with respect to the identifier in a broadcast message by the charging station communication unit, wherein the broadcast message by the charging station communication unit further comprises items of information with respect to respective signal strengths with which the LF request signals were received by the charging station communication unit; and
receiving the broadcast message by the vehicle communication unit;
checking whether the broadcast message comprises the items of information with respect to the identifier; and
establishing a wireless communication connection between the vehicle communication unit and the charging station communication unit if the broadcast message comprises the items of information with respect to the identifier.

Abstract
A method establishes a wireless communication connection between a vehicle communication unit of a vehicle and a charging station communication unit of a charging station. The method includes the transmission of a low-frequency signal via a LF transmission unit of the vehicle, wherein the LF request signal displays an identifier relating to the vehicle. The method also includes the receiving of the LF request signal via an LF receiving unit of the charging station. The method further includes the transmission of information relating to the identifier in a broadcast message via the charging station communication unit, as well as the receiving of the broadcast message via the vehicle communication unit. In addition, the method includes the checking of whether the broadcast message comprises the information relating to the identifier, and the establishing of a wireless communication connection between the vehicle communication unit and the charging station communication unit, if the broadcast message comprises the information relating to the identifier.

9. A charging station for charging an electrical energy store of a vehicle, comprising:
-
a low-frequency (LF) receiving unit, which is configured to receive respective low-frequency request signals from a plurality of LF transmitting units of a vehicle in a vicinity of the charging station, wherein the LF request signals indicate an identifier with respect to the vehicle and wherein the LF request signals comprise a request signal of a keyless access function and/or of a keyless engine starting function of the vehicle, and wherein the LF receiving unit is constructed like a receiving unit of a vehicle key with a keyless access function and/or a keyless engine starting function; and a charging station communication unit, which is configured to emit items of information with respect to the identifier in a broadcast message, wherein the broadcast message further comprises items of information with respect to respective signal strengths with which the LF request signals were received by the LF receiving unit, and in response to a request by a vehicle communication unit of the vehicle to establish a wireless communication connection between the vehicle communication unit and the charging station communication unit.

10. A vehicle, comprising:
-
a plurality of low-frequency (LF) transmitting units, which are configured to emit respective LF request signals, wherein the LF request signals indicate an identifier with respect to the vehicle and wherein the LF request signals comprise a request signal of a keyless access function and/or of a keyless engine starting function of the vehicle; and a vehicle communication unit, which is configured to; receive a broadcast message from a charging station communication unit of a charging station, wherein the charging station includes an LF receiving unit which is configured to receive the LF request signals and wherein the LF receiving unit is constructed like a receiving unit of a vehicle key with a keyless access function and/or a keyless engine starting function; check whether the broadcast message comprises items of information with respect to the identifier, wherein the broadcast message further comprises items of information with respect to respective signal strengths with which the LF request signals were received by the charging station communication unit; and initiate the establishing of a wireless communication connection between the vehicle communication unit and the charging station communication unit if the broadcast message comprises items of information with respect to the identifier.
