    Abstract: A motor includes at least a first and a second antenna, wherein the antennas are arranged spaced apart spatially from one another, by means of a portable identification signal generator which has an identification signal generator antenna. In order to improve the protection against tampering, the first vehicle antenna outputs a first signal which is received by the identification signal generator antenna. The identification signal generator determines at least one of the spatial components of the first electromagnetic field of the received first signal. The second vehicle antenna outputs a second signal which is received by the identification signal generator antenna. The identification signal generator determines at least one of the spatial components of the second electromagnetic field of the received second signal. The identification signal generator transmits the data to the vehicle. A computer determines the angle at least between the special components of the signals.

    Abstract: A method for authorizing the use of a motor vehicle, including a first antenna and a second antenna, wherein the first antenna and the second antenna are spaced apart from each other in space, by a portable identification device that has an identification device antenna. According to the method, it is determined whether the identification device is moving toward the motor vehicle, which can be determined by the identification device repeatedly identifying the field strength of the signals emitted by the motor vehicle and examining whether the field strength is increasing. Alternatively, the identification device can repeatedly identify the angle between the signals emitted by the motor vehicle and examine whether the repeatedly identified angles are increasing.

    Abstract: A method for authorizing the use of a motor, having at least one first vehicle antenna and one second vehicle antenna located at a spatial distance from one another, includes transmitting, by the first vehicle antenna, a first signal that is received by an identification provider antenna of a portable identification provider, and ascertaining, by the portable identification provider, at least one spatial component of a first electromagnetic field of the received first signal using an angle-resolving magnetic field sensor. The method also includes transmitting, by the second vehicle antenna, a second signal that is received by the identification provider antenna, and ascertaining, by the portable identification provider, at least one spatial component of a second electromagnetic field of the received second signal using the angle-resolving magnetic field sensor. An angle at least between the ascertained at least one spatial component of the first electromagnetic field and the ascertained at least one spatial component of the second electromagnetic field is then determined.

    Abstract: A charging station facility is provided having one or more charging stations for wirelessly transmitting electric energy to a vehicle. Each charging station includes a base unit which is designed to generate an electromagnetic charging field during a charging process in order to transmit electric energy to the vehicle and a transmitting and/or receiving unit which is designed to receive a request signal from a transmission unit of a vehicle or to transmit the request signal to a receiving unit of the vehicle. The request signal lies in any range of a plurality of different frequency ranges. The receiving unit is additionally designed to ascertain a signal strength of the received request signal. The charging station facility additionally includes a control and communication unit which is designed to transmit a message to a control unit of the vehicle and to a control unit of the receiving unit of the charging station selected for the charging process, wherein the message includes information on which selected frequency range the request signal is to be transmitted.

    Abstract: A method for authorizing the use of a motor vehicle, in particular a two-wheeled or four-wheeled motor vehicle, which has a first and a second antenna where the first antenna and the second antenna are spaced apart from each other, by a portable identification device which has an identification transmitter antenna. In order to increase the manipulation security of a known method, it is determined whether the identification device is moving toward the motor vehicle. This can on the one hand be determined in that the identification device repeatedly identifies the field strength of the signals emitted by the motor vehicle and identifies whether the field strength or field strengths is or are increasing. This can on the other hand be determined in that the identification device repeatedly determines the angle between the signals emitted by the motor vehicle and examines whether the repeatedly determined angles are increasing.

    Abstract: An inductive charging system for a vehicle having an electrical storage unit, in particular, an electric vehicle and a method of using the inductive charging system are provided. The inductive charging system preferably has a first coil device for a charging station and a second coil device for mounting on a vehicle, wherein the second coil device is preferably designed to magnetically interact with the first coil device. Furthermore, the inductive charging system preferably has a first positioning device, which movably supports the first coil device, wherein the system is preferably designed to produce an attractive magnetic force between the first coil device and the second coil device, which magnetic force causes a defined orientation of the first coil device in relation to the second coil device by the positioning unit.
