An inductive positioning method is performed, wherein a first transmitter in the infrastructure or in the vehicle is excited to generate a positioning magnetic field and a second transmitter in the infrastructure or in the vehicle is excited to generate a positioning signal. The positioning magnetic field and the positioning signal are received by a reception device in the vehicle or in the infrastructure and the received positioning magnetic field and positioning signal are taken as a basis for ascertaining the absolute position of the vehicle.

Abstract: An electrical coupling state is monitored between an inductive load and a circuit configuration. The latter has a first and a second coupling point for coupling to the inductive load. A first voltage value is determined between the first and second coupling points. The first voltage value is tested for the occurrence of a characteristic voltage pulse, which can be triggered by reduction of a magnetic flux in the inductive load by way of a steep-edged change in the amount of current flow through the inductive load. An error is identified in the coupling state if the characteristic voltage pulse does not occur within a predefinable time period. The absence of an error in the coupling state is also identified if the voltage pulse does occur.

Abstract: A remote-controlled access control device includes a stationary transceiver device with a triggering device and a portable transponder. The stationary transceiver device transmits an interrogation code signal in response to the triggering device being activated. The portable transponder receives the interrogation code signal and has a manually activatable activation element. The portable transponder generates a code signal and transmits, together with the code signal, information indicating whether the code signal is generated in response to the interrogation code signal or in response to the activation element being activated. The stationary transceiver device receives the information together with the code signal and generates an unlocking signal based on an evaluation of the code signal with the information indicating whether the code signal is generated in response to the interrogation code signal or in response to the activation element being activated.

Abstract: An access control device for a motor vehicle and a method for setting the sensitivity of an access control device, include a plurality of ferrite antennas disposed in a door handle of the motor vehicle. The individual ferrite antennas are inclined with respect to one another and with respect to the door surface. Consequently, a widely fanned magnetic field is produced within which a request signal can readily be received by a portable encoder. In order to ensure that interference signals have only little effect on the reception of a request signal, the reception sensitivity of the encoder is increased only after a very powerful advance signal has been received.

Abstract: A control system for controlling an object function includes a base station and a portable code transmitter. The base station is at the object and has a transceiver unit for transmitting an interrogation signal. The code transmitter emits a response signal with a code information item in response thereto. The base station checks an authorization of the code information item contained in the response signal. The base station and/or the code transmitter determines a time period between a transmission of a part of the interrogation signal and a reception of a part thereof obtained in reaction thereto, and compares the time period with a predefined reference time period. The base station enables the object-specific function only if the measured time period is shorter than the reference time period even if the code information item of the response signal is correct.
