Abstract: A device and a corresponding method are provided for reducing an electromagnetic field in a vehicle. A control unit for a vehicle is designed to determine one or more properties of an electromagnetic interference field. The control unit is further designed to incite an emission unit in the vehicle to emit an opposing field which reduces a strength of the interference field in a first zone around and/or in 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.

Abstract: A radio remote control for controlling at least one first vehicle function that is relevant for functional safety, and further vehicle functions not related to functional safety. The remote control generates and wirelessly transmits transmission data to the vehicle for implementing the first vehicle function in response to a user input and a security information, provided upon actuation of a user interface and a security input actuator, respectively, by the user. In the case of a user input that is associated with the first vehicle function, the security information is only used to generate transmission data that causes the first vehicle function to be carried out if the security input actuator was actuated.

Abstract: A system includes a vehicle having an automatic radio-based vehicle safety unit and an access control device. An access element is assigned to the vehicle safety unit, where the vehicle safety unit has several low-frequency transmitting antennas, and the access element has a low-frequency receiver. By means of the access control device, the spatial position of the access element relative to the vehicle is detectable based on the principle of electromagnetic distance and angle measuring between the transmitting antennas and the receiver. The system further includes a vehicle-external induction charging unit having a primary coil, and the vehicle comprises a secondary coil for the inductive charging of the vehicle at the induction charging unit, where the induction charging unit has at least one low-frequency receiving antenna.

Abstract: A radio remote control according to the invention is used to control at least one first vehicle function that is relevant for functional safety, and also used to control further vehicle functions not related to functional safety. The remote control comprises input means for the user selection of vehicle functions and for obtaining a user input corresponding to the selected vehicle function. The remote control according to the invention additionally comprises a security device for safeguarding the first vehicle function. The security device itself comprises a security input means, which must be actuated for the first vehicle function to be carried out. The security device moreover comprises a security circuit that is coupled to the security input means and includes security information.

Abstract: A system and method is provided for wireless remote control of the operation of vehicle components such as a door lock or an entertainment system. An electronic host device, such as a PDA or a mobile telephone, is coupled to a vehicle-specific transponder, and a user interface program executed on the host device allows a user to select a desired vehicle component operating command for execution. The selected operating command is sent to the transponder for transmission to the vehicle, and a vehicle receiver forwards the selected command to the target component for execution. The transponder may contain vehicle-specific authorization information which the vehicle receiver may use to verify authorization to operate the vehicle. Additionally, information stored on the host device such as telephone numbers and addresses may be transferred via the transponder to vehicle components which may use such information for task such as navigation of initiating telephone calls.
