摘要:
A receiving antenna with a rigid directional pattern, that is to say with an anisotropic receiving sensitivity of the receiving antenna, is used for localizing a wheel electronics unit in a wheel of the motor vehicle. Suitable evaluation of the received electromagnetic signals is provided in order to obtain a functionality achieved by way of the displacement or rotation of the directional antenna in the case of prior solutions. In this respect, a level of the received electromagnetic signal is compared with a predefined threshold value. As the result of the comparison, the wheel electronics unit is localized as being arranged in a wheel of the first wheel group or as being arranged in a wheel of the second wheel group.

摘要:
A device and a method for determining a wheel position on a vehicle, for example an automobile. Long-wave antennae of a vehicle access system already present in the vehicle transmit a signal, which is measured by a long-wave receive unit of a tire electronic system and used to detect the position of the wheel on the vehicle. The electrical or magnetic receive field strength of the signal of a specific long-wave antenna for example is in particular detected by a tire electronic system and used to determine the position of the wheel on the vehicle.

An identification arrangement (IA1) for a vehicle (FZ1) has a vehicle-side transmitting/receiving device (SE1) for receiving an identification signal (IDS) containing an identification code (CO). The identification arrangement also has a control and evaluation device (ST1) for checking the identification code of the identification signal, as well as for outputting a control signal (LSS, ASS) for the purpose of activating a vehicle function device (BL1, HU1) such as a turn signal indicator device if the identification code was recognized as valid, or for prompting the transmitting/receiving device to retransmit the received identification signal if the identification code was recognized as invalid. In this way it is possible for an identification signal transmitted by an identification transmitter, if recognized as invalid by the identification arrangement of the vehicle, to be transmitted to one or more further vehicles in order to be checked there.

摘要:
At first, a communication connection is established between a communication terminal KE_B of an authorized user of the authorization data BD and a service control center SZ. A mobile communications connection is established between the service control center SZ and a communication device KE_SG—1 of the access arrangement ZAO after successful identification of the user. If the service control center SZ has been successfully identified the authorization data BD is updated in the memory SP of the controller SG of the access arrangement ZAO. The authorization data BD in an access arrangement ZAO in a vehicle can thus be updated at any time without the assistance of a specialist workshop.
摘要:
In a system for harmonizing a motor vehicle's status information (S1) between at least two ID transmitters (5, 6, . . . ) of a vehicle-accessing device, the vehicle status (S1), together with a reference time (t1), corresponding to the vehicle status (S1), of a reference timing element of a vehicle-side control unit (2) can be sent by the unit via at least one transceiver unit (3) to at least one first mobile ID transmitter (5) over a first radio transmission (4) and stored; and the vehicle status (S1) can be sent over a second radio transmission (7) from the first ID transmitter (5) to at least one second ID transmitter (6, . . . ) and stored. This is advantageous in that an ID transmitter (6) can obtain information about the vehicle status S1 not only via the vehicle (1) itself but also via another ID transmitter (5). The invention is especially suitable for accessing and locking systems for motor vehicles.

摘要:
A method and a device for executing a method for localization of at least one mobile transceiver embodied as an ID generator, especially as a vehicle key, in relation to a further transceiver device embodied as a base station. A request signal with at least one item of threshold information for the ID generator is transmitted by the base station. The request signal is received, if at all, by the ID generator. The field strength of the request signal is measured and compared to the at least one item of threshold information transmitted along with it and a corresponding response signal being output by the ID generator depending on the comparison.
