Abstract: A method for determining the absolute position of a vehicle for the close-range positioning of same when the vehicle is being parked is described. 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. This allows particularly exact parking of the vehicle, in particular of an electrically operated vehicle for inductive charging.

Abstract: The present disclosure relates to electric vehicles and the teachings thereof may be embodied in devices and methods for inductively charging an electric vehicle. A device for inductively charging a vehicle may include: a primary coil for transmitting electrical power via a transmission region to a secondary coil during a charging process; the secondary coil associated with a vehicle disposed above the primary coil; and a dome disposed above the primary coil for removing foreign bodies entering the transmission region.

Abstract: A foreign-body detection device has coils arranged next to each other to form ring-shaped sectors. Several coils follow one another both along a circumferential direction of the ring sectors and perpendicular thereto. A power inductive charging device comprises the foreign-body detection device and a power coil arrangement on which the power inductive charging device is arranged.

Abstract: The invention relates to wireless vehicle-to-X communication by means of radio key (RKE) with a transceiver. The radio key transceiver is designed to send and receive not only data associated with the keyless driving authorization but also vehicle-to-X communication data. The radio key X communication can be used between two vehicles equipped with this radio key communication technique in order to communicate data such as positions, weather conditions or warnings quickly and reliably. This wireless communication technique using radio keys can also be used for coordinating emergency services when searching for an accident scene.

Abstract: Disclosed is a tire pressure monitoring system for motor vehicles, including a central unit (2, 7) with at least one trigger module (4), which is integrated into the central unit or connects through control lines (3) to the central unit, and with at least one tire module (6) arranged in a vehicle wheel (5), with the tire module being in communication with the central unit and the trigger module by means of wireless transmission technology, and with the tire pressure monitoring system including fewer trigger modules than tire modules.

Abstract: Disclosed is a tire pressure monitoring device for a motor vehicle. A tire pressure monitoring system with direct measurement includes a transmission device for transmitting tire pressure values determined by pressure sensors, and a tire pressure monitoring system with indirect measurement that operates on the basis of wheel speed sensors. The tire pressure monitoring system with direct measurement includes a tire pressure measuring device for measuring a tire pressure value only on each wheel of a driven vehicle axle and on at most one wheel of a non-driven axle. The tire pressure monitoring system with indirect measurement includes wheel speed sensors on the non-driven vehicle axle.

Abstract: The present device relates to a method for automatically determining the installation positions of wheels in a motor vehicle. The motor vehicle has a direct measure tire pressure monitoring system includes individual wheel tire pressure measuring devices and transmitting devices for the transfer of TPMS data containing tire air pressure values and identification numbers of the individual wheels to a receiving and evaluating device installed in or on the vehicle. The motor vehicle also includes an indirect measuring tire pressure monitoring system determining DDS data containing air pressure changes and installation positions from the rotational behavior of the individual wheels. The method includes determining correlation coefficients from the TPMS data and the DDS data by using a correlation function.

Abstract: A method for allocating wheels of a motor vehicle to a respective vehicle axle, each of the wheels includes an inflation tire whose tire pressure is monitored by a tire pressure monitoring device including at least one transmitting module in each wheel, and at least one receiving module arranged at or in the vehicle and one evaluation module, with each transmitting module transmitting tire pressure information and a wheel-specific identification number to the receiving module, which are sent to an evaluation process in the evaluation module, and tire pressure changes of the wheels are considered for the allocation, with the wheels having almost identical tire pressure changes being allocated to one vehicle axle by taking into account a vehicle-specific axle load.

Abstract: A method for determining the load exerted on the tire of a motor vehicle or to monitor the tire pressure, wherein during operation of the vehicle the pressure in the individual wheels is detected and the rotational behavior of the individual wheels is monitored, and wherein load distribution characteristic quantities are determined by comparing the rotational behavior or changes in said rotational behavior of the individual wheels during given driving conditions taking onto account preset or learned variables. Ultimately, the load exerted on the tires or pressure loss is determined from the tire pressure and the load distribution characteristic quantities.

Abstract: A system and method for aligning the beam path of a beam-emitting sensor arranged on a motor vehicle. Convenient and nevertheless highly precise setting of the beam direction of the beam-emitting element is possible if, when the vehicle is stationary, an external aligning beam propagating along or parallel to an actual direction of travel of the motor vehicle 1 hits a strictly planar surface on the sensor which reflects the aligning beam, the incident aligning beam and the reflected aligning beam are made to overlap as a result of the position of the sensor being changed.
