A method for position determination, in particular of a motor vehicle, includes optically capturing an object having a known geographic position and matching the geographic position of the object with stored map data. The object may be a road sign having distance information, which is optically recognized at the vehicle. The distance information is subsequently evaluated using optical character recognition.

Method for position determination

A method provides an operating strategy for a target vehicle which is located together with other foreign vehicles on a track section of a road track. A communication unit of the target vehicle or of an external data server is connected to a respective communication unit of the foreign vehicles via an ad-hoc network, in particular via a car-to-X communication. A foreign vehicle communicates a position signal and/or an information to an operating parameter. A processing unit determines the positions of the foreign vehicles and can determine a digital model for a current traffic situation in the track section using information related to the operating parameter. The digital model describes the track section and the foreign vehicles located thereon and serves as a basis for an operating strategy for operating the target vehicle. A driving recommendation produces a model output for the driver or triggers automatic driving.

Method for providing an operating strategy for a motor vehicle

Motor vehicles as well as infrastructure stations, which are stationary and which are installed on the side of the road such as traffic light systems for example, are provided as participants in a Car-to-X network. The vehicles include an automobile radio together with the communication unit for communicating with other participants of the network. In the event that such a vehicle travels through a region, for example a tunnel or a forest, in which a direct antenna reception of the radio signal of the radio station set in the automobile radio is poor or impossible and thus the reception quality of said radio signal is poor, the driver can be irritated or angered due to static or other disruptive noises as well as a loss of sound. Reception of radio signals in a Car-to-X communication system is improved by forwarding radio signals from one user to another.
