A method for determining the position of a non-motorized road user including ascertaining a first geodetic position of the road user in a position determination device, which uses a global navigation satellite system, of the terminal, and transmitting the first geodetic position to a traffic device. In a control unit of the traffic device, ascertaining a second geodetic position of the road user from a geodetic traffic device position and a relative position ascertained from sensor data, showing the road user, of at least one surroundings sensor of the traffic device. At least if a limiting value for a deviation of the first position from the second position is exceeded, transmitting an item of deviation information describing the second position and/or the deviation from the traffic device to the mobile terminal, and using the deviation information to correct the position ascertainment in the position determination device.

Method for determining the position of a non-motorized road user and traffic device

A method for operating a communication network comprising a plurality of motor vehicles, wherein the motor vehicles each have a sensor device having at least one environmental sensor, wherein at least one motor vehicle, when a malfunction of an environmental sensor is found by its sensor device, transmits the status data describing the malfunction and including position data of the motor vehicle to at least one external evaluation device for determining interference area information describing an interference area for environmental sensors of the motor vehicles.

Method for operating a communication network comprising a plurality of motor vehicles, and motor vehicle

In a method for associating a transmitter which transmits at least one communication information in a car-to-car communication with an object in a receiving motor vehicle, wherein the object is described by environmental data from at least one environmental sensor, wherein the association occurs based on comparing environmental data from at least one environmental sensor of the motor vehicle having the transmitter with corresponding environmental data of the receiving motor vehicle.

Method for associating a transmitter with a detected object in car-to-car communication and motor vehicle

The invention relates to a method for geographically localizing triggers for malfunctions in a motor vehicle, wherein the malfunction of the motor vehicle is detected and an error entry describing the malfunction in an error memory of the motor vehicle is generated, and a geo-position (XY) of the motor vehicle is detected and stored by a localization device of the motor vehicle pp(). Subsequently, during an error diagnosis of the motor vehicle, the error entry from the error memory of the motor vehicle is read out by an analysis device located outside the motor vehicle and a trigger class () describing a trigger of the malfunction is received for the error entry. The geo-position (XY) of the motor vehicle and the malfunction are stored in a corresponding digital map for the trigger class.

Geographically locating malfunction sources for motor vehicles

A method for supporting a driver of a vehicle, in particular a motor vehicle, includes automatically detecting with a navigation device of the vehicle whether the vehicle has deviated from a defined driving route determined by the navigation device. When the vehicle has deviated from the defined driving route, it is determined with the navigation device whether an amount of propulsion energy stored in an energy storage device of the vehicle is sufficient to still reach at least one energy refilling station. When an energy refilling station can no longer be reached with the vehicle automatically a phone connection with a vehicle external help center is established with a phone device of the vehicle, prior to the vehicle becoming stranded, or it is automatically displayed to the driver with a display device of the vehicle prior to the vehicle becoming stranded, to establish a phone connection with a vehicle external help central.

Method and device for supporting a driver of a vehicle

A method for determining a spatially resolved extent of error for position finding with a global navigation satellite system for a target area of interest using field data from a plurality of field apparatuses, particularly motor vehicles, each having a receiver for the global navigation satellite system and which are at least intermittently situated in the target area, comprising the following steps: ascertainment by the field apparatuses of at least one field data record comprising a current GNSS position in the target area and an error value associated with said position, transmission of the field data records to a central computation device, updating of an error map containing the extents of error for various positions and/or subareas of the target area by statistical evaluation of the field data records in the central computation device.

Method for determining a spatially resolved extent of error for position finding with a GNSS

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.
