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.

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.

A method, an evaluation system and a cooperative vehicle for predicting at least one congestion parameter are proposed. The method involves a detecting of a traffic density-, a detecting of a current position x which is present during the detecting of the traffic density-and a relaying of the traffic density-and the current position x to an evaluation unit. Moreover, the method includes an evaluation of the traffic density-and a providing of at least one congestion parameter.

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.

A method for coordinating operation of motor vehicles with a coordination device having a sensor, a computing device and a communication device includes determining from sensor data location and movement information of the motor vehicles, calculating an expected trajectory for each motor vehicle from the location and movement information, checking whether trajectories of different motor vehicles spatially and temporally overlap so as to create a conflict, in the event of a conflict transmitting a driving instruction to at least one motor vehicle, and executing the driving instruction or displaying the driving instruction on a display device of the at least one motor vehicle.
