Abstract: In at least one embodiment, a method is disclosed that includes determining algorithmically a a plurality of vehicle cost values for traveling a plurality of road segments in a vehicle based at least in part on vehicle cost data derived at least in part from position derivative data obtained from at least one vehicle that traveled the road segments (S1); associating each of the plurality of road segments with at least one of the vehicle cost values (S2); and storing the determined vehicle cost values in a memory device (S3). In at least one embodiment, a method for determining a route of travel from a first location to a second location is disclosed. Other embodiments include a map database, storable on a storage medium; a device including a memory (230) storing a map database, a processor (210) and an output device (260); and a device for use in a vehicle, where the device includes a GPS receiver (250), a memory (230) and a processor (210).

Abstract: A system and method for a vehicle to display to observers in proximity to said vehicle information indicative of or chosen by the occupant or person otherwise associated with said vehicle. This information may be any form and constitutes the avatar for said occupant or person. The avatar is displayed as a statement of identity, individuality or personal expression that personalizes a vehicle in a reconfigurable manner. This is particularly applicable to shared vehicles enabling them to provide a display related to a specific occupant or associated person.

Abstract: A method and system of generating a horizon for use by an ADAS of a vehicle involving recording the historic movements of the vehicle on a road network, and using the recorded data to determine at least a most probable path that the vehicle will take at decision point of the road network.

Abstract: In a method for creating a digital representation of a transportation network location measurement data is acquired, and a plurality of maneuvers between choke points are generated from the location measurement data. The digital representation of the transportation network is then created and stored based on the plurality of maneuvers.

Abstract: A method of generating a horizon for use by an ADAS of a vehicle involves using historical vehicle probe data to determine the likelihood that different outgoing paths are taken at a decision point along a currently traversed road segment, and deriving a probability that each path may be taken. The probability is based on historical paths taken by vehicles at the decision point as indicated by the vehicle probe data.

Abstract: In a method for preventing rollover for a vehicle traveling on a road, for each present position of the vehicle as it moves forward, its speed is forecasted for future positions of the vehicle on the road, based on an assumption regarding driving style of the operator, and based on a map containing road geometry data and statistical speed data for vehicles traveling said road. At each such present position of the vehicle, a maximum safe speed is determined for points on the road forward of the vehicle, based on a maximum lateral acceleration, the road geometry and the vehicle parameters. A rollover warning is generated for any current position of the vehicle at which the forecasted future speed for at least one particular point on the road forward of the vehicle exceeds the determined maximum safe speed at particular point.

Abstract: A method and system are provided for developing geospatial information concerning a particular area using a plurality of uncoordinated probe vehicles moving in the area. The probe vehicles are equipped with a position determining system and gather probe vehicle specific geospatial information as the vehicles move in the area. This probe vehicle specific information is combined over time into a data set. A central processor analyzes the data set to determine geospatial information having a higher quality than that gathered by the individual probe vehicles for the particular area.

Abstract: A system and method are provided for using multiple GPS antennas and corresponding processors on a single vehicle in order to both maintain position information when fewer than four GPS satellites are visible and to reduce position errors by minimizing multipath induced errors using information combined from the multiple systems. The system and method calculates differential path lengths between the received position information signals and at least two antenna/processor pairs to determine cone angles therebetween. The position information of the mobile vehicle is maintained based on the initial position information and the determined cone angles.
