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.

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.

Method and system for autonomously developing or augmenting geographical databases by mining uncoordinated probe data

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.
