1. A vehicle navigation system for use in vehicles traveling on roadways comprising:
a vehicle including an onboard computer and accelerometers and gyroscopes, the accelerometers and gyroscopes coupled to provide signals compensating for acceleration, velocity, and centripetal forces produced by movement of the vehicle, the vehicle having a longitudinal slope (SL) and a cross slope (SX) defining a vehicle orientation relative to the roadway;
a coordinate system slope map supplied in the onboard computer;
a simulated free-floating bubble within the onboard computer, the bubble having a fixed orientation relative to the vehicle and the bubble having a coordinate locus dependent upon the vehicle longitudinal slope (SL) and cross slope (Sx), and the signals compensating for acceleration, velocity, the centripetal forces produced by movement of the vehicle applied to the simulated bubble so that the position of the bubble and coordinate locus is dependent only upon the orientation of the vehicle; and
the onboard computer comparing the coordinate system slope map to the coordinate locus of the bubble at each location along the slope map and providing a location when a coordinate locus of the slope map and the coordinate locus of the bubble match.
