ABSTRACT:
A hybrid vehicle navigation system employs both GPS and dead reckoning sensors, working in parallel, to produce a sensed and a calculated position, respectively. The sensed and the calculated positions are compared to a road data base to determine separate correction factors required to correct the sensed and the calculated positions. In one embodiment, the system employs either the sensed or calculated position for navigation depending on which has the smaller correction factor.
