A method, and corresponding system, of map-matching uses a first trend of position vectors (207, 215, 221, 229, 235, and 245) provided by a first position sensory system, and a second trend of position vectors (203, 211, 217, 225, and 231) provided by a redundant position sensory system.

A method, and corresponding system, of map-matching uses a first trend of position vectors (207, 215, 221, 229, 235, and 245) provided by a first position sensory system, and a second trend of position vectors (203, 211, 217, 225, and 231) provided by a redundant position sensory system. These sensory systems are preferably mounted on a vehicle but also may be a part of a hand held guidance device. The first position sensory system is preferably a GPS receiver (305) based system, and the second position sensory system is preferably a dead-reckoning sensory system, based on a compass (307) and an odometer (309). The first trend of position vectors (207, 215, 221, 229, 235, and 245) and the second trend of position vectors (203, 211, 217, 225, and 231) are compared to a trend of position vectors (212, 287, 289, 291, and 293) based on a map reference (303). A reference position vector (205, 213, 219, 227, 233, 239, 243, 246, and 249) is updated based on a matching of either or both of the first and second trends of position vectors to the trend of road segment position vectors based on the map reference. Further, one or more of the non-matching sensory system(s), or an estimated position vector associated with the non-matching sensory system(s), may be corrected influenced based on the updated reference position vector.

A system of position estimation for determining position vectors associated with road segments on a map using competitive sensory position map-matching comprising: first sensory means for providing a first position vector; at least a second sensory means for providing at least a second position vector; and means for comparing the first position vector and the at least second position vector to a road segment position vector corresponding to a road segment location determined by a reference position vector, and updating the reference position vector to correspond to a corrected position vector if at least one of the first position vector and the at least second position vector matches the road segment position vector within a predetermined criteria for a plurality of comparisons.
