PROBLEM TO BE SOLVED: To provide a mobile body position estimating device and the like capable of estimating a present position display with good apparent precision without respect to an error included in road link data.;SOLUTION: In this mobile body position estimation device, the probability of an estimated mobile body position A1 matching a road link R0 on a map calculated from estimation navigation and map matching is determined from a position A2 positioned by radio navigation by using an expanded error circle E using the sum of a radio navigation error D and a road link error as a radius.;COPYRIGHT: (C)2002,JPO
