Title: VEHICLE POSITION ESTIMATION DEVICE, VEHICLE POSITION ESTIMATION METHOD
Abstract:
In this vehicle position estimation device, the position of a target present on the periphery of a vehicle is detected, the amount of movement of the vehicle is detected, and the position of the target is stored as object position data on the basis of the detected amount of movement. Further, a map database (14) pre-stores map information including the position of the target, and, by comparing the target position data and the map information, estimates the position of the vehicle. Further, a turning position Pt1 of the vehicle is detected. Then, target position data is maintained for the range from the present location Pn to a set distance D1, and for the range from the turning point Pt1 to a point [Pt1-D2] obtained by backtracking a set distance D2.
