Abstract
In this vehicle position estimation device, positions of a target present in a periphery of a vehicle is detected and, in conjunction therewith, amounts of movements of the vehicle is detected, and the positions of the target is stored as target position data, based on the amounts of movements. In addition, a portion of the target position data are grouped into a group according to turning states of the vehicle, and, based on amounts of movements of the vehicle when the target position data are detected, an adjustment range for the group is set. Further, map information including positions of the target is acquired and, by matching the target position data with the positions of the target in the map information based on the set adjustment range, a vehicle position of the vehicle is estimated.
