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.

Claim (Index 1):
A vehicle position estimation device comprising:\n a target position detection unit configured to detect a position of a target present in a periphery of a vehicle; a movement amount detection unit configured to detect an amount of movement of the vehicle; a target position storage unit configured to store positions of a target detected by the target position detection unit as target position data, based on amounts of movements detected by the movement amount detection unit; a map information acquisition unit configured to acquire map information including positions of the target; an adjustment range setting unit configured to group a portion of the target position data stored in the target position storage unit into a group according to turning states of a vehicle and, based on amounts of movements of a vehicle when the target position data are detected, set an adjustment range for the group; and a vehicle position estimation unit configured to, by matching the target position data stored in the target position storage unit with positions of a target in the map information acquired by the map information acquisition unit based on an adjustment range set by the adjustment range setting unit, estimate a vehicle position of the vehicle.
