US Patent 10890453 Vehicle localization device

A vehicle localization device includes: a target database; a target recognition unit configured to recognize, based on a detection result of an in-vehicle sensor, a relative position of the first target relative to a vehicle and a relative position of the second target relative to the vehicle; a lateral position estimation unit configured to estimate a lateral position of the vehicle and a direction of the vehicle based on the relative position of the first target relative to the vehicle and the position information on the first target on the map; and a longitudinal position estimation unit configured to estimate a longitudinal position of the vehicle by reflecting the lateral position of the vehicle and the direction of the vehicle.
