Abstract
An apparatus for estimating a position of a vehicle comprises: a GPS receiving unit for receiving GPS signals from satellites; a V2I communicating unit in V2I based communication with a road-side base station; an inertial sensor unit for providing motion measurements including a speed and a direction of a vehicle; a database unit for storing an electronic map and a propagation map required to estimate the position of the vehicle; a propagation map generating unit for receiving the position estimated both from the motion measurements of the vehicle and the GPS signals and for generating the propagation map by combining V2I signals on the electronic map stored on the database unit; and a control unit for estimating the position of the vehicle using the propagation map based on the V2I signals received from the V2I communicating unit and compensating the position of the vehicle.
