CURRENT POSITION DETECTOR FOR VEHICLE

摘要

PURPOSE: To detect a more proper current position for the scattering of a position-measurement position without causing any time delay. CONSTITUTION: The position-measurement position of a vehicle is repeatedly obtained by a position-measurement operation part 1b and at the same time the speed vector of the vehicle is detected by a speed azimuth operation part 1c. A filtering part 1d estimates the position of the vehicle at a next timing by a speed vector and a current position and performs filtering processing for updating a current position based on the averaging processing between the estimation position and the position-measurement position of the vehicle at a next timing obtained by the position-measurement operation part 1b.
