LOCATION SEARCH METHOD OF STRONG COMPOSITION FRAME BY USING NAVIGATION SYSTEM

摘要

The present invention relates to a strong composite structure position detection device in a vehicle navigation system, wherein a map data read from a storage medium is displayed on a monitor, and a vehicle having a vehicle navigation system capable of identifying the position of the own vehicle through a GPS satellite. In the case, when the GPS signal from the GPS satellite received through the GPS receiver 42 is applied through the filter unit 46 and the first position correction unit 48 for performing a correction in accordance with the position of the vehicle being driven; A plane coordinate system conversion unit 50 which receives the corrected position signal of the vehicle from the first position correction unit 48 and converts the plane signal data into plane coordinate data as an absolute current position of the vehicle; and the plane coordinate system conversion unit 50. When the plane coordinate conversion signal from is applied through the filter unit 52, the vehicle is moved from the second position compensator 54 which corrects the current position of the vehicle which is still running, and the geomagnetic sensor 22 and the vehicle speed sensor 24. Of A space for generating spatial plane coordinate data based on a processor 56 for detecting a current position, a plane coordinate conversion signal from the second position correction 54, and a current position of the vehicle from the processor 56; A coordinate matching unit 58 and a map matching unit 60 for correcting the cumulative error of the vehicle in a timely manner based on the spatial position data of the vehicle applied from the spatial coordinate system converting unit 58 are characterized.
