Title:
VEHICLE POSITIONING METHOD AND POSITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/005109
Kind Code:
A1
Abstract:
A vehicle positioning system (1) includes: a pair of right and left ground speed sensors (12) for optically detecting a ground speed, which is a speed relative to a road surface; a physical quantity arithmetic circuit (101) for obtaining a physical quantity required for autonomous navigation from the ground speed detected by the pair of right and left ground speed sensors (12); and a positioning circuit (103) for measuring a relative position to a reference position when the vehicle moves past the reference position. The positioning circuit (103) measures the relative position by using the physical quantity obtained by the physical quantity arithmetic circuit (101).
