Lateral position detection system for determining lateral position of moving body e.g. vehicle

摘要

Control facilities (30) control one of the AC magnetic field transmission systems, such that it transmits an AC magnetic field. AC magnetic field reception facilities (40a, 40b, 40A, 40B) are installed at a lower part region (B) of the self moving body, for the sequential receiving of the AC magnetic fields transmitted by the magnetic field transmitting systems, during which the moving body installed moves itself. Lateral position detecting facilities (60a, 60b) detect a lateral position (L) of the self moving body, on the basis of the AC magnetic fields, received sequentially by means of the AC magnetic field transmission systems.
