Vehicle position determining apparatus

摘要: Apparatus for determining the position of a mobile vehicle relative to fixed location marker device which comprises coil energized emit magnetic field composed lines flux extending radially and arcuately from ends coil's longitudinal axis. A sensor unit mounted on four identical sensing coils each responsive frequency having major These are supported in two pairs with axes pair disposed either side common central plane parallel thereto, this transversely axis coil. Each is arranged an X pattern their cross other medially perpendicularly define center pair. The centers spaced apart distance base line at 45 degree angle. Position signals processed produce Y coordinate values indicating device. may be inductively excited antenna vehicle.
