Guiding method for unmanned vehicle

Abstract

Abstract PURPOSE:To omit the allocation of marks, etc., by setting previously the polarization state for a magnetic guide line of an S pole from one side and a magnetic guide line of an N pole led from the other side which run in parallel with each other at a specific point on a guide path and detecting an unmanned vehicle at the specific point. CONSTITUTION:When an unmanned vehicle 10 is running on a guide path 2, an N pole sensor 12N of a guide line detector 12 detects a magnetic guide line 5 and transmits an N pole detecting signal VN. Then, an S pole sensor 12S detects a magnetic guide line 7 when the vehicle 10 enters a branch area 1 and the detector 12 reaches the passing position of a point P. The sensor 12S transmits an S pole detecting signal VS. A controller 11 receives both signals VN and VS and detects that the vehicle 10 reached the point P where the branch is started and reads the following guide path out of a map via the collation. Then, the controller 11 designates the signal VS received from the sensor 12S as a guide path detecting signal as long as the path read out of the map is equal to a guide path 3. Hereafter, the vehicle 10 picks up the guide path detecting signal and at the same time is guided by a guide line 7.
