<p><P>PROBLEM TO BE SOLVED: To provide a turn control method for an unmanned carrier vehicle which realizes stable guided travel movement along a guide zone without derailment at high-speed operation. <P>SOLUTION: The turn control of each driving wheel of a truck body 1 is executed by switching between a high-speed operation guide mode (a front guide mode or a rear guide mode), which fixes shafts of both driving wheels of rear side of moving direction in neutral and turns both shaft of the driving wheel of front sides of the moving direction, and a low-speed operation guide mode (a front and rear guide mode) which turns each of all shafts (the first shaft - the fourth shaft) of each driving wheel. In this way, in the high-speed operation guide mode, straight-moving performance is improved and stable guide movement along the moving guide zone C can be realized without derailment even at high-speed operation, and in the low-speed operation guide mode, driving accuracy along the moving guide zone is improved and stable guide movement along the moving guide zone C can be realized without derailment even where the moving path is curved. <P>COPYRIGHT: (C)2004,JPO</p> |
