Title:
BACK TRAVELING CONTROL METHOD FOR UNMANNED CARRIER
Document Type and Number:
Japanese Patent JP3275364
Kind Code:
B2
Abstract:
PURPOSE: To prevent an out-course state and to improve the traveling safety of an unmanned carrier when the unmanned carrier travels linearly and backward at a high speed.
CONSTITUTION: The unmanned carrier 1 is provided with two rear wheels and a front wheel 2 serving as a steering wheel and travels backward while detecting a guide line 10 by a quide sensor 5b. Meanwhile, a virtual guide sensor 5b is supposed and it is presumed that the line 10 is detected at a sensing point P7. Then, a set steering angle θ is calculated according to a segment connecting the point P7 to the center point P1 between both wheels 3 and a detecting angle αformed by the point P7 and the center line C2 of the AGV body.
