無人リーチ式フォークリフト及び無人リーチ式フォークリフトの操舵指示角度の補正方法

摘要

PROBLEM TO BE SOLVED: To provide an unmanned reach-type forklift and a steering instruction angle correction method for the unmanned reach type forklift, which are capable of automatically and accurately correcting a steering instruction angle.;SOLUTION: This unmanned reach-type forklift is provided with: a controller that provides a rear wheel steering instruction angle; a gyro sensor that detects the rotational angle of a currently rotated machine base; and a rear wheel encoder that detects the moving amount of a rear wheel. The controller corrects the rear wheel steering instruction angle so that a theoretical distance between a rotational center position and the rear wheel determined on the basis of a machine base size and the rotational center position and a distance between the rotational center position and the rear wheel calculated from the rotational angle of the machine base detected during the rotation of the gyro sensor and the moving amount of the rear wheel detected by the rear wheel encoder match each other.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2019,JPO&INPIT
