TURNING CONTROL METHOD FOR UNATTENDED VEHICLE

Title:

TURNING CONTROL METHOD FOR UNATTENDED VEHICLE

Document Type and Number:

Japanese Patent JPS63163511

Kind Code:

A

Abstract:

PURPOSE:To surely transfer from one of guide lines crossing each other to the other by detecting distances from the other guide line by outputs of first-fourth detectors to turn an unattended vehicle onto the other guide line. CONSTITUTION:An unattended vehicle A is provided with a detecting means B to detect positions of guide lines 1 and 2, and the detecting means B is provided with first-fourth detectors 3-6, and first and second detectors 3 and 4 are provided on front left and right parts of the unattended vehicle A and third and fourth detectors 5 and 6 are provided on rear left and right parts of the unattended vehicle A. Consequently, when the unattended vehicle A is transferred from the guide line 2 to the crossing guide line 2 by spinning and turning, detectors 3-6 are so filtered that the frequency of the guide line 2 can be detected and the unattended vehicle A is stopped when the difference (voltage difference) between outputs of detectors 3-6, for example, detectors 3 and 4 is lower than a threshold, and then, the unattended vehicle A is stopped and positioned on the guide line 2. Thus, the unattended vehicle A is surely transferred to the guide line 2.
