A control system for an unmanned carrier vehicle, capable of automatically and independently traveling along a guiding line laid on a floor, provides a steering angle control unit and/or a velocity control unit. Herein, when the unmanned carrier vehicle is deviated from the guiding line, its deviation is detected. By performing a time-differentiation on the deviation, a deviation direction of the unmanned carrier vehicle is computed. In addition, a steering angle of a steering wheel of the unmanned carrier vehicle is detected by a sensor provided at a wheel of the unmanned carrier vehicle. Based on a result of a fuzzy inference to be performed on the deviation, deviation direction and steering angle, the steering angle control unit controls the steering angle of the unmanned carrier vehicle. Similarly, the velocity control unit controls a traveling velocity of the unmanned carrier vehicle. Incidentally, the fuzzy inference is performed in accordance with the predetermined fuzzy control regulation.

Control system for unmanned carrier vehicle

A guidance conductor for a driverless vehicle which is controlled to move along a track way by detecting an induction field. The guidance conductor is a continuous conductor having portions laid parallel in a predetermined spaced relation to each within the track way so as to form substantially a closed circuit, and is energized by a high frequency source. The guidance conductor also has loop portions in which only one portion of the conductor is laid. The driverless vehicle is adapted to detect the induction field generated by the guidance conductor.
