A control device for guided travel of an unmanned vehicle, in which the unmanned vehicle is guided to travel by receiving a signal sent from a GPS satellite by the unmanned vehicle, measuring its own vehicle position based on the signal, and controlling such that a positional shift between the vehicle position and a target point that is a passing point sequentially set on a target traveling course falls into an allowable range for controlling error, wherein a guidable range is set in advance such that a position measurement error is added to the allowable range for controlling error; the position measurement error is obtained based on position measurement accuracy information from the signal; the allowable range for controlling error is changed according to the obtained position measurement error; and control is performed such that the positional shift falls into the changed allowable range for controlling error.

Control device for guided travel of unmanned vehicle

Guiding speed is increased while an unmanned vehicle is prevented from straying from a travel passage width, to improve the work efficiency. Target speed of the unmanned vehicle increases as a distance between a current position of the unmanned vehicle and a guidable borderline increases, and the target speed of the unmanned vehicle decreases as the distance between the current position of the unmanned vehicle and a guidable borderline decreases. The unmanned vehicle travels, along a travel path having adjacent inbound/outbound lanes, in a direction opposite to a direction of a vehicle on an oncoming lane. If it is determined that the vehicle traveling along the oncoming lane is approaching the unmanned vehicle, then the target speed of the unmanned vehicle is reduced, whereby the unmanned vehicle is caused to travel at a low guiding speed.
