Abstract:
1. A control device for guided travel of an unmanned vehicle, in which the unmanned vehicle is guided to travel with a signal sent from a GPS satellite, measuring its own vehicle position based on the received signal, and controlling such that a positional shift (ΔX) between the measured 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, the control device comprising, a control system that sets a guidable range to a constant value in advance such that a position measurement error (2Xp) is added to the allowable range for controlling error; a GPS position control measurement device that extracts and outputs position measurement accuracy information acquired from the signal sent from the GPS satellite; and a controller that controls the travel of the unmanned vehicle by setting the position measurement error (2Xp) based on the position measurement accuracy information output from the GPS position control measurement device, by setting the allowable range for controlling error based on the position measurement error (2Xp), and by making the positional shift (ΔX) between the measured vehicle position and the target point that is the passing point sequentially set on the target traveling course fall into the allowable range for controlling error set based on the position measurement error (2Xp).
