<p>PROBLEM TO BE SOLVED: To provide an unmanned running controller to reduce an error in a dead-reckoning navigation even when positioning is not performed for a long time by a GPS(global positioning system). SOLUTION: This controller is provided with a dead-reckoning navigation controller 15 to detect a relative position of a vehicle 1 from a specified absolute position by a running sensor mounted on the vehicle 1, a GPS controller 14 to detect an absolute position of the vehicle by GPS communication from a GPS satellite 5, a running controller 13 to control speed and steering of the vehicle 1 and a vehicle controller 16 to correct the relative position by every specified time by the GPS and to make the vehicle 1 run on a specified route for a specified time by the dead-reckoning navigation, precision of GPS positioning information is decided, based on the GPS communication from the GPS controller 14, a running condition to indicate a running state of the vehicle 1 is decided, based on decision of the precision and an instruction is outputted to the running controller 13, based on this decision.</p> |
