PROBLEM TO BE SOLVED: To improve the efficiency of the traveling of a vehicle and to improve the efficiency of delivery by a delivery vehicle by automatically updating the data base of information relating to a beacon. SOLUTION: The information relating to the beacon including the position of the beacon is stored in a road map/beacon information memory 6, and when the vehicle passes through the communication area of the beacon, a position is discriminated by a position discrimination part 1c and the discriminated position and the position of the same beacon stored in the road map/beacon information memory 6 are compared. As the result of the comparison, when it is judged that both positions are separated for more than a threshold value, instead of the position of the beacon stored in the road map/beacon information memory 6, the position discriminated by the position discrimination part 1c is displayed at a display device 12 along with a road map as the position of the beacon. |
