Abstract: An automatic supply system of a consumable material includes: an automatic supply device that automatically supplies a consumable material to a vehicle capable of being loaded with a cargo; and a control device that obtains loading information indicating whether or not the cargo is loaded on the vehicle, and is able to control an automatic supply of the consumable material to the vehicle based on the obtained loading information, wherein, when the control device determines that the cargo is loaded on the vehicle from the obtained loading information, the control device controls the automatic supply device not to perform the automatic supply of the consumable material to the vehicle.

Abstract: Leveling operation can be effectively performed at a discharge site without increasing a cost of vehicles, and a running course can be easily generated in a short time and at a low-cost. Based on each of measured position data of a survey line 20 of a discharge site 21, a normal line Lc normal to the survey line 20 is obtained, a target discharge position 26? is positioned at a prescribed distance away from the survey line 20 in an inward direction of the discharge site 21 based on the normal line Lc, and then data of a running course 27 in which a reference approach direction 31 to approach the target discharge position 26? is a direction normal to the survey line 20 are generated.

Abstract: A restricted area (60) is created based on positional information of a manned vehicle (20) traveling one of outward/return lanes (51, 52), and a detour course (72) is created based on information of the restricted area (60). Information on the detour course (72) is provided to the unmanned vehicles (10, 11) and the manned vehicle (20). Based on the positional information of the unmanned vehicles (10, 11) which proceed towards each other from the opposite directions with the restricted area (60) therebetween, the unmanned vehicle (11) on the lane (52) which is the opposite side of the restricted area (60) is blocked at a block position (61B) and at the same time a travel permission command for permitting traveling the detour course (72) is issued to the unmanned vehicle (10) traveling the lane (51) on the restricted area side so that the unmanned vehicle (10) travels the detour course (72).

Abstract: In detecting an obstacle of a vehicle, to be able to eliminate dead angle, shorten a detection period and reduce erroneous detection of the obstacle, when a vehicle runs on a running road, by pivoting a pivoting radar in a direction in accordance with a progressing direction of the vehicle, a total or a portion of a detection range of the pivoting radar can be made to be outside of a detection range of fixed radars. Therefore, an obstacle in a range outside of the detection range of the fixed radars can be detected by the pivoting radar.

Abstract: An unmanned vehicle running system, capable of reducing a stop time of a vehicle by immediately judging whether or not an obstacle blocks the passage when detecting the obstacle. For this purpose, the unmanned vehicle running system has a plurality of vehicles (1) running without a driver in a predetermined course (3) while detecting the current position and a central monitor station (2) for monitoring operations of the plurality of vehicles, wherein each of said vehicles is provided with a phototaking device (24) for taking a photo of the course, with a vehicle communication unit (23) for transmitting the taken image to the central monitor station, and with an obstacle detecting unit (5) for detecting an obstacle (4) which blocks the passage, wherein the central monitor station is provided with a central communication unit (8) for receiving the image and with a monitor (9) for displaying the image, and wherein the phototaking device takes a photo when the obstacle detecting unit detects an obstacle.

Abstract: The present invention prevents the interference of vehicles traveling on-coming to each other when a plurality of vehicles are traveling on-coming to each other on a traveling path with a predetermined road width without increase in cost caused by setting a wide course width and without a drop in work efficiency caused by decreasing velocity. If one of the vehicles detects the other vehicle by its obstacle detection means when the vehicles are traveling on-coming to each other, the vehicle which detects the other vehicle begins deceleration to stop itself. At the same time, this vehicle transmits a deceleration control command for stopping the other vehicle to the other vehicle via transmission/reception means, therefore the other vehicle starts deceleration even if this vehicle cannot detect an obstacle.
