[0035] The first embodiment will be described.
[0036] (The excavation site of the mine)
[0037] figure 1 It is a schematic diagram which shows an example of the excavation site of the mine in which the conveyance vehicle of this embodiment works. The transport vehicle is a dump truck 1 having a vehicle 2 and a vessel 3 provided in the vehicle 2 . The dump truck 1 transports the cargo loaded on the container 3 . Goods include at least one of excavated quarry, sand and ore.
[0038] At an excavation site of a mine, there are a loading yard LPA, a dumping yard DPA, and a travel road HL that communicates with at least one of the loading yard LPA and the dumping yard DPA. The dump truck 1 can travel on at least a part of the loading yard LPA, the dumping yard DPA, and the travel road HL. The dump truck 1 can travel on the traveling road HL and can move between the loading yard LPA and the dumping yard DPA.
[0039] In the loading yard LPA, the cargo box 3 is loaded with go...

[0177]A second embodiment will be described. In the following description, the same reference numerals are attached to the same or equivalent components as those of the above-mentioned embodiment, and the description thereof is simplified or omitted.
[0178] Figure 15 and Figure 16 Each is a schematic diagram showing an example of the relationship between the detection value (steering angle) DV of the amount of change in the traveling direction by the traveling direction detection device 10B and the invalidation by the invalidation unit 32 .
[0179] In the present embodiment, the judgment value SV includes a first judgment value SV1 and a second judgment value SV2 larger than the first judgment value SV1. The first judgment value SV1 and the second judgment value SV2 are set by the judgment value setting unit 33 . When the detected value (steering angle) DV is the reference value (reference angle), the travel device 4 travels in a straight-ahead state. The detection va...

[0192] A third embodiment will be described. In the following description, the same reference numerals are assigned to the same or equivalent components as those of the above-mentioned embodiment, and the description thereof will be simplified or omitted.
[0193] Figure 17 It is a figure which shows an example of the dump truck 1 of this embodiment. like Figure 17 As shown, the position of the dump truck 1 is detected using a global positioning system (Global Positioning System: GPS) 50 . The global positioning system 50 has GPS satellites 50S, and detects a position in a coordinate system (GPS coordinate system) in which latitude, longitude, and altitude are defined. The position of the dump truck 1 in the mine is detected by the global positioning system 50 . The dump truck 1 has a GPS receiver 49 . The control device 30 acquires the position of the dump truck 1 based on the detection result of the GPS receiver 49 .
[0194] The control device 30 can obtain the trav...
