no. 1 approach

[0038] The first embodiment will be described.

[0039] (excavation site of the mine)

[0040] figure 1 It is a schematic diagram showing an example of an excavation site of a mine where the transportation vehicle of this embodiment operates. The transportation vehicle is a dump truck 1 including a vehicle 2 and a vessel 3 provided on the vehicle 2 . The dump truck 1 transports cargo loaded in the container 3 . The cargo includes at least one of excavated quarry, sand and ore.

[0041] The excavation site of the mine is provided with a loading area LPA, a soil dumping area DPA, and a running road HL communicating with at least one of the loading area LPA and the soil dumping area DPA. The dump truck 1 can travel on at least a part of the loading yard LPA, the dumping yard DPA, and the traveling road HL. The dump truck 1 can travel on the travel road HL and move between the loading area LPA and the dumping area DPA.

[0042] At the loading dock LPA, the container 3 is loa...

no. 2 approach

[0179] A second 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.

[0180] Figure 13 It is a schematic diagram which shows an example of the control system 300B of this embodiment. The control system 300B has: a first operation unit 41 arranged in the cab 8 ; and a second operation unit 42 arranged in the cab 8 . The first operation unit 41 and the second operation unit 42 are operated by the operator WM. An operation signal Ra generated by operating the first operation unit 41 is output to the control device 30 . The operation signal Rb generated by operating the second operation unit 42 is output to the control device 30 .

[0181] as reference figure 1 As described above, cargo is loaded into the container 3 at the loading area LPA of the mine. The dump truck 1 in the loaded stat...

no. 3 approach

[0189] 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.

[0190] Figure 14 It is a flowchart showing an example of the control method of the dump truck 1 according to the present embodiment. The detection result of the running state detection device 10 is output to the control device 30, and the control device 30 acquires information on the running speed Vt of the dump truck 1 (step SB1).

[0191] Similar to the above-mentioned embodiment, the detection period of the traveling state detection device 10 is Gt (for example, not less than 1 ms and not more than 100 ms). The running state detection device 10 continues to output detection results to the control device 30 at predetermined time intervals Gt. The control device 30 acquires the detection result. The control device 30 ...

Abstract

Provided is a transport vehicle that can reduce damage from collisions with objects and prevent reduction of working efficiency. The transport vehicle is provided with a vehicle, a vessel provided to the vehicle, a travelling conditions detecting device that detects the travelling conditions of the vehicle, an object detecting device that detects objects in front of the vehicle, and a collision determining unit that determines the potential for a collision with an object on the basis of the load condition of baggage in the vessel, the detection results of the travelling conditions detecting device, and the detection results of the object detecting device.

Description

technical field [0001] The invention relates to a transport vehicle and a control method for the transport vehicle. Background technique [0002] At the excavation site of a mine, a transport vehicle such as a dump truck performs work, and the transport vehicle transports quarried stones and the like. The transportation vehicle runs on the road installed in the mine in a loaded state loaded with quarry or other cargo or in an empty state without loaded cargo. When the transport vehicle collides with an object while driving, the transport vehicle will be damaged, which will hinder the transport work such as quarrying and reduce the productivity of the excavation site. Therefore, a collision prevention device as disclosed in Patent Document 1 is used in a transport vehicle. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Application Publication No. 06-051904 Contents of the invention [0006] The problem to be solved b...
