no. 1 approach

[0035] The first embodiment will be described.

[0036] (excavation site of the mine)

[0037] 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.

[0038] 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.

[0039] At the loading dock LPA, the container 3 is loa...

no. 2 approach

[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...

no. 3 approach

[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. Such as 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 t...

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 travelling device that is able to change a travelling direction between a straight-ahead state and a non-straight-ahead state; a determination value setting unit that sets a determination value related to an amount of change in the travelling direction from the straight-ahead direction; a collision avoidance system, which has 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 detection results from the object detecting device, said collision avoidance system being able to perform a process to reduce damage from a collision with an object; and an invalidating unit that invalidates at least some processes of the collision avoidance system on the basis of the detected value and the determined value of the amount of change in the travelling direction from the straight-ahead state.

Description

technical field [0001] The invention relates to a transport vehicle, a dump truck 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.
