Abstract

A burden on an operation of an operator is reduced. A working machine includes a grid light that projects a grid light of a grid-shaped pattern, and a control unit that control the vehicle in accordance with deformation of the pattern of the grid light according to a shape of a projection spot.

First claim

What is claimed is:

1 . A vehicle, comprising:
a pattern light projection unit that projects light of a predetermined pattern to a projection spot; a control unit that controls the vehicle in accordance with deformation of the predetermined pattern according to a shape of the projection spot.

2 . The vehicle according to claim 1 ,
wherein the vehicle is a work vehicle including a work unit for executing a predetermined work, the pattern light projection unit projects the light of the predetermined pattern to a spot where the work unit works, and the control unit controls the work unit in accordance with the deformation of the pattern.

3 . The vehicle according to claim 2 , further comprising:
a machine body that travels, the work unit is provided in front of the machine body and performs snow-removal work, and the control unit controls the snow-removal work in accordance with the deformation of the pattern.

4 . The vehicle according to claim 3 ,
wherein the work unit includes an auger that removes snow, and the control unit controls rotation of the auger in accordance with the deformation of the pattern.

5 . The vehicle according to claim 4 ,
wherein when the predetermined pattern deforms in accordance with a snow wall and a snow lump in the projection spot, the control unit increases a rotational frequency of the auger.

6 . The vehicle according to claim 4 , further comprising:
a raising and lowering mechanism that raises and lowers the auger, wherein the control unit controls the raising and lowering mechanism in accordance with the deformation of the pattern.

7 . The vehicle according to claim 6 ,
wherein when the predetermined pattern deforms in accordance with a transition border of a downward slope in the projection spot, the control unit lowers the auger by the raising and lowering mechanism, and when the predetermined pattern deforms in accordance with a transition border of an upward slope in the projection spot, the control unit raises the auger by the raising and lowering mechanism.

8 . The vehicle according to claim 4 , further comprising:
a rolling mechanism that rolls the auger, wherein the control unit controls the rolling mechanism in accordance with the deformation of the pattern.

9 . The vehicle according to claim 8 ,
wherein when the predetermined pattern deforms in accordance with a lateral inclination of the projection spot, the control unit rolls the auger in such a manner that a rolling state of the auger matches with an inclination of the lateral inclination.

10 . The vehicle according to claim 4 ,
wherein the control unit controls a travel speed in accordance with the deformation of the predetermined pattern.

11 . The vehicle according to claim 10 ,
wherein when the predetermined pattern deforms in accordance with a snow wall and a snow lump in the projection spot, the control unit decreases the travel speed.

12 . The vehicle according to claim 10 ,
wherein when the predetermined pattern deforms in accordance with a level difference or a transition border of a downward slope in the projection spot, the control unit decreases the travel speed to a low speed.

13 . The vehicle according to claim 1 ,
wherein a light of the predetermined pattern is a visible light.

14 . The vehicle according to claim 1 ,
wherein the predetermined pattern is grid-shaped.
