Vehicle
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.
1. A vehicle that is a working machine having a machine body that travels and an auger provided in front of the machine body and performs snow-removal work, comprising:
a light that projects light of a predetermined pattern to a spot where the snow-removal work is performed; and
a control unit having a CPU, the control unit detects a deformation of the predetermined pattern, and performs traveling speed control of the machine body and driving control of the auger based upon the deformation of the predetermined pattern,
wherein the control unit performs control to increase a rotational frequency of the auger and decrease the travel speed of the machine body when the control unit determines that either a snow wall or a snow lump is in the spot where the predetermined pattern is projected in accordance with the deformation of the predetermined pattern while the machine body is traveling and the auger is rotationally driven at a predetermined rotational frequency.
2. The vehicle according to claim 1 , 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 predetermined pattern.
3. The vehicle according to claim 2 ,
wherein when the predetermined pattern deforms in accordance with a transition border of a downward slope in the 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 spot,
the control unit raises the auger by the raising and lowering mechanism.
4. The vehicle according to claim 1 , further comprising:
a rolling mechanism that rolls the auger,
wherein the control unit controls the rolling mechanism in accordance with the deformation of the predetermined pattern.
5. The vehicle according to claim 4 ,
wherein when the predetermined pattern deforms in accordance with a lateral inclination of the spot,
the control unit rolls the auger such that a rolling state of the auger matches an inclination of the lateral inclination.
6. The vehicle according to claim 1 ,
wherein when the predetermined pattern deforms in accordance with a level difference or a transition border of a downward slope in the spot,
the control unit decreases the travel speed to a low speed.
7. The vehicle according to claim 1 ,
wherein a light of the predetermined pattern is a visible light.
8. The vehicle according to claim 1 ,
wherein the predetermined pattern is grid-shaped.
