Abstract

Provided are a traveling control system for a transport vehicle and a traveling control method for a transport vehicle capable of preventing unstable traveling when the transport vehicle travels while pulling a bogie. The traveling control system for a transport vehicle includes an imaging unit ( 3 ) provided corresponding to an operation region of a bogie ( 2 ) that travels together with a transport vehicle ( 1 ), a mode acquisition unit ( 14 ) configured to acquire a mode of the bogie based on an image including the bogie imaged by the imaging unit, and a mode determination unit ( 14 ) configured to determine a mode of the bogie based on the mode of the bogie acquired by the mode acquisition unit. Traveling of the transport vehicle is controlled based on a determination of the mode determination unit.

Claims (49)

1. A traveling control system for a transport vehicle that autonomously travels together with a bogie,

traveling of the transport vehicle being controlled according to a mode of the bogie that travels in an operation region, wherein

the operation region has a first region, a second region, and a third region, and

the third region is a region where the bogie is stopped, and

the traveling control system for a transport vehicle comprising:

an imaging unit provided corresponding to the third region of the operation region of the transport vehicle; and

circuitry is configured to acquire a mode of the bogie based on an image including the bogie imaged by the imaging unit.

2. The traveling control system for a transport vehicle according to claim 1 , wherein

a first characteristic unit is attached to the bogie, and

the circuitry is further configured to acquire the mode of the bogie based on an image including the first characteristic unit imaged by the imaging unit.

3. The traveling control system for a transport vehicle according to claim 2 , wherein the circuitry is further

configured to:

determine a mode of the bogie based on the acquired mode of the bogie, wherein

the traveling of the transport vehicle is controlled based on a determination of the circuitry.

4. The traveling control system for a transport vehicle according to claim 2 , wherein

a second characteristic unit is attached to the transport vehicle,

the circuitry is further configured to acquire a coupling mode of the transport vehicle to the bogie based on an image including the second characteristic unit imaged by the imaging unit, and

the traveling of the transport vehicle is controlled based on the coupling mode acquired by the circuitry.

5. The traveling control system for a transport vehicle according claim 2 , wherein

the operation region has a via-point through which the bogie passes, and

the imaging unit is provided corresponding to the via-point.

6. A traveling control system for a transport vehicle that autonomously travels together with a bogie, wherein

traveling of the transport vehicle is controlled according to a movement of the bogie that travels in an operation region, wherein

the operation region has a first region, a second region, and a third region, and

the third region is a region where the bogie is stopped.

7. The traveling control system for a transport vehicle according to claim 6 , comprising:

an imaging unit provided corresponding to an operation region of the bogie; and

a circuitry is further configured to acquire a movement of the bogie based on an image including the bogie imaged by the imaging unit.

8. The traveling control system for a transport vehicle according to claim 7 , wherein

a first characteristic unit is attached to the bogie, and

the circuitry is further configured to acquire the movement of the bogie based on an image including the first characteristic unit imaged by the imaging unit.

9. The traveling control system for a transport vehicle according to claim 7 , wherein the circuitry is further

configured to:

determine a traveling state of the bogie based on the acquired movement of the bogie, wherein

the traveling of the transport vehicle is controlled based on a determination of the circuitry.

10. The traveling control system for a transport vehicle according to claim 9 , wherein

the circuitry is further configured to determine whether the bogie is located inside a travel region having a predetermined width with reference to a travel route of the bogie that is preset in the operation region.

11. The traveling control system for a transport vehicle according to claim 7 , wherein

a second characteristic unit is attached to the transport vehicle,

the circuitry is further configured to acquire the movement of the transport vehicle based on an image including the second characteristic unit imaged by the imaging unit, and

the traveling of the transport vehicle is controlled based on the acquired movement of the transport vehicle.

12. The traveling control system for a transport vehicle according to claim 7 , wherein

the bogie travels along a virtual straight line in the first region and the bogie travels along a virtual curve in the second region, and

the imaging unit is further provided corresponding to the second region.

13. A traveling control method for a transport vehicle that autonomously travels together with a bogie, the method comprising:

controlling traveling of the transport vehicle according to a mode of the bogie that travels in an operation region, wherein

the operation region has a first region, a second region, and a third region, and

the third region is a region where the bogie is stopped; and

acquiring a mode of the bogie based on an image including the bogie imaged by an imaging unit, wherein the imaging unit is provided corresponding to the third region of the operation region.
