Control system, mobile object, and control method

1 . A control system configured to control movement of a mobile object that is configured to be conveyed by unmanned driving at least in a manufacturing process, the control system comprising:

a processor configured to include

a stop position identification section configured to identify a stop position at which the mobile object is stopped on a conveying part of a conveyance apparatus including the conveying part configured to convey the mobile object; and

a control command section configured to generate and output a control command to cause the mobile object to enter the conveying part according to the stop position,

wherein the stop position identification section is configured to:

identify a plurality of candidate stop positions corresponding to a plurality of wheel stops provided on the conveying part;

acquire obstacle information indicating presence or absence of an obstacle at each of the candidate stop positions; and

select the stop position among the plurality of candidate stop positions according to the presence or absence of the obstacle.

2 . The control system according to claim 1 , wherein the control command section is configured to generate and output a control command to control at least one of timing of causing the mobile object to enter the conveying part and a speed of the mobile object.

3 . The control system according to claim 2 , wherein when a distance between the conveyance start position at which the conveyance of the mobile object by the conveying part is started and the stop position is larger than a preset threshold value, the control command section is configured to generate and output a control command to cause the mobile object to enter the conveying part.

4 . The control system according to claim 2 , wherein when a distance between the conveyance start position at which the conveyance of the mobile object by the conveying part is started and the stop position is equal to or less than a preset threshold value, the control command section is configured to generate and output a control command to stop the mobile object for a preset time.

5 . The control system according to claim 1 , wherein the control command section is configured to generate and output a control command to stop movement of the mobile object depending on a state of the mobile object on the conveying part.

6 . The control system according to claim 1 , further comprising a conveyance control section configured to stop driving of the mobile object by the conveying part depending on a state of the mobile object on the conveying part.

7 . A control method that controls movement of a mobile object that is configured to be conveyed by unmanned driving at least in a manufacturing process, the control method comprising:

identifying a stop position at which the mobile object is stopped on a conveying part of a conveyance apparatus including the conveying part configured to convey the mobile object;

generating and outputting a control command to cause the mobile object to enter the conveying part according to the stop position;

wherein the identifying the stop position comprises:

identifying a plurality of candidate stop positions corresponding to a plurality of wheel stops provided on the conveying part;

acquiring obstacle information indicating presence or absence of an obstacle at each of the candidate stop positions; and

selecting the stop position among the plurality of candidate stop positions according to the presence or absence of the obstacle.

8 . A control system configured to control movement of a mobile object that is configured to be conveyed by unmanned driving at least in a manufacturing process, the control system comprising:

a processor configured to include

a stop position identification section configured to identify a stop position at which the mobile object is stopped on a conveying part of a conveyance apparatus including the conveying part configured to convey the mobile object; and

a control command section configured to generate and output a control command to cause the mobile object to enter the conveying part according to the stop position,

wherein the stop position identification section is configured to:

identify a plurality of candidate stop positions corresponding to a plurality of wheel stops provided on the conveying part;

acquire obstacle information indicating presence or absence of an obstacle at each of the candidate stop positions; and

select the stop position among the plurality of candidate stop positions according to the presence or absence of the obstacle, and

wherein the stop position identification section is configured to:

when no obstacle is present at any one of the candidate stop positions, identify, as the stop position, the candidate stop position that is located farthest from a conveyance start position where the conveyance of the mobile object by the conveying part is started, among the plurality of candidate stop positions, and

when the obstacle is present at any one of the candidate stop positions, identify, as the stop position, the candidate stop position located immediately before the candidate stop position at which the obstacle located closest to the conveyance start position is present as viewed from the conveyance start position, among the plurality of candidate stop positions.
