Abstract

A shovel including a lower-part traveling body, an upper-part swiveling body which is enabled to swivel and is mounted to the lower-part traveling body, an actuator, and a control device that implements a first control process that causes the actuator to act autonomously, and a second control process that causes the actuator to act autonomously, wherein the control device is configured to select one control unit from among a plurality of control units that implements the first control process and the second control process, as a priority control process that is given priority to act, in a case where a conflict is judged to occur among the plurality of control units that implements the first control process and the second control process.

First claim

What is claimed is:

1 . A shovel comprising:
a lower-part traveling body; an upper-part swiveling body which is enabled to swivel and is mounted to the lower-part traveling body; an actuator; and a control device that implements a first control process that causes the actuator to act autonomously, and a second control process that causes the actuator to act autonomously, wherein the control device is configured to select one control unit from among a plurality of control units that implements the first control process and the second control process, as a priority control process that is given priority to act, in a case where a conflict is judged to occur among the plurality of control units that implements the first control process and the second control process.

2 . The shovel according to claim 1 ,
wherein the control device is configured to select the one control unit from among the plurality of control units that implements the first control process and the second control process, as the priority control unit, based on a priority order preset for each of the plurality of control units in the case where the conflict is judged to occur between the first control process and the second control process.

3 . The shovel according to claim 1 ,
wherein the control device is configured to select the one control unit from among the plurality of control units that implements the first control process and the second control process, as implementing the priority control process, based on a priority order preset for each object comes in contact with the shovel, in the case where the conflict is judged to occur between the first control process and the second control process.

4 . The shovel according to claim 1 ,
wherein the control device is configured to select a third control process that is different from both of the first control process and the second control process, as the priority control process, in the case where the conflict is judged to occur between the first control process and the second control process.

5 . A work system that supports a work by a shovel, the shovel which includes a lower-part traveling body, an upper-part swiveling body which is enabled to swivel and is mounted to the lower-part traveling body, an attachment which is mounted to the upper-part swiveling body; an end attachment which constitutes the attachment, and an actuator, the work system comprising:
a communication device configured to communicate with the shovel; and a control device that implements a first control process to cause the actuator of the shovel to act autonomously and a second control process to cause the actuator to act autonomously, wherein the control device is configured to select one control unit from among a plurality of control units that implements the first control process and the second control process, as a priority control process that is given priority to act, in a case where a conflict is judged to occur among the plurality of control units that implements the first control process and the second control process.

6 . The work system according to claim 5 ,
wherein the control device is configured to select the one control unit from among the plurality of control units that implements the first control process and the second control process, as the priority control process, based on a priority order preset for each of the plurality of control units in the case where the conflict is judged to occur between the first control process and the second control process.

7 . The work system according to claim 5 ,
wherein the control device is configured to select the one control unit from among the plurality of control units that implements the first control process and the second control process, as the priority control process, based on a priority order preset for each object comes in contact with the shovel, in the case where the conflict is judged to occur between the first control process and the second control process.

8 . The work system according to claim 5 ,
wherein the control device is configured to select a third control process that is different from both of the first control process and the second control process, as the priority control process, in the case where the conflict is judged to occur between the first control process and the second control process.
