Abstract

A method of controlling a work machine is a method of controlling the work machine provided with a machine body that moves according to an operation device operation and that is capable of changing an operation pattern which is a correspondence between the operation device operation and the machine body movement. The control method has presenting the operation pattern information, which shows the current operation pattern, at the time of switching from a state in which the machine body fails to move according to the operation device operation to a state in which the machine body moves according to the operation device operation.

First claim

The invention claimed is:

1 . A method of controlling a work machine provided with a machine body that moves according to an operation device's operation and that is capable of changing an operation pattern which is a correspondence between the operation device's operation and the machine body's movement, the method of controlling comprising:
causing a display device to display a home screen including: information on an active state of the work machine and, operation pattern information showing the operation pattern that is current, wherein after the display device is turned on, a notification screen that includes the operation pattern information is displayed in the display device before the home screen.

2 . The method of controlling the work machine as claimed in claim 1 , wherein on the home screen, the information on the active state of the work machine and the operation pattern information are placed adjacent to each other.

3 . The method of controlling the work machine as claimed in claim 1 , wherein the home screen further includes a graphic image that shows information on a function of the work machine.

4 . The method of controlling the work machine as claimed in claim 3 , wherein on the home screen, the graphic image and the operation pattern are so placed as to be spaced apart.

5 . The method of controlling the work machine as claimed in claim 1 , wherein the home screen's region where at least a part of the information on the active state of the work machine is displayed is capable of displaying a peripheral image of the machine body.

6 . The method of controlling the work machine as claimed in claim 5 , wherein the operation pattern information is placed around the region of the home screen.

7 . The method of controlling the work machine as claimed in claim 1 , wherein whether or not to display the operation pattern information in the home screen is determined according to at least one of a specification and type of the work machine.

8 . The method of controlling the work machine as claimed in claim 7 , wherein when the work machine is free from a function to change the operation pattern, the operation pattern information is not displayed in the home screen.

9 . The method of controlling the work machine as claimed in claim 1 , wherein the operation pattern information on the home screen corresponds to a notation of a name plate attached to the machine body.

10 . A method of controlling a work machine provided with a machine body that moves according to an operation device's operation and that is capable of changing an operation pattern which is a correspondence between the operation device's operation and the machine body's movement, the method of controlling, comprising:
causing the display device to display a change screen for changing the operation pattern, and causing the display device to display a call up screen for calling up the change screen, wherein the call up screen includes operation pattern information showing the current operation pattern, wherein after the display device is turned on, a notification screen that includes the operation pattern information is displayed in the display device before a home screen.

11 . The method of controlling the work machine as claimed in claim 10 , wherein the call up screen includes a call up object that accepts an operation to call up the change screen, and the operation pattern information is displayed in association with the call up object.

12 . The method of controlling the work machine as claimed in claim 10 , wherein the change screen includes changed pattern information showing the operation pattern after the changing.

13 . The method of controlling the work machine as claimed in claim 12 , wherein the changed pattern information on the change screen corresponds to a notation of a name plate attached to the machine body.

14 . The method of controlling the work machine as claimed in claim 10 , wherein in a state in which the machine body moves according to the operation device's operation, the display device is caused to display the home screen, and
a display screen displayed at the display device shifts from the home screen via the call up screen, which is different from the home screen, to the change screen.

15 . The method of controlling the work machine as claimed in claim 10 , wherein the operation pattern is changeable only in the state in which the machine body fails to move according to the operation device's operation, out of the state in which the machine body fails to move according to the operation device's operation and the state in which the machine body moves according to the operation device's operation.

16 . The method of controlling the work machine as claimed in claim 15 , wherein switching between the state in which the machine body fails to move according to the operation device's operation and the state in which the machine body moves according to the operation device's operation is performed at least according to a cutoff lever's operation.

17 . A method of controlling a work machine provided with a machine body that moves according to an operation device's operation and that is capable of changing an operation pattern which is a correspondence between the operation device's operation and the machine body's movement, the method of controlling, comprising:
presenting the operation pattern information, which shows the current operation pattern, at the time of switching from a state in which the machine body fails to move according to the operation device's operation, and causing a display device to display a home screen, wherein after the display device is turned on, a notification screen that includes the operation pattern information is displayed in the display device before the home screen.

18 . The method of controlling the work machine as claimed in claim 17 , wherein the display device displays the home screen in a state in which the machine body moves according to the operation device's operation.

19 . The method of controlling the work machine as claimed in claim 18 , wherein the notification screen is displayed at the display device at the time of shift from a specific screen to the home screen.

20 . The method of controlling the work machine as claimed in claim 18 , wherein the notification screen, after occurring of a specific event related to an operation, is displayed at the display device before the displaying of the home screen.

21 . The method of controlling the work machine as claimed in claim 18 , wherein the home screen includes information on the active state of the work machine.

22 . The method of controlling the work machine as claimed in claim 18 , wherein the home screen includes the operation pattern information.

23 . The method of controlling the work machine as claimed in claim 18 , wherein the notification screen includes, as the operation pattern information, a graphic image that shows the correspondence between the operation device's operation and the machine body's movement.

24 . The method of controlling the work machine as claimed in claim 18 , wherein the operation pattern information in the notification screen corresponds to a notation of a name plate attached to the machine body.
