VEHICLE STATUS NOTIFICATION DEVICE AND A VEHICLE STATUS NOTIFICATION METHOD FOR A CONSTRUCTION MACHINE
First Claim
1. A vehicle status notification device for a construction machine, comprising:
- a key switch connected to a battery;
an engine shut-off switch which is serially connected to a downstream side of the key switch in a connection line between the battery and an engine controller configured to control engine operation; and
a control unit configured to perform control to notify a notification unit that the engine shut-off switch is in an OFF state in a case that a signal at the downstream side of the engine shut-off switch is in the OFF state while a signal at an upstream side of the engine shut-off switch is in an ON state.

11. A vehicle status notification device for a construction machine, comprising:
-
a monitor controller configured to perform monitoring of operational status of the construction machine; one or more other controllers configured to output various data to the monitor controller, the controllers including an engine controller configured to control engine operation; a key switch connected to a battery; an engine shut-off switch which is serially connected to a downstream side of the key switch in a connection line between the battery and the engine controller; and a control unit configured to perform control to switch a display screen of a monitor to output that the engine shut-off switch is in an OFF state to the display screen in a case that a signal at the downstream side of the engine shut-off switch is in the OFF state while a signal at an upstream side of the engine shut-off switch is in an ON state, and to perform, in a case that the signal at the downstream side of the engine shut-off switch is in the OFF state, processing control to invalidate a process for abnormality detection which is to be performed when the signal at the downstream side of the engine shut-off switch is in the ON state.

12. A vehicle status notification method for a construction machine including a key switch connected to a battery and an engine shut-off switch which is serially connected to a downstream side of the key switch in a connection line between the battery and an engine controller to control engine operation, the method comprising:
performing control to notify a notification unit that the engine shut-off switch is in an OFF state in a case that a signal at the downstream side of the engine shut-off switch is in the OFF state while a signal at an upstream side of the engine shut-off switch is in an ON state. - View Dependent Claims (13)
