Display system for work vehicle having a display switching command device for switching a display in a display device
First Claim
1. A display system for a work vehicle comprising:
- a display device having an information display area;
a display control unit for controlling the display device for reading and displaying written and stored information;
a display switching command device which outputs a display switching command for switching a display in the display device;
a rotation sensor for detecting an output rotational speed of an engine; and
a key switch,wherein the display control unit selects and sets, based on an output from the display switching command device, one or more of an operating time display mode for displaying an operating time of an engine, an instantaneous fuel consumption display mode for displaying an instantaneous fuel consumption, an average fuel consumption display mode for displaying an average fuel consumption, and an amount of used fuel display mode for displaying an amount of used fuel, as a display mode for the information display area,wherein, when the display control unit is stopped by the key switch, a storing operation is performed to readably store a total operating time of the engine, the operating time of the engine after a reset thereof, the average fuel consumption or the average fuel consumption after a reset thereof, and the amount of used fuel or the amount of the fuel used after a reset thereof, which have been computed until the output rotational speed falls below to a second predetermined rotational speed; and
wherein, when the output rotational speed detected by the rotation sensor becomes greater than or equal to a first predetermined rotational speed and then an engine stall is determined by detecting the output rotational speed fallen below the second predetermined rotational speed, the storing operation is performed to readably store the total operating time of the engine, the operating time of the engine after a reset thereof, the average fuel consumption or the average fuel consumption after a reset thereof, and the amount of used fuel or the amount of the fuel used after a reset thereof, which have been computed until the output rotational speed falls below the second predetermined rotational speed.

Abstract
A display system for a work vehicle is disclosed including a display device (43) having an information display area (49), a display control unit (44) for controlling the display device, and a display switching command device (52A) which outputs a display switching command for switching a display in the display device. The display control unit (44) selects and sets, based on an output from the display switching command device (52A), one or more of an operating time display mode for displaying an operating time of an engine, an instantaneous fuel consumption display mode for displaying an instantaneous fuel consumption, an average fuel consumption display mode for displaying an average fuel consumption, and an amount of used fuel display mode for displaying an amount of used fuel, as a display mode for the information display area (49).
