Display control system for a working vehicle
First Claim
1. A display control system for a working vehicle comprising:
- a plurality of sensors arranged on a vehicle body;
a display located on the vehicle body for displaying messages relating to various information;
a display controller operable in response to information from said sensors for selecting information to be displayed in said display, wherein said display controller has an ordinary display mode for displaying, on said display during an operation, information necessary to the operation, an adjusting mode for displaying, on said display during a non-operation time, information for correcting signals from said sensors, the information including messages for operations to be carried out by an operator wherein in said adjusting mode, messages for plural types of operations to be carried out by the operator are displayed in a predetermined order on said display, said messages being excluded after the operations are determined to have been carried out properly, based on signals from said sensors, said messages being displayed again when the operations are determined not to have been carried out properly, based on signals from said sensors, and a diagnostic mode for displaying, on said display during a non-operation time, information for checking the signals from said sensors, the information including messages related to the sensors diagnosed; and
a display mode selecting means for selecting one of said three display modes according a state of said working vehicle.

Abstract
A display control system for a working vehicle comprising a plurality of sensors arranged on a vehicle body, a display for displaying messages relating to various information, and a display controller operable in response to information from the sensors for selecting information to be displayed on the display. The display controller has an ordinary display mode for displaying, on the display during an operation, information necessary to the operation, an adjusting mode for displaying, on the display during a non-operating time, information for correcting signals from the sensors, and a diagnostic mode for displaying, on the display during a non-operating time, information for checking the signals from the sensors. The system includes a display mode selecting device for selecting one of the three display modes according to a state of the working vehicle.

3. The system as defined in claim 1, wherein, in said diagnostic mode, when a signal from one of said sensors diagnosed shows an abnormal value, a message indicating said one of said sensors diagnosed to be abnormal or a signal value from said one of said sensors is displayed on said display.
-
4. The system as defined in claim 1, wherein one of said adjusting mode and said diagnostic mode is selectable by operating an engine starting switch to a power supply position with a plurality of working switches turned on.
-
5. The system as defined in claim 1, wherein the display is located centrally on the vehicle body.
-
6. The system as defined in claim 5, wherein the display is located on a panel disposed forwardly of a steering wheel.

7. A display control system for a working vehicle comprising:
-
a plurality of sensors arranged on a vehicle body;
a display located on the vehicle body for displaying messages relating to various information;
a display controller operable in response to information from said sensors for selecting information to be displayed in said display, wherein said display controller has an ordinary display mode for displaying, on said display during an operation, information necessary to the operation, an adjusting mode for displaying, on said display during a non-operation time, information for correcting signals from said sensors, the information including messages for operations to be carried out by an operator, and a diagnostic mode for displaying on said display during a non-operation time, information for checking the signals from said sensors, the information including messages related to the sensors diagnosed, wherein in said diagnostic mode, when a signal from one of said sensors diagnosed shows an abnormal value, a message indicating said one of said sensors to be abnormal or a signal value from one of said sensors is displayed on said display; and
a display mode selecting means for selecting one of said three display modes according a state of said working vehicle. - View Dependent Claims (8, 9, 10, 11)
in said ordinary display mode, at least one of remaining fuel information and engine cooling water temperature information is displayed as a standard display on said display; and
when said sensors detect an abnormality in time of said standard display, said standard display is overridden by messages corresponding to said abnormality to be displayed as an alarm display on said display.
