A display device (40) that displays information of a plurality of variables that reflect a state of a vehicle, the display device (40) including: a first meter image (41) including a first scale displaying (42) part that displays a scale of a first variable included in the plurality of variables and an indicating part (43) that indicates the first variable that varies with the state of the vehicle and rotating the first scale displaying part (42) in accordance with variation of the first variable, fixing the position of the indicating part (43); and a second meter image (44) including a second scale displaying part (45) that displays a scale of a second variable included in the plurality of variables and a displaying part (46) that displays the second variable that varies with the state of the vehicle, wherein the first meter image (41) and the second meter image (44) are adjacent to each other.

An in-vehicle control system is equipped in a vehicle, and includes an image drawer, a reproduction controller and a voltage detector. The image drawer draws a pictorial measuring instrument as an image representing a measuring instrument related to travelling of the vehicle. The vehicle includes an audiovisual information output device and a reproduction signal generator. The audiovisual information output device outputs audiovisual information for an occupant in the vehicle. The reproduction signal generator generates a reproduction signal for causing the audiovisual information output device to output the audiovisual information. The reproduction controller reproduces the audiovisual information, stops reproduction of the audiovisual information, resumes the reproduction of the audiovisual information from a stop position of the reproduction of the audiovisual information, and transmits an instruction to the reproduction signal generator for generating the reproduction signal. The voltage detector detects a value of a voltage of a battery equipped in the vehicle.

A fuel level measurement system and method for liquified natural gas (LNG) powered machines is disclosed. An engine control module (ECM) receives fuel line pressure levels at a first time (e.g., a key-off event) and, again, at a second time (e.g., a key-on event). The ECM predicts an expected change in pressure from the key-off event to the key-on event based on various factors. If the change in pressure detected is greater than a threshold level different from the predicted change in pressure, the ECM determines a fill event and resets a current fuel level. The ECM tracks mass flow commands used to provide fuel to the engine to determine the consumption of fuel from the fuel tank and to determine a new current fuel level based on the amount of fuel consumed. The current fuel level is displayed on a fuel gauge.

(Object) To provide an image control technology that enables an occupant of a moving body to recognize the difference between the present traveling speed and other speed related information, with good visibility. (Means of Achieving the object) An image control apparatus installed in a movable body, includes a controller configured to generate data of a display image in which a present moving speed of the movable body is indicated together with other speed related information, and change a display mode related to a difference between the present moving speed and a speed indicated by the other speed related information, upon detecting that a predetermined condition is satisfied.

A display system and a method for display control of a gauge graphic is provided. The display system controls the display device to display the gauge graphic. The gauge graphic includes a scale and a needle movable on the scale. The scale includes a first region and a second region. The display system detects a first movement of the needle beyond a first threshold marking on the scale and towards an end of the first region and controls the display device to gradually unmask a first gradation pattern in the second region based on the detected first movement. The display system further detects a second movement of the needle over the second region and controls the display device to change the unmasked first gradation pattern so that the unmasked first gradation pattern flashes with a defined frequency in the second region based on the detected second movement.

A gauge device is provided and includes an analog display to signify a measured valued, a motor and worm gear arrangement which is configured to retain a current state of the analog display when de-energized or to change the analog display when energized and a control system. The control system is configured to normally de-energize the motor and worm gear arrangement and to energize the motor and worm gear arrangement only in accordance with a calculated state of the analog display differing from the current state by at least a threshold level.

A work vehicle includes: a chassis; an operator cab carried by the chassis; at least one fluid reservoir carried by the chassis; at least one fluid sensor disposed in the at least one fluid reservoir and configured to output a fluid level signal corresponding to a level of fluid in the at least one fluid reservoir; and a fluid display gauge carried by the chassis outside of the operator cab and operatively coupled to the at least one fluid sensor, the fluid display gauge including an activation region that is accessible from the ground. The fluid display gauge is configured to display the level of fluid in the at least one fluid reservoir upon the activation region being activated.

A display system and a method for display control of a gauge graphic is provided. The display system controls the display device to display the gauge graphic. The gauge graphic includes a scale and a needle movable on the scale. The scale includes a first region and a second region. The display system detects a first movement of the needle beyond a first threshold marking on the scale and towards an end of the first region and controls the display device to gradually unmask a first gradation pattern in the second region based on the detected first movement. The display system further detects a second movement of the needle over the second region and controls the display device to change the unmasked first gradation pattern so that the unmasked first gradation pattern flashes with a defined frequency in the second region based on the detected second movement.

Provided are a vehicle instrument, a display method, and a vehicle speed monitoring display system. The vehicle instrument includes a display panel including an indicator structure used together with a scale on the dial for reading; a dial exposed by the display panel; and an actuating mechanism connected to the display panel and configured to control a movement of the display panel relative to the dial. The vehicle instrument has a first state, in which the display panel and the dial are in a first positional relationship, the display panel displays a first pattern region, and the first pattern region and the dial are in a second positional relationship; and a second state, in which the display panel and the dial are in a third positional relationship, the display panel displays the first pattern region, and the first pattern region and the dial are in the second positional relationship.
