  However, it is difficult to instantaneously compare the current driving situation and the past driving situation by simply writing in parallel, and there is room for further improvement as a display expression of fuel consumption.

  Therefore, the present invention has been made paying attention to the above-described problem, and in a vehicle display device capable of displaying the fuel consumption of a vehicle, the user can instantaneously check the difference between the instantaneous fuel consumption and the average fuel consumption. It is an object of the present invention to provide a vehicle display device that can support the implementation of driving in consideration of the above.

  In order to solve the above problems, the present invention is a vehicle display device having at least a fuel consumption display unit that displays the fuel consumption of a vehicle, wherein the fuel consumption display unit indicates a single indicator unit and the indicator unit. And a bar graph that is arranged in accordance with the indicator portion and displays an average fuel consumption.

  In addition, the fuel consumption display unit includes a digital display unit capable of switching and displaying instantaneous fuel consumption and average fuel consumption.

  The display means may be a flat panel display, and the flat panel display may display the indicator part, the pointer, the bar graph, and the digital display part.

  The present invention relates to a display device for a vehicle that displays the fuel consumption of a vehicle as vehicle information. The user can instantly check the difference between the instantaneous fuel consumption and the average fuel consumption, and supports the implementation of driving considering the fuel consumption. It becomes possible.

  Embodiments to which the present invention is applied will be described below with reference to the accompanying drawings.

  The overall configuration of the vehicle display device will be described with reference to FIGS. 1 and 2. The vehicle display device is mainly composed of display means 1, vehicle information detection means 2, and control means 3.

  The display means 1 is composed of a flat panel display such as an LCD panel, an EL panel, or a plasma display. Moreover, the display means 1 comprises the fuel consumption display part mentioned later.

  The vehicle information detection means 2 detects vehicle information. In this embodiment, the vehicle information detection means 2 detects vehicle speed and fuel consumption as vehicle information so that at least the control means 3 calculates the instantaneous fuel consumption and the average fuel consumption. For example, it consists of a speed sensor and a vehicle side ECU (engine control unit).

  The control means 3 is composed of a microcomputer equipped with a CPU, ROM, RAM, an input / output interface and the like. The control means 3 receives the state signal from the vehicle information detection means 2, obtains measurement data of the vehicle information based on the state signal by a predetermined calculation process, and displays the drive signal corresponding to the measurement data at a predetermined cycle. 1 to drive the display means 1 for display. In the present embodiment, the control means 3 inputs each state signal indicating the vehicle speed and the fuel consumption from the vehicle information detection means 2, and based on the vehicle speed and the fuel consumption, the instantaneous fuel consumption and the average fuel consumption are obtained by a predetermined calculation process. The driving signal corresponding to the calculated result is output to the display unit 1 to display the instantaneous fuel consumption and the average fuel consumption on the display unit 1.

  The vehicle display device is configured by the above-described units. Next, the fuel consumption display part of the display means 1 in the vehicle display device will be described.

  FIG. 2 shows the fuel consumption display unit 11 of the display means 1. The fuel consumption display unit 11 includes an index unit 11a, a pointer unit 11b that instructs the indicator unit 11a to display the instantaneous fuel consumption in an analog manner, a bar graph 11c that also instructs the index unit 11a to display average fuel consumption, And a digital display section 11d that can switch and display the average fuel consumption. The indicator portion 11a, the pointer portion 11b, the bar graph 11c, and the digital display portion 11d are all display images displayed by the display means 1.

  The indicator unit 11a includes a plurality of indicators and serves as a common scale (scale) for indicating instantaneous fuel efficiency and average fuel efficiency.

  The pointer unit 11b is a display image that simulates a pointer in an analog instrument, and displays the instantaneous fuel consumption by instructing each of the indicators of the indicator unit 11a according to the change in the instantaneous fuel consumption and comparatively reading with the indicator unit 11a. Is.

  The bar graph 11c is arranged so as to overlap with the indicator portion 11a, and is for changing the length according to the change in each indicator average fuel consumption and displaying the average fuel consumption by comparison with the indicator portion 11a.

The digital display section 11d switches between instantaneous fuel efficiency and average fuel efficiency and displays them numerically. In FIG. 2, the average fuel consumption is displayed numerically on the digital display portion 11 d. The digital display section 11d can be switched to the instantaneous fuel consumption display as shown in FIG. 3 according to the driving situation and the user's preference.

  Such a vehicle display device displays an analog display of instantaneous fuel consumption by the pointer portion 11b and a bar graph display of average fuel consumption by the bar graph 11c by comparing and reading with a common indicator portion 11a, thereby indicating an index portion to be compared. Since 11a is single, the user can instantly check the difference between the instantaneous fuel consumption and the average fuel consumption as compared with the simple parallel display, and can support the implementation of driving considering the fuel consumption. It becomes. In addition, the instantaneous fuel consumption display, which is the current fuel consumption that varies greatly, is displayed as an analog display using the pointer portion 11b, and the bar graph 11c that displays the average fuel consumption is arranged so as to overlap the indicator portion 11a. An increase / decrease in the value of the fuel consumption can be instantly recognized by the behavior of the pointer portion 11b.

  In addition, by providing a digital display unit 11d for switching between instantaneous fuel consumption and average fuel consumption and displaying a number, information on information to be monitored carefully between instantaneous fuel consumption and average fuel consumption according to the situation and user's preference. Visibility can be further increased.

  In the present embodiment, the display unit 1 displays the indicator unit 11a, the pointer unit 11b, the bar graph 11c, and the digital display unit 11d as display images in the fuel consumption display unit 11. For example, the display unit 1 Even if it is the structure which arrange | positions the actual pointer | guide as a pointer | guide part in front of 1, the effect of this invention can fully be acquired.

The figure which shows the electrical constitution of the display apparatus for vehicles which is embodiment of this invention. The figure which shows the fuel consumption display part of the display apparatus for vehicles same as the above. The figure which shows the fuel consumption display part of the display apparatus for vehicles same as the above.
