For example, it consists of a TA pulse, 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 state signals indicating the vehicle speed and the fuel consumption from the vehicle information detection means 2 to calculate the instantaneous fuel consumption and the average fuel consumption, and based on the vehicle speed and the fuel consumption, The average fuel consumption is obtained by a predetermined calculation process. And the drive signal according to a calculation result is output to the display means 1, and the instantaneous fuel consumption and average fuel consumption are displayed on the display means 1. FIG.

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

  FIG. 2 shows the rotation display unit 11 and the fuel consumption display unit 12 of the display means 1. The rotation display unit 11 includes a first indicator portion 11a and a first pointer portion 11b that indicates the first indicator portion 11a and displays the engine speed in an analog manner. The first indicator portion 11 a and the second pointer portion 11 b are all display images displayed by the display means 1.

  The first indicator portion 11a includes a plurality of indicators and serves as a scale (scale) for indicating the engine speed.

  The first pointer portion 11b is a display image that imitates a pointer in an analog instrument, rotates its display position in accordance with changes in engine speed, and indicates each indicator of the first indicator portion 11a. The engine speed is displayed by comparison with the first indicator portion 11a.

  The fuel consumption display unit 12 indicates the second indicator portion 12a, the second indicator portion 12b that indicates the second indicator portion 12a and displays the instantaneous fuel consumption in analog, and the second indicator portion 12a that also indicates the average. It has a bar graph 12c for displaying fuel consumption, and a digital display section 12d that can switch and display instantaneous fuel consumption and average fuel consumption. Further, the fuel consumption display unit 12 is displayed so as to be positioned inside the rotation display unit 11. The second indicator portion 12a, the second pointer portion 12b, the bar graph 12c, and the digital display portion 12d are all display images displayed by the display means 1.

  The second indicator unit 12a includes a plurality of indicators and serves as a common scale (scale) for indicating the instantaneous fuel efficiency and the average fuel efficiency.

  The second pointer portion 12b is a display image that imitates a pointer in an analog instrument, rotates its display position in accordance with a change in instantaneous fuel consumption, and indicates each indicator of the second indicator portion 12a. This is for displaying the instantaneous fuel consumption by comparative reading with the second indicator portion 12a. The first pointer portion 11b and the second pointer portion 12b are arranged so as to rotate on a concentric circle. That is, the first and second pointer portions 11b and 12b are arranged to have the same rotation center.

  The bar graph 12c is arranged so as to overlap with the second indicator portion 12a, the length thereof is changed in accordance with the change in the average fuel consumption, and the average fuel consumption is determined by comparison with the respective indicators of the second indicator portion 12a. It is for display.

  The digital display unit 12d switches between instantaneous fuel efficiency and average fuel efficiency and displays them numerically. In FIG. 2, the instantaneous fuel consumption is numerically displayed on the digital display portion 11 d.

  In FIG. 2, a case where the fuel consumption display unit 12 is displayed so as to be positioned inside the rotation display unit 11 is shown, but the display unit 1 includes the rotation display unit 11 and the fuel consumption display unit 12. The display position can be arbitrarily switched. That is, as shown in FIG. 3, it is possible to switch to a display mode in which the rotation display unit 11 is displayed so as to overlap the fuel consumption display unit 12.

  Such a vehicle display device displays an actual driving situation by displaying one of a rotation display unit 11 for analog display of engine speed and a fuel consumption display unit 12 for analog display of fuel consumption so as to be positioned inside the other. The user can visually recognize (in particular, the accelerator work that has a great influence on the quality of fuel consumption) and the fluctuations in the fuel consumption at a glance without moving the line of sight, and can support the implementation of driving considering the fuel consumption. Further, by arranging the first and second pointer portions 11b and 12b so as to rotate on concentric circles, the respective behaviors can be recognized at a glance.

  Further, the rotation display unit 11 and the fuel consumption display unit 12 are displayed by the display means 1, and the display position of the rotation display unit 11 and the fuel consumption display unit 12 can be arbitrarily switched, so that it can be changed according to the situation and user's preference. Therefore, it is possible to further improve the visibility of information to be monitored carefully between the engine speed and the fuel consumption.

  In the present embodiment, the display means 1 includes the first and second indicator portions 11a and 12a and the first and second pointer portions 11b and 12b as display images in the rotation display portion 11 and the fuel consumption display portion 12. However, for example, even if the structure is such that the actual pointer is arranged as the first and second pointer portions in front of the display means 1, the effect of the present invention can be sufficiently obtained.
