Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicular display device having a display device for displaying vehicle information by numbers.

[0002]

[Problems to be solved by conventional techniques and devices]

 Currently, there is a digital type display device for displaying the vehicle speed, the engine speed, etc. in numerical form in the instruments installed in the vehicle. Usually, a small display portion for displaying a number is formed by 7 segments, and several small digits are provided for each display target to form one display portion.

When the ignition switch is turned on, each display unit lights up all the segments for a predetermined time in order to check the segments.

At present, however, there is a tendency for a car with a high-class feeling to be sought, and for this reason, vehicle manufacturers are trying to improve the interior design, and the display device used for a vehicle instrument is an exception. is not. Although the above-mentioned segment checking method fulfills its function sufficiently, it is hard to say that it contributes to the creation of a car that is too mechanical, monotonous, and high-class.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention displays these segments in a predetermined order when performing a segment check of a display device that displays vehicle information by segment. The predetermined order is to display the display section, which is usually composed of several segments of several digits provided for each display target such as vehicle speed and engine speed, in a predetermined order, or is composed of seven segments. That is, the small display part for displaying one number is displayed in a predetermined order, or each of the segments is displayed in a predetermined order, or in a combination thereof.

[0006]

【Example】

 An embodiment of the present invention is shown in FIGS. 1 to 13 and described. 1 to 5 show a first embodiment of the present application. In this embodiment, the engine speed, vehicle speed, and mileage are numerically displayed as segments to be displayed. Black smoked glass (not shown) is installed on the front of the instrument. For this reason, characters and scales cannot be seen unless the display device inside the instrument displays them.

FIGS. 1 to 4 show the state of the segment check performed after the ignition switch is turned on over time. First, a 4-digit small display section 11, 12, 13, 14 for displaying the engine speed. All the segments of the display unit 1 composed of are displayed (Fig. 1), and then all the segments of the display unit 2 composed of the three-digit small display units 21, 22, and 23 for displaying the vehicle speed ( 2) In addition, all segments of the display unit 3 composed of four-digit small display units 31, 32, 33, 34 for displaying the traveling distance are sequentially displayed (FIG. 3).

After the numerical display is finished, the bar graph 4 and the light emitting pointer 5 serving as a scale are displayed and turned on to further indicate the engine speed and the vehicle speed by the analog meter (FIG. 4).

The display order can be designated by the simple circuit shown in FIG. 5 and a program stored in the CPU 7 which is a processing circuit configured therein. When the ignition switch 6 is turned on, the display program in the CPU 7 is started. The program causes the drive circuit 81 for driving the display unit 1 to output a signal for displaying all the segments of the display unit 1, and after a predetermined time has elapsed, the display unit 2, the display unit 3, the burglar 4, and the light emission. The flow is such that the signal for driving the pointer 5 is output to the drive circuits 81, 82, 83, 84. The display of the segments excluding the bar graph 4 is performed for a predetermined time determined by the CPU 7. After the elapse of a predetermined time, each measured value is displayed according to the signal amount of the sensor (not shown) provided for each display target.

6 to 12 illustrate a second embodiment of the present application. Only parts different from those of the first embodiment will be described, and the same parts and those having the same functions are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, the display order of the small display section is determined. When the ignition switch is turned on, all segments of the leftmost small display section 11 of the display section 1 are displayed (Fig. 6), and after a predetermined time elapses. All the remaining small display sections 12, 13 and 14 of the display section 1 are simultaneously displayed (Fig. 7). Next, the leftmost small display section 21 of the display section 2 is displayed (FIG. 8), and then the remaining small display sections 22 and 23 are displayed (FIG. 9). The same applies to the display unit 3 (FIGS. 10 and 11). After the numerical display is completed, the bar graph 4 and the light emitting finger 5 are displayed as in the above embodiment (FIG. 12). The circuits for instructing the display order are the same as those in the first embodiment, and only the program is changed.

The small display section is displayed in the order of the small display section 11 → 12 → 13 → 14 → 21 → 22 → 23 → 31 → 32 → 33 → 34 → bar graph and light emitting pointers. Can also be considered.

Next, a third embodiment of the present application will be described. In this embodiment, each segment that constitutes each small display portion is displayed in a predetermined order. For the sake of explanation, the seven segments shown in FIG. 13 are labeled with (1), (2), (3), (4), (5), (6), and (7), and the ignition switch turns on. First, of the segments forming the leftmost small display portion 11 of the display portion 1, the central segment 11 (1) is displayed first, and then the segments 11 (2) → 11 (7) → 12 (1) → ・ ・・ → 12 (7) → 13 (1) → ・ ・ ・ → 13 (7) → 14 (1) → ・ ・ ・ → 14 (7) → 21 (1) → ・ ・ ・ → 23 (7) → 31 (1) → ・ ・ ・ 31 (7) → ・ ・ ・ → 34 (1) → ・ ・ ・ → 34 (7) Each segment is displayed as if drawing a small letter e of the alphabet.

Next, a fourth embodiment, which is a folding type of the first embodiment and the third embodiment, will be described. In this embodiment, the central segments 11 (1), 21 (1), 31 (1) of the leftmost small display portions 11, 21, 31 of the display portions 1, 2, 3 are displayed after the ignition switch is turned on. , Sequential segment 11 (2), 21 (2), 31 (2) → ・ ・ ・ → 11 (7), 21 (7), 31 (7) → 12 (1), 22 (1), 32 (1 ) → ・ ・ ・ → 12 (7), 22 (7), 32 (7) → ・ ・ ・ → 13 (7), 23 (7), 33 (7) → 14 (1), 34 (1) → .. .. → 14 (7), 34 (7) are displayed in this order so that each segment draws the letter e in each display section.

Further, as an application of the fourth embodiment, a type in which all small display portions are displayed so as to draw the letter e may be considered.

It should be noted that, in the above-mentioned embodiments, although a fuel gauge, a thermometer, a clock, a warning for displaying a character, a picture, and the like are not described in order to simplify the explanation, these are used. In this case, it is natural to use multiple segments or bar graphs to display the measured amount by the number or the amount of segments, so it is easy to check with the above method when checking these segments. It is a thing.

In the second embodiment, the leftmost small display portions 11, 21, 31 of the display portions 1, 2, 3 are displayed, and in the third embodiment, each segment is displayed so as to draw e. However, the order is not limited to this and can be changed appropriately.

Further, since smoke glass is used on the front surface of the instrument used in this description, there is no mention of a backlight for illuminating the instrument, illumination by ultraviolet rays, etc. If necessary, the lighting means may be turned on after the display of all the segments or before the display.
