Abstract

PURPOSE:To improve the relative visibility of a fixed display part and a movable display part, by performing respective displays so that the superposed part of the fixed and movable display parts is perfectly contained in the fixed display part when both display parts are superposed and a gap is present in both display parts even if the both display parts approach when not superposed. CONSTITUTION:The titled apparatus is constituted of a display means and a display control means. The display means is lighted by a predetermined display color and has a large number of display picture elements performing display and is arranged to the instrument board of a vehicle. The display control means controls the lighting of the display picture elements according to predetermined display data and generates a fixed display part as graduations and a movable display part as a moving indicator on the display means and sets the width of the fixed display part so as to make the same larger than that of the movable display part. The display movement control part of the display control part performs control so that the end edge parts of both display parts are not superposed and the superposed part is contained in the fixed display part in such a case that the superposed part with the fixed display part is generated when the movable display part moves while the end edge part of both display parts are not superposed when no superposed part is generated. The display color control part of the display control means performs control so that the display color of the superposed part of both display parts is different from that of the fixed display part.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a multiple display device for a vehicle that is installed in a vehicle's instrument panel and displays various information regarding the vehicle in the form of characters, figures, etc. The present invention relates to a multi-display device for a vehicle in which visibility of a fixed display section as a scale and a movable display section as a pointer is improved.

(Prior Art) In the instrument panel of a vehicle, in place of the conventional mechanical movable pointer, for example, as described in Japanese Utility Model Application Publication No. 56-89012, a fixed display as a scale drawn on the display surface has been used. Display devices are now available in which a large number of light-emitting segments are arranged along the line and a desired analog quantity is displayed by sequentially emitting light from these light-emitting segments.

Recently, using display surfaces made of EL elements, liquid crystals, etc.
BACKGROUND ART Multiple display devices that selectively display desired vehicle running information and alarm information on an instrument panel have been put into practical use.

In this case, various information is displayed by switching the display screen using a changeover switch.
The fixed display section as a scale on one display screen is displayed by a large number of display pixels on the display screen together with the movable display section as a pointer only when that screen is selected. In this case, unlike the case of the above-mentioned publication in which the pointer and the scale are provided independently of each other, when the display is controlled so that the pointer moves in a manner that overlaps the scale, the edge of the pointer and the scale Since there is a situation where the edges are close to each other or overlap with each other, there is a problem that the visibility at that time is extremely deteriorated.

(Object of the Invention) In view of the above-mentioned circumstances, an object of the present invention is to provide a multiple display device for a vehicle that improves the relative visibility of a fixed display section as a scale on a display surface and a movable display section as a pointer. With the goal.

(Structure of the Invention) As shown in FIG. 1, the present invention comprises a display means and a display control means. This display means has a large number of display pixels that are illuminated in a predetermined display color to generate a display, and is arranged on the instrument panel of the vehicle. The display control means controls the lighting of the display pixels according to predetermined display data to produce a fixed display section as a scale and a movable display section as a pointer that moves along the scale on the display means. and the width of the fixed display section in the moving direction of the movable display section is set to be larger than the width of the movable display section. Further, the display control means includes a display movement control section and a display color control section. When the movable display section and the fixed display section are overlapped when the movable display section is moved, the display movement control section is configured to prevent the edges of both display sections from overlapping each other and prevent the overlapping section from overlapping the movable display section and the fixed display section. is completely included in the fixed display section, and on the other hand, when the overlapping portion does not occur, the movable display section is controlled to move in such a manner that the edges of both display sections do not overlap. Further, the display color control section controls the display color of the overlapping portion of both display sections to be different from at least the display color of the fixed display section.

(Effect of the invention) With the above configuration, the edge of the movable display section as a pointer does not overlap the edge of the fixed display section as a scale, so even when both display sections are close to each other, there is no gap between the image display sections. If it is displayed as if it exists and both display parts are superimposed,
Since the superimposed part is displayed so as to be completely included in the fixed display part, the fixed display part does not appear to be missing, and the display color of the superimposed part is at least different from the display color of the fixed display part. Together, this has the advantage of improving visibility.

(Example) Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 2 shows the driver's seat of an automobile equipped with a display unit of a multiple display device according to the present invention, where 20 is a steering wheel, 21 is a steering wheel, and 22 is a display screen installed on the instrument panel 20. The display screen 22 includes a fixed display area 23 in which predetermined information is always displayed, and a multiple display '8! in which a plurality of display screens, for example, three types, are selectively displayed by operating a changeover switch!

The three types of display contents displayed in this multiple display area 24 are, for example, "tacho center display" centered on the tachometer;
These include the ``all item display'' and the ``safety monitor display,'' which display almost the same information as what is displayed on the instrument panel of a normal car. The third time shows the display screen 24a of "octopus center display".

Referring to FIG. 3, on the display screen 24a, an engine rotation needle, ie, a tachometer 25, and a torque split indicator 26, which indicates the state of power distribution to the front and rear wheels of a four-wheel drive system, are arranged. A pressure gauge 27, a water temperature gauge 28, and a fuel gauge 29 are arranged.

FIG. 4 shows a block diagram of the electronic circuit of the multiple display device according to the present invention. Reference numeral 31 denotes a controller, which calculates data input from each sensor and switch according to a control program, and also controls the operation of the display 32. Controller 3 consisting of a microcomputer that performs processing for
It has 3. Terminal ■ of the controller 31 is a power supply terminal connected to the buffer battery 34, terminals ■ to ■ are for fuel, turbocharging pressure,
This is an input terminal for data from each sensor that outputs data on engine rotation and vehicle speed, and terminal (2) is a terminal connected to the ignition switch. Also terminal
.about.[phase] are input terminals connected to switches for respectively selecting the above-mentioned three types of display contents displayed in the multiple display area 24 of FIG. In addition, terminals ~ [phase] are input terminals connected to each switch for warnings, such as insufficient brake fluid, poor charging, insufficient engine oil, abnormal exhaust pipe heat generation, insufficient cooling water, door ajar, tail lamp out, stop lamp. It is connected to a switch that is closed in each case of the seat belt breaking and the seat belt not being fastened. The output of the controller 33 is connected to the interface 35
The signal is output from the controller 31 via the signal line 36 and is applied to the interface 37 of the display 32 via the signal line 36. The output of this interface 37 is given to a driver 38, and a display section 39 is driven.

In the above configuration, when the switch connected to the terminal ■ of the controller 31 in FIG. 4 is selected, the tacho center display screen 24a as shown in FIG. 3 is displayed on the multiple display area 24 in FIG. be done. For example, on the fuel gauge 29 of the display screen 24a, a fixed scale 41 and a movable pointer 42 that moves along the X-axis (horizontal axis) are displayed in different colors.

5A to 5C are schematic explanatory diagrams of the moving operation of the movable pointer 42, and the pointer processing by the display movement control section is executed according to the flowchart of FIG. 6.

First, referring to FIG. 5A, the width of the movable pointer 42 in the moving direction (X-axis direction) on the display screen 24a is defined as one dot width of the display element, and two dots adjacent to each other in the X-axis direction
Set 0 1-dot width areas 1 to 10. The fixed scale 41 is displayed in areas 5 to 7 with a width of 3 dots, and the movable pointer 42
In the area where the fixed pointer 41 does not exist, control is performed such that the dot moves two dots at a time along the X axis in the manner: area l - area 3 = fti area 5.

In FIG. 6, the process advances to step S1 at every predetermined cycle, and the remaining amount of fuel is input in accordance with the output of the fuel sensor to the terminal (2) of the control section 31 in FIG. Guideline 4
2 is in FIG. 5A (11), the position to which the pointer 42 moves to the 0th order displayed on area 1 is area 3, but here, in step S2 of FIG. After performing position calculation, the positions of both edges of the scale 41 are read out in step S3.Then, the process proceeds to step S4, and the pointer 42 is read out.
It is determined whether the edge position of the scale 41 matches the edge position of the scale 41. If the determination result is No, that is, the guideline 4
If neither the front edge e1 nor the rear edge e2 coincide with the edges of the scales 4 and 1 with respect to the movement direction of the scale 2, the process proceeds to step S5, and the positions of both edges of the next scale are read out. Next, in step S6, it is determined whether all the scales have been read out or not.

If so, the process returns to step S4, and if YES, the process proceeds to step S7, where the pointer 42 is displayed in area 3 as shown in (2) of FIG. 5A.

The next position to which the pointer 42 moves is region 5 as shown by the broken line in (3) of FIG. 5A, but in this case, since the determination result in step S4 of FIG. Proceeding to step s8, it is determined whether or not the front edge e1 of the pointer 42 coincides with the edge of the scale 41. Guideline 4
2 moves to area 5, the rear edge e2 of the pointer 42 coincides with the edge of the scale 41, so the determination in step s8 is NO, and the process advances to step s9 to move the pointer 42 to 1.
A dot movement process is performed, and the pointer 42 is displayed in the area 6, that is, in the center position of the scale 41 in step s7.

In this case, the color of the overlapping portion 43 on the area 6 where the pointer 42 overlaps the scale 4I is set by the display color control unit to a display color that is at least different from the display color of the scale 41, preferably a color that is different from the display color of the scale 41.
and the pointer 42 are displayed in a different display color.

The next position to which the pointer 42 moves is region 8 as shown by the broken line in (4) of FIG. Proceeding to S8, it is determined whether or not the front edge e of the pointer 42 coincides with the edge of the scale 41. Guideline 42
Since the rear edge e2 of the pointer 42 is located at the edge of the scale 41 even when the pointer 42 moves to the area 8, the determination in step S8 is NO, and the process proceeds to step S9, where the pointer 42 is moved by one dot, and the pointer 42 is moved one dot. Move the pointer 42 to area 9 at S7.
to be displayed.

FIG. 5B shows a case in which the scale 41 is displayed at a position shifted one dot to the right from that in FIG. 5A, that is, in areas 6 to 8. In this case, (11 and (
The processing in step 2) is the same as steps (1) and (2) in FIG.
The front edge e of the pointer 42 coincides with the edge of the scale 41. Therefore, the determination in step S8 of FIG. 6 becomes YES, and the process moves to step S10, and (3) of FIG.
As shown in FIG. 3, the pointer 42 is moved by two dots, and the pointer 42 is displayed in area 7, that is, in the center of the scale 41 in step S7. In this case as well, a process is performed in which the display color of the overlapping portion 43 on the area 7 where the pointer 42 overlaps the scale 41 is displayed in a display color different from at least the display color of the scale 41.

The next position to which the pointer 42 moves is region 9 as shown by the broken line in (4) of FIG. 5B, but in this case also (
4), since the determination result in step S4 in FIG. 6 is YES and the determination result in step S8 is NO, the process proceeds to step S7 via step S9, and the pointer 42 is to be displayed.

FIG. 5C shows a case where the scale 41 is displayed in areas 5 to 8 having a width of four dots. In this case, the process until the pointer 42 reaches the area 6 where it overlaps the scale 41 as shown in (1) of FIG. 5C is the same as (11 and (2)) of FIG. The next movement position of the pointer 42 on the pointer 4 is
This is the area 8 where the front edge e1 of No. 2 coincides with the edge of the scale 41. Therefore, the determination results in step S4 and step S8 in FIG. 6 are both YES, and the process moves to step SIO, where the pointer 42 is moved by two dots as shown in (2) in FIG. 5C, and step S7 The pointer 42 is displayed in the area 10.

As is clear from the above description, according to the embodiment of the present invention, the pointer 42 is controlled to move so that the edge of the pointer 42 does not overlap the edge of the scale 41, and the pointer 42 is
When the overlapping portion 43 overlaps the scale 41, the display movement control unit controls the movement of the pointer 42 so that the overlapping portion 43 is completely included within the scale 41, and also changes the display color of the overlapping portion 43 between the scale 41 and the pointer. Since the display color control unit performs control to make the display color different from that of the pointer 42, the visibility of the pointer 42 can be significantly improved. In the embodiment, the width of the pointer 42 is set to 1 dot width, but it may be set to 2 dots wide, and even in that case, the scale is set to 4 dots wide, so that an overlapped portion occurs between the pointer and the scale. In such a case, the pointer should be controlled to move at 842 such that the edges of the pointer and the scale do not overlap and the overlapping portion is completely included within the scale.
