Abstract

PURPOSE:To improve a visibility and a freedom in the design of a fixed display portion by enabling the length of a movable display portion to be changed along the fixed display portion even when the fixed portion is ellipsewise or curvewise. CONSTITUTION:A display device 13 displays figures and letters by the combination of a plurality of display picture elements. A controller changes the lengths l1-l4 of a movable display portion 40b for detecting a vehicle running information such that the lengths l1-l4 are displaced along fixed display portion 40a displayed in the device 13. The display portion 40b is rotated in response to a tachometer detecting signal TACHO from a sensor. The curve of display portion 40a is determined in advance and therefore the lengths l1-l4 of the display portion 40b measured from the fulcrum 40c thereof and changed along the display portion 40a can be obtained in advance for the rotary angles (for example, 40 deg.-140 deg.) of the display portion 40b. That is, the detecting signals are processed by the EC controller of a controller and the lengths l1-l4 of the display portion 40b are changed for the rotary angles in response to the input signal from the sensor in device 13.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a multiple display device for a vehicle that can selectively display a plurality of display screens (displays) using a high-resolution display device.

(Prior art) In recent years, various pieces of information have been selectively displayed on the display screen of a display device placed in front of the driver's seat of a vehicle, thereby organizing the display area and improving visibility. Such multiple display (multi-display) devices are being put into practical use.

By the way, the conventional display device 1 as shown in FIG.
When displaying the tachometer or speedometer, a movable display part that moves in response to detection signals from the rotation sensor and speed sensor is used, in contrast to the semicircular fixed display part 3 that scales rotation and speed values. (Pointer) 2 is the fixed display part 3
It moves around the center point of (
(See Japanese Patent Application Laid-Open No. 139614/1983).

Therefore, it is necessary to secure the display area of the semicircular fixed display section 3 on the display device l, which limits the size of the tachometer and speedometer, reducing visibility and reducing the degree of freedom in design. There was a problem.

(Object of the Invention) The present invention has been made to solve the above-mentioned conventional problems, and aims to improve visibility and design freedom by adding ingenuity to the shape control of the fixed display section and the movable display section. This is the main purpose of the study.

(Structure of the Invention) For this reason, the present invention detects vehicle running information with respect to a display means that displays figures and characters by matching the current number of display pixels, and a fixed display section displayed on the display means. and control means for changing the length of the movable display section so as to move along the fixed display section in response to a signal from the information detection means.

(Effects of the Invention) According to the present invention, even if the fixed display part is elliptical or curved, the length of the movable display part is changed by t[+ from that of the fixed display part. It does not require a large display area like a semicircular fixed display (but the display itself can be made larger, so visibility is improved and
You can freely design the shape of the fixed display section, increasing the degree of freedom in design.

I come to do it.

Each is done manually.

For the EL controller 15, there is an interface 18 which outputs a request signal RQ to the four-wheel steering control box 16 and manually inputs the data signal DATA.
The display device 13 of the display device 23 is provided with an ink face 19 that outputs the vehicle running information detected by each of the sensors. 21. A safety monitor screen changeover switch 22 is provided.

On the other hand, for the display device (EL display) 13 of the display device 23, there is an interface 24 that manually inputs vehicle running information output from the ink face 19 of the control device 14, and an EL driver that drives the display device 13. 25, and for the interface 24, a liquid crystal (LCD) for driving a liquid crystal (LCD) shutter 26 superimposed on a suitable position of the display device 13 is provided.
LCD) driver 27 is provided.

A liquid crystal (LCD) display 30 and an indicator 31 are provided around the display device 13 of the display device 23.

By switching the rotary switch 3.3, the liquid crystal display 30 displays the AT functions in an AT vehicle, namely baking P, reverse R, neutral N, drive D, and shifting 1. LCD driver/controller 3 to display gear shift 2, overdrive, trip, etc.

As shown in FIG. 1, the tacho center screen is selectively displayed on the display device 13 among the three basic screens mentioned above.
The tachometer center screen includes a tachometer 40, a torque split display section 41. Turbometer 12. Cooling water temperature meter 4
3. Fuel meter 44h (each displayed.

The above tachometer 40. Torque split display section 41, turbo meter 42. Cooling water temperature meter 43° Fuel meter 14
are fixed display sections 40a to 44a having scales.
and movable display parts (finger sticks) 40b to 44b that are moved by sequentially and continuously changing the lighting of display pixels according to detection signals from sensors, and each display part 40a to 44a, 40b .about.44b should be displayed, for example, in a yellow display color with χ·r on a black background color.

The tachometer 404, curved fixed display section 40a
and rotates around the fulcrum 40c by 4" movable display (pointer)
=10b, and the movable display section 40b is
It begins to rotate in response to the rotational speed (tacho) detection signal TACIIO from the sensor.

The curve of the fixed display section 10a is predetermined, and the fulcrum 40c of the movable display section 10b follows the fixed display section 40a as the movable display section 10b rotates ff degrees. The length from can be determined in advance.

For example, at a rotation angle of O0, the length is Ql, at an angle of 40 degrees, the length is Q, and at a rotation angle of 1'71 degrees, the length is Q8. angle 1
- At 10°, the length is Q4.

Therefore, the EC controller 15 of the control device 14 processes the detection signal, and in the display device 13 of the display device 23, the length Q1 of the movable display portion 40b is adjusted according to the rotation angle according to the human horn signal from the sensor. It will change Q4.

This allows the movable display section 40b to rotate along the curved fixed display section 40a.

FIG. 2 shows an example adapted to a speedometer 45, in which, like the tachometer 40, an elliptical fixed display section 45a and a movable display section (pointer) 45b rotating around a fulcrum 45c are shown.
The movable display section 45b rotates in response to a speed detection signal SP from a sensor. Note that the structure for changing the length of the movable display portion 45b in accordance with the rotation angle is the same as that of the tachometer 40 described above.

FIG. 4 shows the operation flow of the EL controller 15 of the control device 14 and the EL driver 25 of the display device 23. It starts in step S1, reads the sensor value (detection signal) in step S2, and reads the sensor value (detection signal) in step S3. 171 degrees of rotation of the movable display section 40b is calculated from
In step S4, the length of the movable display section 40b is calculated from the rotation angle, and in step S5, the length of the movable display section 40b corresponding to the rotation angle is displayed on the tachometer 40, and in step S6
Then return to step Sl and repeat this.
