Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle multiple display device capable of selectively displaying a plurality of display screens (displays) using a high resolution display device.

(Prior Art) In recent years, various kinds of information are selectively displayed on a display screen of a display device arranged on an instrument panel in front of a driver's seat of a vehicle so that a display area is organized and visibility is improved. Multiple display devices are being put to practical use.

By the way, the conventional display device 1 as shown in FIG.
In the case of displaying a tachometer or a speedometer, a movable display unit (a movable display unit that moves in response to a detection signal from the rotation sensor or the speed sensor with respect to a semi-circular fixed display unit 3 with scaled rotation values or speed values) is displayed. Pointer 2 is fixed display 3
Is moved about the center of rotation (see JP-A-57-139614).

Therefore, since it is necessary to secure the display area of the semi-circular fixed display unit 3 in the display device 1, the size of the tachometer and the speedometer is limited, visibility is reduced, and design flexibility is also reduced. There was a problem.

(Object of the Invention) The present invention has been made in order to solve the above-mentioned conventional problems, and it is possible to improve the visibility and the degree of freedom in design by modifying the shape control of the fixed display unit and the movable display unit. It has a basic purpose.

(Structure of the Invention) Therefore, the present invention provides a display means for displaying a figure or a character by a combination of a plurality of display pixels, a fixed display portion displayed on the display means, and an information detection means for detecting vehicle traveling information. A linear movable display unit that moves according to a detection signal from the storage unit, a storage unit that stores the track of the fixed display unit, and a calculation unit that calculates the position on the track of the fixed display unit corresponding to the detection signal. In addition, the movable display unit is configured to include a control unit that moves one end of the movable display unit along the fixed display unit so as to position the movable display unit at a position according to the calculation result of the calculation unit.

(Effect of the Invention) According to the present invention, even if the fixed display portion is elliptical or curved, one end of the movable display portion is moved along the fixed display portion. Since the display itself can be enlarged without securing a large display area like the fixed display part of, the visibility is improved and the shape of the fixed display part can be freely designed, and the degree of freedom in design is also increased. It will improve.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

The rotation speed (tacho) detection signal TACHO and the vehicle speed detection signal SP are input.

Further, steering information is input by the four-wheel steering control box 16 and torque information is input by the torque control box 17.

Further, the brake fluid level detection signal BRAKE, the charge detection signal CHARGE, the oil level detection signal OIL-L, the exhaust pipe abnormality detection signal HEAT, the cooling water level detection signal COOLANT, and the half door detection signal D are detected by the respective sensors.
OOR, tail lamp burnout detection signal TAIL, stop lamp burnout detection signal STOP, seat belt wearing detection signal BELT, washer fluid level detection signal WASHER
Are input respectively.

With respect to the EL controller 15, an interface 18 that outputs a request signal RQ to the four-wheel steering control box 16 and inputs a data signal DATA and the display device 13 of the display device 23 are detected by the sensors. An interface 19 for outputting vehicle traveling information is provided, and the octopus center screen changeover switch 20, all item screen changeover switch 21, and safety monitor screen changeover switch 22 are provided.

On the other hand, for the display device (EL display) 13 of the display device 23, an interface 24 for inputting vehicle traveling information output from the interface 19 of the control device 14 and an EL driver for driving the display device 13. 25, and a liquid crystal (L) for driving a liquid crystal (LCD) shutter 26 that is superposed at a proper position of the display device 13 with respect to the interface 24.
A CD) 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.

The liquid crystal display 30 is an LCD for displaying the AT position in an AT vehicle, that is, parking P, reverse R, neutral N, drive D, speed change 1, speed change 2, overdrive, trip, etc., by switching the rotary switch 33. Driver and controller 3
Driven by two. Reference numeral 35 is a trip reset switch.

In addition, the indicator 31 indicates the running state, that is, the sports I SPORTS-I, the sports II SPORT.
S-II, Touring Touring, City CIT
Y and lamp state, ie high beam HI-BEA
M, low beam LO-BEAM, auto AUTO,
The fog FOG is displayed as a lamp by switching the switch 34.

As shown in FIG. 1, on the display device 13, the octopus center screen is selected and displayed among the three basic screens described above.
On the tacho center screen, a tachometer 40, a torque split display portion 41, a turbo meter 42, a cooling water temperature meter 4 are provided.
3, the fuel meter 44 is displayed respectively.

Tachometer 40, torque split display 41, turbo meter 42, cooling water temperature meter 43, fuel meter 44
Are all fixed display parts 40a to 44a having scales.
And movable display portions (pointers) 40b to 44b which are moved by sequentially and continuously changing the lighting of the display pixels in accordance with the detection signal from the sensor, and the display portions 40a to 44a, 40b. 44b is displayed in a yellow display color against a black background color, for example.

The tachometer 40 has a curved fixed display portion 40a.
And a movable display section (pointer) 4 which rotates around the fulcrum 40c
0b, and the movable display section 40b rotates according to the rotation speed (octopus) detection signal TACHO by the sensor.

The curve of the fixed display section 40a is predetermined,
Therefore, the length from the fulcrum 40c of the movable display portion 40b along the fixed display portion 40a can be obtained in advance for the rotation angle of the movable display portion 40b.

For example, at a rotation angle of 0 ° the length l ₁ and at an angle of 40 ° the length l ₁ .
l ₂ , length l _{3 at} an angle of 100 °, length l ₄ at an angle of 140 °
Is.

Therefore, the detection signal is processed by the EC controller 15 of the control device 14, and in the display device 13 of the display device 23, the length l ₁ to the movable display portion 40b corresponding to the rotation angle in accordance with the input signal from the sensor. Change l ₄ .

As a result, the movable display section 40b rotates along the curved fixed display section 40a.

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

FIG. 4 shows an operation flow in the EL controller 15 of the control device 14 and the EL driver 25 of the display device 23, starting in step S1, reading the sensor value (detection signal) in step S2, and reading the sensor value in step S3. The rotation angle of the movable display unit 40b is calculated from the rotation angle, the length of the movable display unit 40b is calculated from the rotation angle in Step S4, and the movable display unit 40b having the length corresponding to the rotation angle is displayed on the tachometer 40 in Step S5. Then, the process returns from step S6 to step S1 and is repeated.
