The vehicle display device 1 has a structure in which a plurality of cylindrical display segments 3 are connected in an axial direction by a flexible connecting member 4. The display control circuit 5 is connected to the display segment 3 at the end position. The display control circuit 5 includes signals from devices such as various sensors and a car navigation system (here, a position signal 6 of a preceding vehicle by a laser radar) and a signal for determining day or night (here, a vehicle side light lighting signal). 7).

Each of the display segment 3 and the connecting member 4 has a structure shown in FIGS. The base 9 to which an appropriate number, here four LEDs 8 are mounted, is accommodated inside the display unit 3. A long window in the axial direction is cut in a part of the side peripheral surface of the display unit, and a filter 1 for cutting unnecessary light out of light emitted from the internal LED 8 is provided in the window.
1 (for example, a louver filter) is attached.

It is to be noted that a small, inexpensive and relatively bright display is possible by using an LED as an indicator light, but instead, a small VF is used in accordance with the display contents of the present apparatus.
T or a film-type EL can be adopted, and a display element such as an SSD can also be used. Furthermore, a light emitting element such as a small incandescent lamp, a cold cathode tube, or a discharge lamp (neon lamp) can be employed.

A support member 1 is provided at both ends in the axial direction of the display segment 3.
2A (the one located on the left side of each display unit 3 in each figure) and 12B (the one located on the right side of each display unit 3 in each figure) are provided. This support member 12A,
Reference numeral 12B is for fixing the display unit 3 on the instrument panel 2. The support plate 13 rotatably supports the display unit 3 and the end plates 15A, 15B for accommodating the cam disks 14A, 14B. This is a two-sheet configuration. Support plate 13
By providing a ratchet gear mechanism between the display body 3 and the peripheral surface of the end of the display body 3, the display body 3 can be rotated by a desired angle in either the forward or reverse direction with respect to the support plate 13. It is.

As shown in FIG.
A and 14B are formed with cam holes 16A and 16B in which the distance from the circumference is reversed on the left and right, and the cam bars 17A and 17B at the left and right ends of the base 9 of the LED 8 penetrate therethrough. It is. The cam disks 14A and 14B can be exchanged according to the type of vehicle on which the present apparatus is mounted, that is, according to the curved shape of the windshield.

The means for fixing each display unit segment 3 to the instrument panel 2 is not particularly limited, but a magic tape can be employed as a simple method, and one of the magic tapes is attached to the bottom of each of the support members 12A and 12B. Attachment is performed by attaching the other side of the magic tape to a position to be fixed on the instrument panel 2. However, a method in which the support members 12A and 12B are fixed at appropriate positions on the instrument panel 2 with an adhesive or screwed may be employed.

Rotational position detecting contacts 20A and 20B are provided on one support plate 13A of each display unit 3 so that the display unit 3 is moved upward from the horizontal position shown in FIG. 3 to the upward position shown in FIG. By rotating to the position, both of them come into contact with a short-circuit contact (not shown) provided on the end plate 15A side to short-circuit, and this short-circuit is detected by a rotation angle detection circuit on the electric circuit side described later. Thus, it is determined that the display segment 3 is in the upward position.

Here, the connecting member 4 employs a bellows body made of a soft material such as rubber, and the electric wiring 19 is penetrated therein. As this material, a silicone rubber, a flexible synthetic resin, or a shape memory alloy can be used.

FIG. 9 shows the configuration of the electric circuit of the vehicle display device according to the present embodiment. FIG. 9 shows the display segment 3 as 4
Fig. 3 shows a circuit configuration in the case of continuous connection. Four LEDs 8 and a switching transistor 21 for turning on / off the LEDs simultaneously on a base 9 in each display unit 3 are connected in series between a power supply line 22 and a ground 23. The rotational position of the communication IC 25 for driving the switching transistor 21 on / off and the display segment 3, that is, the horizontal state (direct display) or the upward state (HU)
The above-described rotation angle detection circuit 24 for determining whether the display is of the D type) is provided. The communication IC 25 communicates with the control circuit 5 by a common communication line 26 in a multiplex communication system, receives a control signal from the control circuit 5, and performs on / off control of the switching transistor 21. Thus, there is an advantage that even if the number of connected display unit segments 3 is increased, only two systems of the power supply line 22 and the communication signal line 26 are required for the electric wiring 19 extending to the whole.

The communication IC 25 controls on / off of the switching transistor 21 and controls the amount of light emitted from the LED 8 by controlling the current flowing through the switching transistor 21. This control method will be described later.

In order to mount the vehicle display device 1 having the above-described structure to a vehicle, a required number of display segments 3 and connection members 4 are prepared, and the respective display segments 3 are connected to the upper surface of the instrument panel 2. The connecting member 4 is arranged along the curved shape of the windshield F / W, and each display segment 3 is fixed to the upper surface of the instrument panel 2 by supporting members 12A and 12B at both ends thereof. At the time of this mounting, the flexible display member 4 is divided into display segments 3 on both sides thereof.
Is adjusted according to the curved surface of the windshield F / W.

That is, the curved shape and inclination of the windshield F / W and the curved shape of the instrument panel 2 itself vary depending on the type of vehicle and the manufacturer, and the front position portion of the driver's seat is left-right asymmetric. Most are. Therefore, when the vehicular display device 1 of the present embodiment is used for displaying a preceding vehicle as a target to be followed by the following distance control device, the display device is set so that the HUD display is substantially horizontal when viewed from the driver. The connection angle of the segment 3 is adjusted, and the emission angle of light from the LED 8 is also adjusted.

In order to adjust the connection angle, a mounting position in consideration of the amount of bending of the device 1 is determined from CAD for each vehicle type, and the position is printed on translucent paper or film. And each indicator segment 3 is attached in accordance with the mark.

The light emission angle is adjusted by using a cam disk having an appropriate cam hole among a plurality of types of cam disks 14A and 14B having cam holes 16A and 16B corresponding to each vehicle type. Attach to plates 15A and 15B. As a result, the emission angle can be adjusted so that the display of the HUD system looks almost horizontal when viewed from the driver, as described later. Alternatively, the output angle adjusting mechanism may employ a mechanism using attractive repulsion by an electromagnet, a motor or manual rotation mechanism, or a mechanism using a spring. Instead of mechanical adjustment means, a vari-angle prism, a lens, or a reflecting mirror that optically adjusts each direction of emission may be used.

The electric wiring 19 between the display units 3 and 3 is connected inside the connecting member 4 as shown in FIGS. Thereby, the circuit configuration shown in FIG. 9 can be completed.

As described above, as shown in FIG. 1 and FIG. 2, the vehicle display device 1 of the present embodiment is arranged on the upper surface of the instrument panel 2 in front of the driver's seat with respect to the curved surface of the windshield F / W. And can be mounted in an appropriate arrangement.

Next, as shown in FIGS. 1 and 2, the operation of the vehicle display device 1 according to the present embodiment, which is mounted on an automobile, becomes a tracking target that automatically follows the inter-vehicle distance tracking control device. An example will be described in which the present invention is used as a follow-up target display device that displays which vehicle is ahead so that the driver at the driver's seat can recognize it at a glance. FIG. 1 shows a state in which the filter 11 of the display window of each display unit 3 of the vehicle display device 1 is turned sideways so as to face the driver's seat so that the driver at the driver's seat can directly see the display. ing. Figure 2 shows the windshield F
/ W, and shows a state in which the filter 11 of each display unit segment 3 is turned upward so as to be displayed in the HUD system.

The display control circuit 5 receives a position signal 6 from a following distance control device (not shown) indicating a position of a preceding vehicle as a follow target, and a discrimination signal for determining the brightness of the display. The vehicle side light lighting signal 7 to be used is input, and the display segment 3 (FIG. 9) at the corresponding position is input through the communication signal line 26 (passing through the electric wiring 19).
Assuming that the display segment 3-2 has been designated in (2), a lighting command signal is transmitted by designating a receiver as described below. In parallel with this, the display control circuit 5 controls the voltage of the power supply line 22 to be high during the day and low during the night by the day / night identification signal 7.

When the communication IC 25 of the display segment 3-2 receives the lighting command signal transmitted from the display control circuit 5 by designating its own circuit, the communication IC 25 considers the rotation angle detection signal from the rotation angle detection circuit 24. Then, the light emission amount of the LED 8 is determined, the switching transistor 21 is turned on, and the current flowing therethrough is controlled, so that the LED 8 emits light at a predetermined light emission amount.

The control of the light emission amount is as follows.

(1) When the rotation angle detection circuit 24 detects the upward state and the side-lamp lighting signal 7 is off (during daytime,
(Equivalent to the case of HUD display).

(2) When the rotation angle detection circuit 24 detects the upward state, and the vehicle side light lighting signal 7 is on (at night,
In the case of HUD display), the light is emitted second brightest.

(3) When the rotation angle detecting circuit 24 detects the lateral state and the sidelight lighting signal 7 is off (during daytime,
(Corresponding to the case of direct display).

(4) When the rotation angle detection circuit 24 detects a horizontal state and the vehicle side light lighting signal 7 is on (at night,
(Equivalent to direct display) is set to the smallest light emission amount.

As described above, in the HUD display, each display device is simply made substantially parallel to the curved surface of the windshield F / W due to the curved shape of the windshield F / W and due to the left-right asymmetry. Even if the split body 3 is attached, the preceding vehicle instruction cannot be displayed so as to be substantially linearly aligned in the horizontal direction. However, in the present embodiment, when the HUD display is performed for each vehicle type, that is, when the display unit 3 is turned upward, the rows of the LEDs 8 that are horizontally arranged in a straight line are displayed by the cam mechanism described above. By tilting the base 9 together, it is possible to display the preceding vehicle instruction so that the preceding vehicle instructions are arranged substantially in a straight line in the horizontal direction.

That is, as shown in FIGS. 7 (a) and 8 (a), when the filter 11 of the display segment 3 is in the horizontal direction (the direction of the driver's seat), the support members 12 on both sides are provided.
In A and 12B, the cam rods 17A and 17B are
Although located on the upper end side of 6A, 16B, the base 9 is aligned in the axial direction of the display unit body 3 in this state. And FIG.
As shown in FIG. 8B and FIG. 8B, when the indicator segment 3 is rotated upward so that the filter 11 of the indicator segment 3 faces upward, the cam rods 17A and 17B become the cam holes 16A and 16B.
The base 9 is located at the lower end side of the display unit 16B, and the base 9 is inclined with respect to the axial direction of the display unit body 3 on the A side (left side) and on the B side (right side) in the figure. Thereby, in the case of this example, the distance between the LED 8 at the left position and the windshield F / W is reduced, and the distance L at the right position is reduced.
The distance between the ED 8 and the front glass F / W is increased. Accordingly, when the curved surface of the windshield F / W is shaped to move away from the axial direction of the display segment 3 as going to the left, the shortest distance from each LED 8 to the windshield F / W becomes almost equal by this operation. HUD can be displayed in a horizontal straight line.

As described above, according to the first embodiment, an appropriate number of the display segments 3 are connected by the flexible connecting member 4, and the windshield F / W is mounted on the upper surface of the instrument panel 2. It is structured to fix each while adjusting the connection angle along the curved shape of
The vehicle can be mounted on the instrument panel so as to have a positional relationship capable of appropriately displaying the HUD with respect to a windshield of an automobile having different curved shapes depending on manufacturers. In addition, each display segment 3 can be viewed directly from the driver and the windshield F / F
Since it can rotate between the direction reflected in W,
It is possible to switch between the direct display and the HUD display according to the user's preference and the driving situation.

Furthermore, in this embodiment, the brightness of the display is automatically controlled according to the direction of the display unit 3 and the brightness of the surrounding environment at night / day.
Whether the display is a direct display or a HUD display, the display can be performed with a brightness that is easy to see.

Further, the display segment 3 is sequentially connected, and the communication ICs 25 are connected to the display control circuit 5 by one communication signal line 26.

However, when the route direction in the route guidance is displayed by an arrow, in the case of the HUD display, a mirror image reflected on the windshield is shown, and the directions of the straight and backward arrows are opposite to those of the direct display. Therefore, the control circuit 5
It is necessary to add a function of inverting the display unit for issuing the display instruction between the direct display and the HUD display in response to the straight-ahead instruction and the backward instruction output from the car navigation system.
