Description

  The present invention belongs to the technical field of an in-vehicle display device that displays information of a plurality of devices mounted on a vehicle. More specifically, the information display unit and the operation unit are arranged at independent positions, and the respective display roles are clarified. The present invention relates to an in-vehicle display device.

  Conventionally, vehicles have various devices for enhancing the driving environment, such as audio devices (radio, cassette tape, CD, MD, DVD, etc.), car navigation devices, external information acquisition devices, and speed as travel control information. A meter, a fuel gauge, a water temperature gauge, and the like are mounted, and an in-vehicle display device that displays information from such various mounted devices as necessary is installed.

As such a display device, a multi-display device is widely used in practical use.
This multi-display device not only displays vehicle-equipped equipment information, but also displays a virtual switch on the display screen and touches the virtual switch to select and set the corresponding on-vehicle equipment. This is a so-called touch panel display capable of displaying the operation content and result on the screen. In other words, display of vehicle-mounted equipment information (map information, travel control information), selection setting operation to switch to desired vehicle-mounted equipment information and operation operation of vehicle-mounted equipment (air conditioner, audio, etc.) This is done on one screen.
However, in the multi-display device as described above, the driver needs to reach out to the display screen and touch the virtual switch while driving, in order to appropriately switch and display information on the desired on-vehicle equipment on the screen. There is. At that time, the driver once removes the viewpoint of recognition of the road condition ahead and shifts the viewpoint onto the screen, and there is a concern about accidents due to carelessness ahead.

In view of the above-mentioned problems, the following Patent Document 1 includes a display unit 70 that displays information related to a vehicle-mounted device, and an operation unit that operates information displayed on the display unit 70, as shown in FIGS. 7A and 7B. The setting operation screen 72 displayed on the display unit 70 is selected and set by pressing the pointing unit of the operation unit 71, and appropriately switched to the information on the desired on-vehicle equipment. A configuration that can be displayed is disclosed. Further, the operation unit 71 is detachably installed on the vehicle.

  In the invention of the above-mentioned Patent Document 1, the display unit 70 and the operation unit 71 are arranged at independent positions, and information relating to the on-vehicle equipment required can be freely switched and displayed by a simple pointing means for operation. It is recognized that the driver's viewpoint movement can be reduced during setting and selection.

  However, the pointing unit of the operation unit 71 is a unit that selects and determines a setting operation screen 72 (also referred to as a virtual switch group) in the setting operation screen 72 displayed on the display unit 70 with a pointer (see FIG. 7B). . Therefore, the display unit 70 not only displays information related to the originally intended vehicle-mounted device, but also displays a setting operation screen 72 for appropriately switching the information on the various vehicle-mounted devices described above. This is the same configuration as the multi-display device described above.

  In such a display form, as shown in FIG. 7B, while the driver performs a selection / setting operation or the like on the selection setting screen 72 displayed on the display unit 70, for example, map information or Travel control information is hidden. Then, it is impossible to always recognize the vehicle information that is originally required, such as missing the route guidance by the car navigation device, and use it at an appropriate timing.

  Further, as shown in the figure, the display unit 70 is fixed at a substantially central position of the instrument panel 73. However, if there is the display unit 70 at this position, external light is easily incident on the display unit 70, The display part 70 will shine by light reflection. Then, it becomes very dangerous because it obstructs the driver's recognition of the front, and it is even more dangerous when the selection setting screen 72 is operated.

  An object of the present invention is to solve the above-mentioned problems, and can always display information on the on-vehicle equipment that changes every moment without interruption, and prevents hindrance to the driver's view due to external light reflection, An object of the present invention is to provide a vehicle-mounted display device that contributes to safe and comfortable vehicle travel.

And a main body unit 5 on which a control unit for executing an operation instruction by the operation unit 4 is mounted.
The information display unit 3 and the operation unit 4 are arranged at independent positions.
In particular, the information display unit 3 is a liquid crystal screen or an EL panel, and displays only information related to the on-vehicle equipment.
On the other hand, the operation unit 4 is also a liquid crystal screen or an EL panel, and displays only a setting operation screen for executing a selection setting operation for displaying information related to the desired on-vehicle equipment and an operation operation for the on-vehicle equipment. . The operation unit 4 is detachably attached to the main body unit 5.

Next, the present invention will be described based on the illustrated embodiment.
FIG. 1 is a schematic explanatory view of a vehicle compartment including an in-vehicle display device 2 according to an embodiment of the present invention. In the vehicle according to the present embodiment, the in-vehicle display device 2 is arranged at a substantially central position in the vehicle width direction on the upper surface of the dashboard 1, that is, a position between the driver seat and the passenger seat.
As shown in the side view of FIG. 2, the in-vehicle display device 2 selects and displays an information display unit 3 that displays information related to a vehicle-mounted device, and information related to a desired vehicle-mounted device displayed on the information display unit 3. In addition, the operation unit 4 that operates the operation of the vehicle-mounted device and the main body unit 5 that includes a control unit that executes an operation instruction by the operation unit 4 are integrally connected. The in-vehicle display device 2 having the above-described configuration is attached to the vehicle by connecting the back surface of the main body 5 and the upper surface of the dashboard 1 by a connecting means 10 that can rotate in the horizontal direction.

  In this in-vehicle display device 2, as shown in the figure, the information display unit 3 and the operation unit 4 are arranged at independent positions such as a notebook computer, and the display roles of the information display unit 3 and the operation unit 4 are as follows. The feature is that it is clearly divided.

That is, the information display unit 3 is a liquid crystal screen or an organic or inorganic EL (Electro-Luminescence) panel characterized by high brightness, high contrast and a wide viewing angle. The upper end side is formed in an ellipse so as not to disturb the driver's forward view. Further, a hinge means 6 is provided at the lower end of the information display section 3 and is connected to the main body section 5 so that the information display section 3 can be opened and closed. The hinge means 6 freely fixes the rising position of the information display section.
On the screen of the information display unit 3, only information related to the on-vehicle equipment is displayed. Here, the vehicle-mounted device is, for example, an air conditioner (air conditioner), audio (radio, cassette tape, MD, CD, DVD, etc.), navigation device, external information acquisition device, and speed required for vehicle travel control. A sensor system that provides various information from a meter, a fuel gauge, a water temperature gauge, and the like. Further, the information related to the on-vehicle equipment is information provided when the desired on-vehicle equipment is operated, for example, map information of a navigation device, travel control information such as a speed meter, a fuel gauge, and the like. FIG. 3 shows a state where map information is displayed by the navigation device. Of course, you may display the operating information of an audio equipment or an air conditioning apparatus.

  When opening the information display unit 3 configured as described above, the angle is tilted to the front of, for example, about 65 degrees (θ1) that is not perpendicular to the driver's visual recognition direction S, and external light incident on the information display unit 3 ( It is preferable to deviate the reflection direction of G1, G2) from the driver. When tilted to the front as described above, keyton correction is appropriately performed to prevent the screen from being distorted. The keyton correction is performed by adjusting the horizontal and / or vertical scaling ratio on the display element so that the distortion on the screen and the distortion of the video area on the display element are offset. By projecting a distorted image, the image is displayed on the screen as an image display area having a normal aspect ratio. As another countermeasure against external light, the vehicle-mounted display device 2 main body can be rotated in the horizontal direction by the rotatable connecting means 10 to avoid external light reflection.

  Next, the operation unit 4 will be described. The operation unit 4 is a liquid crystal screen or an organic or inorganic EL (Electro-Luminescence) panel characterized by high brightness, high contrast and a wide viewing angle, and can be operated by touching the screen (touch panel). ). As described above, the in-vehicle display device 2 in which the operation unit 4 is a touch screen type liquid crystal or EL panel is not seen or heard.

  On the screen of the operation unit 4, only a selection setting operation for displaying information related to the desired vehicle-mounted device and a setting operation screen for smoothing the operation operation of the vehicle-mounted device are displayed. A virtual operation switch group is displayed on the setting operation screen, and selection, setting, editing, and the like of the on-vehicle equipment can be executed. As an example, FIG. 4 shows a screen for performing a destination selection / setting operation corresponding to the map information by the navigation device of FIG.

As shown in FIG. 5, the liquid crystal screen of the operation unit 4 or the screen of the EL panel is displayed as a black screen while not being operated. Therefore, even if the external light G3 is incident on the screen of the operation unit 4, the operation screen 4 can be prevented from being reflected on the screen of the information display unit 3.
As a further means for preventing the screen of the operation unit 4 from appearing on the information display unit 3, it is preferable to use a low-reflection polarized liquid crystal (for example, a low-reflection black TEF liquid crystal) for the liquid crystal screen of the operation unit 4. This low reflection polarization type liquid crystal is designed such that a plurality of antireflection films are laminated on its surface and the reflected light of each layer cancels each other. Therefore, even when the operation unit 4 is being operated, the reflection on the information display unit 3 can be prevented.

  Further, the operation unit 4 is configured to be detachably fitted in a storage space provided in the main body unit 5. When the operation unit 4 is removed from the main body unit 5 and operated, wireless communication, for example, an ISM band such as Bluetooth or wireless LAN, which is a 2.4 GHz or 5.8 GHz band, is used. Therefore, the operation can be left to passengers in the passenger seat and the back seat other than the driver, so that the driver can concentrate on driving and contribute to the realization of safer and more comfortable driving.

  Next, the main body 5 will be described. The main body 5 houses the operation unit 4 described above and also includes a battery 50. The battery 50 is, for example, a rechargeable lithium secondary battery or the like, and is configured to be charged by being connected to the ACC of the vehicle. Furthermore, the structure which affixes the solar sheet 30 (a solar panel is also included) on the back surface (front glass side) of the said information display part 3, and can charge also from sunlight without depending on a vehicle power supply is more preferable.

  Although not shown in the figure, the main body unit 5 includes a control unit (software) that executes an instruction from the operation unit 4. This control unit is connected to the various vehicle-mounted devices described above, and displays a plurality of setting information for each device that can be selected by the operation unit 4 (in this case, the setting information is various setting operation screens) on the screen of the operation unit 4. Setting operation display means to be displayed, and vehicle-mounted equipment information display means for displaying information content (information on the selected vehicle-mounted equipment) based on the setting operation of the operation section 4 on the information display section 3.

  The operation unit 4 is not limited to that of the first embodiment. Although not shown, the operation unit 4 is a cursor pad (also referred to as a pad-type pointing device) for operating a selection setting screen displayed on the screen in addition to the liquid crystal screen and the organic or inorganic EL panel screen. ) Is also preferably implemented. Therefore, even when the liquid crystal or the touch screen of the panel does not react normally, the operation can be performed with the cursor pad.

The shape of the information display unit 3 is not limited to that of the first embodiment, and as shown in FIG. 6, it is also preferable to use an information display unit 3 ′ whose cross-sectional shape is curved in a C shape. it can.
The advantage that the screen is curved in a C shape is that the height H2 of the information display unit 3 ′ can be reduced to be lower than the height H1 of the information display unit 3, and the visibility range in front of the driver is increased. In addition, the angle range with respect to external light reflection is widened, and the external light projected on the information display unit 3 ′ is greatly reflected in a direction that does not interfere with the driver's field of view. The danger can be prevented reliably.

  On the screen that is tilted to the front and curved, the lateral image on the side closer to the driver's viewpoint (eye point) on the screen is enlarged, and the lateral image on the far side is reduced. The curvature of the curved screen is combined with this, resulting in a large distortion. Therefore, the horizontal image at the screen edge close to the driver's viewpoint (eye point) is used as the enlargement area standard (same size), and the image horizontal direction at the screen edge far from the driver's viewpoint (eye point) becomes equal to the enlarged area. Perspective correction for enlarging while changing the magnification of each point is appropriately performed.

  Although the embodiments have been described with reference to the drawings, the present invention is not limited to the illustrated examples, and includes a range of design changes and application variations that are usually made by those skilled in the art without departing from the technical idea thereof. I will add that just in case. In the third embodiment, the case where the cross-sectional shape of the information display unit 3 ′ is curved in a C shape has been shown. However, for example, the right and left edges of the screen may be curved inward to widen the angle range for external light reflection. Is possible.
