Hereinafter, the in-vehicle display device according to the present embodiment will be described with reference to the drawings. The in-vehicle display device of the present embodiment is applied to a display unit incorporated on the surface as a part of the instrument panel.
(First embodiment)

FIG. 1 is a front view showing an external appearance in the vicinity of an instrument panel 20 in which a display unit 32 that is an in-vehicle display device in the first embodiment is incorporated.
A windshield 10, a front mirror 13, an instrument panel 20, various display device groups 30, a handle 50, and the like are disposed in the passenger compartment as viewed from the driver's seat side.

  A meter display 31 is arranged on the center front surface of the instrument panel 20 that is closest to the handle 50 and is easily visible from the driver among the various display device groups 30. The meter display 31 displays a speedometer 31A, an engine speed meter 31B, and the like. In addition, the instrument panel 20 is formed with a meter hood 21 that serves as a cage for the meter display 31.

A pair of liquid crystal displays 36 and 38 are arranged on both sides of the meter display 31. The liquid crystal displays 36 and 38 display various information such as driving information, danger notification information, navigation information, and entertainment information.
A high mount display 34 is disposed on the upper surface of the instrument panel 20. The high mount display 34 displays an image of a direction indicator, for example.

  Further, a head-up display 35 that projects toward the windshield 10 is disposed on the upper surface of the instrument panel 20 adjacent to the windshield 10. The head-up display 35 projects speed information and the like onto a region 35a on the windshield 10 that is easily visible to the driver. In FIG. 1, the speed “60 km” is shown.

  Further, a line illumination 39 extending in the left-right direction is disposed below the meter display 31 of the instrument panel 20. The line illumination 39 is formed by arranging a plurality of LED light sources in the left-right direction.

  On the other hand, a display unit 32 is incorporated in front of the instrument panel 20 on the passenger seat side. The display unit 32 extends along the surface of the instrument panel 20 from the front surface of the instrument panel 20 on the passenger seat (passenger seat) side to the vicinity of the front end of the windshield 10. It is a display device incorporated so as to be substantially the same surface as the body surface.

  FIG. 2 is a perspective view showing the structure of the display unit 32. The display unit 32 is a display device having a sense of depth so as to extend from the front surface of the instrument panel 20 to a position close to the front end portion of the windshield 10 (near the front end portion). The panel 70 is superposed.

  The LED circuit body 60 has a plurality of LED light sources (point light sources) 65 arranged in a stepped manner on a flexible mount base 63. Note that the mount base material is a plastic material, and may be molded in accordance with the shape of the curved surface of the instrument panel. On the other hand, the front panel 70 has a curved shape so as to overlap the LED circuit body 60. As will be described later, a plurality of pores 71 (see FIG. 3) corresponding to the LED light source are formed on the surface of the front panel 70.

FIG. 3 is a cross-sectional view showing a part of the structure of the display unit 32 in an enlarged manner. A large number of holes 66 (steps) are formed on the surface of the mount base 63 so as to open toward the passenger seat. An LED light source 65 is disposed on the bottom surface of each hole 66.
The front panel 70 is formed with a plurality of pores 71 so that the light L of the LED light source 65 emitted from the plurality of holes 66 is directed toward the passenger seat. The number of the pores 71 is about 6 to 9 for one LED light source 65. Each pore 71 has a predetermined angle with respect to the thickness direction of the surface panel 70. The inclination angle of the pore 71 is smaller as it is closer to the passenger seat, and is larger as it is closer to the windshield 10. In addition, the inclination angle of the pore 71 may be 0 degree at a location where the surface of the front panel 70 is perpendicular to the direction toward the passenger seat.

  Further, the hole 66 is also inclined with respect to the thickness direction of the mount base 63, and the inclination angle is smaller as it is closer to the passenger seat, similar to the pore 71, and is closer to the windshield 10. The larger the value, the larger the value. The inner wall portion of the hole portion 66 also functions as a member serving as a ridge that prevents the light L from the LED light source 65 from going toward the windshield 10.

  As described above, the inner wall portion of the hole 66 and the pore 71 of the front panel 70 have a light guiding function for guiding light emitted from the LED light source 65 disposed on the mount base 63 to the passenger seat side in the vehicle interior. The light guiding function may be realized by only one of the inner wall portion of the hole 66 and the pore 71 of the front panel 70.

  FIG. 4 is a diagram for explaining the traveling direction of the light L projected from the LED light sources 65 arranged on the mount base 63 through the front panel 70. As described above, the inclination angle of the pores 71 formed in the front panel 70 gradually increases from the passenger seat side to the front end portion of the windshield 10, so that all the LED circuit bodies 60 are arranged. The light L from the LED light source 65 is directed toward the face of the occupant 55 seated in the occupant seat (see dotted line frame m). Therefore, the occupant 55 can capture light from all the LED light sources 65 without changing the direction of the line of sight.

  In the display unit 32, the LED light sources 65 arranged on the mount base 63 are arranged in a row continuously from the passenger seat side to the front end of the windshield 10, so that when the lighting is turned on, the sense of depth The display with can be made. In addition, when the light is turned off, the LED circuit body 60 located inside the front panel 70 of the display unit 32 is hidden by the pores 71 of the front panel 70, and outside light is difficult to enter the front panel 70. Since it becomes darker than the surroundings, it is difficult for the passenger to notice the presence of the LED circuit body 60.

The speed sensor 56 detects the speed of the vehicle. The inter-vehicle distance sensor 57 transmits and receives infrared rays, measures the distance to the object, and detects the approach to the host vehicle. In addition, the structure by which the approach to the own vehicle is detected by analyzing the image imaged with the camera may be sufficient. Further, a plurality of inter-vehicle distance sensors 57 may be provided so as to detect the approach of the object to the own vehicle not only in the front and rear of the vehicle but also in the left-right direction.
The navigation device 58 is equipped with GPS (Global Positioning System) and map data, and has a function of guiding the host vehicle to a destination. Here, the navigation screen is displayed on the liquid crystal display 36. The speaker 59 emits sound information such as driving information, warnings, music, and the like in accordance with the audio data output from the control device 52. The operation SW 53 is used for various switch inputs by the driver, such as selection of entertainment information.

  Next, a display operation by the control device 52 using the display unit 32 will be described. 6 and 7 show display examples when a plurality of display devices are operated in cooperation. FIG. 6A shows a display example when an overspeed occurs. When the speed of the vehicle detected by the speed sensor 56 exceeds the legal speed or the like, the control device 52 lights the display unit 32 in red. In cooperation with this display operation, the control device 52 projects the vehicle speed projected by the head-up display 35 and projected on the area 35a of the windshield 10 in a blinking manner.

  In this way, by displaying the display unit 32 and the head-up display 35 in cooperation with each other, the driver can easily recognize that the speed is exceeded and have a consciousness of encouraging safe driving. become.

  Further, as the excess of the speed increases, the brightness of the light that turns on the display unit 32 may be increased, the emission color may be changed, or the blinking period of the speed image projected on the windshield 10 may be shortened. The degree of warning that the driver is overspeeding (over) can also be increased.

  FIG. 6 (B) shows a display example when warning of approach of the vehicle. When the approach to the host vehicle detected by the inter-vehicle distance sensor 57 is less than a predetermined distance and the risk of collision increases, the control device 52 indicates an arrow mark a indicating the approaching direction of the vehicle to the display unit 32. Is moved from the windshield 10 side toward the front surface of the instrument panel 20. That is, display with a sense of perspective is performed so that the arrow mark a approaches from the distance. Further, as the arrow mark a moves, the control device 52 causes the head-up display 35 to project a message of an approach distance (here, 2 m) onto the area 35a of the windshield 10 and lights up so as to flow through the line illumination 39. Let

  In this way, by displaying the three display devices in association with each other, the driver can immediately notice that it is in a dangerous situation, and can prompt the driver to take a risk-avoidance action. .

  FIG. 7A shows a display example when music is reproduced. When the driver operates the operation SW 53 using the entertainment information displayed on the liquid crystal display 36 to select, for example, music (music aaa), the control device 52 plays music from the speaker 59 and simultaneously displays the display unit. A waveform b that changes in accordance with the rhythm and tempo of the flowing music is displayed on the line 32, and the lighting portion is moved so that the line illumination 39 flows in accordance with the rhythm and tempo of the music.

  In this manner, the display unit 32 changes the display according to the music flowing from the speaker 59, so that an atmosphere in which the driver enjoys music together with the vehicle is created in the passenger compartment, and the occupant enjoys music. Can enjoy more.

  FIG. 7B shows a display example when guidance is provided by the navigation device 58. The liquid crystal display 36 displays a navigation screen in which the vehicle mark is superimposed on the map information. For example, when the control device 52 receives a signal for instructing a right turn from the navigation device 58, the control device 52 controls the lighting of the display unit 32 and displays the mark c representing the right turn formed by the lighting of the plurality of LED light sources 65. As a result, the driver performs driving according to the navigation instruction without overlooking the large mark c indicating the right turn.

  Furthermore, the display unit 32 uses a plurality of LED light sources 65 as point light sources, regardless of whether or not the liquid crystal display 36 or the line illumination 39 is linked, and emits various contents such as characters, pictures, symbols, etc. It can be displayed by a combination of. For example, the display unit 32 may display a smile mark when the vehicle is running smoothly or during the reproduction of light music. Conversely, when the vehicle is running with poor fuel consumption, a crying face or a troubled face mark may be displayed. In addition to this, the display unit 32 may display a message such as speed, weather information, a sign such as “stop”, a line according to the distance between vehicles, and a message such as when starting up.

  As described above, the display unit 32 of the first embodiment is incorporated in the housing surface of the instrument panel 20 on the passenger seat side. Further, the display unit 32 is provided so as to cover the display surface of the mount base 63 and the mount base 63 in which a plurality of LED light sources 65 are arranged along the housing surface of the instrument panel 20. And a surface panel 70 for guiding light emitted from the LED light source 65 to the passenger seat side in the passenger compartment. The inner wall portion of the hole 66 formed in the mount base 63 also guides the light emitted from the LED light source 65 to the passenger seat side in the passenger compartment. Therefore, the display unit 32 incorporated in the instrument panel 20 that forms the passenger compartment can display various information to the passenger without being reflected on the windshield 10.

  In addition, the display unit 32 incorporated in the surface of the instrument panel 20 on the passenger seat side cooperates with other display devices such as the liquid crystal display 36 and the line illumination 39 to change the display in various ways. Notify driving information, danger information, entertainment information, etc. Thereby, the display suitable for each role is attained with respect to each display device.

  Thus, since various information is displayed by the display unit incorporated in the instrument panel which forms a vehicle interior, a sense of unity between the displayed driving information and the vehicle can be felt. As a result, it is expected that information transmission efficiency to passengers including the driver will be improved. Therefore, the driver's interest level is also increased, and contribution to safe driving is expected.

  In addition, since a display unit is built into the instrument panel on the passenger side, information that is not directly related to driving, such as entertainment information, can be displayed on the display unit. Information can also be displayed separately.
