In particular, in the first embodiment, a case where two notification displays 104A and 104B and two detailed information displays 105A and 105B are provided will be described as an example.

  FIG. 2 shows an appearance when the front in the traveling direction is viewed from the center of the passenger compartment. A center cluster 12 is disposed in the center of the dashboard 11, and a steering wheel 13 and an instrument panel 14 are disposed in front of a driver who sits on the right side of the center cluster 12. A right front pillar 15R and a right door mirror 16R are disposed at the right end of the dashboard 11, and a left front pillar 15L and a left door mirror 16L are disposed at the left end of the dashboard 11.

  The detailed information display 105 </ b> A is an in-meter display that is arranged in the instrument panel 14 and can display vehicle information. The detailed information display 105 </ b> B is a navigation system that displays navigation information including characters and images arranged in the center cluster 12.

  The detailed information display 105A and the detailed information display 105B are arranged side by side in a substantially horizontal direction, and the notification display 104A is arranged on the dashboard 11 between the detailed information display 105A and the detailed information display 105B. Has been. In other words, the detailed information display 105A and the detailed information display 105B are arranged so as to sandwich the notification display 104A in the horizontal direction. However, the notification display 104A does not have to be arranged in a region formed by the tangent line between the outer periphery of the detailed information display 105A and the outer periphery of the detailed information display 105B, and the center of the detailed information display 105A is not necessary. What is necessary is just to arrange | position between the vertical line which passes and the vertical line which passes the center of the detailed information display 105B.

  The notification display 104B is disposed on the dashboard 11 on the right side of the vertical line passing through the center of the detailed information display 105A. The notification displays 104A and 104B are installed so as to sandwich the detailed information display 105A. However, the detailed information display 105A does not have to be arranged in a region formed by the tangent line between the outer periphery of the notification display 104A and the outer periphery of the notification display 104B, and the center of the notification display 104A is not necessary. What is necessary is just to arrange | position between the vertical line which passes and the vertical line which passes along the center of the display 104A for alerting | reporting.

  An example of a specific configuration of the notification indicators 104A and 104B in FIG. 2 will be described with reference to FIGS. 3 (a), 3 (b), and 3 (c). The notification displays 104A and 104B have the same configuration. Inside the housing 301, the substrate 302 is fixed so that one main surface of the substrate 302 faces the opening surface of the housing 301. Three light emitting diodes (LEDs) 303 </ b> A, 303 </ b> B, and 303 </ b> C are fixed on one main surface of the substrate 302 with the light emitting surfaces of the LEDs 303 </ b> A to 303 </ b> C facing the opening surface of the housing 301. The opening surface of the housing 301 is closed by a diffusion plate 304. Light emitted from the LEDs 303 </ b> A to 303 </ b> C is diffused, for example, in a circular shape by the diffusion plate 304, passes through the diffusion plate 304, and is emitted toward the vehicle interior.

  The notification displays 104A and 104B each include a light emission control mechanism that controls light emission by controlling luminance or hue based on a predetermined time frequency set in advance. The light emission control mechanism will be described below. The light from each of the LEDs 303A to 303C is diffused by the diffusion plate 304, and emits light by causing a luminance change as shown in FIG. That is, when the driver visually recognizes the diffusing plate 304, as shown in FIG. 4A, the luminance at the center is the highest, and the luminance gradually decreases toward the circumferential direction on a concentric circle (gradual luminance). (It will be a change).

  FIG. 4B is a diagram showing the relationship between the luminance and the light emission width in the light emission state shown in FIG. The vertical axis represents the luminance, and the horizontal axis represents the light emission width (or the diameter when the light emission is circular). The light emission width shown in FIG. 4B is set to about 5 mm to 30 mm, and is set as appropriate according to the application and design within this range.

  In FIG. 4A, the luminance changes gently in all directions in the circumferential direction around the light spot, but the luminance changes gently in any one direction (left and right direction, up and down direction, etc.). It may be a display form. For example, as shown to Fig.5 (a), a slit is provided in the diffusion plate 304, and the light emitted from each LED303A-303C is light-emitted toward a vehicle interior via this slit. Thereby, the display form by light emission becomes a rectangle whose left and right are longitudinal directions. As a result, when the driver visually recognizes the notification displays 104A and 104B, a display form in which the luminance gradually changes in the horizontal direction is possible.

  FIG. 5B is a diagram showing the relationship between the luminance (vertical axis) and the light emission width (horizontal axis) in the light emission state shown in FIG. In the case of such a display mode, the light emission width only needs to be about 5 mm to 30 mm in the direction in which the luminance changes gradually. On the other hand, the emission width in a direction other than the horizontal direction (for example, the vertical direction) may be smaller than that in the horizontal direction.

  The size of the light emission width is set based on the spatial frequency. As shown in FIGS. 6A and 6B, the spatial frequency is calculated as W / θ based on the light emission width (W) and the angle (θ) of the LEDs 303A to 303C. The angle (θ) is the horizontal light emission width of each LED 303A to 303C based on the eye point (eye) 602 of the driver 601 when the driver 601 seated visually recognizes the notification displays 104A and 104B. It is an angle in the horizontal direction with respect to (W).

  The spatial frequency expressed in this way, if the light emission width is about 5 mm to 30 mm, the driver's seating position and the disposition position of the notification indicators 104A and 104B are taken into consideration, and the driver can see in the peripheral vision. It can be set as the display form which can be visually recognized. Here, the peripheral vision is a visual field in which the peripheral part of the visual field is vaguely seen using the peripheral part of the retina, and this peripheral vision is suitable for capturing movement and position.

  The main controller 101 includes various onboard vehicle sensors such as various sensors and cameras, an ECU (Engine Control Unit), an inter-vehicle maintenance support system, an intelligent cruise control system, a navigation system, and the like. Get information. The “various information” includes, for example, a decrease in the remaining amount of fuel, approach of other vehicles, and route guidance information. These various types of information are given to the main controller 101 at the time when the remaining amount of fuel is reduced, the approach of other vehicles, and the presentation start timing of route guidance information, that is, in step S501 of FIG.

  The main controller 101 has a function of controlling the light emission of the LEDs 303A to 303C in the notification displays 104A and 104B. The main controller 101 reads the acquired various types of information, and controls the luminance of each of the LEDs 303A to 303C via the notification display control unit 102 based on the read various types of information and the control logic (program) stored in advance. .

  The change in luminance of each LED 303A to 303C is realized by controlling the current supplied to each LED 303A to 303C. For example, when the LEDs 303A to 303C are driven and controlled using a pulse width modulation (PWM) method, which is known as a known technique, the luminance can be changed by changing the duty ratio. Such a method can be realized by using, for example, an existing LED driver unit configured to control the LED current by the PWM method. Note that the light emission control mechanism described above may control the hue instead of the luminance.

  The notification display control unit 102 in FIG. 1 can independently change the luminance of the LEDs 303A to 303C. Fig.7 (a)-FIG.7 (c) each show an example of the time change of the brightness | luminance of LED303A-303C, respectively. For example, at different times (MAXA, MAXB, MAXC), the amount of current that flows through the LEDs 303A to 303C is changed so that the luminance of the LEDs 303A to 303C has a maximum value. Then, the luminance increases in the order of LED 303A, LED 303B, and LED 303C, and the driver looks like the light flows in the right direction. The reverse direction, that is, the left direction can be indicated by changing the order of the LED 303A and the LED 303C. By performing such brightness control, the notification display 104A can call attention to the detailed information display 105A or 105B. Here, a case where a one-dimensional direction is indicated using three LEDs is shown, but if the number of LEDs is increased and arranged in a predetermined layout, the notification displays 104A and 104B are arranged in a plurality of two-dimensional directions. Can be shown.

  Next, an example of the operation of the vehicle display device according to the first embodiment will be described with reference to FIG.

  In step S501, the main controller 101 acquires vehicle information, various sensors installed in the vehicle, and information from outside the vehicle by means such as CAN communication or wireless communication. In this example, a case is considered where information notifying vehicle abnormality is acquired.

  In step S502, the main controller 101 performs processing based on the acquired information, and determines the contents to be displayed on the detailed information displays 105A and 105B. If there is no content to be displayed, the processing operation shown in FIG. 8 ends. In this example, it is determined to display a message notifying the type of vehicle abnormality.

  In step S503, the main controller 101 selects the detailed information displays 105A and 105B that display the determined display contents, that is, the detailed information displays 105A and 105B on which the information is updated. Specifically, the main controller 101 refers to a table (data) to be described later, and selects one of the detailed information displays 105A and 105B according to the determined display content. The selection of the detailed information display is a table indicating the correspondence between the display contents and the detailed information display that is stored in advance in the main controller 101 or stored in advance in an external device accessible by the main controller 101. Based on (data). In this example, the detailed information display 105A arranged in the instrument panel 14 is selected as a detailed information display for updating information.

  In step S504, the main controller 101 determines which notification displays 104A and 104B are used to call attention to the detailed information displays 105A and 105B where the information is updated, and the determined notifications. The directions indicated by the display devices 104A and 104B are determined. The main controller 101 stores in advance the layout data of the notification displays 104A and 104B and the detailed information displays 105A and 105B in the passenger compartment, and the notification displays 104A and 104B to be used and the notification based on the layout data. The direction in which the display 104A, 104B for display is displayed can be determined. In this example, the detailed information display 105A is selected as a detailed information display for updating information. Therefore, in the main controller 101, the notification displays used are the notification displays 104A and 104B, the direction indicated by the notification display 104A is the right direction, and the direction indicated by the notification display 104B is the left direction. Determine that there is.

  In S505, the main controller 101 notifies the notification display 104A determined in step S504 via the notification display control unit 102 so that the notification displays 104A and 104B call attention to the detailed information display 105A. 104B is controlled. In this example, the notification display 104A displays the right direction, and the notification display 104B displays the left direction. Thereby, the main controller 101 can present to the driver that the information has been updated and that the detailed information display with the updated information is the detailed information display 105A. The notification displays 104A and 104B are installed so as to sandwich the detailed information display 105A, and the two notification displays 104A and 104B pay attention to the detailed information display 105A in which information has been updated. Raise in cooperation. As a result, the driver can easily specify the detailed information display with the updated information.

  In step S506, the main controller 101 controls the detailed information display device 105A via the detailed information display control unit 103 so that the detailed information display devices 105A and 105B determined in S503 display the display content determined in S502. , 105B. In this example, a message notifying the type of vehicle abnormality is displayed on the detailed information display 105A arranged in the instrument panel 14.

  With the above operation, the driver can obtain detailed information as a detailed information display device in which information is updated from the right display displayed on the notification display 104A and the left display displayed on the notification display 104B. The message indicating the type of vehicle abnormality displayed on the detailed information display device 105A can be instantly acquired by easily specifying the display device 105A.

  Next, another example of the operation of the vehicle display device according to the first embodiment will be described. In this example, consider a case where a short message is received via a mobile phone connected to the vehicle in step S501. In step S502, the main controller 101 determines, as display contents, a message notifying receipt of a short message and a sender of the short message.

  In step S503, the main controller 101 selects the detailed information display 105B arranged in the center cluster 12 as a detailed information display on which information is updated. In step S504, the main controller 101 determines that the notification display to be used is the notification display 104A, and the direction indicated by the notification display 104A is the left direction.

  In step S505, the main controller 101 controls the notification display 104A via the notification display control unit 102 so that the notification display 104A calls attention to the detailed information display 105B. Specifically, the notification display 104A is controlled to display the left direction. Nothing is displayed on the notification display 104B that is not used. As a result, the main controller 101 can present to the driver that the information has been updated and that the detailed information display with the updated information is the detailed information display 105B.

  Next, in step S506, the main controller 101 causes the detailed information display device 105B determined in S503 to display the display content determined in S502 via the detailed information display control unit 103. 105B is controlled. In this example, a message notifying the reception of the short message and a message notifying the sender of the short message are displayed on the detailed information display 105B arranged in the center cluster 12.

  Through the above operation, the driver easily specifies the detailed information display device 105B as the detailed information display device with the updated information from the left display displayed on the notification display 104A, and the detailed information display device 105B. It is possible to instantly acquire a message notifying the reception of the short message displayed on the screen and a message notifying the sender of the short message.

  As described above, according to the first embodiment of the present invention, the main controller 101 displays the notification display 104A so as to call attention to the detailed information display 105B that has been updated. To control. As a result, the notification display 104A makes the driver aware of the update of the information in the detailed information display 105B, and at the same time, updates to which detailed information display among the plurality of detailed information displays 105A and 105B. You can tell if there was. Therefore, the driver can easily determine which detailed information display 105A, 105B has been updated, and can quickly acquire the updated information.

  Further, as shown in FIGS. 3A to 3C and FIG. 7, the notification indicators 104A and 104B have a function of indicating a direction. For this reason, it is possible to call attention to the detailed information displays 105A and 105B with a smaller number of notification displays 104A and 104B, the installation area of the notification displays 104A and 104B is reduced, and the notification display is displayed. The manufacturing cost of the devices 104A and 104B is reduced.

  Also, two notification displays 104A and 104B are installed so as to sandwich the detailed information display 105A. That is, the detailed information display 105A is disposed at a position sandwiched between the two notification displays 104A and 104B, and the detailed information display 105B is disposed outside the two notification displays 104A and 104B. Therefore, the driver can narrow down the position of the detailed information display 105A where the information has been updated to a narrower range, so that the updated information can be acquired more easily.

  In addition, the two notification displays 104A and 104B call attention to the detailed information display 105A in which the information has been updated in cooperation. That is, when the two notification displays 104A and 104B display the directions in cooperation, the detailed information display 105A at the sandwiched position is indicated, or the outer detailed information display 105B is indicated. As a result, the driver can easily specify the detailed information displays 105A and 105B in which the information has been updated, and as a result, the information can be easily acquired. In particular, the outer detailed information display 105B can be easily identified.

  In step S506, the main controller 101 causes the detailed information display 105B arranged in the center cluster 12 to display a message notifying the reception of the short message and a message notifying the sender of the short message.

  With the above operation, the driver can use the detailed information display device with updated information from the left display displayed on the notification display 104A and the right display displayed on the notification display 104C. The display device 105B can be easily identified, and a message notifying the reception of the short message displayed on the detailed information display device 105B and a message notifying the sender of the short message can be acquired instantaneously.

  Next, another example of the operation of the vehicle display device according to the second embodiment will be described. In this example, let us consider a case where, in step S501, a sensor provided in the vehicle detects another vehicle on the left rear side of the host vehicle. In this case, in order to direct the driver's attention to another vehicle located on the left rear side of the host vehicle, in step S502, the main controller 101 displays the left side of the vehicle visually recognized by the driver via the left door mirror 16L as the display content. Decide on the rear image.

  In step S503, the main controller 101 selects the detailed information display 105C (left door mirror 16L) as a detailed information display on which information is updated. In step S504, the main controller 101 determines that the notification display to be used is the notification display 104C, and the direction indicated by the notification display 104C is the left direction.

  In step S505, the main controller 101 controls the notification display 104C via the notification display control unit 102 so that the notification display 104C calls attention to the detailed information display 105C (left door mirror 16L). To do. Specifically, control is performed so that the notification display 104C displays the left direction. Nothing is displayed on the notification displays 104A and 104B that are not used. As a result, the main controller 101 can present to the driver that the information has been updated and that the detailed information display with the updated information is the detailed information display 105C (the left door mirror 16L).

  In the case where the left door mirror 16L has a function of adding video information superimposed on the left rear image of the vehicle, in step S506, the main controller 101 displays the left side of the host vehicle on the detailed information display 105C (left door mirror 16L). Video information is displayed to inform the driver that there is another vehicle behind. Note that if the left door mirror 16L does not have the function of adding video information superimposed on the left rear image of the vehicle, step S506 is not performed.

  With the above operation, the driver easily specifies the detailed information display device 105C (left door mirror 16L) as the detailed information display device with the updated information from the left display displayed on the notification display 104C. The left rear image of the vehicle displayed on the detailed information display device 105C (the left door mirror 16L) and the video information superimposed on the left rear image of the vehicle can be acquired instantaneously.

  Similarly to this example, when another vehicle is detected on the right rear side of the host vehicle, the driver starts the detailed information display 105D (right door mirror 16R) from the right display displayed on the notification display 104B. And the video information added to the right rear image and the right rear image of the vehicle displayed on the detailed information display device 105D (right door mirror 16R) can be acquired.
