  The HUD device 200 is configured by the above units. FIG. 3 shows a display example of the HUD device 200. In FIG. 3, the vehicle speed SP, which is vehicle information, is digitally displayed as a virtual image V of the display image.

  Returning to FIG. 1, in the in-vehicle system 1000, when the mobile phone 100 is brought into the vehicle 300 and the mobile phone 100 and the HUD device 200 are connected, the respective control units 101 and 201 are connected to each other via the wireless communication interface 102. , 204 are mutually recognized. Note that when the mobile phone 100 is brought into the vehicle 300, the mobile phone 100 is placed in an arbitrary place in the vehicle interior (for example, a cradle installed on a dashboard).

Next, a method for controlling the mobile phone 100 when the navigation function is executed will be described with reference to FIG. In addition, the program concerning the following control methods shall be contained in a navigation function application.
When the navigation function application is activated, first, in step S1, the control unit 101 creates navigation information related to the route to the destination as image data composed of characters, figures, pictures, and the like. Here, the “navigation information” is information useful for traveling to a destination that is created for the purpose of correctly and comfortably guiding the vehicle 300 to the destination, such as current position information, destination and route. It is created as appropriate based on this. In this embodiment, the navigation information includes route guidance information including direction indications and lanes at intersections, highway interchanges and exit information, distance information and time information to the destination, traffic information communication system, etc. Congestion information and regulation information received from.
Next, in step S <b> 2, the control unit 101 determines whether communication with the HUD device 200 is possible. Specifically, the control unit 101 determines whether or not it is recognized that it is connected to the HUD device 200 via the wireless communication interfaces 102 and 204. When it is determined that communication with the HUD device 200 is possible (step S2; Yes), the control unit 101 proceeds to step S3, and when it is determined that communication with the HUD device 200 is not possible (step S2). No), the process proceeds to step S7.
In step S3, the control unit 101 determines whether or not a condition for transmitting navigation information to the HUD device 200 is satisfied. Conditions for transmitting navigation information to the HUD device 200 are set as appropriate for each item of navigation information. For example, in the present embodiment, the condition for transmitting the route guidance information to the HUD device 200 is a case where a predetermined travel distance is reached, and the condition for transmitting the distance information and time information to the destination to the HUD device 200 is a predetermined time. The condition for transmitting the traffic jam information and the regulation information to the HUD device 200 is when the information is on the route to the destination. When it is determined that the condition for transmitting the navigation information to the HUD device 200 is satisfied (step S3; YES), the control unit 101 proceeds to step S4 and does not satisfy the condition for transmitting the navigation information to the HUD device 200. Is determined (step S3; NO), the process proceeds to step S5.
In step S <b> 4, the control unit 101 transmits navigation information (image data) determined to satisfy the condition to be transmitted to the HUD device 200 in step S <b> 3 to the HUD device 200. The display of the HUD device 200 when the navigation information is transmitted will be described in detail later. After executing Step S4, the control unit 101 proceeds to Step S5.
Next, in step S5, the control unit 101 determines whether route guidance to the destination is being executed in the activated navigation function application. Specifically, the control unit 101 determines that the route guidance is not being executed when the destination is not set or when the route guidance is interrupted by the operation of the display operation unit 104 or the execution of another application or function. In other cases, it is determined that route guidance is being executed. When it is determined that the route guidance to the destination is being executed (step S5; YES), the control unit 101 proceeds to step S6 and determines that the route guidance to the destination is not being executed. In the case (step S5; NO), the process proceeds to step S7.
In step S <b> 6, the control unit 101 transmits notification information notifying that the route guidance to the destination is being executed in the activated navigation function application to the HUD device 200. The display on the HUD device 200 when the notification information is received will be described in detail later. After executing step S6, the control unit 101 proceeds to step S7.
Next, the control part 101 updates the display of the display operation part 104 about the navigation function application currently started in step S7. In addition to the navigation information, the display operation unit 104 displays map information including a current position and a route to the destination.
Thereafter, the control unit 101 repeatedly executes the processes from Steps S1 to S7 until the navigation function application ends. In addition, when the navigation function application ends, the control unit 101 disconnects the connection with the HUD device 200.

Next, the display of the HUD device 200 will be described with reference to FIG.
When the power is turned on, the control unit 201 acquires vehicle information from the vehicle-side ECU 301 via the CAN diagnostic interface 302 via the CAN communication interface 203 and displays the vehicle information on the display unit 206 (FIG. 5A )reference). In FIG. 5A, the vehicle speed SP is digitally displayed as vehicle information. FIG. 5 shows a virtual image V of the display image on the display unit 206.
In addition, when the navigation unit receives the navigation information from the mobile phone 100 to the wireless communication interface 204, the control unit 201 displays the received navigation information in a predetermined display area of the display unit 206 (see FIG. 5B). In FIG. 5 (b), as the navigation information, route guidance information NV1 indicating the traveling direction at the intersection is displayed with an arrow-shaped icon, and distance information NV2 to the destination is digitally displayed. The navigation information is displayed in a display area different from the display area for displaying the vehicle information so as not to hinder the display of the vehicle information. In addition, when the received navigation information includes a plurality of items, only items having a predetermined high priority may be displayed.

  Further, when the control unit 201 receives the notification information from the mobile phone 100 to the wireless communication interface 204, the control unit 201 determines that the route guidance to the destination is being executed in the navigation function application, and is executing the route guidance. As a notification operation for notifying the viewer 400 of this, a predetermined notification image WR1 is displayed in a predetermined display area of the display unit 206 (see FIGS. 5B and 5C). In the present embodiment, the notification image WR1 is composed of characters “NAVI”. The notification image WR1 is displayed in a display area different from the display area for displaying the vehicle information so as not to hinder the display of the vehicle information. Since the control unit 201 displays the notification image WR1 based on the reception of the notification information from the mobile phone 100, navigation is performed even when the navigation information is not received from the mobile phone 100 as shown in FIG. If the route guidance to the destination is being executed in the functional application, the notification image WR1 is continuously displayed. Therefore, the viewer 400 can confirm that the route guidance is being executed only by displaying on the HUD device 200 without confirming the display operation unit 104 of the mobile phone 100. Note that when the notification information is not received from the mobile phone 100 for a predetermined time, the control unit 201 hides the notification image WR1. Further, the control unit 201 hides the notification image WR1 when the connection with the mobile phone 100 is disconnected. Further, when it is determined in step S5 that route guidance is not being executed (step S5; NO), the mobile phone 100 transmits other notification information notifying that route guidance is not being executed to the HUD device 200. Also good. In this case, when the other notification information is received from the mobile phone 100, the control unit 201 of the HUD device 200 hides the notification image WR1.

As described above, the HUD device 200 according to the present embodiment displays vehicle information and is connected to the mobile phone 100 having a navigation function for performing route guidance to a destination so as to be communicable. Because

As the notification operation, the light emitting unit D1 is turned on or blinked. Thereby, the viewer 400 can confirm that the route guidance is being executed without confirming the mobile phone 100 by the illumination light L2 from the light emitting unit D1 provided in the HUD device 200.
Therefore, also in the HUD device 200 and the in-vehicle system 1000 according to the second embodiment, the navigation function of the mobile phone 100 can be normally performed only by the HUD device 200 without checking the mobile phone 100 as in the first embodiment. It can be determined that the device is operating, and convenience when displaying simple navigation information from the mobile phone 100 on the HUD device 200 can be improved.

  Next, a third embodiment of the present invention will be described with reference to FIG. The third embodiment is different from the above-described embodiment in that the HUD device 200 includes a light emitting unit D2 as a notification unit and a combiner 240 that emits display light L1 from the display unit 206 toward the viewer 400. The light-emitting part D2 is in the point which emits the illumination light L3 to the combiner 400 as the notification operation to make the end of the combiner 400 shine. In addition, the same code | symbol is attached | subjected to the same part as the above-mentioned embodiment, or an equivalent part, and the detail is abbreviate | omitted.

  On the upper surface of the circuit board 220 in the case body 210, a light emitting unit D2 made of LEDs is mounted. In addition, a slit portion 211 d that exposes a lower end portion including an incident portion 243 (described later) of the combiner 240 is formed in the attached portion 211 b of the upper case 211.

  The combiner 240 faces the light emitting part D2 on the lower end side thereof, receives the illumination light L3 emitted from the light emitting part D2, and enters the illumination light L3 into the combiner 240 (inside the transparent resin part constituting the combiner 240). An incident portion 243 is formed. Furthermore, the combiner 240 is directed toward the rear side, that is, the viewer 400, with the illumination light L3 guided from the incident portion 243 to the inside of the combiner 240 at the peripheral edge except the lower end side, that is, the upper end side and the left and right end side ends. An emitting portion 244 that reflects and exits to the outside (toward the left side in FIG. 8) is formed. The incident portion 243 is formed in a concave curved surface so as to diffuse the illumination light L3 to the entire interior of the combiner 240. The emitting portion 244 forms an inclined surface that is inclined at the upper end and the left and right ends of the front surface of the combiner 240 such that the upper end is located on the rear side and the lower end is located on the front side. The slanted surface is subjected to texture processing or mirror surface processing to increase the reflectance of light, or a diffusion member that diffuses light is disposed.

Upon receiving the notification information from the mobile phone 100, the control unit 201 determines that the route guidance to the destination is being executed in the navigation function application, and notifies the viewer 400 that the route guidance is being executed. As the notification operation, the light emitting unit D2 is turned on or blinked. Illumination light L3 of an arbitrary emission color emitted from the light emitting unit D2 is guided from the incident unit 243 to the inside of the combiner 240, diffuses inside the combiner 240, is reflected by the emitting unit 244, and is reflected from the peripheral portion of the concave surface 242 The light is emitted to the rear side, that is, toward the viewer 400. Accordingly, the peripheral portion of the concave surface 242 of the combiner is emitted by the illumination light L3. Thereby, it is possible to notify the viewer 400 that the route guidance is being executed without confirming the mobile phone 100 by using the peripheral portion where the virtual image V of the display image of the combiner 50 is not displayed.
Therefore, also in the HUD device 200 and the in-vehicle system 1000 according to the third embodiment, the navigation function of the mobile phone 100 can be normally performed only by the HUD device 200 without checking the mobile phone 100, as in the first embodiment.
