  Hereinafter, a plurality of modes for carrying out the invention will be described with reference to the drawings. In each embodiment, portions corresponding to the matters described in the preceding embodiment may be denoted by the same reference numerals and redundant description may be omitted. In each embodiment, when only a part of the configuration is described, the other configurations described above can be applied to other portions of the configuration.

(First embodiment)
As shown in FIG. 1, the head-up display device 2 (hereinafter referred to as “HUD2”) is provided in the host vehicle 80. The HUD 2 is housed in the instrument panel.

  The HUD 2 includes a projector 20, a reflecting mirror 21, and a concave mirror 22. The projector 20 irradiates the reflecting mirror 21 with the image as light. The reflecting mirror 21 reflects the light emitted from the projector 20 toward the concave mirror 22. The concave mirror 22 reflects the light reflected from the reflecting mirror 21 toward the windshield 70. The windshield 70 reflects the light reflected from the concave mirror 22 toward the occupant 90. Then, the occupant 90 visually recognizes the light reflected from the windshield 70 as a virtual image. That is, the HUD 2 displays the image as a virtual image 23 so that the occupant 90 can visually recognize the image.

  As shown in FIG. 2, the main ECU 1 that is the vehicle display control device of the present embodiment is connected to a gear position sensor 30, a brake sensor 31, a control switch 32, and a HUD 2. The main ECU 1 controls an image projected by the HUD 2 based on information acquired from the gear position sensor 30, the brake sensor 31, and the control switch 32. Details of processing performed by the main ECU 1 will be described later.

  The main ECU 1 is connected to the mobile terminal 40 by wireless communication. Therefore, the main ECU 1 can transmit an operation signal to the mobile terminal 40. Further, the main ECU 1 can receive various information from the mobile terminal 40. Details will be described later.

  The gear position sensor 30 detects the position of the shift gear. Specifically, the gear position sensor 30 detects whether the shift gear is parked or neutral.

  The brake sensor 31 detects whether the side brake is on or off.

  The control switch 32 is provided on the steering wheel. The control switch 32 includes an upper button, a lower button, an enter button, and the like. When the control switch is operated, an operation signal is transmitted to the main ECU 1. The main ECU 1 can operate various devices connected to the main ECU 1 such as the portable terminal 40 based on the operation signal. That is, the passenger 90 can operate various devices connected to the main ECU 1 such as the portable terminal 40 by operating the control switch 32.

  The main ECU 1 includes a control unit 10 and a memory 11. The memory 11 can store various information.

  The control unit 10 includes a microcomputer that includes a processor that performs various arithmetic processes, a RAM that functions as a work area for the arithmetic processes, and a flash memory that stores programs used for the arithmetic processes. Therefore, the control unit 10 performs arithmetic processing based on the stored program. The control unit 10 in this embodiment plays a role of the stop information acquisition unit 100 and the image output unit 101.

  The stop information acquisition unit 100 acquires stop information that is information regarding that the host vehicle 80 has stopped. Specifically, the stop information acquisition unit 100 acquires the gear position of the shift gear of the host vehicle 80 from the gear position sensor 30. When acquiring that the gear position is parking or neutral, the stop information acquisition unit 100 determines that the host vehicle 80 is stopped. Moreover, when the stop information acquisition part 100 acquires the information that the side brake is ON from the brake sensor 31, it will determine with the own vehicle 80 having stopped.

  The image output unit 101 receives predetermined data from the mobile terminal 40. Specifically, the predetermined data is e-mail data, contact data, or the like. In addition, there are stock price data and schedule data.

  And the image output part 101 transmits the image signal regarding the predetermined data received from the portable terminal 40 to HUD2. Specifically, when the image output unit 101 receives mail data, the image output unit 101 transmits an image signal such as a mail sender and a mail title to the HUD 2.

  Next, a state in which the main ECU 1 outputs an image signal related to data received from the mobile terminal 40 to the HUD 2 will be described with reference to FIGS. 3 and 4.

  FIG. 3 shows a virtual image 23 when the HUD 2 projects an image onto the windshield 70 when the stop information acquisition unit 100 acquires stop information. Currently, the mobile terminal 40 displays mail data as an image. The mail data includes data related to mail received from a store, mail received from a colleague, and mail received from a mail order company.

  The mail received from the colleague is mail that has already been opened by the occupant 90, as indicated by the mail icon. On the other hand, the mail received from the store and the mail received from the mail order company are unopened mail by the occupant 90, as indicated by the mail icon. That is, the mail received from the store and the mail received from the mail order company are data including new information.

  At this time, the image output unit 101 outputs a first mail image, which is an image based on the mail data received from the mobile terminal 40, to the HUD 2. The image output unit 101 outputs a marker image. And HUD2 projects the image output by the image output part 101. FIG. Therefore, the occupant 90 visually recognizes the first mail virtual image 231 that is a virtual image of the first mail image. Moreover, the passenger | crew 90 visually recognizes the marker virtual image 239 which is a virtual image of a marker image.

  The first email virtual image 231 is a virtual image based on the email data of the mobile terminal 40. That is, the first mail virtual image 231 is based on data about mail received from a store, mail received from a colleague, and mail received from a mail order company.

  The marker virtual image 239 can be moved by operating the upper switch and the lower switch of the control switch 32. When the determination button of the control switch 32 is operated, the mail currently surrounded by the marker virtual image 239 is opened, and a virtual image related to the data of the mail text appears. Therefore, the occupant 90 can operate the portable terminal 40 by operating the control switch 32 while visually recognizing the virtual image of the image projected by the HUD 2.

  FIG. 4 is another example showing the state of the virtual image 23 when the host vehicle 80 is stopped. When there is no unopened mail among the mail data received by the mobile terminal 40, the image output unit 101 prohibits outputting an image signal based on the mail data of the mobile terminal 40 to the HUD 2. That is, the image output unit 101 prohibits output of an image signal when new information is not included in the mail data received from the mobile terminal 40. Therefore, the image displayed by the mobile terminal 40 and the image projected by the HUD 2 are different. Therefore, when viewed from the occupant 90, the image displayed by the mobile terminal 40 and the virtual image 23 are different. At this time, the virtual image 23 includes data on the speed of the host vehicle 80 and the weather today.

  Next, a flow of a series of processes performed by the main ECU 1 will be described using the flowchart of FIG. This process is periodically performed by the main ECU 1 after the main ECU 1 is activated.

  In step S101 of FIG. 5, the stop information acquisition unit 100 determines whether stop information has been acquired. When stop information is acquired, it progresses to step S102, and when that is not right, a process is complete | finished.

  In step S <b> 102, the image output unit 101 receives predetermined data from the mobile terminal 40. Thereafter, the process proceeds to step S103.

  In step S <b> 103, the image output unit 101 detects whether or not new information is included in the predetermined data received from the mobile terminal 40. If new information is included in the predetermined data, the process proceeds to step S104, and if not, the process ends.

  In step S104, the image output unit 101 outputs an image signal based on the predetermined data received by the HUD 2. Thereafter, the process ends.

  Hereinafter, effects of the main ECU 1 in the present embodiment will be described.

  It is main ECU1 which is connected with the portable terminal 40 and controls the image which HUD2 displays. The main ECU 1 includes a stop information acquisition unit 100 and an image output unit 101. The stop information acquisition unit 100 acquires stop information that is information related to the stop of the host vehicle 80. The image output unit 101 outputs an image signal to the HUD 2. When the stop information acquisition unit 100 acquires stop information, the image output unit 101 outputs an image signal based on predetermined data received from the portable terminal 40 to the HUD 2.

  In this way, when the host vehicle 80 is stopped, the image output unit 101 automatically outputs an image signal such as a mail screen of the portable terminal 40 to the HUD 2. Therefore, the occupant 90 can view the predetermined screen immediately without performing troublesome operations after the host vehicle 80 is stopped. Further, since the predetermined screen is displayed when the host vehicle 80 is stopped, the occupant 90 can concentrate on visually recognizing the predetermined screen.

  The stop information is based on the fact that the shift gear of the host vehicle 80 is parked or neutral, or the side brake is on.

  For example, if the stop information is such that the foot brake is on, the occupant 90 must continue to perform a predetermined operation such as stepping on the foot brake in order to maintain the state where the host vehicle 80 is stopped. Then, there is a possibility that the occupant 90 cannot concentrate on viewing a predetermined screen. On the other hand, with the above configuration, the image output unit 101 outputs an image signal to the HUD 2 after ensuring that the host vehicle 80 is stopped, such as when the shift gear is input to parking. Therefore, once the stop state of the host vehicle 80 is secured, the host vehicle 80 maintains the stopped state even if the occupant 90 does not perform a predetermined operation to stop the host vehicle 80. Accordingly, the occupant 90 can concentrate by visually recognizing a predetermined screen.

  The image output unit 101 prohibits the output of the image signal to the HUD 2 when new information is not included in the predetermined data received from the mobile terminal 40.

  In this way, when the mobile terminal 40 uses the communication function to receive data including new information such as new mail, when the new data is included in the predetermined data, the image output unit 101 uses the HUD2 The image signal is output to. Therefore, the occupant 90 only needs to visually recognize a predetermined screen when the mobile terminal 40 receives new data, and the convenience is improved.

(Second Embodiment)
In 2nd Embodiment, after the own vehicle 80 is stopped, when the own vehicle 80 advances, the process which main ECU1 performs is demonstrated. In addition, a process performed by the main ECU 1 when the host vehicle 80 is stopped again after the host vehicle 80 has traveled will be described.

  First, when the host vehicle 80 is stopped, the image output unit 101 outputs an image signal based on mail data received from the portable terminal 40 to the HUD 2. That is, the virtual image 23 visually recognized by the occupant 90 includes a first email virtual image 231 as shown in FIG.

  FIG. 6 shows an image after the control switch 32 is operated when the HUD 2 projects an image as the virtual image 23 including the first mail virtual image 231 shown in FIG.

  At this time, the portable terminal 40 displays the mail data regarding the mail received from the friend, the mail received from the family, and the mail received from the boss as an image. Further, the image output unit 101 receives from the portable terminal 40 mail data related to mail received from a friend, mail received from a family member, and mail received from a supervisor. Then, the image output unit 101 outputs a second mail image that is an image based on the mail data to the HUD 2. Then, the HUD 2 projects the second mail image. Then, the occupant 90 visually recognizes the second mail virtual image 232 that is a virtual image of the second mail image. The second email virtual image 232 is based on the email data of the mobile terminal 40.

  Next, a process performed by the main ECU 1 when the host vehicle 80 is advanced from a state where the host vehicle 80 is stopped will be described.

  First, the stop information acquisition unit 100 acquires progress information that is information indicating that the host vehicle 80 has traveled from a state in which the host vehicle 80 is stopped. Specifically, the stop information acquisition unit 100 acquires the gear position of the shift gear of the host vehicle 80 from the gear position sensor 30. When acquiring that the gear position is a drive, the stop information acquisition unit 100 determines that the host vehicle 80 is traveling. Moreover, if the stop information acquisition part 100 acquires the information that the side brake is OFF from the brake sensor 31, it will determine with the own vehicle 80 progressing.

  When the stop information acquisition unit 100 acquires the progress information, the image output unit 101 prohibits outputting an image signal based on the mail data received from the mobile terminal 40 to the HUD 2.

  And if the own vehicle 80 is stopped again, the image output part 101 will output the image signal containing a 2nd mail image to HUD2. That is, when the stop information acquisition unit 100 acquires the stop information again, the image output unit 101 outputs an image signal including the second mail image to the HUD 2. Then, the occupant 90 visually recognizes the second mail virtual image 232.

  As described above, the image output unit 101 outputs the image signal that was output immediately before the host vehicle 80 was stopped and the host vehicle 80 was advanced when the host vehicle 80 was stopped this time. In other words, the image output unit 101 outputs an image signal when the stop information acquisition unit 100 acquires stop information. The image signal output by the image output unit 101 this time is the same signal as the image signal that was output when the progress information was acquired after the previous stop information was acquired.

  Next, a flow of a series of processes performed by the main ECU 1 in the present embodiment will be described with reference to FIG.

  The process of FIG. 7 is a process periodically performed by the main ECU 1 after the main ECU 1 is activated. In order to simplify the description, only the processing different from the processing performed by the main ECU 1 in the first embodiment will be described.

  In step S101, the stop information acquisition unit 100 determines whether stop information has been acquired or progress information has been acquired. When stop information is acquired, it progresses to step S102. Otherwise, the process proceeds to step S203. That is, when progress information is acquired, the process proceeds to step S203.

  In step S <b> 102, the image output unit 101 receives predetermined data from the mobile terminal 40. Thereafter, the process proceeds to step S201.

  In step S201, the image output unit 101 detects whether or not an image signal was output when the stop information acquisition unit 100 previously acquired the progress information. That is, the image output unit 101 detects whether or not an image signal was output immediately before the host vehicle 80 traveled last time. When the stop information acquisition unit 100 has previously acquired the progress information, if the image output unit 101 has output an image signal, the process proceeds to step S202; otherwise, the process proceeds to step S103.

  In step S202, the image output unit 101 outputs the image signal that was output when the stop information acquisition unit 100 previously acquired the progress information. That is, the image output unit 101 outputs the image signal that was output immediately before the host vehicle 80 traveled last time. Thereafter, the process ends.

  In step S <b> 103, the image output unit 101 detects whether or not new information is included in the predetermined data received from the mobile terminal 40. If new information is included in the predetermined data, the process proceeds to step S104, and if not, the process proceeds to step S203.

  In step S203, the image output unit 101 prohibits output of an image signal. Thereafter, the process ends.

  Hereinafter, effects of the main ECU 1 in the second embodiment will be described.

  The stop information acquisition unit 100 acquires progress information that is information related to the progress of the host vehicle 80. The image output unit 101 prohibits output of an image signal. Then, after the own vehicle 80 is advanced and output of the image signal is prohibited, the own vehicle 80 is stopped again, and the own vehicle 80 is used as an image signal when the image output unit 101 outputs the image signal again. This is the same as the image signal immediately before the recording.

  When the host vehicle 80 travels and the predetermined screen is displayed, the occupant 90 may be conscious of the predetermined screen and feel annoying. On the other hand, according to the above configuration, when the host vehicle advances, the image output unit 101 does not output an image signal to the HUD 2, so that the occupant can be less annoyed. Further, as described above, when the host vehicle 80 travels, the image output unit 101 does not output an image signal even while the occupant 90 is viewing the predetermined screen. Then, even if it is an image visually recognized by the occupant 90 last time, it must be visually recognized again from the first screen. On the other hand, if it is the said structure, since the passenger | crew 90 can restart visual recognition from the screen which was in the middle of visual recognition last time, the convenience improves.
