[0063] When switching the display screen displayed in the display area 24A, the display control unit 54 dynamically switches and displays each display screen so that the screens flow continuously in the horizontal direction in the display area 24A when the UP switch 30A or the DOWN switch 30B is operated. That is, in the middle of switching the display screen completely, two display screens are displayed in the display area 24A in a mixed manner.

[0064] In addition, when the UP switch 30A or the DOWN switch 30B is pressed and held, as an example, the display control unit 54 continues to switch and display multiple display screens in sequence until the long press of the UP switch 30A or the DOWN switch 30B is released, and displays in the display area 24A the display screen that is being displayed at the time the long press of the UP switch 30A or the DOWN switch 30B is released as the selected display screen.

[0065] Furthermore, when the display control unit 54 acquires from the function acquisition unit 52 that the ACC function is in an ON state, the display control unit 54 inserts an ACC display screen, on which information related to the ACC function is provided, into the above-mentioned multiple display screens as a specific display screen S. In the present embodiment, as an example, as shown in Fig. 7, the display control unit 54 inserts the ACC display screen as a specific display screen S between a first display screen M that is displayed immediately before in the display area 24A and a second display screen M-1 that is displayed immediately before (displayed when the DOWN switch 30B is operated once).

[0066] The display screen setting unit 56 sets the ACC display screen as the inserted specific display screen S to a plurality of display screens. As shown in FIG. 8, as an example, it is assumed that the display screen A3 on which the energy monitor is displayed is currently displayed in the display area 24A. In this case, the display control unit 54 inserts the ACC display screen as the specific display screen S between the display screen A3 as the first display screen M and the display screen A2 on which the drive information 2 is displayed as the second display screen M-1 displayed immediately before the display screen A3. As a result, the display screen setting unit 56 sets the display screens so that the display screens are switched and displayed one page at a time from left to right in the order of the display screen A1, the display screen A2, the specific display screen S, the display screen A3, . . . until the final display screen. That is, the total number of display screens managed by the display screen setting unit 56 increases.

[0067] Furthermore, when the display control unit 54 acquires from the function acquisition unit 52 that the ACC function is in an OFF state, it deletes the ACC display screen as the specific display screen S that was inserted into the multiple display screens. As a result, the display screen setting unit 56 returns to the setting of the display screen in the steady state of the vehicle 12 shown in Fig. 6. That is, the total number of display screens managed by the display screen setting unit 56 decreases (returns to the original number).

[0068] (Display processing) Next, the vehicle display control process executed in the display control ECU 28 will be described with reference to the flowcharts shown in Figures 9 and 10. This display control process is executed by the CPU 40A reading out a display control program from the ROM 40B or storage 40D, and developing and executing the program in the RAM 40C. Note that the following process is started after an instruction to turn on the display screen of the display control ECU 28 is given.

[0069] As shown in FIG. 9, in step S11, the display control ECU 28 turns on the display screen (display area V1) of the first display unit 24 and the head-up display device 44 (display area V2).

[0070] Next, the display control unit 54 determines whether or not the UP switch 30A or the DOWN switch 30B has been operated in step S12. If there has been no operation (step S12; NO), the CPU 40A proceeds to step S15. On the other hand, if the UP switch 30A or the DOWN switch 30B has been operated in step S12 (step S12; YES), the display control unit 54 switches the display screen displayed in the display area 24A in response to the operation of the UP switch 30A or the DOWN switch 30B in step S14.

[0071] Next, the CPU 40A determines whether or not there is an instruction to turn off the display screen in step S15. If there is no instruction to turn off the display screen (step S15; NO), the CPU 40A proceeds to step S12 and repeats the processing from step S12 onward. On the other hand, if there is an instruction to turn off the display screen in step S15 (step S15; YES), the display control ECU 28 turns off the display screen (display area V1) of the first display unit 24 and the head-up display device 44 (display area V2) in step S16, and ends the series of processing.

[0072] Furthermore, when the display screen (display area V1) of the first display unit 24 and the head-up display device 44 (display area V2) are turned ON in step S11, the display control unit 54 performs a process of changing the number of display screens in step S17 in parallel with the process of step S12.

[0073] 10, in step S21, the function acquisition unit 52 determines whether or not the ACC function is turned ON. If the ACC function is turned ON (step S21; YES), the display control unit 54 determines whether or not there is an ACC display screen as a specific display screen S among the multiple display screens set by the display screen setting unit 56 in step S22.

[0074] If there is no ACC display screen (step S22; NO), the display control unit 54 inserts the ACC display screen as a specific display screen S into the multiple display screens in step S23. Then, in step S24, the display screen setting unit 56 sets the ACC display screen as the inserted specific display screen S into the multiple display screens. When the multiple screens are set by the display screen setting unit 56, the display control unit 54 ends the display screen number change process and shifts the process to step S15 in Fig. 9. On the other hand, if there is an ACC display screen in step S22 (step S22; YES), the display control unit 54 also ends the display screen number change process and shifts the process to step S15 in Fig. 9.

[0075] If the function acquisition unit 52 determines in step S21 that the ACC function is not turned ON (step S21; NO), the function acquisition unit 52 determines in step S25 whether the ACC function is turned OFF. If the ACC function is not turned OFF (step S25; NO), the display control unit 54 transitions to the process in step S21 and repeats the process in and after step S21.

[0076] On the other hand, when the function acquisition unit 52 determines in step S25 that the ACC function has been turned OFF (step S25; YES), the display control unit 54 determines in step S26 whether or not there is an ACC display screen as the specific display screen S among the multiple display screens set by the display screen setting unit 56. When there is no ACC display screen (step S26; NO), the display control unit 54 ends the display screen number change process and proceeds to step S15 in FIG.

[0077] In step S26, if there is an ACC display screen (step S26; YES), the display control unit 54 deletes the ACC display screen as the specific display screen S from the multiple display screens in step S27. Then, in step S24, the display screen setting unit 56 sets the multiple display screens from which the ACC display screen as the specific display screen S has been deleted as the multiple display screens to be displayed in the display area 24A. When the multiple screens are set by the display screen setting unit 56, the display control unit 54 ends the display screen number change process and proceeds to step S15 in FIG. 9.

[0078] In this manner, the number of display screens displayed in the display area 24A is changed depending on whether the ACC function is ON or OFF, through the display screen number changing process by the display control unit 54 in step S17.

[0079] (Action and effect) Next, the effects of this embodiment will be described.

[0080] The display control ECU 28 as a vehicle display control device according to this embodiment switches between a plurality of display screens including information on various functions and displays them in the display area of ​​the display unit, and includes a display control unit 54 that changes the number of the plurality of display screens to be switched between depending on whether the ACC function is ON or OFF. Therefore, when the ACC function is OFF, the number of the plurality of display screens to be switched can be reduced, and by reducing unnecessary display screens, the selection of a display screen by the user can be simplified.

[0081] In addition, in the display control ECU 28 as the vehicle display control device according to this embodiment, when the ACC function is turned ON, the display control unit 54 inserts an ACC display screen as a specific display screen S that displays information related to the ACC function into multiple display screens. Therefore, it is possible to increase the number of display screens as needed, thereby suppressing an increase in unnecessary display screens.

[0082] Furthermore, in the display control ECU 28 serving as the vehicle display control device according to this embodiment, when the display control unit 54 displays an ACC display screen as a specific display screen S in the display area 24A, the display control unit 54 inserts the ACC display screen as the specific display screen S between the first display screen M displayed immediately before in the display area 24A and the second display screen M-1 adjacent and in front of the first display screen M. Therefore, since the ACC display screen as the specific display screen S is adjacent to the first display screen M displayed immediately before, it is possible to reduce the effort required for the user to switch display screens when displaying the ACC display screen as the specific display screen S.

[0083] Furthermore, in the display control ECU 28 serving as a vehicle display control device in this embodiment, the display control unit 54 continuously and dynamically switches between multiple display screens and displays them in the display area 24A, allowing the user to visually check the progress of the display screen switching, making it easier for the user to recognize that the display screen has been switched.

[0084] Furthermore, since the vehicle display device 10 according to this embodiment includes the first display unit 24 and the display control ECU 28, the same actions and effects as those of the display control ECU 28 described above can be obtained.

[0085] Furthermore, since the vehicle 12 according to this embodiment includes the vehicle display device 10, the same actions and effects as those of the above-mentioned display control ECU 28 can be obtained, similarly to the vehicle display device 10.

[0086] In addition, the vehicle display control method and the vehicle display control program according to this embodiment also provide the same functions and effects as those of the display control ECU 28 described above.

[0087] (First Modification) The first modified example is an example of inserting an ACC display screen as a specific display screen S into a plurality of display screens when a message tab screen AM is displayed in the display area 24A. Here, the message tab screen AM is a warning display screen for an irregular event such as "The oil is dirty, so please go to a dealer to have it changed." As shown in FIG. 11, the message tab screen AM is usually inserted adjacent to the blank screen B.

[0088] 12, when the message tab screen AM is displayed in the display area 24A, upon acquiring by the function acquisition unit 52 that the ACC function is ON, the display control unit 54 sets the blank screen B displayed immediately before the message tab screen AM in the display area 24A as the first display screen M, and sets the message tab screen AM as the second display screen M+1 displayed one screen behind the blank screen B. The display control unit 54 inserts an ACC display screen as a specific display screen S between the first display screen M and the second display screen M+1. Then, the display screen setting unit 56 sets the inserted ACC display screen as the specific display screen S to a plurality of display screens.

[0089] In this way, since the ACC display screen AC as the specific display screen S can be adjacent to the message tab screen AM, the user does not have to go through the trouble of switching the display screen when displaying the ACC display screen AC.

[0090] In the above embodiment, as shown in FIG. 7, when the display control unit 54 displays the ACC display screen as the specific display screen S in the display area 24A, the ACC display screen is inserted between the first display screen M displayed immediately before in the display area 24A and the second display screen M-1 adjacent to and in front of the first display screen M, but the present invention is not limited to this. For example, the ACC display screen may be inserted between the first display screen M displayed immediately before in the display area 24A and the second display screen M+1 adjacent to and behind the first display screen M. In addition, the position of the specific display screen S to be inserted may be changed depending on the display contents of the display screen displayed in the display area 24A. As an example, the specific display screen S may be inserted at a position adjacent to the display screen that has been displayed for the longest time in the display area 24A. In this case, the user can display the specific display screen S by simply operating the UP switch 30A or the DOWN switch 30B from the display screen that the user frequently views, thereby reducing the effort required for the user to switch the display screen.

[0091] In the above embodiment, the ACC function has been described as an example of the specific function, but the specific function of the present invention is not limited to the ACC function. For example, the specific function may be an ADAS (Advanced Driver-Assistance Systems) function such as an LKA (Lane Keeping Assist) function executed by an LKA device (not shown). The LKA function is a function that warns of the possibility of deviation from a lane or road and assists in part of the steering operation to avoid deviation from the lane or road. In this case, the specific display screen S is an LKA display screen including information related to the LKA function.

[0092] In addition, when the function acquisition unit 52 acquires the ON and OFF of both the ACC function and the LKA function as a specific function, the specific display screen S becomes both the ACC display screen and the LKA display screen, and the display control unit 54 can insert the display screen of each function when it is turned ON.

[0093] Further, in the above embodiment, the display example of the display region V1 has been described, but the present invention is not limited to this, and the display region 24A may be provided in the display region V2.

[0094] In the above-described embodiment, as shown in FIG. 6, a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), etc. are taken as examples of the vehicle 12 in which an energy monitor for providing information showing the relationship between tires, a battery, and energy is displayed in the display area 24A. However, the vehicle 12 may be a fuel cell electric vehicle (FCEV) or an electric vehicle (BEV) or the like. The vehicle 12 may also be a vehicle equipped with an engine (reciprocating engine) as a driving source for traveling. In the case of a vehicle equipped with an engine, a display screen that displays, for example, eco-driving information can be displayed instead of the display screen A3 on which the energy monitor is displayed. The display control ECU 28 may perform a display set according to the vehicle in which it is installed.

[0095] In addition, various processors other than the CPU may execute each process executed by the CPU 40A shown in FIG. 3 by reading the software (program) in this embodiment. In this case, examples of the processor include a PLD (Programmable Logic Device) such as an FPGA (Field-Programmable Gate Array) whose circuit configuration can be changed after manufacture, and a dedicated electric circuit such as an ASIC (Application Specific Integrated Circuit) which is a processor having a circuit configuration designed exclusively for executing a specific process. Each process may be executed by one of these various processors, or may be executed by a combination of two or more processors of the same or different types (for example, a plurality of FPGAs, and a combination of a CPU and an FPGA). The hardware structure of these various processors is, more specifically, an electric circuit that combines circuit elements such as semiconductor elements.

[0096] Furthermore, each program described in the present embodiment may be provided in a form recorded on a recording medium such as a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM (Digital Versatile Disc Read Only Memory), a USB (Universal Serial Bus) memory, etc. Furthermore, the programs may be provided in a form downloaded from an external device via a network.

[0097] Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and it is of course possible to implement the present invention in various other modified forms without departing from the spirit and scope of the present invention.
