[0053] (Functional configuration of the display control ECU 28) The display control ECU 28 realizes various functions using the above hardware resources. The functional configuration realized by the display control ECU 28 will be described with reference to FIG. 4.

[0054] As shown in FIG. 4, the display control ECU 28 is configured to include a function acquisition unit 52, a display control unit 54, and a display screen setting unit 56 as its functional components. Each functional component is realized by the CPU 40A reading and executing a program stored in the ROM 40B or the storage 40D.

[0055] The function acquisition unit 52 acquires the ON and OFF states of various functions of the vehicle 12. In the vehicle 12, each of the vehicle control device 47, the ACC device 48, and each in-vehicle device 49 monitors the operating state of the control target. Also, when the vehicle control device 47, the ACC device 48, and each in-vehicle device 49 detect an event to be notified to the occupant in the control target, they generate information or an information image related to the detected event and output it to the display control ECU 28 via the system bus 43. In the present embodiment, the function acquisition unit 52 acquires whether the ACC function is in the ON state or the OFF state based on the ACC function ON signal input from the ACC device 48 to the display control ECU 28.

[0056] The display control unit 54 acquires information corresponding to the running state and operation state of the vehicle 12 via the system bus 43, and displays an image corresponding to the acquired information as a display screen in the display area V1 of the first display unit 24, and also displays it in the display area V2 of the second display unit 26 via the HUD 44. In the display control ECU 28, in the steady state of the vehicle 12, the information to be displayed in the display area V1 of the first display unit 24 and the format of the image for displaying the information are determined.

[0057] As shown in FIG. 5, the image 60 as the display screen displayed in the display area V1 of the first display unit 24 is substantially rectangular. The image 60 is an image indicating the engine speed, and a tachometer image 60A for indicating the engine speed is arranged in the central part. In the tachometer image 60A, narrow-scale scale bars 60B in an arc shape are arranged in the circumferential direction. And a colored numerical bar 60C indicating the current engine speed is arranged along the scale bar 60B, with the left end in the circumferential direction being 0 rpm and the numerical bar 60C corresponding to the engine speed The engine speed is displayed by the extension of the right end.

[0058] Also, in the image 60, the center part is the shift display part 60D. In the shift display part 60D, the shift position of the transmission is displayed, and the display is changed when the shift position of the transmission is changed. Further, in the image 60, the upper side of the shift display part 60D is the speed display part 60E, and the speed display part 60E displays a numerical value corresponding to the vehicle speed of the vehicle 12.

[0059] Furthermore, in the present embodiment, in the image 60, a rectangular display area 24A is disposed below the shift display part 60D. This display area 24A is set as a part of the display area V1 of the first display part 24, and the display control part 54 switches a plurality of display screens set by a display screen setting part 56 described later and causes them to be displayed in the display area 24A.

[0060] When the display control part 54 receives information or an information image regarding an event to be notified from the vehicle control device 47, the ACC device 48, and each in-vehicle device 49 of the vehicle 12, etc., based on the received information, it selects a display screen for display in the display area 24A from a plurality of display screens and causes it to be displayed in the display area 24A. The plurality of display screens are set by the display screen setting part 56 and are stored in, for example, the storage 40D.

[0061] Here, the plurality of display screens displayed in the display area 24A will be described. As shown in FIG. 6, as an example, the display screen setting part 56 sets the display screens including the display screens A1 to A4 and the blank screen B to be displayable in the display area 24A in order. The display screen A1 is Communication I A display screen on which drive information 1 for providing traffic information, road information, etc. received via / F40E is displayed. Display screen A2 is a display screen on which drive information 2 for providing fuel consumption information, etc. of vehicle 12 is displayed. Display screen A3 is a display screen on which an energy monitor for providing information indicating the relationship between tires, batteries, and energy is displayed. Display screen A4 is an audio status screen for providing the operating status of the audio. The blank screen B is a display screen composed of a black screen, etc. that is displayed when the user does not desire the display of various information in the display area 24A, etc.

[0062] A plurality of display screens including these display screens A1 to A4 and the blank screen B are sequentially switched by the display control unit 54 according to the operations of the UP switch 30A and the DOWN switch 30B and are displayed in the display area 24A. Specifically, when the UP switch 30A is operated, each time the UP switch 30A is operated once, the display screens are switched and displayed one page at a time from left to right in the order of display screen A1, display screen A2, display screen A3,... up to the final display screen. Conversely, when the DOWN switch 30B is operated, each time the DOWN switch 30B is operated once, the display screens are switched and displayed one page at a time from right to left in the order of blank screen B, display screen A4, display screen A3,... up to the initial display screen.

[0063] Note that when the display control unit 54 switches the display screen to be displayed in the display area 24A, when the UP switch 30A or the DOWN switch 30B is operated, it is dynamically switched and displayed so that each display screen flows continuously horizontally in the display area 24A. That is, during the process of completely switching the display screen, two display screens are displayed mixed in the display area 24A.

[0064] Further, when the UP switch 30A or the DOWN switch 30B is long-pressed, for example, the display control unit 54 continuously switches and displays a plurality of display screens in order until the long-press operation of the UP switch 30A or the DOWN switch 30B is released, and at the moment when the long-press operation of the UP switch 30A or the DOWN switch 30B is released, the display screen displayed in the display area 24A is displayed in the display area 24A as the selected display screen.

[0065] Also, when the function acquisition unit 52 acquires that the ACC function is in the ON state, the display control unit 54 inserts an ACC display screen for which information regarding the ACC function is provided as a specific display screen S into the plurality of display screens. In the present embodiment, for example, as shown in FIG. 7, the display control unit 54 inserts an ACC display screen as the specific display screen S between a first display screen M that was immediately previously displayed in the display area 24A and a second display screen M-1 that was displayed one step before (when the DOWN switch 30B was operated once).

[0066] The display screen setting unit 56 sets the ACC display screen as the inserted specific display screen S in the plurality of display screens. As shown in FIG. 8, for example, it is assumed that currently, a display screen A3 on which an energy monitor is displayed is being displayed in the display area 24A. In this case, the display control unit 54 inserts an 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 drive information 2 is displayed as the second display screen M-1 that is displayed one step 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,... up to the final display screen. That is, the total number of display screens to be managed increases by the display screen setting unit 56.

[0067] Furthermore, when the function acquisition unit 52 determines that the ACC function is in the OFF state When the above is acquired, the ACC display screen as the specific display screen S inserted into a plurality of display screens is deleted. 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 state).

[0068] (Display processing) Next, the vehicle display control process executed in the display control ECU 28 will be described using the flowcharts shown in FIGS. 9 and 10. This display control process is executed by the CPU 40A reading the display control program from the ROM 40B or the storage 40D and expanding it in the RAM 40C. Note that the following process is disclosed after an instruction to turn on the display screen of the display control ECU 28.

[0069] As shown in FIG. 9, 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) in step S11.

[0070] Next, the display control unit 54 determines whether there is an operation of the UP switch 30A or the DOWN switch 30B in step S12. If there is no operation (step S12; NO), the CPU 40A transfers the process to step S15. On the other hand, if there is an operation of the UP switch 30A or the DOWN switch 30B in step S12 (step S12; YES), the display control unit 54 performs switching display of the display screen displayed in the display area 24A according to the operation of the UP switch 30A or the DOWN switch 30B in step S14.

[0071] Next, the CPU 40A determines whether there is an instruction to turn off the display screen in step S15. If there is no instruction to turn off (step S15; NO), the CPU 40A transfers the process to step S12 and repeats the processes after step S12. On the other hand, if there is an instruction to turn off 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 a series of processes.

[0072] Also, 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, in parallel with the process of step S12, the display control unit 54 performs a display screen number change process in step S17.

[0073] As shown in FIG. 10, in step S21, the function acquisition unit 52 determines whether the ACC function has been turned on. If the ACC function has been turned on (step S21; YES), the display control unit 54 determines whether there is an ACC display screen as a specific display screen S among the plurality of 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 the specific display screen S into the plurality of display screens in step S23. Then, in step S24, the display screen setting unit 56 sets the inserted ACC display screen as the specific display screen S in the plurality of display screens. When a plurality of screens are set by the display screen setting unit 56, the display control unit 54 ends the display screen number change process and transfers the process to step S15 in FIG. 9. On the other hand, even if there is an ACC display screen in step S22 (step S22; YES), the display control unit 54 ends the display screen number change process and transfers the process to step S15 in FIG. 9.

[0075] Also, when the function acquisition unit 52 determines in step S21 that the ACC function is not ON (step S21; NO), in step S25, the function acquisition unit 52 determines whether the ACC function is OFF. If the ACC function is not OFF (step S25; NO), the display control unit 54 transfers the process to step S21 and repeats the processes after step S21. When the function acquisition unit 52 determines in step S25 that the ACC function is OFF (step S25; YES), the display control unit 54 determines in step S26 whether there is an ACC display screen as a specific display screen S among the plurality of display screens set by the display screen setting unit 56. If there is no ACC display screen (step S26; NO), the display control unit 54 ends the display screen number change process and transfers the process to step S15 in FIG. 9.

[0076]

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

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

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

[0080] ​In the display control ECU 28 as the vehicle display control device according to the present embodiment, a display control unit 54 is provided that switches and displays a plurality of display screens including information on various functions in the display area of the display unit, and changes the number of the plurality of display screens to be switched depending on whether the ACC function is ON or OFF. Therefore, in the state where 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 the display screen by the user can be simplified.

[0081] Also, in the display control ECU 28 as the vehicle display control device according to the present embodiment, when the ACC function is turned ON, the display control unit 54 inserts an ACC display screen as a specific display screen S for displaying information on the ACC function into a plurality of display screens. Therefore, when necessary, the necessary display screens can be increased, and an increase in unnecessary display screens can be suppressed.

[0082] Also, in the display control ECU 28 as the vehicle display control device according to the present embodiment, when the display control unit 54 displays the ACC display screen as the 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 immediately before displayed in the display area 24A and the second display screen M - 1 adjacent to the first display screen M before. Therefore, since the ACC display screen as the specific display screen S is adjacent to the first display screen M immediately before displayed, the trouble for the user to switch the display screen when displaying the ACC display screen as the specific display screen S can be reduced.

[0083] Also, in the display control ECU 28 as the vehicle display control device according to the present embodiment, the display control unit 54 continuously and dynamically switches a plurality of display screens and displays them in the display area 24A, so that the user can visually recognize the intermediate process of the display screen switching, and it can be made easier for the user to recognize that the display screen has been switched.

[0084] In addition, since the vehicle display device 10 according to the present embodiment includes the first display unit 24 and the display control ECU 28, the same operations and effects as those of the aforementioned display control ECU 28 can be obtained.

[0085] In addition, since the vehicle 12 according to the present embodiment includes the vehicle display device 10, the same operations and effects as those of the aforementioned display control ECU 28 can be obtained in the same manner as the vehicle display device 10.

[0086] In addition, the same operations and effects as those of the aforementioned display control ECU 28 can also be obtained in the vehicle display control method and the vehicle display control program according to the present embodiment.

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

[0088] As shown in FIG. 12, when the message tab screen AM is displayed in the display area 24A, when the function acquisition unit 52 acquires that the ACC function is in the ON state, the display control unit 54 sets the blank screen B immediately before the message tab screen AM in the display area 24A as the first display screen M, and the message tab screen AM as the second display screen M + 1 displayed one behind the blank screen B. The display control unit 54 inserts the ACC display screen as the 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 in a plurality of display screens.

[0089] In this way, since the ACC display screen AC as the specific display screen S can be made adjacent to the message tab screen AM, the labor of the user switching the display screen when the ACC display screen AC is displayed can be reduced.

[0090] Note that 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 immediately previously displayed in the display area 24A and the second display screen M-1 adjacent to the first display screen M in front. However, the present invention is not limited to this. For example, the ACC display screen may be inserted between the first display screen M immediately previously displayed in the display area 24A and the second display screen M+1 adjacent to the first display screen M behind. Also, the position of the specific display screen S to be inserted may be changed according to the display content 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 is displayed in the display area 24A for the longest time. In this case, the user can display the specific display screen S by simply operating the UP switch 30A or the DOWN switch 30B once from the display screen that the user is frequently looking at, so the labor of the user switching the display screen can be reduced.

[0091] Also, in the above embodiment, the ACC function is 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 a function of ADAS (Advanced Driver-Assistance Systems) such as the LKA (Lane-Keeping Assist) function executed by an LKA (Lane-Keeping Assist) device (not shown). The LKA function is a function that warns of the possibility of deviation from a lane or a road and supports a part of the steering operation to avoid deviation from the lane or the road. In this case, the specific display screen S becomes an LKA display screen including information related to the LKA function.

[0092] In addition, when the function acquisition unit 52 acquires both the ON and OFF states of the ACC function and the LKA function as specific functions of the 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 the corresponding function when each function becomes ON.

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

[0094] Also, in the above embodiment described above, as shown in FIG. 6, the vehicle 12 in which an energy monitor for providing information indicating the relationship between the tire, the battery, and the energy is displayed in the display area 24A is a hybrid vehicle (HEV: Hybrid Electric Vehicle), a plug -in hybrid vehicle (PHEV: Plug-in Hybrid Electric Vehicle), etc. are taken as examples. . However, the vehicle 12 may be a fuel cell vehicle (FCEV: Fuel Cell Electric Vehicle), a battery electric vehicle (BEV: Battery Electric Vehicle), etc. Also, the vehicle 12 may 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, instead of the display screen A3 on which the energy monitor is displayed, for example, a display screen on which eco-drive information is displayed can be displayed. Note that the display control ECU 28 may perform the display set according to the vehicle mounted.

[0095] Also, each process that the CPU 40A shown in FIG. 3 in the present embodiment reads and executes the software (program) may be executed by various processors other than the CPU. Examples of the processor in this case include a PLD (Programmable Logic Device) whose circuit configuration can be changed after manufacture, such as an FPGA (Field-Programmable Gate Array), and a dedicated electric circuit which is a processor having a circuit configuration designed specifically for executing specific processes, such as an ASIC (Application Specific Integrated Circuit). Further, 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 type or different types (for example, a plurality of FPGAs, a combination of a CPU and an FPGA, etc.). More specifically, the hardware structure of these various processors is an electric circuit combining circuit elements such as semiconductor elements.

[0096] Also, 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), and a USB (Universal Serial Bus) memory. Further, the program may be in a form downloaded from an external device via a network.

[0097] As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above, and it goes without saying that various modifications other than the above can be made and implemented within the scope not departing from the gist of the present invention.
