Furthermore, turn signal switches 30 are provided on the spoke portion 16C on the right side of the hub portion 16B in the vehicle width direction and on the spoke portion 16C on the left side of the hub portion 16B in the vehicle width direction. However, for simplicity, only the turn signal switch 30 on the right side of the hub portion 16B in the vehicle width direction will be described in detail here. The turn signal switch 30 on the left side of the hub portion 16B in the vehicle width direction can also have the same function as the turn signal switch 30 on the right side of the hub portion 16B in the vehicle width direction. Furthermore, the turn signal switch 30 can be selected as a switch operable only on either the right or left side of the hub portion 16B in the vehicle width direction, or it can be selected as a switch operable on both sides.

[0046] like Figure 2 As shown, the turn signal switch 30 includes a hub portion 16B on the side (with...) Figure 1 The right second operating switch 36R and the rim 16A side (corresponding to the left side of the paper) are located on the left side of the paper. Figure 1 The right first operating switch 34R (corresponding to the right side of the paper), and the right first operating switch 34R and the right second operating switch 36R are, for example, contact detection type.

[0047] In this embodiment, the right first operation switch 34R is a switch assigned for switching the display screen as described later.

[0048] In addition, such as Figure 1 As shown, a windshield 17 is provided at the front end of the dashboard 14. The windshield 17 extends in the vertical direction and the width direction of the vehicle to divide the interior and exterior of the passenger compartment.

[0049] The windshield 17 is fixed to the right front pillar 18 of the vehicle. The front pillar 18 extends in the vertical direction of the vehicle, and the windshield 17 is fixed to the inner end of the front pillar 18 in the vehicle width direction. In addition, the front end of the front side window 19 is fixed to the outer end of the front pillar 18 in the vehicle width direction. Furthermore, the windshield 17 is fixed to the left front pillar of the vehicle.

[0050] Here, a first display unit (first display) 24 with an image display area V1 is provided on the instrument panel 14. The image display area V1 is composed of an instrument display located on the right side of the instrument panel 14 in front of the driver's seat. The first display unit 24 is connected to various instrument devices mounted on the vehicle 12, and the display area V1 is positioned to enter the driver's field of vision when the driver's gaze is directed forward.

[0051] A second display unit (second display) 26 with an image display area V2 is provided on the windshield 17. The display area V2 is located on the vehicle-top side of the display area V1, and the display area V2 is connected to a head-up display device 44 (see reference). Figure 3 The projection surface of the projection is configured. Specifically, a head-up display device 44 is provided on the front side of the instrument panel 14, configured to project an image from the head-up display device 44 onto the display area V2 of the second display section 26 of the windshield 17. That is, the display area V2 is a part of the windshield 17, which serves as the projection surface of the head-up display device 44.

[0052] (Hardware structure of vehicle display device 10)

[0053] The vehicle 12 is equipped with a control unit, namely a display control ECU (Electronic Control Unit), which serves as a vehicle display device 10. Figure 3 This is a block diagram showing the hardware structure of the vehicle display device 10.

[0054] Such as Figure 3As shown, the display control ECU 28 of the vehicle display device 10 is configured to include a CPU (Central Processing Unit) 40A, a ROM (Read Only Memory) 40B, a RAM (Random Access Memory) 40C, a storage device 40D, a communication interface (communication I / F) 40E, and an input / output interface (input / output I / F) 40F. All components are communicatively connected to each other via a bus 42.

[0055] As an example of a hardware processor, CPU 40A is a central processing unit that executes various programs and controls various components. Specifically, CPU 40A loads programs from ROM 40B or storage device 40D (examples of memory) and executes the programs using RAM 40C as the working area. CPU 40A performs control and various arithmetic operations on the aforementioned structures based on the programs recorded in ROM 40B or storage device 40D.

[0056] ROM 40B stores various programs and data. RAM 40C temporarily stores programs or data as a working area. Storage device 40D is composed of HDD (Hard Disk Drive) or SSD (Solid State Drive) and stores various programs and data, including the operating system. In this embodiment, ROM 40B or storage device 40D stores programs and various data for display processing.

[0057] The Communication I / F40E is an interface used for communication between the vehicle display device 10 and servers and other devices, such as using standards like Ethernet (registered trademark), LTE, FDDI, and Wi-Fi (registered trademark).

[0058] A first display unit 24 and a head-up display device (HUD) 44 are connected to the input / output I / F 40F. Images are projected onto the display area V2 of the second display unit 26 via the head-up display device 44.

[0059] In addition, the input / output I / O 40F is connected to the system bus 43 equipped in the vehicle 12. The system bus 43 is connected to the switch control device 46, the vehicle control device 47, the ACC (Adaptive Cruise Control) device 48, and the on-board equipment 49, etc.

[0060] The switch control device 46 is connected to various switches, including the turn signal switch 30, which serve as selection and setting mechanisms, and controls the inputs from these switches. In this embodiment, the switch control device 46 detects the operating status of the turn signal switches 30 (up switch 30A and down switch 30B) and outputs it to the display control ECU 28 via the system bus 43.

[0061] The vehicle control unit 47 is equipped with various control ECUs, including a vehicle control ECU responsible for vehicle control (including driving control), an engine ECU for engine control, a steering control ECU for steering control, a brake control ECU for braking control, and a transmission control ECU for transmission control. The vehicle control unit 47 works in conjunction with each control ECU to perform actions and control the driving of the vehicle 12.

[0062] The ACC device 48 is a device that enables the maintenance of vehicle speed and distance from the vehicle in front (ACC function) as a driving assistance function to maintain a safe distance from the vehicle ahead. In addition, in the vehicle 12, the ACC device 48 may also be configured to cooperate with the vehicle control device 47 to act as a driving assistance device to realize a driving assistance function to assist the occupants in driving operations.

[0063] The vehicle-mounted equipment 49 includes various devices such as air conditioning, audio systems, vehicle navigation systems, and voice input systems, as well as various sensor devices such as cameras, radar, light detection and ranging (LIDAR; Light Detection and Ranging or Laser Imaging Detection and Ranging), and GPS (global positioning system) sensors, and various other devices mounted on the vehicle 12.

[0064] (Functional structure of display control ECU28)

[0065] The display control ECU28 uses the aforementioned hardware resources to implement various functions. (Refer to...) Figure 4 The functional structure of the display control ECU28 is explained.

[0066] like Figure 4 As shown, 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 structure. Furthermore, each functional structure is implemented by the CPU 40A reading and executing a program stored in the ROM 40B or the storage device 40D.

[0067] The function acquisition unit 52 acquires the activation and deactivation of various functions of the vehicle 12. In the vehicle 12, the vehicle control unit 47, the ACC device 48, and various on-board devices 49 monitor the operational status of the controlled objects. Furthermore, if the vehicle control unit 47, the ACC device 48, and the various on-board devices 49 detect a phenomenon in the controlled objects that should be reported to the occupants, they generate information or an information image about the detected phenomenon and output it to the display control ECU 28 via the system bus 43. In this embodiment, the function acquisition unit 52 acquires whether the ACC function is activated or deactivated based on the ACC function activation signal input from the ACC device 48 to the display control ECU 28.

[0068] The display control unit 54 acquires information corresponding to the driving and operating states of the vehicle 12 via the system bus 43, displays the image corresponding to the acquired information as a display screen in the display area V1 of the first display unit 24, and displays it in the display area V2 of the second display unit 26 via the HUD 44. For the display control ECU 28, under normal conditions of the vehicle 12, the information displayed in the display area V1 of the first display unit 24 and the format of the image used to display that information are fixed.

[0069] like Figure 5 As shown, the image 60 displayed in the display area V1 of the first display unit 24 is approximately rectangular. Image 60 represents the engine speed, and a tachometer image 60A for representing the engine speed is arranged in the center. In the tachometer image 60A, there are arc-shaped, narrow scale bars 60B arranged circumferentially. Furthermore, a colored numerical bar 60C representing the current engine speed is arranged along the scale bars 60B, with the left end of the circumferential direction set as 0 rpm and the right end of the numerical bar 60C extending according to the engine speed, thereby displaying the engine speed.

[0070] Additionally, in image 60, the center section is a shift display unit 60D, which displays the shift position of the transmission. The display changes by changing the shift position of the transmission. Furthermore, in image 60, above the shift display unit 60D is a speed display unit 60E, which displays a value corresponding to the vehicle speed of vehicle 12.

[0071] Furthermore, in this embodiment, in image 60, a rectangular display area 24A is provided below the gear shift display unit 60D. This display area 24A is set in a portion of the display area V1 of the first display unit 24, and the display control unit 54 switches between multiple display screens set by the display screen setting unit 56 (described later) and displays them in the display area 24A.

[0072] If the display control unit 54 receives information or information images about a reportable phenomenon from the vehicle control device 47, ACC device 48, and various in-vehicle devices 49 of the vehicle 12, it selects a display screen from multiple display screens to display in the display area 24A based on the received information, and displays it in the display area 24A. The multiple display screens are set by the display screen setting unit 56, for example, and stored in the storage device 40D.

[0073] This section describes the multiple display screens shown in display area 24A. For example... Figure 6 As shown, for example, the display screen setting unit 56 is configured to sequentially display display screens, including display screens A1 to A4 and blank screen B, on display area 24A. Display screen A1 displays driving information 1, such as traffic information and road information received via communication I / F40E. Display screen A2 displays driving information 2, such as fuel consumption information of vehicle 12. Display screen A3 displays energy monitoring information, such as information on the relationship between tires, battery, and energy. Display screen A4 displays audio status information, such as the operating status of the audio system. Blank screen B is a display screen consisting of a black screen or the like, displayed when the user does not want various information to be displayed on display area 24A.

[0074] Based on the operation of the up switch 30A and the down switch 30B, the display control unit 54 sequentially switches between multiple display screens, including display screens A1 to A4 and blank screen B, and displays them in the display area 24A. Specifically, each operation of the up switch 30A switches the display screens one by one from left to right in the order of display screen A1, display screen A2, display screen A3, ... until the final display screen is reached. Conversely, each operation of the down switch 30B switches the display screens one by one from right to left in the order of blank screen B, display screen A4, display screen A3, ... until the initial display screen is reached.

[0075] Furthermore, when switching between display screens in display area 24A, the display control unit 54 dynamically switches between each display screen in a manner that allows the display screens to flow continuously horizontally within display area 24A when the up switch 30A or the down switch 30B is operated. That is, during the complete switching of display screens, two display screens are displayed in display area 24A.

[0076] In addition, when the up switch 30A or down switch 30B is pressed and held, for example, until the long press operation of the up switch 30A or down switch 30B is released, the display control unit 54 sequentially switches multiple display screens to continuously display, and displays the display screen that was displayed in the display area 24A at the moment when the long press operation of the up switch 30A or down switch 30B was released as the selected display screen in the display area 24A.

[0077] Furthermore, when the function acquisition unit 52 obtains that the ACC function is enabled, the display control unit 54 inserts an ACC display screen, which provides information about the ACC function, as a specific display screen S into the aforementioned plurality of display screens. In this embodiment, as an example, such as Figure 7 As shown, the display control unit 54 inserts the ACC display screen, which is a specific display screen S, between the first display screen M that was just displayed in the display area 24A and the second display screen M-1 that was the previous display (displayed when the down switch 30B is operated once).

[0078] The display screen setting unit 56 sets the ACC display screen, which is the specific display screen S inserted, to multiple display screens. For example... Figure 8 As shown, assuming that display screen A3, which displays energy monitoring information, is currently displayed in display area 24A, the display control unit 54 inserts the ACC display screen as a specific display screen S between display screen A3, which is the first display screen M, and display screen A2, which displays driving information 2, and is the second display screen M-1 displayed before display screen A3. As a result, the display screen setting unit 56 sets the display screens so that the display screens are switched one page at a time from left to right in the order of display screen A1, display screen A2, specific display screen S, 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.

[0079] Furthermore, when the function acquisition unit 52 determines that the ACC function is off, the display control unit 54 deletes the ACC display screen that was inserted into the multiple display screens as a specific display screen S. As a result, the display screen setting unit 56 returns to... Figure 6 The display screen settings for the vehicle 12 in its normal state are shown. That is, the total number of managed display screens is reduced (returned to the original state) by the display screen setting unit 56.

[0080] (Display processing)

[0081] Next, use Figure 9 and Figure 10The flowchart shown illustrates the vehicle display control processing executed by the display control ECU 28. The display control process is executed by loading the display control program from ROM 40B or storage device 40D via CPU 40A and then executing it in RAM 40C. Furthermore, the following processing begins after an instruction to the display control ECU 28 that the display screen is on.

[0082] like Figure 9 As shown, in step S11, the display control ECU28 turns on the display screen (display area V1) of the first display unit 24 and the head-up display device 44 (display area V2).

[0083] Next, the display control unit 54 determines in step S12 whether there is an operation to raise switch 30A or lower switch 30B. If there is no operation (step S12: No), the CPU 40A moves the processing to step S15. On the other hand, if there is an operation to raise switch 30A or lower switch 30B in step S12 (step S12: Yes), the display control unit 54 switches the display screen displayed in the display area 24A according to the operation of raising switch 30A or lowering switch 30B in step S14.

[0084] Next, in step S15, the CPU 40A determines whether there is an instruction to turn off the display screen. If there is no instruction to turn it off (step S15: No), the CPU 40A moves the processing to step S12 and repeats the processing after step S12. On the other hand, if there is an instruction to turn it 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 the series of processes.

[0085] In addition, if 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 the display screen number change processing in step S17 in parallel with the processing in step S12.

[0086] like Figure 10 As shown, in step S21, the function acquisition unit 52 determines whether the ACC function is enabled. If the ACC function is enabled (step S21: Yes), the display control unit 54 determines in step S22 whether 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.

[0087] 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 multiple display screens in step S23. Furthermore, in step S24, the display screen setting unit 56 sets the ACC display screen as the inserted specific display screen S into multiple display screens. If multiple screens are set by the display screen setting unit 56, the display control unit 54 ends the display screen number change process and moves the processing to... Figure 9 Step S15. On the other hand, when there is an ACC display screen in step S22 (step S22: Yes), the display control unit 54 also ends the display screen number change processing and moves the processing to Figure 9 Step S15.

[0088] Furthermore, if the function acquisition unit 52 determines in step S21 that the ACC function has not been 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 moves the processing back to step S21 and repeats the processing after step S21.

[0089] 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 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. If there is no ACC display screen (step S26: No), the display control unit 54 ends the display screen number change process and moves the processing to Figure 9 Step S15.

[0090] If an ACC display screen is present in step S26 (step S26: Yes), the display control unit 54 removes the ACC display screen, which is a specific display screen S, from the multiple display screens in step S27. Furthermore, in step S24, the display screen setting unit 56 sets the multiple display screens, from which the ACC display screen, which was removed as a specific display screen S, to the multiple display screens displayed in the display area 24A. If the display screen setting unit 56 sets multiple screens, the display control unit 54 ends the display screen number change process and moves the processing to... Figure 9 Step S15.

[0091] Thus, by performing the display screen number change processing in step S17 by the display control unit 54, the number of multiple display screens displayed in the display area 24A is changed whether the ACC function is on or off.

[0092] (Effects)

[0093] Next, the effects of this implementation method will be explained.

[0094] The display control ECU28, which is the vehicle display control device according to this embodiment, includes a display control unit 54. This display control unit 54 switches between multiple display screens, including information about various functions, and displays them on the display area of ​​the display unit. Furthermore, the number of multiple display screens switched between is changed depending on whether the ACC function is on or off. Therefore, the number of multiple display screens switched between can be reduced when the ACC function is off, thus simplifying the user's selection of display screens by reducing unnecessary display screens.

[0095] Furthermore, in the display control ECU28, which is 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, which is a specific display screen S displaying information about the ACC function, into multiple display screens. Therefore, it is possible to add the required display screens when needed, and thus it is possible to suppress the addition of unnecessary display screens.

[0096] Furthermore, in the display control ECU 28, which is the vehicle display control device according to this embodiment, when the ACC display screen, which is a specific display screen S, is displayed in the display area 24A, the display control unit 54 inserts the ACC display screen, which is the specific display screen S, between the first display screen M, which was just displayed in the display area 24A, and the second display screen M-1, which is adjacent to the first display screen M. Therefore, since the ACC display screen, which is the specific display screen S, is adjacent to the first display screen M, the inconvenience of switching display screens when the ACC display screen, which is the specific display screen S, is displayed can be reduced.

[0097] Furthermore, in the display control ECU28, which is the vehicle display control device according to this embodiment, the display control unit 54 continuously and dynamically switches multiple display screens to display in the display area 24A. Therefore, the user can visually identify the transition of the display screens and thus easily recognize the situation where the display screens have been switched.

[0098] Furthermore, the vehicle display device 10 according to this embodiment includes a first display unit 24 and a display control ECU 28, thus achieving the same function and effect as the display control ECU 28 described above.

[0099] In addition, the vehicle 12 involved in this embodiment is equipped with a vehicle display device 10, and therefore, like the vehicle display device 10, it can obtain the same function and effect as the display control ECU 28 described above.

[0100] Furthermore, the same function and effect as the above-described display control ECU28 can also be obtained in the vehicle display control method and vehicle display control program involved in this embodiment.

[0101] (First variation)

[0102] The first variation is an example where, when a message label screen AM is displayed in display area 24A, the ACC display screen, which is a specific display screen S, is inserted into multiple display screens. Here, the message label screen AM is, for example, a warning display screen indicating an abnormal phenomenon, such as "Due to oil contamination, please go to the dealer for oil change." Figure 11 As shown, the message tag screen AM is usually inserted adjacent to the blank screen B.

[0103] like Figure 12 As shown, when the message tag screen AM is displayed in the display area 24A, and the function acquisition unit 52 obtains that the ACC function is enabled, the display control unit 54 designates the blank screen B that was just displayed in the display area 24A before the message tag screen AM as the first display screen M, and designates the message tag screen AM as the second display screen M+1 that is displayed after the blank screen B. The display control unit 54 inserts the ACC display screen as a specific display screen S between the first display screen M and the second display screen M+1. Furthermore, the display screen setting unit 56 sets the ACC display screen as the inserted specific display screen S on multiple display screens.

[0104] In this way, the ACC display screen AC, which is a specific display screen S, can be adjacent to the message tag screen AM, thus reducing the trouble for users to switch display screens when the ACC display screen AC is displayed.

[0105] Furthermore, in the above embodiments, such as Figure 7As shown, when the ACC display screen, which is a specific display screen S, is displayed in the display area 24A, the display control unit 54 inserts the ACC display screen between the first display screen M that was just displayed in the display area 24A and the second display screen M-1 that is adjacent to the first display screen M. However, this disclosure is not limited to this. For example, the ACC display screen may also be inserted between the first display screen M that was just displayed in the display area 24A and the second display screen M+1 that is adjacent to the first display screen M. In addition, the position of the inserted specific display screen S may be changed according to the display content of the display screens displayed in the display area 24A. As an example, the specific display screen S may also be inserted in a position adjacent to the longest display screen displayed in the display area 24A. In this case, the user can display the specific display screen S by performing an operation on the up switch 30A or the down switch 30B from the display screen that is frequently seen, thus reducing the trouble for the user to switch display screens.

[0106] Furthermore, in the above embodiments, a specific function was described using the ACC function as an example, but the specific function disclosed herein is not limited to the ACC function. For example, the specific function may also be an ADAS (Advanced Driver-Assistance Systems) function such as the LKA (Lane Keeping Assist) function performed by the LKA (Lane Keeping Assist) device. The LKA function is a function that warns of the possibility of leaving the lane or runway and assists in the operation of the handle to avoid leaving the lane or runway. In this case, the specific display screen S becomes the LKA display screen, which includes information about the LKA function.

[0107] Furthermore, when the function acquisition unit 52 acquires the on / off status of both the ACC function and the LKA function, which are specific functions, the specific display screen S consists of both the ACC display screen and the LKA display screen. The display control unit 54 can insert the display screen of each function when each function becomes on.

[0108] Furthermore, the above embodiment describes a display example of display area V1, but it is not limited to this; display area 24A may also be set in display area V2.

[0109] Furthermore, in the embodiments described above, such as Figure 6As shown, a hybrid electric vehicle (HEV) or a plug-in hybrid electric vehicle (PHEV) will be used as an example of a vehicle 12 that displays energy monitoring information in display area 24A to provide information on the relationship between tires, battery, and energy. However, vehicle 12 could also be a fuel cell electric vehicle (FCEV) or a battery electric vehicle (BEV). Additionally, vehicle 12 could be a vehicle equipped with an engine (reciprocating engine) as its driving source. In the case of a vehicle equipped with an engine, for example, a display screen showing eco-friendly driving information can be displayed instead of the energy monitoring display screen A3. Furthermore, the display control ECU 28 only needs to perform the display settings according to the vehicle it is equipped with.

[0110] Alternatively, in this embodiment, it can also be executed by various processors other than the CPU. Figure 3 The CPU40A shown is loaded with software (programs) to execute various processes. Examples of processors in this case include FPGAs (Field-Programmable Gate Arrays) and PLDs (Programmable Logic Devices) whose circuit structure can be changed after manufacturing, and ASICs (Application Specific Integrated Circuits), which are dedicated electronic circuits with circuit structures specifically designed for executing specific processes. Furthermore, each process can be executed by one of these various processors, or by a combination of two or more processors of the same or different types (e.g., multiple FPGAs, and a combination of a CPU and an FPGA). More specifically, the hardware construction of these various processors is an electronic circuit composed of circuit elements such as semiconductor components.

[0111] Alternatively, the programs described in this embodiment can also be provided as non-transitory computer-readable recording media such as CD-ROM (Compact Disc Read-Only Memory), DVD-ROM (Digital Versatile Disc Read Only Memory), and USB (Universal Serial Bus) storage. Alternatively, the programs can be downloaded from an external device via a network.

[0112] The above describes one embodiment of the present disclosure, but the present disclosure is not limited to the above. Various modifications can be made in addition to the above without departing from its spirit.
