The third display unit 26 is set on the upper side of the vehicle of the first display unit 24 and is constituted by a projection surface projected by a third display device 48 (see FIG. 2) which is a head-up display device. Specifically, the third display device 48 is provided on the front side of the vehicle of the instrument panel 14, and is configured such that an image is projected from the third display device 48 to the third display unit 26 of the windshield glass 18. That is, the third display unit 26 is a part of the windshield glass 18 that is the projection surface of the third display device 46.

[0033] In addition, in the present embodiment, the content displayed on the first display unit 24 will be described by the vehicle display control device 28, but it is not limited thereto, and it may be configured to be displayed on the second display unit 25 and the third display unit 26.

[0034] Here, the vehicle V is provided with a vehicle display control device 28. The vehicle display control device 28 of the present embodiment is, for example, an ECU (Electronic Control Unit) that performs various controls.

[0035] (Hardware Configuration of Vehicle Display Control System 10) As shown in FIG. 2, the vehicle display control system 10 is configured to include a vehicle display control device 28.

[0036] The vehicle display control device 28 includes a CPU (Central Processing Unit: processor) 30, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 34, a storage 36, a communication interface (communication I / F) 38, and an input / output interface (input / output I / F) 40. Each component is communicably connected to each other via an internal bus 41.

[0037] The CPU 30 is a central processing unit that executes various programs and controls each part. That is, the CPU 30 reads a program from the ROM 32 or the storage 36 and executes the program using the RAM 34 as a working area. Also, the CPU 30 performs control of each of the above configurations and various arithmetic processes according to the program recorded in the ROM 32 or the storage 36.

[0038] The ROM 32 stores various programs and various data. The RAM 34 temporarily stores a program or data as a working area. The storage 36 is composed of an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and is a non-temporary recording medium that stores various programs including an operating system and various data. In the present embodiment, a display program or the like for performing display control processing is stored in the ROM 32 or the storage 36.

[0039] The communication I / F 38 is an interface for the vehicle display control device 28 to communicate with an external server and other devices. For example, standards such as CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), and Wi-Fi (registered trademark) are used.

[0040] Connected to the input / output I / F 40 are a right operation switch 17R, a left operation switch 17L, a first display device 42, a second display device 44, a third display device 46, and sensors 50.

[0041] The first display device 42 causes an image to be displayed on the first display unit 24. The second display device 44 causes an image to be displayed on the second display unit 25. The third display device 46 causes an image to be displayed on the third display unit 26.

[0042] The sensors 50 include a GPS (global positioning system) device that receives GPS signals from a plurality of GPS satellites to determine the position of the host vehicle. Further, the sensors 50 include peripheral detection sensors such as a radar device and a camera. The radar device is a sensor for detecting objects such as pedestrians and other vehicles present around the vehicle, and the camera is a sensor that captures the surroundings of the vehicle and outputs the captured image.

[0043] Furthermore, the sensors 50 include a vehicle speed sensor that directly or indirectly detects and outputs the speed of the vehicle, an acceleration sensor that directly or indirectly detects and outputs the acceleration of the vehicle, and a steering angle sensor that directly or indirectly detects and outputs the steering angle of the vehicle.

[0044] Also, the input / output I / F 40 of the vehicle display control device 28 is electrically connected to the driving support ECU 52. The driving support ECU 52 is a control unit for performing driving support of the vehicle V without the driving operation by the occupant, and this driving support ECU 52 is electrically connected to a throttle actuator, a brake actuator, and a steering actuator.

[0045] The throttle actuator is an actuator that changes the throttle opening of the vehicle, and the brake actuator is an actuator that changes the braking force generated by the braking device of the vehicle. Also, the steering actuator is an actuator that changes the steering amount by the steering device of the vehicle.

[0046] Here, the driving support ECU 52 is configured to determine the situation of the vehicle V and its surroundings based on the information obtained from the sensors 50, and to be able to control the throttle actuator, the brake actuator, and the steering actuator according to the surrounding situation.

[0047] In this embodiment, it is configured to be able to switch between a driving support mode and a manual driving mode. In the driving support mode, as described above, the vehicle V is driven without at least some of the driving operations by the vehicle occupants. On the other hand, in the manual driving mode, the occupants perform all of the driving operations. Note that the driving support mode of this embodiment includes an automatic driving mode in which the occupants do not perform driving operations.

[0048] (Functional Configuration of Vehicle Display Control Device 28) The vehicle display control device 28 realizes various functions by using the above hardware resources. The functional configuration realized by the vehicle display control device 28 will be described with reference to FIG. 3.

[0049] As shown in FIG. 3, the vehicle display control device 28 includes, as a functional configuration, a right operation acquisition unit 62, a left operation acquisition unit 64, a display unit 66, a display item change unit 68, a display item storage unit 70, and a display item setting unit 72. Note that each functional configuration is realized by the CPU 30 reading and executing a program stored in the ROM 32 or the storage 36.

[0050] When the right operation switch 17R is operated, the right operation acquisition unit 62 acquires the content of the operation. Specifically, the right operation acquisition unit 62 acquires which of the first operation and the second operation is performed on the right operation switch 17R. In this embodiment, as an example, the first operation is an operation when the right operation switch 17R is pressed for a short time only, and the second operation is a so-called long-press operation when the right operation switch 17R is pressed for a long time equal to or longer than a predetermined time.

[0051] When the left operation switch 17L is operated, the left operation acquisition unit 64 acquires the content of the operation. Specifically, the left operation acquisition unit 64 acquires which of the first operation and the second operation is performed on the left operation switch 17L.

[0052] The display unit 66 performs display on a plurality of display areas provided adjacent to the interior of the vehicle. Specifically, the display unit 66 performs a predetermined display on the display area of the first display unit 24. FIG. 4 shows a display example displayed on the first display unit 66.

[0053] As shown in FIG. 4, three adjacent display areas 80CT, 80R, and 80L are provided in the first display unit 66. In FIG. 4, for convenience of explanation, the boundary lines of the adjacent display areas are illustrated, but actually the boundary lines are not displayed.

[0054] The display area 80CT is located at the center in the left - right direction of the first display unit 66, and information related to driving support by the driving support ECU 52 is displayed. Further, an item indicating the engine speed is displayed in a substantially arc shape at the peripheral edge of the display area 80CT. Furthermore, the speed and shift range of the current vehicle V are displayed in the display area 80CT.

[0055] Adjacent to the right side of the display area 80CT, a display area 80R is provided, and a driving route is shown in this display area 80R. Specifically, the distance to the intersection where a right or left turn is made is displayed numerically, and the route is displayed by an arrow.

[0056] Adjacent to the left side of the display area 80CT, a display area 80L is provided, and information related to audio is displayed in this display area 80L. Specifically, information such as the name of the music currently being played is displayed.

[0057] The display item change unit 68 shown in FIG. 3 changes the display items for each display area among the display items displayed in the display areas 80CT, 80R, and 80L. Also, the display item storage unit 70 stores information related to the display items set for each display area. In this embodiment, as an example, it is configured to be able to store three combinations of the display items displayed in the display areas 80CT, 80R, and 80L. The combinations of display items are stored in the storage 36 or an external server, etc.

[0058] The display item change unit 68 reads a combination of display items stored in the storage 36 or an external server or the like in response to an operation by the occupant, and displays it in the display areas 80CT, 80R, and 80L. In the present embodiment, as an example, the display item change unit 68 changes the display items when a first operation is performed on the right operation switch 17R or a first operation is performed on the left operation switch 17L by the occupant.

[0059] For example, when it is detected by the right operation acquisition unit 62 that a first operation has been performed on the right operation switch 17R, the display item change unit 68 changes the display items, thereby shifting from the state of FIG. 4 to the state of FIG. 5.

[0060] As shown in FIG. 5, map information is displayed in the display area 80CT of the first display unit 66. Specifically, in the display area 80CT, a map, the position and traveling direction of the current vehicle V are displayed. Also, in the display area 80CT, the engine speed, the speed of the vehicle V, and the shift range are displayed as in FIG. 4. That is, in the present embodiment, even when the display items in the display area 80CT are changed by the display item change unit 68, a part of the information necessary during traveling is configured to be always displayed without being changed.

[0061] Travel information is displayed in the display area 80R. Specifically, the average speed of the vehicle V is displayed above the display area 80R, and the traveling distance of the vehicle V is displayed below the display area 80R. Since the traveling distance can be reset at an arbitrary timing, the distance traveled by the vehicle V after being reset is displayed.

[0062] Information regarding fuel-efficient driving is displayed in the display area 80L. Specifically, a score for evaluating fuel-efficient driving is displayed at the upper part of the display area 80L, and evaluation values regarding fuel-efficient driving are displayed in five levels below the score.

[0063] At Start, an evaluation value regarding fuel-efficient driving until the vehicle V reaches a predetermined speed from a stopped state is displayed. At Cruise, an evaluation value regarding fuel-efficient driving while the vehicle V is traveling in a predetermined speed range is displayed. Also, at Stop, an evaluation value regarding fuel-efficient driving until the vehicle V stops from a predetermined speed is displayed.

[0064] Note that when the occupant performs a first operation on the right operation switch 17R, the display switches from that in FIG. 4 to that in FIG. 5. However, when the occupant performs a first operation on the left operation switch 17L in the state of FIG. 4, another display item is displayed on the first display unit 66 by the display item changing unit 68.

[0065] Also, when the occupant performs a first operation on the right operation switch 17R from the state of FIG. 5, another display item is displayed on the first display unit 66 by the display item changing unit 68. Here, in this embodiment, three combinations of display items are stored. Each time the occupant performs a first operation on the right operation switch 17R, the three stored display items are displayed in order. For this reason, when the occupant performs a first operation on the right operation switch 17R three times from the state of FIG. 4, the display item on the first display unit 66 returns to the state of FIG. 4. Also, each time the occupant performs a first operation on the left operation switch 17L, the three stored display items are displayed in reverse order. In this way, the display item changing unit 68 causes the display item determined by the operation of the occupant from among a plurality of display item candidates to be displayed in the display areas 80CT, 80R, and 80L of the first display unit 66.

[0066] The display item setting unit 72 shown in FIG. 3 sets display items for each display area of the first display unit 66. Also, in this embodiment, a setting image by the display item setting unit 72 is displayed in the display area based on a second operation different from the first operation by the right operation switch 17R or the left operation switch 17L.

[0067] Specifically, when the occupant performs a second operation on the right operation switch 17R or the left operation switch 17L from the state shown in FIG. 5, the right operation acquisition unit 62 detects that the second operation has been performed on the right operation switch 17R. And in this case, the display item setting unit 72 causes the display area selected by the occupant to shift to the setting mode.

[0068] In the setting mode, the occupant can determine the display item from among the preset candidates. Specifically, in the setting mode of the display area 80CT, every time the occupant operates the right operation switch 17R or the left operation switch 17L, the candidates for the display item are switched. And when the candidate to be displayed is displayed in the display area 80CT, the display item of the display area 80CT is determined by the occupant performing a predetermined operation.

[0069] Also, the display item setting unit 72 displays the setting image 82 shown in FIG. 6 in the setting mode. In this setting image 82, it is shown whether the candidates for the display item in the display area 80R are in the displayed state or the non-displayed state. In FIG. 6, as an example, the candidates related to audio are in the non-displayed state. Therefore, when changing the display item of the display area 80R, the audio candidates are skipped without being displayed.

[0070] (Function) Next, the function of this embodiment will be described.

[0071] (Display control process) An example of the display control process by the vehicle display control device 28 will be described using the flowchart shown in FIG. 7. This display process is executed by the CPU 30 reading the display program from the ROM 32 or the storage 36, expanding it in the RAM 34, and then executing it.

[0072] The CPU 30 starts the display for the first display unit 66 in step S102. Specifically, when the vehicle V is started, the CPU 30 starts the display for the first display unit 66 in step S102. Here, the CPU 30 displays preset display items for the display areas 80CT, 80R, and 80L of the first display unit 66 by the function of the display unit 66. For example, the display unit 66 may display the display items that were displayed during the previous driving.

[0073] The CPU 30 determines whether the first operation has been performed in step S104. Specifically, when the right operation acquisition unit 62 detects that the first operation of the right operation switch 17R has been performed, the CPU 30 determines that the first operation has been performed. Also, when the left operation acquisition unit 64 detects that the first operation of the left operation switch 17L has been performed, the CPU 30 determines that the first operation has been performed. Therefore, when the first operation is performed on at least one of the right operation switch 17R and the left operation switch 17L in step S104, the CPU 30 determines that the first operation has been performed and proceeds to the process of step S106.

[0074] The CPU 30 changes the display items in step S106. Specifically, the CPU 30 displays the combination of the display items stored in the display item storage unit 70 on the first display unit 66 by the function of the display item change unit 68. Then, the CPU 30 ends the display control process.

[0075] On the other hand, when the CPU 30 determines in step S104 that the first operation has not been performed, it proceeds to the process of step S108 and determines whether the second operation has been performed. Specifically, when the right operation acquisition unit 62 detects that the second operation of the right operation switch 17R has been performed, the CPU 30 determines that the second operation has been performed. Also, when the left operation acquisition unit 64 detects that the second operation of the left operation switch 17L has been performed, the CPU 30 determines that the second operation has been performed. Therefore, when the second operation is performed on at least one of the right operation switch 17R and the left operation switch 17L in step S104, the CPU 30 determines that the second operation has been performed and proceeds to the process of step S110.

[0076] The CPU 30 shifts to the setting mode in step S110. Specifically, the CPU 30 shifts to a setting mode in which the display items of the display area 80CT, the display area 80R, and the display area 80L can be individually set by the function of the display item setting unit 72. For example, the CPU 30 displays the setting image 82 shown in FIG. 6 by the function of the display item setting unit 72. Then, the CPU 30 ends the display control process. Also, when the CPU 30 determines in step S108 that the second operation has not been performed, the CPU 30 also ends the display control process.

[0077] As described above, in the vehicle display control system 10 and the vehicle display control device 28 according to the present embodiment, the display item changing unit 68 changes the display items for each display area with respect to the display items displayed in a plurality of display areas by the display unit 66. Thereby, the occupant can set the display items to be displayed for each display area.

[0078] Also, in the present embodiment, since the information regarding the display items set for each display area is stored by the display item storage unit 70, it is not necessary to change the display content every time of driving.

[0079] Furthermore, in the present embodiment, candidates for display items are set in advance, and the content to be displayed in the display area can be changed only by selecting the display items desired by the occupant from among the candidates.

[0080] Furthermore, in the present embodiment, by setting unnecessary display items to be non-displayed by the function of the display item setting unit 72, the display items can be excluded from the candidates, so that the annoyance when the occupant selects a display item from the candidates can be reduced.

[0081] Also, in the present embodiment, when the occupant performs a first operation on the right operation switch 17R or the left operation switch 17L, the display item is changed, and when the occupant performs a second operation on the right operation switch 17R or the left operation switch 17L, the setting image is displayed in the display area. Thereby, without providing other operation switches or the like, the occupant can utilize the functions of both the display item changing unit 68 and the display item setting unit 72.

[0082] In particular, in the present embodiment, since the right operation switch 17R and the left operation switch 17L are provided on the steering wheel 16, the occupant can easily change the display item even when the line of sight is directed forward.

[0083] As described above, the vehicle display control system 10 and the vehicle display control device 28 according to the embodiment have been described. However, it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention. For example, in the above embodiment, the configuration in which the right operation switch 17R and the left operation switch 17L are provided on the steering wheel 16 has been described. However, the present invention is not limited to this, and a configuration in which an operation switch is provided at another location may also be used.

[0084] In the above embodiment, the right operation switch 17R and the left operation switch 17L are switches that can be pressed. However, the present invention is not limited to this. For example, a touch-type operation switch using an electrostatic sensor or the like may be used.

[0085] Furthermore, in the above-described embodiment, as shown in FIG. 4, three display areas 80CT, 80R, and 80L are provided, but the present invention is not limited thereto. For example, it may be applied to a configuration including four or more display areas. Also, the configuration in which the display areas are adjacent to each other in the vehicle width direction is not limited, and a configuration in which the display areas are adjacent to each other in the vehicle vertical direction may be adopted.

[0086] Furthermore, the display items described in the above embodiment are merely examples and are not limited to these display items. For example, display items other than the display items described in the above embodiment may be displayed on the first display unit 24.
