[0024] The display operation unit 36 ​​is an operation unit that allows the driver to operate the display 38. As shown in Fig. 2, the display operation unit 36 ​​is provided on the first handle portion 281. The display operation unit 36 ​​includes a first operation unit 40 and a second operation unit 42.

[0025] The first operation unit 40 is an operation unit for selecting a plurality of icons 78 displayed on the display 38. A more detailed description of the display 38 and the plurality of icons 78 will be provided later. The first operation unit 40 accepts directional input along the up / down direction DUD. The first operation unit 40 is provided with, for example, two switches 44 that accept up / down directional input. The two switches 44 include a first switch 441 that accepts up directional input and a second switch 442 that accepts down directional input. The first switch 441 and the second switch 442 are arranged side by side along the up / down direction DUD. It is preferable that the first switch 441 be located in the up direction DU relative to the second switch 442.

[0026] The second operation unit 42 is an operation unit for accepting an operation for the content 82 displayed on the display 38 in response to the selection of the icon 78. A more detailed description of the content 82 will be provided later. The second operation unit 42 accepts directional inputs along multiple directions and a confirmation operation for the content 82. For example, a multi-function switch or the like may be used as the second operation unit 42. The multi-function switch may be, for example, a multi-function joystick. The multi-function switch can accept not only directional inputs in the up / down directions DUD and the left / right directions DLR, but also directional inputs in directions intersecting both the up / down directions DUD and the left / right directions DLR (diagonal directions). As shown in FIG. 2 , the multi-function switch may be marked with an arrow indicating a left direction DL, an arrow indicating a right direction DR, an arrow indicating an up direction DU, and an arrow indicating a down direction DD. The multi-function switch may also be marked with a diagonal arrow. The confirmation operation using the multi-function switch can be performed by pressing a confirmation button provided in the center of the multi-function switch, but is not limited to this. For example, the confirmation operation may be performed by pressing the entire multi-function switch toward the first handle portion 281 (vehicle body).

[0027] The first operating unit 40 and the second operating unit 42 are arranged side by side in the left-right direction DLR. More specifically, the second operating unit 42 is located to the right in the right direction DR relative to the first operating unit 40.

[0028] 2 shows an upper end 40t1 and a lower end 40t2 of the first operating unit 40. The upper end 40t1 is the end of the first operating unit 40 in the upward direction DU. The upper end 40t1 may be included in the first switch 441 described above. The lower end 40t2 is the end of the first operating unit 40 in the downward direction DD. The lower end 40t2 may be included in the second switch 442 described above.

[0029] The center position of the second operating unit 42 in the up-down direction DUD is preferably between the position of the upper end 40t1 of the first operating unit 40 in the up-down direction DUD and the position of the lower end 40t2 of the first operating unit 40 in the up-down direction DUD. In other words, the center position of the second operating unit 42 in the up-down direction DUD is preferably between the position of the first switch 441 in the up-down direction DUD and the position of the second switch 442 in the up-down direction DUD.

[0030] In this case, it is preferable that the first switch 441 and the second switch 442 are disposed separately along the up-down direction DUD. As shown in FIG. 2 , the position of at least a portion 40a of the first operating unit 40 in the up-down direction DUD may overlap the position of the second operating unit 42 in the up-down direction DUD. In this case, it is preferable that the height of the portion 40a is shorter than the height of the second operating unit 42. The heights of the portion 40a and the second operating unit 42 each represent the amount of protrusion in the push-in direction of the switch 44. The overall height of the first operating unit 40 may be shorter than the height of the second operating unit 42.

[0031] The display 38 is, for example, a liquid crystal display, but is not limited to this. The display 38 is disposed between the pair of handle portions 28 in the left-right direction DLR. By disposing the display 38 in this manner, the driver seated in the seat 12 ( FIG. 1 ) of the vehicle 10 can view the display 38 while facing straight ahead (forward direction DF).

[0032] The display 38 is a horizontally long display 38. That is, the dimension D38L of the display 38 in the left-right direction DLR when viewed from the front is longer than the dimension D38S of the display 38 in the up-down direction DUD when viewed from the front (D38L > D38S). In other words, the left-right direction DLR matches the longitudinal direction of the display 38 when viewed from the front. Also, the up-down direction DUD matches the lateral direction of the display 38 when viewed from the front.

[0033] The display 38 has a plurality of display areas 46 (461 to 464). That is, as shown in FIG. 2 by the two-dot chain lines, the display 38 has a first display area 461, a second display area 462, a third display area 463, and a fourth display area 464. The plurality of display areas 46 can be virtually partitioned on the single display 38.

[0034] The first display area 461 and the second display area 462 are arranged side by side along the longitudinal direction of the display 38. The direction from the first display area 461 to the second display area 462 along the longitudinal direction of the display 38 coincides with the direction from the first operation unit 40 to the second operation unit 42 along the longitudinal direction. Therefore, for example, if the direction from the first operation unit 40 to the second operation unit 42 is the right direction DR, the direction from the first display area 461 to the second display area 462 is also the right direction DR ( FIG. 2 ).

[0035] The longitudinal direction of the first display area 461 coincides with the widthwise direction of the display 38. On the other hand, the longitudinal direction of the second display area 462 coincides with the lengthwise direction of the display 38.

[0036] The third display area 463 is located on one side of the display 38 in the widthwise direction of the display 38. For example, the third display area 463 is located in a relatively upper part of the display 38 ( FIG. 2 ), but may also be located in a lower part of the display 38.

[0037] The fourth display area 464 may be arranged in the remaining portion of the display 38 excluding the first display area 461, the second display area 462, and the third display area 463. The fourth display area 464 may be arranged, for example, alongside the third display area 463 along the longitudinal direction of the display 38 ( FIG. 2 ), but is not limited to this.

[0038] The first display area 461 is preferably located at an end 38t (left end) of the display 38 in the direction from the second display area 462 to the first display area 461 along the longitudinal direction of the display 38.

[0039] Furthermore, it is preferable that the area of ​​the second display area 462 is the largest among the areas of the first display area 461, the second display area 462, the third display area 463, and the fourth display area 464.

[0040] Furthermore, it is preferable that each of the second display area 462 and the third display area 463 includes a central portion (longitudinal center) of the display 38 in the longitudinal direction of the display 38. The longitudinal center includes a portion of the display 38 through which a center line LC (dash-dotted line in FIG. 2 ) of the display 38 passes. The center line LC is an imaginary straight line that runs along the width direction of the display 38 and passes through the center of the display 38 in the longitudinal direction. The center line LC of the display 38 coincides with, for example, a center line (not shown) that runs along the up-down direction DUD in the left-right direction DLR of the vehicle 10, but is not limited to this.

[0041] The above-described plurality of display areas 46 can be used to display various types of display information. A more detailed description of the display information that can be displayed in each of the plurality of display areas 46 will be given later.

[0042] 3 is a block diagram of the vehicle 10. A block diagram of a display system 48 provided in the vehicle 10 is shown in FIG.

[0043] 3 , the vehicle 10 further includes a display system 48. The display system 48 controls the display 38. The display system 48 includes a meter display control unit 50 and a display control device 52.

The meter display control unit 50 may be included in the PCU (ECU) described above. The meter information includes, for example, speed information indicating the speed of the vehicle 10 and mileage information indicating the mileage of the vehicle 10, but is not limited to these. The meter information may also include information indicating the state of the vehicle 10 (e.g., the driving mode) that can be acquired by the indicator 543 of the vehicle 10.

[0045] 3, the meter display control unit 50 is connected to various devices 54, such as a wheel speed sensor (vehicle speed sensor) 541, an odometer 542, and an indicator 543. This allows the meter display control unit 50 to acquire various output signals output from the multiple devices 54. The meter display control unit 50 displays meter information on the display 38 based on the acquired various output signals. The devices 54, such as the vehicle speed sensor 541, the odometer 542, and the indicator 543, are provided in the vehicle 10 as appropriate.

[0046] The meter display control unit 50 displays meter information (speed information, mileage information, etc.) in a third display area 463 of the display 38. In this case, it is preferable that the speed information among the meter information be displayed in the longitudinal center of the third display area 463 (see also FIG. 5 ).

[0047] FIG. 4 is a block diagram of the display control device 52 provided in the vehicle 10.

[0048] The display control device 52 includes an electronic device (computer) for controlling the display 38 for, for example, in-vehicle infotainment (IVI).

Point-to-point communication may be performed between the communication module and the user terminal 62. Point-to-point communication may include short-range wireless communication. In this case, short-range wireless communication is, for example, Bluetooth (registered trademark), but is not limited to this.

[0050] The calculation unit 58 includes a predetermined processing circuit (not shown). The processing circuit includes one or more processors, such as a central processing unit (CPU) or a graphics processing unit (GPU). The processing circuit may include a predetermined integrated circuit, such as an application specific integrated circuit (ASIC) or a field-programmable gate array (FPGA).

[0051] The storage unit 60 includes one or more memories. The one or more memories include non-volatile memories. Non-volatile memories are recording media that non-temporarily store programs, tables, map information, etc. For example, non-volatile memories include ROM (Read Only Memory), flash memory, etc. The storage unit 60 (one or more memories) may include volatile memories. For example, volatile memories include RAM (Random Access Memory).

[0052] The calculation unit 58 includes an information acquisition unit 64, a display information generation unit 66, a display control unit 68, an operation recognition unit 70, a transition determination unit 72, and a condition determination unit 74. The information acquisition unit 64, the display information generation unit 66, the display control unit 68, the operation recognition unit 70, the transition determination unit 72, and the condition determination unit 74 are realized by the calculation unit 58 (processor) executing a program stored in the storage unit 60 (memory). At least some of the information acquisition unit 64, the display information generation unit 66, the display control unit 68, the operation recognition unit 70, the transition determination unit 72, and the condition determination unit 74 may be realized by an integrated circuit such as the ASIC or FPGA described above.

[0053] The information acquisition unit 64 acquires various types of information required for the display information generation unit 66, which will be described later. The information acquired by the information acquisition unit 64 includes, for example, location information, battery information, and time information. The location information is information indicating the location (coordinates) of the vehicle 10. The information acquisition unit 64 acquires the location information based on, for example, an output signal of a location sensor 544, such as a GNSS (Global Navigation Satellite System) sensor, provided on the vehicle 10. The location sensor 544 may be included in the device 54. The battery information is information indicating the remaining battery capacity. The remaining battery capacity is the remaining amount of power stored in the battery unit 26. The time information is information indicating the time.

[0054] The information acquisition unit 64 may acquire the above-described speed information. In this case, the information acquisition unit 64 may acquire the speed information acquired by the meter display control unit 50 from the meter display control unit 50, but it is preferable that the information acquisition unit 64 acquires the output signal of the vehicle speed sensor 541 separately from the meter display control unit 50 (FIG. 3).

[0055] Furthermore, the information acquisition unit 64 may acquire information from the user terminal 62 via the communication unit 56.

[0056] The display information generation unit 66 generates display information that is information to be displayed on the display 38. The display information includes information to be displayed in the first display area 461, information to be displayed in the second display area 462, and information to be displayed in the fourth display area 464.

[0057] FIG. 5 is a diagram illustrating the display 38.

[0058] The information displayed in the first display area 461 includes the content menu screen 76. In other words, the display information generating unit 66 generates information for displaying the content menu screen 76 in the first display area 461.

[0059] The content menu screen 76 is a screen on which a plurality of icons 78 corresponding to a plurality of pieces of content (IVI content) 82 are listed. The display information generation unit 66 generates display information such that the plurality of icons 78 are listed along the short side of the display 38. The plurality of pieces of content 82 may include various applications, such as a map display application (navigation application), a call application, and a music playback application. The applications may be stored in advance in the storage unit 60 (memory) and executed by the calculation unit 58 (processor).

[0060] As shown in FIG. 5 , the information displayed in the first display area 461 may include guidance information (predetermined guidance information) 80. The guidance information 80 is information for instructing the driver how to operate the content menu screen 76. The guidance information 80 includes, for example, a graphic 801 pointing to one side of the width of the display 38 and a graphic 802 pointing to the other side of the width. The graphic 801, for example, points to the upward direction DU, thereby instructing the driver that an upward direction input can be accepted for the content menu screen 76. In contrast, the graphic 802, for example, points to the downward direction DD, thereby instructing the driver that a downward direction input can be accepted for the content menu screen 76. Each of the graphic 801 and the graphic 802 includes, for example, a triangular figure (symbol), but is not limited to this. For example, at least one of the graphic 801 and the graphic 802 may include an arrow-shaped symbol.

[0061] The information displayed in the second display area 462 includes content (content screen) 82 corresponding to the icon 78 selected by the driver from among the plurality of icons 78. In other words, the display information generating unit 66 generates information for displaying the content 82 corresponding to the selected icon 78 in the second display area 462.

[0062] 5, the plurality of icons 78 may include an icon 78 (icon 78A) for transitioning to a home screen 82A. The home screen 82A is, for example, content 82 that is first displayed after the display 38 is turned on. The plurality of icons 78 may also include an icon 78 (icon 78B) for transitioning to a settings screen. Although not shown in the figure, the settings screen is content 82 that is common to each content 82 or that is used to change general settings of the display 38.

[0063] The display information generation unit 66 may generate information for displaying the home screen 82A and the setting screen in the second display area 462. In this case, the display information generation unit 66 may cause information indicating the driving mode of the vehicle 10, information indicating the distance traveled (Current Trip) of the vehicle 10, information indicating the remaining driving range (Rang) of the vehicle 10, etc. to be displayed on the home screen 82A. That is, the home screen 82A may have an area DM in which the driving mode is displayed, an area CT in which the distance traveled is displayed, an area RG in which the remaining driving range is displayed, and an area NTF in which notifications to the user are displayed.

[0064] The driving range of the vehicle 10 may be predicted based on, for example, map information (planned driving route and gradient), distance already traveled, remaining battery charge, etc. The information that may be displayed on the home screen 82A is not limited to that illustrated in Fig. 5. At least one piece of information among the plurality of pieces of information that may be displayed on the home screen 82A may be displayed in a display area 46 other than the second display area 462 when content 82 (icon 78) other than the home screen 82A is selected (see also Fig. 6).

[0065] The information displayed in the fourth display area 464 includes, for example, the current time and the remaining battery power. In this case, the fourth display area 464 has an area TM where the current time is displayed and an area SOC where the remaining battery power is displayed. The display information generating unit 66 generates information for displaying the current time and the remaining battery power in the fourth display area 464 based on the time information and battery information acquired by the information acquiring unit 64.

[0066] The display control unit 68 causes the display information generated by the display information generation unit 66 to be displayed on the display 38. That is, the display control unit 68 causes a content menu screen 76 (plurality of icons 78) to be displayed in the first display area 461. The display control unit 68 also causes content 82 corresponding to the selected icon 78 to be displayed in the second display area 462. Furthermore, the display control unit 68 causes the fourth display area 464 to display the remaining battery power and the current time.

[0067] The plurality of icons 78 displayed in the first display area 461 are displayed so as to be aligned along the short side direction of the display 38. In this case, the display control unit 68 may use a program launcher or the like to display the plurality of icons 78 in the first display area 461 regardless of the selection state of the icons 78. The display control unit 68 also displays the above-mentioned guidance information 80 in the first display area 461. The display control unit 68 may display the guidance information 80 by superimposing it on a part of the content menu screen 76.

[0068] The operation recognition unit 70 recognizes the driver's operation performed using the display operation unit 36. For example, in response to an operation of the display operation unit 36, an electrical signal is input to the display control device 52. The operation recognition unit 70 recognizes the driver's operation based on the electrical signal. This allows the operation recognition unit 70 to recognize an operation of the driver selecting an icon 78 via the first operation unit 40 (icon selection operation, selection operation) and an operation performed by the driver on content 82 via the second operation unit 42 (content operation). The operations that can be accepted by the operation recognition unit 70 as content operations are predetermined depending on the content 82.

[0069] 6 is a diagram illustrating an example of the display 38. The content 82 (call list 82C) shown in FIG. 6 is different from the content 82 (home screen 82A) shown in FIG.

[0070] For example, content 82 corresponding to a calling application (icon 78C) may include a call list 82C, which is a list for selecting a call partner CA (CA1 to CA3). In this case, operations that can be performed on content 82 may include selecting a call partner CA using call list 82C, making a call to the selected call partner CA, answering an incoming call, disconnecting the call, etc. Furthermore, for example, operations that can be performed on content 82 corresponding to a music playback application (icon 78D) may include selecting a song, playing or stopping (pausing) the selected song, etc.

[0071] When the operation recognition unit 70 recognizes an icon selection operation, the above-described display control unit 68 changes the content 82 displayed in the second display area 462 in accordance with the selection state of the icon 78. In other words, the display control unit 68 executes a screen transition in accordance with the icon selection operation.

[0072] With regard to this screen transition, the transition determination unit 72 determines whether or not a content 82 (second display information) other than the predetermined content 82 is selected while the predetermined content 82 (first display information) is being displayed on the display 38. In other words, the transition determination unit 72 determines whether or not the driver has instructed a transition from a predetermined first state to a second state different from the first state. The first state is a state in which the predetermined content 82 is displayed on the display 38. In contrast, the second state is a state in which a content 82 other than the predetermined content 82 is displayed on the display 38.

[0073] Fig. 7 is a diagram illustrating an example of the display 38. Fig. 7 shows a navigation screen 82E, which is content 82 corresponding to a map display application (icon 78E).

[0074] The predetermined content 82 is, for example, a navigation screen 82E displayed by a map display application (icon 78E). The navigation screen 82E displays, for example, map information MAP, a vehicle symbol SYM, and turn-by-turn information 84. The map information MAP indicates a map of the area around the vehicle 10. The vehicle symbol SYM indicates the position of the vehicle 10 on the map. The turn-by-turn information 84 indicates an arrow for guiding the vehicle 10 to the destination. The transition determination unit 72 determines whether or not the driver has selected an icon 78 other than the map display application (icon 78E) while the navigation screen 82E is displayed in the second display area 462.

[0075] When the transition determination unit 72 determines that a transition (screen transition) from the first state to the second state has been instructed, the display control unit 68 described above executes a parallel display, which will be described next.

[0076] 8 is a diagram illustrating the display 38. The display 38 is shown in FIG. 8 when a parallel display is performed.

[0077] The side-by-side display refers to displaying the first display information displayed in the first state and the second display information displayed in the second state in the second display area 462. In this case, the display control unit 68 preferably displays the first display information and the second display information side by side along the longitudinal direction of the display 38. Explaining based on the above example, by executing the side-by-side display, the display control unit 68 displays two pieces of content 82 including the navigation screen 82E, which is the predetermined content 82, side by side along the longitudinal direction of the display 38.

[0078] When an operation is performed using the second operation unit 42 while parallel display is being executed, the operation recognition unit 70 recognizes that a content operation has been performed on the second display information. Note that when a predetermined operation is performed and an operation is performed using the second operation unit 42 while parallel display is being executed, the operation recognition unit 70 may recognize that a content operation has been performed on the first display information.

[0079] When parallel display is performed, the direction from the first display information to the second display information preferably coincides with the direction from the display 38 to the display operation unit 36 ​​(second operation unit 42) along the longitudinal direction of the display 38. Referring to the example described above, when parallel display is performed, the direction from the navigation screen 82E to the content 82 other than the navigation screen 82E preferably coincides with the leftward direction DL. In this case, the direction from the navigation screen 82E to the content 82 other than the navigation screen 82E also coincides with the direction from the accelerator operation unit 34 to the display 38 (see also FIG. 2 ).

[0080] As shown in Figures 7 and 8, the navigation screen 82E may include turn-by-turn information (arrow symbols) 84. Referring to the example described above, the first display information displayed in parallel may include the above-described turn-by-turn information 84. In this case, as shown in Figure 8, the display control unit 68 preferably displays the turn-by-turn information 84 in the portion of the region 462A in which the first display information (navigation screen 82E) is displayed, which is closer to the center line LC (described above) in the longitudinal direction. More specifically, in this case, the display control unit 68 preferably displays the turn-by-turn information 84 in the portion of the region 462A, which is part of the second display region 462, closer to the center line LC (described above).

[0081] The condition determination unit 74 determines whether a predetermined condition, which is a predetermined condition, is satisfied. The predetermined condition is, for example, that the speed of the vehicle 10 is equal to or greater than a predetermined speed threshold. In this case, the condition determination unit 74 can determine whether the predetermined condition is satisfied based on the speed information acquired by the information acquisition unit 64.

[0082] When the above-described parallel display is performed, the display control unit 68 may restrict content operations performed using the second operation unit 42, based on the result of the determination by the condition determination unit 74. In other words, when parallel display is performed, the display control unit 68 may not reflect at least a part of the operations recognized by the operation recognition unit 70 in the display information, based on the result of the determination by the condition determination unit 74.

[0083] For example, the call list 82C described above may be displayed in parallel with the first display information as the second display information. When the speed of the vehicle 10 is equal to or greater than a speed threshold, the display control unit 68 may restrict operations on the call list 82C. The display control unit 68, for example, restricts scrolling operations on the call list 82C. Referring to FIG. 8 , even if four or more call counterparties CAs are registered in the call list 82C, the number of call counterparties CAs selectable by the driver is limited to a predetermined number (three) that can be displayed at one time in a portion (area 462B) of the second display area 462. When the predetermined condition described above is not met, call counterparties CAs other than the three can be selected by the driver scrolling the call list 82C via the second operation unit 42.

[0084] FIG. 9 is a flowchart showing a display control method according to an embodiment.

[0085] The display control device 52 (computer) described above can execute the display control method of Fig. 9. The display control method of Fig. 9 is executed, for example, by a processor (calculation unit 58) executing a program stored in a memory (storage unit 60). As shown in Fig. 9, the display control method includes an information acquisition step S1, a display information generation step S2, and a display step S3.

[0086] In the information acquisition step S1, the information acquisition unit 64 acquires various pieces of information necessary for the display information generation unit 66. The information acquired by the information acquisition unit 64 includes, for example, location information, battery information, time information, and speed information, but is not limited to these.

[0087] In the display information generating step S2, the display information generating unit 66 generates display information to be displayed on the display 38. The display information includes information to be displayed in the first display area 461 and information to be displayed in the second display area 462. The information to be displayed in the first display area 461 includes a plurality of icons 78 (content menu screen 76), guidance information 80, etc. The information to be displayed in the second display area 462 includes content (content screen) 82 corresponding to any of the plurality of icons 78. The display information generating unit 66 may generate the display information based on information acquired by the information acquiring unit 64. For example, the display information generating unit 66 may generate information to be displayed in the fourth display area 464.

[0088] In a display step S3, the display control unit 68 controls the display 38 based on the display information generated in the display information generating step S2. As a result, a plurality of icons 78, guidance information 80, etc. are displayed in the first display area 461. In addition, content 82 corresponding to any one of the plurality of icons 78 is displayed in the second display area 462.

[0089] The display control method further includes an operation recognition step S4, a screen transition determination step S5, a screen control step S6, and a parallel display step S7.

[0090] In the operation recognition step S4, the operation recognition unit 70 recognizes an operation performed by the driver via the display operation unit 36.

[0091] In the screen transition determination step S5, the transition determination unit 72 determines whether or not the second display information has been selected while the first display information is displayed on the display 38. Based on the result of the recognition in the operation recognition step S4, the transition determination unit 72 determines whether or not the second display information has been selected while the first display information is displayed on the display 38. The first display information is, for example, a navigation screen 82E. In this case, the second display information is content 82 other than the navigation screen 82E.

[0092] If it is determined in the screen transition determination step S5 that the second display information has not been selected while the first display information is displayed on the display 38, the screen control step S6 is started. On the other hand, if it is determined in the screen transition determination step S5 that the second display information has been selected while the first display information is displayed on the display 38, the parallel display step S7 is started.

[0093] In screen control step S6, the display control unit 68 controls the display 38 based on the result of the recognition in operation recognition step S4. For example, the display control unit 68 executes screen transitions between multiple pieces of display information other than the first display information in screen control step S6. In addition, for example, the display control unit 68 controls the display 38 in accordance with a content operation, which is an operation on the content 82 displayed in the second display area 462.

[0094] Although not shown in the drawings, if the result of recognition in operation recognition step S4 is a content operation, a determination is made by the condition determination unit 74 as appropriate in screen control step S6. The condition determination unit 74 determines whether a predetermined condition is met. An example of the predetermined condition is that the speed of the vehicle 10 is equal to or greater than a speed threshold. If the condition determination unit 74 determines that the predetermined condition is met, the display control unit 68 restricts the content operation. For example, if the speed of the vehicle 10 is equal to or greater than the speed threshold, the display control unit 68 restricts the scrolling operation of the call list 82C displayed in the second display area 462.

[0095] In the parallel display step S7, the display control unit 68 controls the display 38 to execute processing for executing parallel display. That is, in the parallel display step S7, the display control unit 68 displays the first display information and the second display information described above side by side in the second display area 462. The display control unit 68 aligns the first display information and the second display information along the longitudinal direction of the landscape-oriented display 38.

[0096] According to this embodiment, the vehicle 10 and the display control device 52 can achieve the effects described below, for example.

[0097] The display control device 52 displays the plurality of icons 78 and the content 82 corresponding to one selected icon 78 of the plurality of icons 78, arranged along the longitudinal direction of the display 38. Moreover, the display control device 52 displays the plurality of icons 78 arranged along the lateral direction of the display 38. This display layout makes it possible to display sufficient information.

[0098] The direction from the first display area 461 to the second display area 462 along the longitudinal direction of the display 38 corresponds to the rightward direction DR. Furthermore, the direction from the first operation unit 40 to the second operation unit 42 along the longitudinal direction of the display 38 also corresponds to the rightward direction DR. Therefore, according to the present embodiment, the direction from the first display area 461 to the second display area 462 along the longitudinal direction of the display 38 corresponds to the direction from the first operation unit 40 to the second operation unit 42 along the longitudinal direction. This provides the driver with an intuitive sense of operation. That is, the vehicle 10 allows the driver to intuitively recognize that the first operation unit 40, which is disposed on the left side of the display operation unit 36, is an operation unit for operating the plurality of icons 78 displayed on the left side of the display 38. Furthermore, the vehicle 10 allows the driver to intuitively recognize that the second operation unit 42, which is disposed on the right side of the display operation unit 36, is an operation unit for operating the content 82 displayed on the right side of the display 38.

[0099] The first operation unit 40 has two switches 44 aligned along the short side of the display 38. That is, the alignment direction of the two switches 44 matches the alignment direction of the above-described plurality of icons 78. This allows the first operation unit 40 to provide the driver with a more intuitive operational feel.

[0100] The center position of the second operation unit 42 in the short-side direction of the display 38 is between the two switches 44. This allows the driver of the vehicle 10 to intuitively recognize that both of the two switches 44 and the second operation unit 42 are aligned along the long-side direction of the display 38.

[0101] In this case, the position of at least a portion 40a of the first operating unit 40 (two switches 44) in the short-side direction of the display 38 may overlap the position of the second operating unit 42 in the short-side direction of the display 38. The height of the portion 40a is preferably shorter than the height of the second operating unit 42. The two switches 44 may be separated along the short-side direction of the display 38. In this way, the driver is less likely to be hindered by the first operating unit 40 from moving the fingers of one hand to the second operating unit 42 while holding the first handle portion 281 in the palm of the other hand.

[0102] The handle portion 28 (first handle portion 281) on which the display operation portion 36 is provided is different from the handle portion 28 (second handle portion 282) on which the accelerator operation portion 34 is provided, so that the driver can operate the display operation portion 36 with one hand while operating the accelerator operation portion 34 with the other hand.

[0103] The direction from the first handle portion 281 to the second handle portion 282 along the longitudinal direction of the display 38 coincides with the direction from the first operating unit 40 to the second operating unit 42. In this case, it is easy to operate both the first operating unit 40 and the second operating unit 42 with the thumb.

[0104] The first display area 461 is preferably located at an end 38t of the display 38 in the longitudinal direction of the display 38. This allows sufficient display space to be secured for the content 82.

[0105] It is preferable that the display control device 52 displays a plurality of icons 78 in the first display area 461 regardless of the selection state of the icon 78. This allows the driver to intuitively recognize that, no matter which content 82 the driver is using, another content 82 other than the content 82 in question is available for selection.

[0106] The display control device 52 may display guidance information 80 for instructing the user on the icon selection operation in the first display area 461. This provides convenience to users who are unfamiliar with the icon selection operation.

[0107] According to this embodiment, the vehicle 10 and the display control device 52 can also achieve the effects described below, for example.

[0108] When second display information is selected by an icon selection operation (selection operation) while predetermined first display information is being displayed on the display 38, the display control unit 68 executes a parallel display in which at least a portion of the first display information and the second display information are displayed on the display 38. This allows a portion of the predetermined first display information to continue to be displayed. As a result, after specific display information (first display information) is displayed on the display 38, the display control device 52 can allow the driver to continue to recognize the specific display information. Furthermore, the first display information and the second display information are aligned along the longitudinal direction of the display 38. Therefore, the driver can easily distinguish between the first display information and the second display information.

[0109] The first display information includes, for example, a navigation screen 82E corresponding to a map display application (icon 78E). The navigation screen 82E includes, for example, map information MAP, turn-by-turn information 84, etc. According to the present embodiment, even if the driver selects an icon 78 other than the map display application (icon 78E), at least a part of the map information MAP, the turn-by-turn information 84, etc. can be continuously displayed on the display 38. In this way, the display control device 52 can provide the driver with the content 82 desired by the driver while reducing the risk of the driver making a mistake in the driving route.

[0110] Speed ​​information indicating the speed of the vehicle 10 may be further displayed in the longitudinal center of the display 38. That is, the area of ​​the display 38 where the speed information is displayed is preferably located in the longitudinal center of the display 38. Speed ​​information is one of the important pieces of information that attracts a relatively large amount of attention from the driver who is driving the vehicle 10. By displaying such speed information in the longitudinal center of the display 38, it is possible to suppress eye movement of the driver who is facing forward DF and attempts to visually confirm the speed information.

[0111] The speed information is displayed on the display 38 by the meter display control unit 50. The display control device 52 and the meter display control unit 50 are preferably separate devices. This allows the meter display control unit 50 to display the speed information on the display 38 even if the display control device 52 is stopped, for example.

[0112] As described above, the navigation screen 82E may include the turn-by-turn information 84. When the navigation screen 82E and content 82 other than the navigation screen 82E are displayed side by side, it is preferable that the turn-by-turn information 84 be displayed in the aforementioned central portion in the longitudinal direction of the area 462A in which the navigation screen 82E is displayed. Like speed information, the turn-by-turn information 84 is one piece of information that is of relatively great interest to the driver driving the vehicle 10. By displaying the turn-by-turn information 84 in the aforementioned central portion in the longitudinal direction, it is possible to suppress eye movement of the driver who is facing forward DF and attempts to visually confirm the turn-by-turn information 84.

[0113] The operation recognition unit 70 recognizes that a content operation performed when parallel display is executed is an operation on the second display information. As a result, when parallel display is executed, a content operation on the content 82 selected by the driver is permitted, while the display state of the first display information can be maintained regardless of the content operation.

[0114] When the side-by-side display is performed, it is preferable that the direction from the display position of the first display information to the display position of the second display information coincides with the direction from the display 38 to the second operation unit 42 along the longitudinal direction of the display 38. This can provide the driver with an intuitive sense of operation. For example, the second display information may be displayed on the left side of the second display area 462, and the second operation unit 42 for operating the second display information may be provided on the first handle unit 281, which is the left handle. In this case, the driver can intuitively recognize that the content 82 displayed on the left side of the second display area 462 can be operated with his or her left hand.

[0115] When the parallel display is performed, it is preferable that the direction from the display position of the first display information to the display position of the second display information coincides with the direction from the accelerator operation unit 34 to the display 38. This allows the driver to intuitively operate the second display information with one hand while operating the accelerator operation unit 34 with the other hand.

[0116] The second display information may include a call list 82C. When the condition determination unit 74 determines that a predetermined condition is met, it is preferable that the display control unit 68 restricts operations on the call list 82C via the second operation unit 42. For example, when the speed of the vehicle 10 is equal to or greater than a speed threshold, the display control unit 68 restricts scrolling operations on the call list 82C. This prevents the driver of the vehicle 10 from paying excessive attention to the display 38.

[0117] One embodiment may be modified as follows. In the following modifications, descriptions that overlap with the embodiment will be omitted as appropriate. In addition, in the drawings used in the following modifications, the same reference numerals are used for the same components as those described in the embodiment.

[0118] (Modification 1) When an icon selection operation is performed, the display control unit 68 may at least temporarily restrict the display of the guidance information 80.

[0119] For example, when an icon selection operation is performed for the first time, the display control unit 68 hides the guidance information 80 and stores information (a flag) indicating that the icon selection operation has been performed for the first time in the non-volatile memory (storage unit 60). The flag is referenced by the display control unit 68 when the vehicle 10 (display control device 52) is restarted. When the flag is stored in the non-volatile memory, the display control unit 68 skips the process for displaying the guidance information 80 on the display 38. In this way, the display control unit 68 does not display the guidance information 80 on the display 38 after the icon selection operation is performed for the first time.

[0120] According to this modification, the display control unit 68 can omit displaying the guidance information 80 for a user who understands the procedure for the icon selection operation. In other words, the display control unit 68 can avoid displaying on the display 38 information that is relatively likely to be unnecessary for the user.

[0121] (Variation 2) When the user performs an erroneous operation on the display operation unit 36, the display control unit 68 may at least temporarily display information on the display 38 to make the user aware of the erroneous operation.

[0122] For example, the second operation unit 42 described above may accept directional inputs along multiple directions, including the longitudinal and lateral directions of the display 38. In contrast, there may be cases where the content 82 operated by the second operation unit 42 does not anticipate directional input in at least one direction. For example, the call list 82C described above lists multiple call partners CA along the lateral direction of the display 38. When a directional input in the longitudinal direction of the display 38 is made to this call list 82C, the display control unit 68 may display information on the display 38 to make the user aware that the directional input is an erroneous operation. In this way, the display control unit 68 can make the user aware of the erroneous operation.

[0123] If the user's operation error is a predetermined directional input, the display control unit 68 may use the guidance information 80 described above as information to allow the user to recognize that the predetermined directional input is an operation error. The predetermined directional input is a directional input in a direction from the second display area 462 toward the first display area 461. For example, if a predetermined directional input is performed even when the content 82 is in a state where the predetermined directional input cannot be accepted, the display control unit 68 may blink the guidance information 80. This allows the user to recognize that the predetermined directional input was an operation error. Furthermore, in relation to the above-described first modification, if the operation error (predetermined directional input) is performed after the guidance information 80 has been hidden, the display control unit 68 may at least temporarily re-display (blink) the guidance information 80. As described above, the guidance information 80 may be displayed in the first display area 461. That is, according to this modification, when a predetermined direction input from second display area 462 toward first display area 461 is an erroneous operation, guidance information 80 can be displayed in first display area 461. This allows the user to intuitively recognize that the predetermined direction input is an erroneous operation.

[0124] Parallel display may be restricted when a user performs a predetermined operation. For example, the user may use a setting screen (see one embodiment) to instruct the display control device 52 not to execute parallel display. In this case, the display control unit 68 may restrict the execution of parallel display.

[0125] (Combination of Multiple Modifications) The multiple modifications described above may be combined as appropriate within a range that does not cause inconsistency.

[0126] The following additional notes are further disclosed regarding the above embodiment.

[0127] (Supplementary Note 1) A display control device (52) according to the present disclosure includes an operation recognition unit (70) that recognizes a selection operation, which is an operation for selecting one of a plurality of pieces of display information that can be displayed on a display (38) provided in a vehicle (10), and a display control unit (68) that causes the display to display the display information selected by the selection operation from the plurality of pieces of display information, wherein, when predetermined first display information from the plurality of pieces of display information is displayed on the display and second display information that is display information other than the first display information from the plurality of pieces of display information is selected by the selection operation, the display control unit executes parallel display to display the second display information together with at least a portion of the first display information on the display. This allows the display control device to continue providing the first display information to the driver while providing the second display information to the driver.

[0128] (Supplementary Note 2) In the display control device according to Supplementary Note 1, the display may be a landscape display, and when the parallel display is performed, the display control unit may display the first display information and the second display information side by side along a longitudinal direction of the display, thereby allowing a driver to easily distinguish between the first display information and the second display information.

[0129] (Supplementary Note 3) The display control device according to Supplementary Note 2 may further display speed information indicating the speed of the vehicle at a center of the longitudinal direction of the display, thereby suppressing line-of-sight movement of the driver facing forward when the driver attempts to visually check the speed information.

[0130] (Supplementary Note 4) In the display control device according to Supplementary Note 3, when the first display information displayed in the parallel display includes turn-by-turn information (84), the display control unit may display the turn-by-turn information in a portion of the area (462A) where the first display information is displayed, which is closer to the center in the longitudinal direction. This can suppress line-of-sight movement of the driver who is facing forward and attempts to visually recognize the turn-by-turn information, even when the parallel display is being executed.

[0131] (Supplementary Note 5) In the display control device according to Supplementary Note 2, the vehicle may be provided with an operation unit (42) that accepts an operation on the second display information, and a direction from a display position of the first display information to a display position of the second display information when the side-by-side display is performed may match a direction from the display to the operation unit along the longitudinal direction.

This may provide a more intuitive sense of operation to the driver.

[0133] (Supplementary Note 7) The display control device according to Supplementary Note 5 may further include a condition determination unit (74) that determines whether a predetermined condition is met, and that limits operations on the call list via the operation unit when the condition determination unit determines that the predetermined condition is met. This prevents a driver of a vehicle from paying excessive attention to the display.

[0134] (Supplementary Note 8) In the display control device according to Supplementary Note 7, the predetermined condition may be that the speed of the vehicle is equal to or greater than a predetermined speed threshold. This prevents the driver from paying excessive attention to the display when the speed of the vehicle is equal to or greater than the speed threshold.

This allows the computer to continue providing the first display information to the driver while providing the second display information to the driver.

[0137] (Supplementary Note 11) A program according to the present disclosure is a program for causing a computer to execute the display control method described in Supplementary Note 10. This allows the computer to continue providing the first display information to the driver while providing the second display information to the driver.
