Detailed description

[0029] A detailed explanation will now be given regarding an example of an exemplary embodiment of the present disclosure with reference to the drawings. As shown in Fig. 1, an on-board system 10 includes a bus 12. A touchscreen 14, an air conditioner 16, a camera 18, an electronic voice recognition control unit (ECU) 20, a steering wheel switch 22, and an air conditioning control ECU 24 are connected to the bus 12, respectively. It should be noted that Fig. 1 only shows portions of the on-board system 10 that are relevant to the present disclosure.

[0030] The touch screen 14 is arranged at a central portion of a vehicle instrument panel and serves as a central display of the vehicle. As shown in Fig. As shown in Figure 2, a display area of ​​the touch screen 14 is divided into a first area 14A at the bottom in a vehicle vertical direction and a second area 14B at the top in the vehicle vertical direction. When an ignition switch of the vehicle is turned on, an air conditioning operation section 50 is displayed in the first area 14A, which enables input of instructions for the air conditioner 16 via the air conditioning control ECU 24.

[0031] The air conditioning operation section 50 includes a plurality of virtual buttons 52. The plurality of virtual buttons 52 of the air conditioning operation section 50 includes switching buttons 52A that enable an instruction to switch between blower modes (air flow outlets) of the conditioned air by the air conditioner 16, a slider 52B that enables an instruction to switch the flow rate of the conditioned air by the air conditioner 16, and so on. The display position of the slider 52B on the touch screen 14 is movable. Performing an input operation to move this display position (a swipe on the slider 52B) enables an instruction to switch the flow rate. Note that the virtual buttons 52 of the air conditioning operation section 50 correspond to an example of a first operation section.

[0032] As in Fig. As shown in Fig. 2, the rotary switches 54 are provided near both end portions in the vehicle width direction of a lower end portion in the vehicle vertical direction of the touch panel 14. Each of the rotary switches 54 protrudes from the display surface of the touch panel 14, can be rotated about an axis extending along a vehicle longitudinal direction, and enables, for example, an instruction or specification of a target temperature of the conditioned air from the air conditioner 16. Note that the rotary switches 54 correspond to an example of a second operation section.

[0033] The air conditioner 16 is capable of independently performing air conditioning on a driver's seat side and a passenger's seat side of the vehicle. The camera 18 captures images (moving images) of the surroundings of the vehicle. The images captured by the camera 18 are displayed in the second area 14B of the touch screen 14 at predetermined timings. Examples of such predetermined timings include a timing at which the vehicle performs processing to automatically park the vehicle. An image captured by the camera 18 and displayed in the second area 14B of the touch screen 14 corresponds to an example of predetermined high-priority information (display). Note that the camera 18 corresponds to an example of an image capture section.

[0034] A microphone (not shown) is connected to the voice recognition ECU 20. The voice recognition ECU 20 performs voice recognition processing to recognize the voice spoken by a user on board the vehicle. In the present exemplary embodiment, the user is able to input voice instructions for the air conditioner 16 or the like. In cases where the recognized voice is a voice instruction for the air conditioner 16, the voice recognition ECU 20 outputs the content of the voice instruction to the air conditioning control ECU 24. When various voice recognition settings are applied using the voice recognition ECU 20, the voice recognition ECU 20 displays a voice recognition setting screen in the second area 14B of the touch screen 14.The voice recognition setting screen displayed in the second area 14B of the touch screen 14 corresponds to an example of predetermined high priority information (display).

[0035] The steering wheel switch 22 is provided on a steering wheel of the vehicle. In the present exemplary embodiment, instructions for the air conditioner 16 can also be input by operating the steering wheel switch 22. Instructions for the air conditioner 16 input via the steering wheel switch 22 are output to the climate control ECU 24. The steering wheel switch 22 corresponds to an example of a switch provided on a device other than the touch screen.

[0036] The air conditioning control ECU 24 includes a central processing unit (CPU) 26, a memory 28 such as a read-only memory (ROM) or a random access memory (RAM), a non-volatile storage section 30 such as a hard disk drive (HDD) or a solid state drive (SSD), and a communication section 32. The CPU 26, the memory 28, the storage section 30, and the communication section 32 are connected to be able to communicate with each other via an internal bus 34.

[0037] An air conditioning control program 36 is stored in the memory section 30 of the air conditioning control ECU 24. The air conditioning control ECU 24 reads the air conditioning control program 36 from the memory section 30 and expands the air conditioning control program 36 into the memory 28. The air conditioning control program 36 expanded into the memory 28 is executed by the CPU 26, so that the air conditioning control ECU 24 serves as a display control section 38 and a prohibition section 40, as shown in Fig. 3, and performs the air conditioning control processing described later. Note that the air conditioning control ECU 24, together with the touch screen 14, serves as an example of a display device. The air conditioning control program 36 corresponds to an example of a display program.

[0038] In cases where an input operation is performed using one of the virtual buttons 52 of the air conditioning operation section 50 displayed on the touch screen 14 or one of the rotary switches 54 provided on the touch screen 14, the display control section 38 displays an icon or symbol according to an instruction resulting from the input operation using the virtual button 52 or the rotary switch 54 on the touch screen 14. In cases where a specific condition described later is met, the prohibition section 40 prohibits the display control section 38 from displaying the icon on the touch screen 14.

[0039] The following is an explanation regarding specific examples of icon display by the display control section 38. In cases where a touch operation has been performed using one of the switching buttons 52A of the air conditioning operation section 50 to switch the air conditioner 16 to a blower mode in which an air flow is blown only through an upper blower outlet of the air conditioner 16, the display control section 38 displays an icon 56 near the corresponding switching button 52A, as in the example in Fig. 4. Icon 56 includes a single arrow indicating the airflow through the upper fan outlet. As shown in the example in Fig. 5, the display control section 38 progressively shifts the display position of the arrow within the icon 56 along the direction in which the arrow points while the icon 56 is displayed on the touch screen 14.

[0040] In cases where a touch operation has been performed using one of the switching buttons 52A of the air conditioning operation section 50 to switch the air conditioner 16 to a blower mode in which an airflow is blown through both the upper blower outlet and a lower blower outlet of the air conditioner 16, the display control section 38 displays an icon 58 near the corresponding switching button 52A, as in the example in Fig. 6. Icon 58 includes an arrow indicating the airflow through the upper fan outlet and an arrow indicating the airflow through the lower fan outlet. As shown in the example in Fig. 7, the display control section 38 progressively shifts the display positions of the two arrows in the icon 58 along the respective directions in which the arrows point while the icon 58 is displayed on the touch screen 14.

[0041] In cases where an input operation has been performed on the slider 52B of the air conditioning operation section 50 by moving the display position of the slider 52B to instruct switching of the flow rate of the conditioned air by the air conditioner 16, the display control section 38 displays an icon 60 near the slider 52B, as in the example in Fig. 8. The icon 60 contains a numerical value that indicates the flow rate. As in the example in Fig. 9, the display control section 38 moves the display position of the icon 60 on the touch screen 14 to follow the movement of the slider 52B, and adjusts the numerical value indicating the flow rate within the icon 60 whenever an input operation for moving the display position of the slider 52B is performed.

[0042] As in the example in Fig. As shown in Figure 10, in cases where an input operation has been performed using one of the rotary switches 54 provided on the touch panel 14 by rotating the corresponding rotary switch 54 to instruct a change in the target temperature of the conditioned air by the air conditioner 16, the display control section 38 displays an icon 62 near the rotary switch 54. The icon 62 includes a numerical value indicating the target temperature. The display control section 38 adjusts the numerical value within the icon 62 indicating the target temperature whenever an input operation for rotating the rotary switch 54 is performed.

[0043] It should be noted that icons 62 corresponding to the left and right rotary switches 54 provided on the touch screen 14 are in Fig. 10 are displayed accordingly. In cases where the air conditioning system 16 has been set to a driving state in which the air conditioning is synchronized between the driver's seat side and the passenger's seat side of the vehicle, a left and right pair of the corresponding icons are displayed when an input operation is performed using one of the virtual buttons 52 or one of the rotary switches 54, as in Fig. 10 is shown.

[0044] The Fig. 4 and Fig. 5 icons 56 shown in Fig. 6 and Fig. 7 icons 58 shown in Fig. 8 and Fig. 9 shown icons 60 and those in Fig. The icons 62 shown in Figure 10 are merely examples of icons displayed by the display control section 38. That is, the display control section 38 also displays icons on the touch screen 14 when input operations are performed on virtual buttons 52 other than the toggle buttons 52A and the slider 52B of the air conditioning control section 50.

[0045] Next, as an operation of the present exemplary embodiment, an explanation will be given regarding air conditioning control processing executed by the air conditioning control ECU 24 while the ignition switch of the vehicle is turned on, with reference to FIG. Fig. 11.

[0046] In step 100 of the air conditioning control processing, the display control section 38 displays the air conditioning operation section 50 including the plurality of virtual buttons 52 in the first area 14A of the touch screen 14. In the next step 102, the prohibition section 40 determines whether or not an instruction for the air conditioner 16 has been input. The processing of step 102 is repeated in cases where a negative determination is made in step 102. In cases where an instruction for the air conditioner 16 has been input, an affirmative determination is made in step 102, and the processing proceeds to step 104.

[0047] In step 104, the prohibition section 40 determines the source of the input instruction for the air conditioner 16, and the processing branches according to the input source of the instruction for the air conditioner 16. The processing proceeds from step 104 to step 106 in cases where the instruction for the air conditioner 16 was input by an input operation using one of the virtual buttons 52 or the rotary switches 54.

[0048] In step 106, the prohibition section 40 determines whether or not high priority display is performed in the second area 14B of the touch screen 14.

[0049] In cases where a negative determination is made in step 106, processing proceeds to step 108.

[0050] In step 108, the display control section 38 displays an icon (for example, one of the previously described icons 56, 58, 60, and 62) corresponding to the input operation using the corresponding virtual button 52 or the rotary switch 54 on the touch screen 14. This allows the user to check the content of the instruction for the air conditioner 16 following the input operation by looking at the icon displayed on the touch screen 14.

[0051] In step 110, in response to the input instruction, the display control section 38 changes the air conditioning state displayed on the touch screen 14 to alert the user of the changed air conditioning state. For example, in cases where a touch operation was performed using one of the switching buttons 52A of the air conditioning operation section 50 to switch between blower modes of the air conditioner 16, the display control section 38 changes the icon displayed near the corresponding switching button 52A to an icon corresponding to the blower mode of the air conditioner 16 after the switching.

[0052] In step 112, the display control section 38 controls the action of the air conditioner 16 in response to the input instruction. In step 114, the display control section 38 deletes the icon displayed on the touch screen 14 in step 108 after a predetermined period of time has elapsed since the instruction for the air conditioner 16 was input. Processing returns to step 102 after the processing of step 114 is performed.

[0053] Processing proceeds from step 104 to step 116 in cases where it is determined at step 104 that the instruction for the air conditioner 16 was input by performing a voice input operation or an input operation using the steering wheel switch 22 (corresponding to examples of an instruction equivalent to an input operation using one of the virtual buttons 52 or the rotary switches 54). Cases where a voice input operation or an input operation using the steering wheel switch 22 was performed are examples of cases where a specific condition was met.

[0054] The processing proceeds in cases where a determination is made in step 106 that high priority display is being performed, for example, in cases where an image 64 captured by the camera 18 is displayed in the second area 14B of the touch screen 14, as in the example in Fig. 12, and in cases where a voice recognition setting screen 66 is displayed in the second area 14B of the touch screen 14, as in the example in Fig. 13, from step 106 to step 116. Cases in which high-priority display is performed in the second area 14B of the touch screen 14 are examples of cases in which a specific condition has been met.

[0055] In step 116, the display control section 38 changes the air conditioning state displayed on the touch screen 14 in response to the input instruction to alert the user of the changed air conditioning state, similar to the previously described step 110. In step 118, the display control section 38 controls the action of the air conditioner 16 in response to the input instruction, similar to the previously described step 112. The processing returns to step 102 after the processing of step 118 is performed.

[0056] In this way, icon display on the touch screen 14 by the display control section 38 is prohibited in cases where the instruction for the air conditioner 16 is input by performing a voice input operation or an input operation using the steering wheel switch 22. Icon display on the touch screen 14 by the display control section 38 is also prohibited in cases where high-priority display is performed in the second area 14B of the touch screen 14.

[0057] As described above, in the present exemplary embodiment, the touch screen 14 is provided. In cases where an input operation has been performed using one of the virtual buttons 52 displayed on the touch screen 14 or one of the rotary switches 54 provided with the touch screen 14, the display control section 38 displays the icon according to the instruction resulting from the input operation using the corresponding virtual button 52 or the rotary switch 54 on the touch screen 14. The prohibition section 40 prohibits icon display by the display control section 38 in cases where a specific condition is met. Prohibiting icon display in this way in cases where a specific condition is met enables suppressing unnecessary icon display that the user may find annoying.

[0058] In the present exemplary embodiment, cases where a specific condition has been met include cases where predetermined high-priority information is displayed on the touch screen 14. Thus, prohibiting icon display in cases where predetermined high-priority information is displayed on the touch screen 14 allows the user to more easily recognize the high-priority information.

[0059] In the present exemplary embodiment, the touch screen 14 is provided inside the vehicle cabin of the vehicle, and the predetermined high-priority information corresponds to an image of the surroundings of the vehicle captured by the camera 18. Thus, prohibiting icon display in cases where an image capturing the surroundings of the vehicle is displayed on the touch screen 14 makes it easier for the user on board the vehicle to recognize the situation around the vehicle.

[0060] In the present exemplary embodiment, cases where a specific condition has been satisfied include cases where an instruction equivalent to an input operation using one of the virtual buttons 52 or the rotary switches 54 has been performed by an operation other than an input operation using one of the virtual buttons 52 or the rotary switches 54. In cases where an operation has been performed by an operation other than an input operation using one of the virtual buttons 52 or the rotary switches 54, the user can know the content of the instruction resulting from that operation without the corresponding icon being displayed. Accordingly, unnecessary icon display that the user might find annoying can be suppressed.

[0061] In the present exemplary embodiment, an operation other than an input operation using one of the virtual buttons 52 or the rotary switches 54 corresponds to a voice input operation. Accordingly, an icon display that may be annoying to the user who has performed the voice input can be suppressed.

[0062] In the present exemplary embodiment, an operation other than an input operation using one of the virtual buttons 52 or the rotary switches 54 corresponds to an input operation using a switch provided on an input device other than the touch screen 14. Accordingly, an icon display that may be annoying to the user who performed the input operation using the switch provided on an input device other than the touch screen 14 can be suppressed.

[0063] In the present exemplary embodiment, in cases where an input operation using one of the virtual buttons 52 corresponds to an input operation for moving the slider 52B, which has a movable display position on the touch screen 14, the display control section 38 moves the display position of the corresponding icon on the touch screen 14 to follow the movement of the slider 52B. By moving the display position of the icon to follow the movement of the slider 52B, the amount the user needs to shift their gaze to view the slider 52B or the icon can be reduced.

[0064] In the present exemplary embodiment, in cases where an icon including an arrow is displayed on the touch screen 14, the display control section 38 progressively shifts the display position of the arrow within the icon along the direction the arrow points. This allows the user to be aware of the direction the arrow points within the icon.

[0065] In the above description, the image 64 taken by the camera 18 ( Fig. 12) and the voice recognition setting screen 66 ( Fig. 13) are explained as examples of the high-priority display, during which icon display on the touch screen 14 is prohibited. However, the high-priority display is not limited to this. For example, the high-priority display may be associated with an emergency alarm screen 68 for warning that an emergency situation has occurred, as shown in Fig. 14, or a locked screen 70 used for anti-theft protection, as shown in Fig. 15.

[0066] 18In the above description, the steering wheel switch 22 was explained as an example of a switch provided on an input device other than the touch panel 14. However, there is no limitation, and such a switch may be provided on the instrument panel or the like.

[0067] In the above description, an embodiment has been explained in which the air conditioning operation section 50 is displayed in the first area 14A of the touch screen 14, and the air conditioning control ECU 24, which controls the action of the air conditioner 16, serves as the display control section 38 and the prohibition section 40 of the display device. However, there is no limitation in this regard. For example, an audio operation screen may be displayed on the touch screen 14, and an audio control ECU, which controls the action of audio equipment in response to input operations on the audio operation screen or the like, may be made to serve as the display control section 38 and the prohibition section 40.

[0068] In the above description, an embodiment in which the touch screen 14 is arranged at the central portion of the vehicle's instrument panel was explained. However, there is no limitation in this regard. For example, the touch screen 14 may be configured by a display portion such as a smartphone or a tablet, and a CPU embedded in the smartphone or tablet may be made to serve as the display control portion 38 and the prohibition portion 40.

[0069] In the above description, an embodiment was explained in which the air conditioning control program 36, which serves as an example of a display program according to the present disclosure, is pre-stored (installed) in the storage section 30.
