[0045] The CPU 20A is a central processing unit and executes various programs or controls various components. That is, the CPU 20A as a processor reads a program from the ROM 20B as a memory and executes the program using the RAM 20C as a work area.

[0046] ROM 20B stores various programs and various data. In the ROM 20B of the present embodiment, a control program 100 is stored. The control program 100 is a program for controlling the solar ECU 20 .

[0047] The RAM 20C temporarily stores programs or data as a work area.

[0050] In addition, the solar ECU 20 may include a storage device as a memory in addition to or in place of the ROM 20B. The storage device may be constituted by, for example, a HDD (Hard Disk Drive) or an SSD (Solid State Drive).

[0051] like Figure 3 As shown, in the solar ECU 20 of the present embodiment, the CPU 20A functions as the acquisition unit 200 , the control unit 210 , and the calculation unit 220 by executing the control program 100 .

[0052] The acquisition unit 200 has a function of acquiring the instantaneous amount of power generated by the solar panel 14 mounted on the vehicle 12 .

[0053] The control unit 210 has a function of causing the meter 30 to display the state of the power generated by the solar panel 14. The control unit 210 of this embodiment causes the display area PA (see FIG. 14 ) displayed on the meter 30 to display the state of the power generated by the solar panel 14 according to the instantaneous power generation acquired by the acquisition unit 200. Figure 5 ) area changes. In addition, the control unit 210 causes the meter 30 to display the drivable distance calculated by the calculation unit 220.

[0054] The calculation unit 220 has a function of calculating the drivable distance of the vehicle 12 based on the cumulative amount of electric power generated by the solar panel 14. The calculation unit 220 is an example of a vehicle calculation unit.

[0055] (Control Process)

This display control process is implemented by the CPU 20A functioning as the acquisition unit 200, the control unit 210, and the calculation unit 220 described above.

[0057] exist Figure 4 In step S100 , the CPU 20A obtains the instantaneous power generation of the solar panel 14 .

[0058] In step S101 , the CPU 20A calculates the cumulative amount of power generated by the vehicle 12 since the last time the vehicle 12 traveled.

[0059] In step S102, the CPU 20A calculates the usable amount based on the accumulated power generation amount. In the present embodiment, the usable amount is the travelable distance of the vehicle 12.

[0060] In step S103 , the CPU 20A causes the meter 30 to display the instantaneous power generation amount and the drivable distance as the usable amount, and then returns to step S100 .

[0061] The result of step S103 is as follows: Figure 5As shown, the display area PA indicating the instantaneous power generation amount and the information SD related to the travel distance are displayed on the meter 30. The display area PA is displayed as a ratio relative to the maximum area PB indicating the preset maximum amount. In addition, the maximum area PB only needs to show that the power generation implemented by the solar panel 14 can be fully completed. Even if the instantaneous power generation exceeds the maximum amount corresponding to the maximum area PB, the display area PA is displayed in a manner to maintain the maximum area PB.

[0062] (Summary of Implementation Methods)

[0063] In the solar ECU 20 of the present embodiment, the control unit 210 changes the area of ​​the display region PA displayed on the meter 30, that is, the length of the strip-shaped image, based on the instantaneous power generation acquired by the acquisition unit 200. Therefore, according to the present embodiment, when the solar panel 14 mounted on the vehicle 12 generates power, the instantaneous power generation can be intuitively communicated to the occupant who is the user of the vehicle 12.

[0064] Furthermore, in the solar ECU 20 of the present embodiment, when the calculation unit 220 calculates the drivable distance of the vehicle 12 based on the power generated by the solar panel 14, the control unit 210 causes the meter 30 to display the drivable distance. Therefore, according to the present embodiment, not only the instantaneous power generation amount but also the drivable distance of the vehicle 12 as a result of the integration of the instantaneous power generation amount can be provided to the occupant.

[0065] [Second Embodiment]

[0066] In the first embodiment, the meter 30 displays the drivable distance of the vehicle 12 as the usable amount, but in the second embodiment, the meter 30 displays the usable amount of a device (hereinafter referred to as an "external device") outside the vehicle 12 as the usable amount. The differences from the first embodiment will be described below. In addition, the same symbols are attached to the same structures, and detailed descriptions are omitted.

[0067] Examples of the external device in this embodiment include portable terminals such as smartphones and personal computers, and home appliances such as rice cookers and hair dryers.

[0068] The control unit 210 of the present embodiment can cause the meter 30 to display the usable amount of the external device calculated by the calculation unit 220. The usable amount includes the usable time and the number of times.

[0069] The calculation unit 220 of the present embodiment has a function of calculating the usable amount of the external device based on the cumulative amount of electric power generated by the solar panel 14. The calculation unit 220 is an example of a device calculation unit.

[0070] In the display control process of this embodiment, Figure 4 In step S102, the number of times the smartphone as the external device can be charged is calculated as the usable amount. In step S103, the CPU 20A causes the meter 30 to display the instantaneous power generation amount and the number of times the smartphone can be charged as the usable amount.

[0071] The result of step S103 is as follows: Figure 6 As shown, the meter 30 displays a display area PA indicating the instantaneous power generation amount and information SQ related to the number of times the smartphone can be charged.

[0072] In the solar ECU 20 of the present embodiment, when the calculation unit 220 calculates the amount of external devices that can be used based on the amount of power generated by the solar panel 14, the control unit 210 causes the meter 30 to display the number of times the smartphone can be charged. Therefore, according to the display control device, not only the instantaneous power generation amount can be provided to the occupant who is the user of the vehicle 12, but also the amount of external devices that can be used as a result of the integration of the instantaneous power generation amount can be provided to the occupant.

[0073] [Third Embodiment]

[0074] In the first and second embodiments, the meter 30 displays the available amount together with the instantaneous power generation, but in the third embodiment, the meter 30 displays information that the power generation of the solar panel 14 is maximized when the vehicle 12 is parked. The differences from the first embodiment are described below. In addition, the same symbols are used for the same configurations, and detailed descriptions are omitted.

[0075] like Figure 7 As shown, in the solar ECU 20 of the present embodiment, the CPU 20A functions as the acquisition unit 200 , the control unit 210 , the calculation unit 220 , the estimation unit 230 , and the determination unit 240 by executing the control program 100 .

[0076] The acquisition unit 200 of the present embodiment has a function of acquiring data on the direction and parking position of the vehicle 12 from the car navigation system 32 in addition to acquiring the instantaneous power generation amount.

[0077] The control unit 210 of the present embodiment causes the meter 30 to display information on the parking direction of the vehicle 12 determined by the determination unit 240 described later.

[0078] The estimation unit 230 has a function of estimating the instantaneous power generation amount for each orientation of the vehicle 12. Specifically, the estimation unit 230 estimates the instantaneous power generation amount for each of 16 orientations, for example, based on the instantaneous power generation amount for the current orientation of the vehicle 12.

[0079] The determination unit 240 has a function of determining a parking direction of the vehicle 12 in which the instantaneous power generation estimated by the estimation unit 230 becomes the maximum with respect to the scheduled parking position of the vehicle 12. For example, the determination unit 240 determines a parking direction in which the instantaneous power generation is greater when the parking direction is forward or reverse with respect to the parking space where the vehicle 12 is to be parked from now on.

[0080] Next, use Figure 8 The flow of the display control process executed in the solar ECU 20 of the present embodiment will be described with reference to the flowchart of FIG. The display control process is implemented by the CPU 20A functioning as the acquisition unit 200, the control unit 210, the calculation unit 220, the estimation unit 230, and the determination unit 240 described above.

[0081] exist Figure 8 In step S200 , the CPU 20A obtains the instantaneous power generation of the solar panel 14 .

[0082] In step S201 , the CPU 20A obtains the direction of the vehicle 12 from the car navigation system 32 .

[0083] In step S202 , the CPU 20A estimates the instantaneous power generation amount for each direction of the vehicle 12 .

[0084] In step S203 , the CPU 20A determines a parking direction recommended for the planned parking position.

[0085] In step S204, CPU 20A causes meter 30 to display the instantaneous power generation amount and the recommended parking direction, and then returns to step S200.

[0086] The result of step S204 is as follows: Fig. 9 As shown in FIG. 1 , the meter 30 displays a display area PA showing the instantaneous power generation, an estimated instantaneous power generation PC, and information PI related to the recommended parking direction. The estimated instantaneous power generation PC is the instantaneous power generation estimated when the vehicle 12 is parked in the recommended parking direction. In addition, in the information PI related to the recommended parking direction, the instantaneous power generation that increases when the vehicle is parked in the recommended parking direction is displayed together with the recommended parking direction.

[0087] In the solar ECU 20 of the present embodiment, the estimation unit 230 estimates the instantaneous power generation for each orientation of the vehicle 12, and the determination unit 240 determines the parking direction in which the estimated instantaneous power generation becomes the maximum relative to the predetermined parking position. Then, the control unit 210 causes the meter 30 to display information on the determined parking direction. According to the present embodiment, by communicating the parking direction in which the instantaneous power generation becomes the maximum to the occupant who is the user of the vehicle 12 before parking the vehicle 12, it is possible to increase the power generation when parking.

[0088] [Remark]

[0089] In addition, although in each of the above-mentioned embodiments, the display unit, i.e., the meter 30, provided on the vehicle 12 displays information such as instantaneous power generation, the display unit for displaying is not limited thereto. For example, the display of the vehicle navigation system 32 may be used as a display unit to display information such as instantaneous power generation. For another example, the screen of a smartphone may be used as a display unit to display information such as instantaneous power generation. In this case, the vehicle 12 has a DCM (Data Communication Module) connected to the communication I / F 20E of the solar ECU 20, and is connected to a network such as 5G, LTE, or Wi-Fi (registered trademark) through the DCM, so that the smartphone can display information.

[0090] Furthermore, the above-mentioned embodiments may be combined. For example, the first embodiment and the second embodiment may be combined so that the meter 30 displays the drivable distance of the vehicle 12 and the number of times the smartphone can be charged, together with the instantaneous power generation.

[0091] In addition, various processors other than the CPU can also perform various processes that the CPU20A reads the software (program) and executes in the above-mentioned embodiments. As processors in this case, FPGA (Field-Programmable Gate Array) and other PLDs (Programmable Logic Devices) whose circuit structures can be changed after manufacturing, and ASICs (Application Specific Integrated Circuits) and other processors with circuit structures specially designed for performing specific processes, i.e., dedicated circuits, etc. can be exemplified. In addition, the above-mentioned processes can be performed by one of these various processors, or by a combination of two or more processors of the same or different types (for example, a plurality of FPGAs, and a combination of a CPU and an FPGA, etc.). In addition, the hardware structure of these various processors is more specifically a circuit composed of a combination of circuit elements such as semiconductor elements.

[0092] In addition, in each of the above-mentioned embodiments, the program is described in a manner that is pre-stored (installed) in a non-temporary storage medium that is readable by a computer. For example, the control program 100 in the solar ECU 20 is pre-stored in the ROM 20B. However, it is not limited to this, and each program can also be provided in the form of being stored in a non-temporary storage medium such as a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM (Digital Versatile Disc Read Only Memory), and a USB (Universal Serial Bus) memory. In addition, the program can also be set to a form downloaded from an external device via a network.
