[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0011] <Embodiment> [Configuration example] 1 shows an example of the configuration of a vehicle 1 equipped with a sunshade device (sunshade device 10) according to one embodiment. In this example, the vehicle 1 is a vehicle powered by an engine. The vehicle 1 includes an ignition switch 2, an ECU (Electronic Control Unit) 3, an auxiliary battery 4, a solar cell 11, a power storage device 12, a control circuit 13, a drive device 14, and a sunshade 15. The solar cell 11, the power storage device 12, the control circuit 13, the drive device 14, and the sunshade 15 constitute the sunshade device 10.

[0012] The ignition switch 2 is configured to start or stop the engine of the vehicle 1 by switching on or off the switch state based on the driver's operation. The ignition switch 2 supplies information about the switch state to the ECU 3.

[0013] The ECU 3 is configured using, for example, one or more processors, one or more memories, etc., and is configured to control the operation of the vehicle 1. The ECU 3 also supplies information about the switch state supplied from the ignition switch 2 to the control circuit 13.

[0014] The auxiliary battery 4 is configured to store electric power and to supply the stored electric power to various electrical components (not shown) such as a drive recorder and audio equipment, and the drive device 14, for example.

[0015] The solar cell 11 is configured to generate electric power based on sunlight and to supply the generated electric power to the power storage device 12.

[0016] The power storage device 12 has a battery 121 and a power sensor 122. The battery 121 is configured to store the power supplied from the solar cell 11 and to supply the stored power to the drive device 14. The power sensor 122 is configured to detect the amount of power supplied from the solar cell 11. In other words, the power sensor 122 detects the amount of power generated by the solar cell 11. The power sensor 122 then supplies information about the detected amount of power generated to the control circuit 13.

[0017] The control circuit 13 is configured using one or more processors and one or more memories, and is configured to control the operation of the sunshade device 10. The control circuit 13 has a driving-possible state determination unit 131, a power generation amount determination unit 132, and a sunshade control unit 133.

[0018] The drivable state determination unit 131 is configured to determine whether the vehicle 1 is in a drivable state based on information about the switch state of the ignition switch 2 supplied from the ECU 3. Specifically, when the switch state of the ignition switch 2 is in the on state, the drivable state determination unit 131 determines that the vehicle 1 is in a drivable state because the engine is running. On the other hand, when the switch state of the ignition switch 2 is in the off state, the drivable state determination unit 131 determines that the vehicle 1 is not in a drivable state because the engine is stopped.

[0019] The power generation amount determination unit 132 is configured to determine whether the power generation amount of the solar cell 11 is equal to or greater than a threshold value TH1 based on the power generation amount detected by the power sensor 122. This threshold value TH1 is a value that serves as a power generation amount reference for determining whether or not to deploy the sunshade 15, as will be described later.

[0020] The sunshade control unit 133 is configured to determine whether to deploy or retract the sunshade 15 based on the determination results of the travel-enabled state determination unit 131 and the power generation amount determination unit 132. The sunshade control unit 133 then issues an instruction to the drive unit 14 according to this determination result. The sunshade control unit 133 also stores information on whether the state of the sunshade 15 is deployed or retracted.

[0021] The sunshade 15 is provided in the passenger compartment of the vehicle 1 and is configured to block sunlight by being deployed to cover the windshield of the vehicle 1. The sunshade 15 has, for example, a bellows structure and is folded and stored in positions near the left and right ends of the windshield. However, the present invention is not limited to this. The sunshade 15 may have, for example, a roll structure and be rolled up and stored in positions near the left and right ends of the windshield. The sunshade 15 is deployed or stored by being driven by the drive unit 14. Although the sunshade 15 is configured to be stored in positions near the left and right ends of the windshield in this example, the present invention is not limited to this. Instead, the sunshade 15 may be stored in positions near the top and bottom ends of the windshield. Furthermore, although the sunshade 15 is deployed to cover the windshield, the present invention is not limited to this. Instead, the sunshade 15 may be deployed to cover, for example, the door windows or the rear window.

[0022] The drive device 14 is configured to drive the sunshade 15 to deploy or retract the sunshade 15 based on an instruction from the sunshade control unit 133 of the control circuit 13. The drive device 14 has, for example, a motor, and deploys the sunshade 15 by operating the motor based on power supplied from the battery 121. The drive device 14 also retracts the sunshade 15 by operating the motor based on power supplied from the auxiliary battery 4.

[0023] Here, solar cell 11 corresponds to a specific example of "solar cell" in an embodiment of the present disclosure. Power sensor 122 corresponds to a specific example of "sensor" in an embodiment of the present disclosure. Sunshade 15 corresponds to a specific example of "sunshade" in an embodiment of the present disclosure. Drive device 14 corresponds to a specific example of "drive device" in an embodiment of the present disclosure. Threshold value TH1 corresponds to a specific example of "first threshold value" in an embodiment of the present disclosure. Control circuit 13 corresponds to a specific example of "processing circuit" in an embodiment of the present disclosure. Battery 121 corresponds to a specific example of "battery" in an embodiment of the present disclosure.

[0024] [Actions and Actions] Next, the operation and function of the vehicle 1 equipped with the sunshade device 10 of this embodiment will be described.

[0025] (Overview of overall operation) First, an overview of the overall operation of vehicle 1 will be described with reference to FIG. 1. An ignition switch 2 starts or stops the engine of vehicle 1 by turning its switch state on or off based on the driver's operation. The ignition switch 2 then supplies information about the switch state to ECU 3. ECU 3 controls the operation of vehicle 1. The ECU 3 also supplies the information about the switch state supplied from the ignition switch 2 to a control circuit 13. The auxiliary battery 4 stores power and supplies the stored power to a drive device 14. The solar cell 11 generates power based on sunlight and supplies the generated power to a battery 121. The battery 121 of the power storage device 12 stores power supplied from the solar cell 11 and supplies the stored power to the drive device 14. A power sensor 122 of the power storage device 12 detects the amount of power generated by the solar cell 11. The power sensor 122 then supplies information about the detected amount of power generated to the control circuit 13. The control circuit 13 controls the operation of the sunshade device 10 based on information about the switch state of the ignition switch 2 and information about the amount of power generated by the solar cell 11. The drive device 14 drives the sunshade 15 to deploy or retract the sunshade 15 based on instructions from the control circuit 13. The sunshade 15 is deployed to cover the front windshield of the vehicle 1, or retracted to positions near the left and right ends of the windshield.

[0026] (Detailed operation) 2 shows an example of the operation of the sunshade device 10. The sunshade device 10 periodically performs the following processing.

[0027] First, the drivable state determination unit 131 of the control circuit 13 determines whether the vehicle 1 is in a drivable state based on information about the switch state of the ignition switch 2 supplied from the ECU 3 (step S101). Specifically, when the switch state of the ignition switch 2 is in the on state, the drivable state determination unit 131 determines that the vehicle 1 is in a drivable state because the engine is running. On the other hand, when the switch state of the ignition switch 2 is in the off state, the drivable state determination unit 131 determines that the vehicle 1 is not in a drivable state because the engine is stopped.

[0028] In step S101, if the travelable state determination unit 131 determines that the vehicle 1 is not in a travelable state ("N" in step S101), the sunshade control unit 133 of the control circuit 13 determines whether the sunshade 15 is stored (step S102). That is, since the sunshade control unit 133 stores the state of the sunshade 15, it determines whether the sunshade 15 is stored based on this stored information. If the sunshade control unit 133 determines that the sunshade 15 is not stored ("N" in step S102), this process ends.

[0029] In step S102, if the sunshade control unit 133 determines that the sunshade 15 is stored ("Y" in step S102), the power generation amount determination unit 132 of the control circuit 13 determines whether the power generation amount of the solar cell 11 detected by the power sensor 122 is equal to or greater than the threshold value TH1 (step S103). If the power generation amount determination unit 132 determines that the power generation amount of the solar cell 11 is not equal to or greater than the threshold value TH1 ("N" in step S103), this process ends.

[0030] In step S103, if the power generation amount determination unit 132 determines that the power generation amount of the solar cell 11 is equal to or greater than the threshold value TH1 ("Y" in step S103), the sunshade device 10 deploys the sunshade 15 (step S104). Specifically, the sunshade control unit 133 determines that the sunshade 15 should be deployed, and the drive unit 14 deploys the sunshade 15 by operating the motor using power supplied from the battery 121 based on an instruction from the sunshade control unit 133.

[0031] On the other hand, if the travelable state determination unit 131 determines in step S101 that the vehicle 1 is in a travelable state ("Y" in step S101), the sunshade control unit 133 determines whether the sunshade 15 is deployed (step S105). If the sunshade control unit 133 determines that the sunshade 15 is not deployed ("N" in step S105), this process ends.

[0032] In step S105, if the sunshade control unit 133 determines that the sunshade 15 is deployed ("Y" in step S105), the sunshade device 10 stores the sunshade 15 (step S106). Specifically, the sunshade control unit 133 determines that the sunshade 15 should be stored, and the drive unit 14 stores the sunshade 15 by operating the motor using power supplied from the auxiliary battery 4 based on the instruction from the sunshade control unit 133.

[0033] This completes the process.

[0034] As described above, the sunshade device 10 includes a solar cell 11 that is provided in the vehicle 1 and capable of generating electricity from sunlight, a power sensor 122 that can detect the amount of power generated by the solar cell 11, a sunshade 15 that is provided in the passenger compartment of the vehicle 1 and can be deployed to cover the window of the vehicle 1 to block sunlight and can be stored in a position corresponding to the edge of the window, a drive unit 14 that can drive the sunshade 15 to deploy and retract, and a control circuit 13 that can control the drive unit 14 to deploy the sunshade 15 when the amount of power generated is equal to or greater than the threshold value TH1 when the vehicle 1 is not in a driving state. This allows the sunshade device 10 to improve user convenience.

[0035] For example, if a user manually deploys a sunshade, forgetting to deploy the sunshade will result in sunlight not being blocked, causing the temperature inside the vehicle to rise. As a result, the user who gets into the vehicle may suffer from heatstroke or other adverse physical conditions. On the other hand, the sunshade device 10 can automatically deploy the sunshade 15, preventing the interior of the vehicle 1 from becoming too hot. This improves user convenience.

[0036] Furthermore, when the user temporarily leaves the vehicle, the user may decide that it is not necessary to deploy the sunshade. In such a case, for example, when the deployment of the sunshade becomes necessary due to a change in the weather, the sunshade cannot be deployed because the user has left the vehicle. On the other hand, the sunshade device 10 can deploy the sunshade 15 based on the amount of power generated by the solar cell 11. Therefore, even if the deployment of the sunshade 15 becomes necessary due to a change in the weather, the sunshade device 10 can deploy the sunshade 15 on behalf of the user. As a result, user convenience can be improved.

[0037] Furthermore, in the sunshade device 10, the control circuit 13 can control the drive device 14 to retract the sunshade 15 when the vehicle 1 is capable of traveling. As a result, the sunshade device 10 can retract the sunshade 15 when the engine of the vehicle 1 starts, allowing the user (driver) to start driving the vehicle 1 without having to retract the sunshade 15 by hand. As a result, user convenience can be improved.

[0038] The sunshade device 10 further includes a battery 121 capable of storing power, and the drive device 14 deploys the sunshade 15 based on the power stored in the battery 121. As a result, for example, when deploying the sunshade 15 based on the power stored in the auxiliary battery 4, power from the auxiliary battery 4 is consumed. In particular, since the engine is stopped when deploying the sunshade 15, consuming power from the auxiliary battery 4 may result in a low stored power level, making it impossible to start the engine. On the other hand, the sunshade device 10 deploys the sunshade 15 based on the power stored in the battery 121, so power from the auxiliary battery 4 is not consumed. Furthermore, because the sunshade device 10 does not need to consume power from the auxiliary battery 4 when the engine is stopped, it is possible to prevent the battery from running out. As a result, user convenience is improved.

[0039] [effect] As described above, this embodiment includes a solar cell that is provided in a vehicle and is capable of generating electricity based on sunlight, a sensor that can detect the amount of electricity generated by the solar cell, a sunshade that is provided in the vehicle cabin and can be deployed to cover the vehicle window to block sunlight and can be stored in a position corresponding to the edge of the window, a drive unit that can drive the sunshade to deploy and store, and a processing circuit that can control the drive unit to deploy the sunshade when the amount of electricity generated is equal to or greater than a first threshold when the vehicle is not capable of driving, thereby improving user convenience.

[0040] In this embodiment, the processing circuit is capable of controlling the drive device to retract the sunshade when the vehicle is capable of traveling, thereby improving user convenience.

[0041] In this embodiment, a battery capable of storing electricity is further provided, and the drive device is capable of driving the sunshade to unfold based on the electricity stored in the battery, thereby improving convenience for the user.

[0042] [Variation 1] In the above embodiment, whether to deploy the sunshade 15 is determined based on the amount of power generated by the solar cell 11, but this is not limited to this. Instead, for example, whether to deploy the sunshade 15 may be determined based on the amount of power generated by the solar cell 11 and the amount of power stored in the battery 121. A vehicle 1A according to this modified example will be described in detail below.

[0043] 3 shows an example of the configuration of a vehicle 1A. The vehicle 1A is equipped with a sunshade device 10A. The sunshade device 10A is equipped with a power storage device 12A and a control circuit 13A.

[0044] The power storage device 12A has a stored power amount estimation unit 123A. The stored power amount estimation unit 123A is configured to estimate the amount of stored power of the battery 121. The stored power amount estimation unit 123A is configured to supply information on the estimated stored power amount to the control circuit 13A.

[0045] The control circuit 13A has a power storage amount determination unit 134A. The power storage amount determination unit 134A is configured to determine whether the power storage amount of the battery 121 is equal to or greater than a threshold value TH2, based on the power storage amount estimated by the power storage amount estimation unit 123A of the power storage device 12A. The threshold value TH2 is a value that serves as a reference value for the power storage amount to determine whether or not to deploy the sunshade 15.

[0046] Here, the threshold value TH2 corresponds to a specific but not limitative example of a "second threshold value" in an embodiment of the present disclosure.

[0047] 4 shows an example of the operation of the sunshade device 10A. The processes in steps S101 to S106 are the same as those in the above embodiment (FIG. 2).

[0048] In step S103, when the power generation amount determination unit 132 of the control circuit 13A determines that the power generation amount of the solar cell 11 is equal to or greater than the threshold value TH1 ("Y" in step S103), the stored power amount determination unit 134A of the control circuit 13A determines whether the stored power amount of the battery 121 estimated by the stored power amount estimation unit 123A is equal to or greater than the threshold value TH2 (step S113A). When the stored power amount determination unit 134A determines that the stored power amount of the battery 121 is not equal to or greater than the threshold value TH2 ("N" in step S113A), this process ends.

[0049] In step S113A, if the stored power amount determination unit 134A determines that the stored power amount of the battery 121 is equal to or greater than the threshold value TH2 ("Y" in step S113A), the sunshade device 10A unfolds the sunshade 15 (step S104).

[0050] In this way, the sunshade device 10A can determine whether to deploy the sunshade 15 based on the amount of electricity stored in the battery 121. Therefore, the sunshade device 10A can deploy the sunshade 15 after securing sufficient power required to deploy the sunshade 15.

[0051] [Variation 2] In the above embodiment, whether to deploy the sunshade 15 is determined based on the amount of power generated by the solar cell 11, but this is not limited to this. Instead, for example, whether to deploy the sunshade 15 may be determined based on the amount of power generated by the solar cell 11 and the temperature inside the vehicle 1. A vehicle 1B according to this modified example will be described in detail below.

[0052] 5 shows an example of the configuration of a vehicle 1B. The vehicle 1B is equipped with a sunshade device 10B. The sunshade device 10B is equipped with a temperature sensor 16B and a control circuit 13B.

[0053] The temperature sensor 16B is configured to detect the temperature inside the passenger compartment of the vehicle 1B and to supply information about the detected temperature to the control circuit 13B.

[0054] The control circuit 13B has an interior temperature determination unit 135B. The interior temperature determination unit 135B determines whether the temperature inside the interior of the vehicle 1B is equal to or higher than a threshold value TH3, based on the temperature detected by the temperature sensor 16B.

[0055] 6 shows an example of the operation of the sunshade device 10B. The processes in steps S101 to S106 are the same as those in the above embodiment (FIG. 2).

[0056] In step S103, if the power generation amount determination unit 132 of the control circuit 13B determines that the power generation amount of the solar cell 11 is equal to or greater than the threshold value TH1 ("Y" in step S103), the vehicle interior temperature determination unit 135B of the control circuit 13B determines whether the temperature inside the vehicle interior of the vehicle 1 detected by the temperature sensor 16B is equal to or greater than the threshold value TH3 (step S113B). If the vehicle interior temperature determination unit 135B determines that the temperature inside the vehicle interior of the vehicle 1B is not equal to or greater than the threshold value TH3 ("N" in step S113B), this process ends.

[0057] In step S113B, if the vehicle interior temperature determination unit 135B determines that the temperature in the vehicle interior of the vehicle 1B is equal to or higher than the threshold value TH3 ("Y" in step S113B), the sunshade device 10B unfolds the sunshade 15 (step S104).

[0058] In this way, the sunshade device 10B can determine whether to deploy the sunshade 15 based on the temperature inside the cabin of the vehicle 1B. Therefore, the sunshade device 10B can deploy the sunshade 15 when the temperature inside the cabin of the vehicle 1B is high.

[0059] [Variation 3] In the above embodiment, whether the vehicle 1 is in a state where it can run is determined based on information about the switch state of the ignition switch 2, but this is not limited to this. Instead, for example, whether the vehicle 1 is in a state where it can run may be determined based on whether there is an occupant in the vehicle 1. The sunshade device 10C according to this modified example will be described in detail below.

[0060] 7 shows an example of the configuration of a vehicle 1C. In this example, the vehicle 1C includes a human sensor 5C and a sunshade device 10C. The sunshade device 10C includes a control circuit 13C.

[0061] The human presence sensor 5C is, for example, an infrared sensor provided in the driver's seat of the vehicle 1C, and is configured to detect an occupant in the driver's seat and supply the detection result to the control circuit 13C.

[0062] The control circuit 13C has a drivable state determination unit 131C. The drivable state determination unit 131C is configured to determine whether the vehicle 1C is in a drivable state based on information supplied from the human presence sensor 5C. Specifically, the drivable state determination unit 131C determines that the vehicle 1C is in a drivable state when the human presence sensor 5C detects an occupant in the driver's seat, and determines that the vehicle 1C is not in a drivable state when the human presence sensor 5C does not detect an occupant in the driver's seat.

[0063] The sunshade device 10C operates in the same manner as the sunshade device 10 according to the above embodiment (FIG. 2). In step S101, the driveable state determination unit 131C of the control circuit 13C determines whether the vehicle 1C is in a driveable state based on information detected by the human presence sensor 5C. Other operations are the same as those in the above embodiment.

[0064] In this example, the human presence sensor 5C is provided, and whether the vehicle 1C is in a state where it can run is determined based on the detection result of the human presence sensor 5C, but the present invention is not limited to this. Alternatively, for example, an imaging device that captures images of the interior of the vehicle may be provided, and whether the vehicle 1C is in a state where it can run may be determined by determining whether there is an occupant inside the vehicle based on the captured image generated by the imaging device.

[0065] [Other variations] Two or more of these variations may also be combined.

[0066] The present technology has been described above by giving embodiments and some modified examples, but the present technology is not limited to these embodiments and can be modified in various ways.

[0067] For example, in the above embodiment, the vehicle 1 is a vehicle powered by an engine, but is not limited to this. Alternatively, for example, the vehicle may be a vehicle powered by a motor (electric vehicle). In this case, the drivable state determination unit 131 can determine whether the vehicle 1 is in a drivable state based on information about the state of the start switch of the electric vehicle. Alternatively, the vehicle may be a vehicle powered by both an engine and a motor (hybrid vehicle).

[0068] For example, in the above embodiment, the drive device 14 retracts the sunshade 15 using the power supplied from the auxiliary battery 4, but this is not limited to this. Instead, for example, the drive device 14 may retract the sunshade 15 based on the power supplied from the battery 121.

[0069] The effects described in this specification are merely examples and are not limiting, and other effects may also be achieved.
