(Embodiment)
The environmental control system according to the present embodiment is a system for controlling the environment of a room of a mobile body. For example, when a user other than the driver takes a rest or works in the room, the environmental control system provides a space in the room suitable for resting or working.

[Mobile room]
The room of the mobile body will be described with reference to FIG.

Figure 1 is a perspective view showing the room 6 of the mobile unit 5.

The mobile body 5 is, for example, a vehicle such as an automobile. Note that the mobile body 5 is not limited to an automobile, and may be a train or an airplane. The living space 6 is a space provided within the mobile body 5. FIG. 1 shows an example in which the living space 6 of the mobile body 5 is a space on the rear seat side of an automobile.

The living room 6 is provided with multiple seats 7. Users of the living room 6 sit on the seats 7 to rest or perform designated work.

The seat 7 has a seat on which the user sits, a footrest rotatably connected to the seat, a backrest rotatably connected to the seat, and a headrest connected to the backrest. When the user is working, the seat 7 functions as a chair. When the user is taking a rest, the seat 7 may function as a bed, with the footrest, seat, backrest, and headrest arranged in a straight line.

The user is able to take a rest in the living room 6. A rest is an action that the user takes to rest the body and mind. For example, the user may sleep, meditate, etc. during the rest time. The user is also able to take an action other than a rest in the living room 6. Here, an action other than a rest is called a non-rest time. For example, the user may work, study, or perform other tasks during the non-rest time.

An information terminal 10 and an environment generating device 60 are provided in the living room 6.

The information terminal 10 is a user interface that allows the environmental control system 1 to exchange various types of information with the user. The information terminal 10 is, for example, a tablet terminal or a smartphone. The information terminal 10 can be freely carried around within the living room 6, but is not limited to this. The information terminal 10 may be fixed to the top surface of an armrest, or may be attached to the underside of the backrest of the front seat.

The environment generating device 60 is a device that generates an environment within the living room 6. The environment generating device 60 is composed of at least one of a lighting device 61, an audio device 62, a blower 63, and an aroma diffuser 64.

The lighting device 61 is provided, for example, on an armrest and a side pillar. A plurality of lighting devices 61 may be provided in the passenger compartment 6. The lighting device 61 may be provided on the interior roof above the user, or on the rear side of the backrest of the front seat in front of the user.

The acoustic device 62, the blower 63, and the fragrance device 64 are provided, for example, on the upper surface or side surface of the armrest. The acoustic device 62, the blower 63, and the fragrance device 64 may also be provided on the side pillar, the interior roof, or the back side of the backrest of the front seat.

The environmental control system 1 provides a space in the room 6 suitable for the user to rest and not rest by controlling the environment generating device 60 based on information collected by the information terminal 10.

[Environmental control system configuration]
The configuration of an environmental control system 1 according to an embodiment will be described with reference to FIGS.

Figure 2 is a block diagram showing the configuration of an environmental control system 1 according to an embodiment.

The environmental control system 1 includes an information terminal 10, a calculation control unit 50, and an environment generating device 60.

The calculation control unit 50 is communicatively connected to each of the information terminal 10 and the environment generating device 60. For example, the calculation control unit 50 is connected to the environment generating device 60 by a wire and is connected to the information terminal 10 wirelessly, such as via Bluetooth (registered trademark) or WiFi (registered trademark). The calculation control unit 50 may also be connected to the information terminal 10 by a wire.

In FIG. 1, the calculation control unit 50 is provided inside the armrest, but this is not limited thereto. For example, the calculation control unit 50 may be provided in the rear seat or the front seat, or may be provided in the front center panel.

The environment generating device 60 is composed of at least one of a lighting device 61, an audio device 62, a blower 63, and an aroma diffuser 64. Each of the lighting device 61, the audio device 62, the blower 63, and the aroma diffuser 64 is controlled by the calculation control unit 50.

The lighting device 61 emits light to illuminate the living room 6. The lighting device 61 has a dimming function that changes the amount of light. The lighting device 61 changes the light output by receiving a lighting control instruction from the calculation and control unit 50. For example, the lighting device 61 executes dimming control by obtaining a lighting control instruction from the calculation and control unit 50 according to travel time information im and schedule information is, which will be described later. The lighting device 61 provides the user with lighting that helps the user fall asleep, lighting that wakes the user up, or lighting that allows the user to concentrate on work, by changing the luminance (brightness), etc.

The audio device 62 plays music to calm the interior of the living room 6. By receiving sound control instructions from the calculation and control unit 50, the audio device 62 provides the user with music that helps them fall asleep, music that wakes them up, or music that helps them concentrate on their work.

The blower 63 is an air conditioning device provided in the living room 6. The blower 63 generates an air current in the living room 6 by blowing air from an air outlet. The blower 63 adjusts the air quality (e.g., air temperature and humidity) in the living room 6 by taking in air from the outside space. The aroma diffuser 64 is provided in the living room 6, and adjusts the air quality (e.g., scent) in the living room 6 by introducing an aromatic agent into the air blown out from the air outlet. The blower 63 and the aroma diffuser 64 obtain air quality control instructions from the calculation control unit 50, and provide the user with air quality that helps them to fall asleep, air quality that wakes them up, or air quality that allows them to concentrate on their work.

The information terminal 10 is a device that exchanges various types of information with a user. The information terminal 10 has an input unit 11 that accepts operational input from the user, and a display unit 12 that displays various types of information to the user. The input unit 11 and the display unit 12 may be configured as a single component rather than separate components. In this embodiment, the input unit 11 and the display unit 12 are configured as a touch panel.

For example, the input unit 11 accepts information related to the destination of the moving body 5 before the moving body 5 departs. The input unit 11 may also accept information related to the departure point of the moving body 5 as necessary. If the destination of the moving body 5 is changed, the input unit 11 may accept information related to the new destination while the moving body 5 is moving. The input unit 11 outputs the information related to the destination accepted by the user's operational input to the calculation control unit 50.

Figure 3 shows an example of travel time information im, which is information including travel time T1 of a moving object 5.

The calculation control unit 50 calculates travel time information im, which is information including the travel time T1 of the mobile unit 5, based on information about the destination output from the input unit 11, and acquires the travel time information im. The travel time T1 of the mobile unit 5 is determined based on information about the departure point and destination of the mobile unit 5. The information about the departure point and destination of the mobile unit 5 includes traffic information on the route from the departure point to the destination. The traffic information includes information about, for example, congestion, road construction, traffic accidents, etc.

For example, the calculation control unit 50 acquires information on the current location of the mobile unit 5, traffic information on the route from the departure point to the destination, and the travel time T1 of the mobile unit 5 from a car navigation system installed in the mobile unit 5. The calculation control unit 50 may also connect to an external communication network via the information terminal 10 and acquire information required to calculate the travel time T1 from an information server on the communication network.

The traffic information may be current traffic information or future traffic information predicted corresponding to the travel time T1. If the mobile object 5 has traveled between the same departure point and destination in the past, the calculation control unit 50 may obtain the travel time T1 of the mobile object 5 based on the actual travel time included in the travel history information. The travel history information of the mobile object 5 is stored, for example, in an internal memory of the calculation control unit 50.

The input unit 11 also accepts input information for setting the user's schedule information is as user operation input.

The input information for setting the schedule information is includes information regarding the user's breaks and non-breaks. The information regarding breaks includes at least one of the following: the number of breaks, the timing of breaks, and the length of break times. Break times are, for example, times when the user sleeps, meditates, etc. The information regarding non-breaks includes at least one of the following: the number of non-breaks, the timing of non-breaks, and the length of non-break times. Non-break times are times other than break times, and are, for example, times when the user works, studies, or performs other tasks. Non-break times may also include time for hobbies such as reading and games.

The input unit 11 outputs the above input information received through user operation input to the calculation control unit 50.

The calculation control unit 50 calculates the user's schedule information is based on the input information output from the input unit 11, and obtains the schedule information is.

Figure 4 shows an example of schedule information is for a user who uses a room.

The schedule information is is information corresponding to the time from t0 to t1, which is the movement time of the moving object 5.

Figure 4(a) shows an example where a non-break time is set after a break time. Figure 4(b) shows an example where a break time is set after a non-break time. Figure 4(c) shows an example where the start and end of travel time T1 are non-break times, and the time between the start and end is a break time. Figure 4(d) shows an example where the start and end of travel time T1 are break times, and the time between the start and end is a non-break time.

These schedule information is reflect information regarding the number, timing, and duration of each break and non-break. FIG. 4 shows an example in which part of the travel time T1 is break time and the rest is non-break time, but this is not limited to this. For example, the entire travel time T1 may be break time, or the entire travel time T1 may be non-break time.

In this way, the calculation control unit 50 acquires the travel time information im and the schedule information is. The travel time information im and the schedule information is are stored in the internal memory of the calculation control unit 50. The calculation control unit 50 may acquire all of the schedule during the travel time T1 when the moving body 5 departs, or may acquire only a portion of the schedule during the travel time T1 depending on the progress of the schedule.

The calculation control unit 50 causes the display unit 12 to display the travel time information im and schedule information is. The calculation control unit 50 may cause the display unit 12 to display, as the travel time information im, the time until the mobile object 5 arrives at the destination. The calculation control unit 50 may cause the display unit 12 to display, as the schedule information is, the remaining time of a break and the remaining time of a non-break. The display unit 12 displays the travel time information im and schedule information is output from the calculation control unit 50.

The calculation control unit 50 outputs a control instruction signal s1 for controlling the environment generating device 60 based on the travel time information im and the schedule information is. In this embodiment, the calculation control unit 50 controls the environment generating device 60 differently depending on whether the user is in a break time or a non-break time.

During break times, the calculation and control unit 50 provides lighting with a sleep-inducing effect and lighting with a waking-up effect by controlling the lighting device 61 to a constant light or dynamic light. Lighting control may include turning the light off as well as turning it on and off. Control of the lighting device 61 during break times will be described in detail in variant example 1.

During non-break times, the calculation and control unit 50 provides lighting that allows users to concentrate on their work.

Figure 5 shows the relationship between the work surface illuminance and the required illuminance of each surface. In this embodiment, the work surface illuminance is the illuminance of the surface of sheet 7.

The figure shows the relationship between the work surface illuminance and the required illuminance for the surrounding desks, walls, and people's faces. Category I shows the brightness that is just right for the user to work, and Category II shows the minimum brightness required for the user to work. It is desirable for the calculation and control unit 50 to control the lighting device 61 so that the conditions for Category I are met.

For example, if the illuminance of the work surface in room 6 is set to 300 lx (lx: lux) and the illuminance near the wall is set to 220 lx, the user's eyes will not become fatigued easily. In this way, by increasing the illuminance of the work area and lowering the illuminance of the surrounding areas, it becomes possible to concentrate on work during non-break times.

The calculation and control unit 50 may also control the lighting device 61 so that the conditions are at least Category II or higher. For example, the calculation and control unit 50 may control the lighting device 61 so that the minimum value of the sheet surface illuminance, which is the illuminance on the surface of the sheet 7, is always 100 lx or higher, as the minimum brightness.

In this way, the environmental control system 1 controls the environment generating device 60 based on the travel time information im and schedule information is acquired by the calculation control unit 50. This makes it possible to control the environment of the room 6 in accordance with the travel time T1 of the mobile object 5 and the user's schedule. In addition, by setting the schedule information is, which includes rest times and non-rest times, the user can use their time efficiently.

In the above, an example has been shown in which the calculation control unit 50 directly controls the environment generating device 60, but this is not limiting, and the calculation control unit 50 may indirectly control the environment generating device 60. For example, the calculation control unit 50 may transmit a control instruction signal s1 to an ECU (Electronic Control Unit) of the mobile object 5 and control the environment generating device 60 via the ECU.

The environmental control system 1 may also have a notification unit that notifies the user of information regarding breaks and non-breaks. For example, the notification unit may be the display unit 12 of the information terminal 10. In this case, the environmental control system 1 causes the display unit 12 to display information regarding breaks and non-breaks by text or images. The notification unit may also be a speaker of the information terminal 10. In this case, the environmental control system 1 causes the speaker to output information regarding breaks and non-breaks by voice. The notification unit may also be a lighting device 61. In this case, the environmental control system 1 notifies the user of information regarding breaks and non-breaks by adjusting the brightness, color, and blinking of the lighting device 61.

[Adjustment of travel time and schedule information]
In the environmental control system 1, the travel time information im and the schedule information is may be adjusted as follows.

For example, the input unit 11 may accept a change input for changing at least one of the travel time information im and the schedule information is. When the calculation control unit 50 accepts this change input, it changes at least one of the travel time information im and the schedule information is based on the change input. At this time, the calculation control unit 50 may impose restrictions on the input conditions input to the input unit 11. For example, a restriction may be imposed so as not to accept an input that sets the rest time to two hours when the travel time T1 of the moving object 5 is one hour. This change input may be made while the moving object 5 is moving, or before the departure of the moving object 5.

The calculation control unit 50 may change the subsequent break time depending on the time actually taken for the non-break. For example, if there is a break time after the non-break time, the calculation control unit 50 may change the length of the subsequent break time depending on the change in the length of the non-break time. Specifically, if the non-break time is 15 minutes longer than planned, the calculation control unit 50 may reduce the subsequent break time by 15 minutes. The environmental control system 1 may execute these change processes after notifying the user and obtaining confirmation input from the user. Alternatively, the environmental control system 1 may execute these change processes automatically without notifying the user and obtaining confirmation input from the user.

The calculation control unit 50 may also change the schedule information is in response to a change in the travel time information im. For example, the calculation control unit 50 may change the initial time allocation and number of breaks and non-breaks when it is likely to arrive at the destination earlier than planned, or when it is likely to arrive at the destination later than planned.

As a specific example, the calculation control unit 50 acquires a new travel time T2 from the departure point to the destination based on travel time information im that has been changed due to traffic conditions, etc. Then, the calculation control unit 50 calculates the difference Δt (= T2 - T1) between the newly acquired travel time T2 and the original travel time T1 acquired at the time of departure. If the difference Δt is short, there is no need to change the schedule information is, so the calculation control unit 50 judges whether or not to change the schedule information is depending on the value of the difference Δt. The calculation control unit 50 has a threshold value X set in advance for judging whether or not the schedule information is needs to be changed. For example, the threshold value X is set to 3 minutes as the time required to confirm, consider, and input corrections to changes to break and non-break times. The threshold value X may be set appropriately depending on the importance of the event to be held at the destination, etc.

Below, we explain how to change the schedule information is depending on the value of the difference Δt and whether the schedule information is can be changed.

For example, if -X<Δt<+X and a rest period is set after calculating the difference Δt, the calculation control unit 50 changes the length of the most recent rest period for which the difference Δt was calculated by the difference Δt.

For example, if -X<Δt<+X and no rest time has been set after calculating the difference Δt, the calculation control unit 50 changes the length of the most recent non-rest time for which the difference Δt was calculated by the difference Δt.

For example, if Δt≦-X or Δt≧+X, and the difference Δt was calculated during a non-break time, the calculation control unit 50 causes the information terminal 10 to display a notification and a selection instruction to change at least one of the break time and the non-break time after the difference Δt was calculated. The calculation control unit 50 changes at least one of the break time and the non-break time based on the selection instruction received by the information terminal 10.

For example, if Δt≦-X or Δt≧+X, and the difference Δt was calculated during a break, the calculation control unit 50 changes the length of the current break by the difference Δt.

By changing the travel time information im and schedule information is in this way, it is possible to adjust break times and non-break times in response to advancement or delay of arrival.

[An example of the operation of the environmental control system]
Among the operations of the environmental control system 1, the operation when the user takes a rest and then performs a task will be described with reference to Figures 6 and 7. Note that the task shown below is an example of a non-resting task.

Figure 6 is a diagram showing an example of the operation of the environmental control system 1 when a user takes a break and then works. Figure 7 is a diagram showing an example of a screen displayed on the information terminal 10.

Figure 6 shows the operation of the environmental control system 1, which is to display various information on the information terminal 10. Figure 7 (a) to (m) show the screens of the information terminal 10 corresponding to the operations in Figure 6 in chronological order.

The environmental control system 1 causes the information terminal 10 to display a screen for inputting the destination (step S11). When the environmental control system 1 accepts an operational input related to the destination, it calculates the travel time T1 from the current location to the destination and causes the information terminal 10 to display the travel time T1. When calculating the travel time T1, the environmental control system 1 may calculate the travel time T1 based on information related to the departure point and destination and traffic information. When calculating the travel time T1, the environmental control system 1 may calculate the travel time T1 based on the movement history information of the mobile object 5. FIG. 7(a) shows that the travel time T1 to the destination is 70 minutes.

Next, the environmental control system 1 causes the information terminal 10 to display a screen for inputting the action the user is about to take (step S12). For example, as shown in FIG. 7(b), the information terminal 10 displays a screen for allowing the user to select whether to take a break or to work. In this example, the user has selected to take a break.

Next, the environmental control system 1 causes the information terminal 10 to display a screen for accepting input information for setting the schedule information is (step S13). For example, as shown in FIG. 7(c), the information terminal 10 displays a screen for accepting input information for determining the length of the break time. In this example, the break time is set to 30 minutes. In step S13, in addition to the length of the break time, information indicating the number of breaks and the timing of the breaks may be input.

The environmental control system 1 calculates the schedule information is based on the input information and displays the schedule information is on the screen of the information terminal 10 (step S14). The screen in FIG. 7(d) shows that the break time is 30 minutes from now.

During the break, the environmental control system 1 displays the remaining break time on the screen of the information terminal 10 (step S15). The screen in FIG. 7(e) shows that there are 15 minutes of break time remaining. The remaining break time is not limited to text information, and may be displayed visually by an indicator. As shown in FIG. 7(e), the environmental control system 1 may display on the information terminal 10 a screen for confirming whether or not to stop the break midway or whether or not to extend the break time. The environmental control system 1 may also display on the screen of the information terminal 10 the time remaining until arrival at the destination.

When the break time ends, the environmental control system 1 causes the information terminal 10 to display a screen indicating that the break time has ended (step S16). Furthermore, when the break time ends, the environmental control system 1 causes the screen of the information terminal 10 to display the time remaining until arrival at the destination (step S17). The screen in FIG. 7(f) shows that the break time has ended, and also shows that there are 25 minutes remaining until arrival. The time remaining until arrival is not limited to being displayed as text information, and may be displayed visually by an indicator.

Next, the environmental control system 1 causes the information terminal 10 to display a screen for inputting the action the user is about to take (step S18). For example, as shown in FIG. 7(f), the information terminal 10 displays a screen for allowing the user to select whether to take a break or to work. In this example, the user has selected to work.

Next, the environmental control system 1 causes the information terminal 10 to display a screen for accepting input information for setting the schedule information is (step S19). For example, as shown in FIG. 7(g), the information terminal 10 displays a screen for accepting input information for determining the length of the work time. In this example, the work time is set to 15 minutes. In step S19, in addition to the length of the work time, information indicating the number of tasks and the timing of the tasks may be input. Note that if all schedules for the travel time T1 have been set at the time of departure, steps S18 and S19 do not need to be executed.

The environmental control system 1 calculates the schedule information is based on the input information and displays the schedule information is on the screen of the information terminal 10 (step S20). (h) of FIG. 7 shows that the work time is 15 minutes from now.

During the work time, the environmental control system 1 displays the remaining work time on the screen of the information terminal 10 (step S21). The screen in FIG. 7(i) shows that there are 5 minutes of work time remaining. The remaining work time is not limited to text information, and may be displayed visually by an indicator. As shown in FIG. 7(i), the environmental control system 1 may display on the information terminal 10 a screen for confirming whether or not to stop the work midway or whether or not to extend the work time. The environmental control system 1 may also display on the screen of the information terminal 10 the time remaining to reach the destination. FIG. 7(i) shows an example in which the user extends the work.

The environmental control system 1 again causes the information terminal 10 to display a screen for accepting input information for setting the schedule information is (step S22). For example, as shown in FIG. 7(j), the information terminal 10 displays a screen for accepting input information for determining the extension time of the work. In this example, the extension time of the work is set to 10 minutes.

During the extension of the work time, the environmental control system 1 displays the remaining work time on the screen of the information terminal 10 (step S23). FIG. 7(k) shows that there are 10 minutes of work time remaining. As shown in FIG. 7(k), the environmental control system 1 may display on the information terminal 10 a screen for confirming whether or not to stop the work midway or whether or not to further extend the work time. The environmental control system 1 may also display on the screen of the information terminal 10 the time remaining to reach the destination.

When the work time ends, the environmental control system 1 causes the information terminal 10 to display a screen indicating that the work time has ended (step S24). In addition, when the work time ends, the environmental control system 1 causes the information terminal 10 to display the time remaining until arrival at the destination (step S25). The screen in FIG. 7(l) shows that the work time has ended, and also shows that there are three minutes remaining until arrival.

When the moving body 5 arrives at the destination, the environmental control system 1 causes the information terminal 10 to display a screen indicating that the moving body 5 has arrived at the destination (step S26). The screen in FIG. 7 (m) indicates that the moving body 5 has arrived at the destination.

By executing these steps, the environmental control system 1 can control the environment of the room 6 according to the travel time T1 of the mobile object 5 and the user's schedule.

[Another example of the operation of the environmental control system]
Among the operations of the environmental control system 1, the operation when a user works and then takes a rest will be described with reference to FIGS. 8 and 9. FIG.

Figure 8 is a diagram showing an example of the operation of the environmental control system 1 when a user works and takes a break in sequence. Figure 9 is a diagram showing an example of a screen displayed on the information terminal 10.

Figure 8 shows the operation of the environmental control system 1, which is to display various information on the information terminal 10. Figure 9 (a) to (j) show the screens of the information terminal 10 corresponding to the operations in Figure 8 in chronological order.

The environmental control system 1 causes the information terminal 10 to display a screen for inputting the destination (step S31). When the environmental control system 1 accepts an operational input related to the destination, it calculates the travel time T1 from the current location to the destination and causes the information terminal 10 to display the travel time T1. When calculating the travel time T1, the environmental control system 1 may calculate the travel time T1 based on information related to the departure point and destination and traffic information. When calculating the travel time T1, the environmental control system 1 may calculate the travel time T1 based on movement history information of the mobile object 5. FIG. 9(a) shows that the travel time T1 to the destination is 70 minutes.

Next, the environmental control system 1 causes the information terminal 10 to display a screen for inputting the action the user is about to take (step S32). For example, as shown in FIG. 9(b), the information terminal 10 displays a screen for allowing the user to select whether to take a break or to work. In this example, the user has selected to work.

Next, the environmental control system 1 causes the information terminal 10 to display a screen for accepting input information for setting the schedule information is (step S33). For example, as shown in FIG. 9(c), the information terminal 10 displays a screen for accepting input information for determining the length of the work time. In this example, the work time is set to 30 minutes. In step S33, in addition to the length of the work time, information indicating the number of tasks and the timing of the tasks may be input.

The environmental control system 1 calculates the schedule information is based on the input information and displays the schedule information is on the screen of the information terminal 10 (step S34). The screen in FIG. 9(d) shows that the work time is 30 minutes from now.

During the work time, the environmental control system 1 displays the remaining work time on the screen of the information terminal 10 (step S35). The screen in FIG. 9(e) shows that there are 15 minutes of work time remaining. As shown in FIG. 9(e), the environmental control system 1 may also display on the information terminal 10 a screen for confirming whether or not to stop the work midway or whether or not to extend the work time. The environmental control system 1 may also display on the screen of the information terminal 10 the time remaining to reach the destination.

When the work time ends, the environmental control system 1 causes the information terminal 10 to display a screen indicating that the work time has ended (step S36). In addition, when the work time ends, the environmental control system 1 causes the information terminal 10 to display the time remaining until arrival at the destination (step S37). The screen in FIG. 9(f) shows that the work time has ended, and also shows that there are 40 minutes remaining until arrival.

Next, the environmental control system 1 causes the information terminal 10 to display a screen for inputting the action the user is about to take (step S38). For example, as shown in FIG. 9(f), the information terminal 10 displays a screen for allowing the user to select whether to take a break or to work. In this example, the user has selected to take a break.

Next, the environmental control system 1 causes the information terminal 10 to display a screen for accepting input information for setting the schedule information is (step S39). For example, the information terminal 10 displays a screen for accepting input information for determining the length of the break time, as shown in FIG. 9 (g). In this example, the break time is set to 40 minutes. In step S39, in addition to the length of the break time, information indicating the number of breaks and the timing of the breaks may be input. Note that if all schedules for the travel time T1 have been set at the time of departure, steps S38 and S39 do not need to be executed.

The environmental control system 1 calculates the schedule information is based on the input information and displays the schedule information is on the screen of the information terminal 10 (step S40). (h) of FIG. 9 shows that the break time is 40 minutes from now.

During the break, the environmental control system 1 displays the remaining time of the break on the screen of the information terminal 10 (step S41). The screen in FIG. 9(i) shows that there are 5 minutes of the break time remaining. As shown in FIG. 9(i), the environmental control system 1 may also display on the information terminal 10 a screen for confirming whether or not to end the break midway. The environmental control system 1 may also display on the screen of the information terminal 10 the time remaining until arrival at the destination.

When the break time ends, the environmental control system 1 causes the information terminal 10 to display a screen indicating that the break time has ended (step S42). When the mobile object 5 arrives at the destination, the environmental control system 1 causes the information terminal 10 to display a screen indicating that the destination has been reached (step S43). The screen in FIG. 9 (j) indicates that the break time has ended, and also indicates that the mobile object 5 has arrived at the destination.

By executing these steps, the environmental control system 1 can control the environment of the room 6 according to the travel time T1 of the mobile object 5 and the user's schedule.

(First Modification of the Embodiment)
[Environmental control system configuration]
An environmental control system 1A according to a first modified example of the embodiment will be described. In this example, the control of the lighting device 61 in a case where a user uses the living room 6 as a nap room will be described. In this embodiment, a nap means taking a short nap, and specifically means a short sleep with a rest time of less than 30 minutes.

Figure 10 is a block diagram showing the configuration of an environmental control system 1A according to the first variation of the embodiment.

The environmental control system 1A of the first modification includes an information terminal 10, an arithmetic and control unit 50, and an environment generating device 60, similar to the first embodiment. In the first modification, the operation of the lighting device 61 of the environment generating device 60 will be described.

The environmental control system 1A illuminates the surface of the seat 7 on which the user sits based on the break time in the schedule information is, and executes a lighting mode that puts the user to sleep at the start of the break time, a lighting mode that puts the user to a nap, a lighting mode that wakes up the sleeping user at the end of the break time, and the like. In other words, by executing each lighting mode, the environmental control system 1A provides an environment that supports the user's falling asleep and the awakening of a user who has fallen asleep.

The break time has a constant lighting section, a first lighting control section, and a second lighting control section. The first lighting control section, the constant lighting section, and the second lighting control section are arranged in this chronological order.

The constant lighting section is a section in which the light output of the lighting device 61 is approximately constant, and is a section in which the user takes a nap. The length of the constant lighting section is 20% or more of the length of the rest period. The maximum value of the sheet surface illuminance, which is the illuminance of the surface of the sheet 7 in the constant lighting section, is always less than 50 lx. The maximum value of the sheet surface illuminance may also be always less than 40 lx, always less than 30 lx, always less than 20 lx, or always less than 10 lx.

Here, a substantially constant light output means that, for example, the brightness on the sheet surface does not change over approximately 60 seconds, or is constant enough that the user does not notice the change in brightness. The change in brightness is, for example, within ±10 lx over 60 seconds. A change in brightness of this magnitude is unlikely to disturb the user's sleep.

Here, the seat surface illuminance is the illuminance on the surface of the seat 7 when the lighting device 61 is turned on. In particular, the maximum value of the seat surface illuminance is always less than 50 lx in the head area. The seat surface illuminance in the head area is the illuminance on the surface of the seat 7 where the head of the user is placed when seated on the seat 7. In this embodiment, the seat surface illuminance in the head area is considered to be equivalent to the illuminance of the head of a user seated on the seat 7, that is, the facial illuminance.

The first lighting control section is a section preceding the constant lighting section, which is a section for encouraging the user to fall asleep. The first lighting control section includes a section in which the seat surface illuminance, which is the illuminance on the surface of the seat 7, is increased by 0.03 lx or more for 5 seconds, and a section in which the seat surface illuminance is decreased by 0.03 lx or more for 5 seconds. In other words, during the first lighting control section, the light fluctuates periodically, causing the indoor space to become brighter and darker.

The average illuminance of the first lighting control section is at least 1.5 times that of the constant lighting section. In other words, the section where the user takes a nap (constant lighting section) is darker than the section where the user is encouraged to fall asleep (first lighting control section), so room 6 becomes an appropriate sleeping environment for the user.

The second lighting control section is a section that follows the constant lighting section and is a section that encourages the user to wake up. The second lighting control section also includes a section in which the seat surface illuminance is increased by 10 lx or more for 10 seconds. The length of the second lighting control section is 35% or less of the length of the break time.

In addition, the end point of the second lighting control period and the end point of the break time approximately coincide with each other. In other words, the second lighting control period for waking up the user is placed in the latter half of the break time, so that the user can get an efficient rest.

The sum of the length of the first lighting control section and the length of the constant lighting section is longer than the length of the second lighting control section. In this case, the first lighting control section, which is a section that encourages the user to fall asleep, and the constant lighting section, which is a section in which the user naps, can ensure a long nap time for the user. Therefore, even if the nap time is short, the user can take as long a nap time as possible, and can therefore get some rest.

The length of the constant lighting section is longer than the length of the first lighting control section. Because the constant lighting section is the period during which the user takes a nap, the calculation and control unit 50 sets the constant lighting section to be longer than the first lighting control section. This allows the user to take as long a nap time as possible, even if the break time is short, and thus allows the user to take a rest.

The calculation control unit 50 acquires the schedule information is from the input unit 11, generates lighting control instructions based on the acquired schedule information, and outputs the generated lighting control instructions to the lighting device 61. Specifically, the calculation control unit 50 changes the length of the fixed lighting section according to the length of the break time indicated in the acquired schedule information, and controls the lighting device 61 by outputting lighting control instructions according to the changed fixed lighting section to the lighting device 61.

The calculation control unit 50 also controls the lighting device 61 by outputting a lighting control instruction corresponding to the first lighting control section to the lighting device 61. Specifically, the calculation control unit 50 controls the lighting device 61 by changing the length of the first lighting control section according to the length of the break time indicated in the acquired schedule information, and outputting a lighting control instruction corresponding to the changed length of the first lighting control section to the lighting device 61.

The calculation control unit 50 also controls the lighting device 61 by outputting a lighting control instruction corresponding to the second lighting control section to the lighting device 61. Specifically, the calculation control unit 50 controls the lighting device 61 by changing the length of the second lighting control section according to the length of the break time indicated in the acquired schedule information, and outputting a lighting control instruction corresponding to the changed length of the second lighting control section to the lighting device 61.

In addition, when the break time is less than 30 minutes, the calculation control unit 50 changes the length of the first lighting control period so that the first lighting control period is less than 5 minutes, and changes the length of the second lighting control period so that the second lighting control period is less than 5 minutes. The calculation control unit 50 controls the lighting device 61 by outputting a lighting control instruction to the lighting device 61 according to the changed length of the first lighting control period and the length of the second lighting control period.

In addition, when the break time is 30 minutes or more, the calculation control unit 50 changes the length of the first lighting control period so that the first lighting control period is 5 minutes or more, and changes the length of the second lighting control period so that the second lighting control period is 5 minutes or more. The calculation control unit 50 controls the lighting device 61 by outputting a lighting control instruction to the lighting device 61 according to the changed length of the first lighting control period and the length of the second lighting control period.

In addition, the calculation control unit 50 may change the length of the first lighting control section so that the first lighting control section is less than 5 minutes when the break time is less than 30 minutes, and may change the length of the first lighting control section so that the first lighting control section is more than 5 minutes when the break time is 30 minutes or more. In this case, the change in the first lighting control section when the first lighting control section is less than 5 minutes and the change in the first lighting control section when the first lighting control section is 5 minutes or more may be a change in which the calculation control unit 50 expands or contracts the first lighting control section in time in the time axis direction according to the length of the break time. In this way, when the calculation control unit 50 expands or contracts the first lighting control section in time when the break time is less than 30 minutes or more than 30 minutes, the first lighting control section can be set finely, so that there is continuity in the change in brightness and abrupt changes in brightness are suppressed. This makes it possible to suppress discomfort when the user wakes up.

In addition, the calculation control unit 50 may change the length of the second lighting control section so that the second lighting control section is less than 5 minutes when the break time is less than 30 minutes, and may change the length of the second lighting control section so that the second lighting control section is 5 minutes or more when the break time is 30 minutes or more. In this case, the change in the second lighting control section when the second lighting control section is less than 5 minutes and the change in the second lighting control section when the second lighting control section is 5 minutes or more may be changes in which the second lighting control section is expanded or contracted in time along the time axis. In this way, when the break time is less than 30 minutes or the break time is 30 minutes or more, the calculation control unit 50 expands or contracts the second lighting control section in time, so that there is continuity in the change in brightness and abrupt changes in brightness are suppressed. This makes it possible to suppress discomfort when the user wakes up.

Furthermore, the change in the second lighting control section when the second lighting control section is less than 5 minutes may not have a relationship, such as temporal expansion or contraction, with the change in the second lighting control section when the second lighting control section is 5 minutes or more. In this way, different lighting controls may be performed in the second lighting control section when the second lighting control section is less than 5 minutes and when it is 5 minutes or more. Since different users take naps in different ways, by changing the method of waking the user, the discomfort felt by the user when waking can be reduced.

The calculation control unit 50 may also turn off the driving of the lighting device 61 during either the first lighting control period or the second lighting control period. For example, if the rest period is too short, one of the first lighting control period or the second lighting control period may be omitted to ensure that the user has time to nap.

[Regarding the first lighting control section]
The lighting device 61 may control the lighting in a constant cycle in the first lighting control section. That is, the lighting device 61 may change the light output in a pulsating manner by alternating between large and small values in the first lighting control section by acquiring a lighting control instruction from the calculation control unit 50. In this case, in the first lighting control section, the light flickering is periodically repeated on the seat surface, such that the indoor space becomes brighter and darker. The length of the first lighting control section may be an approximate integer multiple of the constant cycle.

Here, Figs. 11A to 11E show examples of brightness when lighting is controlled at a constant cycle in the first lighting control section. Figs. 11A to 11E show, for example, sheet surface illuminance.

First, FIG. 11A is a diagram showing a case where light fluctuates periodically when the first lighting control period is less than 5 minutes. As shown in FIG. 11A, when the first lighting control period is short, such as less than 5 minutes, the lighting device 61 may illuminate the sheet surface so that it repeatedly becomes brighter and darker. FIG. 11A shows an example of light fluctuating for 5 periods, with each period being 40 seconds.

Next, FIG. 11B is a diagram showing a case where light fluctuates periodically when the first lighting control period is 5 minutes or longer. As shown in FIG. 11B, when the first lighting control period is long, such as 5 minutes or longer, the lighting device 61 may illuminate the sheet surface so that it repeatedly becomes brighter and darker. FIG. 11B shows an example of light fluctuating for 23 periods, with each period being 40 seconds.

Next, FIG. 11C is another diagram showing a case where light fluctuates periodically when the first lighting control period is less than 5 minutes. As shown in FIG. 11C, when the first lighting control period is short, such as less than 5 minutes, the lighting device 61 may illuminate the sheet surface so that the width of the light fluctuates gradually decreases over time, with the sheet surface repeatedly becoming brighter and darker. FIG. 11C shows an example of light fluctuating for 5 periods, with each period being 40 seconds.

Next, FIG. 11D is another diagram showing a case where light fluctuates periodically when the first lighting control period is 5 minutes or longer. As shown in FIG. 11D, when the first lighting control period is long, such as 5 minutes or longer, the lighting device 61 may illuminate the sheet surface so that the width of the light fluctuates gradually decreases over time, with the sheet surface repeatedly becoming brighter and darker. FIG. 11D shows an example of 23 cycles of light fluctuating, with each cycle lasting 40 seconds.

When lighting is used that gradually reduces the fluctuation width, as shown in Figures 11C and 11D, the user's eyes become more sensitive to brightness when staying in a dark place such as inside a room 6. Even if the user adapts to the dark, the user will not perceive the fluctuation as being too bright, and will be less likely to be disturbed from falling asleep.

Next, FIG. 11E is yet another diagram showing a case where light fluctuates periodically when the first lighting control period is 5 minutes or longer. As shown in FIG. 11E, when the first lighting control period is long, such as 5 minutes or longer, the lighting device 61 may illuminate the sheet surface so that it repeatedly becomes brighter and darker. As shown in FIG. 11E, the time per cycle may be longer than in FIG. 11A to FIG. 11D. Also, although not shown, the time per cycle may be shorter than in FIG. 11A to FIG. 11D. FIG. 11E illustrates an example of light fluctuating for 5 cycles, with each cycle being 180 seconds.

Note that Figs. 11A to 11E are examples of the first lighting control period, and the first lighting control period is not limited to Figs. 11A to 11E. Furthermore, the time per cycle and the number of cycles are not limited to those in this embodiment.

[Regarding the second lighting control section]
Here, the sheet surface illuminance in the second illumination control section will be illustrated in FIGS. 12A to 12F.

The second lighting control intervals in Figures 12A to 12C, 12E, and 12F are longer than the second lighting control interval in Figure 12D, and Figure 12D is an example of a case where the second lighting control interval is shorter. Note that the lighting control in Figures 12A to 12F is merely an example, and environmental control system 1A is not limited to Figures 12A to 12F.

First, FIG. 12A is a diagram showing the sheet surface illuminance during the second lighting control period when the second lighting control period is long. As shown in FIG. 12A, when the second lighting control period is long, the lighting device 61 illuminates so as to increase the sheet surface illuminance over time.

Next, FIG. 12B is another diagram showing the sheet surface illuminance in the second lighting control section when the length of the second lighting control section is medium. As shown in FIG. 12B, when the length of the second lighting control section is medium, the lighting device 61 illuminates so as to increase the sheet surface illuminance at a steeper rate over time than in FIG. 12A.

Next, FIG. 12C is yet another diagram showing the sheet surface illuminance during the second lighting control period when the second lighting control period is short. As shown in FIG. 12C, when the second lighting control period is short, the lighting device 61 increases the sheet surface illuminance over time at an even steeper rate than in FIG. 12B.

Next, FIG. 12D is yet another diagram showing the sheet surface illuminance during the second lighting control period when the second lighting control period is very short. As shown in FIG. 12D, when the second lighting control period is very short, the lighting device 61 illuminates so as to increase the sheet surface illuminance at an even steeper rate over time than in FIG. 12C.

Next, FIG. 12E is another diagram showing the sheet surface illuminance in the second lighting control section when the length of the second lighting control section is medium. As shown in FIG. 12E, the second lighting control section may have a 2-1 section in which the sheet surface illuminance is increased very gradually, and a 2-2 section in which the sheet surface illuminance is increased at a steeper rate than in the 2-1 section. In this case, the lighting device 61 provides illumination, but in the 2-1 section, the sheet surface illuminance is very low, meaning the sheet surface is dark. Also, in the 2-2 section, the sheet surface illuminance increases suddenly and becomes bright.

Next, FIG. 12F is another diagram showing the sheet surface illuminance in the second lighting control section when the second lighting control section is long. As shown in FIG. 12F, the second lighting control section may have a 2-1 section in which the sheet surface illuminance is increased gradually, and a 2-2 section in which the sheet surface illuminance is increased more rapidly than in the 2-1 section. In this case, in the 2-1 section, the sheet surface illuminance is low, i.e., the sheet surface is dim. In the 2-2 section, the sheet surface illuminance increases suddenly and becomes bright.

In the cases shown in Figures 12A to 12D, if the user's nap time is short, the user may want to secure as much nap time as possible. In this case, even if a lighting control period like that of Figure 12A is set, the user may select lighting control with a shorter lighting control period like that of Figures 12B and 12C, etc.

In addition, in Figures 12E and 12F, by setting the second lighting control period to be long and having the lighting device 61 irradiate light so that the illuminance in the head area is low, it is expected that the user will have a light sleep so as not to wake up. And by making the illuminance in the head area brighter in a short time after the user's sleep becomes light, it is possible to reduce discomfort when the user wakes up. Therefore, when the user is in a deep sleep, the seat surface illuminance suddenly becomes brighter, which reduces the likelihood of the user feeling more uncomfortable.

[Operation of the Environmental Control System According to Modification 1]
The operation of the environmental control system 1A according to the first modification of the embodiment will be described.

Figure 13 is a diagram showing an example of the operation of the environmental control system 1A according to the first variation of the embodiment.

First, the calculation control unit 50 acquires the break time (S111).

Next, the calculation control unit 50 sets a first lighting control section, which is a section in which the user is encouraged to fall asleep, a constant lighting section, which is a section in which the user takes a nap, and a second lighting control section, which is a section in which the user is encouraged to wake up (S112).

For example, the calculation control unit 50 sets, i.e., changes, the length of the first lighting control section, the length of the constant lighting section, and the length of the second lighting control section according to the break time. Specifically, the calculation control unit 50 sets the average illuminance of the first lighting control section to 1.5 times or more the average illuminance of the constant lighting section. The calculation control unit 50 also sets the length of the constant lighting section to 20% or more of the length of the break time. The calculation control unit 50 also sets the length of the second lighting control section to 35% or less of the length of the break time. The calculation control unit 50 also sets the length of the constant lighting section to be longer than the length of the first lighting control section. The calculation control unit 50 also sets the sum of the length of the first lighting control section and the length of the constant lighting section to be longer than the length of the second lighting control section.

The calculation and control unit 50 also sets the sheet surface illuminance for the first lighting control section, the sheet surface illuminance for the constant lighting section, and the sheet surface illuminance for the second lighting control section. Specifically, in the first lighting control section, the calculation and control unit 50 sets a section in which the sheet surface illuminance is increased by 0.03 lx or more for 5 seconds, and a section in which the sheet surface illuminance is decreased by 0.03 lx or more for 5 seconds. The calculation and control unit 50 also sets the maximum value of the sheet surface illuminance in the constant lighting section to always be less than 50 lx. The calculation and control unit 50 also sets a section in which the sheet surface illuminance is increased by 10 lx or more for 10 seconds in the second lighting control section.

In this way, the calculation control unit 50 outputs lighting control instructions to the lighting device 61 for each of the set first lighting control period, constant lighting period, and second lighting control period in chronological order.

Next, when the lighting device 61 acquires a lighting control instruction corresponding to the first lighting control section, the lighting device 61 turns on the lighting with lighting control corresponding to the lighting control instruction during the first lighting control section (S113). The first lighting control section includes a section in which the seat surface illuminance is increased by 0.03 lx or more for 5 seconds, and a section in which the seat surface illuminance is decreased by 0.03 lx or more for 5 seconds, making it easier for the user to fall asleep.

Next, when the lighting device 61 acquires a lighting control instruction corresponding to the constant lighting section, the lighting device 61 turns on the lighting in the constant lighting section with lighting control corresponding to the lighting control instruction (S114). In the constant lighting section, the maximum seat surface illuminance is always kept below 50 lx, allowing the user to take a nap in a dim environment.

Next, when the lighting device 61 acquires a lighting control instruction corresponding to the second lighting control section, the lighting device 61 turns on the lighting control corresponding to the lighting control instruction during the second lighting control section (S115). During the second lighting control section, the seat surface illuminance is increased by 10 lx or more for 10 seconds, allowing the user to get used to the light. This allows the user to wake up without feeling too much discomfort.

(Second Modification of the Embodiment)
The configuration of an environmental control system 1B according to the second modification of the embodiment will be described.

Figure 14 is a block diagram showing the configuration of an environmental control system 1B according to the second variation of the embodiment.

The environmental control system 1B of the second modification includes an information terminal 10 and an arithmetic control unit 50. In other words, the environmental control system 1B of the second modification is composed of the information terminal 10 and the arithmetic control unit 50, and the environment generating device 60 is not included in the environmental control system 1B. The environment generating device 60 in the second modification is controlled based on the control instruction signal s1 output from the environmental control system 1B.

The environmental control system 1B of the second modification also controls the environment generating device 60 based on the travel time information im and schedule information is acquired by the calculation control unit 50. This makes it possible to control the environment of the living room 6 according to the travel time T1 of the moving object 5 and the user's schedule.

(Third Modification of the Embodiment)
The configuration of an environmental control system 1C according to the third modified embodiment will be described.

Figure 15 is a block diagram showing the configuration of an environmental control system 1C according to the third variation of the embodiment.

The environmental control system 1C of the modified example 3 includes an information terminal 10 and an environment generating device 60. The calculation control unit 50 is provided inside the information terminal 10. In other words, the environmental control system 1C of the modified example 3 is composed of the information terminal 10 and the environment generating device 60, and the information terminal 10 has the functions of the calculation control unit 50. The environment generating device 60 in the modified example 3 is controlled based on a control instruction signal s1 output from the calculation control unit 50 of the information terminal 10. Note that the environment generating device 60 may be controlled based on a control instruction signal output from the calculation control unit 50 of the information terminal 10 via the ECU.

The environmental control system 1C of the third modification also controls the environment generating device 60 based on the travel time information im and schedule information is acquired by the calculation control unit 50. This makes it possible to control the environment of the living room 6 according to the travel time T1 of the moving object 5 and the user's schedule.

(summary)
The environmental control system 1 according to this embodiment is an environmental control system that controls the environment of a room 6 of a mobile object 5.
