Further, the seat-side communication unit 24 may be configured to perform wired communication using, for example, USB.

<About the configuration of the air conditioning unit 22>
As shown in FIG. 5, the air conditioning unit 22 includes a compressor 221, a condenser 222, a first blower 223, a decompression unit 224, an evaporator 225, a second blower 226, and a heating device 227.

  The compressor 221 is an electric compressor that is driven by a DC voltage supplied from an in-vehicle battery, and compresses the refrigerant to raise the refrigerant temperature. The compressor 221 is also referred to as a compressor. The refrigerant compressed by the compressor 221 is supplied to the condenser 222. Air is blown to the condenser 222 by the first blower 223. The condenser 222 corresponds to a condenser. The condenser 222 radiates the heat of the refrigerant to the blown air. The refrigerant radiated by the condenser 222 is supplied to the decompression unit 224. In the decompression unit 224, the refrigerant is decompressed by a fixed throttle. The refrigerant decompressed by the decompression unit 224 is provided to the evaporator 225.

  In the evaporator 225, the refrigerant cools the air blown by the second blower 226. Thus, the air is cooled and supplied to the blowing duct (for example, the first duct 14). The refrigerant cooled by the evaporator 225 is provided to the compressor 221. Thus, the compressor 221, the condenser 222, the decompression unit 224, and the evaporator 225 provide a refrigeration cycle.

  The heating device 227 is an electric heater including a PTC heater, a hot wire heater, and the like, and heats air blown by the second blower 226. Thereby, air turns into warm air and is supplied toward the blowing duct. The condenser 222 can also be used as the heating device 227 because the refrigerant that has been compressed by the compressor 221 and supplied with a high temperature is supplied.

  The second blower 226 sucks the air in front of the lower portion of the seat 1 through the suction duct, blows the air toward the evaporator 225 and the heating device 227, and blows out the air that has passed through the evaporator 225 and the heating device 227. Supply duct. Note that the air conditioning unit 22 blows air from the seat outlet through the blowing duct while the refrigeration cycle apparatus and the heating device 227 are turned off during air blowing without cooling or heating.

  The air conditioning unit 22 blows conditioned air from the seat outlet toward the seated person seated on the seat 1, thereby forming a flow of air-conditioned air that wraps around the seated person seated on the seat 1. . The range of the flow of conditioned air generated for each sheet 1 is referred to as an enclosed conditioned space 200 in this specification. The enclosed air-conditioned space 200 is formed for each sheet 1.

  Under the control of the seat air conditioning ECU 21, the air conditioning unit 22 adjusts the temperature of the conditioned air blown from the seat outlet and the amount of blown air so that the temperature of the enclosed conditioned space 200 is maintained at the set temperature. The set temperature itself is determined by, for example, a user instruction operation or a user state. Therefore, the set temperature can be different for each sheet 1. Accordingly, the temperature of the enclosed air-conditioned space 200 of each sheet 1 can be different for each sheet 1. The air conditioning control is preferably performed by feedback control between the temperature of the enclosed air-conditioned space 200 detected by a temperature sensor (not shown) and the set temperature. As described above, the seat 1 and the air conditioning unit 22 act so as to wrap the seated person with the conditioned air.

  Further, as shown in FIG. 3, each seat 1 is provided with a suction port 19 through which air can be sucked from the feet of the seated person. The air suction from the suction port 19 restricts the enclosed air-conditioned space 200, which is the flow of conditioned air for each seat, from reaching a seated person seated on another seat 1.

<Configuration of wearable device 3>
The wearable device 3 is, for example, a wristwatch type or wristband type information processing terminal that is worn on the wrist of the user and measures the biological information of the user. As shown in FIG. 6, the wearable device 3 includes a wearable control unit 31, a biosensor 32, a wearable HMI 33, a wearable communication unit 34, and a camera 35. The wearable device 3 corresponds to a user device.

  The wearable device 3 may be a glasses-type information processing terminal worn on the user's face, or may be a ring-type device worn on the user's finger. In addition, various configurations can be adopted as the wearable device 3, such as a type of apparatus that is used by being worn on a shirt or the like. The user here is a person using the wearable device 3. The user is also a person who can be a seated person of the seat 1.

  The wearable control unit 31 controls the operations of the biosensor 32, the wearable HMI 33, the wearable communication unit 34, and the camera 35, and executes various applications. The wearable control unit 31 is configured using a computer including a CPU 311, a RAM 312, and a flash memory 313. The application referred to here includes an application provided from the outside by download or the like and installed in the wearable device 3. The function of the wearable control unit 31 will be described later.

  The biological sensor 32 is a sensor that measures biological information such as a user's pulse (in other words, heartbeat) and body temperature. For example, the biosensor 32 is a pulse wave sensor that sequentially detects a pulse wave signal indicating a change in blood vessel volume in accordance with a user's pulse. Here, the biosensor 32 as a pulse wave sensor is a photoelectric pulse wave sensor using a light absorption characteristic of a blood component as an example here, but as another aspect, a pulse wave signal is generated by passing a weak current from an electrode. It may be a bioimpedance-type pulse wave sensor that detects the above. Further, in the present embodiment, the case where the wearable device 3 is a wristwatch type is taken as an example, so it is preferable to use a reflective pulse wave sensor rather than a pulse wave transmission type among photoelectric pulse wave sensors.

  The detection result of the biometric sensor 32, that is, the biometric information of the user is sequentially provided to the wearable control unit 31. The biosensor 32 may be configured to detect biometric information other than information related to the pulse. For example, the biosensor 32 may be configured to detect body temperature, blood pressure, sweat rate, and the like.

  The wearable HMI 33 includes a display unit 331 that displays a video signal (in other words, an image) input from the wearable control unit 31, and an input device 332 for a user to input an instruction. The display unit 331 is realized using, for example, a liquid crystal display or an organic EL display. The input device 332 is realized using a touch panel, a hardware switch, or the like.

  The wearable communication unit 34 is a communication module for performing short-range wireless communication. The wearable communication unit 34 provides a function for the wearable device 3 to wirelessly communicate with the seat side communication unit 24. The wearable communication unit 34 may have a function of performing Internet communication. The wearable communication unit 34 may be configured to be able to communicate with the seat side communication unit 24 via a server or the like. The wearable communication unit 34 may be configured to perform wired communication with the seat-side communication unit 24 via a communication cable such as a USB. The wearable communication unit 34 corresponds to the user side communication unit.

  Moreover, in this embodiment, although the wearable device 3 and the sheet | seat air conditioner 2 directly implement short-distance wireless communication as an example, it is not restricted to this. Communication between the wearable device 3 and the seat air conditioner 2 may include a portable terminal 4 carried by the user. Specifically, the wearable device 3 communicates with the portable terminal 4 and the portable terminal 4 communicates with the seat air conditioning ECU 21 so that the wearable device 3 cooperates with the seat air conditioner 2 via the portable terminal 4. It may be configured.

  The camera 35 is a CCD camera, for example. The camera 35 is used for reading a two-dimensional code including information for establishing a communication connection between the wearable device 3 and the seat air conditioner 2, for example. In the configuration in which the portable terminal 4 is interposed between the wearable device 3 and the seat air conditioner 2, the camera 35 may be included in the portable terminal 4. In the configuration in which the portable terminal 4 is interposed between the wearable device 3 and the seat air conditioner 2, the configuration including the portable terminal 4 and the wearable device 3 corresponds to the user device. Furthermore, the mobile terminal 4 may have a function as the wearable device 3 such as the biosensor 32.

<About functions of wearable control unit 31>
In the wearable device 3, a seat air conditioning application Ap1 is installed as one of the applications. The seat air conditioning application Ap1 is stored in the flash memory 313, for example.

  The wearable control unit 31 causes the remote control unit F1, the biological information acquisition unit F2, the sleep state determination unit F3, the getting-off time acquisition unit F4, and the air conditioning setting acquisition unit illustrated in FIG. 7 when the CPU 311 executes the seat air conditioning application Ap1. Functions as F5 and connection processing unit F6 are provided. Part or all of the functions executed by the wearable control unit 31 may be realized as hardware. The aspect realized as hardware includes an aspect realized using one or a plurality of ICs in addition to an aspect realized using analog circuit elements.

  The wearable control unit 31 includes a user setting storage unit M1. The user setting storage unit M1 only needs to be rewritable and realized using a nonvolatile storage medium. For example, the user setting storage unit M1 is realized by using a part of the storage area provided in the flash memory 313.

  The remote operation unit F1 causes the wearable device 3 to function as a remote controller that controls the operation of the seat air conditioner 2 when the communication connection between the wearable communication unit 34 and the seat side communication unit 24 is established. The remote operation unit F1 causes the display unit 331 of the wearable HMI 33 to display a screen (hereinafter referred to as a remote operation screen) for the user to input a control target value of the air conditioning unit 22 such as a set temperature and an air volume. When a user operation is performed on the remote operation screen, a command signal corresponding to the operation is transmitted to the seat air conditioner 2 in cooperation with the wearable communication unit 34.

  Thereby, the seated person can set the set temperature of the conditioned air provided by the seat air conditioner 2 to the temperature desired by the seated person via the wearable device 3, for example. The remote operation unit F1 causes the wearable HMI 33 to display information indicating the current operating state of the seat air conditioner 2 as a part of the remote operation screen or another screen. As described above, the seat air conditioning application Ap1 provides a function (hereinafter, a remote operation function) for remotely operating the seat air conditioner 2 as one function.

  The biological information acquisition unit F2 acquires a pulse wave signal from the biological sensor 32. Moreover, the biometric information acquisition unit F2 analyzes the pulse wave signal acquired by the biometric information acquisition unit F2, thereby enabling the user's pulse rate (in other words, heart rate), the activity level of the autonomic nerve, the respiratory rate, Calculate blood pressure, etc.

  The pulse rate (in other words, the heart rate) can be calculated based on the peak interval of pulse waves (so-called RRI: R-R Interval). For example, a value obtained by dividing 60 seconds by the average value or median value of RRI per fixed time can be used as the pulse rate. The activity state of the autonomic nerve can be specified by the presence or absence of RRI fluctuation. The active state of the autonomic nerve includes whether the sympathetic nerve or the parasympathetic nerve is active (in other words, superior). The degree of sympathetic nerve activity also functions as an indicator of whether the user feels stress or is relaxed.

  The respiration rate is the respiration rate per fixed time. The respiration rate per certain time can be specified by the number of peaks of the envelope of the pulse wave in the time zone. The peak interval of the pulse wave envelope represents the rhythm of respiration. Therefore, the biological information acquisition unit F2 can specify the respiratory rate and the respiratory rhythm from the pulse wave signal. The blood pressure can be specified from the distribution of feature points provided in a waveform (so-called acceleration pulse wave) obtained by differentiating the pulse wave twice with respect to time. The acceleration pulse wave is also academically called a second-order differential pulse wave.

  For example, the sleep state determination unit F3 determines whether the user's state corresponds to “awake state”, “REM sleep”, or “non-REM sleep” based on the heart rate. “Awakening state”, “REM sleep”, and “Non-REM sleep” indicate the user's sleep state (hereinafter, sleep state). The “wake state” corresponds to a state where the user is awake (in other words, not sleeping). “REM sleep” generally tends to be a state where sleep is shallow. “Non-REM sleep” tends to be deep sleep. Various methods can be used as the method for estimating the sleep state. For example, the sleep state determination unit F3 may be configured to estimate the user's sleep state using the user's body temperature, breathing rhythm, and the like in addition to the heart rate. Furthermore, the sleep state determination unit F3 may be configured to detect the user's sleep from other biological information without using the heart rate. The sleep state determination unit F3 corresponds to a seated person state estimation unit.

  The getting-off time obtaining unit F4 cooperates with the wearable HMI 33 to obtain the time when the user gets off the bus (in other words, the time when the use of the seat 1 is finished) based on a user operation on the input device 332. The timing at which the getting-off time acquiring unit F4 performs the process for acquiring the getting-off time may be, for example, when communication connection between the wearable communication unit 34 and the seat side communication unit 24 is established. Further, when the seat 1 used by the user is a reserved seat, it may be performed when the user reserves the seat 1.

  Note that the information that the user inputs by operating the input device 332 can be, for example, the name of the stop (that is, the destination) that the user is scheduled to get off. This is because once the destination is determined, the getting-off time can be specified from the required time to the destination. Here, as an example, if the user inputs a stop scheduled to get off the bus, the get-off time acquisition unit F4 is configured to specify the get-off time by referring to a bus schedule prepared separately. It shall be. Of course, as another aspect, the information that the user inputs by operating the input device 332 may be the scheduled time when the user gets off the bus. The getting-off time acquisition unit F4 corresponds to the absence time acquisition unit. Moreover, the getting-off time corresponds to the leaving time.

  The air conditioning setting acquisition unit F5 cooperates with the wearable HMI 33 to acquire air conditioning setting information that determines the operation mode of the seat air conditioner 2 according to the user's state based on a user operation on the input device 332. The air conditioning setting information is a data set indicating a target value (in other words, air conditioning setting) for each control item such as a set temperature, air volume, and humidity.

  The air conditioning setting acquisition unit F5 sets, as the air conditioning setting information, setting information for awakening that defines the operation mode of the air conditioning unit 22 when the seated person is awake, and the operation mode of the air conditioning unit 22 when the seated person is sleeping. And setting information for sleep that regulates. In other words, the setting information for awakening is data representing the air conditioning setting applied when the user is awake, and the setting information for sleeping is the data representing the air conditioning setting applied when the user is asleep. It is.

  As a more preferable aspect, the setting information for awakening further includes normal setting information indicating air conditioning settings (hereinafter referred to as normal settings) applied when the seated person desires to maintain a state of waking up, and a seated person. Sleep setting information indicating an air conditioning setting that induces sleep (hereinafter referred to as sleep setting). For example, when the communication connection between the wearable communication unit 34 and the seat side communication unit 24 is established, whether the normal setting or the sleep setting is applied as the air conditioning setting when the user is awake. It may be selected by the user. Further, whether the normal setting or the sleep setting is applied as the air conditioning setting in the state where the user is awake may be configured so that the user can change the setting as needed by operating the input device 332. Since the temperature or the like at which sleep is easy to change depends on the season, the sleep setting may be changed for each season.

  Moreover, the setting information for sleep is a primary mode setting information which shows the air-conditioning setting (henceforth primary sleep setting) applied until a predetermined time passes after a seated person starts sleeping as a more preferable aspect. Secondary sleep setting information indicating air conditioning settings (hereinafter referred to as secondary sleep settings) applied after a predetermined time has elapsed since the seated person began to sleep. The primary sleep setting information defines the operation mode of the air conditioning unit 22 from when the seated person starts to sleep until a predetermined time elapses. The secondary sleep setting information is the predetermined time after the seated person starts sleeping. It defines the operation mode of the air conditioning unit 22 after the passage.

  The time for maintaining the primary sleep setting (hereinafter, mode switching time) is, for example, 1 hour. The mode switching time is preferably configured to be settable by the user. In other words, the mode switching time corresponds to the time from when the user falls asleep until the secondary sleep setting is applied. The mode switching time is also included in the air conditioning setting information.

  Furthermore, the setting information for sleep is the setting information for awakening which shows the air-conditioning setting (henceforth the setting for awakening) applied when the remaining time until the getting-off time becomes a predetermined remaining threshold value or less in the state where the user is sleeping. Is also registered. The awakening setting is an air conditioning setting for guiding the user to the awakening state. The setting for awakening is, for example, an air conditioning setting for stopping the air conditioning control or setting the set temperature to a relatively high temperature.

  Hereinafter, for simplification of description, only the set temperature of the conditioned air will be referred to as the control item of the seat air conditioner 2, but the humidity and the air volume may be set appropriately by the user as well. As another aspect, the seat air conditioner 2 may be configured to be adjustable only in temperature. Various setting information set by the user is stored in the user setting storage unit M1.

  FIG. 8 is a diagram illustrating an example of air conditioning setting information set by the user. The set temperature in each state is set by the user. Although FIG. 8 shows an aspect in which the user designates a specific temperature as the air conditioning setting, the present invention is not limited to this. As illustrated in FIG. 9, the air conditioning setting information may indicate an amount of change with respect to a predetermined default temperature set in the seat air conditioner 2. The default temperature is set automatically or manually by a bus crew or the like based on the outside air temperature or the like. The default temperature is the temperature that is estimated to be comfortable for many passengers. As the default temperature, the same temperature is set for the air conditioning units 22 of all the seats 1.

  In addition, the air conditioning setting information is not information in which specific numerical values such as temperature are registered, but may be information specifying whether to maintain the default state, weaken the air conditioning, or strengthen the air conditioning, for example. The air conditioning setting information may include an option for stopping air conditioning. Further, as shown in FIG. 10, the air conditioning setting for each user state may be set such that the operation of the air conditioning unit 22 stops when the user falls asleep.

  The connection processing unit F6 is configured to perform processing for establishing a communication connection with the seat air conditioner 2 based on a user operation. For example, when the camera 35 captures a connection two-dimensional code based on a user operation, the connection processing unit F6 uses the air conditioner identification information (specifically, the BD address) indicated by the connection two-dimensional code as a connection destination. The device (here, the seat air conditioner 2) is specified. Then, the communication connection with the seat air conditioner 2 is established by transmitting a connection request to the seat air conditioner 2 in cooperation with the wearable communication unit 34. Note that, as a specific method for establishing a communication connection including transmission of a connection request, various methods such as a method defined in the Bluetooth standard can be used.

  The wearable control unit 31 provides an automatic air conditioning function that automatically changes the set temperature of the conditioned air according to the user's state by executing the seat air conditioning application Ap1 that provides the above functions. Schematically, the wearable control unit 31 executing the seat air conditioning application Ap1 uses a signal input from the biometric sensor 32 to determine the user's state such as whether the user is sleeping or waking up. And air-conditioning control according to a user's sleep level is implement | achieved in cooperation with seat air-conditioning ECU21. In the configuration in which the portable terminal 4 is interposed between the wearable device 3 and the seat air conditioner 2, the seat air conditioning application Ap1 may be installed in the portable terminal 4.

  When the wearable device 3 determines that an operation for establishing a communication connection with the seat air conditioner 2 has been performed by the user, the wearable device 3 performs wireless communication with the seat air conditioner 2 according to the flow of the sheet cooperation processing illustrated in FIG. Hereinafter, the sheet cooperation process performed by the wearable device 3 will be described with reference to FIG.

  Note that the flowchart shown in FIG. 11 may be started when an operation for establishing a communication connection with the seat air conditioner 2 is performed by the user. For example, when the two-dimensional code including the air conditioner identification information (that is, the two-dimensional code for connection) is imaged using the camera 35, the sheet linkage process is started. Of course, the operation for establishing the communication connection with the seat air conditioner 2 is not limited to this, and various operations can be employed.

  In step S101, the connection processing unit F6 analyzes the connection two-dimensional code imaged by the camera 35, extracts air conditioner specifying information such as a BD address, and proceeds to step S102. In step S102, the connection processing unit F6 transmits a connection request to the seat air conditioner 2 of the seat on which the user is seated using the air conditioner specifying information acquired in step S101, and the communication connection with the seat air conditioner 2 is established. Establish. When the process in step S102 is completed, the process proceeds to step S103.

  In step S103, the getting-off time obtaining unit F4 obtains getting-off time information based on a user operation in cooperation with the wearable HMI 33. When the getting-off time acquisition unit F4 acquires the getting-off time information, the getting-off time information is transmitted to the seat air conditioner 2 in cooperation with the wearable communication unit 34. When the process in step S103 is completed, the process proceeds to step S104.

  In step S104, the air conditioning setting acquisition unit F5 acquires the air conditioning setting information based on the user operation in cooperation with the wearable HMI 33. When acquiring the air conditioning setting information, the air conditioning setting acquisition unit F5 transmits the acquired air conditioning setting information to the seat air conditioner 2 in cooperation with the wearable communication unit 34.

  When the air conditioning setting information is already registered in the user setting storage unit M1, the user's input of air conditioning settings in step S104 can be omitted. When the air conditioning setting information is registered in the user setting storage unit M1, the air conditioning setting information registered in the user setting storage unit M1 may be read out and transmitted to the seat air conditioner 2 in step S104. It is assumed that the seat air conditioning application Ap1 is configured so that the registered air conditioning setting information can be changed at an arbitrary timing.

  In step S105, the sleep state determination unit F3 determines the user's state (here, the sleep state) based on the biological information acquired by the biological information acquisition unit F2. Then, the determination result is transmitted to the seat air conditioner 2 in cooperation with the wearable communication unit 34.

  In step S106, the connection processing unit F6 determines whether the communication connection with the seat air conditioner 2 is maintained. When the communication connection with the seat air conditioner 2 is maintained, an affirmative decision is made in step S106 and step S105 is executed again.

  Note that the communication connection between the wearable device 3 and the seat air conditioner 2 ends when the wearable device 3 goes out of the communication range of the seat air conditioner 2. That is, the user can end the communication connection between the wearable device 3 and the seat air conditioner 2 by getting off the bus.

  The wearable control unit 31 is configured to repeatedly execute step S105 at a predetermined reporting interval while the communication connection with the seat air conditioner 2 is maintained. The reporting interval is set to such a length that the user state can transition, such as 1 minute, 3 minutes, or 10 minutes. When the communication connection with the seat air conditioner 2 is disconnected (in other words, terminated), a negative determination is made in step S106 and this flow is terminated.

  In this embodiment, while the communication connection with the seat air conditioner 2 is maintained, the data indicating the state of the user is repeatedly transmitted by sequentially performing step S105. However, the data to be repeatedly transmitted is not limited thereto. Absent. For example, the air conditioning setting information and the getting-off time information may be periodically transmitted. In addition, when the air conditioning setting information is changed by the user during the sheet linkage process, the changed air conditioning setting information is transmitted. In addition, when the remote operation function is used by the user during the sheet cooperation process, a command signal corresponding to the operation content is transmitted. The seat air conditioning application Ap1 is configured to be able to switch on / off of the automatic air conditioning function based on a user operation. The on / off of the automatic air conditioning function may be selected by the user when the communication connection between the wearable communication unit 34 and the seat side communication unit 24 is established.

<Function of seat air conditioning ECU 21>
Next, functions of the seat air conditioning ECU 21 will be described. For example, when the vehicle is in an ignition-on state, the seat air-conditioning ECU 21 turns on the power supply of the air-conditioning unit 22, the seat-side communication unit 24, and the seat-side HMI 23, and starts these operations.

  The seat air conditioning ECU 21 operates the air conditioning unit 22 in the normal mode in which the set temperature is set to a predetermined default temperature until it is determined that a seated person is seated on the seat 1 after the vehicle is in the ignition-on state. The air conditioning unit 22 in the normal mode adjusts the temperature and air volume of the air blown from the seat outlet so that the temperature of the enclosed air-conditioned space 200 is maintained at a predetermined default temperature. Before the seated person sits on the seat 1, the temperature of the enclosed air-conditioned space 200 is set to the default temperature, thereby providing a comfortable temperature environment for the seated person immediately after sitting.

  Various methods can be adopted as a method for determining whether or not a seated person is seated on the seat 1. For example, the seat air conditioning ECU 21 may perform seating determination based on the output of a seating sensor provided on the seat 1. Alternatively, when the vehicle is a reserved seat bus, the seating of each seat 1 may be determined by estimation based on the reserved seat reservation status indicating the boarding position and the current position of the vehicle.

  When the seat 1 is a designated seat such as a bus or a train, the seat air conditioning application Ap1 may be used to register a desired temperature in advance in the server or the like before boarding. In this case, the seat air-conditioning ECU 21 may communicate with a server or the like through the seat-side communication unit 24 to acquire a temperature desired by the seated person and perform air-conditioning by the air-conditioning unit 22 in advance using this temperature as a set temperature. .

  Furthermore, when the seat-side communication unit 24 receives a connection request from the wearable device 3, the seat air-conditioning ECU 21 performs the automatic air-conditioning control process according to the flow of the automatic air-conditioning control process shown in FIG. The automatic air conditioning control process is a process of dynamically changing the operation mode (for example, set temperature) of the air conditioning unit 22 according to the state of the user as a seated person. Hereinafter, the automatic air-conditioning control process will be described with reference to FIG.

  First, in step S201, based on a connection request from the wearable device 3, a communication connection with the wearable device 3 is established, and the process proceeds to step S202. In step S202, the getting-off time information transmitted from the wearable device 3 is acquired in cooperation with the seat side communication unit 24, and the process proceeds to step S203. In step S203, the air conditioning setting information transmitted from the wearable device 3 is acquired in cooperation with the seat side communication unit 24, and the process proceeds to step S204. The seat air conditioning ECU 21 that executes step S203 corresponds to a seat side air conditioning setting acquisition unit.

  In step S204, air-conditioning control (hereinafter, automatic air-conditioning control) based on the air-conditioning setting information acquired in step S203 and the seated person's state sequentially provided from the wearable device 3 is started. In addition, since a user operation is required for the connection between the seat air conditioner 2 and the wearable device 3, it is assumed that the seated person is not sleeping at the time of execution of step S204. Therefore, when the automatic air-conditioning control is started, it is assumed that the seated person is in the awake state, and the air-conditioning setting corresponding to the awake state (that is, the setting for awakening) is applied. When the user is instructed to apply the sleep setting as a seated person, the sleep setting may be applied. If application of the sleep setting is not instructed, the normal setting may be applied. During the execution of the automatic air conditioning control, the seat air conditioning ECU 21 operates the air conditioning unit 22 with the air conditioning setting corresponding to the state of the user as the seated person.

  In step S205, the sleep state of the seated person transmitted from the wearable device 3 is acquired in cooperation with the seat side communication unit 24, and the process proceeds to step S206. In step S206, the air conditioning setting information is referred to, and the set temperature corresponding to the sleep state (that is, the seated person's state) acquired in step S205 is set as the control target value of the air conditioning unit 22. That is, the control target value of the air conditioning unit 22 is updated according to the user's state.

  In step S207, it is determined whether the communication connection with the seat air conditioner 2 is maintained. When the communication connection with the wearable device 3 is maintained, step S207 is affirmed and step S205 to step S206 are executed again. The execution interval of steps S205 to S206 corresponds to the reporting cycle of wearable device 3. When the communication connection with the seat air conditioner 2 is disconnected (in other words, terminated), the determination in step S207 is negative, and step S208 is executed.

  In step S208, the automatic air-conditioning control is terminated and the process proceeds to step S209. In step S209, the air conditioning unit 22 is operated at the default temperature. That is, the temperature of the enclosed air-conditioned space 200 is shifted to a predetermined default temperature.

<Summary of Embodiment>
According to the above configuration, the seat air-conditioning ECU 21 sequentially performs steps S205 to S206 while the communication connection with the wearable device 3 is maintained. For this reason, while the communication connection with the wearable device 3 is maintained, the automatic air-conditioning control according to the state of the seated person is continued.

  For example, when the sleep of the seated person is detected while the communication connection with the wearable device 3 is maintained, the air conditioning unit 22 is operated with the primary sleep setting. The case where the sleep of the seated person is detected corresponds to the case where the sleep state of the seated person becomes non-REM sleep or REM sleep. When a predetermined mode switching time (for example, 1 hour) has elapsed since the seated person fell asleep, the air conditioning unit 22 is started to operate with the secondary sleep setting. As a premise, it is assumed that the seat air conditioning ECU 21 is configured to measure an elapsed time after the seated person falls asleep.

  Further, in a state where the remaining time until the getting-off time is less than a predetermined residual threshold, the air conditioning unit 22 is operated with the awakening setting after the time when the seated person's state becomes REM sleep. In addition, the timing which applies the setting for awakening is not limited to the timing mentioned above. For example, the seat air conditioning ECU 21 may be configured to apply the awakening setting when the remaining time until the getting-off time is less than a predetermined remaining threshold.

  According to said structure, since the air-conditioning setting according to a user's sleep state is applied automatically, the user's comfort as the seated person of the seat | sheet 1 can be improved.

  Further, according to the above configuration, the seat air conditioning ECU 21 returns the set temperature of the air conditioning unit 22 to the default temperature when the communication connection with the wearable device 3 is disconnected. Thereby, the temperature of the enclosed air-conditioned space 200 also shifts to a predetermined default temperature. The communication connection between the wearable device 3 and the seat air conditioner 2 is automatically terminated when the user gets off the bus and the wearable device 3 goes out of the communication range of the seat air conditioner 2. That is, the conditioned air provided by the seat air conditioner 2 automatically returns to the default state after the occupant gets off. Therefore, when the user gets off the bus, the user does not need to perform an operation to return the set temperature or the like of the seat air conditioner 2 to the default value. Here, the default state is a state in which the temperature of the conditioned air is a default temperature preset by a bus crew or the like.

  The seat air conditioning ECU 21 operates the air conditioning unit 22 in a default state when the seat 1 is not used. According to such a configuration, even in a situation where another user (hereinafter referred to as the second user) uses the seat 1 used by a certain user (hereinafter referred to as the first user) after getting off the first user. At the timing when the first user gets off, the conditioned air is once returned to the default state. Therefore, the possibility that the second user may come into contact with the conditioned air reflecting the preferences of the first user can be reduced.

  The embodiments of the present disclosure have been described above. However, the present disclosure is not limited to the above-described embodiments, and various modifications described below are also included in the technical scope of the present disclosure. However, various modifications can be made without departing from the scope of the invention. For example, the following various modifications can be implemented in appropriate combination within a range where no technical contradiction occurs.

  In addition, about the member which has the same function as the member described in the above-mentioned embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted. In addition, when only a part of the configuration is mentioned, the configuration of the above-described embodiment can be applied to the other portions.

[Modification 1]
In the above, the seat air conditioning ECU 21 acquires the air conditioning setting information reflecting the preference of the user as a seated person from the wearable device 3, and dynamically changes the operation mode of the air conditioning unit 22 based on the air conditioning setting information and the seated person's state. However, the present invention is not limited to this. For example, the seat air conditioning ECU 21 is configured to dynamically control the operation mode of the air conditioning unit 22 based on the air conditioning setting information indicating the air conditioning setting for each seated person state generated by the designer and the like, and the seated person state. May be.

  For convenience, hereinafter, the air conditioning setting information set by the user and reflecting the user's own preferences is also referred to as user setting information. The standard air conditioning setting information generated by the designer or the like is also described as standard air conditioning setting.

[Modification 2]
In the above, the seat air conditioning ECU 21 has disclosed a mode in which the information indicating the air conditioning setting for each seated person state (that is, the air conditioning setting information) is disclosed from the wearable device 3, but the present invention is not limited thereto. The seat air conditioning ECU 21 may be configured to cooperate with the seat side HMI 23 and acquire air conditioning setting information based on a seated person's operation on the seat side HMI 23. That is, the seat air conditioning ECU 21 may have a function corresponding to the air conditioning setting acquisition unit F5.

  Similarly, the seat air conditioning ECU 21 may be provided for the getting-off time acquisition unit F4. That is, the seat air-conditioning ECU 21 may be configured to cooperate with the seat-side HMI 23 and acquire the getting-off time information based on a seated person's operation on the seat-side HMI 23.

[Modification 3]
The seat air conditioning ECU 21 may include a function for determining the user's state based on the detection result of the biological sensor 32 (for example, the sleep state determination unit F3). Further, the biosensor 32 may be built in the seat 1. In realizing the seat air conditioning system 100, the wearable device 3 is an optional element.

[Modification 4]
In the embodiment described above, a configuration capable of registering two types of air conditioning settings, a normal setting and a sleep setting, is disclosed as the setting for awakening, but the present invention is not limited thereto. It is not necessary to have a sleep setting. Moreover, although the aspect provided with three types of air-conditioning settings of the setting for primary sleep, the setting for secondary sleep, and the setting for awakening was disclosed in the aspect mentioned above, it is not restricted to this. There may be only two types of settings for sleep, an air conditioning setting corresponding to the primary sleep setting and an awakening setting. Moreover, it is not necessary to have the setting for awakening.

  Note that, according to the aspect in which the mode switching time is set to 0 minutes in the above-described embodiment, the setting for secondary sleep is applied immediately after sleep onset is detected. That is, the configuration in which the mode switching time is set to 0 minutes corresponds to a configuration that does not substantially include the primary sleep setting. In the embodiment described above, according to the aspect in which the mode switching time is set to a sufficiently large value with respect to the bus operation time, such as 24 hours, the setting for secondary sleep is not applied. That is, the configuration in which the mode switching time is set to a sufficiently large value corresponds to a configuration that does not substantially include the secondary sleep setting.

[Modification 5]
The seat air-conditioning ECU 21 is configured to adjust the setting of the air-conditioning unit 22 based on the remaining time until the disembarking time so that the state of the enclosed air-conditioned space 200 becomes the default state at the timing when the user disembarks. Also good. For example, as shown in FIG. 13, the seat air conditioning ECU 21 gradually brings the setting of the air conditioning unit 22 closer to the setting corresponding to the default state (hereinafter, default setting) as the getting-off time approaches.

  According to such a configuration, even in a situation in which the second user uses the seat 1 used by the first user after the first user gets off, the second user reflects the preference of the first user. The risk of coming into contact with air can be further reduced.

[Modification 6]
Although the aspect which controls operation | movement of the air conditioning unit 22 according to whether the seated person is sleeping was disclosed above, the state of the user as an index for changing the operation aspect of the air conditioning unit 22 is not limited to this. Absent. For example, the operation mode of the air conditioning unit 22 may be changed depending on whether the user is running before getting on the bus (that is, whether the user has run to the bus stop). Here, an example of an embodiment corresponding to the above technical idea is disclosed as a modified example 6.

  The wearable device 3 of this modification includes an acceleration sensor 36 as shown in FIG. Further, as shown in FIG. 15, the wearable control unit 31 includes an exercise state determination unit F7 that sequentially determines whether the user is running based on the detection result of the acceleration sensor 36 (for example, every second). Various methods can be used as the method for determining whether or not the user is running based on the detection result of the acceleration sensor 36. The determination result of the exercise state determination unit F7 is held in the RAM 312 or the like for a certain time. The determination result storage period may be, for example, 3 minutes. For convenience, the time-series data of the determination result of the exercise state determination unit F7 stored in the RAM 312 is referred to as exercise history data.

  In addition, when the communication connection with the seat air conditioner 2 is established, the exercise state determination unit F7 refers to the exercise history data stored in the RAM 312 and determines whether or not the user is running before getting on the bus. . For example, in a period of 3 minutes or less from the time when the communication connection with the seat air conditioner 2 is established, if the user is running for a predetermined time or more (for example, 30 seconds or more), the user is running before getting on the bus. judge. In other cases, it may be determined that the user was not running before boarding the bus. Then, the exercise state determination unit F7 transmits the determination result of whether or not the user was running before getting on the bus to the seat air conditioner 2 in cooperation with the wearable communication unit 34. The exercise state determination unit F7 also corresponds to a seated person state estimation unit.

  When the seat air conditioning ECU 21 of the present modification obtains a determination result that the user was running before getting on the bus from the wearable device 3, the seat air conditioning ECU 21 corrects the set temperature so that the user feels cool. For example, when the seat air conditioning ECU 21 obtains a determination result that the user was running before getting on the bus from the wearable device 3, the set temperature of the air conditioning unit 22 is set by the user indicated by the default temperature or the user setting information. Set the temperature lower than the temperature.

  According to such a configuration, if the user runs to a bus stop such as a bus stop, the risk of feeling uncomfortable by sweating after boarding the bus can be reduced. In general, humans are more likely to sweat after having stopped running than when they are running. This is because the human body is configured so that blood concentrates on the muscles being used during exercise, but when you stop exercising, the blood concentrated on the muscles flows toward the skin and the skin temperature rises. It is.

  This modification is made with the above points in mind, and the comfort of the user as a seated person is enhanced by operating the air conditioning unit 22 in a manner corresponding to the determination result of the motion state determination unit F7. Can do.

[Modification 7]
In the above-described embodiment, the aspect in which the seat air conditioning system 100 is applied to a bus is disclosed as an example, but the vehicle to which the seat air conditioning system 100 is applied is not limited to a bus. The seat air conditioning system 100 can be applied to, for example, a train, a ship as a public transportation, an airplane, a micro mobility, and the like. Public transport here refers to transport used by an unspecified number of passengers. Public transport includes, for example, taxis.

  Buses include on-demand buses as well as shared buses. Trains include subways, bullet trains, superconducting magnetic levitation railways (in other words, magnetic levitation linear motor cars). The ultra-compact mobility is, for example, a small electric vehicle having about 1 to 2 passengers. The seat air conditioning system 100 can be applied to a vehicle that provides mobility services such as automatic transportation of people and luggage, car sharing, and ride sharing.

  The vehicle to which the seat air conditioning system 100 is applied may be a vehicle that is automatically driven by an electronic control device (so-called ECU: Electronic Control Unit) installed in the vehicle.
