Description

The present disclosure relates to a seat air conditioning control device that individually performs air conditioning for each seat of a transportation vehicle, and a seat air conditioning system including the seat air conditioning control device.

Japanese Patent Application Laid-Open No. 2006-242242 discloses a technique for determining the direction of insolation of a vehicle and correcting the amount of insolation entering the vehicle for each seat based on a correction coefficient corresponding to the intrusion direction set for each seat position. It is disclosed. Further, Patent Document 1 discloses a technique in which the target outlet temperature of the conditioned air blown out from each outlet of the vehicle is determined separately for the front seat side and the rear seat side of the vehicle based on the amount of solar radiation corrected for each seat. It is disclosed.

Japanese Patent No. 3965999

However, the technique disclosed in Patent Document 1 considers the intrusion direction of solar radiation into the vehicle, but does not consider the heat conduction of the outside air. Therefore, with respect to the heat conduction of the outside air, it is not possible to control the air conditioning for each position of the seat, and the comfort may be impaired depending on the seating position of the occupant. For example, when the outside temperature is high, even if the seat is on the side where the solar radiation does not enter, if the seat is close to the window, the heat conduction of the outside air has a great influence. Therefore, there is a high possibility that the air conditioning control based on the amount of solar radiation cannot control the air conditioning to a temperature suitable for the occupant in the seat near the window.

An object of this disclosure is to provide a seat air conditioning control device and a seat air conditioning system that can provide more comfortable air conditioning for an occupant of each seat of a transportation vehicle.

The above objective is achieved by a combination of the features described in the independent claims, and the subclaims define further advantageous embodiments of the disclosure. Reference numerals in parentheses in the claims indicate a correspondence relationship with specific means described in the embodiments described later as one aspect, and do not limit the technical scope of the present disclosure. ..

In order to achieve the above-mentioned object, a seat air conditioning control device of the present disclosure is used for each seat of a transportation vehicle, and a seat air conditioning unit (13) that performs individual air conditioning for an occupant sitting on the seat. ) Is a seat air-conditioning control device for controlling a seat position, the seat position specifying unit (110) for specifying a seat position of a seat for which the seat air-conditioning unit is used, and the seat position based on the seat position specified by the seat position specifying unit. The thermal conductivity specifying unit (118) for specifying the thermal conductivity, which is the degree of influence of the thermal conductivity of the outside air on the position, and the seat air conditioning unit according to the increase in the thermal conductivity specified by the thermal conductivity specifying unit. And an individual air conditioning control unit (120) for strengthening the setting of individual air conditioning.

In order to achieve the above object, a seat air conditioning system of the present disclosure is a seat air conditioning unit (13) which is used for each seat of a transportation vehicle and performs individual air conditioning for an occupant sitting on the seat. And a seat air conditioning control device (11, 11a, 11b) for controlling the seat air conditioning unit, wherein the seat air conditioning control device is a seat position for specifying a seat position of a seat in which the seat air conditioning unit is used. A specifying unit (110), and a heat conductivity specifying unit (118) that specifies the heat conductivity, which is the degree of influence of the heat conduction of the outside air on the seat position, based on the seat position specified by the seat position specifying unit. An individual air conditioning control unit (120) that strengthens the setting of the individual air conditioning in the seat air conditioning unit according to the increase in the thermal conductivity specified by the thermal conductivity specifying unit.

According to these, based on the seat position specified by the seat position specifying unit, the heat conductivity which is the degree of influence of the heat conduction of the outside air on the seat position is specified by the heat conductivity specifying unit. It is possible to specify the degree of influence of the heat conduction of the outside air that is different as the heat conductivity. Then, as the thermal conductivity specified by the thermal conductivity specifying unit increases, the individual air conditioning control unit intensifies the setting of the individual air conditioning in the seat air conditioning unit, so that the position of the degree of influence of the heat transfer of the outside air is high. The more seats, the stronger the individual air conditioning settings can be set. Therefore, it is possible to set the individual air conditioning to a setting that allows the occupant to feel more comfortable depending on the degree of influence of the heat conduction of the outside air for each seat position. As a result, it becomes possible to provide more comfortable air conditioning for the occupant of each seat of the transportation vehicle.

In the present embodiment, a case where a seat reservation is made through the mobile terminal 2 will be described as an example. As an example, the user operates the reservation-only browser of the transportation vehicle with the mobile terminal 2 through the operation input unit to access the reservation system 3 and selects a reservation item displayed in the reservation-only browser, thereby making a seat. The reservation may be made.

The selection of the reservation item includes selection of the position of the seat for which the seat is reserved (hereinafter, reserved position) and the use section for which the seat is reserved. If the transportation vehicle is a shared taxi, the use section may be between nodes such as intersections, and if the transportation vehicle is a bus, it may be between bus stops. If the body is a rail car, it may be between stations. Further, the reservation system 3 may be configured such that the reservation setting of the seat environment for the seat Se for which the seat reservation is performed is also performed via the mobile terminal 2. For example, the reservation setting of the seat environment may be the air conditioning temperature setting, the air conditioning air volume setting, or the like.

In the reservation system 3, the reservation information such as the reservation position selected in the seat reservation via the mobile terminal 2, the use section, and the reservation setting of the seat environment is stored as identification information (hereinafter, mobile ID) for identifying the mobile terminal 2 and individual It is stored in the non-volatile memory in association with identification information (hereinafter, mobile body ID) for identifying the mobile body for transportation. Further, the reservation system 3 transmits the accumulated reservation information to the mobile body side system 1 of the transporting mobile body corresponding to the mobile body ID linked to the reservation information.

<Schematic configuration of mobile-side system 1>
Subsequently, a schematic configuration of the mobile body side system 1 will be described with reference to FIGS. 1 and 2. The moving body side system 1 is used in the moving body for transportation as described above, and as shown in FIGS. 1 and 2, the seat air conditioner 10, the communication system 20, the user position specifying unit 30, the locator 40, the map. It includes a database (hereinafter referred to as map DB) 50, a body ECU 60, an outside air temperature sensor 70, and a room temperature sensor 80. It is assumed that the seat air conditioner 10, the communication system 20, the user position specifying unit 30, the locator 40, the map DB 50, the body ECU 60, the outside air temperature sensor 70, and the room temperature sensor 80 are connected to, for example, a LAN in the transportation vehicle. ..

The communication system 20 includes a communication device 21 and a communication ECU 22. The communication device 21 communicates with the reservation system 3 via a public communication network. The communication device 21 receives the aforementioned reservation information transmitted from the reservation system 3 and outputs it to the communication ECU 22. The communication ECU 22 is mainly composed of, for example, a microcomputer having a processor, a memory, an I/O, and a bus connecting these, and executes the control program stored in the memory to execute the control program stored in the memory and the LAN in the transportation vehicle. It is an electronic control device that executes various processes as a gateway (G/W) between and. The communication ECU 22 transmits the reservation information and the mobile ID, which are output from the communication device 21 and received from the reservation system 3, to a user position specifying ECU 32 of the user position specifying unit 30, which will be described later, via the LAN in the transportation vehicle.

The user position specifying unit 30 includes a receiving antenna 31 and a user position specifying ECU 32. The user position specifying unit 30 specifies the position of the user who carries the mobile terminal 2 by specifying the position of the mobile terminal 2 inside and outside the moving body for transportation.

As shown in FIG. 1, the receiving antennas 31 are provided at a plurality of locations on the transportation vehicle. The receiving antennas 31 are not limited to the configuration in which a plurality of receiving antennas 31 are provided from the front part to the rear part of the left and right side surfaces of the transportation vehicle, as shown in FIG. It may be configured. The reception antenna 31 receives a 2.4 GHz band radio wave used in BLE from the mobile terminal 2. Further, the receiving antenna 31 has an RSSI circuit that measures the reception intensity of this radio wave (hereinafter referred to as BLE radio wave intensity), and measures the BLE radio wave intensity and outputs it to the user position specifying ECU 32.

For example, the reception antenna 31 establishes a connection with the mobile terminal 2 to receive the mobile ID, measures the BLE field intensity of the radio wave used when transmitting the mobile ID, and measures the received mobile ID as the BLE. The radio field intensity is output to the user position specifying ECU 32. In addition, the receiving antennas 31 other than the receiving antenna 31 that establishes a connection with the mobile terminal 2 measure the BLE radio wave intensity of this radio wave by sniffing (that is, intercepting) the radio wave used when transmitting the mobile ID. Then, the measured BLE radio wave intensity is output to the user position specifying ECU 32.

The user position specifying ECU 32 is, for example, a processor, a memory, an I/O, and a bus connecting these, and is an electronic control device that executes various processes related to the position specifying of the user by executing a control program stored in the memory. is there.

The reservation information includes the reservation position and the reservation setting of the seat environment described above. The user position specifying ECU 32 utilizes the fact that the pattern of the BLE radio wave intensity measured by each of the plurality of receiving antennas 31 changes according to the position of the portable terminal 2 inside and outside the moving body for transportation, and the user positioning ECU 32 detects The position of the portable terminal 2 inside and outside the moving body for transportation is specified based on the BLE radio field intensity measured by each. In other words, the position of the user inside or outside the moving body for transportation is specified based on the reception intensity when the radio wave transmitted from the mobile terminal 2 carried by the user is received by each of the plurality of receiving antennas 31. .. As an example, since the BLE field intensity correlates with the distance between the receiving antenna 31 and the mobile terminal 2, the BLE field intensity of at least three receiving antennas 31 among the plurality of receiving antennas 31 is used to perform triangulation. The position of the mobile terminal 2, that is, the position of the user may be specified.

In addition, the user position identification ECU 32 collates the mobile ID associated with the reservation information acquired from the communication ECU 22 with the mobile ID received from the mobile terminal 2 that is the transmission source of the radio wave used to specify the position of the user. From among the reservation information, the reservation information corresponding to this user is specified. Then, based on the reserved position included in the specified reservation information, to the seat air conditioning ECU 11 of the seat air conditioner 10 provided on the seat Se (hereinafter, reserved seat) indicated by the reserved position, the specified position of the user, The reservation information acquired from the communication ECU 22 is output.

The locator 40 includes a GNSS (Global Navigation Satellite System) receiver and an inertial sensor. The GNSS receiver receives positioning signals from a plurality of positioning satellites. The inertial sensor includes, for example, a gyro sensor and an acceleration sensor. The locator 40 combines the positioning signal received by the GNSS receiver and the measurement result of the inertial sensor to sequentially measure the current position of the transportation vehicle equipped with the locator 40. The current position is represented by the coordinates of latitude and longitude, for example. When the transportation vehicle is a vehicle, the traveling distance obtained from the signal sequentially output from the vehicle speed sensor mounted on the transportation vehicle may be used to measure the current position.

The map DB 50 is a non-volatile memory and stores map data such as link data and node data. The map data is not limited to the configuration stored in the map DB 50, and may be obtained from the server outside the transportation vehicle via the communication system 20.

The body ECU 60 includes, for example, a processor, a memory, an I/O, and a bus connecting these, and executes a control program stored in the memory to control various actuators mounted on the transportation vehicle. The body ECU 60 is connected with a courtesy switch for the door of the transportation vehicle, and acquires a signal of the courtesy switch according to opening and closing of the door of the transportation vehicle and outputs it to the LAN in the transportation vehicle.

The outside air temperature sensor 70 is a sensor that measures the outside air temperature of the transportation vehicle (hereinafter referred to as the outside air temperature). The outside air temperature sensor 70 may output the outside air temperature that is sequentially measured to the LAN in the moving body for transportation. The room temperature sensor 80 is a sensor that measures the temperature (hereinafter, room temperature) of the room in which the sheet Se is used in the transportation vehicle. The room temperature sensor 80 may output the sequentially measured room temperature to the LAN in the transportation vehicle.

The seat air conditioner 10 is provided for each seat Se of the transportation vehicle, and controls individual air conditioning (hereinafter, individual air conditioning) for an occupant seated on the seat Se. Details of the seat air conditioner 10 will be described later.

<Schematic configuration of seat air conditioner 10>
Subsequently, a schematic configuration of the seat air conditioner 10 will be described with reference to FIGS. 3 to 5. As shown in FIG. 3, the seat air conditioner 10 includes a seat air conditioning ECU 11, a seat HMI 12, a seat air conditioning unit 13, and a seat sensor 14.

The seat HMI12 is used for each seat Se, receives an operation input for setting individual air conditioning for the seat Se from an occupant seated on the seat Se, and displays an operating state of individual air conditioning for the seat Se. To do. For example, the seat HMI 12 may be configured to be provided in front of the seat Se targeted for individual air conditioning. The seat HMI 12 receives, via the operation input unit, on/off setting of individual air conditioning, temperature setting of individual air conditioning, air volume setting of individual air conditioning, and the like from an occupant seated on the seat Se. The seat HMI 12 outputs the received setting information to the seat air conditioning ECU 11. Note that the operation input for setting the individual air conditioning may be configured to be received by the seat HMI 12 from the mobile terminal 2 carried by the occupant of the seat Se, for example, by short-range wireless communication via a communication module provided for each seat Se. ..

The seat air conditioning unit 13 has a mechanical structure for cooling and heating air. As shown in FIG. 4, the seat air conditioning unit 13 includes a refrigeration cycle device 130, a heating device 135, a first blower 136, and a second blower 137. The seat air conditioning unit 13 may be provided below the seat surface of the seat Se as shown in FIG. 5, for example.

The refrigeration cycle device 130 cools air using a vapor compression refrigeration cycle of a refrigerant, and includes a compressor 131, a condenser 132, a decompression unit 133, and an evaporator 134. The compressor 131, the condenser 132, the decompression unit 133, and the evaporator 134 are provided in a bypass pipe line that is a closed circuit in which the refrigerant flows. As the refrigerant, a configuration may be used in which a fluorocarbon gas having a small global warming potential such as R134a and R152a or an HC gas such as propane is used.

The compressor 131 is an electric compressor driven by a DC voltage supplied from the battery of the transportation vehicle, and compresses the refrigerant flowing through the bypass pipe line to raise the refrigerant temperature. The compressor 131 sucks the low-pressure refrigerant, pressurizes the low-pressure refrigerant, and discharges the high-pressure refrigerant. The compressor 131 supplies the compressed high pressure refrigerant to the condenser 132. The compressor 131 is also called a compressor.

The condenser 132 dissipates the heat of the refrigerant by providing heat exchange between the air blown by the first blower 136 and the refrigerant. The condenser 132 is also called a radiator. The refrigerant radiated by the condenser 132 is supplied to the pressure reducing unit 133. The decompression unit 133 decompresses the refrigerant supplied from the condenser 132 to generate a low-temperature low-pressure refrigerant, and supplies the refrigerant to the evaporator 134.

The evaporator 134 cools the air blown by the second blower 137 by providing heat exchange between the air blown by the second blower 137 and the low temperature refrigerant. As a result, the air blown by the second blower 137 becomes cold air and is supplied to the blowing duct Du (see FIG. 5). The refrigerant cooled by the evaporator 134 is supplied to the compressor 131. The evaporator 134 is also called a heat absorber. In this way, while the refrigerant circulates in the refrigeration cycle device 130, the air blown by the second blower 137 is cooled and the cold air is supplied to the blowout duct Du.

The heating device 135 is an electric heater including a PTC heater, a hot wire type heater, and the like, and heats the warm air that has passed through the condenser 132 to further raise the temperature of the warm air. The warm air heated by the heating device 135 is also supplied to the blowing duct Du. The seat air conditioning unit 13 uses, for example, an air mix damper to distribute the amount of cool air discharged from the outlet of the cool air to the blowing duct Du, and the amount of warm air discharged from the outlet of the warm air to the blowing duct Du. The temperature of the conditioned air supplied to the blow-out duct Du is adjusted by adjusting the amount to be made.

As shown in FIG. 5, the outlet duct Du is provided with, for example, outlets on the seat surface of the seat Se, the seat back, and between the seat back and the headrest, and air-conditioning air ( The arrow (see FIG. 5) may contact the buttocks, back, neck, etc. of the occupant seated on the seat Se. The air outlet may be provided so as to hit another portion of the occupant seated on the seat Se, or may be provided so as to wrap the occupant in the conditioned air without directly applying the conditioned air to the occupant. May be

The seat sensor 14 is a sensor that outputs a signal according to whether or not an occupant is seated on the seat Se. For example, as the seat sensor 14, a seating sensor including a pressure sensitive element provided on the seating surface of the seat Se can be used. A signal depending on whether or not the occupant is seated on the seat Se is output from the seat sensor 14 to the seat air conditioning ECU 11.

The seat air conditioning ECU 11 includes, for example, a processor, a memory, an I/O, and a bus connecting these, and executes various programs related to the control of the individual air conditioning in the seat Se by executing a control program stored in the memory. It is a control device. The seat air conditioning ECU 11 corresponds to a seat air conditioning control device. The execution of this control program by the processor corresponds to the execution of the method corresponding to the control program. The memory mentioned here is a non-transitory tangible storage medium that non-temporarily stores computer-readable programs and data. The non-transitional physical storage medium is realized by a semiconductor memory, a magnetic disk, or the like. The details of the seat air conditioning ECU 11 will be described below.

<Schematic configuration of seat air conditioning ECU 11>
Subsequently, a schematic configuration of the seat air conditioning ECU 11 will be described with reference to FIG. The seat air conditioning ECU 11 includes a seat position identification unit 110, a window side determination unit 111, a door vicinity determination unit 112, a reservation information acquisition unit 113, a flow line estimation unit 114, a flow line vicinity determination unit 115, an occupant information acquisition unit 116, an open/closed state determination. The unit 117, the thermal conductivity identification unit 118, the outside air temperature acquisition unit 119, the individual air conditioning control unit 120, the room temperature acquisition unit 121, and the specified time adjustment unit 122 are provided as functional blocks.

The sheet position specifying unit 110 specifies the sheet position of the self sheet Se. As an example, the seat position of the self seat Se in the arrangement of all the seats Se of the transportation vehicle, which is stored in advance in the nonvolatile memory of the seat air conditioning ECU 11, is read and the seat position of the self seat Se is specified. It may be configured to do so. The seat position may be represented by, for example, a seat number. It is preferable that the non-volatile memory of the seat air conditioning ECU 11 also stores the arrangement of all the seats Se of the transportation vehicle.

The window edge determination unit 111 determines whether the own sheet Se is on the window of the transportation vehicle based on the seat position of the own seat Se identified by the seat position identification unit 110 and the arrangement of all the sheets Se read from the nonvolatile memory of the seat air conditioning ECU 11. Determine whether or not. By the window, the other sheet Se does not exist between the sheet position of the own sheet Se specified by the sheet position specifying unit 110 and the window of the transporting movable body closest to the sheet position. When at least one other sheet Se exists between the self-separation sheet Se and the nearest window, the window-side determination unit 111 determines that it is not the window-side. As an example, an attribute indicating whether or not each sheet Se is near the window is added to the arrangement of all the sheets Se stored in the nonvolatile memory of the seat air conditioning ECU 11, and the self-statement is performed based on this attribute. It may be determined whether or not the seat position of the seat Se is near the window.

The door vicinity determination unit 112 determines whether or not the sheet position of the own sheet Se specified by the sheet position specification unit 110 is near the door of the transportation vehicle. The door vicinity determination unit 112 determines that the own seat Se is the door of the transportation vehicle based on the seat position of the own seat Se specified by the seat position specifying unit 110 and the arrangement of all the seats Se read from the nonvolatile memory of the seat air conditioning ECU 11. It is determined whether or not The vicinity of the door is a fixed range around the door, and the range can be set arbitrarily. As an example, by assigning an attribute indicating whether or not each sheet Se is near the door to the arrangement of all the sheets Se stored in the nonvolatile memory of the seat air conditioning ECU 11, First, it may be determined whether or not the seat position of the self seat Se is near the door.

The reservation information acquisition unit 113 acquires the reservation information output from the communication ECU 22 and received by the communication device 21 from the reservation system 3 for each seat Se of the transportation vehicle. As described above, the reservation information includes the reserved position and the use section selected in the seat reservation via the mobile terminal 2.

The flow line estimation unit 114 uses the reservation information acquired by the reservation information acquisition unit 113 to determine a flow line when a user who is an occupant of the transportation vehicle gets on the transportation vehicle and sits down on the seat Se. presume. As an example, based on the reserved position acquired by the reservation information acquisition unit 113, the correspondence line between the seat position and the flow line, which is stored in advance in the nonvolatile memory of the seat air conditioning ECU 11, is referred to and the flow line is calculated. presume. When there are a plurality of reserved positions, the flow line estimating unit 114 may estimate the flow line for each of the plurality of reserved positions. In addition, the flow line estimating unit 114 preferably estimates the flow line for each use section from the use section of the reservation information, the current position specified by the locator 40, and the map data acquired from the map DB 50. .. For example, the flow line may be represented by a positional relationship or the like with respect to the arrangement of all sheets Se.

The flow line vicinity determination unit 115 determines whether or not the seat position of the own sheet Se identified by the seat position identification unit 110 is near the flow line estimated by the flow line estimation unit 114. The flow line vicinity determination unit 115 calculates the motion estimated by the flow line estimation unit 114 by the own seat Se from the seat position of the self seat Se specified by the seat position specification unit 110 and the flow line estimated by the flow line estimation unit 114. Determine if it is near the line. For example, the vicinity of the flow line may be the seat Se adjacent to the range of the flow line in the passage in the transportation vehicle.

The occupant information acquisition unit 116 acquires occupant information as to whether or not an occupant is seated on each seat Se of the transportation vehicle. The occupant information acquisition unit 116 may acquire the occupant information from the position of the user specified by the user position specifying ECU 32 and the arrangement of all seats Se read from the nonvolatile memory of the seat air conditioning ECU 11. For example, the occupant may be specified on the seat Se where the user is located, while the occupant may be specified on the seat Se where the user is not located to acquire the occupant information. Alternatively, the passenger information may be acquired by acquiring a signal from the seat sensor 14 of each seat Se via the LAN in the transportation vehicle to determine whether or not the passenger is seated.

The open/closed state determination unit 117 determines the open/closed state of the door of the transportation vehicle. As an example, the open/closed state determination unit 117 may determine the open/closed state of the door from the signal from the door courtesy switch acquired from the body ECU 60.

The thermal conductivity identifying unit 118 identifies the degree of influence of the thermal conduction of the outside air on the sheet position of the self sheet Se (hereinafter, thermal conductivity). The thermal conductivity may be expressed in a plurality of levels such as levels “0” to “4”. The higher the level value, the higher the degree of influence of the heat conduction of the outside air. The thermal conductivity specifying unit 118 specifies the thermal conductivity of the outside air to the seat position based on the seat position specified by the seat position specifying unit 110.

The thermal conductivity specifying unit 118 specifies the thermal conductivity as the seat position specified by the seat position specifying unit 110 is closer to the window side of the transportation body. The thermal conductivity identifying unit 118 preferably identifies the thermal conductivity higher when the window-side determining unit 111 determines that the window is near the window than when the window-side determining unit 111 determines that the window is not near the window. This is because the closer it is to the window of the transporting vehicle, the closer it is to the outside air, and as shown in FIG. 7, the closer it is to the window, the more easily it is affected by the heat conduction of the outside air. FIG. 7 is a diagram for explaining the degree of influence of the heat conduction of the outside air in the moving body for transportation. FIG. 7 shows an example in which the presence or absence of an occupant of each seat Se is not considered.

Further, when the window-side determination unit 111 determines that the thermal conductivity determination unit 118 is not the window-side, the occupant is seated on the other seat Se between the seat position of the own seat Se and the window of the transport vehicle closest to the seat Se. It is preferable to correct and specify the thermal conductivity depending on whether or not it is. Specifically, when the occupant is not seated on the other seat Se, the thermal conductivity is preferably corrected to be higher than that when the occupant is seated on the other seat Se. This is because if the occupant is present on the other seat Se between the self seat Se and the window, the influence of the heat conduction of the outside air is weakened by the body of the occupant. Whether or not the occupant is seated on the other seat Se between the seat position of the own seat Se and the window of the nearest transportation vehicle is based on the occupant information of the other seat Se acquired by the occupant information acquisition unit 116. First, the thermal conductivity specifying unit 118 may make the determination. The thermal conductivity in the case where the seat position of the own seat Se is not near the window and the occupant is not present in another seat Se between the own seat Se and the window is the thermal conductivity in the case where the seat position of the own seat Se is near the window. It should be specified lower than the thermal conductivity.

Here, the difference in the degree of influence of the heat conduction of the outside air depending on the presence or absence of an occupant of each seat Se in the transportation vehicle will be described with reference to FIG. SeA and SeD in FIG. 8 indicate the sheet Se at the window side, and SeB and SeC indicate the sheet Se at the window side. Further, the seat SeB has a seat SeA on which the occupant is seated, and the seat SeC is a seat SeD on which the occupant is not seated, between the seat SeC and the nearest window. In this case, the degree of influence of the heat conduction of the outside air is sheet SeA>sheet SeC>sheet SeB. The sheets SeA and SeD have the same degree of influence of the heat conduction of the outside air.

As an example, the thermal conductivity specifying unit 118 may specify the thermal conductivity as level “2” when the sheet position of the self sheet Se is near the window. Further, in the thermal conductivity specifying unit 118, the occupant is seated on the other seat Se between the seat position of the own seat Se and the window of the transport vehicle which is closest to the seat position of the own seat Se, not at the window. In this case, the thermal conductivity may be specified as the level “0”. Then, in the thermal conductivity specifying unit 118, the seat position of the own seat Se is not at the window, and the occupant is not seated on the other seat Se between the seat position of the own seat Se and the window of the transporting vehicle closest to the seat. In this case, the thermal conductivity may be specified as level "1".

Further, it is preferable that the thermal conductivity specifying unit 118 corrects and specifies the thermal conductivity when the door of the transportation vehicle is opened. This is because when the door of the transportation vehicle is opened, outside air flows into the transportation vehicle through the door, and the degree of influence of heat conduction of the outside air in the transportation vehicle temporarily changes.

In the case where the open/close state determination unit 117 determines that the door has been opened, and the door proximity determination unit 112 determines that the sheet position of the own sheet Se is near the door, the thermal conductivity determination unit 118 determines As compared with the case where it is determined that it is not near the door, it is preferable that the thermal conductivity is corrected and specified. This is because the nearer the door of the transportation vehicle is, as shown in FIG. 9, the more easily it is affected by the outside air flowing into the transportation vehicle when the door is opened. FIG. 9 is a diagram for explaining the degree of influence of heat conduction by the outside air flowing into the transporting movable body when the door is opened. The OD of FIG. 9 shows the opened door, and the dotted arrow shows the flow of the outside air that flows in.

Further, when the open/closed state determination unit 117 determines that the door is opened, the thermal conductivity determination unit 118 determines that the door vicinity determination unit 112 determines that the sheet position of the self seat Se is not near the door. In addition, when the flow line vicinity determination unit 115 determines that the sheet position of the own sheet Se is near the flow line, the thermal conductivity is corrected to be higher than when it is determined not to be near the flow line. It is preferable to specify. The thermal conductivity when the sheet position of the own sheet Se is not near the door and the sheet position of the own sheet Se is near the flow line is as follows when the sheet position of the own sheet Se is near the door. The correction amount should be smaller than the thermal conductivity.

Here, with reference to FIG. 10 and FIG. 11, the difference in the degree of influence of the heat conduction of the outside air in the transportation vehicle due to the movement of the occupant boarding the transportation vehicle to the sitting position will be described. 10 and 11 show the open door, and the dotted arrows show the flow of the outside air that flows in. Further, SPs in FIGS. 10 and 11 indicate the seating position of the occupant who gets into the transportation vehicle, and solid arrows indicate the occupant's flow line.

As shown in FIG. 10, when the seating position of the occupant boarding the transportation vehicle is near the door, the inflow of outside air into the transportation vehicle is caused by the outside air generated by opening the door shown in FIG. No big difference to the inflow. Therefore, the degree of influence of heat conduction due to the outside air flowing into the transportation vehicle also stops near the door.

On the other hand, as shown in FIG. 11, when the seating position of the occupant boarding the transportation vehicle is not near the door, the inflow of outside air into the transportation vehicle does not stop near the door, and Along the line of motion of the passenger, the passenger extends to the seated position of this occupant. This is because a flow of air is generated along with the movement of the occupant, and outside air flows in along this flow. Therefore, the degree of influence of heat conduction due to the outside air flowing into the transportation vehicle is not limited to the vicinity of the door and spreads along the flow line. Specifically, as shown in FIG. 11, the influence of heat conduction due to the outside air spreads not only on the seat Se near the door but also on the seat Se in contact with the flow line.

As an example, when the thermal conductivity specifying unit 118 corrects the thermal conductivity when the door of the transportation vehicle is opened, the thermal conductivity level specified according to the sheet position of the self-sheet Se described above and the like. The configuration may be such that correction is performed to increase For example, when the sheet position of the own sheet Se is not near the door and the sheet position of the own sheet Se is near the flow line, the correction may be made to raise the thermal conductivity level by one step. .. Further, when the sheet position of the self sheet Se is near the door, the correction may be made to raise the thermal conductivity level by two steps.

The outside air temperature acquisition unit 119 acquires the outside air temperature of the transportation vehicle. As an example, the outside air temperature acquisition unit 119 acquires the outside air temperature that is successively measured by the outside air temperature sensor 70.

The individual air conditioning control unit 120 controls the individual air conditioning by the seat air conditioning unit 13. The individual air conditioning control unit 120 controls to turn on/off the individual air conditioning, adjust the temperature of the individual air conditioning, and adjust the air volume of the individual air conditioning. Turning on/off of the individual air conditioning may be performed by starting and ending the operations of the refrigeration cycle device 130, the heating device 135, the first blower 136, and the second blower 137. The temperature may be adjusted by adjusting the amount of the cool air in the seat air conditioning unit 13 to be passed through the blowing duct Du and the amount of warm air to be passed through the blowing duct Du by the air mix damper. The adjustment of the air volume may be performed by adjusting the air volume of the first blower 136 and the second blower 137.

The individual air conditioning control unit 120 turns on and off the individual air conditioning, and turns on and off the individual air conditioning according to the settings of the individual air conditioning such as the on/off setting of the individual air conditioning, the temperature setting of the individual air conditioning, and the air volume setting of the individual air conditioning output from the seat HMI 12. Adjust the temperature and the air volume of individual air conditioning. That is, the individual air conditioning is adjusted according to the setting of the individual air conditioning by the user operation.

The individual air-conditioning control unit 120 uses the reservation information acquired by the reservation information acquisition unit 113 to perform pre-air-conditioning control for automatically starting individual air-conditioning for the reservation target seat before the occupant sits on the reservation target seat. May be In the pre-air conditioning control, the adjustment may be performed so that the temperature and the air volume are in accordance with the reservation setting of the seat environment in the reservation information acquired by the reservation information acquisition unit 113.

Moreover, the individual air conditioning control unit 120 strengthens the setting of the individual air conditioning in response to the increase in the thermal conductivity specified by the thermal conductivity specifying unit 118. The setting to be strengthened as the thermal conductivity becomes higher may be the temperature setting or the air volume setting. In the present embodiment, the following description will be given by exemplifying a case where the temperature setting is strengthened. Increasing the temperature setting means lowering the temperature of the temperature setting when cooling is performed, and increasing the temperature of the temperature setting when heating is performed. For example, each time the thermal conductivity level increases by one step, the temperature may be lowered by a predetermined value such as 1° C. in the case of cooling, while the temperature may be raised by a predetermined value such as 1° C. in the case of heating. .. When the level of thermal conductivity is “0”, the temperature setting may not be changed. In the following, a case where the temperature setting is changed by 1° C. for each level 1 step when the thermal conductivity level is “1” or higher will be described as an example.

As an example, when the temperature setting of the individual air conditioning is higher than the outside temperature acquired by the outside air temperature acquisition unit 119 by a specified value or more, the individual air conditioning control unit 120 has a high heat conductivity specified by the heat conductivity specifying unit 118. Therefore, the temperature setting may be strengthened by increasing the temperature of the individual air conditioning temperature setting. On the other hand, when the temperature setting of the individual air conditioning is lower than the outside air temperature acquired by the outside air temperature acquisition unit 119 by the specified value or more, the individual air conditioning is determined according to the increase in the thermal conductivity specified by the thermal conductivity specifying unit 118. Increase the temperature setting by lowering the temperature setting. As the temperature setting before increasing the thermal conductivity as the thermal conductivity becomes higher, there are a setting by a user operation and a setting according to a reservation setting. Further, the specified value referred to here may be any value that can distinguish between cooling and heating from the difference with the outside temperature, and can be set arbitrarily. A configuration other than the above-described example may be used to determine whether the individual air conditioning is cooling or heating, and to strengthen the temperature setting depending on whether cooling or heating.

Furthermore, the individual air conditioning control unit 120 temporarily further sets the individual air conditioning in response to the thermal conductivity specifying unit 118 correcting and specifying the thermal conductivity when the door of the transportation vehicle is opened. It is also preferable to perform a temporary emphasis control for strengthening. As a specific example, when the thermal conductivity specifying unit 118 corrects and increases the thermal conductivity level by one step when the door of the transportation vehicle is opened, the temperature setting of the individual air conditioning is temporarily further increased. The structure may be increased by 1°C.

When the door of the transportation vehicle is opened, the thermal conductivity identifying unit 118 corrects and identifies the thermal conductivity when the open/closed state determination unit 117 determines that the door is opened. In addition, when the door proximity determination unit 112 determines that the sheet position of the own sheet Se is near the door, the thermal conductivity is corrected to be higher than when the thermal conductivity determination unit 118 determines that the sheet position is not near the door. Then, it may be specified. In addition, when the open/closed state determination unit 117 determines that the door is opened, and when the door proximity determination unit 112 determines that the seat position of the own sheet Se is not near the door, and In the case where the flow line vicinity determination unit 115 determines that the sheet position of the own sheet Se is near the flow line, the thermal conductivity is corrected to be higher than that in the case where it is determined not to be near the flow line. To be

Further, when the individual air conditioning control unit 120 temporarily strengthens the setting of the individual air conditioning by the temporary emphasis control, even after the open/closed state determination unit 117 determines that the door is closed, the individual air conditioning control unit 120 continues for the specified time. It is preferable to maintain the setting of 1) and to return the setting of the individual air conditioning temporarily increased by the temporary emphasis control to the setting before the temporary emphasis control when the specified time is exceeded. The specified time may be such a time that the room temperature changed by opening the door returns to the room temperature before the door was opened. The specified time may be a fixed time in advance, but it is preferably adjusted by a specified time adjustment unit 122 described later.

The room temperature acquisition unit 121 acquires the temperature inside the room in which the sheet Se of the transportation vehicle is used. As an example, the room temperature acquisition unit 121 acquires the room temperature sequentially measured by the room temperature sensor 80.

The specified time adjustment unit 122 adjusts the specified time for returning the setting of the individual air conditioning temporarily increased by the temporary emphasis control to the setting before the temporary emphasis control. The specified time adjustment unit 122 is a specified time until the room temperature acquired by the room temperature acquisition unit 121 returns to the room temperature acquired by the room temperature acquisition unit 121 before the open/closed state determination unit 117 determines that the door has opened. Adjust. According to this, it is possible to more accurately return the room temperature changed by the opening of the door to the room temperature before the door is opened, and then return to the setting before the temporary emphasis control. The term "recovery" used herein may mean that the room temperature is the same as before the door is opened, or that the difference from the room temperature before the door is opened is within a certain range such as an error level. Good.

<Always outside air consideration control processing in the seat air conditioning ECU 11>
Subsequently, using the flowchart of FIG. 12, a flow of processing (hereinafter, always outside air consideration control processing) related to control of individual air conditioning in which outside air is taken into consideration in accordance with the seat position in the seat air conditioning ECU 11 and whether or not a passenger is seated An example will be described. The flow chart of FIG. 12 may be configured to start when the individual air conditioning in the seat Se using the seat air conditioning ECU 11 is started. In FIG. 12, description will be made assuming that the temperature setting of individual air conditioning is initially set by the above-described user operation setting or reservation setting.

First, in step S1, the sheet position specifying unit 110 specifies the sheet position of the own sheet Se. In step S2, the occupant information acquisition unit 116 acquires occupant information as to whether or not the occupant is seated on each seat Se of the transportation vehicle.

In step S3, the window edge determination unit 111 determines whether or not the own sheet Se is at the window edge of the transportation body. When it is determined to be near the window (YES in S3), the process proceeds to step S4. On the other hand, when it is determined that it is not near the window (NO in S3), the process proceeds to step S5.

In step S4, the thermal conductivity specifying unit 118 specifies the thermal conductivity higher than in the case where it is determined in S3 that it is not near the window. As an example, the thermal conductivity level “2” is specified. Then, in accordance with the high thermal conductivity, the individual air conditioning control unit 120 sets the temperature setting of the individual air conditioning to be stronger than the initial setting, and proceeds to step S8. Specifically, the temperature setting temperature is lowered in the case of cooling, and the temperature setting temperature is raised in the case of heating.

In step S5, when the occupant is seated on the other seat Se between the seat position of the self seat Se and the window of the nearest transport vehicle, that is, when the occupant is on the window side (YES in S5), Move to step S6. On the other hand, when there is no passenger on the window side (NO in S5), the process proceeds to step S7. Whether or not there is an occupant on the window side may be determined by the thermal conductivity identifying unit 118 as described above.

In step S6, the thermal conductivity identifying unit 118 identifies the thermal conductivity lower than in the case where it is determined in S5 that the occupant is not seated. As an example, the thermal conductivity level is specified as “0”. Then, the individual air conditioning control unit 120 does not change the temperature setting of the individual air conditioning from the initial setting, maintains the initial setting, and proceeds to step S8.

In step S7, the thermal conductivity identifying unit 118 identifies the thermal conductivity higher than in the case where it is determined in S5 that the occupant is seated. As an example, the thermal conductivity level “1” is specified. Then, the individual air conditioning control unit 120 sets the temperature setting of the individual air conditioning slightly stronger than the initial setting, and proceeds to step S8. Specifically, the temperature setting is set to be stronger than the initial setting while suppressing the change in the temperature setting smaller than the change in the temperature setting when it is determined to be near the window in S3.

In step S8, if it is the end timing of the always outside air consideration control process (YES in S8), the always outside air consideration control process is ended. On the other hand, when it is not always the end timing of the outside air consideration control process (NO in S8), the process returns to S2 and is repeated. Examples of the end timing of the always outside air consideration control process include that the setting of individual air conditioning is turned off, that the use section for the occupant of the own seat Se is ended, and the like. The seat air conditioning ECU 11 may determine that the use section for the occupant of the own seat Se has ended because the current position specified by the locator 40 has reached the end point of the use section of the reservation information. In addition, when it is determined to be near the window in S3, the process of S8 may be repeated without returning to S2 and repeating the process.

<Temporary Outside Air Consideration Control Process in Seat Air Conditioning ECU 11>
Next, with reference to the flowchart of FIG. 13, a process related to the control of the individual air conditioning in consideration of the outside air temporarily performed when the door of the transportation vehicle is opened in the seat air conditioning ECU 11 (hereinafter, temporary outside air consideration control process). ) Will be described. The flowchart of FIG. 13 may be configured to start when the distance to the start point of the next usage section of the transportation vehicle is less than a certain distance. The fixed distance here may be any distance as long as it can be said to be near the start point of the usage section, and can be set arbitrarily. The seat air conditioning ECU 11 determines whether or not the distance to the start point of the next usage section of the transportation vehicle has become less than a certain distance from the current position specified by the locator 40 and the map data acquired from the map DB 50. do it. In FIG. 13, the following description will be given on the assumption that the thermal conductivity specifying unit 118 has already specified the thermal conductivity and the individual air conditioning control unit 120 has controlled the individual air conditioning by the above-described constant outside air consideration control process. ..

First, in step S21, the flow line estimating unit 114 uses the reservation information acquired by the reservation information acquiring unit 113 to allow a user who is an occupant of the transportation vehicle to board the transportation vehicle in the next usage section. Then, the flow line when seated on the seat Se is estimated. In step S22, when the open/close state determination unit 117 determines that the door of the transportation vehicle is opened (YES in S22), the process proceeds to step S23. On the other hand, if it is not determined that the door is opened (NO in S22), the process of S22 is repeated.

In step S23, the door vicinity determination unit 112 determines whether or not the sheet position of the own sheet Se identified by the sheet position identification unit 110 is near the door of the transportation vehicle. Then, when it is determined that the area is near the door (YES in S23), the process proceeds to step S24. On the other hand, when it is determined that it is not near the door (NO in S23), the process proceeds to step S25.

In step S24, the thermal conductivity identifying unit 118 identifies the thermal conductivity higher than in the case where it is determined in S23 that it is not near the door. As an example, the thermal conductivity is specified by performing a correction that raises the level by two steps from the level of the thermal conductivity before the determination that the door is opened in S22. For example, when the thermal conductivity before the determination that the door is opened in S22 is level “2”, it may be specified as level “4”. Then, in accordance with the high thermal conductivity, the individual air conditioning control unit 120 sets the temperature setting of the individual air conditioning more than the temperature setting before determining that the door is opened in S22 (hereinafter, door open setting). The setting is made stronger, and the process proceeds to step S28. Specifically, the temperature setting temperature is lowered in the case of cooling, and the temperature setting temperature is raised in the case of heating.

In step S25, the flow line vicinity determination unit 115 determines whether or not the sheet position of the own sheet Se identified by the sheet position identification unit 110 is near the flow line estimated in S21. Then, when it is determined to be near the flow line (YES in S25), the process proceeds to step S26. On the other hand, when it is determined that it is not near the flow line (NO in S25), the process proceeds to step S27.

In step S26, the thermal conductivity identifying unit 118 identifies the thermal conductivity higher than in the case where it is determined in S25 that the thermal conductivity is not in the vicinity of the flow line. As an example, the thermal conductivity is specified by performing a correction to raise the level by one step from the level of the thermal conductivity before the determination that the door is opened in S22. For example, if the thermal conductivity before the determination that the door is opened in S22 is level "2", it may be specified as level "3". Then, in accordance with the high thermal conductivity, the individual air conditioning control unit 120 sets the temperature setting of the individual air conditioning slightly stronger than the door pre-opening setting, and proceeds to step S28. Specifically, the temperature setting is set to be stronger than the pre-door opening setting while suppressing a change in the temperature setting smaller than a change in the temperature setting when it is determined to be near the door in S23.

In step S27, the thermal conductivity identifying unit 118 does not correct the thermal conductivity, and the individual air conditioning control unit 120 does not change the individual air conditioning temperature setting from the pre-door opening setting. That is, the setting before door opening is maintained, and the outside air consideration control process is temporarily ended.

In step S28, when the open/close state determination unit 117 determines that the door of the transportation vehicle is closed (YES in S28), the process proceeds to step S29. On the other hand, if it is not determined that the door is closed (NO in S28), the process of S28 is repeated.

In step S29, if it is determined in step S28 that the door is closed and the specified time adjusted by the specified time adjustment unit 122 has elapsed (YES in step S29), the process proceeds to step S30. On the other hand, if the specified time has not elapsed (NO in S29), the process of S29 is repeated. In step S30, the temperature setting set stronger than the pre-door opening setting is returned to the pre-door opening setting, and the temporary outside air consideration control process ends.

Note that, in FIG. 13, using the reservation information acquired by the reservation information acquisition unit 113, a user who is an occupant of the transportation vehicle in the next use section gets on the transportation vehicle and sits on the seat Se. Although the configuration for estimating the flow line in the case has been shown, the present invention is not limited to this. For example, using the position of the user acquired from the user position specifying ECU 32 and the mobile ID corresponding to the user, the estimation result of the flow line for the user may be corrected. As an example, when the position of the user cannot be specified in the transportation vehicle, it is assumed that the user is not in the transportation vehicle and the flow line is deleted.

<Summary of Embodiment 1>
According to the configuration of the first embodiment, based on the seat position specified by the seat position specifying unit 110, the thermal conductivity specifying unit 118 specifies the thermal conductivity, which is the degree of influence of the heat conduction of the outside air on the seat position. Therefore, it is possible to specify the degree of influence of the heat conduction of the outside air, which is different for each seat position, as the heat conductivity. Then, since the individual air conditioning control unit 120 strengthens the setting of the individual air conditioning in the seat air conditioning unit 13 in response to the increase in the thermal conductivity specified by the thermal conductivity specifying unit 118, the influence degree of the heat transfer of the outside air is reduced. The higher the seat, the stronger the setting for individual air conditioning. Therefore, it is possible to set the individual air conditioning to a setting that allows the occupant to feel more comfortable depending on the degree of influence of the heat conduction of the outside air for each seat position. As a result, it becomes possible to provide more comfortable air conditioning for the occupant of each seat of the transportation vehicle.

Further, in the first embodiment, an example in which the temperature setting is strengthened in response to the increase in the thermal conductivity specified by the thermal conductivity specifying unit 118 is shown, but the temperature setting is set in accordance with the increase in the thermal conductivity. Instead of, the air volume setting may be strengthened, or the air volume setting may be strengthened in addition to the temperature setting.

This seat air conditioning ECU 11a also corresponds to a seat air conditioning control device.

The stipulated time adjustment unit 122a determines that the open/closed state determination unit 117 has opened the door for the stipulated time for returning the setting of the individual air conditioning temporarily increased by the temporary emphasis control to the setting before the temporary emphasis control. Adjust it longer as the time from when the door is closed until it is determined that the door is closed becomes longer. Regarding the correspondence between the time from opening the door to closing it and the specified time, make sure that the specified time is such that the room temperature changed by opening the door will return to the room temperature before opening the door. The configuration may be determined in advance by experiments, simulations, etc. According to this, it is possible to return the room temperature changed due to the opening of the door to the room temperature before the door is opened, and then return to the setting before the temporary emphasis control.

A configuration for adjusting the time (hereinafter, Embodiment 3) may be adopted.

The mobile system 100 of the third embodiment is the same as the mobile system 100 of the first embodiment, except that the seat air conditioning ECU 11b is included instead of the seat air conditioning ECU 11. Here, the schematic configuration of the seat air conditioning ECU 11b will be described with reference to FIG.

The seat air-conditioning ECU 11b is different from that of the first embodiment except that the room temperature acquisition unit 121 is not provided, a specified time adjustment unit 122b is provided instead of the specified time adjustment unit 122, and a passing passenger identification unit 123 is provided. It is similar to the seat air conditioning ECU 11. The seat air conditioning ECU 11b also corresponds to a seat air conditioning control device.

When the opening/closing state determination unit 117 determines that the door is opened, the passing passenger number identifying unit 123 identifies the number of passengers who pass through the door. As an example, the passing passenger number specifying unit 123 individually specifies the users moving from the inside to the outside and the inside to the outside of the transportation vehicle from the mobile ID and the position of the user acquired from the user position specifying ECU 32. The number of passengers passing through the door may be specified. In addition, by individually specifying the users moving from outside to inside the transportation vehicle, the number of passengers who pass through the door and board the transportation vehicle is specified as the number of passengers who pass through the door. Good.

The stipulated time adjustment unit 122b determines that the open/closed state determination unit 117 has opened the door for the stipulated time for returning the setting of the individual air conditioning temporarily strengthened by the temporary emphasis control to the setting before the temporary emphasis control. After that, until the door is determined to be closed, the number of people to be specified by the passing person specifying unit 123 (hereinafter, the number of passing people) is adjusted to be longer as the number of people increases. Regarding the correspondence relationship between the number of people passing through and the specified time, the specified time was obtained in advance by experiments, simulations, etc. so that the room temperature changed by opening the door would return to the room temperature before the door opened. The configuration may be set. According to this, it is possible to return the room temperature changed due to the opening of the door to the room temperature before the door is opened, and then return to the setting before the temporary emphasis control.

The configuration of the third embodiment is the same as the configuration of the first embodiment except that the method for adjusting the specified time is different. Therefore, according to the configuration of the third embodiment, the occupant for each seat Se of the transportation vehicle is also different. Will be able to provide more comfortable air conditioning.

In the case where the occupant is not seated, the configuration in which the individual air conditioning of the seat air conditioning unit 13 provided in the seat Se is strengthened is shown as compared with the case where the occupant is seated, but the present invention is not limited to this. For example, the configuration of the individual air conditioning may be strengthened by enhancing the setting of the individual air conditioning of the seat air conditioning unit 13 provided on the other seat Se between the window of the nearest transporting vehicle.

(Embodiment 5)
In the above-described embodiment, the configuration in which the seat air conditioning ECUs 11, 11a, 11b provided for each seat air conditioner 10 execute the control of the individual air conditioning for each seat air conditioner 10 has been described, but the present invention is not limited to this.
