As shown in FIG. 4, the seat air conditioner 40 includes a seat air conditioning ECU 41, a seat air conditioning unit 42, and a seat HMI 43.

  The seat air conditioning unit 42 is a mechanical configuration that cools and heats air. As shown in FIG. 5, the air conditioning unit 42 includes a refrigeration cycle apparatus 420, a heating apparatus 425, a first blower 426, and a second blower 427. Further, the sheet air conditioner 40 is provided below the seat surface of the sheet Se as shown in FIG. 6, for example.

  The refrigeration cycle apparatus 420 cools air using a vapor compression refrigeration cycle of a refrigerant, and includes a compressor 421, a condenser 422, a pressure reduction unit 423, and an evaporator 424. The compressor 421, the condenser 422, the pressure reducing unit 423, and the evaporator 424 are provided in a bypass line which is a closed circuit in which the refrigerant flows. As a refrigerant, it may be configured to use a fluorocarbon gas having a small global warming potential such as R134a, R152a or the like, or an HC gas such as propane.

  The compressor 421 is an electric compressor driven by a DC voltage supplied from the on-board battery 70, and compresses the refrigerant flowing in the bypass line to raise the refrigerant temperature. The compressor 421 sucks the low pressure refrigerant, pressurizes the low pressure refrigerant, and discharges the high pressure refrigerant. The compressor 421 supplies the compressed high-pressure refrigerant to the condenser 422.

  The condenser 422 dissipates the heat of the refrigerant by providing heat exchange between the air blown by the first blower 426 and the refrigerant. The condenser 422 is also referred to as a radiator. The refrigerant radiated by the condenser 422 is supplied to the decompression unit 423. The decompression unit 423 decompresses the refrigerant supplied from the condenser 422 to generate a low-temperature low-pressure refrigerant, and supplies the refrigerant to the evaporator 424.

  The evaporator 424 cools the air blown by the second fan 427 by providing heat exchange between the air blown by the second fan 427 and the low temperature refrigerant. As a result, the air blown by the second fan 427 becomes cold and is supplied to the blowing duct Du (see FIG. 2). Further, the refrigerant cooled by the evaporator 424 is supplied to the compressor 421. The evaporator 424 is also called a heat sink.

  Thus, while the refrigerant circulates through the refrigeration cycle apparatus 420, the air blown by the second blower 427 is cooled and cold air is supplied to the blowing duct Du.

Note that the air outlet may be configured to be provided so as to hit the other part of the occupant seated on the seat Se, or may be provided so as to wrap the occupant with the conditioned air without directly applying the conditioned air to the occupant. It may be

  The heating device 425 is an electric heater including a PTC heater, a heat wire heater, and the like, and heats the air blown by the second blower 427. As a result, the air blown by the second blower 427 is heated and supplied to the blowing duct Du.

  The sheet HMI 43 is provided for each sheet Se, receives an operation input such as reservation setting of air conditioning from an occupant seated on the sheet Se, and displays an operation state of the sheet air conditioner 40 in the sheet Se and the like. To The seat HMI 43 receives the on / off setting of the seat air conditioner 40, the temperature setting of the air conditioning wind, the air volume setting of the air conditioning wind, and the like from the occupant seated on the seat Se via the operation input unit. As an example of the operation input unit, a mechanical switch may be used, or a touch switch integrated with a display may be used. The seat HMI 43 outputs the received information on the reservation setting of the air conditioning to the seat air conditioning ECU 41. The reservation setting of the air conditioning may be configured to be received by the sheet HMI 43 from the portable terminal 2 carried by the occupant, for example, by short-distance wireless communication via a communication module provided for each sheet Se.

  The seat air conditioning ECU 41 is mainly composed of a microcomputer provided with a processor, a memory, an I / O, and a bus connecting these, and executes various processes related to the individual air conditioning by executing a control program stored in the memory. Execution of the control program by the processor corresponds to execution of a method corresponding to the control program. As used herein, memory is a non-transitory tangible storage medium that stores non-transitory computer readable programs and data. In addition, the non-transitional tangible storage medium is realized by a semiconductor memory or a magnetic disk. The details of the process in the seat air conditioning ECU 41 will be described below.

<Schematic Configuration of Seat Air-Conditioning ECU 41>
Here, a schematic configuration of the seat air conditioning ECU 41 will be described using FIG. 4. The seat air conditioning ECU 41 includes a reservation information acquisition unit 410, a setting acquisition unit 411, a seat air conditioning unit 412, and a power consumption estimation unit 413 as functional blocks. Note that part or all of the functions executed by the seat air conditioning ECU 41 may be configured as hardware by one or a plurality of ICs or the like. Further, part or all of the functional blocks provided in the seat air conditioning ECU 41 may be realized by a combination of software execution by a processor and hardware members.

  The reservation information acquisition unit 410 acquires the reservation information output from the communication ECU 22 and received by the communication device 21 from the reservation system 3. As described above, the reservation information includes reservation settings such as the departure time of the passenger transport vehicle selected or set in the sheet reservation via the portable terminal 2, the reservation position, the use section, and the air conditioning. The reservation information acquisition unit 410 may be configured to acquire reservation information including a reservation position corresponding to the position of the seat Se in which the seat air conditioning ECU 41 is provided.

  The setting acquisition unit 411 acquires settings of individual air conditioning such as setting of on / off of the sheet air conditioner 40 from the occupant sitting on the sheet Se, temperature setting of the air conditioning wind, air volume setting of the air conditioning wind, etc. output from the seat HMI 43 .

  The sheet air conditioning unit 412 starts the operations of the refrigeration cycle apparatus 420, the heating device 425, the first blower 426, and the second blower 427, thereby supplying the conditioned duct to the blowing duct Du and performing individual air conditioning. In addition, the sheet air conditioning unit 412 adjusts the heating amount of the heating device 425 to adjust the temperature of the air conditioning air of the individual air conditioning, or adjusts the air flow of the second blower 427 to adjust the air conditioning air of the individual air conditioning. Adjust the air volume.

  The seat air conditioning unit 412 adjusts the temperature of the air conditioning wind or adjusts the air volume of the air conditioning wind according to the reservation setting of the air conditioning (that is, the individual air conditioning) acquired by the reservation information acquisition unit 410. Thus, the occupant sitting on the seat Se may adjust the conditioned air to his / her favorite temperature or to the desired air volume without setting the air conditioning after sitting on the seat Se. It will be possible. In addition, based on the departure time of the passenger transport vehicle, the seat air conditioning unit 412 makes reservation settings such as air conditioning acquired by the reservation information acquisition unit 410 from a predetermined time such as this departure time or several minutes before this departure time. It may be configured to perform the setting of the air conditioning according to.

  The seat adjustment setting included in the reservation information is obtained by the electronic control unit that controls the actuator for changing the reclining position of the seat Se, etc., and drives the actuator according to the seat adjustment reservation setting to adjust the seat adjustment. It should just be composition to do.

  Furthermore, the seat air conditioning unit 412 adjusts the temperature of the air conditioning wind or adjusts the air conditioning air volume according to the setting of the individual air conditioning received by the seat HMI 43 from the occupant seated on the seat Se acquired by the setting acquisition unit 411. To As a result, the occupant sitting on the seat Se can change the setting of the individual air conditioning even after sitting on the seat Se.

  The power consumption estimation unit 413 estimates the future power consumption of the seat air conditioner 40 using the reservation information acquired by the reservation information acquisition unit 410. Specifically, the future power consumption may be estimated according to the filling degree of the reservation indicated by the use section included in the reservation information. When reservation information acquisition unit 410 does not acquire reservation information including a reservation position corresponding to the position of seat Se provided with seat air conditioning ECU 41, that is, when there is no reservation for sheet Se, future power consumption The quantity can not be estimated. As an example, the estimation of the future power consumption according to the filling degree of the reservation indicated by the use section included in the reservation information may be performed as follows.

  First, the power consumption estimation unit 413 determines the power consumption per hour according to the reservation setting of the air conditioning included in the reservation information. The power consumption per time according to the reservation setting of the air conditioning is stored in advance in the non-volatile memory of the seat air conditioning ECU 41, for example, the correspondence between the temperature adjustment value and the air volume adjustment value and the power consumption per time. The power consumption per time according to the reservation setting of the air conditioning may be determined with reference to this correspondence. In addition, in order to determine power consumption per hour more accurately, the current adjustment value, the value of air volume adjustment, and the power consumption per hour are used for each current room temperature, It is preferable to determine the power consumption per time according to the reservation setting of the air conditioning according to the room temperature. As for the current room temperature, the seat air conditioning ECU 41 may acquire the measurement result output from the temperature sensor that measures the temperature inside the passenger transport vehicle via the in-vehicle LAN.

  Subsequently, the power consumption estimation unit 413 determines the time required to travel the use section included in the reservation information. The time required to travel the use section is, for example, stored in advance in the non-volatile memory of the seat air conditioning ECU 41 the correspondence relationship in which the time required to travel is associated in each section. The time required to travel the use section may be determined by reference. Then, the power consumption estimation unit 413 obtains the power consumption obtained by multiplying the power consumption per time determined according to the reservation setting of the air conditioning included in the reservation information by the time required to travel the use section. It may be estimated as the future amount of power required to travel the use section. The power consumption estimation unit 413 outputs the estimated future power consumption (hereinafter, individual power consumption) to the in-vehicle LAN. Note that if there is no reservation for the seat Se and the future power consumption can not be estimated, the individual power consumption may not be output to the in-vehicle LAN, or the individual power consumption is set to 0 and output to the in-vehicle LAN It may be

  The power consumption estimation unit 413 may estimate future individual power consumption required to travel the entire usage section, but in order to enable finer charge management of the on-vehicle battery 70, the future It is preferable to estimate the separately used power amount of each section or each time zone. In the case of estimating future individual power consumption by section, the time required to travel this section is determined for each section of the usage sections, and multiplied by the power consumption per time It is sufficient to estimate future individual power consumption. In addition, in the case of estimating future individual power consumption for each time zone, the time required for traveling determined for each section of the utilization sections, the time required for traveling determined, the departure time included in the reservation information Based on this, it may be configured to estimate future individual power consumption by time zone by converting to travel by time zone.

  Further, the power consumption estimation unit 413 corrects the future individual power consumption according to the setting of the individual air conditioning acquired by the setting acquisition unit 411 in order to further improve the accuracy of estimation of the individual power consumption in the future. Is preferred. In the case where the future individual power consumption is corrected according to the setting of the individual air conditioning acquired by the setting acquisition unit 411, for example, the correspondence between the value of temperature adjustment, the value of air volume adjustment, and the power consumption per hour is also included. In addition, the value of temperature adjustment by the setting of the individual air conditioning acquired by the setting acquisition unit 411, the increase and decrease of the power consumption per time for the change of the value of the air volume adjustment may be specified, and the increase and decrease may be corrected. . Further, when correcting the future individual power consumption according to the setting of the individual air conditioning acquired by the setting acquisition unit 411, the power consumption estimation unit 413 periodically or sets the setting of the individual air conditioning by the setting acquisition unit 411. The individual power consumption may be estimated sequentially, such as every acquisition.

  According to this, even if the setting of the individual air conditioning of the seat air conditioner 40 is changed after the seating of the occupant on the seat Se, it is estimated to the future individual power consumption according to the change of the setting of the individual air conditioning You can fix it. Therefore, it is possible to further improve the accuracy of estimation of future individual power consumption.

The total necessary amount estimation unit 102 estimates the future required electric energy of the entire seat air conditioner 40 by adding up the individually used electric energy acquired from the seat air conditioner ECU 41 of each seat air conditioner 40 of the passenger transport vehicle. As a result, in the total necessary amount estimation unit 102, the future required power of the entire sheet air conditioner 40 according to the filling degree of the reservation of each sheet Se according to the filling degree of the reservation indicated by the utilization section included in the reservation information. The quantity will be estimated. The total necessary amount estimation unit 102 adds up the individual power consumption estimated for each section or each time zone by section or each time zone, so that the future of the entire sheet air conditioner 40 according to each section or time zone. It is preferable to estimate the required power.

  The charge monitoring unit 103 monitors the state of charge (SOC) of the on-board battery 70 and specifies the amount of charging power of the on-board battery 70. As an example, the power amount obtained by multiplying the rated capacity of the on-board battery 70 by the SOC, which is the charging rate, may be specified as the charging power amount.

  The shortage amount calculation unit 104 calculates the shortage amount of the charging power amount of the on-board battery 70 with respect to the future required power amount estimated by the total necessary amount estimating unit 102. The shortage amount may be the amount of power corresponding to the future required amount of power estimated by the total required amount estimation unit 102. For example, the shortage may be an amount of power obtained by subtracting the amount of charge power specified by the charge monitor unit 103 from the amount of required power obtained by adding the future required power amounts by section or time zone. In addition, the shortage is also the amount of power obtained by subtracting the charge power amount specified by the charge monitor unit 103 from the power amount obtained by adding a fixed amount to the required power amount obtained by adding the future required power amounts by section or time zone. Good. The fixed amount referred to here may be, for example, the required electric energy estimated as the necessary electric energy of vehicle accessories other than the seat air conditioner 40.

  The presentation instructing unit 105 sends an instruction to present the future required electric energy estimated by the total necessary amount estimating unit 102 to the HCU 33 via the in-vehicle LAN, and the HCU 33 sends a future instruction from the display device 31 and / or the audio output device 32. Present the required power. As an example, as shown in F of FIG. 8, a numerical value indicating the required power amount obtained by adding up future required power amounts by time zone may be displayed on the display device 31 or the like. According to this, it becomes possible for the driver of the passenger transport vehicle to recognize the future required power amount, and it is possible to switch the driving operation according to the future required power amount.

  In addition, it is preferable that the presentation instructing unit 105 present the future required power amount by section or time zone estimated by the total necessary amount estimating unit 102. As an example, as shown in G of FIG. 8, a graph may be displayed on the display device 31 to indicate the future required power amount for each time zone. According to this, it becomes possible for the driver of the passenger transport vehicle to recognize the future required power by section or by time zone, and by the section according to the future required power by section or by time zone Or, it becomes possible to switch the driving operation according to the time zone.

  Furthermore, it is preferable that the presentation instruction unit 105 also sends an instruction to present the shortage calculated by the shortage calculation unit 104 to the HCU 33, and causes the display unit 31 and / or the audio output device 32 to present the shortage by the HCU 33. The display device 31 and / or the audio output device 32 correspond to a presentation device. As one example, as shown in H of FIG. 8, a numerical value indicating an insufficient amount may be displayed on the display device 31 or the like. According to this, it becomes possible for the driver of the passenger transport vehicle to recognize the shortage of the power for the future required power, and it is possible to switch the driving operation according to the shortage of the power for the future needed power. become.

  In addition, it is preferable that the presentation instruction unit 105 presents advice on driving of the passenger transport vehicle according to the shortage calculated by the shortage calculation unit 104. As an example, as shown in I of FIG. 8, a text corresponding to an advice such as “Please refrain from sudden start” may be displayed on the display device 31 or the like. For example, the presentation instruction unit 105 may be configured to present an advice for prompting the driver to reduce the power consumption in response to the increase of the shortage calculated by the shortage calculation unit 104. According to this, it is possible for the driver of the passenger transport vehicle to switch more appropriately and more easily by the driving operation according to the amount of power shortage relative to the future required power amount.

  The area specifying unit 106 specifies an area with high power generation efficiency in the generator 60 based on the information of the road structure of the planned route of the passenger transport vehicle. As an example, the area specifying unit 106 specifies the route to the destination acquired from the navigation device 50 as the planned route, and generates electric power by the generator 60 based on the map information of the planned route acquired from the navigation device 50. It is sufficient to specify an area with high efficiency.

  Specifically, an area in which constant-speed traveling can be continued for a long time and an area in which the regenerative brake is used may be specified as an area in which the power generation efficiency of the generator 60 is high. For example, the expressway may be identified as a region with high power generation efficiency as compared to a general road. In addition, a section in which the distance between intersections is a certain distance or more may be specified as an area with high power generation efficiency, or a section in which the longitudinal gradient falls below a certain value or a downward gradient in which the longitudinal gradient has a negative value The section continuing above may be specified as a region with high power generation efficiency. When the passenger transport vehicle is a railway vehicle, based on the information of the road structure of the planned route stored in the non-volatile memory of the center or the vehicle power management system 1 instead of the navigation device 50, The area specifying unit 106 may be configured to specify an area with high power generation efficiency.

  The charge control unit 107 controls the generator 60 to generate an insufficient amount calculated by the insufficient amount calculation unit 104, which is electric power corresponding to the required electric energy estimated by the total necessary amount estimation unit 102 and mounted on the vehicle The battery 70 is charged.

  In addition, it is preferable that the charge control unit 107 cause the on-vehicle battery 70 to be charged by preferentially generating power in the region where the power generation efficiency of the generator 60 specified by the region specifying unit 106 is high. For example, when all shortages can be generated in a region with high generation efficiency, power generation is performed only in a region with high generation efficiency, while in a region with high generation efficiency, all shortages can not be generated. In the case of (1), power generation may be performed outside the region where the power generation efficiency is high. According to this, since the insufficient amount of electric power with respect to the future required electric power is preferentially generated in the region with high generation efficiency and the on-vehicle battery 70 is charged, waste of energy used for electric power generation by the generator 60 can be further increased. It can be kept low. As a result, it is possible to further suppress the deterioration of the consumption efficiency of the traveling energy.

  When the on-board battery 70 is fully charged, the charge control unit 107 supplies the electric power generated by the generator 60 by the regenerative brake to the compressor 421 of the seat air conditioner 40 without passing through the on-board battery 70. It may be configured to

  Further, in the power control ECU 10, the charge control unit 107 is caused to generate power by sequentially estimating the required power amount in the total necessary amount estimating unit 102 and sequentially calculating the insufficient amount in the insufficient amount calculating unit 104. The power to be charged to the in-vehicle battery 70 may be corrected sequentially.
