Abstract

An air-conditioning control unit acquires in-vehicle environment information, out-vehicle environment information, and flight information in steps S101 to S103 of air-conditioning control processing. The air conditioning control unit determines whether or not a window fogging condition is satisfied in the window fogging determination process in step S104. The air conditioning control unit uses the in-vehicle environment information, the out-vehicle environment information, and the flight information when determining whether or not the window fogging condition is satisfied. When the window fogging condition is not satisfied, the air-conditioning control unit performs the internal air mode processing in step S107. In the internal air mode processing, the operation mode of the air conditioning system is set to an internal air mode. When the window fogging condition is satisfied, the air-conditioning control unit performs the outside air mode processing in step S108. In the outside air mode processing, the operation mode of the air conditioning system is set to the outside air mode. In the outside air mode, outside air is introduced as outside air introduction, and sucked outside air is introduced into the machine room.

[0020] A plurality of rotors 20 are provided on the fuselage 11. The eVTOL 10 is a multi-rotor aircraft (Japanese: マルチコプタ) having at least three rotors 20. For example, at least four rotors 20 are provided on the fuselage 11. The rotors 20 are respectively provided on the fuselage main body 12 and the wings 13. The rotors 20 rotate about a rotor axis. The rotor axis is, for example, the center line of the rotor 20. The rotors 20 are rotary wings and can generate at least one of thrust and lift for the eVTOL 10. In addition, the rotors 20 are sometimes referred to as propellers.

[0021] The rotor 20 has blades 21 and a rotor head 22. A plurality of blades 21 are arranged in the circumferential direction of the rotor axis. The rotor head 22 connects the plurality of blades 21. The rotor 20 has a rotor shaft (not shown). The rotor shaft is the rotation axis of the rotor 20 and extends along the rotor axis from the rotor head 22.

[0022] The flight modes of the eVTOL 10 include vertical takeoff, vertical landing, cruising, hovering, etc. As vertical takeoff, the eVTOL 10 can, for example, take off from a takeoff location by ascending vertically without taxiing. As vertical landing, the eVTOL 10 can, for example, land at a landing location by descending vertically without taxiing.

[0023] In addition, the flight form of the eVTOL 10 includes lifting and lowering. In lifting and lowering, the eVTOL 10 moves in the up and down directions. For example, lifting and lowering includes the eVTOL 10 rising in the vertical direction and the eVTOL 10 falling in the vertical direction. The eVTOL 10 rises upward during vertical takeoff. The eVTOL 10 falls downward during vertical landing.

[0024] The eVTOL 10 is a tilt-rotor aircraft (Japanese: チルトロータ機). In the eVTOL 10, the rotor 20 can be tilted. That is, the pitch angle of the rotor 20 can be adjusted. For example, when the eVTOL 10 ascends, the orientation of the rotor 20 is set in such a way that the rotor axis extends in the up-down direction. In this case, the rotor 20 functions as a lifting rotor for raising and lowering the eVTOL 10. The rotor 20 also functions as a hovering rotor for hovering the eVTOL 10. In addition, the hovering rotor is sometimes referred to as a hovering rotor (Japanese: ホバー用ロータ).

[0025] The eVTOL 10 has a tilt mechanism (not shown). The tilt mechanism is configured to include an electric motor and the like, and is driven to adjust the pitch angle of the rotor 20. The tilt mechanism is sometimes referred to as a tilt drive unit. For example, in the eVTOL 10, the wing 13 can be tilted relative to the fuselage body 12. That is, the rotor 20 can be tilted for each wing 13. In the eVTOL 10, the pitch angle of the rotor 20 is adjusted by adjusting the tilt angle of the wing 13 relative to the fuselage body 12. In the eVTOL 10, the mechanism for adjusting the tilt angle of the wing 13 is the tilt mechanism.

[0026] In addition, in the eVTOL 10, the rotor 20 may also be able to tilt relative to the fuselage 11. For example, the pitch angle of the rotor 20 may also be adjusted by adjusting the relative tilt angle of the rotor 20 relative to the wing 13.

[0040] Figure 2 The eVTOL 10 shown has an air conditioning system 110. The air conditioning system 110 performs air conditioning of the eVTOL 10. The air conditioning system 110 uses at least one of internal air and external air to generate conditioned air, and performs air conditioning of the eVTOL 10 with the conditioned air. For example, the air conditioning system 110 performs air conditioning of the cabin 15 by supplying conditioned air to the cabin 15.

For example, the memory 152 is a non-transitory physical recording medium that stores programs and data that can be read by a computer non-temporarily. The program 153 includes computer-readable instructions that cause the processor 151 to execute various functions. The processor 151 is a processing unit that executes a prescribed process by executing the instructions included in the program in the memory 152.

[0059] The air-conditioning control unit 150 is communicably connected to the flight control unit 40, the compression cycle device 111, and the intake switching unit 127. The air-conditioning control unit 150 performs air-conditioning control based on information from the flight control unit 40, the detection results of various sensors, and the like. The air-conditioning control includes control of the compression cycle device 111 and control of the intake switching unit 127. The control of the intake switching unit 127 includes control for switching between internal air circulation and outside air introduction.

[0060] As various sensors, the eVTOL 10 has an internal air sensor 161, an outside air sensor 165, and a barometric pressure sensor 166. The sensors 161, 165, 166 are communicably connected to the air-conditioning control unit 150. The sensors 161, 165, 166 output detection signals to the air-conditioning control unit 150. The air-conditioning control unit 150 uses the detection signals of the sensors 161, 165, 166 to obtain the detection values of the sensors 161, 165, 166.

[0061] The internal air sensor 161 is a sensor that detects the state of the internal air. The internal air sensor 161 outputs a detection signal corresponding to the state of the internal air. For example, the internal air sensor 161 detects the air state in the cabin 15 as the state of the internal air. The internal air sensor 161 is provided in the cabin 15. The internal air sensor 161 is at least one sensor. As the internal air sensor 161, there are an internal air temperature sensor, an internal air humidity sensor, a CO2 sensor, and the like.

[0062] The internal air temperature sensor is a sensor that detects the internal air temperature.

The air quality sensor outputs a detection signal corresponding to the air quality. The air quality sensor detects the air quality around the fuselage 11 as the outside air quality. The air quality sensor can detect the state of air pollution such as smoke. For example, the air quality sensor can detect the concentration of pollutant substances such as particulate matter in the atmosphere. For example, the higher the concentration of the pollutant substance, the worse the outside air quality, and it becomes a state of outside air pollution. In addition, the air quality sensor can detect the smell of the outside air. For example, the stronger the smell, the worse the outside air quality, and it becomes a state of outside air pollution.

[0065] Refer to Figure 3 the flowchart of to explain the air conditioning control process in the eVTOL 10. The air conditioning control unit 150 repeatedly executes the air conditioning control process at a prescribed control cycle. The air conditioning control unit 150 has the function of executing the processes of each step of the air conditioning control process.

[0066] The air conditioning control unit 150 obtains the in-cabin environment information in Figure 3 the step S101 shown. The in-cabin environment information is information indicating the internal environment of the eVTOL 10. The internal environment of the eVTOL 10 is sometimes referred to as the in-cabin environment. The in-cabin environment information corresponds to the internal environment information. The in-cabin environment information includes information indicating the environment of the cabin 15. As the in-cabin environment information, there are the internal air temperature, internal air humidity, CO2 concentration, presence or absence of passengers, etc. in the cabin 15. The air conditioning control unit 150 uses the detection signal of the internal air sensor 161 to obtain the internal air temperature, internal air humidity, and CO2 concentration. The air conditioning control unit 150 obtains information including the presence or absence of passengers and the number of passengers from the flight control unit 40, etc. In addition, the air conditioning control unit 150 can also obtain the internal air temperature, internal air humidity, and CO2 concentration from the flight control unit 40.

[0067] In step S102, the air-conditioning control unit 150 obtains the external environment information. The external environment information is information indicating the external environment of the eVTOL 10. The external environment of the eVTOL 10 is sometimes referred to as the external environment. The external environment information corresponds to the external environment information. Examples of the external environment information include the external air temperature and air pressure. The air-conditioning control unit 150 uses the detection signals of the external air sensor 165 and the air pressure sensor 166 to obtain the external air temperature, the external air quality, the odor of the external air, the air pressure, etc. Additionally, the air-conditioning control unit 150 can also obtain the external environment information from the flight control unit 40 or the like.

[0068] In step S103, the air-conditioning control unit 150 obtains the flight information. The flight information is information indicating the flight state of the eVTOL 10. Examples of the flight information include information related to the vertical takeoff and vertical landing, ascent and descent, altitude, climb, descent, and flight plan of the eVTOL 10. The air-conditioning control unit 150 obtains the flight information from the flight control unit 40 or the like.

[0069] In step S104, the air-conditioning control unit 150 performs a window fogging determination process. In the window fogging determination process, it is determined whether the window 16 fogs up. The fogging of the window 16 occurs due to condensation adhering to the window panel or the like. In the window 16, the window panel becomes a fogged state due to condensation adhering to it. In the window 16, it is possible for at least one of internal fogging and external fogging to occur. In internal fogging, fogging occurs on the inner side of the window 16. For example, in internal fogging, condensation adheres to the surface on the cabin 15 side of the window panel and causes fogging. In external fogging, fogging occurs on the outer side of the window 16. For example, in external fogging, condensation adheres to the surface on the external side of the window panel and causes fogging. The fogging of the window 16 is sometimes referred to as window fogging.

[0070] In the window fogging determination process, the air-conditioning control unit 150 determines whether the window 16 fogs up by determining whether the window fogging conditions are satisfied. The window fogging conditions are the conditions for causing the window 16 to fog up. In the window fogging determination process, each of the multiple window fogging conditions is determined individually. When at least one of the window fogging conditions is satisfied, the air-conditioning control unit 150 determines that the window 16 is likely to fog up. The air-conditioning control unit 150 determines the likelihood of window fogging by determining whether the window fogging conditions are satisfied. The function of the air-conditioning control unit 150 that executes the process of step S104 corresponds to the window fogging determination unit.

[0071] Refer to Figure 4The flowchart is used to illustrate the determination process of window fogging. In steps S201 - S204 of the window fogging determination process, the air - conditioner control unit 150 uses flight information to determine whether the window fogging condition is established. The function of the air - conditioner control unit 150 that executes the processes of steps S201 - S204 is equivalent to the flight determination unit.

[0072] In step S201, the air - conditioner control unit 150 uses flight information to determine whether the eVTOL 10 takes off vertically. When the eVTOL 10 takes off vertically, the air - conditioner control unit 150 determines that the window fogging condition is established. The vertical take - off of the eVTOL 10 is equivalent to the window fogging condition. As the case of the vertical take - off of the eVTOL 10, there are cases where the eVTOL 10 is in the preparation stage of vertical take - off, the eVTOL 10 is in the process of vertical take - off, etc. The function of the air - conditioner control unit 150 that executes the process of step S201 is equivalent to the take - off determination unit.

[0073] In step S202, the air - conditioner control unit 150 uses flight information to determine whether the eVTOL 10 lands vertically. When the eVTOL 10 lands vertically, the air - conditioner control unit 150 determines that the window fogging condition is established. The vertical landing of the eVTOL 10 is equivalent to the window fogging condition. As the case of the vertical landing of the eVTOL 10, there are cases where the eVTOL 10 is in the preparation stage of vertical landing, the eVTOL 10 is in the process of vertical landing, etc. The function of the air - conditioner control unit 150 that executes the process of step S202 is equivalent to the landing determination unit.

[0074] In step S203, the air - conditioner control unit 150 determines whether the flight altitude P1 is higher than the first determination value J1. The flight altitude P1 is the altitude at which the eVTOL 10 flies. The air - conditioner control unit 150 obtains the flight altitude P1 based on flight information. The flight altitude P1 is included in the flight information. The first determination value J1 is set to a value indicating the degree of altitude at which fogging occurs in the window 16. The first determination value J1 is set to, for example, several tens of meters to several hundreds of meters. The first determination value J1 is a value determined in advance through tests, etc., and is stored in the memory 152, etc.

[0075] When the flight altitude P1 is higher than the first determination value J1, the air conditioning control unit 150 proceeds to step S204. In step S204, the air conditioning control unit 150 determines whether the lift speed P2 is faster than the second determination value J2. The air conditioning control unit 150 obtains the lift speed P2 based on flight information such as lift information. The lift speed P2 is included in the flight information. The lift speed P2 is the speed at which the eVTOL 10 ascends or descends. The lift speed P2 is the distance that the eVTOL 10 moves in the vertical direction per unit time. As the lift speed P2, there is an ascending speed or a descending speed. The ascending speed is the speed at which the eVTOL 10 ascends. The descending speed is the speed at which the eVTOL 10 descends. The second determination value J2 is set to a value indicating that the lift speed P2 is fast enough to cause fogging on the window 16. The second determination value J2 is a value determined in advance through tests or the like and is stored in the memory 152 or the like.

[0076] When the flight altitude P1 is higher than the first determination value J1 and the lift speed P2 is faster than the second determination value J2, the air conditioning control unit 150 determines that the window fogging condition is satisfied. The condition that the flight altitude P1 is higher than the first determination value J1 and the lift speed P2 is faster than the second determination value J2 is equivalent to the window fogging condition. The flight altitude P1 and the lift speed P2 are parameters related to the window fogging condition and are equivalent to window fogging parameters. The first determination value J1 and the second determination value J2 are determination values used to determine whether the window fogging condition is satisfied and are equivalent to window fogging determination values.

[0077] The air conditioning control unit 150 compares the flight altitude P1 with the first determination value J1. The determination result of whether the flight altitude P1 is higher than the first determination value J1 is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The air conditioning control unit 150 compares the lift speed P2 with the second determination value J2. The determination result of whether the lift speed P2 is faster than the second determination value J2 is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air conditioning control unit 150 that executes the processes of steps S203 and S204 is equivalent to a parameter determination unit.

[0078] When the window fogging condition is satisfied in steps S201 to S204, the air conditioning control unit 150 proceeds to step S214 to perform condition satisfaction processing. In the condition satisfaction processing, it is stored in the memory 152 or the like that the window fogging condition is satisfied. For example, the air conditioning control unit 150 sets a condition satisfaction flag indicating that the window fogging condition is satisfied in the memory 152 or the like. In addition, the air conditioning control unit 150 clears the condition non-satisfaction flag described later.

[0079] In addition, the air-conditioning control unit 150 may also determine whether the window fogging condition is satisfied for each of steps S203 and S204 individually. For example, when the flight altitude P1 is higher than the first determination value J1 in step S203, the air-conditioning control unit 150 determines that the window fogging condition is satisfied and performs the condition-satisfied process in step S214. In addition, when the lift-off speed P2 is faster than the second determination value J2 in step S204, the air-conditioning control unit 150 determines that the window fogging condition is satisfied and performs the condition-satisfied process in step S214.

[0080] For step S201, when the eVTOL 10 takes off vertically, the air-conditioning control unit 150 performs the condition-satisfied process in step S214. For step S202, when the eVTOL 10 lands vertically, the air-conditioning control unit 150 performs the condition-satisfied process in step S214. For steps S203 and S204, when the flight altitude P1 is higher than the first determination value J1 and the lift-off speed P2 is faster than the second determination value J2, the air-conditioning control unit 150 performs the condition-satisfied process in step S214.

[0081] When the window fogging condition is not satisfied in steps S201 to S204, the air-conditioning control unit 150 determines whether the window fogging condition is satisfied by using the external environment information in steps S205 and S206. The function of the air-conditioning control unit 150 that executes the processes of steps S205 and S206 is equivalent to the external determination unit.

[0082] In step S205, the air-conditioning control unit 150 determines whether the air pressure change speed P3 is faster than the third determination value J3. When the eVTOL 10 is moving while flying, the air pressure outside the eVTOL 10 sometimes changes as the eVTOL 10 moves. The air pressure change speed P3 is the speed at which the air pressure outside the eVTOL 10 changes. For example, the air pressure change speed P3 is the amount of change in the air pressure outside the eVTOL 10 per unit time. The air-conditioning control unit 150 obtains the air pressure from the external environment information and calculates the air pressure change speed P3 by using the air pressure. The air pressure change speed P3 is included in the external environment information. The third determination value J3 is set to a value indicating that the air pressure changes to a degree that causes fogging in the window 16 in a short time. In other words, the third determination value J3 is set to the value indicated by the air pressure change speed P3, that is, the value at which the flight altitude P1 changes to a degree that causes fogging in the window 16 in a short time. The third determination value J3 is a value determined in advance through experiments or the like and is stored in the memory 152 or the like.

[0083] When the air pressure change speed P3 is faster than the third determination value J3, the air conditioner control unit 150 determines that the window fogging condition is established. The air pressure change speed P3 being faster than the third determination value J3 is equivalent to the window fogging condition. The air pressure change speed P3 is a parameter associated with the window fogging condition and is equivalent to the window fogging parameter. The third determination value J3 is a determination value used to determine whether the window fogging condition is established and is equivalent to the window fogging determination value. The air conditioner control unit 150 compares the air pressure change speed P3 with the third determination value J3. The determination result of whether the air pressure change speed P3 is faster than the third determination value J3 is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air conditioner control unit 150 that executes the process of step S205 is equivalent to the parameter determination unit.

[0084] In step S206, the air conditioner control unit 150 determines whether the outside air temperature change speed P4 is faster than the fourth determination value J4. When the eVTOL 10 is flying and moving, the outside air temperature sometimes changes as the eVTOL 10 moves. The outside air temperature change speed P4 is the speed at which the outside air temperature outside the eVTOL 10 changes. For example, the outside air temperature change speed P4 is the amount of change in the outside air temperature outside the eVTOL 10 per unit time. The air conditioner control unit 150 obtains the outside air temperature from the outside environment information and uses this outside air temperature to calculate the outside air temperature change speed P4. The outside air temperature change speed P4 is included in the outside environment information. The fourth determination value J4 is set to a value indicating that the outside air temperature changes to a degree that causes fogging in the window 16 in a short time. In other words, the fourth determination value J4 is set to the value indicated by the outside air temperature change speed P4, that is, the value at which the flight altitude P1 changes to a degree that causes fogging in the window 16 in a short time. The fourth determination value J4 is a value determined in advance through experiments and is stored in the memory 152 or the like.

[0085] When the outside air temperature change speed P4 is faster than the fourth determination value J4, the air conditioner control unit 150 determines that the window fogging condition is established. The outside air temperature change speed P4 being faster than the fourth determination value J4 is equivalent to the window fogging condition. The outside air temperature change speed P4 is a parameter associated with the window fogging condition and is equivalent to the window fogging parameter. The fourth determination value J4 is a determination value used to determine whether the window fogging condition is established and is equivalent to the window fogging determination value. The air conditioner control unit 150 compares the outside air temperature change speed P4 with the fourth determination value J4. The determination result of whether the outside air temperature change speed P4 is faster than the fourth determination value J4 is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air conditioner control unit 150 that executes the process of step S206 is equivalent to the parameter determination unit.

[0086] When the window fogging condition is satisfied in steps S205 and S206, the air conditioner control unit 150 performs the condition satisfaction process in step S214. For example, when the air pressure change rate P3 is faster than the third determination value J3 in step S205, the air conditioner control unit 150 performs the condition satisfaction process in step S214. When the outside air temperature change rate P4 is faster than the fourth determination value J4 in step S206, the air conditioner control unit 150 performs the condition satisfaction process in step S214.

[0087] When the window fogging condition is not satisfied in steps S201 to S206, the air conditioner control unit 150 determines whether the window fogging condition is satisfied using the in-vehicle environment information in steps S207 to S210. The function of the air conditioner control unit 150 that executes the processes of steps S207 to S210 is equivalent to an internal determination unit.

[0088] In step S207, the air conditioner control unit 150 determines whether the internal air humidity P5 is higher than the fifth determination value J5. The air conditioner control unit 150 obtains the internal air humidity P5 from the in-vehicle environment information. The internal air humidity P5 is included in the in-vehicle environment information. The fifth determination value J5 is set to a value indicating that the internal air humidity P5 is high enough to cause fogging in the window 16. The fifth determination value J5 is a value determined in advance through tests or the like and is stored in the memory 152 or the like.

[0089] When the internal air humidity P5 is higher than the fifth determination value J5, the air conditioner control unit 150 determines that the window fogging condition is satisfied. The internal air humidity P5 being higher than the fifth determination value J5 is equivalent to the window fogging condition. The internal air humidity P5 is a parameter associated with the window fogging condition and is equivalent to the window fogging parameter. The fifth determination value J5 is a determination value for determining whether the window fogging condition is satisfied and is equivalent to the window fogging determination value. The air conditioner control unit 150 compares the internal air humidity P5 with the fifth determination value J5. The determination result of whether the internal air humidity P5 is higher than the fifth determination value J5 is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air conditioner control unit 150 that executes the process of step S207 is equivalent to a parameter determination unit.

[0090] In step S208, the air-conditioning control unit 150 determines whether the CO2 concentration P6 is higher than the sixth determination value J6. The air-conditioning control unit 150 obtains the CO2 concentration P6 from the in-vehicle environment information. The CO2 concentration P6 is included in the in-vehicle environment information. In the eVTOL 10, if the external air introduced into the cabin 15 is insufficient, the CO2 concentration P6 tends to increase. In addition, if the introduction into the cabin 15 is insufficient, fogging of the window 16 is likely to occur. Therefore, it can be said that the higher the CO2 concentration P6, the more likely fogging of the window 16 is to occur. The sixth determination value J6 is set to a value indicating that the CO2 concentration P6 is high enough to cause fogging in the window 16. The sixth determination value J6 is also a value indicating that the external air introduced into the cabin 15 is insufficient to the extent that fogging occurs in the window. The sixth determination value J6 is a value determined in advance through tests or the like and is stored in the memory 152 or the like.

[0091] When the CO2 concentration P6 is higher than the sixth determination value J6, the air-conditioning control unit 150 determines that the window fogging condition is satisfied. The CO2 concentration P6 being higher than the sixth determination value J6 is equivalent to the window fogging condition. The CO2 concentration P6 is a parameter associated with the window fogging condition and is equivalent to the window fogging parameter. The sixth determination value J6 is a determination value used to determine whether the window fogging condition is satisfied and is equivalent to the window fogging determination value. The air-conditioning control unit 150 compares the CO2 concentration P6 with the sixth determination value J6. The determination result of whether the CO2 concentration P6 is higher than the sixth determination value J6 is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air-conditioning control unit 150 that executes the process of step S208 is equivalent to the parameter determination unit.

[0092] In step S209, the air-conditioning control unit 150 determines whether a passenger is on board the eVTOL 10. When a passenger is on board the eVTOL 10, the air-conditioning control unit 150 proceeds to step S210. In step S210, the air-conditioning control unit 150 determines whether the internal air duration P7 is longer than the seventh determination value J7. The internal air duration P7 is the time during which the air-conditioning system 110 continuously performs internal air circulation. The internal air duration P7 is the duration during which the intake switching unit 127 is in the internal air state. In the eVTOL 10, if the time for internal air circulation without external air introduction is long, fogging of the window 16 is likely to occur due to the exhalation of the passenger or the like. The seventh determination value J7 is set to a value indicating that the internal air duration P7 is long enough to cause fogging in the window 16. The seventh determination value J7 is a value determined in advance through tests or the like and is stored in the memory 152 or the like.

[0093] When the occupant is in the eVTOL 10 and the internal air duration P7 is longer than the seventh determination value J7, the air-conditioning control unit 150 determines that the window fogging condition is satisfied. The occupant being in the eVTOL 10 and the internal air duration P7 being longer than the seventh determination value J7 is equivalent to the window fogging condition. The internal air duration P7 is a parameter associated with the window fogging condition and is equivalent to the window fogging parameter. The seventh determination value J7 is a determination value used to determine whether the window fogging condition is satisfied and is equivalent to the window fogging determination value. The air-conditioning control unit 150 compares the internal air duration P7 and the seventh determination value J7. The determination result of whether the internal air duration P7 is longer than the seventh determination value J7 is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air-conditioning control unit 150 that performs the processes of steps S209 and S210 is equivalent to the parameter determination unit.

[0094] When the window fogging condition is satisfied in steps S207 to S210, the air-conditioning control unit 150 performs the condition-satisfied process in step S214. For example, when the internal air humidity P5 is higher than the fifth determination value J5 in step S207, the air-conditioning control unit 150 performs the condition-satisfied process in step S214. When the CO2 concentration P6 is higher than the sixth determination value J6 in step S208, the air-conditioning control unit 150 performs the condition-satisfied process in step S214. For steps S209 and S210, when the passenger is in the eVTOL 10 and the internal air duration P7 is longer than the seventh determination value J7, the air-conditioning control unit 150 performs the condition-satisfied process in step S214.

[0095] In addition, the air-conditioning control unit 150 can also determine whether the window fogging condition is satisfied individually for each of steps S209 and S210. For example, for step S209, when the occupant is in the eVTOL 10, the air-conditioning control unit 150 determines that the window fogging condition is satisfied and performs the condition-satisfied process in step S214. The air-conditioning control unit 150 can also determine whether the number of occupants is more than the specified number, and when the number of occupants is more than the specified number, it determines that the window fogging condition is satisfied. The number of occupants is sometimes referred to as the number of passengers. In addition, when the internal air duration P7 is longer than the seventh determination value J7 in step S210, the air-conditioning control unit 150 determines that the window fogging condition is satisfied and performs the condition-satisfied process in step S214.

[0096] When the window fogging condition does not hold in steps S201 to S210, the air-conditioning control unit 150 proceeds to step S211 to obtain the internal-external difference P8a. The internal-external difference P8a is the difference between the internal air temperature and the external air temperature. The air-conditioning control unit 150 obtains the internal air temperature and the external air temperature based on the in-cabin environment information and the out-of-cabin environment information, and uses these internal air temperature and external air temperature to calculate the internal-external difference P8a.

[0097] In step S212, the air-conditioning control unit 150 determines whether the internal-external difference change speed P8 is faster than the eighth determination value J8. When the eVTOL 10 is flying and moving, due to the change of the external air temperature as the eVTOL 10 moves, etc., the internal-external difference P8a sometimes changes as the eVTOL 10 moves. The internal-external difference change speed P8 is the speed at which the internal-external difference P8a changes. For example, the internal-external difference change speed P8 is the change amount of the internal-external difference P8a per unit time. The air-conditioning control unit 150 uses the internal-external difference P8a to calculate the internal-external difference change speed P8. In the eVTOL 10, if the internal-external difference P8a increases or decreases within a short time, it is easy to cause fogging of the window 16. For example, when the eVTOL 10 rises within a short time and the external air temperature relatively decreases with respect to the internal air temperature within a short time, internal fogging of the window 16 is likely to occur. The eighth determination value J8 is set to a value indicating the degree to which the internal-external difference change speed P8 is fast enough to cause fogging in the window 16. The eighth determination value J8 is a value determined in advance through experiments, etc., and is stored in the memory 152, etc.

[0098] When the internal-external difference change speed P8 is higher than the eighth determination value J8, the air-conditioning control unit 150 determines that the window fogging condition holds. The internal-external difference change speed P8 being higher than the eighth determination value J8 is equivalent to the window fogging condition. The internal-external difference change speed P8 is a parameter associated with the window fogging condition and is equivalent to the window fogging parameter. The eighth determination value J8 is a determination value used to determine whether the window fogging condition holds and is equivalent to the window fogging determination value. The air-conditioning control unit 150 compares the internal-external difference change speed P8 and the eighth determination value J8. The determination result of whether the internal-external difference change speed P8 is faster than the eighth determination value J8 is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air-conditioning control unit 150 that executes the process of step S212 is equivalent to the parameter determination unit.

[0099] The internal-external difference change speed P8 is included in the internal-external difference information indicating the change mode of the internal-external difference P8a. The air conditioner control unit 150 uses internal-external difference information such as the internal-external difference change speed P8 to determine whether the window fogging condition is satisfied. As the internal-external difference information, in addition to the internal-external difference change speed P8, there is also the change amount of the internal-external difference P8a within a specified time, etc. The function of the air conditioner control unit 150 that executes the process of step S212 is equivalent to the internal-external determination unit.

[0100] When the window fogging condition is satisfied in step S212, the air conditioner control unit 150 performs the condition-satisfied process in step S214. For example, when the internal-external difference change speed P8 is greater than the eighth determination value J8 in step S212, the air conditioner control unit 150 performs the condition-satisfied process in step S214.

[0101] When the window fogging condition is not satisfied in steps S201 to S212, the air conditioner control unit 150 proceeds to step S213. The air conditioner control unit 150 performs the condition-not-satisfied process in step S213. In the condition-not-satisfied process, it is stored in the memory 152 or the like that the window fogging condition is not satisfied. For example, the air conditioner control unit 150 sets a condition-not-satisfied flag indicating that the window fogging condition is not satisfied in the memory 152 or the like. In addition, the air conditioner control unit 150 clears the condition-satisfied flag.

[0102] Return to Figure 3 , after the window fogging determination process in step S104, the air conditioner control unit 150 proceeds to step S105. The air conditioner control unit 150 determines whether the window 16 is fogged in step S105. That is, the air conditioner control unit 150 determines whether the window fogging condition is satisfied in the window fogging determination process. For example, the air conditioner control unit 150 determines whether either the condition-satisfied flag or the condition-not-satisfied flag is set. When the condition-not-satisfied flag is set, the air conditioner control unit 150 determines that the window fogging condition is not satisfied. When the window fogging condition is not satisfied, the air conditioner control unit 150 assumes that the window 16 is not likely to be fogged and proceeds to step S107.

[0103] The air-conditioning control unit 150 performs internal air mode processing in step S107. In the internal air mode processing, the operation mode of the air-conditioning system 110 is set to the internal air mode. The operation mode is the operation method of the air-conditioning system 110. The internal air mode is an operation mode in which the air-conditioning system 110 performs internal air circulation. The internal air mode is sometimes referred to as the in-cabin circulation mode. The internal air mode is one of the internal air circulation functions of the air-conditioning system 110 for circulating internal air inside the eVTOL 10. In the internal air mode, the internal air including the inhaled internal air Air1 circulates in the cabin 15 and the air-conditioning system 110. That is, in the internal air mode, the internal air circulates inside the eVTOL 10. In the internal air mode, the intake switching unit 127 is set to the internal air state. In the internal air mode, the state of stopping the introduction of external air is established.

[0104] After step S107, the air-conditioning control unit 150 proceeds to step S109 and performs notification processing. In the notification processing, the operation mode of the air-conditioning system 110 is notified. In the notification processing, the operation mode is notified to the pilot or the passenger through an image, sound, etc. For example, when the operation mode is set to the internal air mode in step S107, the air-conditioning control unit 150 notifies through the notification processing that the operation mode is the internal air mode.

[0105] For step S105, when the condition establishment flag is set, the air-conditioning control unit 150 determines that the window fogging condition is established. When the window fogging condition is established, the air-conditioning control unit 150 assumes that the window 16 is likely to fog and proceeds to step S106. The air-conditioning control unit 150 determines whether the external air is normal in step S106. For example, the air-conditioning control unit 150 determines whether the external air quality or the smell of the external air is within the normal range. The air-conditioning control unit 150 determines that the external air is normal when the external air quality and the smell of the external air are within the normal range. For example, when the concentration of pollutants is low enough, the air-conditioning control unit 150 determines that the external air is not polluted air and the external air quality is within the normal range.

[0106] When fogging is likely to occur on the window 16 and the outside air is normal, the air-conditioning control unit 150 proceeds to step S108 to perform outside air mode processing. In the outside air mode processing, the operation mode of the air-conditioning system 110 is set to the outside air mode. The outside air mode is an operation mode in which the air-conditioning system 110 is used to introduce outside air. The outside air mode is sometimes referred to as the outside air introduction mode. The outside air mode is one of the outside air introduction functions of the air-conditioning system 110 for introducing outside air into the interior of the eVTOL 10. In the outside air mode, the inhaled outside air Air2 is introduced into the cabin 15. That is, in the outside air mode, outside air is introduced into the interior of the eVTOL 10. In the outside air mode, the intake switching unit 127 is set to the outside air state. In the outside air mode, the state of stopping the internal air circulation is maintained.

[0107] For example, when the operation mode is switched from the internal air mode to the outside air mode, the air-conditioning control unit 150 switches the intake switching unit 127 from the internal air state to the outside air state. In this case, the inhaled outside air Air2 introduced into the cabin 15 increases. The function of the air-conditioning control unit 150 that executes the process of step S108 is equivalent to the outside air increase unit and the outside air mode unit.

[0108] When fogging is likely to occur on the window 16, the window 16 is less likely to fog by introducing outside air. In addition, when fogging occurs on the window 16, the fog on the window 16 is easily eliminated by introducing outside air. For example, when the internal air humidity P5 is higher than the fifth determination value J5, by using outside air introduction to make the internal air humidity P5 lower than the fifth determination value J5, window fogging can be suppressed. In addition, when the CO2 concentration P6 is higher than the sixth determination value J6, by using outside air introduction to reduce the CO2 concentration P6 and reduce the internal air humidity P5, etc., window fogging can be suppressed. In addition, when the occupants are in the eVTOL 10 and the internal air duration P7 is longer than the seventh determination value J7, by using outside air introduction to reduce the internal air humidity P5, etc., window fogging can be suppressed.

[0109] In the eVTOL 10, it is considered that the temperature difference between the inside and outside of the fuselage is the main cause of window fogging. In the present embodiment, as parameters related to the temperature difference between the inside and outside of the fuselage, the flight altitude P1, the lift / drop speed P2, the air pressure change speed P3, the outside air temperature change speed P4, the internal-external difference P8a, the internal-external difference change speed P8, etc. are used. Even when window fogging occurs due to the temperature difference between the inside and outside of the fuselage, window fogging can be suppressed by introducing outside air.

[0110] For example, when the change speed P8 of the internal-external difference is faster than the eighth determination value J8, by using the external air introduction to make the change speed P8 of the internal-external difference slower than the eighth determination value J8, window fogging can be suppressed. In addition, when the eVTOL 10 performs vertical takeoff or vertical landing, by using the external air introduction to reduce the change speed P8 of the internal-external difference, etc., window fogging can be suppressed. Even when the flight altitude P1 is higher than the first determination value J1 and the lifting speed P2 is faster than the second determination value J2, by using the external air introduction to reduce the change speed P8 of the internal-external difference, etc., window fogging can also be suppressed. When the air pressure change speed P3 is faster than the third determination value J3 and the external air temperature change speed P4 is faster than the fourth determination value J4, by using the external air introduction to reduce the change speed P8 of the internal-external difference, etc., window fogging can be suppressed.

[0111] It is considered that when the eVTOL 10 performs vertical takeoff, as the eVTOL 10 rises in a short time, the change speed P8 of the internal-external difference becomes faster, etc., and window fogging is likely to occur. In response to this, when the eVTOL 10 performs vertical takeoff, even if the flight altitude P1 rapidly increases, due to the external air introduction, the change speed P8 of the internal-external difference becomes slower, etc., and window fogging can be suppressed. In addition, it is considered that when the eVTOL 10 performs vertical landing, as the eVTOL 10 descends in a short time, the change speed P8 of the internal-external difference becomes faster, etc., and window fogging is likely to occur. In response to this, when the eVTOL 10 performs vertical landing, even if the flight altitude P1 rapidly decreases, due to the external air introduction, the change speed P8 of the internal-external difference becomes slower, etc., and window fogging can be suppressed.

[0112] The air-conditioning control unit 150 proceeds to step S109 after step S108 and performs a notification process. For example, when the operation mode is set to the external air mode, the air-conditioning control unit 150 notifies that the operation mode is the external air mode through the notification process.

[0113] Regarding steps S105 and S106, when window fogging is likely to occur in the window 16 and the external air is abnormal, the air-conditioning control unit 150 proceeds to step S107 and performs the internal air mode process. In this case, compared with suppressing window fogging, restricting the introduction of polluted air into the cabin 15 is prioritized. The air-conditioning control unit 150 restricts the introduction of pollutants into the cabin 15 together with the external air. After that, the air-conditioning control unit 150 proceeds to step S107 and performs the internal air mode process. In this internal air mode process, it is notified that window fogging is likely to occur in the window 16, external air introduction is not performed, the external air is abnormal, etc.

[0114] According to the embodiment described so far, when the window fogging condition in the eVTOL 10 is satisfied, the intake of outside air Air2 introduced into the interior of the eVTOL 10 increases. In this configuration, it is possible to suppress fogging from occurring on the window 16 of the eVTOL 10 by introducing the outside air Air2. Further, even if fogging occurs on the window 16 of the eVTOL 10, the fogging can be reduced by introducing the outside air Air2. Therefore, even if a dedicated device for heating the window 16 or the like is not provided in the eVTOL 10, the visibility of the pilot can be prevented from deteriorating due to fogging of the window 16 by using the outside air introduction function of the air conditioning system 110. Thus, the safety of the eVTOL 10 can be improved in the air conditioning system 110, the air conditioning control unit 150, and the program 153.

[0115] According to the present embodiment, by switching the operation mode of the air conditioning system 110 from the internal air mode to the outside air mode, the intake of outside air Air2 introduced into the interior of the eVTOL 10 increases. In this configuration, fogging of the window 16 can be suppressed by using the outside air mode as one of the outside air introduction functions. Further, in the outside air mode, since the amount of the intake of outside air Air2 introduced into the cabin 15 can be sufficiently ensured, even if fogging of the window occurs, the fogging of the window can be quickly eliminated.

[0116] According to the present embodiment, in the determination of whether the window fogging condition is satisfied, flight information such as the flight altitude P1, in-cabin environment information such as the internal air humidity P5, and out-of-cabin environment information such as the outside air temperature change rate P4 are used. Therefore, when the flight state of the eVTOL 10 affects the likelihood of window fogging, the accuracy of predicting the occurrence of window fogging can be improved by the flight information. Further, when the in-cabin environment of the eVTOL 10 affects the likelihood of window fogging, the accuracy of predicting the occurrence of window fogging can be improved by the in-cabin environment information. In addition, when the out-of-cabin environment of the eVTOL 10 affects the likelihood of window fogging, the accuracy of predicting the occurrence of window fogging can be improved by the out-of-cabin environment information. Therefore, it is possible to suppress a situation where outside air is not introduced even though window fogging is likely to occur by using the flight information, the in-cabin environment information, and the out-of-cabin environment information.

[0117] According to the present embodiment, in the determination of whether the window fogging condition is satisfied, inside-outside difference information such as the inside-outside difference change rate P8 is used. Therefore, when the change pattern of the inside-outside difference P8a is likely to affect the ease of occurrence of window fogging, the accuracy of predicting the occurrence of window fogging can be improved by the inside-outside difference information. Therefore, it is possible to suppress a situation where outside air is not introduced even though window fogging is likely to occur by using the inside-outside difference information.

[0118] According to the present embodiment, the air-conditioning control unit 150 determines that the window fogging condition is satisfied by the vertical takeoff of the eVTOL 10. In this configuration, outside air is introduced when the eVTOL 10 takes off vertically. Therefore, it is possible to suppress the window from fogging due to, for example, the change speed P8 of the internal and external difference becoming faster with the vertical takeoff of the eVTOL 10 through the introduction of outside air. Therefore, when the eVTOL 10 takes off vertically, it is possible to reliably suppress the situation where the pilot's visibility is deteriorated due to window fogging.

[0119] According to the present embodiment, the air-conditioning control unit 150 determines that the window fogging condition is satisfied by the vertical landing of the eVTOL 10. In this configuration, outside air is introduced when the eVTOL 10 lands vertically. Therefore, it is possible to suppress the window from fogging due to, for example, the change speed P8 of the internal and external difference becoming faster with the vertical landing of the eVTOL 10 through the introduction of outside air. Therefore, when the eVTOL 10 lands vertically, it is possible to reliably suppress the situation where the pilot's visibility is deteriorated due to window fogging.

[0120] According to the present embodiment, the air-conditioning control unit 150 determines whether the window fogging condition is satisfied by using the comparison result between window fogging parameters such as the outside air temperature change speed P4 and window fogging determination values such as the fourth determination value J4. In this configuration, by setting the window fogging determination value to a value with good accuracy through experiments or the like, it is possible to improve the accuracy of the comparison result between the window fogging parameter and the window fogging determination value. Therefore, it is possible to improve the determination accuracy of whether the window fogging condition is satisfied by the window fogging determination value. Therefore, it is possible to suppress the situation where the window is likely to fog but outside air is not introduced by the window fogging parameter and the window fogging determination value.

[0121] <Second Embodiment> In the above first embodiment, the pre-determined first determination value J1 and the like are used as parameter determination values for determining the window fogging condition. In contrast, in the second embodiment, the corrected value obtained by correcting the first determination value J1 and the like is used as the parameter determination value for determining the window fogging condition. The structures, operations, and effects not specifically described in the second embodiment are the same as those in the first embodiment above. In the second embodiment, the description will be centered on the points different from the first embodiment above.

[0122] The air-conditioning control unit 150 performs air-conditioning control processing in the same manner as in the first embodiment above. In the present embodiment, the air-conditioning control processing will be described with reference to Figure 5 the flowchart. The air-conditioning control unit 150 obtains in-cabin environment information, outside-cabin environment information, and flight information in steps S101 to S103 in the same manner as in the first embodiment above.

[0123] The air conditioner control unit 150 performs determination value correction processing in Figure 5 the determination value correction processing in step S301 shown below. The air conditioner control unit 150 corrects the reference determination value as the determination value correction processing. The reference determination value is a value associated with the window fogging condition. The reference determination value is a value determined in advance through tests or the like and is stored in the memory 152 or the like. For example, the reference determination values are the first determination value J1 to the eighth determination value J8. The air conditioner control unit 150 corrects the reference determination value using correction parameters. As the correction parameters, there are internal and external difference information, the number of occupants, outside environment information, and the like. The air conditioner control unit 150 obtains the first corrected value J1c to the eighth corrected value J8c by correcting the first determination value J1 to the eighth determination value J8. In the present embodiment, the corrected values J1c to J8c are window fogging determination values. The function of the air conditioner control unit 150 that executes the processing of step S301 is equivalent to the determination value correction unit.

[0124] Refer to Figure 6 the flowchart shown below to explain the determination value correction processing. The air conditioner control unit 150 obtains the pre-takeoff internal and external difference P8b in step S401. The pre-takeoff internal and external difference P8b is the temperature difference between the internal air and the external air before the eVTOL 10 takes off. That is, the pre-takeoff internal and external difference P8b is the pre-takeoff internal and external difference P8a. For example, the pre-takeoff internal and external difference P8b is the pre-takeoff internal and external difference P8a immediately before takeoff, the pre-takeoff internal and external difference P8a during takeoff preparation. The pre-takeoff internal and external difference P8b is equivalent to the temperature difference, and the pre-takeoff internal and external difference P8b is equivalent to the correction parameter.

[0125] The air conditioner control unit 150 corrects the determination values J1 to J8 using the pre-takeoff internal and external difference P8b in step S402. The air conditioner control unit 150 corrects the determination values J1 to J8 such that the smaller the pre-takeoff internal and external difference P8b, the more likely the external air introduction method is selected. In the eVTOL 10, the smaller the pre-takeoff internal and external difference P8b, the easier the internal and external difference change speed P8 becomes larger after takeoff. For example, before the eVTOL 10 takes off, when the internal air temperature is higher than the external air temperature and the pre-takeoff internal and external difference P8b is small, as the eVTOL 10 takes off, the external air temperature decreases, and the internal and external difference change speed P8 becomes larger. Thus, if the pre-takeoff internal and external difference P8b is small, the internal and external difference change speed P8 becomes larger or the like, and window fogging is likely to occur. Therefore, the air conditioner control unit 150 corrects the determination values J1 to J8 such that the smaller the pre-takeoff internal and external difference P8b, the smaller the corrected values J1c to J8c become. The function of the air conditioner control unit 150 that executes the processing of step S402 is equivalent to the temperature correction unit.

[0126] In addition, the air-conditioning control unit 150 may correct the determination values J1 to J8 in such a way that the greater the pre-takeoff inside-outside difference P8b, the more likely it is to select the outside air introduction. For example, the air-conditioning control unit 150 corrects the determination values J1 to J8 in such a way that the greater the pre-takeoff inside-outside difference P8b, the smaller the correction values J1c to J8c become.

[0127] The air-conditioning control unit 150 obtains the number of occupants in step S403. The number of occupants serves as a correction parameter. The air-conditioning control unit 150 uses the number of occupants to correct the determination values J1 to J8 in step S404. The air-conditioning control unit 150 corrects the determination values J1 to J8 in such a way that the greater the number of occupants, the more likely it is to select the outside air introduction. In the eVTOL 10, the more occupants there are, the more likely it is for the window to fog up due to exhalation or the like. The air-conditioning control unit 150 corrects the determination values J1 to J8 in such a way that the greater the number of occupants, the smaller the correction values J1c to J8c become. The function of the air-conditioning control unit 150 that executes the process of step S404 corresponds to an occupant correction unit.

[0128] The air-conditioning control unit 150 obtains the outside environment information in step S405. The outside environment information includes outside air quality information indicating the outside air quality. The air-conditioning control unit 150 obtains at least the outside air quality information included in the outside environment information.

[0129] The air-conditioning control unit 150 uses the outside environment information to correct the determination values J1 to J8 in step S406. The air-conditioning control unit 150 corrects the determination values J1 to J8 in such a way that the worse the outside air quality, the less likely it is to select the outside air introduction. When outside air in a state of poor outside air quality is introduced into the cabin 15, it is less likely for the window to fog up. On the other hand, there may be other adverse conditions different from window fogging due to the poor outside air quality. As other adverse conditions, there are cases where the occupants feel discomfort due to the polluted outside air, or the occupants experience physical discomfort due to the polluted outside air. Therefore, the air-conditioning control unit 150 corrects the determination values J1 to J8 in such a way that the worse the air quality, the greater the correction values J1c to J8c become. The function of the air-conditioning control unit 150 that executes the process of S406 corresponds to an outside air correction unit.

[0130] Return to Figure 5, after the determination value correction process in step S301, the air conditioner control unit 150 proceeds to step S302. The air conditioner control unit 150 performs a window fogging determination process in step S302. In the window fogging determination process of the present embodiment, different from the window fogging determination process of the first embodiment described above, the corrected values J1c to J8c are used as the window fogging determination values. Except for using the corrected values J1c to J8c as the window fogging determination values, in the window fogging determination process of the present embodiment, the same process as the window fogging determination process of the first embodiment described above is basically performed. The function of the air conditioner control unit 150 that executes the process of step S302 is equivalent to the window fogging determination unit. In addition, after the window fogging determination process in step S302 by the air conditioner control unit 150, the processes of steps S105 to S109 are performed.

[0131] Refer to Figure 7 the flowchart of to describe the window fogging determination process. The air conditioner control unit 150 performs the processes of steps S501 to S514 in the window fogging determination process. In steps S501 to S514, the same processes as steps S201 to S214 of the first embodiment described above are basically performed.

[0132] In steps S501 to S504, the air conditioner control unit 150 uses flight information to determine whether the window fogging condition is satisfied. The function of the air conditioner control unit 150 that executes the processes of steps S501 to S504 is equivalent to the flight determination unit. The air conditioner control unit 150 performs a vertical takeoff determination in step S501 and a vertical landing determination in step S502. The function of the air conditioner control unit 150 that executes the process of step S501 is equivalent to the takeoff determination unit. The function of the air conditioner control unit 150 that executes the process of step S502 is equivalent to the landing determination unit.

[0133] In step S503, the air conditioner control unit 150 determines whether the flight altitude P1 is higher than the first corrected value J1c. In step S504, the air conditioner control unit 150 determines whether the vertical speed P2 is faster than the second corrected value J2c. When the flight altitude P1 is higher than the first corrected value J1c and the vertical speed P2 is faster than the second corrected value J2c, the air conditioner control unit 150 determines that the window fogging condition is satisfied. The flight altitude P1 being higher than the first corrected value J1c and the vertical speed P2 being faster than the second corrected value J2c is equivalent to the window fogging condition. The first corrected value J1c and the second corrected value J2c are determination values for determining whether the window fogging condition is satisfied, and are equivalent to the window fogging determination values.

[0134] The air-conditioning control unit 150 compares the flight altitude P1 with the first correction value J1c. The determination result of whether the flight altitude P1 is higher than the first correction value J1c is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The air-conditioning control unit 150 compares the lifting speed P2 with the second correction value J2c. The determination result of whether the lifting speed P2 is faster than the second correction value J2c is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air-conditioning control unit 150 that executes the processes of steps S503 and S504 is equivalent to the parameter determination unit.

[0135] In steps S505 and S506, the air-conditioning control unit 150 uses the external environment information to determine whether the window fogging condition is established. The function of the air-conditioning control unit 150 that executes the processes of steps S505 and S506 is equivalent to the external determination unit.

[0136] In step S505, the air-conditioning control unit 150 determines whether the air pressure change rate P3 is faster than the third correction value J3c. When the air pressure change rate P3 is faster than the third correction value J3c, the air-conditioning control unit 150 determines that the window fogging condition is established. The air pressure change rate P3 being faster than the third correction value J3c is equivalent to the window fogging condition. The third correction value J3c is a determination value used to determine whether the window fogging condition is established and is equivalent to the window fogging determination value. The air-conditioning control unit 150 compares the air pressure change rate P3 with the third correction value J3c. The determination result of whether the air pressure change rate P3 is faster than the third correction value J3c is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air-conditioning control unit 150 that executes the process of step S505 is equivalent to the parameter determination unit.

[0137] In step S506, the air-conditioning control unit 150 determines whether the external air temperature change rate P4 is faster than the fourth correction value J4c. When the external air temperature change rate P4 is faster than the fourth correction value J4c, the air-conditioning control unit 150 determines that the window fogging condition is established. The external air temperature change rate P4 being faster than the fourth correction value J4c is equivalent to the window fogging condition. The fourth correction value J4c is a determination value used to determine whether the window fogging condition is established and is equivalent to the window fogging determination value. The air-conditioning control unit 150 compares the external air temperature change rate P4 with the fourth correction value J4c. The determination result of whether the external air temperature change rate P4 is faster than the fourth correction value J4c is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air-conditioning control unit 150 that executes the process of step S506 is equivalent to the parameter determination unit.

[0138] In steps S507 to S510, the air conditioner control unit 150 determines whether the window fogging condition is satisfied using the in-vehicle environment information. The function for performing the processes of steps S507 to S510 in the air conditioner control unit 150 corresponds to the internal determination unit.

[0139] In step S507, the air conditioner control unit 150 determines whether the internal air humidity P5 is higher than the fifth correction value J5c. When the internal air humidity P5 is higher than the fifth correction value J5c, the air conditioner control unit 150 determines that the window fogging condition is satisfied. The internal air humidity P5 being higher than the fifth correction value J5c corresponds to the window fogging condition. The fifth correction value J5c is a determination value for determining whether the window fogging condition is satisfied and corresponds to the window fogging determination value. The air conditioner control unit 150 compares the internal air humidity P5 with the fifth correction value J5c. The determination result of whether the internal air humidity P5 is higher than the fifth correction value J5c corresponds to the comparison result between the window fogging parameter and the window fogging determination value. The function for performing the process of step S507 in the air conditioner control unit 150 corresponds to the parameter determination unit.

[0140] In step S508, the air conditioner control unit 150 determines whether the CO2 concentration P6 is higher than the sixth correction value J6c. When the CO2 concentration P6 is higher than the sixth correction value J6c, the air conditioner control unit 150 determines that the window fogging condition is satisfied. The CO2 concentration P6 being higher than the sixth correction value J6c corresponds to the window fogging condition. The sixth correction value J6c is a determination value for determining whether the window fogging condition is satisfied and corresponds to the window fogging determination value. The air conditioner control unit 150 compares the CO2 concentration P6 with the sixth correction value J6c. The determination result of whether the CO2 concentration P6 is higher than the sixth correction value J6c corresponds to the comparison result between the window fogging parameter and the window fogging determination value. The function for performing the process of step S508 in the air conditioner control unit 150 corresponds to the parameter determination unit.

[0141] In step S510, the air conditioner control unit 150 determines whether the internal air duration P7 is longer than the seventh correction value J7c. When the occupant is in the eVTOL 10 and the internal air duration P7 is longer than the seventh correction value J7c, the air conditioner control unit 150 determines that the window fogging condition is satisfied. The occupant being in the eVTOL 10 and the internal air duration P7 being longer than the seventh correction value J7c corresponds to the window fogging condition. The seventh correction value J7c is a determination value for determining whether the window fogging condition is satisfied and corresponds to the window fogging determination value. The air conditioner control unit 150 compares the internal air duration P7 with the seventh correction value J7c. The determination result of whether the internal air duration P7 is longer than the seventh correction value J7c corresponds to the comparison result between the window fogging parameter and the window fogging determination value. The functions for performing the processes of steps S509 and S510 in the air conditioner control unit 150 correspond to the parameter determination unit.

[0142] In step S512, the air conditioner control unit 150 determines whether the inside-outside difference change speed P8 is faster than the eighth correction value J8c. When the inside-outside difference change speed P8 is higher than the eighth correction value J8c, the air conditioner control unit 150 determines that the window fogging condition is satisfied. The inside-outside difference change speed P8 being higher than the eighth correction value J8c is equivalent to the window fogging condition. The eighth correction value J8c is a determination value for determining whether the window fogging condition is satisfied, and is equivalent to the window fogging determination value. The air conditioner control unit 150 compares the inside-outside difference change speed P8 with the eighth correction value J8c. The determination result of whether the inside-outside difference change speed P8 is faster than the eighth correction value J8c is equivalent to the comparison result between the window fogging parameter and the window fogging determination value. The function of the air conditioner control unit 150 that executes the process of step S512 is equivalent to the parameter determination unit and the inside-outside determination unit.

[0143] According to the present embodiment, the air conditioner control unit 150 corrects determination reference values such as the fourth determination value J4 to obtain window fogging determination values such as the fourth correction value J4c for determining whether the window fogging condition is satisfied. In this configuration, by correcting the determination reference value according to the in-vehicle environment information or the out-of-vehicle environment information, etc., the window fogging determination value can be set to a value suitable for the in-vehicle environment or the out-of-vehicle environment. Therefore, the accuracy of the comparison result between the window fogging parameter such as the outside air temperature change speed P4 and the window fogging determination value can be improved. Therefore, the determination accuracy of whether the window fogging condition is satisfied can be further improved by the corrected window fogging determination value.

[0144] According to the present embodiment, in the correction of the reference determination value for obtaining the window fogging determination value, the pre-takeoff inside-outside difference P8b, the number of passengers, and the outside air quality information are used. Therefore, when the pre-takeoff inside-outside difference P8b affects the easiness of window fogging occurrence, the window fogging determination value becomes a value corresponding to the pre-takeoff inside-outside difference P8b, thereby enabling the improvement of the estimation accuracy of window fogging occurrence. In addition, when the number of passengers affects the easiness of window fogging occurrence, the window fogging determination value becomes a value corresponding to the number of passengers, thereby enabling the improvement of the estimation accuracy of window fogging occurrence. Therefore, the situation where window fogging is likely to occur but outside air introduction is not performed can be suppressed by the pre-takeoff inside-outside difference P8b and the number of passengers.

[0145] In addition, since the window fogging determination value becomes a value corresponding to the external air quality information, it may be difficult to introduce external air in the case of poor external air quality. For example, in the case where the airspace in which the eVTOL 10 flies is an abnormal airspace, it may be difficult to select the introduction of external air. Therefore, it is less likely to cause window fogging with the introduction of external air. On the other hand, it is possible to suppress other adverse conditions different from window fogging caused by the pollution of the external air introduced into the cabin 15. As an abnormal airspace, there are airspaces with serious air pollution such as haze.

[0146] <Third Embodiment> In the above first embodiment, external air is introduced when the window fogging condition is satisfied, and the introduction of external air is stopped when the window fogging condition is not satisfied. In contrast, in the third embodiment, external air may be introduced in either the case where the window fogging condition is satisfied or not satisfied. The structures, operations, and effects not specifically described in the third embodiment are the same as those in the first embodiment above. In the third embodiment, the description will be centered on the points different from the first embodiment above.

[0147] The operation mode of the air conditioning system 110 includes a mixed mode. The mixed mode is an operation mode in which the air conditioning system 110 performs both internal air circulation and external air introduction. The mixed mode is one of the internal air circulation functions and one of the external air introduction functions. In the mixed mode, both the internal air circulation in the cabin 15 and the air conditioning system 110 and the inhalation of the external air Air2 introduced into the cabin 15 are performed. In the mixed mode, the inhalation switching unit 127 is set to the mixed state. In the mixed mode, the air conditioning control unit 150 can adjust the amount of external air introduced. The amount of external air introduced is the amount of the inhaled external air Air2 introduced into the cabin 15.

[0148] For example, in the mixed mode, the amount of external air introduced is changed in multiple stages. The mixed mode includes a first mixed mode and a second mixed mode. The air conditioning control unit 150 can switch the operation mode to the first mixed mode and the second mixed mode. The amount of external air introduced in the second mixed mode is set to be more than the amount of external air introduced in the first mixed mode. On the other hand, the amount of external air introduced in the second mixed mode is set to be less than the amount of external air introduced in the external air mode.

[0149] Refer to Figure 8The flowchart is used to illustrate the air conditioner control process of this embodiment. Similar to the first embodiment described above, the air conditioner control unit 150 performs the processes of steps S101 to S106. When the window fogging condition does not hold in step S104, the air conditioner control unit 150 proceeds to step S601. The air conditioner control unit 150 performs an external air maintenance process in step S601. In the external air maintenance process, the amount of external air introduced into the machine room 15 can be maintained. When the current operation mode is the mixed mode, the operation mode is maintained as the mixed mode in the external air maintenance process. When the air conditioner control unit 150 proceeds to step S109 after step S601, as a notification process, it notifies, for example, that the operation mode is maintained as the mixed mode and so on.

[0150] For steps S105 and S106, even when the window fogging condition holds and the external air is abnormal, similar to the case where the window fogging condition does not hold, the air conditioner control unit 150 proceeds to step S601 and performs an external air maintenance process. When the air conditioner control unit 150 proceeds from step S106 via step S601 to step S109, as a notification process, it notifies, for example, that the window fogging condition holds, the external air is abnormal, the amount of external air introduced is maintained, and so on.

[0151] For steps S105 and S106, when the window fogging condition holds and the external air is normal, the air conditioner control unit 150 proceeds to step S602. The air conditioner control unit 150 performs an external air increase process in step S602. In the external air increase process, the amount of external air introduced into the machine room 15 increases. The air conditioner control unit 150 switches the operation mode of the air conditioner system 110 to increase the amount of external air introduced. For example, when the current operation mode is the first mixed mode, the air conditioner control unit 150 increases the amount of external air introduced by switching the operation mode from the first mixed mode to the second mixed mode. Additionally, when the current operation mode is the second mixed mode, the air conditioner control unit 150 increases the amount of external air introduced by switching the operation mode from the second mixed mode to the external air mode.

[0152] When the air conditioner control unit 150 proceeds to step S109 after step S602, as a notification process, it notifies that the operation mode is switched to increase the amount of external air introduced and so on. The function of the air conditioner control unit 150 that executes the process of step S602 is equivalent to an external air increase unit.

[0153] <Fourth Embodiment> In the above first embodiment, when the eVTOL 10 performs vertical takeoff or vertical landing, external air is introduced into the cabin 15 regardless of the flight altitude P1 or the lift-off speed P2. In contrast, in the fourth embodiment, when the eVTOL 10 performs vertical takeoff or vertical landing, external air is introduced into the cabin 15 according to the flight altitude P1 or the lift-off speed P2. Structures, operations, and effects not specifically described in the fourth embodiment are the same as those in the above first embodiment. In the fourth embodiment, the description will focus on the points different from the above first embodiment.

[0154] The air-conditioning control unit 150 performs the window fogging determination process in the same manner as in the above first embodiment. In the window fogging determination process of the present embodiment, a determination related to vertical takeoff and vertical landing is performed. In the window fogging determination process of the present embodiment, a determination related to the internal air humidity P5, etc. may also be performed in the same manner as in the above first embodiment.

[0155] Refer to Figure 9 The flowchart of is used to illustrate the window fogging determination process. In steps S701 to S706 of the window fogging determination process, the air-conditioning control unit 150 uses flight information to determine whether the window fogging condition is satisfied. The function of the air-conditioning control unit 150 that executes the processes of steps S701 to S706 is equivalent to the flight determination unit.

[0156] In step S701, the air-conditioning control unit 150 performs a vertical takeoff determination in the same manner as step S201 of the above first embodiment. When the eVTOL 10 vertically takes off, the air-conditioning control unit 150 proceeds to step S702. In step S702, the air-conditioning control unit 150 determines whether the flight altitude P1 is higher than the first determination value J1 in the same manner as step S203 of the above first embodiment. When the flight altitude P1 is higher than the first determination value J1, the air-conditioning control unit 150 proceeds to step S703. In step S703, the air-conditioning control unit 150 determines whether the lift-off speed P2 is faster than the second determination value J2 in the same manner as step S204 of the above first embodiment. In step S703, the rising speed when the eVTOL 10 vertically takes off is set as the lift-off speed P2.

[0157] When the eVTOL 10 vertically takes off, when the flight altitude P1 is higher than the first determination value J1 and the lift-off speed P2 is faster than the second determination value J2, the air-conditioning control unit 150 determines that the window fogging condition is satisfied. In addition to the eVTOL 10 vertically taking off, the flight altitude P1 being higher than the first determination value J1 and the lift-off speed P2 being faster than the second determination value J2 is equivalent to the window fogging condition. The function of the air-conditioning control unit 150 that executes the processes of steps S702 and S703 is equivalent to the parameter determination unit.

[0158] When the window fogging condition is satisfied in steps S701 to S703, the air conditioner control unit 150 proceeds to step S708. In step S708, the air conditioner control unit 150 performs the condition satisfaction process in the same manner as step S214 of the first embodiment described above.

[0159] When the window fogging condition is not satisfied in steps S701 to S703, the air conditioner control unit 150 proceeds to step S704. In step S704, the air conditioner control unit 150 performs a vertical landing determination in the same manner as step S202 of the first embodiment described above. When the eVTOL 10 makes a vertical landing, the air conditioner control unit 150 proceeds to step S705. In step S705, the air conditioner control unit 150 determines whether the flight altitude P1 is higher than the first determination value J1 in the same manner as step S203 of the first embodiment described above. When the flight altitude P1 is higher than the first determination value J1, the air conditioner control unit 150 proceeds to step S706. In step S706, the air conditioner control unit 150 determines whether the lifting speed P2 is faster than the second determination value J2 in the same manner as step S204 of the first embodiment described above. In step S706, the descending speed at the time of the vertical landing of the eVTOL 10 is set as the lifting speed P2.

[0160] When the eVTOL 10 makes a vertical landing, if the flight altitude P1 is higher than the first determination value J1 and the lifting speed P2 is faster than the second determination value J2, the air conditioner control unit 150 determines that the window fogging condition is satisfied. Except for the vertical landing of the eVTOL 10, the situation where the flight altitude P1 is higher than the first determination value J1 and the lifting speed P2 is faster than the second determination value J2 corresponds to the window fogging condition. The function of the air conditioner control unit 150 that performs the processes of steps S705 and S706 is equivalent to the parameter determination unit.

[0161] When the window fogging condition is satisfied in steps S704 to S706, the air conditioner control unit 150 proceeds to step S708 and performs the condition satisfaction process. When the window fogging condition is not satisfied in steps S701 to S706, the air conditioner control unit 150 proceeds to step S707. In step S707, the air conditioner control unit 150 performs the condition non - satisfaction process in the same manner as step S213 of the first embodiment described above.

[0162] <Other Embodiments> The disclosure of this specification is not limited to the illustrated embodiments. This disclosure includes the illustrated embodiments and modifications made by those skilled in the art based thereon. For example, the disclosure is not limited to the combination of components and elements shown in the embodiments, and various modifications can be made for implementation. The disclosure can be implemented in various combinations. The disclosure may have additional parts that can be added to the embodiments. The disclosure includes structures in which components and elements of the embodiments are omitted. The disclosure includes the replacement or combination of components and elements between one embodiment and another. The technical scope of the disclosure is not limited to the description of the embodiments. The technical scope of the disclosure should be understood to be represented by the description of the claims, and also includes all modifications within the meaning and scope equivalent to the description of the claims.

[0163] In each of the above embodiments, when the window fogging condition is satisfied, it is only necessary to introduce outside air in a manner that suppresses window fogging, and the amount of outside air introduced does not necessarily have to increase. For example, when the window fogging condition is satisfied, the position of the outside air introduced can also be changed to suppress window fogging. In a structure in which a plurality of air-conditioning outlets 137 are provided in the machine room 15, when the window fogging condition is satisfied, the air-conditioning outlet 137 that blows out the outside air Air2 sucked in as air-conditioning air Air3 can also be changed.

[0164] For example, in the machine room 15, in a structure in which air-conditioning outlets 137 are respectively provided in the passenger compartment and the pilot's compartment, when the window fogging condition is satisfied, outside air can be introduced into the pilot's compartment by blowing out the outside air Air2 sucked in from the air-conditioning outlet 137 in the pilot's compartment. In this case, the introduction of outside air for preventing fogging is preferably limited to the pilot's compartment in the passenger compartment and the pilot's compartment. Thereby, fogging of the window 16 in the pilot's compartment can be prevented without affecting the air in the passenger compartment.

[0165] In addition, in the machine room 15, in a structure in which a plurality of air-conditioning outlets 137 include a window-facing air-conditioning outlet and other air-conditioning outlets facing other directions, when the window fogging condition is satisfied, the outside air Air2 sucked in can also be blown out from the window-facing air-conditioning outlet to the window 16. The window-facing air-conditioning outlet is the air-conditioning outlet 137 that blows out the outside air Air2 sucked in toward the window 16. The other air-conditioning outlets facing other directions are the air-conditioning outlets 137 that blow out the outside air Air2 sucked in toward a direction different from the window 16.

[0166] In addition, in a structure where multiple windows 16 include a pilot window and a passenger window, external air can also be introduced in a manner that at least suppresses fogging of the pilot window when the window fogging condition is satisfied. For example, when the window fogging condition is satisfied, external air is introduced in a manner that the inhaled external air Air2 comes into contact with at least the pilot window. The driver's window is a window through which the driver visually confirms the outside of the aircraft, etc. The passenger window is a window through which passengers visually confirm the outside of the aircraft, etc. Preventing fogging of the window 16 is particularly important for the driver's window, and the priority for preventing fogging of the passenger window, which is not used for flight, etc., is relatively low.

[0167] In the eVTOL 10, a camera for projecting an image for remote operation can also be provided in the cabin 15. In this structure, when the window fogging condition is satisfied, external air can also be introduced in a manner that suppresses fogging of the window portion projected on the camera.

[0168] In each of the above embodiments, the air conditioning control unit 150 can also use at least one of flight information, in-cabin environment information, and out-of-cabin environment information when determining whether the window fogging condition is satisfied. That is, the air conditioning control unit 150 only needs to have at least one of a flight determination unit, an internal determination unit, and an external determination unit. The air conditioning control unit 150 can also introduce external air when it is determined by at least one of the flight determination unit, the internal determination unit, and the external determination unit that the window fogging condition is satisfied. For example, the air conditioning control unit 150 can also introduce external air when it is determined by all of the flight determination unit, the internal determination unit, and the external determination unit that the window fogging condition is satisfied.

[0169] In each of the above embodiments, the air conditioning control unit 150 only needs to use at least one window fogging parameter when determining whether the window fogging condition is satisfied. That is, the air conditioning control unit 150 only needs to have at least one parameter determination unit. The air conditioning control unit 150 can also introduce external air when it is determined by at least one parameter determination unit that the window fogging condition is satisfied. For example, the air conditioning control unit 150 can also introduce external air when it is determined by all of the multiple parameter determination units that the window fogging condition is satisfied.

[0170] In each of the above embodiments, the air conditioning control unit 150 only needs to use at least one of flight information, in-cabin environment information, and out-of-cabin environment information to correct the reference determination value. The air conditioning control unit 150 can also use all of the flight information, in-cabin environment information, and out-of-cabin environment information to correct the reference determination value.

[0171] In each of the above-described embodiments, a fogging sensor for detecting fogging of the window 16 may also be provided in the eVTOL 10. For example, when the fogging sensor detects fogging of the window 16, the air-conditioning control unit 150 determines that the window fogging condition is satisfied.

[0172] In each of the above-described embodiments, the number of occupants or the like may also be used as a window fogging parameter. In a configuration where the number of occupants is used as a window fogging parameter, a window fogging determination value is set for the number of occupants. For example, in the second embodiment described above, a reference determination value may be set for the number of occupants, and the reference determination value may be corrected by a correction parameter.

[0173] In each of the above-described embodiments, the flight control unit 40 may also be included in the air-conditioning system 110. That is, at least one of the air-conditioning control unit 150 and the flight control unit 40 may also be included in the air-conditioning system 110. In this configuration, the air-conditioning system 110 is controlled by at least one of the air-conditioning control unit 150 and the flight control unit 40. In this case, at least one of the air-conditioning control unit 150 and the flight control unit 40 corresponds to an air-conditioning control device. Further, in this configuration, at least one of the processors 41 and 151 corresponds to a processing unit, and at least one of the programs 43 and 153 corresponds to an air-conditioning control program.

[0174] In each of the above-described embodiments, the eVTOL 10 may not be a tilt-rotor aircraft. That is, it may not be a configuration in which one rotor 20 serves as both a lifting rotor and a cruising rotor. For example, it may be configured such that one rotor 20 functions only as one of a lifting rotor and a cruising rotor. In this configuration, in the eVTOL 10, the plurality of rotors 20 include a lifting rotor and a cruising rotor.

[0175] In each of the above-described embodiments, the vertical takeoff and landing aircraft equipped with the air-conditioning control unit 150 may be an electric vertical takeoff and landing aircraft in which at least one EPU 50 drives at least one rotor 20. For example, it may be a configuration in which a plurality of EPUs 50 drive one rotor 20, or a configuration in which one EPU 50 drives a plurality of rotors 20.

[0176] In each of the above-described embodiments, the flying object equipped with the air-conditioning control unit 150 may be an electric one and may not be a vertical takeoff and landing aircraft.
