Description

[Technical Field]

[0001] The present disclosure relates to a ventilation system. [Background technology]

[0002] Patent Document 1 discloses a neck fan that can adjust the airflow directed toward an occupant based on the skin temperature of the occupant detected by an infrared sensor. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6676757 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when refreshing an occupant by blowing air based on the occupant's biometric information, such as skin temperature, the detection accuracy of the biometric information may not be sufficient, making it impossible to control the air blowing in accordance with the occupant's self-awareness.

[0005] An object of one aspect of the present disclosure is to realize a system that effectively refreshes an occupant by controlling airflow based on a request from the occupant. [Means for solving the problem]

[0006] In order to solve the above problems, an air blowing system according to one aspect of the present disclosure includes an air blowing unit that blows air into an environment where an occupant of a moving body is present, an air blowing start designation unit that designates the air blowing start timing at which the air blowing unit should start blowing air, an air blowing stop designation unit that designates the air blowing stop timing at which the air blowing unit should stop blowing air, and a control unit that controls the air blowing by the air blowing unit from the air blowing start timing designated by the air blowing start designation unit to the air blowing stop timing designated by the air blowing stop designation unit, and the air blowing stop designation unit designates the air blowing stop timing according to information regarding the ease of recovery from motion sickness declared in advance by the occupant.

[0007] According to the above configuration, air blowing control is performed based on information regarding the ease of recovery from motion sickness declared in advance, thereby effectively refreshing a passenger who has developed motion sickness or the like.

[0008] In the air supply system according to aspect 2 of the present disclosure, the air supply stop designation unit, when the occupant declares that they will easily recover from motion sickness, designates the air supply stop timing to be a timing when a predetermined time has elapsed after a first hour has elapsed from the air supply start timing, and, when the occupant declares that they will not easily recover from motion sickness, designates the air supply stop timing to be a timing when the predetermined time has elapsed after a second time, which is longer than the first time, has elapsed from the air supply start timing.

[0009] According to the above configuration, when a passenger declares that he or she has difficulty recovering from motion sickness, air is blown for a longer period of time than when a passenger declares that he or she has difficulty recovering from motion sickness, thereby effectively refreshing the passenger as declared by the passenger.

[0010] In the ventilation system according to aspect 3 of the present disclosure, when the occupant does not declare information regarding the ease with which the motion sickness can be cured, the ventilation stop designation unit designates the ventilation stop timing to be the timing when the predetermined time has elapsed after a third time, which is longer than the first time but shorter than the second time, has elapsed from the ventilation start timing.

[0011] According to the above configuration, if there is no information about the ease of recovery from motion sickness declared in advance, i.e., if the occupant is not aware of the ease of recovery from motion sickness, the air supply is stopped after the third time, which is longer than the first time but shorter than the second time, has elapsed. Therefore, even if there is no declaration from the occupant, the occupant can be effectively refreshed.

[0012] In the air blowing system according to aspect 4 of the present disclosure, the air blowing stop designation unit designates the air blowing stop timing as the timing when the air blowing volume is reduced and air has been blown for the predetermined period of time after the first time, the second time, or the third time has elapsed from the air blowing start timing.

[0013] According to the above configuration, the airflow volume is reduced and air is blown for a predetermined period of time after the first, second, or third hour has elapsed since the start of airflow, which not only saves energy such as electricity but also reduces the annoyance felt by refreshed occupants.

[0014] In the air blowing system according to a fifth aspect of the present disclosure, the air blowing start designation unit designates the air blowing start timing after a fourth time has elapsed since the moving object started to move.

[0015] According to the above configuration, air blowing starts automatically based on the time that has passed since the moving body started moving, so that even if the occupant is so weak that it is difficult for them to perform input operations, etc., the occupant can be refreshed.

[0016] The air supply system according to aspect 6 of the present disclosure further includes a memory unit that stores information regarding the ease with which the occupant has recovered from motion sickness declared by the occupant together with authentication information for the occupant, and the air supply stop designation unit designates the timing to stop air supply for the occupant authenticated using the authentication information, in accordance with the information regarding the ease with which the occupant has recovered from motion sickness stored in the memory unit.

[0017] According to the above configuration, the occupant is personally authenticated, and the timing for stopping the air supply is specified based on information stored in the memory unit about the occupant's ease of recovery from motion sickness, so that the occupant can be refreshed more effectively according to their characteristics.

[0018] The air blowing system according to each aspect of the present disclosure may be realized by a computer, in which case the control program for the air blowing system that causes the computer to operate as each part (software element) of the air blowing system and realizes the air blowing system on the computer, and the computer-readable recording medium on which it is recorded, also fall within the scope of the present disclosure. [Effects of the Invention]

[0019] According to one aspect of the present disclosure, air blowing control is performed based on a request from an occupant, thereby effectively refreshing the occupant. [Brief explanation of the drawings]

[0020] [Figure 1] FIG. 2 is a block diagram used to explain the functional configuration of the air blowing system according to an embodiment of the present disclosure. [Figure 2] FIG. 2 is a diagram illustrating an example of a blower unit included in the blower system according to an embodiment of the present disclosure. [Figure 3] 10A and 10B are diagrams illustrating an example of operation of the air blowing system according to an embodiment of the present disclosure. [Figure 4] 4 is an example of a flowchart relating to the operation of the air blowing system according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0021] An embodiment of the present disclosure will be described in detail below with reference to FIGS. 1 to 4. FIG. 1 is a block diagram used to explain the functional configuration of an air blowing system according to an embodiment of the present disclosure. The air blowing system 1 shown in FIG. 1 is mounted on a vehicle C, which is an example of a moving body, and includes an air blowing device 10, a switch 20, an input device 30, and a vehicle communication network 40. The air blowing device 10 includes an air blowing unit 100, a control unit 101, a storage unit 102, an air blowing start designation unit 103, and an air blowing stop designation unit 104. The air blowing unit 100 blows air into the interior environment of the vehicle C where an occupant is present. An example configuration of the air blowing unit 100 will be described later with reference to FIG. 2.

[0022] The control unit 101 is, for example, an ECU (Electronic Control Unit), and controls the blower unit 100 by executing a control program stored in the storage unit 102.

[0023] The memory unit 102 includes a non-volatile memory unit that stores the control program, as well as a volatile memory unit that is used as a work area when the program is executed. The memory unit 102 stores information about the ease with which occupants of vehicle C recover from motion sickness. The information about the ease with which occupants recover from motion sickness is information that indicates whether the occupant, when experiencing motion sickness, self-perceives that they are easy to recover from or difficult to recover from. "Easy to recover from motion sickness" means that even if motion sickness develops, the occupant will recover if they remain calm within vehicle C. On the other hand, "difficult to recover from motion sickness" means that the occupant will not recover from motion sickness even if they remain calm within vehicle C. The information about the ease with which occupants of vehicle C recover from motion sickness can be registered in advance in the memory unit 102 by a declaration by the occupant using the switch 20 or the input device 30 while in vehicle C. The occupant who stores information about the ease of recovery from motion sickness in the storage unit 102 does not have to be the occupant himself / herself, and a representative who is riding in the vehicle C may register the information.

[0024] The switch 20 may be, for example, a seat switch provided on a seat of the vehicle C, an air conditioner switch provided on an instrument panel, etc. The seat switch provided on the seat of the vehicle C includes a switch for operating the reclining mechanism of the seat, etc.

[0025] The input device 30 is configured as an input device having a display unit, such as a touch panel of a navigation system mounted on the vehicle C, or a display unit and operation switches of an audio system.

[0026] The air blow start designation unit 103 is realized, for example, by the control unit 101 executing a control program stored in the storage unit 102. Note that the air blow start designation unit 103 may be realized by a control device different from the control unit 101. The air blow start designation unit 103 designates the air blow start timing T START The air blow start designation unit 103 acquires the output signal from the switch 20 via the vehicle communication network 40. For example, when the switch 20 is turned on by the occupant, the air blow start designation unit 103 designates the air blow start timing T START to the control unit 101. Based on the output signal of the air blowing start designation unit 103, the control unit 101 causes the air blowing unit 100 to start blowing air.

[0027] The air blowing stop designation unit 104 is realized, for example, by the control unit 101 executing a control program stored in the storage unit 102. Note that the air blowing stop designation unit 104 may be realized by a control device different from the control unit 101. The air blowing stop designation unit 104 designates the air blowing stop timing T STOP The air blow stop designation unit 104 receives an output signal from the switch 20 via the vehicle communication network 40. For example, when the switch 20 is turned off by the occupant, the air blow stop designation unit 104 designates the air blow stop timing T STOPThe control unit 101 outputs a signal indicating the start timing T START After a predetermined time has elapsed, the airflow is stopped at timing T STOP Specify as follows.

[0028] An example of the blower unit 100 is shown in FIG. 2. FIG. 2 shows a schematic cross-sectional view 151 of a seat S of a vehicle C and an example of a perspective view 150 of a headrest HR of the seat S. A blower 100A shown in the perspective view 150 is an example of the blower unit 100. The headrest HR has a front cushion 50 and a rear portion 51. The rear portion 51 has a cavity 52 inside. The blower 100A is attached inside the cavity 52. ​​The blower 100A draws in air inside the cavity 52 and blows the air from an air outlet 53 provided in the lower part of the front cushion 50 or the like.

[0029] Fans 100B and 100C in schematic cross-sectional view 151 are an example of blower section 100. Fan 100B is attached inside the recline portion REC of seat S. Fan 100C is attached inside the seat bottom portion BTM of seat S. Fans 100B and 100C form a seat ventilation system (SVS) and blow air toward the surrounding environment of seat S. Fan 100B has an air temperature adjustment function that adjusts the temperature of the air it blows out.

[0030] The air blowing system 1 of FIG. 1 may include one or both of the blower 100A of the perspective view 150 and the air blower 100B of the schematic cross-sectional view 151, and may also include another air blowing unit 100 such as an air conditioner.

[0031] The air blowing system 1 has a function of refreshing the occupants of the vehicle C by blowing air from the air blowing unit 100. Here, refreshing the occupants includes not only recovering occupants who have developed motion sickness, but also calming the occupants and relieving drowsiness in the driver and the like.

[0032] An example of operation of the air blowing system 1 by the control unit 101 to realize the function of refreshing the occupants of the vehicle C will be described with reference to Figures 3 and 4. Figure 3 is a diagram showing an example of air blowing control to refresh the occupants. Figure 4 is a flowchart showing an example of operation of the air blowing system 1 by the control unit 101.

[0033] As shown in FIG. 3, the control unit 101 can set the airflow rate of the blower unit 100 to at least three levels: "strong," "weak," and "OFF."

[0034] T in Figure 3 START is the air blow start timing designated by the air blow start designation unit 103. Also, T in FIG. STOP is the timing at which the air blowing is stopped, designated by the air blowing stop designation unit 104.

[0035] Before starting the operation of the air blowing system 1, the control unit 101 accepts registration of information regarding the ease with which the occupant of the vehicle C recovers from motion sickness. For example, when the occupant gets into the vehicle C, the control unit 101 accepts input of registration information regarding the ease with which the occupant recovers from motion sickness via the input device 30, and stores the registration information in the storage unit 102.

[0036] When the occupant of vehicle C declares using the input device 30 that he or she easily recovers from motion sickness, information indicating that "he or she easily recovers from motion sickness", for example, a flag "0", is stored in the memory unit 102. Also, when the occupant of vehicle C declares using the input device 30 that he or she has difficulty recovering from motion sickness, information indicating that "he or she has difficulty recovering from motion sickness", for example, a flag "1", is stored in the memory unit 102.

[0037] In S200 of FIG. 4, the control unit 101 determines the air blowing start timing T START For example, when the switch 20 is turned on, the control unit 101 receives the air blow start timing T START When a signal indicating the start of airflow is received, STARTIf the switch 20 is not turned on, the air blow start timing T START Since the control unit 101 has not received a signal indicating this (S200: NO), the control unit 101 ends the operation of Fig. 4. After the control unit 101 ends the operation of Fig. 4, it starts to repeatedly perform the operation of Fig. 4 at a predetermined execution cycle. While the control unit 101 is not performing the operation of Fig. 4, it can perform other operations using the blower unit 100.

[0038] As shown in FIG. 3, the control unit 101 determines the air blowing start timing T START When this occurs, the control unit 101 sets the airflow rate of the blower 100 to "strong" (S201 in FIG. 4). After setting the airflow rate of the blower 100 to "strong", the control unit 101 proceeds to S202 in FIG.

[0039] In S202, the control unit 101 determines whether or not the storage unit 102 contains registered information about the occupant of the vehicle C regarding how easily they can recover from motion sickness. If the storage unit 102 contains registered information about how easily they can recover from motion sickness (S202: YES), and the information indicates that the occupant is "easily cured of motion sickness" (S203: YES), the control unit 101 determines whether or not the occupant can recover from motion sickness for a time T STRONG is set to a predetermined first time T1 (S204). STRONG is the time for which air is blown at a "high" airflow rate, as shown in Fig. 3. The first time period T1 is set to a time within the range of 1 to 5 minutes, for example.

[0040] If the storage unit 102 contains registered information about the ease of recovery from motion sickness (S202: YES in FIG. 4) and the information indicates that "motion sickness is difficult to cure" (S203: NO), the control unit 101 determines whether the time T STRONG is set to a predetermined second time T2 (S205). The second time T2 is longer than the first time T1 and is set to, for example, within the range of 11 to 15 minutes.

[0041] If there is no registered information about the ease of recovery from motion sickness in the memory unit 102, for example, if the occupant does not recognize the ease of recovery from motion sickness and has not registered information about "the ease of recovery from motion sickness" (S202: NO), the control unit 101 STRONG is set to a predetermined third time T3 (S206). The third time T3 is longer than the first time T1 and shorter than the second time T2, and is set to a time within the range of, for example, 6 to 10 minutes.

[0042] In S204, S205 or S206 of FIG. STRONG When the time T is set, the control unit 101 starts blowing air by the blower 100 (S207), and the process proceeds to S208. In S208, the control unit 101 determines the time T at which the blowing started in S207. START From time T STRONG While the time has not elapsed (S208: NO), the blower 100 continues to blow air at the "strong" airflow rate, as shown in FIG.

[0043] In S207 of FIG. 4, the air blowing start timing T START From time T STRONG The setting change timing T has elapsed SHIFT If this is the case (S208: YES), the airflow rate of the blower unit 100 is set to "weak" (S209). When the airflow rate of the blower unit 100 is set to "weak," as shown in FIG. 3, the airflow rate of the blower unit 100 is gradually reduced toward the "weak" airflow rate setting. While the airflow rate is gradually reduced toward the "weak" airflow rate setting, the blower unit 100 blows air according to the setting, and after the "weak" airflow rate is reached, the blower unit 100 blows air at the "weak" airflow rate. This not only improves the success rate of refreshing the occupant, but also reduces the possibility that an occupant who has already been sufficiently refreshed will be annoyed by the strong airflow.

[0044] When the occupant of the vehicle C turns off the switch 20 (S210: YES), the air blow stop designation unit 104 determines the air blow stop timing T STOPis specified, the control unit 101 sets the airflow rate of the air blowing unit 100 to "OFF" and ends the air blowing (S212), thereby ending the operation of FIG.

[0045] Also, even if the occupant of the vehicle C has not turned off the switch 20 (S210: NO), as shown in FIG. 3, the air blowing start timing T START From time T STRONG (First time T1, second time T2, or third time T3) has passed. SHIFT (S208: YES) for a predetermined time T WEAK When the time has elapsed (S211: YES), the airflow stop designation unit 104 designates the airflow stop timing T STOP is specified, the control unit 101 sets the airflow rate of the air blowing unit 100 to "OFF" and ends the air blowing (S212), thereby ending the operation of FIG.

[0046] That is, even if the occupant of the vehicle C does not turn off the switch 20, the air blowing stop command unit 104 determines the air blowing start timing T START From a given time T STRONG +T WEAK The timing at which the airflow stops is T STOP At this time, the air blow stop timing T STOP is the time T STRONG That is, the airflow stop specifying unit 104 determines the airflow stop timing T STOP can be specified.

[0047] Predetermined time T STRONG +T WEAK is the time T1+T when the occupant of vehicle C declares that he / she is easily cured of motion sickness. WEAK Therefore, the time when the occupant of vehicle C declares that it is difficult to recover from motion sickness is T2+T WEAK is longer by T2-T1.

[0048] In addition, the predetermined time T STRONG +T WEAKis the time T3+T when the occupant of vehicle C has not registered information on how easily they recover from motion sickness in the memory unit 102, such as when they have not declared whether they are easily cured of motion sickness. WEAK is the time T1+T WEAK longer than time T2+T WEAK will be shorter than

[0049] In this way, the control unit 101 determines whether the air blowing start timing T START The air blow stop timing T designated by the air blow stop designation unit 104 STOP The blower 100 is controlled until Furthermore, by automatically stopping the air blowing from the air blowing unit 100, it is possible to save energy such as electricity.

[0050] [Action and effect] As described above, the air blowing system 1 includes the air blowing unit 100 that blows air to the inside of the vehicle C and the air blowing start timing T START and a blowing start specifying unit 103 that specifies the blowing start timing T STOP and the air blowing start timing T START The air blow stop timing T designated by the air blow stop designation unit 104 STOP The control unit 101 controls the blowing of air by the blowing unit 100 until the timing T STOP Therefore, the air blowing system 1 can effectively refresh a passenger who has developed motion sickness by controlling the air blowing based on information about the ease of recovery from motion sickness that has been declared in advance. Also, the air blowing system 1 can determine the air blowing stop timing T STOP This allows for stable operation.

[0051] [Modification] In the above embodiment, the control unit 101 determines whether the time T STRONG After the time T has elapsed (S208: YES), the airflow rate of the blower 100 is set to "weak" (S209). However, it is also possible not to blow air at the "weak" airflow rate. That is, after the time T STRONG After the time has elapsed (S208: YES), the airflow rate may be immediately set to "OFF."

[0052] In the above embodiment, when the control unit 101 sets the airflow rate of the air blower 100 to "weak" (S209), the control unit 101 gradually decreases the airflow rate of the air blower 100 toward the "weak" airflow rate setting, as shown in FIG. 3. However, at the airflow start timing T START (S207) to time T STRONG After the time has elapsed (S208: YES), the airflow rate may be immediately set to "weak."

[0053] In the above embodiment, the information regarding the ease of recovery from motion sickness is stored as a flag in the storage unit 102, but the data format of the information regarding the ease of recovery from motion sickness is not limited to this. For example, the passenger may be asked to declare a value that evaluates the ease of recovery from motion sickness on a scale of three or more levels. In this case, the time T STRONG The air blowing start timing T START From time T STRONG The amount of air blown by the blower 100 during the time period may be set to be proportional to the value declared by the occupant.

[0054] Furthermore, information on the ease with which a passenger recovers from motion sickness may be stored in the storage unit 102 together with authentication data for authenticating the passenger. For example, information on the ease with which a passenger recovers from motion sickness may be stored in the storage unit 102 together with facial information or voice information of the passenger. When information on the ease with which a passenger recovers from motion sickness is stored in the storage unit 102 together with authentication data, the air blowing system 1 is provided with a camera capable of photographing the passenger's face and a sound collection unit that collects the passenger's voice for facial or voice authentication purposes. Specifically, the control unit 101 authenticates the passenger by comparing the facial image of the passenger taken by the camera with the facial information of the passenger stored in the storage unit 102. Then, information on the ease with which the passenger recovers from motion sickness is obtained from the storage unit 102 for the authenticated passenger.

[0055] In the above embodiment, the blower device 10 includes the blower unit 100, the control unit 101, the memory unit 102, the blower start command unit 103, and the blower stop command unit 104. However, components other than the blower unit 100 may be provided outside the blower device 10. For example, the control unit 101 and the memory unit 102 may be provided in another ECU provided inside the vehicle C, or in an external server connected via a telecommunications line. Furthermore, the control unit 101 and the memory unit 102 may be configured as an integrated unit with the blower unit 100. The blower start command unit 103 and the blower stop command unit 104 may be realized by the same component, or may be included in the control unit 101.

[0056] In the above embodiment, the air blow start specifying unit 103 determines the air blow start timing T START However, the airflow start timing T START For example, the air blowing start specifying unit 103 may specify the time T4 after the vehicle C starts traveling as the air blowing start timing T STARTThe fourth time T4 may be, for example, 30 minutes. Information regarding the timing at which vehicle C starts traveling may be acquired from a vehicle control device that receives signals from a wheel speed sensor or the like, or from a navigation system that detects the position of vehicle C based on a GPS signal or the like.

[0057] The fourth time T4 may be changed based on information about the ease of recovery from motion sickness declared by the occupant, information about the sway, speed, acceleration, etc. of the vehicle C acquired from the control system of the vehicle C, information about the road on which the vehicle C is traveling, etc. For example, if information indicating that the occupant of the vehicle C has difficulty recovering from motion sickness is stored, the air blow start timing T START In addition, when the average of the swaying or speed change of the vehicle C exceeds a predetermined threshold, or when the vehicle C is traveling on an unpaved road, the air blowing start timing T START It may be possible to speed up the process.

[0058] Cool air may be blown by adding a cooling function to the blower 100. This cooling function is, for example, a Peltier device.

[0059] In the above-described embodiment and each modified example, the ventilation system 1 is mounted on a vehicle C, but this is not limiting. For example, the ventilation system 1 may be provided on a moving body other than a vehicle C, such as a train, a ship, or an airplane.

[0060] [Software implementation example] The functions of the air blowing system (hereinafter referred to as the "system") can be realized by a program that causes a computer to function as the system, and a program that causes a computer to function as each control block of the system (particularly the control unit 101, the air blowing start designation unit 103, and the air blowing stop designation unit 104).

[0061] In this case, the system includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing the functions described in each of the above embodiments.

[0062] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0063] In addition, some or all of the functions of each of the control blocks can be realized by logic circuits. For example, integrated circuits in which logic circuits that function as each of the control blocks are formed are also included in the scope of the present disclosure. In addition, the functions of each of the control blocks can also be realized by, for example, a quantum computer.

[0064] The present disclosure is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present disclosure. [Explanation of symbols]
