Examples include a breathing support operation lamp to be presented, or a liquid crystal display that displays presentation information on a screen.

  The respiratory state detection device 600 detects the respiratory state of the occupant. As such a breathing state detection device 600, for example, a photoelectric displacement sensor that detects the breathing of the occupant by detecting the swing of the buckle portion of the seat belt due to the breathing of the occupant, or the nose / mouth portion of the occupant An infrared camera that detects the occupant's breathing by detecting a change in the temperature of the vehicle can be used.

  The control device 700 is a ROM (Read Only Memory) in which a program for supporting breathing of an occupant is stored, a CPU (Central Processing Unit) that executes the program stored in the ROM, and an accessible storage device And a functioning RAM (Random Access Memory). As an operation circuit, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like can be used instead of a CPU (Central Processing Unit).

Below, each function with which the control apparatus 700 is provided is demonstrated.

  The vehicle information acquisition function of the control device 700 acquires vehicle information indicating the traveling state of the host vehicle. Specifically, the vehicle information acquisition function acquires vehicle speed information of the host vehicle, triaxial acceleration information, steering angle information, and information on the accelerator opening and the brake pedal depression amount from the vehicle controller 300.

  The breathing information acquisition function of the control device 700 acquires information related to the breathing of the occupant detected by the breathing state detection device 600 as breathing information. Specifically, the breathing information acquisition function includes the time when the occupant exhales with one breath (expiration time), the time when the occupant breathes with one breath (inspiration time), the occupant The information including the air ventilation volume, the expiration timing, and the inspiration timing in one breath is acquired as the respiratory information. For example, in the present embodiment, as shown in FIG. 3 (A), the breathing information acquisition function stores breathing information including an expiration time, an inspiration time, an air ventilation amount, an expiration timing, and an inspiration timing. It can be acquired as a graph showing the respiratory state. FIG. 3A is a graph showing the current breathing state of the occupant. In addition, the breathing information acquisition function integrates the information on the breathing state since the occupant got on and performs statistical processing such as averaging, so that expiration time, inspiration time, air ventilation volume, expiration timing, inspiration It is good also as a structure which calculates the respiratory information containing a timing.

  The breathing support mode acquisition function of the control device 700 acquires information on the breathing support mode selected by the occupant via the input device 400. For example, the breathing support mode acquisition function is selected by the occupant through the input device 400 among the breathing support modes including the metabolic improvement mode, the blood pressure reduction mode, the relaxation mode, the fatigue reduction mode, the stress reduction mode, and the arousal level improvement mode. The information of the performed breathing support mode is acquired from the input device 400.

  The traveling state determination function determines the traveling state of the host vehicle based on the vehicle information of the host vehicle acquired by the vehicle information acquisition function. For example, the traveling state determination function can determine whether or not the host vehicle is traveling based on the vehicle speed information of the host vehicle in the vehicle information.

  The target value setting function of the control device 700 sets a target value obtained by quantifying the respiratory state targeted by the occupant based on the information on the respiratory support mode acquired by the respiratory support mode acquisition function. For example, in the present embodiment, a table indicating the relationship between the breathing support mode and each target value is stored in the RAM of the control device 700, and the target value setting function refers to this table and the occupant sets a target. The target values for the expiration time, the inspiration time, and the air ventilation amount are set as the target expiration time, the target inspiration time, and the target air ventilation amount, respectively.

  The divergence degree calculation function of the control device 700 is based on the occupant's current breathing state acquired by the breathing information acquisition function and the breathing support mode selected by the occupant calculated by the target value calculation function. The degree of deviation from the breathing state to be calculated is calculated as the degree of deviation.

  Specifically, in the present embodiment, the divergence calculation function is based on the occupant's current exhalation time, inspiration time, air ventilation amount included in the respiration information, and the occupant set by the target value setting function. The degree of divergence from the expiration time, the inspiration time, and the air ventilation volume is calculated.

  For example, when the occupant's current expiration time is 2 seconds and the target expiration time is 6 seconds, the divergence degree calculation function calculates the divergence degree of the expiration time as three times. Also, the divergence degree calculation function calculates the divergence degree of the inspiration time as double when the current inspiration time of the occupant is 2 seconds and the target inspiration time is 4 seconds. Furthermore, the deviation degree calculation function can calculate the degree of deviation of the air ventilation amount by comparing the current air ventilation amount of the occupant with the target air ventilation amount.

  The intermediate value calculation function of the control device 700 is a transient during the transition from the current breathing state of the occupant to the target breathing state when the divergence degree calculated by the divergence degree calculation function is equal to or greater than a predetermined value. An intermediate value obtained by quantifying the respiratory state in the state is calculated. Specifically, the intermediate value calculation function determines whether the exhalation time divergence degree, the inspiration time divergence degree, and the air ventilation amount divergence degree calculated by the divergence degree calculation function are each equal to or greater than a predetermined value. Based on the determination result, the occupant's current exhalation time, inspiration time, and air ventilation volume acquired by the breathing information acquisition function and the occupant set by the target value setting function An intermediate value is calculated for each expiration time, inspiration time, and air ventilation amount using the expiration time, the inspiration time, and the air ventilation amount.

  Here, FIG. 3 is a diagram for explaining the relationship between the current value indicating the current breathing state of the occupant, the target value indicating the breathing state targeted by the occupant, and the intermediate value. ) Shows a current value obtained by quantifying the current breathing state of the occupant, and FIG. 3C shows a target value obtained by quantifying the breathing state targeted by the occupant. FIG. 3B shows an intermediate value obtained by quantifying the respiratory state in a transient state between the current respiratory state of the occupant and the respiratory state targeted by the occupant. As shown in FIG. 3A, the occupant's current breathing is shallow and fast, and as shown in FIG. 3C, the occupant's target breathing is deep and slow breathing. Thus, when it is determined that the current breathing state of the occupant and the breathing state targeted by the occupant are greatly deviated and the divergence calculated by the divergence calculation function is greater than or equal to a predetermined value, As shown in FIG. 3B, the intermediate value calculation function calculates an intermediate value obtained by quantifying the respiratory state in the transitional state for shifting from the current respiratory state of the occupant to the target respiratory state of the occupant. .

  For example, when the occupant's current expiration time is 2 seconds and the occupant's target expiration time is 4 seconds, the intermediate value calculation function calculates the intermediate value of the expiration time as 3 seconds. be able to. The intermediate value calculation function calculates the intermediate value of the inspiration time as 2 seconds when the current inspiration time of the occupant is 1 second and the inspiration time targeted by the occupant is 3 seconds. be able to.

  The intermediate value is not limited to one, and the intermediate value calculation function can calculate a plurality of intermediate values. In particular, in the present embodiment, the intermediate value calculation function calculates one or two or more intermediate values so that the divergence between the current value indicating the current breathing state of the occupant and the intermediate value does not exceed twice. For example, if the occupant's current exhalation time is 2 seconds and the occupant's target exhalation time is 10 seconds, if the intermediate value is calculated as 6 seconds, the occupant's current exhalation time is Since the intermediate value is 6 seconds with respect to 2 seconds, the divergence is tripled. In such a case, the intermediate value calculation function calculates an intermediate value of 2 or more so that the degree of divergence between the current value and the intermediate value is twice or less. For example, in the above example, the intermediate value calculation function calculates the expiration time of 4 seconds, 6 seconds, and 8 seconds as the intermediate value. The exhalation time in the above example is an example and is not particularly limited. For example, in the above example, the first intermediate value may be set to 3.5 to 3.9 seconds.

  Similarly, the intermediate value calculation function can calculate one or two or more intermediate values for the inspiration time and the air hyperventilation amount.

  The control function of the control device 700 controls the operation of the seat back movable device 100 and the seat lumbar movable device 200 based on the target value set by the target value setting function or the intermediate value calculated by the intermediate value calculation function. To do.

  For example, the control function operates the seat lumbar movable device 200 so that the protruding amount of the actuator 210 becomes small as shown in FIG. The seat back movable device 100 is operated so that 2 occurs forward (approximately in the negative direction of the X-axis direction). Accordingly, the occupant's posture can be changed so that the occupant's lungs are pushed upward by the abdominal cavity at the timing when the occupant exhales. As a result, it becomes easier for the occupant to exhale, and the exhalation by the occupant can be supported. Further, the control function adjusts the operation speed of the seat lumbar movable device 200 and the seat back movable device 100 and operates the seat back movable device 100 and the seat lumbar movable device 200 by taking the expiration time targeted by the occupant. Thus, it is possible to support the occupant's exhalation so that the occupant can easily exhale at the expiration time targeted by the occupant.

  In addition, as shown in FIG. 2B, the control function increases the protruding amount of the actuator 210 in accordance with the timing when the occupant inhales, and the actuator 210 is in the occupant direction (a negative direction in the substantially X-axis direction). The seat lumbar movable device 200 is operated so as to protrude to the rear, and the seat back movable device 100 is operated so that the seat back 2 tilts backward (substantially in the positive direction of the X-axis direction). Thereby, in accordance with the timing when the occupant inhales, the pressure on the lungs by the abdominal cavity is eliminated, and the occupant's posture can be changed so that the occupant's lungs expand about 10 cm downward. As a result, the occupant can easily inhale and can support the inhalation by the occupant. In addition, the control function adjusts the operation speed of the seat lumbar movable device 200 and the seat back movable device 100 and operates the seat back movable device 100 and the seat lumbar movable device 200 by multiplying the inspiration time targeted by the occupant. Thus, it is possible to assist the occupant to inhale so that the occupant can easily inhale during the inhalation time targeted by the occupant.

  As shown in FIG. 2A, the control function operates the seat lumbar movable device 200 so that the protruding amount of the actuator 210 is small, and the seat back 2 moves forward (in the negative direction of the substantially X-axis direction). 2), the exhalation support operation for operating the seat back movable device 100, and as shown in FIG. 2B, the protruding amount of the actuator 210 is increased so that the actuator 210 moves in the occupant direction (substantially in the X-axis direction). The seat lumbar movable device 200 is operated so as to protrude in the negative direction), and the inspiration support operation is performed so that the seat back movable device 100 is operated so that the seat back 2 tilts backward (approximately the positive direction in the X-axis direction). And are repeated alternately. Here, it is known that the occupant's breathing can be guided to abdominal breathing by alternately moving the occupant's diaphragm vertically, and in this embodiment, the occupant's diaphragm is moved by the exhalation support operation. Since the occupant's diaphragm can be moved upward (positive direction in the Y-axis direction) by moving downward (the negative direction in the Y-axis direction) and the inspiration support operation, the breathing of the occupant can be changed to abdominal breathing. Can help.

  Further, in the present embodiment, the control function supports the seat back movable device 100 and the seat lumbar during the inspiration time as shown in FIG. The operation amount of the movable device 200 is controlled. Specifically, the control function first sets a value close to the current value indicating the occupant's current breathing state among the target value and the intermediate value as the target value or intermediate value that the occupant initially targets, A value that is second closest to the current value indicating the current breathing state of the occupant is set as a target value or an intermediate value that is the second target for the occupant. Similarly, the control function sequentially sets a target value or an intermediate value targeted by the occupant based on the target value and the size of the intermediate value.

  Then, the control function controls the operation amounts of the seat back movable device 100 and the seat lumbar movable device 200 during the inspiration time according to the set target value or intermediate value, as shown in FIG. Specifically, the control function increases the protrusion amount of the actuator 210 and increases the inclination angle of the seat back 2 as the set target value or intermediate value increases. For example, in this embodiment, when the control function supports the breathing of the occupant, the actuator 210 protrudes from the surface of the seat back 2 within a range of 30 to 80 mm, and the inclination angle of the seat back 2 is set to exhale. The seat back 2 is tilted within a range of 2 to 10 degrees from the tilt of the seat back 2 during the support operation. In addition, the inclination angle of the seat back 2 during the exhalation support operation is not particularly limited, but may be within a range of 90 to 110 degrees, for example.

  In the present embodiment, when the intermediate value is calculated, the control function determines the operation amounts of the seat back movable device 100 and the seat lumbar movable device 200 according to the intermediate value initially targeted by the occupant. After that, the operation amount of the seat back movable device 100 and the seat lumbar movable device 200 is increased in accordance with the target value or the intermediate value that is the second target for the occupant. As described above, in the present embodiment, when the intermediate value is calculated, the control function gradually increases the operation amounts of the seat back movable device 100 and the seat lumbar movable device 200 to thereby increase the seat back movable device 100. In addition, the sense of discomfort felt by the occupant can be reduced by the operation of the seat lumbar movable device 200. In particular, in the present embodiment, the seat back movable device 100 and the seat lumbar movable device 200 are multiplied by 15 to 60 seconds to obtain an operation amount corresponding to the target value. The uncomfortable feeling felt by the occupant can be further reduced by the operation 200.

  Next, the breathing assistance process according to the first embodiment will be described. FIG. 4 is a flowchart showing a breathing support process according to the first embodiment.

  First, in step S101, the control function of the control device 700 determines whether to support occupant breathing. For example, if an occupant is inquired about whether or not to support breathing via the information providing device 500 such as a display, and the occupant instructs the start of the breathing support, the breathing support of the occupant is performed. Judgment can be made. If it is determined in step S101 that the occupant's breathing support is to be performed, the process proceeds to step S102, and if it is determined that the occupant's breathing support is not to be performed, the process proceeds to step S112.

  In step S102, a breathing support start process is performed by the control function of the control device 700. For example, the control function notifies the start of breathing support through the information providing device 500, such as turning on a breathing support operation lamp or displaying characters or icons such as “in breathing support operation” on the display screen. To do.

  In step S103, the vehicle information acquisition function of the control device 700 acquires vehicle speed information, triaxial acceleration information, steering angle information, and vehicle information including the accelerator opening and the brake pedal depression amount.

  In step S104, the respiratory information acquisition function of the control device 700 acquires respiratory information indicating the breathing state of the occupant. Specifically, as shown in FIG. 3A, the breathing information detection function performs the breathing time, breathing time, air ventilation amount, breathing timing, and breathing time detected by the breathing state detection device 600. Respiratory information including breath timing is acquired from the respiratory condition detection device 600.

  In step S105, the information on the respiratory support mode selected by the occupant is acquired via the input device 400 by the respiratory support mode acquisition function. For example, in the present embodiment, the breathing support mode acquisition function is selected by the occupant from the breathing support modes including the metabolism improvement mode, the blood pressure reduction mode, the relaxation mode, the fatigue reduction mode, the stress reduction mode, and the arousal level improvement mode. Acquire information on the breathing support mode.

  In step S106, the target value setting function of the control device 700 sets the target values for the expiration time, the inspiration time, and the air ventilation amount based on the information on the respiratory support mode acquired in step S105. .

  For example, when the metabolic enhancement mode is selected as the breathing support mode, the target value setting function can set the expiration time as 4 seconds, the inspiration time as 10 seconds, and the air ventilation amount as 1500 ml. Further, the target value setting function may set the expiration time as 3 seconds, the inspiration time as 7 seconds, and the air ventilation amount as 1350 ml, for example, when the blood pressure reduction mode is selected as the breathing support mode. it can. Further, the target value setting function can set the expiration time as 3 seconds, the inspiration time as 5 seconds, and the air ventilation amount as 1200 ml, for example, when the relaxation mode is selected as the breathing support mode. . Similarly, the target value setting function can set target values in other respiratory support modes. For example, when the fatigue reduction mode is selected, the expiration time can be set to 5 seconds and the inspiration time can be set to 10 seconds. When the stress reduction mode is selected, the expiration time is set to The inspiration time can be set as 3 seconds and 10 seconds. The exhalation time, the inspiration time, and the air ventilation amount described above are examples, and are not particularly limited.

  In step S107, whether or not the host vehicle is traveling is determined based on the vehicle information of the host vehicle acquired in step S103 by the traveling state determination function of the control device 700. If it is determined that the host vehicle is traveling, the process proceeds to step S108. If it is determined that the host vehicle is not traveling, the process proceeds to step S111.

  In step S108, the divergence degree between the current breathing state of the occupant and the breathing state targeted by the occupant is calculated by the divergence degree calculating function of the control device 700. For example, when the occupant's current expiration time is 2 seconds and the target expiration time is 6 seconds, the divergence degree calculation function calculates the divergence degree of the expiration time as three times.

  In step S109, the intermediate value calculation function of the control device 700 determines whether or not the divergence degree calculated in step S108 is a predetermined value or more. Although the predetermined value is not particularly limited, in the present embodiment, the intermediate value calculation function can determine whether the predetermined value is 2 and the deviation degree is 2 or more. When it is determined that the degree of divergence is greater than or equal to the predetermined value, the process proceeds to step S110. On the other hand, when it is determined that the degree of divergence is less than the predetermined value, the process of step S110 is not performed and step S111 is performed. Proceed to

  In step S110, since it is determined that the degree of divergence is greater than or equal to a predetermined value, the intermediate value calculation function causes the breathing state in a transient state during the transition from the current breathing state of the occupant to the target breathing state of the occupant. Is calculated as an intermediate value.

  In step S111, the seatback movable device 100 and the seat lumbar movable device 200 are operated based on the target value calculated in step S106 or the intermediate value calculated in step S110. Specifically, when the intermediate value is not calculated, the control function is based on the expiration time, the inspiration time, and the air ventilation amount targeted by the occupant set in step S106. And the seat lumbar movable device 200 is operated. When the intermediate value is calculated, the control function allows the seat back movable device 100 and the seat lumbar movable based on the expiration time, the inspiration time, and the air ventilation amount corresponding to the intermediate value calculated in step S110. The apparatus 200 is operated.

  Further, in step S111, the control function performs the protrusion of the actuator 210 of the seat lumbar movable device 200 as shown in FIG. 2A during the expiration time in accordance with the expiration timing of the occupant acquired as the breathing information. The seat back movable device 100 is operated so that the amount is zero and, at the same time, the seat back 2 occurs forward (negative direction in the X-axis direction). As a result, the occupant's lungs are pushed by the abdominal cavity during the exhalation time, making it easier for the occupant to exhale, so that the occupant's exhalation can be supported.

  Then, when the expiration time has elapsed, the control function next causes the occupant to actuate the actuator 210 as shown in FIG. 2B during the inspiration time in accordance with the inspiration timing of the occupant acquired as respiration information. The seat lumbar movable device 200 is operated so as to project in the direction (approximately the negative direction of the X axis direction) and push the vicinity of the boundary between the thoracic vertebra and the lumbar vertebra of the occupant. The seat back movable device 100 is operated so as to fall in the positive direction. As a result, the lungs of the occupant spread downward and the occupant can easily inhale during the inspiration time, so that the occupant can inhale.

  Further, when the inspiration time has elapsed, the control function operates the seat back movable device 100 and the seat lumbar movable device 200 to support the breathing of the occupant as shown in FIG. After the elapse of time, as shown in FIG. 2B, the seat back movable device 100 and the seat lumbar movable device 200 are operated to assist the occupant inhaling. As described above, the control function repeats the operation shown in FIG. 2A and the operation shown in FIG. 2B in accordance with the expiration time and the inhalation time, whereby the breathing of the occupant is performed by abdominal breathing. Can help.

  In addition, as shown in FIG. 2B, the control function, when operating the seat lumbar movable device 200 and the seat back movable device 100, is based on the air ventilation amount set according to the breathing support mode. The operation amount of the seat back movable device 100 (inclination angle of the seat back 2) and the operation amount of the seat lumbar movable device 200 (projection amount of the actuator 210) are calculated.

  For example, in the control function, when the metabolism improvement mode is selected as the breathing support mode and the target value of the air ventilation amount is set as 1500 ml, the inclination angle of the seat back 2 is 10 degrees and the protrusion of the actuator 210 is performed. The seat back movable device 100 and the seat lumbar movable device 200 are operated so that the amount is 80 mm. Further, for example, when the blood pressure reduction mode is selected as the breathing support mode and the air ventilation amount is set as the target value, the control function has an inclination angle of the seat back 2 of 8 degrees and the actuator 210. The seat back movable device 100 and the seat lumbar movable device 200 are operated so that the protrusion amount of the air is 50 mm, the relax mode is selected as the breathing support mode, and the air ventilation amount is set as the target value of 1200 ml. In this case, the seat back movable device 100 and the seat lumbar movable device 200 are operated so that the inclination angle of the seat back 2 is 6 degrees and the protruding amount of the actuator 210 is 30 mm.

  Further, if it is determined in step S101 not to support the breathing of the occupant, the process proceeds to step S112. In step S112, a breathing support end process is performed by the control function of the control device 700. For example, the control function returns the seat back movable device 100 and the seat lumbar movable device 200 to the initial state, and for example, turns off the breathing support operation lamp and presents the operation end sound or sound, thereby causing the information providing device 500 to The end of breathing support is notified through The control function is such that when the seat back movable device 100 and the seat lumbar movable device 200 are operated to return the seat back 2 and the actuator 210 to the initial state, the uncomfortable feeling given to the occupant is reduced. The operation speed of the movable device 100 and the seat lumbar movable device 200 is suppressed (the same applies to steps S206, S209, and S219 described later).

  As described above, in the first embodiment, by operating the seat back movable device 100 and the seat lumbar movable device 200 so that the effect of the breathing support mode selected by the occupant can be obtained, the occupant's breathing is abdominal breathing. Provide support so that Specifically, during the expiration time targeted by the occupant, as shown in FIG. 2A, the seat lumbar movable device 200 is operated so that the protruding amount of the actuator 210 is reduced, and the seat back is movable. As shown in FIG. 2B, during the exhalation support operation for causing the seat back 2 to move forward (substantially in the negative direction in the X-axis direction) and the inhalation time targeted by the occupant. The seat lumbar movable device 200 is operated so that the protruding amount of the actuator 210 is increased, and the seat back movable device 100 is operated so that the seat back 2 is tilted backward (approximately the positive direction of the X-axis direction). Repeat the breath support operation. Thus, as shown in FIG. 2 (A), when performing an exhalation support operation, the occupant's lungs are pushed upward (positive direction in the Y-axis direction) by the occupant's abdominal cavity, and FIG. ) When performing an inspiration support operation, as the occupant's lungs expand downward (negative direction in the Y-axis direction), the occupant's diaphragm moves up and down, and the occupant takes abdominal breathing. Can be done. And, in this way, by making the occupant perform abdominal breathing, it is possible to stimulate the parasympathetic nerve, thereby relaxing the occupant, reducing the occupant's stress, reducing the blood pressure, The effect of improving the wakefulness and metabolism of the passenger can be obtained.

  In the present embodiment, the expiration time and the inspiration time (the operation time of the seat back movable device 100 and the operation time of the seat lumbar movable device 200), and the air ventilation are selected according to the breathing support mode selected by the occupant. By setting the amount (the movement amount of the seat back movable device 100 and the movement amount of the seat lumbar movable device 200), it is possible to effectively obtain the effect of breathing support desired by the occupant, such as relaxation and stress reduction. . In particular, in the present embodiment, the seat lumbar movable device 200 is installed in a portion of the seat back 2 that corresponds to the vicinity of the boundary between the thoracic vertebra and the spine of the occupant (near the diaphragm). Compared with the case where 200 is installed in the portion corresponding to the lumbar region of the occupant, the occupant's diaphragm can be moved greatly up and down, and the occupant can more effectively support the abdominal breathing. Further, in the present embodiment, the actuator 210 is protruded from the surface of the seat back 2 in a range of 30 to 80 mm, and the inclination angle of the seat back 2 is inclined in a range of 3 to 10 degrees from a normal angle. The occupant can appropriately perform abdominal breathing without imposing a heavy burden on the occupant's body.

  Further, in the first embodiment, the passenger's breathing is not guided only by voice, but by operating the seat back movable device 100 and the seat lumbar movable device 200 to directly change the posture of the passenger, It is possible to effectively support the breathing of the person to become abdominal breathing. In the first embodiment, as shown in FIG. 3A, the occupant detects the expiration timing and the inspiration timing based on the respiratory information indicating the occupant's current breathing state, and the occupant's expiration timing is detected. By performing the exhalation support operation in accordance with the inspiration timing and performing the inspiration support operation in accordance with the inspiration timing, it is possible to reduce a sense of incongruity felt by the occupant when assisting the occupant's breathing. Further, by performing the breathing support in accordance with the breathing timing of the occupant, it is possible to adjust the breathing timing that varies among the individual occupants and to efficiently support the breathing of the occupant.

  Further, in the first embodiment, when the occupant's current breathing state is detected and the degree of deviation between the occupant's current breathing state and the breathing state targeted by the occupant is greater than or equal to a predetermined value, an intermediate value is generated. The seat back movable device 100 and the seat lumbar movable device 200 are operated based on the intermediate value. Thus, in this embodiment, when the occupant's current breathing state and the occupant's target breathing state are greatly deviated, the occupant's current breathing state becomes the occupant's target breathing state. In addition, instead of operating the seat back movable device 100 and the seat lumbar movable device 200 at a time, based on the intermediate value, the current breathing state of the occupant gradually becomes the breathing state targeted by the occupant. Then, the seat back movable device 100 and the seat lumbar movable device 200 are operated. In particular, in this embodiment, the time ratio Weber ratio in a general human being is about 50%, so that the current breathing time of the occupant and the breathing time targeted by the occupant do not deviate by more than 2 times. By providing an intermediate value of 2 or more, it is possible to reduce a sense of discomfort given to the occupant when the occupant's current breathing state is changed to the occupant's target breathing state. Furthermore, in the present embodiment, by generating an intermediate value when the vehicle is traveling, the driver prevents the driver from paying attention to the breathing support during the breathing support while the vehicle is traveling. It is possible to drive safely.

<< Second Embodiment >>
Subsequently, a second embodiment of the present invention will be described. The breathing assistance device 1a according to the second embodiment has the same configuration as that of the first embodiment, except that it differs from the breathing assistance device 1 according to the first embodiment in the points described below. Works as well.

  FIG. 5 is a configuration diagram illustrating a respiratory assistance device 1a according to the second embodiment. In addition to the configuration of the respiratory assistance device 1 according to the first embodiment, the respiratory assistance device 1a according to the second embodiment includes an interior air quality detection device 800 and an exterior air quality detection device 900.

  The vehicle interior air quality detection device 800 detects the air quality in the passenger compartment of the host vehicle. For example, the vehicle interior air detection device 800 includes a carbon dioxide sensor, an exhaust gas sensor, a dust sensor, a temperature sensor, a humidity sensor, an odor sensor, an oxygen concentration sensor, and the like, such as carbon dioxide gas, carbon dioxide, exhaust gas (NOX), Dust, oxygen concentration, etc. can be detected. Furthermore, it is good also as a structure which monitors the amount of blood nitrogen etc. which have a bad influence on a human body by providing an atmospheric pressure sensor.

  The vehicle outside air detection device 900 detects the air quality outside the host vehicle. The vehicle outside air detection device 900 is constituted by, for example, a carbon gas sensor, an exhaust gas sensor, a dust sensor, an oxygen concentration sensor, or the like, as in the vehicle air quality detection device 800. Carbon dioxide, carbon dioxide, exhaust gas (NOX, PM2.5), dust, oxygen concentration, etc. can be detected. A sensor that is mounted on the auto conditioner and automatically switches between introduction of outside air and circulation of inside air by the auto air conditioner can also be used as the vehicle outside air detection device 900.

  In addition to the function of the control device 700 according to the first embodiment, the control device 700 according to the second embodiment includes an air quality acquisition function that acquires information on the air quality inside the vehicle interior and the air quality outside the vehicle, A window opening / closing state acquisition function for acquiring information indicating an opening / closing state of a vehicle window.

  The air quality acquisition function of the control device 700 acquires the air quality in the vehicle interior detected by the vehicle interior air quality detection device 800 from the vehicle interior air quality detection device 800 and the outside air quality detected by the vehicle exterior air quality detection device 900. The air quality is acquired from the outside air detection device 900.

  The window open / close state acquisition function of the control device 700 acquires the open / close state of windows such as windows and sunroofs. For example, in the second embodiment, the vehicle controller 300 controls the open / close state of windows, sunroofs, etc., and the window open / close state acquisition function uses a signal indicating the open / close state of windows such as windows, sunroofs, etc. 300 can be obtained.

  In addition, the control function of the control device 700 according to the second embodiment includes information indicating the air quality inside the vehicle interior and the air quality outside the vehicle acquired by the air quality acquisition function, and the window acquired by the window open / close state acquisition function. The occupant's breathing support is controlled based on the open / closed state. Specifically, the control function specifies whether the air breathing by the occupant is air outside the vehicle compartment or air outside the vehicle based on the open / closed state of the window. Furthermore, the control function determines whether the air determined to be breathing by the occupant is air suitable for breathing support based on the air quality of the specified air, and the air suitable for breathing support. If not, stop or suppress breathing support.

  Next, the breathing assistance process according to the second embodiment will be described. FIG. 6 is a flowchart showing a breathing support process according to the second embodiment.

  In steps S201 and 202, as in steps S101 and S102 of the first embodiment, it is determined whether or not to support the breathing of the occupant (step S201). Respiration support start processing is performed (step S202).

  In step S203, the air quality acquisition function of the control device 700 detects the air quality inside the vehicle interior detected by the vehicle interior air quality detection device 800 and the outside air quality detected by the vehicle exterior air quality detection device 900. Information about air quality is acquired. In step S203, the window opening / closing state acquisition function of the control device 700 acquires information about the opening / closing state of windows such as windows and sunroofs.

  In step S204, the control function of the control device 700 relates to the air quality information in the passenger compartment of the host vehicle and the air quality outside the host vehicle acquired in step S203, and the open / closed state of windows such as windows and sunroofs. Based on the information, it is determined whether the air that the occupant is breathing is the air in the passenger compartment or the air outside the vehicle.

  Specifically, the control function first determines the opening degree of the window based on information on the open / closed state of the window. For example, when the control function determines that the window is in a completely closed state, it determines that the air that the occupant is breathing is the air in the passenger compartment of the host vehicle. For example, when it is determined that the window is fully open, the control function determines that the air that the occupant is breathing is outside the vehicle. Furthermore, for example, when the control function determines that the window is in a half-open state, the occupant breathes the air with the lower air quality by comparing the air quality inside the vehicle interior with the air quality outside the vehicle. Judge that the air is. Similarly, the control function determines whether the air that the occupant is breathing is the air inside the vehicle compartment or the air outside the vehicle according to the opening of the window.

  In step S205, the control function determines whether the air quality of the air determined to be breathing in step S204 is suitable for assisting the breathing of the passenger. For example, if the concentration of the exhaust gas detected by the exhaust gas sensor exceeds a predetermined value, the control function may have an adverse effect on the human body, so such air is not suitable for deep breathing of the occupant. It can be judged. In addition, the determination of whether or not it is suitable for assisting occupant breathing includes a case where it can be determined that the smell is unpleasant and a case where it can be determined that there is an effect on the human body such as stiff shoulders and sleepiness. If it is determined that the air quality of the air that the occupant is breathing is suitable for the occupant's breathing, the process proceeds to step S208, while the air quality of the air that the occupant is breathing is suitable for the occupant's breathing. If it is determined that there is not, the process proceeds to step S206.

  In step S206, since it is determined that the air quality of the air that the occupant is breathing is not suitable for the occupant's breathing, a breathing support interruption process is performed by the control function. For example, the control function operates the seat back movable device 100 so that the inclination angle of the seat back 2 becomes the angle before the breathing support, and the seat lumbar movable device 200 so that the protrusion amount of the actuator 210 becomes zero. After that, the operations of the seat back movable device 100 and the actuator 210 are stopped. Further, the breathing support operation lamp is turned off, and a sound or voice for notifying the interruption of the breathing support is presented from the speaker, thereby informing the interruption of the breathing support through the information providing apparatus 500. In addition, FIG. 7 is a figure for demonstrating the respiration state in case the air quality is deteriorating.

  Then, after the suspension process of breathing support is performed in step 206, the process proceeds to step S207, and it is determined whether or not the breathing support is terminated by the control function. For example, the control function determines that the breathing support is to be terminated when the passenger is instructed to terminate the breathing support through the input device 400. If it is determined that the breathing support is to be ended, the process proceeds to step S219. On the other hand, if it is determined that the breathing support is not to be ended, the process returns to step S203, and again the information on the air quality inside the vehicle and the window open / closed state Is obtained, and it is determined whether the air quality is suitable for breathing.

  On the other hand, if it is determined in step S205 that the air quality of the air that the occupant is breathing is suitable for breathing, the process proceeds to step S208. In step S208, the control function determines whether the air quality of the air that the occupant is breathing is suitable for deep breathing. For example, if the carbon dioxide concentration of the air that the occupant breathes exceeds 2000 ppm, the control function may have an effect on the occupant's consciousness. It can be determined that it is not suitable. Further, when the oxygen concentration in the air is less than the predetermined value, it can be determined that the air is not suitable for deep breathing. If it is determined that the air quality of the air that the occupant is breathing is suitable for deep breathing, the process proceeds to step S210, while the air quality of the air that the occupant is breathing is determined not to be suitable for deep breathing. If yes, the process proceeds to step S209.

  In step S209, a respiratory support suppression process is performed by the control function. For example, the control function operates the seat back movable device 100 so that the inclination angle of the seat back 2 becomes the angle before the breathing support, and the seat lumbar movable device 200 so that the protrusion amount of the actuator 210 becomes zero. Then, the operations of the seat back movable device 100 and the seat lumbar movable device 200 are stopped. Furthermore, the breathing support operation lamp is blinked and the liquid crystal monitor is informed that the air quality is poor, thereby notifying the occupant that the air quality is poor via the information providing device 500. Further, the control function presents the breathing timing via the information providing device 500 in a state where the operations of the seat back movable device 100 and the seat lumbar movable device 200 are stopped. Accordingly, as shown in FIG. 7C, the expiration time and the inspiration time are the same as the target value, but the expiration and the inhalation amount are smaller than the target value (breathing is shallow). Can be carried out by the crew. In step S209, after the respiration support control process ends, the process proceeds to step S207.

  On the other hand, if it is determined in step S208 that the air quality of the air that the occupant breathes is suitable for deep breathing, the process proceeds to step S210. Steps S210 to S219 are performed in the same manner as steps S103 to S112 of the first embodiment. In addition, about the process of step S210-S219, since it is the same as that of step S103-S112 of 1st Embodiment, description is abbreviate | omitted.

  As described above, in the second embodiment, in addition to the effects of the first embodiment, it is determined whether or not the air that the occupant breathes is suitable for the occupant's breathing. Interrupts the occupant's breathing support and suppresses the occupant's breathing support if it is not suitable for deep breathing. Thereby, when the air which breathes has deteriorated, it can prevent effectively that a human body is adversely affected by respiration support. In the second embodiment, even when the air quality of the air that the occupant breathes is not suitable for breathing or deep breathing, the air quality of the air that the occupant breathes is repeatedly determined. When it becomes suitable for deep breathing, it is possible to immediately support the occupant's breathing appropriately.

  Further, in the second embodiment, the seat back movable device 100 and the seat lumbar movable device 200 according to the degree of air quality of the air that the occupant is breathing (for example, suitable for breathing or suitable for deep breathing). By controlling the movement of the occupant, it is possible to appropriately support the occupant's breathing in consideration of the degree of influence on the occupant's body according to the air quality of the air that the occupant is breathing.

  Furthermore, in the second embodiment, when it is determined that the air quality of the air that the occupant breathes is not suitable for deep breathing, the information of the seatback movable device 100 and the seat lumbar movable device 200 is stopped and the information is stopped. The breathing time and the breathing time targeted by the occupant are presented via the providing device 500. As a result, as shown in FIG. 7C, the expiration time and the inspiration time are slowed in the same manner as the target value, and the breathing amount and the inhalation amount are smaller (shallow) than the target value, and the occupant is breathed. Can be made. As a result, when the air quality of the air that the occupant breathes is suitable for deep breathing, the occupant's breathing state can be smoothly shifted to the breathing state corresponding to the target value.

  The embodiment described above is described for facilitating understanding of the present invention, and is not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

  For example, in the above-described embodiment, the configuration in which the operation amounts of the seat back movable device 100 and the seat lumbar movable device 200 are determined based on the air ventilation amount set in advance according to the breathing support mode is exemplified. For example, a seat back movable switch (not shown) and a seat lumbar movable switch (not shown) are provided in the vicinity of the seat, and the operation of the seat back movable device 100 is performed by an occupant operating these switches. The amount and the operation amount of the seat lumbar movable device 200 may be set.

  Further, in the above-described embodiment, the seat back movable device 100 and the seat lumbar movable device 200 may be operated during the target expiration time or the target inspiration time, or the passenger's preference, physical ability, etc. Accordingly, the operation speed of the seat back movable device 100 and the seat lumbar movable device 200 is increased, and the seat back movable device 100 and the seat lumbar movable device 200 are operated in a time shorter than the target expiration time or the target inspiration time. May be.

  Furthermore, in the above-described embodiment, the configuration in which the seat back movable device 100 and the seat lumbar movable device 200 are operated simultaneously is exemplified, but the present invention is not limited to this configuration, and the seat back movable device 100 or the seat lumbar movable device 200 Alternatively, only one of them may be operated. The seat back movable device 100 and the seat lumbar movable device 200 may be configured to operate at different times (asynchronously). Furthermore, the seat back movable device 100 and the seat lumbar movable device 200 may be configured to operate at different operation times and operation speeds.

  In the above-described embodiment, the configuration in which the breathing of the occupant is supported by operating the seat back movable device 100 and the seat lumbar movable device 200 to change the posture of the occupant is illustrated. In accordance with the operations of the seat back movable device 100 and the seat lumbar movable device 200, the timing of breathing and the length of breathing are advised by voice or the like via the information providing device 500 to assist the occupant's breathing. It is good also as a structure. In particular, when the host vehicle is running, or when the host vehicle is accelerating / decelerating or steering, the voice information “inhale and exhale” via the speaker of the information providing apparatus 500. Alternatively, it is possible to more effectively support the breathing of the occupant by providing a human breathing sound (for example, “He” for inhalation and “Foo” for exhalation) by voice or the like.

  Furthermore, in the above-described embodiment, the degree of divergence between the current breathing state of the occupant and the breathing state targeted by the occupant is expressed as divergence degree = (breathing state targeted by the occupant) / (current breathing state of the occupant). Although the structure to calculate was illustrated, it is not limited to this structure, For example, it is good also as a structure calculated as divergence degree = (passenger's present respiratory state) / (respirator's target respiratory state). In this case, when the divergence degree is equal to or less than a predetermined value, the intermediate value is calculated.

  In the above-described embodiment, the divergence degree is calculated when the host vehicle is traveling, and the intermediate value is calculated when the divergence degree is equal to or greater than a predetermined value. However, the present invention is limited to this structure. For example, the intermediate value may be generated even when the host vehicle is stopped. In addition, in this case, since it may be assumed that the timing for obtaining an effect such as stress reduction by breathing support is delayed by generating the intermediate value, for example, the information is provided to the occupant via the information providing apparatus 500. It is good also as a structure to confirm.

  Furthermore, in 2nd Embodiment mentioned above, although the structure which detects air quality using onboard sensors, such as a carbon gas sensor, an exhaust gas sensor, a dust sensor, or an oxygen concentration sensor, was illustrated, It is limited to this structure. Instead, for example, an external device such as a smartphone or a wristwatch-type air quality sensor may be used to acquire air quality information announced by the government or local government via Wi-Fi or the like. Or it is good also as a structure which acquires the information of the air quality which vehicles other than the own vehicle measured from other vehicles via an internet line or a telephone line network.

  In addition, in the second embodiment described above, the occupant breathes when the detection result by the carbon gas sensor, the exhaust gas sensor, the dust sensor, the temperature sensor, the humidity sensor, the odor sensor, or the oxygen concentration sensor exceeds a predetermined value. However, the predetermined value is not particularly limited. For example, when the environmental standards are changed in the future, the predetermined value is not changed. A predetermined value may be set according to the environmental standard. Moreover, it can also be set as the structure which detects that allergens, such as pollen, and air quality has deteriorated also when allergens are more than predetermined value.

  Note that the breathing state detection device 600 of the above-described embodiment is the breathing state detection means of the present invention, the seat back movable device 100 and the seat lumbar movable device 200 are the movable means of the present invention, and the control function of the control device 700 is the present invention.
