<< Outline of the condition correction unit according to this embodiment >>
First, the outline of the condition correction unit (hereinafter, simply condition correction unit 1) according to the present embodiment will be described. The condition correction unit 1 is mounted in the vehicle and is used for the purpose of gradually improving the health condition of the occupant of the vehicle seat S. More specifically, the condition correction unit 1 corrects the posture of the seat occupant, that is, the bent state of the spine while the seat occupant is seated on the vehicle seat S. In the present embodiment, the posture correction by the state correction unit 1 is to be carried out continuously rather than sporadically, and proceeds according to a preset plan (correction plan).

Specifically, a plurality of candidates are prepared for the correction plan, and one correction plan is selected from among them. The condition correction unit 1 performs posture correction according to the correction content indicated by the selected correction plan. Here, the "correction content" is a specific content related to posture correction, for example, a part of the body of a seated person to which a load is applied during posture correction, and a load balance between parts when a load is applied to a plurality of parts. , The correction period, the final target posture (specifically, the ideal posture described later), the standard magnitude of the load at the time of correction, and the like.

Then, in the present embodiment, the individuality of the seated person is to be reflected in the selection of the correction plan. As a result, in the present embodiment, the posture correction suitable for the individuality of the seated person is carried out. This point is a feature of the present embodiment, and the feature will be described in detail later.

In the present embodiment, the condition correction unit 1 is mounted on a seat corresponding to the driver's seat in the vehicle seat S. That is, the state correction unit 1 is used to correct the posture of the driver. However, the present invention is not limited to this, and the condition correction unit 1 may be mounted on a seat other than the driver's seat (for example, a seat for an auxiliary seat or a seat for a rear seat).

<< Configuration example of condition correction unit >>
First, in explaining the configuration example of the condition correction unit 1, the configuration of the vehicle seat S on which the condition correction unit 1 is mounted will be described. As shown in FIG. 1, the vehicle seat S includes a seat back S1 that supports the back of the seated person from behind, a seat cushion S2 that supports the buttocks of the seated person from below, and a headrest S3 that supports the head of the seated person from behind. And have. Since the basic configuration of each part of these sheets is a known configuration, description thereof will be omitted.

Next, a configuration example of the state correction unit 1 will be described. The condition correction unit 1 is composed of devices arranged inside or around the vehicle seat S described above. More specifically, the condition correction unit 1 has a device (corresponding to a moving portion) that is installed in the vehicle seat S and operates to correct the posture of the seated person.

Explaining the moving portion in detail, the seat back S1 of the vehicle seat S has a plurality of supporting portions provided with the moving portion. More specifically, as shown in FIG. 1, the seat back S1 is provided with a shoulder support portion 11, a lumbar support portion 12, a Pervis support portion 13, and a side support portion 14.

The shoulder support portion 11 is a shoulder portion of a seat seated person (strictly speaking, a standard body type seat seated person, the same shall apply hereinafter in this paragraph) seated on the vehicle seat S in the seat back S1. It is a portion that supports the above, and is provided in pairs on the left and right as shown in FIG. The lumbar support portion 12 is a portion of the seat back S1 that supports the lumbar region of the seated person, and is provided on the lower portion of the seat back S1 as shown in FIG. The Pervis support portion 13 is a portion of the seat back S1 that supports a portion of the body of the seated person where the pelvis is located, and is provided below the lumbar support portion 12 as shown in FIG. The side support portion 14 is a portion that is addressed to the body of the seated person from the side, and is inside a portion (bank portion) formed by raising both ends in the width direction in the seat back S1 as shown in FIG. It is provided.

Each of the four support units described above has an air bag. More specifically, as shown in FIG. 2, the shoulder support portion 11 is provided with an air bag for the shoulder portion 11a, the lumbar support portion 12 is provided with an air bag for the lumbar region 12a, and the pelvis support portion 13 is provided for the pelvis. An air bag 13a is provided. Although not shown in FIG. 2, an air bag is also provided in the side support portion 14.

Each air bag is arranged inside the seat back S1 or in front of the seat back S1. Then, each air bag swells when air is sealed. Such swelling of each air bag corrects the posture of the seat seater. More specifically, when each air bag swells while the seat occupant is seated on the vehicle seat S, the air bag presses the seat occupant from the back side. The pressing force corrects the posture of the seated person. Incidentally, the pressing force generated by the swelling of the air bag corresponds to the load acting on the seated person at the time of posture correction (correction load).

Further, the air is supplied to each air bag by the actuator 18 illustrated in FIG. The air supplied from the actuator 18 passes through a tube (not shown) forming an air supply path and is sealed in each air bag. Further, at a position in front of each air bag, a solenoid valve V for adjusting the amount of air filled in the air bag is installed for each air bag. The actuator 18 and the solenoid valve V as described above together with the air bag constitute the "operating unit" of the present invention.

In the present embodiment, an air bag that swells and swells when air is sealed is used as a pressing means that swells and presses the seated person. However, when a fluid other than air, for example, a liquid is sealed, the bag is used. A bulging bag may be used. Further, the seat is not limited to the one that bulges when the seat seater is pressed, such as an air bag or a bag body, and the seat is pressed by pressing a standard member such as a roller-shaped body, a ball-shaped body, or a block-shaped body. The seated person may be pressed.

Further, in the present embodiment, as shown in FIG. 1, a heater 15 and a vibration applying device 16 are provided as auxiliary mechanisms for effectively performing posture correction by the air bag. The heater 15 corresponds to a heating portion and heats a predetermined part of the body of the seat seated person seated on the vehicle seat S. By providing the heater 15, it is possible to warm the body of the seated person from the back side at the time of posture correction. By warming the seat occupant's body from the back side in this way, the responsiveness (easiness of being pressed) of the air bag to the pressing force (load) of the seat occupant's body is improved, and as a result, the posture correction is improved. It will be easy to do.

The vibration applying device 16 corresponds to a vibration applying portion, and applies vibration to a predetermined portion of the body (strictly speaking, the back portion) of the seat seated person seated on the vehicle seat S. By providing the vibration applying device 16, it is possible to apply vibration to the back of the seated person at the time of posture correction to relax the tension (muscle tension) of the back. As a result, the responsiveness (easiness of being pressed) of the air bag to the pressing force (load) of the body of the seated person is improved, and as a result, the posture correction can be performed more easily.

In the present embodiment, the vibration applying device 16 is used to relax the tension of the seat seater, but the use of the vibration applying device 16 is not limited to the above contents. For example, the vibration applying device 16 may be used for the purpose of strengthening the muscle strength of the back of the seated person. Further, the vibration imparting device 16 can also be used as an application for increasing the arousal level when the arousal level of the seated person is decreasing (for example, when the person is in a dozing state).

On the other hand, as shown in FIG. 2, the state correction unit 1 includes a control device for controlling the above-mentioned operating unit (strictly speaking, the actuator 18 and the solenoid valve V). This control device includes an ECU (Electronic Control Unit) 41 mounted in the vehicle. A control circuit for posture correction is incorporated in the ECU 41. Then, when the ECU 41 controls the on / off of the actuator 18 and the opening degree of the solenoid valve V through the control circuit for posture correction, the swelling pressure of each air bag is adjusted. As a result, a pressing force (load) corresponding to the bulging pressure of each air pressure is applied to the back of the seat occupant, and the posture of the seat occupant is corrected.

Further, the ECU 41 acquires the measured values of the various sensors by communicating with various sensors installed in the vehicle through the in-vehicle network. In other words, the ECU 41 can measure the current values of various management items by cooperating with various sensors in the vehicle. The management items (that is, measurement targets) measured by the ECU 41 include items related to the seated state of the seated person.

More specifically, the sensors for measuring the seated state of the seated person include a breathing sensor 31, a bulging pressure sensor 32, a pressure sensor 33, and a weight sensor 34. These sensors are used in a state of being attached to the vehicle seat S.

Explaining each sensor, the bulging pressure sensor 32 and the pressure sensor 33 are both sensors installed to identify the physical condition of the seated person, specifically, the sitting posture. The swelling pressure sensor 32 is installed for each air bag in order to measure the current value of the swelling pressure of the air bag. Like the swelling pressure sensor 32, the pressure sensor 33 is installed separately for each air bag, and specifically, as shown in FIG. 2, it is attached to the front surface of each air bag. Then, the ECU 41 measures the current value of the index for identifying the seating posture of the seating person through each bulging pressure sensor 32 and each pressure sensor 33 while the seating person is seated on the vehicle seat S. To do.

More specifically, in the present embodiment, in the stage before the seat seater is seated on the vehicle seat S, each of the plurality of air bags (specifically, the shoulder air bag 11a, the waist air bag 12a, and the like). The pelvic air bag 13a) is supposed to swell until it reaches a preset swelling pressure. When a seated person sits on the vehicle seat S in such a state, the swelling pressure of each air bag changes. The ECU 41 measures the swelling pressure after the change through the swelling pressure sensor 32 for each air bag. Here, the swelling pressure of each air bag (in other words, the balance of the swelling pressure between the air bags) becomes a value according to the seating posture of the seat seater. That is, the ECU 41 measures the current value of the swelling pressure of each air bag that changes when the seat seater sits on the vehicle seat S as an index for specifying the seating posture of the seat seater. ing.

As described above, in the present embodiment, the air bag is used for posture correction and also for measuring the seated state of the seated person, and the air bag is used more effectively.

Further, when the seated person is seated on the vehicle seat S, the ECU 41 measures the current value of the pressure applied to the seat back S1 through the pressure sensor 33 provided for each air bag. Specifically, when the seat seater sits on the vehicle seat S and leans against the seat back S1, when pressure is applied to the front surface of the air bag from the back of the seat seater, the pressure sensor 33 applies the pressure. The pressure sensor 33 measures the magnitude of the detected pressure by the ECU 41. Here, the pressure measured for each air bag changes depending on the installation location of the air bag. Further, the balance of pressure between the air bags becomes a value according to the sitting posture of the seated person. That is, the ECU 41 is supposed to measure the current value of the pressure when the seat occupant is seated on the vehicle seat S as an index for specifying the seating posture of the seat occupant.

As described above, in the present embodiment, two indexes (specifically, the bulging pressure of the air bag and the pressure applied to the seat back S1) are measured in specifying the seating posture of the seated person. There is. This makes it possible to more appropriately specify the sitting posture as compared with the case where only one of the above two indexes is measured. More specifically, when trying to specify the sitting posture by measuring only the bulging pressure of the air bag, it is decided to measure the bulging pressure changed by the seat seater sitting on the vehicle seat S. Become. However, even if the swelling pressure changes, it may be difficult to determine whether it is due to seat seating or for some other reason (for example, air filling in an air bag). On the other hand, when the pressure sensor 33 measures only the pressure applied to the seat back S1 to specify the seating posture, if the back of the seat seater does not properly hit the portion of the seat back S1 where the air bag is located, the pressure is increased. The measurement by the sensor 33 cannot be performed accurately.

On the other hand, in the present embodiment, since two indexes are measured for specifying the seating posture of the seat seated person, the seat seated person is more appropriately compared with the case where only one of the above indexes is measured. It is possible to specify the sitting posture of. However, the present invention is not limited to this, and only one of the two indicators may be measured.

Further, the ECU 41 measures a sitting state other than the sitting posture by using the breathing sensor 31 and the weight sensor 34. Specifically, the ECU 41 identifies the awake state of the seat seated person by using the breathing sensor 31 composed of the pressure-sensitive resistance type sensor installed at the rear end of the seat cushion S2. More precisely, the ECU 41 measures the periodic sitting pressure fluctuation (respiratory waveform) linked to the respiration of the seat seat with the respiration sensor 31, and identifies the awake state of the seat seater from the measured value. Further, the ECU 41 measures the load acting on the vehicle seat S using the weight sensor 34, and identifies the presence or absence of a seat seater from the measured value.

Further, the ECU 41 acquires the measured value of the in-vehicle sensor by communicating with the in-vehicle sensor other than the above-mentioned sensor through the in-vehicle network, and for example, by communicating with the vehicle speed sensor 42, the current value of the traveling speed (vehicle speed) is obtained. get.

Furthermore, the ECU 41 can acquire information from the communication device by communicating with a communication device other than the above in the vehicle through the in-vehicle network. More specifically, the ECU 41 acquires information about the seated person (strictly speaking, identification information described later) by communicating with the smartphone 44 as a mobile terminal possessed by the seated person. Further, the ECU 41 communicates with the car navigation device 43 to acquire information on the planned distance and the planned route on which the vehicle will travel on that day.

Furthermore, in the ECU 41, the vehicle is ETC (Electronic).
By communicating with the ETC 47 when passing in front of the Mall Collection) 47, information for identifying the vehicle's driving location (strictly speaking, information indicating whether the vehicle is traveling on the highway) is acquired. ..

Furthermore, the ECU 41 can be connected to a portable memory 45, which is a portable recording medium such as a USB memory or an SD card (registered trademark), and can transfer data to and from the portable memory 45. Is. That is, the ECU 41 can write the information stored by itself to the portable memory 45, while reading the information stored in the portable memory 45.

Furthermore, the ECU 41 can communicate with the tablet terminal provided in the vehicle (hereinafter, the tablet terminal 46 in the vehicle) and display the information on the monitor screen (corresponding to the screen) of the tablet terminal 46 in the vehicle. More specifically, the in-vehicle tablet terminal 46 is arranged around the vehicle seat S (strictly speaking, a position that is easy for the seated person to operate), and stands up from the vehicle body floor as shown in FIG. It is set on the top of the stanchion that is set up.

Then, the ECU 41 generates data (information display data) for displaying image information and character string information, and transmits the information display data to the in-vehicle tablet terminal 46. When the in-vehicle tablet terminal 46 receives the information display data through the in-vehicle network, it expands the information display data and displays the information indicated by the data on the monitor screen. As a result, the seated person can check various information transmitted from the ECU 41 on the monitor screen, and for example, as shown in FIG. 4, it is possible to check the seated state measured by the ECU 41. Become.

Incidentally, the screen example shown in FIG. 4 is merely an example of a monitor screen, and its design and screen layout are not limited to those shown in FIG. 4, and can be set arbitrarily. Further, in FIG. 4, information on the respiratory state (strictly speaking, the respiratory waveform and the arousal degree determination graph), information on the pelvic angle (strictly speaking, the change curve of the pelvic angle and the fatigue level determination graph), and the inclination of the vehicle body. (Indicated as vehicle body G in the figure) is displayed as a seated state, but the information displayed on the monitor screen is not limited to the above contents.

The monitor screen of the in-vehicle tablet terminal 46 is composed of a touch panel 46a, displays information indicated by information display data, and accepts screen operations (touch operations) performed by a seated person as input operations.

<< About the function of the control device >>
Next, the function of the ECU 41 as a control device will be described with reference to FIG. The ECU 41 implements various functions related to posture correction. Specifically, as shown in FIG. 4, the ECU 41 includes an identification information acquisition unit 51, a measurement unit 52, a plan storage unit 53, a presentation unit 54, a processing execution unit 55, a total seating time management unit 56, and an aspect setting unit. It has 57, a comparison unit 58, an information display unit 59, a determination unit 60, an information transfer unit 61, an information reading unit 62, and a plan changing unit 63. Each of these functional units is realized by the hardware equipment (specifically, the MPU and the memory) constituting the ECU 41 cooperating with the software equipment (control circuit for attitude control).

Hereinafter, each of the above functional units will be described. It should be noted that the order of description of each functional unit in the following is different from the posting order of the functional units described above.

(Identification information acquisition unit 51)
The identification information acquisition unit 51 acquires the identification information of the seated person. Here, the identification information is information for identifying (individual authentication) a seat occupant, for example, ID information of the seat occupant, image information showing a face image or fingerprint image of the seat occupant, and a seat occupant. Voiceprint information, etc.

By the way, in the present embodiment, the identification information acquisition unit 51 acquires the identification information from the smartphone 44 by communicating with the smartphone 44 possessed by the seated person. With such a configuration, when a person who owns the smartphone 44 sits on the vehicle seat S, the ECU 41 automatically acquires the identification information of the seated person by communicating with the smartphone 44. As a result, in the present embodiment, it is possible to relatively easily acquire the identification information of the seated person.

The method of acquiring the identification information is not limited to the above method, and the seated person inputs the identification information through the in-vehicle tablet terminal 46 or a predetermined input device, and the ECU 41 receives the input operation from the device. The identification information may be acquired by receiving data related to the identification information (contents of the input operation). Alternatively, the identification information may be acquired by taking a face image of the seat occupant with a camera installed in the vehicle or recording the voice of the seat occupant with a microphone installed in the vehicle. Alternatively, a sensor for identifying the seated person may be installed in the vehicle (for example, near the steering wheel), and the ECU 41 may acquire identification information (sensor detection result) from the sensor.

(Measuring unit 52)
The measuring unit 52 measures the physical condition of the seated person when seated on the vehicle seat S, that is, the seated state, by using the sensor group for measuring the seated state provided in the vehicle. Specifically, the measuring unit 52 uses the swelling pressure sensor 32 provided for each air bag to measure the current value of the swelling pressure of each air bag that changes when the seated person sits on the vehicle seat S. Measure. Further, the measuring unit 52 measures the current value of the pressure applied to each part of the seat back S1 when the seated person is seated on the vehicle seat S by the pressure sensor 33 attached to the front surface of each air bag. In addition, the measuring unit 52 measures the respiration waveform of the seated person by the respiration sensor 31. Further, the measuring unit 52 measures the load acting on the vehicle seat S by the weight sensor 34.

The measurement target and the measurement method by the measurement unit 52 may be measured by a suitable method as an index for specifying the physical condition of the seated person, and is not limited to the above contents. For example, the skeleton shape of the seated person may be measured by a known shape sensor. Alternatively, the seated person may be photographed with a camera in the vehicle, and the photographed image may be analyzed to measure the degree of bending of the spine of the seated person, the distortion of the skeleton, and the like.

As described above, the measuring unit 52 measures the seated state of the seated person (specifically, the current value of the bulging pressure of each air bag and the pressure applied to the seat back S1), but in the present embodiment, the same seat is used. The seated person (that is, the seated person having the same identification information) is to be measured over a plurality of measurement days. More specifically, when a person uses the vehicle on different days, the measuring unit 52 measures the seated state of the person on a daily basis.

The daily measured value by the measuring unit 52 is to be stored as a measurement history. This measurement history is associated with the identification information of the seat occupants and is managed for each seat occupant.

(Judgment unit 60)
The determination unit 60 is an index for specifying the sitting posture (specifically, the bulge pressure measured by the bulge pressure sensor 32 and the pressure sensor) among the current values related to the seating state measured by the measurement unit 52. The sitting posture (bending state of the spine) is determined from the current value of the pressure (pressure measured at 33). More specifically, the determination unit 60 selects the corresponding one from the five postures of "cat back", "slightly cat back", "ideal posture", "slightly warped back" and "warped back", and the selection result. Is the current seating posture of the seated person.

In addition, it is possible to arbitrarily set which of the above five sitting postures corresponds to when the current value (that is, the measured value) of the index measured by the measuring unit 52 is in the range. .. Further, the candidates for the sitting posture are not limited to the above five postures, and can be arbitrarily determined.

<< Operation example of condition correction unit >>
Next, as an operation example of the state correction unit 1, the flow of posture correction (posture correction flow) by the state correction unit 1 will be described.
The posture correction flow is mainly divided into a flow when the seated person receives the posture correction for the first time (hereinafter, the flow at the first time) and a flow after the first time (hereinafter, the flow at the normal time). In the following, the initial flow will be described first, and then the normal flow will be described.

(First time flow)
The initial flow proceeds according to the flow shown in FIGS. 10 and 11. Specifically, when the seated person first sits on the vehicle seat S according to the present embodiment, the initial flow is automatically started (S001). More specifically, when the seated person is seated on the vehicle seat S, the weight sensor 34 outputs a signal according to the magnitude of the seat weight that changes accordingly. When the ECU 41 receives the output signal from the weight sensor 34, the ECU 41 automatically starts the main process (processes after step S002) of the initial flow by using this as a trigger. In the present embodiment, the initial flow is automatically started when the seat seater is seated on the vehicle seat S, but the present invention is not limited to this, and the seat seater is seated. A predetermined operation / operation may be performed later, and the initial flow may be started with such an operation / operation as a trigger.

When the flow at the first time is started, the ECU 41 (specifically, the measuring unit 52) performs various measurements including the measurement regarding the seated state of the seated person (S002). Specifically, the swelling pressure of each air bag is measured by the swelling pressure sensor 32, the pressure applied to each part of the seat back S1 is measured by the pressure sensor 33, and the sitting pressure that changes with respiration is measured by the respiration sensor 31. Measure at. In measuring the swelling pressure of each air bag, the ECU 41 controls the actuator 18 and the solenoid valve V before the seat seater sits on the vehicle seat S, and makes each air bag have a predetermined swelling pressure. Inflate until

After that, the ECU 41 (specifically, the identification information acquisition unit 51) acquires the identification information of the seat occupant from the smartphone 44 by communicating with the smartphone 44 possessed by the seat occupant (S003). Further, the ECU 41 (specifically, the determination unit 60) determines the seating posture of the seated person from the seated state measured in step S002 (S004). More specifically, in the ECU 41, the current sitting posture of the seat seater is "cat back", "cat back", based on the current value of the bulging pressure of the air bag and the current value of the pressure applied to each part of the seat back S1. Determine which of "slightly stooped", "ideal posture", "slightly warped back", and "warped back".

Then, the ECU 41 (specifically, the information display unit 59) generates information display data for displaying the determined sitting posture and transmits it to the in-vehicle tablet terminal 46. As a result, the seating posture determination result is displayed on the touch panel 46a of the in-vehicle tablet terminal 46 (S005).

After that, the ECU 41 carries out the subsequent steps according to the determination result of the sitting posture. Specifically, when the determined sitting posture is the ideal posture (Yes in S006), the ECU 41 ends the initial flow. On the other hand, when the determined sitting posture is a posture other than the ideal posture (No in S006), the ECU 41 carries out the subsequent steps triggered by the mode designation operation of the seat seater.

Here, the mode designation operation by the seated person will be described. The mode designation operation is an operation performed to specify one of a plurality of candidates prepared for the control mode of the ECU 41, and in the present embodiment, the mode designation operation is performed. This is done through the touch panel 46a of the in-vehicle tablet terminal 46. Two candidates are prepared as the control mode by the ECU 41, and specifically, the "comfort correction" mode and the "ideal correction" mode are set. The "ideal correction" mode is a mode for correcting the posture, and specifically, a mode for controlling the actuator 18, the solenoid valve V, and the like so as to correct the current sitting posture so as to have the ideal posture.

The "comfort correction" mode is a mode for stabilizing the current sitting posture, and is a mode for controlling the actuator 18, the solenoid valve V, etc. so that the seat seater can easily maintain the current sitting posture. is there.

The seat seater has two designation buttons (“comfort correction” and “ideal” in FIG. 7) displayed together with the seating posture determination result on the touch panel 46a in order to specify one of the above two control modes. Press one of the buttons with the letters "Correction"). Such a button operation is a mode designation operation, and the ECU 41 accepts the operation via the in-vehicle tablet terminal 46.

Then, when the mode of "comfort correction" is specified ("comfort correction" in S007), the ECU 41 performs the above-mentioned comfort correction (S008).

On the other hand, when the "ideal correction" mode is specified ("ideal correction" in S007), the ECU 41 performs the above-mentioned ideal correction. In carrying out the ideal correction, the ECU 41 (specifically, the presentation unit 54) accesses the plan storage unit 53, and the sheet determined in the previous step S004 from the correction plans stored in the plan storage unit 53. Read the correction plan according to the seated person's current sitting posture. Then, the ECU 41 presents the read-out correction plan to the seated person (S009). More specifically, the ECU 41 (specifically, the information display unit 59) generates information display data for displaying the read correction plan and transmits it to the in-vehicle tablet terminal 46. As a result, as shown in FIG. 8, the correction plan read by the ECU 41, that is, the correction plan according to the current sitting posture of the seated person is displayed on the touch panel 46a of the in-vehicle tablet terminal 46.

Further, the ECU 41 associates the seated person identification information acquired in the previous step S003 with the presented correction plan and stores it in the plan storage unit 53 (S010). Specifically, the plan management table T is updated so that a record in which the identification information and the correction plan are associated with each other is added to the plan management table T.

After that, when the seated person issues a command to execute the ideal correction on the in-vehicle tablet terminal 46 (specifically, when the button with the characters "correction start" is pressed in FIG. 8), this is used as a trigger. The ECU 41 performs the ideal correction (S011). The ideal correction proceeds when the ECU 41 carries out each step shown in FIG.

Specifically, in the ideal correction, the ECU 41 (specifically, the processing execution unit 55) provides a correction plan associated with the identification information of the seat seater seated on the vehicle seat S in the plan storage unit 53. Read from (S021).

Next, the ECU 41 (specifically, the processing execution unit 55) controls the heater 15 to heat a predetermined portion of the back of the seat seater (S022), and controls the vibration imparting device 16 to seat the seat. Vibration is applied to the back of the person (S023). As a result, the muscles of the seated person (particularly the muscles of the shoulders, back, and hips) are softened, and the subsequent posture correction can be performed efficiently.

After that, the ECU 41 (specifically, the mode setting unit 57) sets the straightening mode to be applied at the time of the straightening process (S024). Explaining the procedure for setting the correction mode, as shown in FIG. 13, the total number of seated persons who are seated on the vehicle seat S at that time by the ECU 41 (specifically, the total seating time management unit 56) The seating time is specified (S031). At the stage immediately after the start of the flow at the first time, the total seating time is 0.

After that, the ECU 41 (specifically, the mode setting unit 57) specifies the day of the week and the current time zone of the day (S032). Further, the ECU 41 (specifically, the mode setting unit 57) identifies the planned travel distance of the vehicle on that day by communicating with the car navigation device 43 (S033). Further, the ECU 41 (specifically, the mode setting unit 57) specifies the current traveling location of the vehicle, more specifically, whether or not the vehicle is traveling on the highway, based on the signal received from the ETC 47 or the like. (S034). Further, the ECU 41 (specifically, the mode setting unit 57) specifies the age of the seat occupant input by the seat occupant through the in-vehicle tablet terminal 46 (S035). After completing these series of specific steps, the ECU 41 (specifically, the mode setting unit 57) sets the correction mode according to the specific result in each of the steps S031 to S035 up to that point (S036).

After setting the correction mode, the ECU 41 (specifically, the processing execution unit 55) executes the correction processing in the correction mode set in the previous step S036 according to the correction content indicated by the correction plan read in the previous step S021. (S025).

Then, as shown in FIG. 12, the ECU 41 (specifically, the process execution unit 55) has a step of setting the correction mode, a step of executing the correction process, and a step of executing the correction process until the correction end condition is satisfied (S026). Is repeated regularly. The correction end condition defines the timing for ending the execution portion (one day's worth) of the ideal correction. For example, the correction time specified in advance has elapsed, and the vehicle is the destination. It is possible to arrive at the or to perform an operation for the seated person to instruct the end of the correction.

Then, when the correction end condition is satisfied, the posture correction for the first time is completed, and the flow at the first time is finished.

(Normal flow)
The normal flow is to be performed after the day when the initial flow is performed, and proceeds according to the flow shown in FIG. More specifically, the normal flow is automatically started when the seated person is seated on the vehicle seat S (S041), as in the initial flow. After that, the ECU 41 performs various measurements (S042) regarding the seating state of the seat seater, acquisition of the seat seater identification information (S043), and determination of the seating posture (S044) in the same procedure as the initial flow. I do.

As described above, in the present embodiment, the ECU 41 is supposed to measure the sitting state, acquire the identification information, and determine the sitting posture as a common routine of the initial flow and the normal flow. Then, when the acquired identification information matches the previously acquired identification information, the ECU 41 will subsequently perform the normal flow according to the procedure shown in FIG. It should be noted that the fact that the normal flow is performed means that the seating state is measured and the sitting posture is determined for a seated person having the same identification information over a plurality of days. In other words, in the normal flow, the seating posture of the seat seater is measured again after the day when the first flow is performed.

After the seating posture is determined in the normal flow, the ECU 41 (specifically, the comparison unit 58) performs a posture comparison (S045). Specifically, in the posture comparison, the measured value of the seated state in the initial flow (first measured value) and the measured value of the seated state measured this time in the normal flow (current measured value) are compared. ..

After that, the ECU 41 (specifically, the information display unit 59) generates information display data for displaying the result of the posture comparison and transmits it to the in-vehicle tablet terminal 46. As a result, as shown in FIG. 9, the comparison result of the sitting posture, specifically, the image information corresponding to each of the current measurement value and the first measurement value is displayed on the touch panel 46a of the in-vehicle tablet terminal 46. Becomes (S046). As a result, the seated person can grasp the effect (posture improvement condition) of the posture correction performed up to the previous time through the touch panel 46a.

On the other hand, the ECU 41 (specifically, the plan change unit 63) is a correction plan applied when correcting the posture of the seat seater (strictly speaking, the seat seater who is seated on the vehicle seat S at that time). Whether or not to change is determined according to the comparison result in the previous step S046. Specifically, the correction condition for the sitting posture of the seat seater is specified from the comparison result, and if the correction condition is above a certain level (Yes in S047), the plan is not changed. .. In such a case, the ECU 41 continues to apply the correction plan associated with the identification information to the ideal when performing the ideal correction (that is, posture correction) for the seat seated person having the same identification information. The correction will be carried out (S048).

On the other hand, when the correction condition is less than a certain level (No in S047), the ECU 41 (specifically, the presentation unit 54) is selected from the correction plans stored in the plan storage unit 53 at that time. The correction plan corresponding to the correction condition of the above is read out, and the correction plan is presented to the seat seater as a new correction plan (S049). Then, the ECU 41 (specifically, the plan change unit 63) changes the correction plan associated with the identification information of the seat seated person to which the new correction plan is presented (S050). Specifically, the plan management table T is updated so that the above plan change is reflected. Then, the ECU 41 (specifically, the processing execution unit 55) performs ideal correction (that is, posture correction) in the changed correction plan (S051).

In the normal flow, the ideal correction proceeds in the same procedure as the initial flow (that is, the procedure shown in FIG. 12). Further, even in the normal flow, the step of setting the correction mode and the step of executing the correction process are periodically repeated until the correction end condition is satisfied. Then, when the correction end condition is satisfied, the posture correction for that day is completed, and the normal flow ends.
