温冷刺激システムHot / cold stimulation system 関連出願への相互参照Cross-reference to related applications
　本出願は、２０１９年１２月３日に出願された日本特許出願番号２０１９－２１９１１４号に基づくもので、ここにその記載内容が参照により組み入れられる。 This application is based on Japanese Patent Application No. 2019-219114, which was filed on December 3, 2019, and the description thereof is incorporated herein by reference.
　本開示は、温冷刺激システムに関するものである。 This disclosure relates to a hot / cold stimulation system.
　特許文献１に、シートの着座者の背面側部位に対して温刺激と冷刺激とを交互に供給する温冷刺激システムが開示されている。以下では、温刺激と冷刺激とを交互に繰り返して供給することを、温冷刺激を供給するともいう。これによれば、着座者の背面側部位に対して温冷刺激を供給することで、着座者の血管の拡縮により、血流が促進される。これにより、着座者の疲労を軽減することができる。 Patent Document 1 discloses a hot / cold stimulus system that alternately supplies hot stimuli and cold stimuli to a portion of the seat on the back side of the seat. In the following, supplying hot and cold stimuli alternately and repeatedly is also referred to as supplying hot and cold stimuli. According to this, by supplying a hot / cold stimulus to the back side portion of the seated person, blood flow is promoted by expanding / contracting the blood vessels of the seated person. This makes it possible to reduce the fatigue of the seated person.
　この温冷刺激システムでは、温刺激を供給する温刺激期間と、冷刺激を供給する冷刺激期間とを一周期として、温刺激期間と冷刺激期間とが周期的に交互に繰り返される。特許文献１には、温刺激期間と冷刺激期間との比率である温冷比率を調整することが開示されている。温冷比率を調整することで、着座者に与える温冷刺激の温冷感を調整することができる。 In this warm / cold stimulation system, the warm stimulation period for supplying the warm stimulus and the cold stimulus period for supplying the cold stimulus are set as one cycle, and the warm stimulus period and the cold stimulus period are periodically repeated alternately. Patent Document 1 discloses that the hot / cold ratio, which is the ratio between the hot stimulation period and the cold stimulation period, is adjusted. By adjusting the hot / cold ratio, it is possible to adjust the hot / cold feeling of the hot / cold stimulus given to the seated person.

　ところで、本発明者の検討によると、温冷刺激の供給において、特定の温冷比率および特定の一周期とされた特定の設定に対して、温冷比率と一周期との両方を変更すると、変更前の設定と比較して、疲労軽減効果が大きく低下する場合があることが分かった。その一方で、上記の特定の設定に対して、一周期の時間を実質的に同じとして、温冷比率を変更した場合、変更前の設定と比較して、疲労軽減効果が低下しないか、疲労軽減効果が低下しても低下の割合が小さく、一定の疲労軽減効果が得られることが分かった。 By the way, according to the study of the present inventor, in the supply of hot / cold stimulus, if both the hot / cold ratio and one cycle are changed for a specific setting having a specific hot / cold ratio and a specific one cycle, It was found that the fatigue reduction effect may be significantly reduced compared to the setting before the change. On the other hand, when the hot / cold ratio is changed with the time of one cycle being substantially the same for the above specific setting, the fatigue reduction effect is not reduced or fatigue is not reduced as compared with the setting before the change. It was found that even if the reduction effect is reduced, the rate of reduction is small and a certain fatigue reduction effect can be obtained.
　しかし、特許文献１には、温冷比率を変えることが開示されているが、一周期の時間の設定の仕方についてまでは、開示されていない。本開示は、一定の疲労軽減効果を得つつ、温冷感を調整することができる温冷刺激システムを提供することを目的とする。 However, although Patent Document 1 discloses that the temperature / cooling ratio is changed, it does not disclose how to set the time for one cycle. An object of the present disclosure is to provide a hot / cold stimulus system capable of adjusting a feeling of warm / cold while obtaining a certain effect of reducing fatigue.
　上記目的を達成するため、本開示の１つの観点によれば、
　温冷刺激システムは、
　対象者に対して温刺激と冷刺激とを供給する温冷刺激装置と、
　温刺激を供給する温刺激期間と冷刺激を供給する冷刺激期間との合計を一周期として、温刺激期間と冷刺激期間とが周期的に交互に繰り返されるように、温冷刺激装置の作動を制御する刺激制御部と、
　一周期における温刺激期間と冷刺激期間との比率である温冷比率を決定する温冷比率決定部と、を備え、
　刺激制御部は、温冷比率決定部が決定する温冷比率で、温刺激期間と冷刺激期間とが交互に繰り返されるように、温冷刺激装置を作動させ、
　温冷比率決定部が決定する温冷比率には、互いに異なる第１比率と第２比率とが含まれ、
　温冷比率決定部は、第１比率のときの一周期と、第２比率のときの一周期とが、実質的に同じ時間となるように、温冷比率を決定する。 To achieve the above object, according to one aspect of the present disclosure,
The hot / cold stimulation system

Stimulus control unit that controls
It is equipped with a hot / cold ratio determining unit that determines the hot / cold ratio, which is the ratio between the hot stimulation period and the cold stimulation period in one cycle.
The stimulus control unit operates the hot / cold stimulus device so that the hot / cold stimulus period and the cold stimulus period are alternately repeated at the hot / cold ratio determined by the hot / cold ratio determining unit.

The hot / cold ratio determining unit determines the hot / cold ratio so that one cycle at the time of the first ratio and one cycle at the time of the second ratio are substantially the same time.
　これによれば、温冷比率を異ならせても、一周期の時間を実質的に同じとしているので、一定の疲労軽減効果が得られる。よって、一定の疲労軽減効果を得つつ、対象者に与える温冷感を調整することができる。 According to this, even if the hot / cold ratio is different, the time of one cycle is substantially the same, so that a certain fatigue reduction effect can be obtained. Therefore, it is possible to adjust the feeling of warmth and coldness given to the subject while obtaining a certain effect of reducing fatigue.

In each of the following embodiments, parts that are the same or equal to each other will be described with the same reference numerals.
　（第１実施形態）
　図１に示す本実施形態の温冷刺激システム１０は、車両に搭載される。温冷刺激システム１０は、温冷刺激装置２０と、制御装置３０と、作動スイッチ４１と、設定スイッチ４２とを備える。 (First Embodiment)
The heating / cooling stimulation system 10 of the present embodiment shown in FIG. 1 is mounted on a vehicle. The hot / cold stimulus system 10 includes a hot / cold stimulus device 20, a control device 30, an operation switch 41, and a setting switch 42.
　図２に示すように、温冷刺激装置２０は、車両が備える運転席のシート１０１に設けられている。温冷刺激装置２０は、シート１０１に着座する着座者の身体の背面側部位に対して、温刺激と冷刺激とを供給する。本実施形態では、着座者が、温冷刺激装置２０が温刺激と冷刺激とを供給する対象者である。温刺激は、着座者の体温よりも高温の温熱による刺激である。冷刺激は、着座者の体温よりも低温の冷熱による刺激である。 As shown in FIG. 2, the heating / cooling stimulator 20 is provided on the driver's seat 101 of the vehicle. The hot / cold stimulus device 20 supplies the hot / cold stimulus to the back side portion of the body of the seated person seated on the seat 101. In the present embodiment, the seated person is a subject to which the hot / cold stimulator 20 supplies the hot / cold stimulus. Thermal stimulation is stimulation by heat that is higher than the body temperature of the seated person. Cold stimulation is stimulation by cold heat that is lower than the body temperature of the seated person.
　図２、３に示すように、シート１０１は、着座者の臀部および大腿部を支持する着座部１０２と、その着座者の背中を支持する背もたれ部１０３とを有する。背もたれ部１０３のうち着座者が接する側が前方側である。背もたれ部のうち着座者が接する側の反対側が後方側である。背もたれ部１０３は、弾性材で構成されたシートパッド１０４と、シートパッド１０４を覆う表皮材１０５とを有する。 As shown in FIGS. 2 and 3, the seat 101 has a seating portion 102 that supports the buttocks and thighs of the seated person, and a backrest portion 103 that supports the back of the seated person. Of the backrest 103, the side that the seated person contacts is the front side. The side of the backrest that is in contact with the seated person is the rear side. The backrest portion 103 has a seat pad 104 made of an elastic material and a skin material 105 that covers the seat pad 104.
　温冷刺激装置２０は、送風機２１、シートパッド１０４に設けられた空気通路２２、シートパッド１０４の前方側部分に設けられた複数の孔部２３、シートパッド１０４と表皮材１０５との間に設置されたヒータ２４などを有している。送風機２１およびヒータ２４は、制御装置３０の出力側に接続されている。なお、温冷刺激装置２０が有する送風機２１、空気通路２２および複数の孔部２３は、シートベンチレーションシステム（以下、ＳＶＳという）を構成している。 The heating / cooling stimulator 20 is installed between the blower 21, the air passage 22 provided in the seat pad 104, the plurality of holes 23 provided in the front side portion of the seat pad 104, and the seat pad 104 and the skin material 105. It has a heater 24 and the like. The blower 21 and the heater 24 are connected to the output side of the control device 30. The blower 21, the air passage 22, and the plurality of holes 23 included in the heating / cooling stimulator 20 form a seat ventilation system (hereinafter referred to as SVS).
　温冷刺激装置２０は、ＳＶＳを用いて着座者に冷刺激を供給することが可能である。具体的には、温冷刺激装置２０が着座者に冷刺激を供給する場合、送風機２１が作動する。これにより、図２の矢印Ｃ１に示すように、車室内の空気は、表皮材１０５を介して複数の孔部２３から空気通路２２に吸い込まれる。一般に、車両走行中の車室内の温度は、空調装置の作動により、または、車室外空気の温度の影響により、着座者の体温より低温である。そのため、背もたれ部１０３の前方側の表面の温度は、着座者の体温より低温に維持される。着座者が背もたれ部１０３の前方側の表面に触れていることで、着座者の身体の背面側部位に、冷刺激が供給される。なお、複数の孔部２３から空気通路２２に吸い込まれた空気は、図２の矢印Ｃ２に示すように、空気通路２２および送風機２１を経由し、背もたれ部１０３の後方側の下部に設けられた後方側孔部２５から吹き出される。 The hot / cold stimulator 20 can supply a cold stimulus to the seated person by using SVS. Specifically, when the hot / cold stimulus device 20 supplies the cold stimulus to the seated person, the blower 21 operates. As a result, as shown by the arrow C1 in FIG. 2, the air in the vehicle interior is sucked into the air passage 22 from the plurality of holes 23 via the skin material 105. Generally, the temperature inside the vehicle while the vehicle is running is lower than the body temperature of the seated person due to the operation of the air conditioner or the influence of the temperature of the air outside the vehicle. Therefore, the temperature of the front surface of the backrest 103 is maintained lower than the body temperature of the seated person. When the seated person touches the front surface of the backrest portion 103, a cold stimulus is supplied to the back side portion of the seated person's body. As shown by the arrow C2 in FIG. 2, the air sucked into the air passage 22 from the plurality of holes 23 is provided in the lower part on the rear side of the backrest portion 103 via the air passage 22 and the blower 21. It is blown out from the rear side hole 25.
　また、温冷刺激装置２０は、ヒータ２４を用いて着座者に温刺激を供給することが可能である。具体的には、温冷刺激装置２０が着座者に温刺激を供給する場合、ヒータ２４が作動する。これにより、ヒータ２４が発熱し、その熱がシートパッド１０４および表皮材１０５に伝熱することで、背もたれ部１０３の前方側の表面の温度は、着座者の体温より高温に維持される。着座者が背もたれ部１０３の前方側の表面に触れていることで、着座者の身体の背面側部位に、温刺激が供給される。 Further, the hot / cold stimulator 20 can supply the warm stimulus to the seated person by using the heater 24. Specifically, when the warm / cold stimulus device 20 supplies the warm stimulus to the seated person, the heater 24 operates. As a result, the heater 24 generates heat, and the heat is transferred to the seat pad 104 and the skin material 105, so that the temperature of the front surface of the backrest 103 is maintained higher than the body temperature of the seated person. When the seated person touches the front surface of the backrest portion 103, a warm stimulus is supplied to the back side portion of the seated person's body.
　制御装置３０は、温冷刺激装置２０の作動を制御する。制御装置３０は、図示しないインストルメントパネルの内側の空間に設けられている。制御装置３０は、プロセッサ、メモリを含むマイクロコンピュータとその周辺回路から構成される。メモリは、非遷移的実体的記憶媒体で構成される。プロセッサが、メモリに記憶されたプログラムを実行することにより、制御装置３０は、各種演算、処理を実現する。これにより、制御装置３０は、送風機２１と、ヒータ２４とのそれぞれの作動を制御する。 The control device 30 controls the operation of the hot / cold stimulator 20. The control device 30 is provided in a space inside an instrument panel (not shown). The control device 30 is composed of a microprocessor including a processor and a memory, and peripheral circuits thereof. The memory is composed of a non-transitional substantive storage medium. When the processor executes the program stored in the memory, the control device 30 realizes various operations and processes. As a result, the control device 30 controls the operation of the blower 21 and the heater 24, respectively.
　具体的には、図４に示すように、作動スイッチ４１がＯＦＦからＯＮにされた場合、温刺激期間ｔ１と冷刺激期間ｔ２との合計を一周期ｔ３として、温刺激期間ｔ１と冷刺激期間ｔ２とが周期的に交互に繰り返されるように、制御装置３０は、温冷刺激装置２０の作動を制御する。温刺激期間ｔ１は、温冷刺激装置２０が温刺激を供給する期間である。冷刺激期間は、温冷刺激装置２０が冷刺激を供給する期間である。温刺激期間ｔ１では、ヒータ２４がＯＮの状態にされ、送風機２１がＯＦＦの状態にされる。これにより、背もたれ部１０３の前方側の表面の温度が高くなる。冷刺激期間ｔ２では、ヒータ２４がＯＦＦの状態にされ、送風機２１がＯＮの状態にされる。これにより、背もたれ部１０３の前方側の表面の温度が低くなる。 Specifically, as shown in FIG. 4, when the operation switch 41 is turned from OFF to ON, the total of the warm stimulation period t1 and the cold stimulation period t2 is set as one cycle t3, and the warm stimulation period t1 and the cold stimulation period t1 and the cold stimulation period t3. The control device 30 controls the operation of the heating / cooling stimulating device 20 so that t2 and t2 are periodically and alternately repeated. The warm / cold stimulus period t1 is a period in which the hot / cold stimulator 20 supplies the warm stimulus. The cold stimulus period is a period in which the hot / cold stimulator 20 supplies the cold stimulus. In the thermal stimulation period t1, the heater 24 is turned on and the blower 21 is turned off. As a result, the temperature of the surface on the front side of the backrest portion 103 becomes high. In the cold stimulation period t2, the heater 24 is turned off and the blower 21 is turned on. As a result, the temperature of the front surface of the backrest 103 is lowered.
　作動スイッチ４１は、温冷刺激装置２０の作動と停止とを、着座者の操作によって切り替えるスイッチである。作動スイッチ４１は、制御装置３０の入力側に接続されている。作動スイッチ４１は、図示しないインストルメントパネルに設けられている。 The operation switch 41 is a switch that switches between the operation and stop of the heating / cooling stimulator 20 by the operation of the seated person. The operation switch 41 is connected to the input side of the control device 30. The operation switch 41 is provided on an instrument panel (not shown).
　設定スイッチ４２は、一周期ｔ３における温刺激期間ｔ１と冷刺激期間ｔ２との比率である温冷比率を、着座者の操作によって切り替えるスイッチである。設定スイッチ４２は、制御装置３０の入力側に接続されている。設定スイッチ４２は、図示しないインストルメントパネルに設けられている。 The setting switch 42 is a switch that switches the hot / cold ratio, which is the ratio between the warm stimulation period t1 and the cold stimulation period t2 in one cycle t3, by the operation of the seated person. The setting switch 42 is connected to the input side of the control device 30. The setting switch 42 is provided on an instrument panel (not shown).
　図５に示すように、設定スイッチ４２は、複数の設定ボタンで構成されている。複数の設定ボタンは、第１ボタン４３、第２ボタン４４、第３ボタン４５、第４ボタン４６および第５ボタン４７を含む。各ボタン４３～４７に対応する温冷比率および一周期が、制御装置３０のメモリに予め記憶されている。 As shown in FIG. 5, the setting switch 42 is composed of a plurality of setting buttons. The plurality of setting buttons include a first button 43, a second button 44, a third button 45, a fourth button 46, and a fifth button 47. The heating / cooling ratio and one cycle corresponding to each of the buttons 43 to 47 are stored in advance in the memory of the control device 30.
　第１ボタン４３が押されたときの温刺激期間ｔ１と冷刺激期間ｔ２とのそれぞれは、図６に示すように、ｔ１１とｔ２１である。このときの温冷比率は、ｔ１１：ｔ２１＝１：３である。このときの一周期ｔ３は、６分３０秒である。 The warm stimulation period t1 and the cold stimulation period t2 when the first button 43 is pressed are t11 and t21, respectively, as shown in FIG. The hot / cold ratio at this time is t11: t21 = 1: 3. One cycle t3 at this time is 6 minutes and 30 seconds.
　第２ボタン４４が押されたときの温刺激期間ｔ１と冷刺激期間ｔ２とのそれぞれは、図７に示すように、ｔ１２とｔ２２である。このときの温冷比率は、ｔ１２：ｔ２２＝１：２である。このときの一周期ｔ３は、６分３０秒である。 The warm stimulation period t1 and the cold stimulation period t2 when the second button 44 is pressed are t12 and t22, respectively, as shown in FIG. The hot / cold ratio at this time is t12: t22 = 1: 2. One cycle t3 at this time is 6 minutes and 30 seconds.
　第３ボタン４５が押されたときの温刺激期間ｔ１と冷刺激期間ｔ２とのそれぞれは、図８に示すように、ｔ１３とｔ２３である。このときの温冷比率は、ｔ１３：ｔ２３＝１：１である。このときの一周期ｔ３は、６分３０秒である。 The warm stimulation period t1 and the cold stimulation period t2 when the third button 45 is pressed are t13 and t23, respectively, as shown in FIG. The hot / cold ratio at this time is t13: t23 = 1: 1. One cycle t3 at this time is 6 minutes and 30 seconds.
　第４ボタン４６が押されたときの温刺激期間ｔ１と冷刺激期間ｔ２とのそれぞれは、図９に示すように、ｔ１４とｔ２４である。このときの温冷比率は、ｔ１４：ｔ２４＝２：１である。このときの一周期ｔ３は、６分３０秒である。 The warm stimulation period t1 and the cold stimulation period t2 when the fourth button 46 is pressed are t14 and t24, respectively, as shown in FIG. The hot / cold ratio at this time is t14: t24 = 2: 1. One cycle t3 at this time is 6 minutes and 30 seconds.
　第５ボタン４７が押されたときの温刺激期間ｔ１と冷刺激期間ｔ２とのそれぞれは、図１０に示すように、ｔ１５とｔ２５である。このときの温冷比率は、ｔ１５：ｔ２５＝３：１である。このときの一周期ｔ３は、６分３０秒である。 The warm stimulation period t1 and the cold stimulation period t2 when the fifth button 47 is pressed are t15 and t25, respectively, as shown in FIG. The hot / cold ratio at this time is t15: t25 = 3: 1. One cycle t3 at this time is 6 minutes and 30 seconds.
　このように、第１ボタン４３、第２ボタン４４、第３ボタン４５、第４ボタン４６、第５ボタン４７の順に、温刺激期間ｔ１が長くなり、冷刺激期間ｔ２が短くなる。各ボタン４３～４７が押されたときの一周期ｔ３の時間は、同じである。 In this way, the warm stimulation period t1 becomes longer and the cold stimulation period t2 becomes shorter in the order of the first button 43, the second button 44, the third button 45, the fourth button 46, and the fifth button 47. The time of one cycle t3 when each button 43 to 47 is pressed is the same.
　図１１に示すように、一周期を同じ時間として、温刺激期間と冷刺激期間との比率を種々の大きさに変更する。図１１中の破線は、一周期の時間が同じであることを示している。この場合、第１ボタン４３、第２ボタン４４を選択したときのように、冷刺激期間の比率が大きいと、温冷刺激を受けている全期間において、着座者は、冷たく感じる。冷刺激期間の比率が大きいほど、着座者が温冷刺激を受けたときに感じる温度が低くなる。 As shown in FIG. 11, the ratio between the warm stimulation period and the cold stimulation period is changed to various sizes with one cycle as the same time. The broken line in FIG. 11 indicates that the time of one cycle is the same. In this case, if the ratio of the cold stimulation period is large, such as when the first button 43 and the second button 44 are selected, the seated person feels cold during the entire period of receiving the hot / cold stimulation. The larger the ratio of the cold stimulation period, the lower the temperature felt by the seated person when receiving the hot / cold stimulation.
　その一方で、第４ボタン４６、第５ボタン４７を選択したときのように、温刺激期間の比率が大きいと、温冷刺激を受けている全期間において、着座者は、温かく感じる。温刺激期間の比率が大きいほど、着座者が温冷刺激を受けたときに感じる温度が高くなる。 On the other hand, if the ratio of the warm stimulation period is large, such as when the 4th button 46 and the 5th button 47 are selected, the seated person feels warm during the entire period of receiving the warm / cold stimulation. The larger the ratio of the warm stimulation period, the higher the temperature felt by the seated person when receiving the warm / cold stimulation.
　そこで、複数の設定ボタン４３～４７には、温冷比率に係る情報として、着座者が温冷刺激を受けたときに感じる温度が示されている。第１ボタン４３には、「低」の文字が示されている。これは、着座者が温冷刺激を受けたときに感じる温度が低いことを意味する。第５ボタン４７には、「高」の文字が示されている。これは、着座者が温冷刺激を受けたときに感じる温度が高いことを意味する。第３ボタン４５には、「中」の文字が示されている。これは、着座者が温冷刺激を受けたときに感じる温度が、「低」のときの温度と「高」のときの温度との中間の温度であることを意味する。第２ボタン４４には、「・」が示されている。これは、着座者が温冷刺激を受けたときに感じる温度が、「低」のときの温度と「中」のときの温度との間の温度であることを示している。第４ボタン４６には、「・」が示されている。これは、着座者が温冷刺激を受けたときに感じる温度が、「中」のときの温度と「高」のときの温度との間の温度を示している。 Therefore, the plurality of setting buttons 43 to 47 indicate the temperature that the seated person feels when receiving the hot / cold stimulus as the information related to the hot / cold ratio. The character "low" is indicated on the first button 43. This means that the temperature felt by the seated person when receiving a hot / cold stimulus is low. The character "high" is indicated on the fifth button 47. This means that the occupant feels a high temperature when receiving a hot / cold stimulus. The character "middle" is indicated on the third button 45. This means that the temperature that the seated person feels when receiving the hot / cold stimulus is an intermediate temperature between the "low" temperature and the "high" temperature. A "." Is indicated on the second button 44. This indicates that the temperature that the seated person feels when receiving the hot / cold stimulus is the temperature between the "low" temperature and the "medium" temperature. A "." Is indicated on the fourth button 46. This indicates that the temperature felt by the seated person when receiving a hot / cold stimulus is between the temperature when the seater is “medium” and the temperature when the seater is “high”.
　第１ボタン４３、第２ボタン４４、第３ボタン４５、第４ボタン４６、第５ボタン４７の順に、着座者が温冷刺激を受けたときに感じる温度が高くなる。複数のボタン４３～４７のいずれか１つを着座者が選択して押すことにより、温冷刺激を受けるときに感じる温度を、着座者が変更することができる。 The temperature felt by the seated person when the seated person receives a hot / cold stimulus increases in the order of the first button 43, the second button 44, the third button 45, the fourth button 46, and the fifth button 47. By selecting and pressing any one of the plurality of buttons 43 to 47, the seated person can change the temperature felt when receiving the hot / cold stimulus.
　このように、各ボタン４３～４７には、温冷比率に係る情報として、着座者が温冷刺激を受けたときに感じる温度が示されている。このため、着座者がこれらのボタン４３～４７のいずれかを選択して押すことで、温冷比率に係る情報が間接的に入力される。よって、本実施形態の設定スイッチ４２が、着座者による操作によって、温冷比率に係る情報を間接的に入力する入力部に相当する。 As described above, each of the buttons 43 to 47 indicates the temperature that the seated person feels when receiving the hot / cold stimulus as the information related to the hot / cold ratio. Therefore, when the seated person selects and presses any of these buttons 43 to 47, the information related to the hot / cold ratio is indirectly input. Therefore, the setting switch 42 of the present embodiment corresponds to an input unit that indirectly inputs information related to the hot / cold ratio by an operation by a seated person.
　制御装置３０は、複数のボタン４３～４７のいずれか１つが押された場合に、押されたボタンに対応する温冷比率で、温刺激期間と冷刺激期間とが交互に繰り返されるように、温冷刺激装置２０を作動させる。これを実現するために、制御装置３０は、図１２に示す処理を実行する。なお、図１２中に示した各ステップは、各種機能を実現する機能部に対応するものである。このことは、他のフローチャートにおいても同様である。 When any one of the plurality of buttons 43 to 47 is pressed, the control device 30 alternately repeats the hot / cold stimulation period and the cold stimulation period at the hot / cold ratio corresponding to the pressed button. The hot / cold stimulator 20 is operated. In order to realize this, the control device 30 executes the process shown in FIG. Each step shown in FIG. 12 corresponds to a functional unit that realizes various functions. This also applies to other flowcharts.
　図１２に示す処理は、作動スイッチ４１がＯＦＦからＯＮに切り替えられたときに開始される。図１２に示す処理は、作動スイッチ４１がＯＮからＯＦＦに切り替えられるまで、繰り返される。なお、図１２に示す処理は、作動スイッチ４１がＯＦＦからＯＮに切り替えられてから所定時間が経過するまで、繰り返されてもよい。 The process shown in FIG. 12 is started when the operation switch 41 is switched from OFF to ON. The process shown in FIG. 12 is repeated until the operation switch 41 is switched from ON to OFF. The process shown in FIG. 12 may be repeated until a predetermined time elapses after the operation switch 41 is switched from OFF to ON.
　ステップＳ１１では、制御装置３０は、設定スイッチ４２のスイッチ信号を読み込む。 In step S11, the control device 30 reads the switch signal of the setting switch 42.
　続いて、ステップＳ１２では、制御装置３０は、ステップＳ１１で読み込んだスイッチ信号に基づいて、温冷比率を決定する。複数のボタン４３～４７のいずれか１つが着座者に押された場合、制御装置３０は、押されたボタンに対応する温冷比率をメモリから読み出す。これにより、今回の温冷比率が決定される。また、作動スイッチ４１がＯＦＦからＯＮに切り替えられてから、複数のボタン４３～４７のいずれも着座者に押されていない場合、標準設定としての第３ボタン４５に対応する温冷比率が、今回の温冷比率として決定される。なお、前回の作動時における作動スイッチ４１がＯＦＦにされる直前の温冷比率が記憶されている場合、その温冷比率が、今回の温冷比率として決定されてもよい。 Subsequently, in step S12, the control device 30 determines the heating / cooling ratio based on the switch signal read in step S11. When any one of the plurality of buttons 43 to 47 is pressed by the seated person, the control device 30 reads the hot / cold ratio corresponding to the pressed button from the memory. This determines the hot / cold ratio this time. Further, when none of the plurality of buttons 43 to 47 is pressed by the seated person after the operation switch 41 is switched from OFF to ON, the heating / cooling ratio corresponding to the third button 45 as a standard setting is set this time. It is determined as the hot / cold ratio of. If the hot / cold ratio immediately before the operation switch 41 is turned off at the time of the previous operation is stored, the hot / cold ratio may be determined as the current hot / cold ratio.
　続いて、ステップＳ１３では、制御装置３０は、ステップＳ１２で決定された温冷比率で、温冷刺激装置２０が温冷刺激を供給するように、制御信号を出力する。これにより、温冷刺激装置２０は、ステップＳ１２で決定された温冷比率で、温刺激期間ｔ１と冷刺激期間ｔ２とを交互に繰り返すように、作動する。 Subsequently, in step S13, the control device 30 outputs a control signal so that the hot / cold stimulus device 20 supplies the hot / cold stimulus at the hot / cold ratio determined in step S12. As a result, the hot / cold stimulator 20 operates so as to alternately repeat the hot / cold stimulus period t1 and the cold stimulus period t2 at the hot / cold ratio determined in step S12.
　図１２に示す処理が繰り返し実行されることで、複数のボタン４３～４７のいずれか１つが押される毎に、温冷比率が変更される。例えば、図１３に示すように、第３ボタン４５が押されたとき、第３ボタン４５に対応する温冷比率および一周期で、温冷刺激装置２０が作動する。このときの温刺激期間ｔ１はｔ１３である。このときの冷刺激期間ｔ２はｔ２３である。その後、第４ボタン４６が押されたとき、第４ボタン４６に対応する温冷比率および一周期で、温冷刺激装置２０が作動する。このときの温刺激期間ｔ１は、ｔ１３よりも長いｔ１４である。このときの冷刺激期間ｔ２は、ｔ２３よりも短いｔ２４である。第４ボタン４６に対応する温冷比率のときの一周期ｔ３は、第３ボタン４５に対応する温冷比率のときの一周期ｔ３と同じ時間である。 By repeatedly executing the process shown in FIG. 12, the hot / cold ratio is changed each time any one of the plurality of buttons 43 to 47 is pressed. For example, as shown in FIG. 13, when the third button 45 is pressed, the heating / cooling stimulator 20 operates at the heating / cooling ratio and one cycle corresponding to the third button 45. The warm stimulation period t1 at this time is t13. The cold stimulation period t2 at this time is t23. After that, when the fourth button 46 is pressed, the heating / cooling stimulator 20 operates at the heating / cooling ratio and one cycle corresponding to the fourth button 46. The warm stimulation period t1 at this time is t14, which is longer than t13. The cold stimulation period t2 at this time is t24, which is shorter than t23. The one cycle t3 at the hot / cold ratio corresponding to the fourth button 46 is the same time as the one cycle t3 at the hot / cold ratio corresponding to the third button 45.
　このように、制御装置３０は、ステップＳ１２で、温冷比率を、図１１に示される互いに異なる温冷比率のいずれか１つに決定する。制御装置３０は、ステップＳ１３で、ステップＳ１２で決定された温冷比率で、温刺激期間と冷刺激期間とが交互に繰り返されるように、温冷刺激装置２０の作動を制御する。本実施形態では、ステップＳ１２が、温冷比率を決定する温冷比率決定部に対応する。ステップＳ１３が、温冷刺激装置の作動を制御する刺激制御部に対応する。 As described above, in step S12, the control device 30 determines the heating / cooling ratio to be one of the different heating / cooling ratios shown in FIG. The control device 30 controls the operation of the hot / cold stimulus device 20 so that the hot / cold stimulus period and the cold stimulus period are alternately repeated at the hot / cold ratio determined in step S12 in step S13. In the present embodiment, step S12 corresponds to a hot / cold ratio determining unit that determines a hot / cold ratio. Step S13 corresponds to a stimulus control unit that controls the operation of the hot / cold stimulus device.
　上述の通り、ステップＳ１２で決定される温冷比率には、第３ボタン４５に対応する温冷比率と、第４ボタン４６に対応する温冷比率とが含まれる。制御装置３０は、ステップＳ１２で、第３ボタン４５に対応する温冷比率のときの一周期ｔ３と、第４ボタン４６に対応する温冷比率のときの一周期ｔ３とが、同じ時間となるように、温冷比率を決定する。なお、このことは、第３ボタン４５と第４ボタン４６とに限られず、複数のボタン４３～４７のうち任意の２つのボタンにおいて、言えることである。複数のボタン４３～４７のそれぞれに対応する温冷比率のうちの２つの温冷比率が、第１比率、第２比率に対応する。 As described above, the hot / cold ratio determined in step S12 includes the hot / cold ratio corresponding to the third button 45 and the hot / cold ratio corresponding to the fourth button 46. In step S12, the control device 30 has the same time for one cycle t3 when the hot / cold ratio corresponds to the third button 45 and one cycle t3 when the hot / cold ratio corresponds to the fourth button 46. As described above, the hot / cold ratio is determined. This is not limited to the third button 45 and the fourth button 46, but can be said for any two of the plurality of buttons 43 to 47. Two of the hot / cold ratios corresponding to each of the plurality of buttons 43 to 47 correspond to the first ratio and the second ratio.
　ここで、本発明者の検討によると、温冷刺激の供給において、特定の温冷比率および特定の一周期とされた特定の設定に対して、温冷比率と一周期との両方を変更すると、変更前の設定と比較して、疲労軽減効果が大きく低下する場合があることが分かった。その一方で、上記の特定の設定に対して、一周期の時間を実質的に同じとして、温冷比率を変更した場合、変更前の設定と比較して、疲労軽減効果が低下しないか、疲労軽減効果が低下しても低下の割合が小さく、一定の疲労軽減効果が得られることが分かった。 Here, according to the study of the present inventor, in the supply of the hot / cold stimulus, both the hot / cold ratio and one cycle are changed for a specific setting of a specific hot / cold ratio and a specific cycle. , It was found that the fatigue reduction effect may be significantly reduced compared to the setting before the change. On the other hand, when the hot / cold ratio is changed with the time of one cycle being substantially the same for the above specific setting, the fatigue reduction effect is not reduced or fatigue is not reduced as compared with the setting before the change. It was found that even if the reduction effect is reduced, the rate of reduction is small and a certain fatigue reduction effect can be obtained.
　このため、本実施形態によれば、温冷比率を異ならせても、一周期の時間を同じとしているので、一定の疲労軽減効果が得られる。よって、一定の疲労軽減効果を得つつ、着座者に与える温冷感を調整することができる。 Therefore, according to the present embodiment, even if the heating / cooling ratio is different, the time of one cycle is the same, so that a certain fatigue reducing effect can be obtained. Therefore, it is possible to adjust the feeling of warmth and coldness given to the seated person while obtaining a certain effect of reducing fatigue.
　なお、本実施形態では、制御装置３０は、ステップＳ１２で、第３ボタン４５に対応する温冷比率のときの一周期ｔ３と、第４ボタン４６に対応する温冷比率のときの一周期ｔ３とが、「同じ時間」となるように、温冷比率を決定する。しかしながら、それぞれの一周期ｔ３の時間は、実質的に同じであればよい。この「実質的に同じ」とは、それぞれの一周期ｔ３の差が、それぞれの一周期の平均値の５％以内であることを意味する。 In the present embodiment, in step S12, the control device 30 has one cycle t3 when the hot / cold ratio corresponds to the third button 45 and one cycle t3 when the hot / cold ratio corresponds to the fourth button 46. Determine the hot / cold ratio so that "and" are "at the same time". However, the time of each cycle t3 may be substantially the same. This "substantially the same" means that the difference in each cycle t3 is within 5% of the average value of each cycle.
　また、本実施形態では、温冷刺激システム１０は、設定スイッチ４２、すなわち、複数の設定ボタン４３～４７を備えている。制御装置３０は、ステップＳ２０で、複数の設定ボタン４３～４７によって入力される情報に基づいて、温冷比率を決定する。これによれば、着座者に与える温冷刺激の温冷感を、着座者の好みの温冷感に調整することができる。 Further, in the present embodiment, the heating / cooling stimulation system 10 includes a setting switch 42, that is, a plurality of setting buttons 43 to 47. In step S20, the control device 30 determines the hot / cold ratio based on the information input by the plurality of setting buttons 43 to 47. According to this, the warm / cold feeling of the hot / cold stimulus given to the seated person can be adjusted to the preferred warm / cold feeling of the seated person.
　（第２実施形態）
　図１４に示すように、本実施形態の温冷刺激システム１０では、第１実施形態の設定スイッチ４２の替わりに、着座者の温冷感を推定するためのセンサ類４８が制御装置３０の入力側に接続されている。また、第１実施形態と異なり、制御装置３０は、図１５に示す処理を行う。温冷刺激システム１０の他の構成は、第１実施形態と同じである。 (Second Embodiment)
As shown in FIG. 14, in the heating / cooling stimulation system 10 of the present embodiment, instead of the setting switch 42 of the first embodiment, sensors 48 for estimating the heating / cooling sensation of the seated person are input to the control device 30. It is connected to the side. Further, unlike the first embodiment, the control device 30 performs the process shown in FIG. The other configuration of the hot / cold stimulation system 10 is the same as that of the first embodiment.
　センサ類４８は、着座者の温冷感に関する物理量を検出する。温冷感は、暑い、寒い等の熱的な感覚である。センサ類４８には、着座者の表面温度を検出するセンサ、シート１０１の表面温度を検出するセンサ、着座者の吸熱時または放熱時の熱流を検出するセンサ、シート１０１の吸熱時または放熱時の熱流を検出するセンサ、車室内の空気温度を検出するセンサ等が含まれる。 Sensors 48 detect physical quantities related to the feeling of warmth and coldness of the seated person. The feeling of warmth and coldness is a thermal sensation such as hot or cold. The sensors 48 include a sensor that detects the surface temperature of the seat, a sensor that detects the surface temperature of the seat 101, a sensor that detects the heat flow during heat absorption or heat dissipation of the seat, and a sensor that detects heat absorption or heat dissipation of the seat 101. It includes a sensor that detects heat flow, a sensor that detects the air temperature inside the vehicle, and the like.
　図１５に示すように、ステップＳ２１で、制御装置３０は、センサ類４８から入力されるセンサ信号を読み込む。 As shown in FIG. 15, in step S21, the control device 30 reads the sensor signal input from the sensors 48.
　続いて、ステップＳ２２で、制御装置３０は、センサ信号に基づいて、着座者の温冷感を推定する。例えば、制御装置３０は、現時点の着座者の温冷感が、「暑い」、「やや暑い」、「中立」、「やや寒い」、「寒い」のいずれに該当するか判定する。 Subsequently, in step S22, the control device 30 estimates the feeling of warmth and coldness of the seated person based on the sensor signal. For example, the control device 30 determines whether the current feeling of warmth or coldness of the seated person corresponds to "hot", "slightly hot", "neutral", "slightly cold", or "cold".
　続いて、ステップＳ２３で、制御装置３０は、ステップＳ２２の推定結果に基づいて、温冷比率を決定する。 Subsequently, in step S23, the control device 30 determines the hot / cold ratio based on the estimation result of step S22.
　具体的には、図１６に示すように、ステップＳ２２での推定結果が「暑い」のときの温冷比率を、冷刺激期間の比率が大きい比率に決定する。例えば、このときの温冷比率および一周期は、第１実施形態の第１ボタン４３のときの温冷比率および一周期と同じである。これにより、着座者に冷たく感じさせることができる。 Specifically, as shown in FIG. 16, the hot / cold ratio when the estimation result in step S22 is "hot" is determined to have a large ratio of the cold stimulation period. For example, the hot / cold ratio and one cycle at this time are the same as the hot / cold ratio and one cycle at the time of the first button 43 of the first embodiment. This makes the seated person feel cold.
　また、ステップＳ２２での推定結果が「やや暑い」のときの温冷比率を、冷刺激期間の比率がやや大きい比率に決定する。例えば、このときの温冷比率および一周期は、第１実施形態の第２ボタン４４のときの温冷比率および一周期と同じである。これにより、着座者にやや冷たく感じさせることができる。 Further, the hot / cold ratio when the estimation result in step S22 is "slightly hot" is determined to be a ratio in which the ratio of the cold stimulation period is slightly large. For example, the hot / cold ratio and one cycle at this time are the same as the hot / cold ratio and one cycle at the time of the second button 44 of the first embodiment. This makes the seated person feel a little cold.
　また、ステップＳ２２での推定結果が「中立」のときの温冷比率を、冷刺激期間と温刺激期間とが同じ長さの比率に決定する。例えば、このときの温冷比率および一周期は、第１実施形態の第３ボタン４５のときの温冷比率および一周期と同じである。 Further, the hot / cold ratio when the estimation result in step S22 is "neutral" is determined so that the cold stimulation period and the warm stimulation period have the same length. For example, the hot / cold ratio and one cycle at this time are the same as the hot / cold ratio and one cycle at the time of the third button 45 of the first embodiment.
　また、ステップＳ２２での推定結果が「やや寒い」のときの温冷比率を、温刺激期間の比率がやや大きい比率に決定する。例えば、このときの温冷比率は、第１実施形態の第４ボタン４６のときの温冷比率と同じである。これにより、着座者にやや温かく感じさせることができる。 Further, the temperature / cold ratio when the estimation result in step S22 is "slightly cold" is determined to be a ratio in which the ratio of the warm stimulation period is slightly large. For example, the hot / cold ratio at this time is the same as the hot / cold ratio at the time of the fourth button 46 of the first embodiment. This makes the seated person feel a little warm.
　また、ステップＳ２２での推定結果が「寒い」のときの温冷比率を、温刺激期間の比率が大きい比率に決定する。例えば、このときの温冷比率は、第１実施形態の第５ボタン４７のときの温冷比率と同じである。これにより、着座者に温かく感じさせることができる。 Further, the hot / cold ratio when the estimation result in step S22 is "cold" is determined to be a ratio in which the ratio of the warm stimulation period is large. For example, the hot / cold ratio at this time is the same as the hot / cold ratio at the time of the fifth button 47 of the first embodiment. This makes the seated person feel warm.
　続いて、ステップＳ２４で、制御装置３０は、ステップＳ２３で決定された温冷比率で、温冷刺激装置２０を作動させるための制御信号を出力する。これにより、温冷刺激装置２０は、ステップＳ１２で決定された温冷比率で、温刺激期間と冷刺激期間とが交互に繰り返されるように、作動する。 Subsequently, in step S24, the control device 30 outputs a control signal for operating the hot / cold stimulator 20 at the hot / cold ratio determined in step S23. As a result, the hot / cold stimulator 20 operates so that the hot / cold stimulus period and the cold stimulus period are alternately repeated at the hot / cold ratio determined in step S12.
　以上の説明の通り、制御装置３０は、ステップＳ２３で、温冷比率を、図１６に示される互いに異なる温冷比率のいずれか１つに決定する。制御装置３０は、ステップＳ２４で、ステップＳ２３で決定された温冷比率で、温刺激期間と冷刺激期間とが交互に繰り返されるように、温冷刺激装置２０の作動を制御する。本実施形態では、ステップＳ２３が、温冷比率を決定する温冷比率決定部に対応する。ステップＳ２４が、温冷刺激装置の作動を制御する刺激制御部に対応する。制御装置３０は、ステップＳ２３で、温冷比率を種々の比率に決定するとき、いずれの比率のときにおいても、一周期の時間が同じとなるように、温冷比率を決定する。このため、本実施形態においても、第１実施形態と同様の効果が得られる。 As described above, in step S23, the control device 30 determines the heating / cooling ratio to be one of the different heating / cooling ratios shown in FIG. The control device 30 controls the operation of the hot / cold stimulus device 20 so that the hot / cold stimulus period and the cold stimulus period are alternately repeated at the hot / cold ratio determined in step S23 in step S24. In the present embodiment, step S23 corresponds to a hot / cold ratio determining unit that determines a hot / cold ratio. Step S24 corresponds to a stimulus control unit that controls the operation of the hot / cold stimulus device. When the control device 30 determines the hot / cold ratio to various ratios in step S23, the control device 30 determines the hot / cold ratio so that the time of one cycle is the same regardless of the ratio. Therefore, the same effect as that of the first embodiment can be obtained in this embodiment as well.
　また、本実施形態では、ステップＳ２２で、制御装置３０は、着座者の温冷感を推定する。そして、ステップＳ２３で、制御装置３０は、ステップＳ２２の推定結果に基づいて、温冷比率を決定する。これにより、着座者に与える温冷刺激の温冷感を着座者の好みの温冷感に調整することができる。例えば、着座者が暑いと感じているときに、冷たく感じる温冷比率に調整することができる。着座者が寒いと感じているときに、温かく感じる温冷比率に調整することができる。なお、本実施形態では、ステップＳ２２が、温冷刺激システムが備える推定部に対応する。 Further, in the present embodiment, in step S22, the control device 30 estimates the feeling of warmth and coldness of the seated person. Then, in step S23, the control device 30 determines the heating / cooling ratio based on the estimation result of step S22. Thereby, the warm / cold feeling of the hot / cold stimulus given to the seated person can be adjusted to the preferred hot / cold feeling of the seated person. For example, it can be adjusted to a hot / cold ratio that makes the seater feel cold when he / she feels hot. It can be adjusted to a warm / cold ratio that makes the seater feel warm when he / she feels cold. In this embodiment, step S22 corresponds to the estimation unit included in the hot / cold stimulation system.
　また、本実施形態では、ステップＳ２２で、制御装置３０は、着座者の温冷感を推定する。しかしながら、ステップＳ２２で、制御装置３０は、着座者の温冷快適感を推定してもよい。温冷快適感は、温冷感と「快適」、「不快」の快適感とを合わせたものである。この場合、センサ類４８は、温冷快適感を推定するための物理量を検出する。 Further, in the present embodiment, in step S22, the control device 30 estimates the feeling of warmth and coldness of the seated person. However, in step S22, the control device 30 may estimate the warm / cold comfort of the seated person. The feeling of warm / cold comfort is a combination of the feeling of warm / cold and the feeling of "comfort" and "discomfort". In this case, the sensors 48 detect a physical quantity for estimating the feeling of warm / cold comfort.
　（第３実施形態）
　図１７に示すように、本実施形態の温冷刺激システム１０では、第１実施形態の設定スイッチ４２の替わりに、空調用制御装置４９および車室内空間の実際の空気温度を測定するセンサ５０が制御装置３０の入力側に接続されている。また、第１実施形態と異なり、制御装置３０は、図１８に示す処理を行う。温冷刺激システム１０の他の構成は、第１実施形態と同じである。 (Third Embodiment)
As shown in FIG. 17, in the heating / cooling stimulation system 10 of the present embodiment, instead of the setting switch 42 of the first embodiment, the air conditioning control device 49 and the sensor 50 for measuring the actual air temperature in the vehicle interior space are used. It is connected to the input side of the control device 30. Further, unlike the first embodiment, the control device 30 performs the process shown in FIG. The other configuration of the hot / cold stimulation system 10 is the same as that of the first embodiment.
　空調用制御装置４９は、図示しない空調装置を制御する。空調装置は、着座者が存在する車室内空間の空気温度を調整する。空調用制御装置４９は、図示しない温度設定部から空調装置の設定温度が入力される。温度設定部は、着座者の操作によって、空調装置の設定温度を入力する入力部である。 The air conditioning control device 49 controls an air conditioning device (not shown). The air conditioner regulates the air temperature in the vehicle interior space where the seated person is present. In the air-conditioning control device 49, the set temperature of the air-conditioning device is input from a temperature setting unit (not shown). The temperature setting unit is an input unit for inputting the set temperature of the air conditioner by the operation of the seated person.
　図１８に示すように、ステップＳ３１で、制御装置３０は、空調用制御装置４９との間の通信によって設定温度を取得するとともに、センサ５０から入力されるセンサ信号を読み込む。 As shown in FIG. 18, in step S31, the control device 30 acquires the set temperature by communication with the air conditioning control device 49, and reads the sensor signal input from the sensor 50.
　続いて、ステップＳ３２で、制御装置３０は、設定温度およびセンサ信号に基づいて、設定温度と、実際に測定された車室内空気の実測温度との温度差を算出する。 Subsequently, in step S32, the control device 30 calculates the temperature difference between the set temperature and the actually measured temperature of the vehicle interior air based on the set temperature and the sensor signal.
　続いて、ステップＳ３３で、制御装置３０は、ステップＳ３２で算出された温度差に基づいて、温冷比率を決定する。 Subsequently, in step S33, the control device 30 determines the temperature / cooling ratio based on the temperature difference calculated in step S32.
　具体的には、図１９に示すように、ステップＳ３２での算出結果が「実測温度の方が高く、差が大きい」ときの温冷比率を、冷刺激期間の比率が大きい比率に決定する。例えば、このときの温冷比率および一周期は、第１実施形態の第１ボタン４３のときの温冷比率および一周期と同じである。これにより、着座者に冷たく感じさせることができる。 Specifically, as shown in FIG. 19, the hot / cold ratio when the calculation result in step S32 is "the measured temperature is higher and the difference is larger" is determined to be the ratio in which the ratio of the cold stimulation period is large. For example, the hot / cold ratio and one cycle at this time are the same as the hot / cold ratio and one cycle at the time of the first button 43 of the first embodiment. This makes the seated person feel cold.
　また、ステップＳ３２での推定結果が「実測温度の方が高く、差がやや大きい」ときの温冷比率を、冷刺激期間の比率がやや大きい比率に決定する。例えば、このときの温冷比率および一周期は、第１実施形態の第２ボタン４４のときの温冷比率および一周期と同じである。これにより、着座者にやや冷たく感じさせることができる。 Further, the temperature / cooling ratio when the estimation result in step S32 is "the measured temperature is higher and the difference is slightly larger" is determined to be a ratio in which the ratio of the cold stimulation period is slightly larger. For example, the hot / cold ratio and one cycle at this time are the same as the hot / cold ratio and one cycle at the time of the second button 44 of the first embodiment. This makes the seated person feel a little cold.
　また、ステップＳ３２での推定結果が「差が小さい」ときの温冷比率を、冷刺激期間と温刺激期間とが同じ長さの比率に決定する。例えば、このときの温冷比率および一周期は、第１実施形態の第３ボタン４５のときの温冷比率および一周期と同じである。 Further, the hot / cold ratio when the estimation result in step S32 is "small difference" is determined so that the cold stimulation period and the warm stimulation period have the same length. For example, the hot / cold ratio and one cycle at this time are the same as the hot / cold ratio and one cycle at the time of the third button 45 of the first embodiment.
　また、ステップＳ３２での推定結果が「実測温度の方が低く、差がやや大きい」ときの温冷比率を、温刺激期間の比率がやや大きい比率に決定する。例えば、このときの温冷比率は、第１実施形態の第４ボタン４６のときの温冷比率と同じである。これにより、着座者にやや温かく感じさせることができる。 Further, the temperature / cooling ratio when the estimation result in step S32 is "the measured temperature is lower and the difference is slightly larger" is determined to be a ratio in which the ratio of the warm stimulation period is slightly larger. For example, the hot / cold ratio at this time is the same as the hot / cold ratio at the time of the fourth button 46 of the first embodiment. This makes the seated person feel a little warm.
　また、ステップＳ３２での推定結果が「実測温度の方が低く、差が大きい」ときの温冷比率を、温刺激期間の比率が大きい比率に決定する。例えば、このときの温冷比率は、第１実施形態の第５ボタン４７のときの温冷比率と同じである。これにより、着座者に温かく感じさせることができる。 Further, the temperature / cooling ratio when the estimation result in step S32 is "the measured temperature is lower and the difference is larger" is determined to be the ratio of the temperature stimulation period. For example, the hot / cold ratio at this time is the same as the hot / cold ratio at the time of the fifth button 47 of the first embodiment. This makes the seated person feel warm.
　続いて、ステップＳ３４で、制御装置３０は、ステップＳ３３で決定された温冷比率で、温冷刺激装置２０を作動させるための制御信号を出力する。これにより、温冷刺激装置２０は、ステップＳ３３で決定された温冷比率で、温刺激期間と冷刺激期間とが交互に繰り返されるように、作動する。 Subsequently, in step S34, the control device 30 outputs a control signal for operating the hot / cold stimulator 20 at the hot / cold ratio determined in step S33. As a result, the hot / cold stimulator 20 operates so that the hot / cold stimulus period and the cold stimulus period are alternately repeated at the hot / cold ratio determined in step S33.
　以上の説明の通り、制御装置３０は、ステップＳ３３で、温冷比率を、図１９に示される互いに異なる温冷比率のいずれか１つに決定する。制御装置３０は、ステップＳ３４で、ステップＳ３３で決定された温冷比率で、温刺激期間と冷刺激期間とが交互に繰り返されるように、温冷刺激装置２０の作動を制御する。本実施形態では、ステップＳ３３が、温冷比率を決定する温冷比率決定部に対応する。ステップＳ３４が、温冷刺激装置の作動を制御する刺激制御部に対応する。制御装置３０は、ステップＳ３３で、温冷比率を種々の比率に決定するとき、いずれの比率のときにおいても、一周期の時間が同じとなるように、温冷比率を決定する。このため、本実施形態においても、第１実施形態と同様の効果が得られる。 As described above, in step S33, the control device 30 determines the heating / cooling ratio to be one of the different heating / cooling ratios shown in FIG. The control device 30 controls the operation of the hot / cold stimulus device 20 so that the hot / cold stimulus period and the cold stimulus period are alternately repeated at the hot / cold ratio determined in step S33 in step S34. In the present embodiment, step S33 corresponds to a hot / cold ratio determining unit that determines the hot / cold ratio. Step S34 corresponds to a stimulus control unit that controls the operation of the hot / cold stimulus device. When the control device 30 determines the hot / cold ratio to various ratios in step S33, the control device 30 determines the hot / cold ratio so that the time of one cycle is the same regardless of the ratio. Therefore, the same effect as that of the first embodiment can be obtained in this embodiment as well.
　また、本実施形態では、ステップＳ３３で、制御装置３０は、空調装置の設定温度と車室内空気の実測温度との温度差に基づいて、温冷比率を決定する。これにより、着座者に与える温冷刺激の温冷感を着座者の好みの温冷感に調整することができる。例えば、実測温度の方が設定温度よりも高いときに、冷たく感じる温冷比率に調整することができる。実測温度の方が設定温度よりも低いときに、温かく感じる温冷比率に調整することができる。 Further, in the present embodiment, in step S33, the control device 30 determines the temperature / cooling ratio based on the temperature difference between the set temperature of the air conditioner and the measured temperature of the vehicle interior air. Thereby, the warm / cold feeling of the hot / cold stimulus given to the seated person can be adjusted to the preferred hot / cold feeling of the seated person. For example, when the measured temperature is higher than the set temperature, the temperature can be adjusted to feel cold. When the measured temperature is lower than the set temperature, the temperature can be adjusted to feel warm.
　なお、本実施形態では、制御装置３０は、設定温度と実測温度との算出結果に基づいて、温冷比率を決定する。すなわち、制御装置３０は、設定温度と実測温度とに基づいて温冷比率を決定する。しかしながら、制御装置３０は、設定温度と実測温度との温度差を算出せずに、設定温度と実測温度とに基づいて、温冷比率を決定してもよい。 In the present embodiment, the control device 30 determines the hot / cold ratio based on the calculation results of the set temperature and the measured temperature. That is, the control device 30 determines the hot / cold ratio based on the set temperature and the measured temperature. However, the control device 30 may determine the temperature / cooling ratio based on the set temperature and the measured temperature without calculating the temperature difference between the set temperature and the measured temperature.
　また、本実施形態では、制御装置３０は、空調用制御装置４９から設定温度を取得する。しかしながら、制御装置３０が空調用制御装置を兼ねる場合、温度設定部からの設定信号に基づいて設定温度を取得してもよい。 Further, in the present embodiment, the control device 30 acquires the set temperature from the air conditioning control device 49. However, when the control device 30 also serves as an air conditioning control device, the set temperature may be acquired based on the set signal from the temperature setting unit.

It may be composed of. In this case, when the seated person presses the button displayed with "+", the ratio of the warm stimulation period becomes large. When the seated person presses the button displayed with "-", the ratio of the cold stimulation period increases. In this way, when the seated person selects and presses one of the two setting buttons, the information related to the hot / cold ratio is indirectly input. Therefore, these two setting buttons also correspond to input units that indirectly input information related to the hot / cold ratio by the operation by the seated person.
　また、設定スイッチ４２は、複数の温冷比率が表示された複数の設定ボタンで構成されてもよい。この場合、着座者がこれらの設定ボタンのいずれか１つを押すことで、温冷比率に係る情報が直接的に入力される。よって、これらの設定ボタンは、着座者による操作によって、温冷比率に係る情報を直接的に入力する入力部に相当する。 Further, the setting switch 42 may be composed of a plurality of setting buttons displaying a plurality of hot / cold ratios.
