Description
本発明は温度制御装置に関し、特にバッテリと左右にグリップ部分が一対存しているステアリングハンドルとを備えた乗り物において、前記グリップ部分の温度を制御する温度制御装置に関するものである。
The present invention relates to a temperature control device, and more particularly to a temperature control device that controls the temperature of the grip portion in a vehicle including a battery and a steering handle having a pair of grip portions on the left and right sides.
二輪車（自動二輪車、自転車及び原動機付き自転車等）、スノーモービル、水上バイク及び三輪バギー等の車両のステアリングハンドルは左右にそれぞれ一つずつ設けられている。このようなハンドルにおいて左右のハンドルグリップの内部にニクロム線又は銅箔又は、ＳＵＳ箔などを所定のパターンに形成したヒータを設け、電源部からヒータへ通電することによりハンドルグリップを加温し、冬季又は寒冷地において運転者が快適に運転することのできるグリップヒータ装置が従来より開発されて実際にステアリングハンドルに適用されている。
Steering handles for vehicles such as motorcycles (motorcycles, bicycles, motorbikes, etc.), snowmobiles, water bikes, and three-wheel buggies are provided on the left and right respectively. In such a handle, a heater in which a nichrome wire, copper foil, SUS foil or the like is formed in a predetermined pattern is provided inside the left and right handle grips, and the handle grips are heated by energizing the heater from the power supply unit. Or the grip heater apparatus which a driver | operator can drive comfortably in a cold region was developed conventionally, and is actually applied to the steering wheel.
二輪車等の車両では自動車に比べてハンドル近辺のスイッチ類やメータ類を多くすることが難しく、またスイッチ操作等も簡単に行えるようにしなければ安全な運転に支障をきたしてしまう。そのため、グリップヒータの通電量を容易に制御できる制御装置（例えば、特許文献１）が必要となる。
In vehicles such as motorcycles, it is difficult to increase the number of switches and meters near the steering wheel as compared to automobiles, and safe operation will be hindered unless the switches can be easily operated. Therefore, a control device (for example, Patent Document 1) that can easily control the energization amount of the grip heater is required.
従来のグリップヒータの制御装置（例えば、特許文献１，２，３）ではヒータの加熱レベルをスイッチ操作で決定するとそれに応じたデューティ比を設定して左右のグリップを同じように加熱するというＰＷＭ（Ｐulse Ｗidth Ｍodulation）方式の制御を行うだけであった。しかしながら、左右のグリップは機能（アクセル、ブレーキ、クラッチなど）が異なっているので構造も異なっており、そのため左側と右側とではグリップ全体における熱伝導の形態が異なって左右でグリップに温度差が生じてしまうという問題があった。
In a conventional grip heater control device (for example, Patent Documents 1, 2, and 3), when the heating level of the heater is determined by a switch operation, a duty ratio is set accordingly and the left and right grips are heated in the same manner (PWM). It only performed control of the Pulse Width Modulation) method. However, since the left and right grips have different functions (accelerator, brake, clutch, etc.), the structure is also different. Therefore, the heat conduction form of the entire grip is different between the left and right sides, resulting in a temperature difference between the left and right grips. There was a problem that.
本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、左右のグリップの温度が同じになるように制御する温度制御装置を提供することにある。
The present invention has been made in view of this point, and an object of the present invention is to provide a temperature control device for controlling the left and right grips to have the same temperature.
本発明の温度制御装置は、バッテリと左右にグリップ部分が一対存しているステアリングハンドルとを備えた乗り物において、前記グリップ部分の温度を制御する温度制御装置であって、一対の前記グリップ部分に設置された左右一対のヒータと、一対の前記グリップ部分に設置された左右一対の温度センサと、前記グリップ部分の温度を所定温度とするために、前記所定温度が設定される温度設定部と、前記ヒータへ供給される電力量を制御する制御部とを備え、前記制御部は、前記温度センサからの測定信号及び前記所定温度とを用いて、左右の前記グリップ部分の温度を同じにするように制御を行う構成を有している。
The temperature control device according to the present invention is a temperature control device for controlling the temperature of the grip portion in a vehicle including a battery and a steering handle having a pair of grip portions on the left and right sides.

It has the structure which controls.
前記制御部は、前記温度設定部において前記所定温度が設定されてから、前記グリップ部分の温度が前記所定温度に近づいて電力量を減少させる制御を開始するまでの間前記ヒータへ供給する立ち上がり電力を、前記所定温度の大きさによらず同じ電力とすることが好ましい。
The control unit supplies rising power to the heater from when the predetermined temperature is set by the temperature setting unit until the temperature of the grip portion approaches the predetermined temperature and control for reducing the amount of electric power is started. Are preferably set to the same power regardless of the predetermined temperature.
前記制御部は、前記バッテリの電圧を検出する電圧監視部を備えており、前記バッテリの電圧が所定閾値以下である時は前記ヒータへの電力量を０にすることが好ましい。
It is preferable that the control unit includes a voltage monitoring unit that detects the voltage of the battery, and when the battery voltage is equal to or lower than a predetermined threshold, the electric energy to the heater is set to zero.
本発明の温度制御装置は左右のグリップ部分にそれぞれ温度センサを備えて、それらからの測定信号を用いて温度制御を行っているので、左右のグリップの温度が同じになるように制御を行うことができる。
Since the temperature control device of the present invention is provided with temperature sensors in the left and right grip portions and performs temperature control using measurement signals from them, control is performed so that the temperatures of the left and right grips are the same. Can do.
実施形態について説明をする前に、本発明に至った経緯について説明を行う。
Before describing the embodiment, the background to the present invention will be described.
二輪車（自動二輪車、自転車及び原動機付き自転車等）、スノーモービル、水上バイク及び三輪バギー等のバッテリを備えた車両の左右のグリップ部分を加熱する際、図１（ａ）に示すように、従来のヒータ部分の加熱制御では温度センサが無く単に供給電力量を制御するだけであるので、左右のグリップの構造の違いなどに起因して、右側のグリップ部分の温度Ｒと左側のグリップ部分の温度Ｌとが同じにはならない。
When heating left and right grip parts of a vehicle equipped with a battery such as a motorcycle (motorcycle, bicycle, motorbike, etc.), snowmobile, water bike, and three-wheel buggy, as shown in FIG. In the heating control of the heater part, there is no temperature sensor, and the power supply amount is merely controlled. Therefore, due to the difference in the structure of the left and right grips, the temperature R of the right grip part and the temperature L of the left grip part And will not be the same.
また、特許文献１における二輪車、スノーモービル、水上バイク及び三輪バギー、船外機等のステアリングハンドルに設けられるグリップヒータの制御装置においては、図１０に示すようにＰＷＭ方式の加熱制御を行っている。図１０では、ヒータの加熱レベルが高い方から低い方へ順にＬＶ３、ＬＶ２、ＬＶ１と３つ有る場合が示されている。ＬＶ１～３において、ヒータへの通電電圧はいずれのレベルでも同じ大きさであるが、通電時間をデューティ比によって変えている。すなわち、ＬＶ３ではデューティ比が１００％であって常に通電しているのに対し、ＬＶ２ではデューティ比が７５％であって、通電のＯＮ／ＯＦＦが７５対２５の時間割合で交互に繰り返される。ＬＶ１ではデューティ比が５０％であるので、通電のＯＮ／ＯＦＦが５０対５０の時間割合で交互に繰り返される。
Further, in the control device for the grip heater provided in the steering handle of a motorcycle, snowmobile, water bike, three-wheel buggy, outboard motor, etc. in Patent Document 1, PWM-type heating control is performed as shown in FIG. . FIG. 10 shows a case where there are three LV3, LV2, and LV1 in order from the higher heating level of the heater to the lower heating level. In LV1 to LV3, the energization voltage to the heater is the same at any level, but the energization time is changed depending on the duty ratio. In other words, LV3 has a duty ratio of 100% and is always energized, whereas LV2 has a duty ratio of 75%, and ON / OFF of energization is alternately repeated at a time ratio of 75:25. In LV1, since the duty ratio is 50%, ON / OFF of energization is repeated alternately at a time ratio of 50:50.
このようにデューティ比を変えることによって目標とする温度レベルを変えている。しかし、図２（ａ）に示すようにデューティ比が小さいと、立ち上がり時の温度勾配が小さくなってしまう。このためデューティ比が小さい（設定温度レベルが低い）と目標とする温度にまでグリップ部分が暖められるのに時間がかかり、その間に使用者は寒さを我慢しなければならない。
The target temperature level is changed by changing the duty ratio in this way. However, if the duty ratio is small as shown in FIG. 2 (a), the temperature gradient at the time of rising becomes small. For this reason, when the duty ratio is small (the set temperature level is low), it takes time for the grip portion to be warmed to the target temperature, and the user must endure the cold during that time.
また、図３（ａ）に示すように、クラッチやブレーキの操作が比較的多い一般道を走行する場合と、それらの操作が比較的少ない例えば高速道路を走行する場合とを比較すると、ＰＷＭ方式の加熱制御ではそれらの操作が多い方がグリップ部分の温度が低くなってしまう。これは、クラッチやブレーキを操作する際にはグリップを握り込んでいる指の部分がグリップから離れてグリップ部分が外気に触れて冷やされるからである。
Further, as shown in FIG. 3 (a), a comparison between the case where the vehicle travels on a general road with relatively many clutch and brake operations and the case where the operation is relatively light, for example, on a highway, In this heating control, the temperature of the grip portion decreases as the number of operations increases. This is because when the clutch or brake is operated, the part of the finger gripping the grip is separated from the grip and the grip part is touched by the outside air to be cooled.
さらに、図４（ａ）に示すように、ＰＷＭ方式の温度制御では外気温が変化するとそれに伴ってグリップ部分の温度も変化する。これは、外気温が変化するとグリップからの放熱量が変化するのに対して、ヒータ発熱量は外気温変化によらず一定であるためである。
Furthermore, as shown in FIG. 4A, in the temperature control of the PWM system, when the outside air temperature changes, the temperature of the grip portion also changes accordingly. This is because the amount of heat released from the grip changes when the outside air temperature changes, whereas the heater heat generation amount is constant regardless of the outside air temperature change.
これまで述べたように、特許文献１における加熱制御装置では加熱設定をあるレベル（例えばＬＶ２）に固定していても、様々な要因でグリップ部分の温度が変動してしまうとともに、立ち上がりの温度勾配が低く、左右に温度差も生じてしまう。特許文献１における加熱制御装置では左右の温度差をなくすことはできないが、それ以外の温度変動や立ち上がり時の温度勾配の低さは、図１１に示すような運転者による加熱設定レベルの操作によってある程度は修正することが可能である。
As described above, even if the heating setting is fixed at a certain level (for example, LV2) in the heating control device in Patent Document 1, the temperature of the grip portion varies due to various factors, and the rising temperature gradient. And the temperature difference between the left and right is also generated. The heating control device in Patent Document 1 cannot eliminate the temperature difference between the left and right sides, but other temperature fluctuations and low temperature gradients at the time of rising can be achieved by operating the heating setting level as shown in FIG. It can be corrected to some extent.
図１１においては、運転者はＬＶ２という加熱設定が快適なグリップ温度になると判断している。しかし運転開始からｔ１までは、温度上昇勾配を大きくして早くグリップを暖めるため、運転者は加熱設定をＬＶ３に設定している。ＬＶ２ではＡに示すようにグリップ温度上昇の立ち上がりが遅くなる。
In FIG. 11, the driver determines that the heating setting of LV2 is a comfortable grip temperature. However, from the start of operation to t1, in order to warm the grip quickly by increasing the temperature rise gradient, the driver sets the heating setting to LV3. In LV2, as shown by A, the rise of the grip temperature rises slowly.
図１１に示すように、ｔ１の時点で温度が高くなりすぎるので運転者はＬＶ２に設定する。ｔ１からｔ２の間、ブレーキやクラッチ操作が多く速度変動も大きい街中走行をしているので、ＬＶ２の設定でグリップ部分は所定温度となっている。
As shown in FIG. 11, since the temperature becomes too high at the time t1, the driver sets it to LV2. Between t1 and t2, the vehicle is traveling in the city where there are many brakes and clutch operations and large speed fluctuations. Therefore, the grip portion is at a predetermined temperature by setting LV2.
次にｔ２からｔ３まで、グリップから手を離す頻度が低い高速道路走行を行うと、ＬＶ２の設定ではだんだんとグリップ部分の温度が上昇していくので、Ｂの時点で運転者は温度設定をＬＶ１に切り替えている。再びｔ３から、グリップから手を離す頻度が高い街中走行になると、グリップ温度が低下してくるので、Ｃの時点で運転者は再び加熱設定をＬＶ２に変更して、グリップ部分の温度を調節している。しかしこのような手動調整は運転者の熟練度合いによって巧拙の差が現れる。また、この方法では温度を一定に保つことは非常に困難であるとともに、そもそも特定レベルの加熱設定が特定のグリップ部分の温度に直結しないため、加熱設定を数段階に設定している意味がなくなってしまう。
Next, from t2 to t3, when driving on an expressway where the frequency of releasing hands from the grip is low, the temperature of the grip portion gradually increases with the setting of LV2, so at time B, the driver changes the temperature setting to LV1. It has been switched to. From t3, when driving in the city where the frequency of releasing the grip is high again, the grip temperature decreases. At time C, the driver changes the heating setting to LV2 again and adjusts the temperature of the grip portion. ing. However, such manual adjustment shows a skillful difference depending on the skill level of the driver. Also, with this method, it is very difficult to keep the temperature constant, and since the heating setting at a specific level does not directly affect the temperature of a specific grip part, it makes no sense to set the heating setting in several stages. End up.
以上述べたように、自動二輪車のような外気にさらされた左右のグリップ部分が一定の温度になるように制御するには上記のような様々な課題があるが、従来はこれらの課題について言及されておらず具体的な対策も立てられていなかった。また従来のグリップ部分の加熱制御は温度を制御するのではなくヒータへの通電量を制御するだけであったので、当然のようにグリップ部分の温度が一定にはならなかった。そこで、本願発明者らは、左右のグリップ部分の温度を同じできるとともに、自動でグリップ部分の温度を一定に保つことが可能となるように種々の検討を行った結果、本願発明に想到するに至った。
As described above, there are various problems as described above for controlling the left and right grip parts exposed to the outside air such as motorcycles to a constant temperature. Conventionally, these problems have been mentioned. No specific measures were taken. Further, since the conventional heating control of the grip portion only controls the amount of current supplied to the heater, not the temperature, the temperature of the grip portion has not become constant as a matter of course. Accordingly, the inventors of the present application have made various studies so that the temperature of the left and right grip portions can be made the same, and the temperature of the grip portion can be kept constant automatically. It came.

The temperature control apparatus according to the present embodiment includes a controller 40, a temperature setting unit 20, and a heater 63 and a temperature sensor 62 installed in the left and right grip portions 11 and 12, respectively. In the left and right grip portions 11 and 12, a heater 63 and a temperature sensor 62 are disposed on an inner core 64 made of resin, and a cover 61 made of rubber covers the whole.
コントローラ４０には、ヒータ６３へ供給される電力量を制御する制御部が内蔵されている。コントローラ４０はバッテリ５０、温度センサ６２、ヒータ６３及び温度設定部２０と接続されており、バッテリ５０の電力を用いてグリップ部分１１，１２の温度を所定の温度になるように制御する。
The controller 40 has a built-in control unit that controls the amount of power supplied to the heater 63. The controller 40 is connected to the battery 50, the temperature sensor 62, the heater 63, and the temperature setting unit 20, and controls the temperature of the grip portions 11 and 12 to be a predetermined temperature using the power of the battery 50.
ヒータ６３は、例えば、ＳＵＳ（ステンレス鋼）箔を特定の配線パターンに打ち抜いて形成されるもので、インナーコア６４の外面全周または半周に張り付けられる。
The heater 63 is formed, for example, by punching SUS (stainless steel) foil into a specific wiring pattern, and is attached to the entire outer circumference or half circumference of the inner core 64.
温度設定部２０はスイッチを備えており、運転者がスイッチ操作を行うことでグリップ部分１１，１２の温度を所定温度にするように設定を行う。設定した所定温度は、設定温度レベル（例えば、ＬＶ１～ＬＶ３）として温度設定部２０に隣接したインジケータ３０に表示される。
The temperature setting unit 20 includes a switch, and the driver performs a switch operation so that the temperature of the grip portions 11 and 12 is set to a predetermined temperature. The set predetermined temperature is displayed on the indicator 30 adjacent to the temperature setting unit 20 as a set temperature level (for example, LV1 to LV3).
本実施形態の温度制御方法は図７に示すメインルーチンで行われる。
The temperature control method of this embodiment is performed by the main routine shown in FIG.
ステップＳ１において、メイン周期フラグＦｍａｉｎの値を調べ、Ｆｍａｉｎ＝１であるときにはステップＳ２へ移り、Ｆｍａｉｎ＝０であるときにはＦｍａｉｎ＝１となるまで待機する。このメイン周期フラグＦｍａｉｎは１０ｍｓｅｃ毎に「１」となるようにタイマルーチンで制御されている。
In step S1, the value of the main period flag Fmain is checked. When Fmain = 1, the process proceeds to step S2, and when Fmain = 0, the process waits until Fmain = 1. The main cycle flag Fmain is controlled by a timer routine so as to become “1” every 10 msec.
ステップＳ２において、スイッチ入力処理のサブルーチン（温度設定ステップ）が実行される。
In step S2, a switch input processing subroutine (temperature setting step) is executed.
ステップＳ３において、温度検出処理（Ｒ：右側）のサブルーチンが実行される。このサブルーチンは図８に示すものであり、後で説明を行う。
In step S3, a subroutine of temperature detection processing (R: right side) is executed. This subroutine is shown in FIG. 8 and will be described later.
ステップＳ４において、右側のヒータへの出力制御（右側の加熱ステップと調整ステップ）のサブルーチンが実行される。
In step S4, a subroutine for output control to the right heater (right heating step and adjustment step) is executed.
ステップＳ５において、温度検出処理（Ｌ：左側）のサブルーチンが実行される。このサブルーチンは図８に示すものである。
In step S5, a subroutine of temperature detection processing (L: left side) is executed. This subroutine is shown in FIG.
ステップＳ６において、左側のヒータへの出力制御（左側の加熱ステップと調整ステップ）のサブルーチンが実行される。
In step S6, a subroutine for output control (left heating step and adjustment step) to the left heater is executed.
ステップＳ７において、インジケータ出力制御のサブルーチンが実行される。
In step S7, an indicator output control subroutine is executed.
ステップＳ８において、周期フラグＦｍａｉｎをＦｍａｉｎ←０としてリセットしステップＳ１へ戻る。
In step S8, the cycle flag Fmain is reset as Fmain ← 0, and the process returns to step S1.
このようにして、メインルーチンではイグニッションスイッチがオンとなった後に、周期フラグＦｍａｉｎの値を参照しながら１０ｍｓｅｃ毎にステップＳ２～Ｓ７の各サブルーチン処理を実行する。
In this way, in the main routine, after the ignition switch is turned on, the subroutine processes of steps S2 to S7 are executed every 10 msec while referring to the value of the cycle flag Fmain.
スイッチ入力処理のサブルーチンでは、運転者が温度設定部２０によって設定した所定温度を読み込む。
In the switch input processing subroutine, a predetermined temperature set by the driver using the temperature setting unit 20 is read.
次に、ステップＳ３及びＳ５の温度検出処理のサブルーチンについて説明する。温度検出処理のサブルーチンは図８に示すように左側と右側のどちらも同じ処理を行う。
Next, the subroutine of the temperature detection process in steps S3 and S5 will be described. As shown in FIG. 8, the subroutine of the temperature detection process performs the same process on both the left side and the right side.
まずステップＳ２１において、温度センサ６２から温度の測定信号（温度値）を読み込む。
First, in step S21, a temperature measurement signal (temperature value) is read from the temperature sensor 62.
ステップＳ２２において、最古の温度値のデータをバッファから破棄する。なお、温度値のデータは８つのバッファに計時順に格納するようになっている。
In step S22, the oldest temperature value data is discarded from the buffer. The temperature value data is stored in the eight buffers in order of time.
ステップＳ２３において、Ｓ２１において読み込んだ今回の温度値をバッファに格納する。
In step S23, the current temperature value read in S21 is stored in the buffer.
ステップＳ２４において、８つのバッファに格納されたの温度値から温度の移動平均値Ｔａｖｅを算出する。そして今回の温度検出処理のサブルーチンを終了する。
In step S24, the moving average value Tave of the temperature is calculated from the temperature values stored in the eight buffers. Then, the current temperature detection subroutine is completed.
ヒータへの出力制御では、スイッチ入力処理において読み込まれた所定温度と温度の移動平均値Ｔａｖｅとを比較して、所定温度がＴａｖｅより小さければヒータへ通電して電力を供給する。この電力の供給においては、供給される電力量をＯＮ／ＯＦＦ制御や比例制御、ＰＩＤ制御などによって制御を行い、グリップ部分の温度と所定温度とが同じになるように制御する。
In the output control to the heater, the predetermined temperature read in the switch input process is compared with the moving average value Tave of the temperature, and if the predetermined temperature is lower than Tave, the heater is energized to supply power. In this power supply, the amount of power supplied is controlled by ON / OFF control, proportional control, PID control, or the like, so that the temperature of the grip portion is equal to the predetermined temperature.
このように温度の移動平均値Ｔａｖｅを算出してヒータへの出力制御に用いることにより、安定した出力制御を行うことができる。
Thus, stable output control can be performed by calculating the moving average value Tave of the temperature and using it for output control to the heater.
インジケータ出力制御では、設定された所定温度に従ってインジケータ３０に設定温度レベルを表示する。
In the indicator output control, the set temperature level is displayed on the indicator 30 according to the set predetermined temperature.
本実施形態の温度制御装置及び温度制御方法では、左右に一対存している温度センサ６２を利用して左右のグリップ部分１１，１２の温度を測定しながら温度制御を行うため、図１（ｂ）に示すように左右のグリップ部分１１，１２の温度が同じになるように加熱が行われ、運転者を快適にさせることができる。
In the temperature control device and the temperature control method of the present embodiment, the temperature control is performed while measuring the temperature of the left and right grip portions 11 and 12 using the temperature sensors 62 that exist on the left and right sides. ), The left and right grip portions 11 and 12 are heated so as to have the same temperature, and the driver can be made comfortable.
また、ヒータへの出力制御において、所定温度が大きくても小さくても立ち上がり時（所定温度設定から電力供給を制御して温度上昇勾配を抑制し始めるまで）には同じ電力（立ち上がり電力）をヒータへ供給するので、図２（ｂ）に示すように所定温度の大小にかかわらず立ち上がりの温度上昇勾配が一定であり、所定温度が小さいときも素早くグリップ部分が暖まるので、運転者が手を寒く感じる時間を短くすることができる。なお、所定温度に設定して通電を開始したときのヒータへ供給される電力をＳとすると、グリップ部分の温度が所定温度に近づくと温度制御が行われることによってＳよりも小さい電力となる。この電力Ｓが立ち上がり電力である。
In the output control to the heater, the same power (rising power) is applied to the heater at the time of start-up (until the power supply is controlled from the predetermined temperature setting and the temperature rise gradient starts to be suppressed) regardless of whether the predetermined temperature is large or small. As shown in FIG. 2B, the rising temperature rise gradient is constant regardless of the predetermined temperature, and the grip portion is quickly warmed even when the predetermined temperature is small. The feeling time can be shortened. If the power supplied to the heater when energization is started at a predetermined temperature is S, the power is smaller than S by temperature control when the temperature of the grip portion approaches the predetermined temperature. This power S is the rising power.
本実施形態ではヒータへの出力制御において、Ｔａｖｅを用いて温度制御を行っているので、図３（ｂ）に示すように、クラッチやブレーキ操作が多い一般道においてグリップ部分から手が離れて放熱量が増える場合と、クラッチやブレーキ操作が少ない高速道路等においてグリップ部分からの放熱量が少ない場合とで同じ温度になるように制御を行うことができ、運転者が２つの場合で所定温度の設定を変更する必要がない。
In this embodiment, temperature control is performed using Tave in the output control to the heater. Therefore, as shown in FIG. 3B, the hand is released from the grip portion on a general road with many clutch and brake operations. Control can be performed so that the same temperature is obtained when the amount of heat increases and when the amount of heat released from the grip part is small on an expressway or the like where there is little clutch or brake operation. There is no need to change the settings.
同様に、外気温が変化して放熱量が変化しても、本実施形態では図４（ｂ）に示すようにグリップ部分の温度は一定に保たれる。
Similarly, even if the outside air temperature changes and the heat radiation amount changes, in this embodiment, the temperature of the grip portion is kept constant as shown in FIG. 4B.
従って図９に示すように、本実施形態の温度制御装置及び温度制御方法を用いれば、図１１に示すものと同じ環境の変化が生じても、温度設定を変更することなくグリップ部分の温度を一定に保つことができるとともに、左右のグリップ部分の温度を同じに保つことができる。
Therefore, as shown in FIG. 9, if the temperature control device and the temperature control method of this embodiment are used, even if the same environmental change as shown in FIG. 11 occurs, the temperature of the grip portion can be adjusted without changing the temperature setting. It can be kept constant, and the temperature of the left and right grip portions can be kept the same.

出力制御を行うのに先立って、バッテリの電圧が所定の電圧以上であることを確認して所定の電圧以上の場合のみヒータへ通電するステップを行ってもよい。例えば特許文献１の００７４段落から００９０段落に記載されているステップである。これにより、グリップを加熱することによって車両の運転に支障をきたすほどにバッテリ電圧が降下してしまうことを防ぐことができる。
Prior to performing the output control, it is possible to confirm that the battery voltage is equal to or higher than a predetermined voltage, and to energize the heater only when the voltage is higher than the predetermined voltage. For example, the steps are described in paragraphs 0074 to 0090 of Patent Document 1. Thereby, it is possible to prevent the battery voltage from dropping to such an extent that the vehicle operation is hindered by heating the grip.
また、従来は右のグリップ部材のヒータ配線パターンと、左のグリップ部材のヒータ配線パターンを異なるパターンとして左右が同じ温度となるように工夫していたが、温度センサを設けることでヒータ配線が１つのパターン（左右兼用、左右が同じ配線パターン）によって対応することが可能となり、配線パターンを作成する型費用を半分とすることができる。
Conventionally, the heater wiring pattern of the right grip member and the heater wiring pattern of the left grip member have been devised so that the left and right have the same temperature. However, by providing a temperature sensor, the heater wiring is 1 It is possible to cope with two patterns (for both left and right, the same wiring pattern on the left and right), and the mold cost for creating the wiring pattern can be halved.
また、高速道路での運転や街中での運転というような場合に、それぞれの状況に応じて温度制御方法をアレンジしても構わない。例えば、所定時間以内でのブレーキの使用回数、速度、温度センサからの温度情報を検知して、高速道路での運転か、街中での運転かを判断して制御することが可能となる。
Also, in the case of driving on a highway or driving in a city, the temperature control method may be arranged according to each situation. For example, it is possible to detect the number of times the brake is used within a predetermined time, speed, and temperature information from a temperature sensor, and to determine and control whether driving on a highway or driving in a city.
上述の左右にグリップ部分が一対存しているステアリングハンドルの温度制御方法は、一対の前記グリップ部分には、それぞれヒータ及び温度センサが設置されており、前記ステアリングハンドルの前記グリップ部分の温度を所定の温度に設定する温度設定ステップと、前記ヒータに通電し、前記所定の温度を目指して前記ステアリングハンドルを加熱する加熱ステップと、左右一対の前記温度センサから計測されたそれぞれの温度が前記所定の温度となるように左右一対の前記ヒータへの通電をそれぞれ調整する調整ステップとを含むものであってもよい。前記加熱ステップでは、前記所定の温度の大小にかかわらず、前記ヒータへの通電電圧を同じにすることが好ましい。前記加熱ステップと前記調整ステップとを同時に行ってもよい。
The temperature control method for the steering handle having a pair of grip portions on the left and right sides described above is such that a heater and a temperature sensor are installed in each of the pair of grip portions, and the temperature of the grip portion of the steering handle is predetermined. A temperature setting step for setting the temperature to a predetermined temperature; a heating step for energizing the heater to heat the steering handle toward the predetermined temperature; and a temperature measured from the pair of left and right temperature sensors for the predetermined temperature. And an adjustment step for adjusting the energization of the pair of left and right heaters so as to reach the temperature. In the heating step, it is preferable that the energization voltage to the heater is the same regardless of the predetermined temperature. The heating step and the adjusting step may be performed simultaneously.
以上説明したように、本発明に係る温度制御方法は、左右のグリップ部分の温度が同じになるように制御できるので、二輪自動車等のグリップ部分の温度制御方法等として有用である。
As described above, the temperature control method according to the present invention can be controlled so that the left and right grip portions have the same temperature, and thus is useful as a temperature control method for grip portions of motorcycles and the like.
