Description

【０００１】
【発明の属する技術分野】
本発明は、車室内の空調状態を制御特性に基づいて自動制御する車両用空調装置に関する。
【０００２】
【従来の技術】
従来、この種の車両用空調装置は、１つの制御特性が予め決められており、その制御特性に基づいて空調制御用機器の作動を自動制御して、吹出温度、送風量、吸込モード、吹出モード等を自動制御するようになっている。
【０００３】
また、他の従来の空調装置として特開平４−１３１６４１号公報に記載されたものがある。この従来装置は、空調対象者が行った空調操作情報を各空調対象者毎に記憶し、画像情報から空調対象者の認識を行い、認識した空調対象者が過去に行った空調操作情報に基づいて空調制御を行うことにより、各空調対象者の好みにあった空調制御を行うようにしている。
【０００４】
【発明が解決しようとする課題】
しかしながら、前者の従来装置においては、予め決められた制御特性が乗員の好みに合わない場合、空調に不満がでるたびに送風量や設定温度等を調整する空調操作を行う必要がある。また、乗員が行った空調操作の情報に基づいて制御特性を補正する、いわゆる学習制御を行う場合でも、学習制御のベースとなる制御特性が乗員の好みから大きく離れていると、乗員の好みに合った制御特性に近づくのが遅くなるという問題があった。
【０００５】
一方、後者の従来装置においては、各空調対象者が空調操作を行うまでは、各空調対象者の好みにあった空調制御を行うことができないという問題があった。
【０００６】
本発明は上記の点に鑑みてなされたもので、車室内の空調状態を制御特性に基づいて自動制御する車両用空調装置において、乗員が空調操作を行わなくても、ほぼ乗員の好みにあった空調制御が行われるようにすることを目的とする。
【０００７】
【課題を解決するための手段】
上記目的を達成するため、請求項１に記載の発明では、車室内の空調状態を制御特性に基づいて自動制御する制御手段（３１）を備える車両用空調装置において、乗員の操作により乗員の個人情報を入力する入力手段（５０）を備え、入力手段（５０）は、少なくとも個人情報の１つとして乗員の年齢を入力可能に構成され、制御手段（３１）は、制御特性として複数の制御特性を有し、個人情報に基づいて乗員が所定年齢を超える高齢者であるか否かを判定し、乗員が高齢者である場合は高齢者の好む傾向の制御特性を、複数の制御特性の中から選択することを特徴とする。
【０００８】
これによると、例えば、高齢者は風速感を嫌がって低風量を好み、髪の長い人は髪が乱れるのを嫌って低風量を好み、また、コンタクトレンズ着用者は目が乾きやすいため低風量を好み、メガネ着用者は目が乾きにくく風速感を楽しむために高風量を好み、若い人は風速感を好むというような傾向があるため、乗員の個人情報からその乗員に対して最適と思われる制御特性を選択することにより、乗員が空調操作を行わなくても、その乗員の好みにあった空調制御を行うことができる。

【００５５】
なお、上記各手段の括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示すものである。
【００５６】
【発明の実施の形態】
（第１実施形態）
図１は本発明の第１実施形態になる車両用空調装置の全体システム構成を示すもので、この車両用空調装置は、記憶された制御特性に基づいて空調制御用機器の作動を自動制御して、吹出温度、送風量、吸込モード、吹出モード等を自動制御すると共に、記憶された制御特性を乗員の空調操作に基づいて補正、すなわち学習するものである。
【００５７】
車両用空調装置の室内ユニットを構成する空調ユニット１０の空気流れ最上流側には、吸込モード切替手段としての内外気切替箱１１が配置され、この内外気切替箱１１は外気導入口１１ａと内気導入口１１ｂを有すると共に、この内外気切替箱１１内に内外気切替ドア１２が回動自在に設置されている。
【００５８】
この内外気切替ドア１２は、外気導入口１１ａと内気導入口１１ｂとの分岐点に配置され、アクチュエータ１２ａにより駆動されて、空調ユニット１０に導入する空気を内気と外気に切り替えたり、あるいは内気と外気の混合割合を調整する。
【００５９】
内外気切替箱１１の下流には送風手段としての送風機１３が配置され、この送風機１３は、内外気切替箱１１内に空気を吸い込んで空調ユニット１０の下流側に送風するものであり、ブロワモータ１４と、その回転軸に連結された遠心式送風ファン１５を有している。この送風ファン１５の下流にはエバポレータ１６とヒータコア１７が設けられている。
【００６０】
エバポレータ１６は冷却用熱交換器であって、図示しない車両エンジンにより駆動されるコンプレッサ等と結合されて冷凍サイクルを構成し、その内部の低圧冷媒が空気から吸熱して蒸発することにより空気を冷却する。また、ヒータコア１７は加熱用熱交換器であって、図示しない車両エンジンの冷却水（温水）が内部を循環し、このエンジン冷却水を熱源として空気を加熱する。
【００６１】
ヒータコア１７の上流側には、吹出空気温度調整手段としてのエアミックスドア１８が回動自在に設けられ、エアミックスドア１８の開度はアクチュエータ１８ａにより駆動されて調節される。これによって、ヒータコア１７を通過する空気とヒータコア１７をバイパスする空気の割合とが調整され、車室内に吹き出す空気の温度が調整される。
【００６２】
空調ユニット１０の最下流には、デフロスタ（ＤＥＦ）吹出口１９を開閉するデフロスタドア２０、フェイス（ＦＡＣＥ）吹出口２１を開閉するフェイスドア２２、およびフット（ＦＯＯＴ）吹出口２３を開閉するフットドア２４が設けられている。
【００６３】
これら各ドア２０、２２、２４は吹出モード切替手段を構成するもので、アクチュエータ２５により駆動されて各吹出口１９、２１、２３を開閉することによって、各種の吹出モード、すなわち、フェイスモード、バイレベルモード、フットモード、フットデフモード、デフロスタモード等が設定される。そして、各吹出モードに応じて開口した吹出口から、温度調整された空気が車室内へ吹き出される。
【００６４】
空調制御装置３０は制御手段としてのマイクロコンピュータ３１を有し、送風量は、マイクロコンピュータ３１からの出力信号に基づいて駆動回路３２を介してブロワモータ１４の印加電圧（ブロワ電圧）を調整してモータ回転数を調整することにより制御される。なお、その他のアクチュエータ１２ａ、１８ａ、２５も、マイクロコンピュータ３１からの出力信号に基づいて駆動回路３２を介して制御される。
【００６５】
マイクロコンピュータ３１は図示しない中央演算処理装置（ＣＰＵ）、ＲＯＭ、ＲＡＭ、スタンバイＲＡＭ、Ｉ／Ｏポート、Ａ／Ｄ変換部等を持ち、それ自体は周知のものである。
【００６６】
スタンバイＲＡＭは、車両エンジンの運転を断続するイグニションスイッチ（以下、ＩＧと記す）オフの場合においても乗員の好みを学習した値を記憶（バックアップ）するためのＲＡＭであり、ＩＧがオフであっても車載バッテリーからＩＧを介さずに直接電力が供給される。また、マイクロコンピュータ３１とバッテリーとの電気接続が遮断された状況でも短時間ならばマイクロコンピュータ３１に電力を供給する図示しないバックアップ用の電源が設けられている。
【００６７】
マイクロコンピュータ３１には、車室内計器盤に設置された空調操作部３３から操作信号が入力される。この空調操作部３３には、空調装置の自動制御状態を設定するＡＵＴＯスイッチ３４、内外気吸込モードを手動で切替設定するための内外気切替スイッチ３５、吹出モードを手動で切替設定するための吹出モード切替スイッチ３６、送風機１３の送風量を手動で切替設定するための送風量切替スイッチ３７、乗員の好みの温度を設定するための温度設定スイッチ３８等が設けられている。
【００６８】
上記の内外気切替スイッチ３５、吹出モード切替スイッチ３６、送風量切替スイッチ３７、および温度設定スイッチ３８は、いずれも乗員の操作により希望の空調状態を設定する操作手段に相当する。そして、マイクロコンピュータ３１は、乗員がそれらのスイッチ３５〜３８により設定した空調操作情報に基づいて制御特性を補正する、いわゆる学習制御を行うようになっている。
【００６９】
なお、送風量切替スイッチ３７は、具体的には、風量アップスイッチ３７ａと風量ダウンスイッチ３７ｂからなり、風量アップスイッチ３７ａは１回押されるごとにブロワ電圧（駆動用モータ１４への印加電圧）を１レベル（０．２５ボルト）上げる信号を出力し、風量ダウンスイッチ３７ｂは１回押されるごとにブロワ電圧を１レベル（０．２５ボルト）下げる信号を出力する。
【００７０】
また、マイクロコンピュータ３１には、車室内の空調状態に影響を及ぼす環境条件（空調熱負荷）等を検出する各種センサからの信号が入力される。具体的には、車室内の空気温度（内気温度）ＴＲを検出する内気温センサ３９、車室外の空気温度（外気温度）ＴＡＭを検出する外気温センサ４０、車室内に入射する日射量ＴＳを検出する日射センサ４１、蒸発器温度（具体的には蒸発器吹出空気温度）ＴＥを検出する蒸発器温度センサ４２、ヒータコア１７を循環するエンジン水温ＴＷを検出する水温センサ４３、後席に設置されて後席乗員の有無を検出する後席乗員検出手段としてのシートセンサ４４等からの各信号が、それぞれのレベル変換回路４５を介してマイクロコンピュータ３１に入力され、これらはマイクロコンピュータ３１においてＡ／Ｄ変換されて読み込まれる。また、温度設定スイッチ３８からの信号もレベル変換回路４５でレベル変換されてマイクロコンピュータ３１に入力される。
【００７１】
また、マイクロコンピュータ３１には、カーナビゲーション装置５０が接続されている。カーナビゲーション装置５０は、自車の現在位置を表示する図示しないモニター画面を備え、乗員の髪の長さや年齢等の個人情報をモニター画面上で入力可能になっており、その個人情報がマイクロコンピュータ３１に出力されるようになっている。なお、カーナビゲーション装置５０は、乗員の操作により乗員の個人情報を入力する入力手段に相当する。
【００７２】
図２はマイクロコンピュータ３１により実行される本発明の全体のフローチャートであり、ＩＧオンとともに図２の制御をスタートする。まず、ステップＳ１にて各種変換、フラグ等の初期値を設定する。次のステップＳ２では空調操作部３３の各種スイッチ３４〜３８の操作信号、各種センサ３９〜４４からのセンサ検出信号、およびカーナビゲーション装置５０からの信号を読み込む。
【００７３】
次のステップＳ３では、ステップＳ２で読み込んだ設定温度ＴＳＥＴおよびセンサ検出信号等に基づいて車室内に吹き出す空気の目標吹出温度ＴＡＯを下記数式１により算出する。ここで、ＴＡＯは環境条件の変化にかかわらず車室内を設定温度ＴＳＥＴに維持するために必要な吹出空気温度である。
【００７４】
【数１】
ＴＡＯ＝ＫＳＥＴ×ＴＳＥＴ−ＫＲ×ＴＲ−ＫＡＭ×ＴＡＭ−ＫＳ×ＴＳ＋Ｃ
但し、ＫＳＥＴ、ＫＲ、ＫＡＭ、ＫＳは係数、Ｃは定数であり、ＴＳＥＴ、ＴＲ、ＴＡＭ、ＴＳはそれぞれ上記した設定温度、内気温度、外気温度、日射量である。
【００７５】
次に、ステップＳ４に進み、送風量を決めるブロワ電圧を上記ＴＡＯに基づいて決定する。ここで、乗員が望む風量には個人差があるので、一律に送風量を決めることは難しい。そこで、本実施形態では、送風量に関する乗員の手動操作に基づいて送風量制御特性としてのブロワ電圧算出マップを補正していくことにより、乗員の好みを学習したブロワ電圧算出マップとなるようにしている。
【００７６】
また、ブロワ電圧算出マップを複数有しており、乗員の個人情報に基づいて複数のブロワ電圧算出マップの中から１つを選択し、その選択したブロワ電圧算出マップに基づいてブロワ電圧を決定するようになっている。これらについては後で詳述する。
【００７７】
次に、ステップＳ５に進み、エアミックスドア１８の開度ＳＷを、ＴＡＯ、ＴＥ、ＴＷに基づいて算出する。次に、ステップＳ６に進み、内外気切替ドア１２による内気と外気の導入割合をＴＡＯに基づいて演算する。次に、ステップＳ７にて吹出モードドア２０、２２、２４による吹出モードをＴＡＯに基づいて演算する。次に、ステップＳ８において、蒸発器温度ＴＥが目標蒸発器温度に維持されるように、コンプレッサの制御を決定する。
【００７８】
次に、ステップＳ９に進み、上記各ステップＳ４〜Ｓ８で決定された各種制御信号を駆動回路３２を介してブロワモータ２４、各アクチュエータ１２ａ、１８ａ、２５およびコンプレッサに加えて、ブロワモータ２４の回転数、各アクチュエータ１２ａ、１８ａ、２５およびコンプレッサの作動を制御する。ステップＳ９の処理後ステップＳ２に戻り、上記処理を繰り返す。
【００７９】
図３、図４は図２のステップＳ４によるブロワ電圧決定の具体的処理を例示するもので、以下詳細に説明する。まず、図３の処理により、ステップＳ１８０に図示するパターン▲１▼〜▲６▼のブロワ電圧算出マップの中から、乗員の個人情報に基づいて１つが選択される。また、パターン▲１▼〜▲６▼のブロワ電圧算出マップは、各吹出モード毎に用意されている。また、それらのブロワ電圧算出マップは、乗員が最初に送風量切替スイッチ３７を操作する前に予め用意されている。
【００８０】

While having the introduction port 11b, the inside / outside air switching door 12 is rotatably installed in the inside / outside air switching box 11.
[0058]
The inside / outside air switching door 12 is arranged at a branch point between the outside air introduction port 11a and the inside air introduction port 11b and is driven by the actuator 12a to switch the air introduced into the air conditioning unit 10 between the inside air and the outside air, or between the inside air and the outside air. Adjust the mixing ratio of outside air.
[0059]
A blower 13 as a blower is disposed downstream of the inside / outside air switching box 11. The blower 13 sucks air into the inside / outside air switching box 11 and blows it to the downstream side of the air conditioning unit 10. And a centrifugal blower fan 15 connected to the rotating shaft. An evaporator 16 and a heater core 17 are provided downstream of the blower fan 15.
[0060]
The evaporator 16 is a heat exchanger for cooling, and is combined with a compressor or the like driven by a vehicle engine (not shown) to constitute a refrigeration cycle. The low-pressure refrigerant in the interior absorbs heat from the air and evaporates to cool the air. To do. The heater core 17 is a heat exchanger for heating, and cooling water (hot water) of a vehicle engine (not shown) circulates inside, and heats the air using the engine cooling water as a heat source.
[0061]
On the upstream side of the heater core 17, an air mix door 18 as a blown air temperature adjusting means is rotatably provided, and the opening degree of the air mix door 18 is adjusted by being driven by an actuator 18a. Thereby, the ratio of the air passing through the heater core 17 and the air bypassing the heater core 17 is adjusted, and the temperature of the air blown out into the passenger compartment is adjusted.
[0062]
At the most downstream side of the air conditioning unit 10, a defroster door 20 that opens and closes a defroster (DEF) outlet 19, a face door 22 that opens and closes a face (FACE) outlet 21, and a foot door 24 that opens and closes a foot (FOOT) outlet 23. Is provided.
[0063]
Each of these doors 20, 22, and 24 constitutes a blow mode switching means, and is driven by an actuator 25 to open and close the blow outlets 19, 21, and 23. Level mode, foot mode, foot differential mode, defroster mode, etc. are set. Then, the temperature-adjusted air is blown out into the passenger compartment from the blow-out opening that opens in accordance with each blowing mode.
[0064]
The air-conditioning control device 30 has a microcomputer 31 as control means, and the amount of blown air is adjusted by adjusting the applied voltage (blower voltage) of the blower motor 14 via the drive circuit 32 based on the output signal from the microcomputer 31. It is controlled by adjusting the rotation speed. The other actuators 12a, 18a, and 25 are also controlled via the drive circuit 32 based on the output signal from the microcomputer 31.
[0065]
The microcomputer 31 has a central processing unit (CPU), a ROM, a RAM, a standby RAM, an I / O port, an A / D conversion unit, and the like (not shown) and is well known per se.
[0066]
The standby RAM is a RAM for storing (backing up) a learned value of passengers even when an ignition switch (hereinafter referred to as IG) for intermittently driving the vehicle engine is off, and IG is off. Also, power is supplied directly from the on-board battery without going through the IG. Further, a backup power source (not shown) is provided for supplying power to the microcomputer 31 for a short time even when the electrical connection between the microcomputer 31 and the battery is interrupted.
[0067]
An operation signal is input to the microcomputer 31 from an air conditioning operation unit 33 installed in the vehicle interior instrument panel. The air conditioning operation unit 33 includes an AUTO switch 34 for setting an automatic control state of the air conditioner, an inside / outside air changeover switch 35 for manually setting the inside / outside air suction mode, and a blowout for manually setting the blowout mode. A mode changeover switch 36, an airflow changeover switch 37 for manually setting the airflow of the blower 13, a temperature setting switch 38 for setting a passenger's favorite temperature, and the like are provided.
[0068]
The inside / outside air changeover switch 35, the blowout mode changeover switch 36, the air flow rate changeover switch 37, and the temperature setting switch 38 all correspond to operation means for setting a desired air conditioning state by the occupant's operation. And the microcomputer 31 performs what is called learning control which correct | amends a control characteristic based on the air-conditioning operation information which the passenger | crew set with those switches 35-38.
[0069]
The air volume switching switch 37 is specifically composed of an air volume up switch 37a and an air volume down switch 37b. Each time the air volume up switch 37a is pressed, the blower voltage (applied voltage to the drive motor 14) is set. A signal that increases one level (0.25 volt) is output, and the air volume down switch 37b outputs a signal that decreases the blower voltage by one level (0.25 volt) each time it is pressed.
[0070]
In addition, the microcomputer 31 receives signals from various sensors that detect environmental conditions (air conditioning heat load) that affect the air conditioning state in the passenger compartment. Specifically, an inside air temperature sensor 39 that detects an air temperature (inside air temperature) TR in the vehicle interior, an outside air temperature sensor 40 that detects an air temperature outside the vehicle interior (outside air temperature) TAM, and an amount of solar radiation TS that enters the vehicle interior. A solar radiation sensor 41 for detecting, an evaporator temperature sensor 42 for detecting an evaporator temperature (specifically, an evaporator blown air temperature) TE, a water temperature sensor 43 for detecting an engine water temperature TW circulating in the heater core 17, and a rear seat.

The signal from the temperature setting switch 38 is also level-converted by the level conversion circuit 45 and input to the microcomputer 31.
[0071]
In addition, a car navigation device 50 is connected to the microcomputer 31. The car navigation device 50 includes a monitor screen (not shown) that displays the current position of the vehicle, and personal information such as the hair length and age of the occupant can be input on the monitor screen. 31 is output. Note that the car navigation device 50 corresponds to an input unit that inputs personal information of an occupant by an operation of the occupant.
[0072]
FIG. 2 is an overall flowchart of the present invention executed by the microcomputer 31, and the control of FIG. First, initial values such as various conversions and flags are set in step S1. In the next step S2, operation signals of various switches 34 to 38 of the air conditioning operation unit 33, sensor detection signals from various sensors 39 to 44, and signals from the car navigation device 50 are read.
[0073]
In the next step S3, the target blowing temperature TAO of the air blown into the vehicle interior is calculated by the following formula 1 based on the set temperature TSET read in step S2, the sensor detection signal, and the like. Here, TAO is the blown air temperature necessary for maintaining the passenger compartment at the set temperature TSET regardless of changes in environmental conditions.
[0074]
[Expression 1]
TAO = KSET × TSET-KR × TR-KAM × TAM-KS × TS + C
However, KSET, KR, KAM, and KS are coefficients, C is a constant, and TSET, TR, TAM, and TS are the set temperature, the inside air temperature, the outside air temperature, and the amount of solar radiation, respectively.
[0075]
Next, it progresses to step S4 and the blower voltage which determines ventilation volume is determined based on said TAO. Here, since there are individual differences in the air volume desired by the occupant, it is difficult to uniformly determine the air volume. Therefore, in the present embodiment, by correcting the blower voltage calculation map as the air flow control characteristic based on the passenger's manual operation related to the air flow, the blower voltage calculation map learning the passenger's preference is obtained. Yes.
[0076]
Also, a plurality of blower voltage calculation maps are provided, one of the plurality of blower voltage calculation maps is selected based on the passenger's personal information, and the blower voltage is determined based on the selected blower voltage calculation map. It is like that. These will be described in detail later.
[0077]
Next, it progresses to step S5 and the opening degree SW of the air mix door 18 is calculated based on TAO, TE, and TW. Next, it progresses to step S6 and calculates the introduction ratio of inside air and outside air by the inside / outside air switching door 12 based on TAO. Next, in step S7, the blowing mode by the blowing mode doors 20, 22, 24 is calculated based on TAO. Next, in step S8, control of the compressor is determined so that the evaporator temperature TE is maintained at the target evaporator temperature.
[0078]
Next, the process proceeds to step S9, and the various control signals determined in the above steps S4 to S8 are added to the blower motor 24, the actuators 12a, 18a, 25 and the compressor via the drive circuit 32, and the rotational speed of the blower motor 24. It controls the operation of each actuator 12a, 18a, 25 and compressor. After the process of step S9, the process returns to step S2 to repeat the above process.
[0079]
3 and 4 exemplify specific processing for determining the blower voltage in step S4 of FIG. 2, and will be described in detail below. First, one of the blower voltage calculation maps of the patterns (1) to (6) shown in step S180 is selected based on the passenger's personal information by the processing of FIG. Further, the blower voltage calculation maps of patterns (1) to (6) are prepared for each blowing mode. These blower voltage calculation maps are prepared in advance before the occupant first operates the air flow rate changeover switch 37.
[0080]
Incidentally, pattern (1) is a standard air flow rate characteristic, and pattern (2) is a relatively high air flow rate characteristic in which the air flow rate in the intermediate temperature range of TAO is larger than pattern (1). Pattern (3) is the characteristic of the highest air flow rate where the air flow rate in the temperature range of 10 to 39 ° C. is higher than that in pattern (2), and pattern (4) is the flow rate in the middle temperature range of TAO. The air flow rate characteristic is a relatively low air flow rate that is less than the pattern (1), and the pattern (5) is the lowest air flow rate that the air flow rate in the whole temperature range of the TAO is less than the pattern (1). The pattern {circle around (6)} is a characteristic of the air flow rate with a slightly lower air volume when the air flow rate in the low temperature range of the TAO is smaller than that of the pattern (1).
[0081]
In FIG. 3, in step S <b> 110, it is determined whether the air conditioning initial setting is selected on the monitor screen of the car navigation device 50. Incidentally, the initial setting of the air conditioning is performed when the vehicle gets on the vehicle for the first time or when the occupant changes. When the air conditioning initial setting is selected, personal information such as the length and age of the occupant's hair is input in a format that answers the question displayed on the monitor screen, and the following steps S120, 130, In 140, 150, and 160, determination is performed based on the personal information.
[0082]
When the air conditioning initial setting is selected and step S110 becomes YES, the process proceeds to step S120. In step S120, it is determined whether or not the occupant is an elderly person over 55 years old. If the occupant is an elderly person, step S120 is YES and the process proceeds to step S125. Since elderly people dislike the feeling of wind speed, in step S125, the blower voltage calculation map of the pattern (5) with the lowest air volume is selected.
[0083]
If step S120 is NO and the process proceeds to step S130, it is determined whether or not the occupant is wearing a contact lens, and if so, step S130 becomes YES and the process proceeds to step S135. Since the eyes are likely to dry when wearing the contact lens, a blower voltage calculation map of the pattern (4) having a relatively low air volume is selected in step S135.
[0084]
If step S130 is NO and the process proceeds to step S140, it is determined whether or not the passenger's hair is long. If it is long, step S140 becomes YES and the process proceeds to step S145.

[0085]
If step S140 is NO and the process proceeds to step S150, it is determined whether the person does not turn the wind toward the person or the person is wearing glasses. If step S150 is YES, the process proceeds to step S155, and the pattern ▲ 3) Select the blower voltage calculation map. Incidentally, in order to compensate for a warm feeling for a person who does not turn the wind, and because the eyeglass wearer tends to enjoy the feeling of wind speed because his eyes do not dry easily, the pattern (3) having the highest air volume is selected.
[0086]
If step S150 is NO and the process proceeds to step S160, it is determined whether or not the occupant is a young person under the age of 21, and if it is a young person, step S160 becomes YES and the process proceeds to step S165. Since young people tend to prefer the feeling of wind speed, in step S165, a blower voltage calculation map having a relatively high air volume pattern (2) is selected.
[0087]
When step S160 is NO, the process proceeds to step S175, and a blower voltage calculation map of pattern (1) which is a standard air flow rate characteristic is selected.
[0088]
In step S180, the blower voltage calculation map of the pattern selected by the above processing is determined as a blower voltage calculation map for determining subsequent blower voltages and a base blower voltage calculation map for learning control. A blower voltage calculation map is prepared for each blowing mode, and one blower voltage calculation map is selected from the blower voltage calculation maps of patterns (1) to (6) for each blowing mode.

This blower voltage calculation map is a blower voltage calculation map in the face mode determined in step S180 of FIG. Next, the process proceeds from step S212 to step S213, and the blower voltage is calculated based on the TAO from the blower voltage calculation map in the face mode. If step S211 is NO, the process immediately proceeds to step S213, and the blower voltage is calculated.
[0091]
If step S210 is NO, the process proceeds to step S220. In step S220, it is determined whether the current blowing mode is the bi-level (B / L) mode. If the blowing mode is the bi-level mode, step S220 is performed. It becomes YES and progresses to step S221. In step S221, it is determined whether or not the occupant has manually changed the airflow rate by operating the airflow rate changeover switch 37.

Next, the process proceeds from step S222 to step S223, and the blower voltage is calculated based on the TAO from the blower voltage calculation map in the bi-level mode. If step S221 is NO, the process immediately proceeds to step S223, and the blower voltage is calculated.
[0093]
If step S220 is NO, the process proceeds to step S230. In step S230, it is determined whether or not the current blowing mode is the foot (FOOT) mode. If the blowing mode is the foot mode, step S230 is YES and step S231 is performed. Proceed to In step S231, it is determined whether or not the occupant has manually changed the airflow rate by operating the airflow rate changeover switch 37.

In step S242, the blower voltage calculation map in the foot differential mode shown in FIG. 5D is corrected, that is, learned, based on the operation of the air flow rate switch 37. This blower voltage calculation map is a blower voltage calculation map in the foot differential mode determined in step S180 of FIG. Next, the process proceeds from step S242 to step S243, and the blower voltage is calculated based on TAO from the blower voltage calculation map in the foot differential mode. If step S241 is NO, the process immediately proceeds to step S243, and the blower voltage is calculated.
[0097]
If step S240 is NO, the process proceeds to step S251. Incidentally, when the process proceeds to step S251 from the mode determination results in steps S210 to S240, the current blowing mode is the defroster (DEF) mode. In step S251, it is determined whether or not the occupant has manually changed the airflow rate by operating the airflow rate changeover switch 37. If the airflow rate has been manually changed, step S251 becomes YES and the process proceeds to step S252. .
[0098]
In step S252, the blower voltage calculation map in the defroster mode shown in FIG. 5E is corrected, that is, learned, based on the operation of the air flow rate changeover switch 37. This blower voltage calculation map is a blower voltage calculation map in the defroster mode determined in step S180 of FIG. Next, the process proceeds from step S252 to step S253, and the blower voltage is calculated based on TAO from the blower voltage calculation map in the defroster mode. If step S251 is NO, the process immediately proceeds to step S253, and the blower voltage is calculated.
[0099]
As described above, by correcting the blower voltage calculation map corresponding to each blowing mode in steps S212, S222, S232, S242, and S252 based on the operation of the blowing amount changeover switch 37, the blast amount of the occupant is adjusted. Preference is learned.
[0100]
Here, an example of a specific learning method of the blower voltage calculation map in step S212 and the like will be described with reference to FIG. A characteristic A in FIG. 6A is a blower voltage calculation map determined in step S180 in FIG. 3, and when the occupant operation has not been learned about the air flow rate, the blower is determined according to the characteristic in FIG. 6A. A voltage is calculated.
[0101]
When the first operation of the air flow rate changeover switch 37 is performed by the occupant, the operation of the occupant is performed when the blower voltage is at a level (maximum air flow Hi) in the characteristic A of FIG. When the blower voltage is lowered to the level of the operating point 1, the occupant operation is learned, and the sloped portion of the characteristic A is moved to the left side (low temperature side of TAO) in FIG. Translate. A solid line B in FIG. 6A shows the control characteristics after learning the first passenger operation.
[0102]
Next, FIG. 6B shows learning by the second occupant operation. In the control characteristic B after the first learning, when the blower voltage is at the b level (small air volume close to the minimum air volume Lo), When the blower voltage is raised to the level of the operating point 2 by the occupant's operation, the inclination θ of the inclined portion of the control characteristic is changed so as to pass through both the operating point 1 and the operating point 2 this time. A solid line C in FIG. 6B shows the control characteristics after learning the second passenger operation.
[0103]
Next, FIG. 6C shows learning by the third occupant operation. In the control characteristic C after the second learning, the blower voltage is c level (the air flow rate at the operation point 2 and the minimum air flow rate Lo). When the blower voltage is lowered to the Lo level of the minimum airflow at the operating point 3 by the occupant's operation, the inclination θ of the inclined portion in the control characteristic C after the second learning is now obtained. Then, the operating point 1, the operating point 2 and the operating point 3 are changed to a slope that approximates the least square. Therefore, the control characteristic after learning the third passenger operation is as shown by a solid line D in FIG. For occupant operations four or more times, each operation point is changed to a slope that approximates the least square.
[0104]
In this embodiment, in the air conditioner that automatically controls the air flow based on the air flow control characteristics, the air flow control characteristic has a plurality of control characteristics as the air flow control characteristics, and is optimal for the occupant based on personal information such as age. Since the possible control characteristics are selected, the air conditioning control suited to the passenger's preference can be performed without the passenger performing the air conditioning operation.
[0105]
In addition, when learning the air flow control characteristics, learning is performed based on the control characteristics selected based on personal information, that is, control characteristics close to the passenger's preference. Can be characteristic.
[0106]
Further, by selecting one of a plurality of control characteristics prepared in advance before the occupant first operates the blast amount switch 37, the occupant has not operated the blast amount switch 37 even once. Even in the state, it is possible to perform the air conditioning control that almost matches the passenger's preference.
