Description

本発明は、アイドルストップ機能付きの車両に用いられる車両用空調装置に関し、特にアイドルストップ状態における室内の空調快適性の向上を達成することができるものに関する。   The present invention relates to a vehicle air conditioner for use in a vehicle with an idle stop function, and more particularly to an apparatus capable of improving indoor air conditioning comfort in an idle stop state.

近年、環境保護を目的にして、信号待ち時等の停車時（エンジン動力不要時）にエンジンを自動的に停止させ、発進時に自動的に再始動させて円滑に発進させるようにした、いわゆるアイドルストップ機能付きの車両（以下、「ＩＤ車両」と称する）が実用化されている。   In recent years, for the purpose of environmental protection, the so-called idle system has been designed so that the engine is automatically stopped when the vehicle is stopped (when the engine power is not required), such as when waiting for a signal, and restarted smoothly when starting. Vehicles with a stop function (hereinafter referred to as “ID vehicles”) have been put into practical use.

一方、車両には室内の温度、湿度、送風、換気等の調整を行うための空調装置が搭載されており、この空調装置のエアコンユニットは、ベンチレータ（換気機能）とヒータ（暖房機能）とクーラ（冷房・除湿機能）とによって構成されている。   On the other hand, the vehicle is equipped with an air conditioner for adjusting indoor temperature, humidity, ventilation, ventilation, etc. The air conditioner unit of this air conditioner includes a ventilator (ventilation function), a heater (heating function), and a cooler. (Cooling / dehumidification function).

このようなＩＤ車両では、例えば、シフトレバーの位置、車速０状態の一定時間継続、ブレーキスイッチのＯＮ等がエンジンの停止条件となり、このエンジンの停止条件が成立したらエンジンを自動停止する（エコロジカル制御）。ところが、上述した空調装置が作動していた場合、エンジンが停止するとエアコンのコンプレッサやウォータポンプも停止するため、冷房機能及び暖房機能が作用せずに乗員に不快感を与えてしまう。そのため、アイドルストップ制御装置では、従来、エンジンの停止条件が成立しても空調装置を作動させたい場合にはエンジンを停止させないようにしており、アイドルストップ機能が十分に発揮できない。   In such an ID vehicle, for example, the position of the shift lever, the continuation of the vehicle speed 0 state for a certain period of time, the ON of the brake switch, etc. are the engine stop conditions, and the engine is automatically stopped when this engine stop condition is satisfied (ecological) control). However, when the above-described air conditioner is operating, the compressor and the water pump of the air conditioner are also stopped when the engine is stopped. Therefore, the cooling function and the heating function are not activated, and the passenger is uncomfortable. For this reason, in the conventional idle stop control device, the engine is not stopped when it is desired to operate the air conditioner even if the engine stop condition is satisfied, and the idle stop function cannot be sufficiently exhibited.

そこで、例えば、エアコンが作動された状態でエンジンの自動停止条件が成立するとエンジンを自動停止させるが、そのエンジンの自動停止条件として、ボンネットの閉止、冷却水温度が所定範囲内、バッテリの充電量が所定電圧以上、変速機のニュートラル、駐車ブレーキの作動、アイドル運転時間の所定時間の継続に加え、車室内温度が所定範囲内にあることを入れており、車室内温度が所定範囲内にあれば、エンジンを自動停止しても乗員に不快感を与えることはなく、かつ、十分な排気ガス対策や燃費向上が図ることができる（例えば、特許文献１，２参照）。
特開平１１−４４２３０号公報 特開２００６−２４０４５９号公報 Therefore, for example, when the engine automatic stop condition is satisfied while the air conditioner is operated, the engine is automatically stopped. As the engine automatic stop condition, the hood is closed, the cooling water temperature is within a predetermined range, the battery charge amount Is not less than the specified voltage, transmission neutral, parking brake operation, continuation of the idle operation time for a predetermined time, the vehicle interior temperature is within the predetermined range, and the vehicle interior temperature is within the predetermined range. For example, even if the engine is automatically stopped, passengers are not uncomfortable, and sufficient exhaust gas countermeasures and fuel efficiency improvements can be achieved (see, for example, Patent Documents 1 and 2).
Japanese Patent Laid-Open No. 11-44230 JP 2006-240459 A

上述した車両用空調装置では、次のような問題があった。すなわち、エアコンユニットは、ベンチレータとヒータとクーラを温調ダンパ（エアミックスダンパ）を用いてバランスさせて室内を快適に保つようにしている。このため、室内が快適に冷えた状態でアイドルストップが行われると、温調ダンパの変位がエアコン作動時のまま停止する。したがって、外気温が高い場合には、外気がヒータを経由して室内に流入する場合があり、時間経過とともに室内温度が上昇し、乗員が不快に感じることがある。このため、乗員は設定温度を変えた為にアイドルストップ時間が短縮されるとは限らない為、”乗員が強制的に
アイドルストップを解除してしまうことになり、エンジンが再始動し、アイドルストップ時間が短縮されてしまうという問題があった。 The vehicle air conditioner described above has the following problems. That is, the air conditioner unit keeps the room comfortable by balancing the ventilator, the heater, and the cooler using a temperature control damper (air mix damper). For this reason, when the idle stop is performed in a state where the room is comfortably cooled, the displacement of the temperature adjustment damper is stopped while the air conditioner is operating. Therefore, when the outside air temperature is high, the outside air may flow into the room via the heater, the room temperature may increase with time, and the passenger may feel uncomfortable. For this reason, the occupant forcibly cancels the idle stop time because the set temperature is changed. There was a problem that time was shortened.

そこで、本発明は、室内の空調快適性の向上とアイドルストップ時間の延長を達成することができる車両用空調装置を提供することを目的とする。   Therefore, an object of the present invention is to provide a vehicle air conditioner that can improve indoor air-conditioning comfort and extend idle stop time.

前記の課題を解決する第１の発明（請求項１に対応）に係る車両用空調装置は、運転状態・空調状態に応じてエンジンを自動停止または自動始動させるエンジン自動始動停止手段を有する車両に設けられる車両用空調装置において、上記車両の外気の温度を検出する外気温度検出部と、上記エンジンの自動停止が行われているか否かを判定する判定部と、室内温度を設定し、設定温度を出力する設定スイッチと、上記外気の温度が所定温度以上の場合は、調和前空気を室内に取り込むための温調ダンパを蒸発器側位置へ変位させ、上記外気の温度が所定温度より低い場合は、上記温調ダンパを上記蒸発器側位置とヒータコア側位置との間の上記設定温度に対応する位置へ変位させるダンパ制御部とを備えていることを特徴とする。   A vehicle air conditioner according to a first aspect of the present invention (corresponding to claim 1) that solves the above-described problem is provided in a vehicle having an engine automatic start / stop means for automatically stopping or automatically starting an engine according to an operation state / air conditioning state. In the vehicle air conditioner provided, an outside air temperature detection unit that detects the temperature of the outside air of the vehicle, a determination unit that determines whether or not the engine is automatically stopped, a room temperature is set, and a set temperature If the outside air temperature is higher than or equal to a predetermined temperature, the temperature adjustment damper for taking the pre-conditioning air into the room is displaced to the evaporator side position, and the outside air temperature is lower than the predetermined temperature. Comprises a damper control section for displacing the temperature control damper to a position corresponding to the set temperature between the evaporator side position and the heater core side position.

請求項１に記載された発明によれば、外気温が高い場合であっても室内温度を低く保つことが可能になり、アイドルストップ時の乗員の快適性を維持し、アイドルストップ時間を延長することが可能となる。   According to the first aspect of the present invention, it is possible to keep the indoor temperature low even when the outside air temperature is high, maintain passenger comfort during idling stop, and extend idling stop time. It becomes possible.

図１は本発明の一実施の形態に係る車両用空調装置３０が組み込まれた車両１０を模式的に示す説明図、図２は温調ダンパ制御のフローチャートを示す説明図である。   FIG. 1 is an explanatory view schematically showing a vehicle 10 in which a vehicle air conditioner 30 according to an embodiment of the present invention is incorporated, and FIG. 2 is an explanatory view showing a flowchart of temperature control damper control.

車両１０は、走行駆動機構２０と、車両用空調装置３０と、車両１０の各部を総合的に制御するＥＣＵ（電子コントロールユニット）１００とを備え、信号待ちなどで車両が停止する所定の条件になると、エアコンがＯＮ状態であっても、エンジン２１を自動的に停止してアイドリングストップ状態とすることで、燃費向上のためのエコロジカル制御が行われている。   The vehicle 10 includes a travel drive mechanism 20, a vehicle air conditioner 30, and an ECU (electronic control unit) 100 that comprehensively controls each part of the vehicle 10. Thus, even when the air conditioner is in the ON state, the engine 21 is automatically stopped to enter the idling stop state, thereby performing ecological control for improving fuel efficiency.

走行駆動機構２０は、エンジン２１と、エンジン２１を冷却するラジエータ機構２２と、このラジエータ機構２２を冷却する冷却ファン２３とを備えている。なお、ラジエータ機構２２は後述するヒータコア４７と接続されている。   The travel drive mechanism 20 includes an engine 21, a radiator mechanism 22 that cools the engine 21, and a cooling fan 23 that cools the radiator mechanism 22. The radiator mechanism 22 is connected to a heater core 47 described later.

車両用空調装置３０は、空調ユニット４０と、空調制御部５０とを備えている。空調ユニット４０は、ダクト４１と、エンジン２１によって駆動するコンプレッサ４２と、このコンプレッサ４２に連結されたコンデンサ４３と、このコンデンサ４３にレシーバ４４を介して接続された膨張弁４５及び蒸発器４６と、ラジエータ機構２２に接続されたヒータコア４７と、ダクト４１内に空気を通流させるファン４８と、取り入れられた調和前空気を蒸発器４６側の流路とヒータコア４７側の流路の間で変位させる温調ダンパ４９とを備えている。   The vehicle air conditioner 30 includes an air conditioning unit 40 and an air conditioning control unit 50. The air conditioning unit 40 includes a duct 41, a compressor 42 driven by the engine 21, a condenser 43 connected to the compressor 42, an expansion valve 45 and an evaporator 46 connected to the condenser 43 via a receiver 44, The heater core 47 connected to the radiator mechanism 22, the fan 48 for allowing air to flow through the duct 41, and the introduced pre-conditioning air are displaced between the flow path on the evaporator 46 side and the flow path on the heater core 47 side. And a temperature control damper 49.

空調ユニット４０は、コンプレッサ４２によって低圧ガス状の冷媒が圧縮されて高温高圧のガスとなり、コンデンサ４３で走行風やファン４８によって冷却されて液化され、高圧液状の冷媒が膨張弁４５によって急激に膨張して霧化しやすくなり、蒸発器４６で周囲のフィンから熱を奪ってガス状冷媒となる。この気化の際に熱を大量に奪って冷却を行い、再び低圧ガス状の冷媒となってコンプレッサ４２に戻され、冷凍サイクルが構成される。一方、ヒータコア４７は、暖房モードのときエンジン２１の冷却水を熱源として空気を加熱する機能を有している。   In the air conditioning unit 40, the low-pressure gaseous refrigerant is compressed into a high-temperature and high-pressure gas by the compressor 42, and is cooled and liquefied by the running air or the fan 48 by the condenser 43. The high-pressure liquid refrigerant is rapidly expanded by the expansion valve 45. It becomes easy to atomize, and the evaporator 46 takes heat from the surrounding fins to become a gaseous refrigerant. During this vaporization, a large amount of heat is taken for cooling, and the refrigerant is again converted into a low-pressure gaseous refrigerant and returned to the compressor 42 to constitute a refrigeration cycle. On the other hand, the heater core 47 has a function of heating air using the cooling water of the engine 21 as a heat source in the heating mode.

ダクト４１内には温度センサ５１が設けられ、空調吹出温度として空調制御部５０に入力され、車両停止時におけるアイドリングストップの条件が判断される。また、外気温センサ５２及び設定スイッチ５３が空調制御部５０に接続されている。空調制御部５０は、温調ダンパ４９の変位・開度を調節するダンパ制御部及びエンジン２１の自動停止が行われているか否かを判定する判定部を構成している。   A temperature sensor 51 is provided in the duct 41 and is input to the air conditioning control unit 50 as an air conditioning outlet temperature, and an idling stop condition when the vehicle is stopped is determined. An outside air temperature sensor 52 and a setting switch 53 are connected to the air conditioning control unit 50. The air conditioning control unit 50 constitutes a damper control unit that adjusts the displacement / opening of the temperature control damper 49 and a determination unit that determines whether or not the engine 21 is automatically stopped.

ＥＣＵ１００には、車速センサ１０１や図示しないエンジン回転数センサ、アクセル開度センサ、エアフローセンサ等の各種センサ類が接続されており、これらセンサ類からの検出情報に基づいて演算された燃料噴射量や点火時期等の最適値により、適正量の燃料が適正なタイミングで噴射され、点火プラグによって適正なタイミングで点火が実施される。 また、ＥＣＵ１００は各種センサ類からの検出情報に基づいてエンジン２１の運転状態に応じてこのエンジン２１をアイドリングストップまたは自動始動させる制御を行っている（エコロジカル制御）。すなわち、車両１０が信号でアイドル状態で停止しているとき、所定のアイドリングストップ条件、例えば、シフトレバーの位置、車速０状態の一定時間継続、ブレーキスイッチのＯＮ等の停止条件が成立したらエンジンを自動停止する。そして、所定のエンジン始動条件、例えば、クラッチペダルの踏み込み、シフトレバーの走行位置等の始動条件が成立したらエンジンを再始動する。   The ECU 100 is connected to various sensors such as a vehicle speed sensor 101, an engine speed sensor (not shown), an accelerator opening sensor, and an airflow sensor. The fuel injection amount calculated based on the detection information from these sensors, An appropriate amount of fuel is injected at an appropriate timing according to an optimum value such as an ignition timing, and ignition is performed at an appropriate timing by an ignition plug. Further, the ECU 100 performs control for idling stop or automatic start of the engine 21 in accordance with the operation state of the engine 21 based on detection information from various sensors (ecological control). That is, when the vehicle 10 is stopped in an idle state by a signal, the engine is started when a predetermined idling stop condition, for example, a shift lever position, a vehicle speed 0 state continuation for a certain period of time, a brake switch ON, or the like is satisfied. Stop automatically. When a predetermined engine start condition, for example, a start condition such as depression of a clutch pedal, travel position of a shift lever, or the like is satisfied, the engine is restarted.

一方、空調制御部５０では、温度条件等の各種の条件によってエンジン２１のアイドリングストップの可否を判定するとともに、ＥＣＵ１００からの情報に基づいて現時点でアイドリングストップしているか否かを判定すする。また、アイドリングストップ時においては、次のような制御を行う。すなわち、外気の温度が２５℃以上の場合は、温調ダンパ４９を蒸発器４６側位置へ変位させ、外気の温度が２５℃より低い場合は、温調ダンパ４９を蒸発器４６側位置とヒータコア４７側位置との間であって設定スイッチ５３によって設定された設定温度に対応する位置へ変位させる。   On the other hand, the air conditioning control unit 50 determines whether or not the engine 21 can be idling stopped based on various conditions such as a temperature condition, and determines whether or not idling is stopped at the present time based on information from the ECU 100. Further, at the time of idling stop, the following control is performed. That is, when the temperature of the outside air is 25 ° C. or higher, the temperature adjustment damper 49 is displaced to the evaporator 46 side position, and when the temperature of the outside air is lower than 25 ° C., the temperature adjustment damper 49 is moved to the evaporator 46 side position and the heater core. It is displaced to a position corresponding to the set temperature set by the setting switch 53 between the position on the 47 side.

このように構成された車両用空調装置３０は、以下のようにして温調ダンパ４９の制御を行う。なお、以下の説明は、空調スイッチが既にＯＮとなっている状態として説明する。また、車両用空調装置３０を作動させるためのコンプレッサ４２は、アイドルストップに連動する。   The vehicle air conditioner 30 configured as described above controls the temperature control damper 49 as follows. The following description will be made assuming that the air conditioning switch is already ON. Moreover, the compressor 42 for operating the vehicle air conditioner 30 is linked to idle stop.

アイドルストップ制御（エンジン制御）において、図２のフローチャートに示すように、エンジン２１がアイドルストップしているか否かを判定し（ＳＴ１０）、アイドルストップしていなければ、設定温度に合わせた温調ダンパ４９の制御を行う（ＳＴ１３）。すなわち、温調ダンパ４９を蒸発器４６側位置とヒータコア４７側位置との間であって設定スイッチ５３によって設定された設定温度に合わせて変位させる。   In the idle stop control (engine control), as shown in the flowchart of FIG. 2, it is determined whether or not the engine 21 is idle stopped (ST10). 49 is controlled (ST13). That is, the temperature control damper 49 is displaced between the evaporator 46 side position and the heater core 47 side position in accordance with the set temperature set by the setting switch 53.

一方、アイドルストップしていれば、外気温が２５℃以上か否かが判定される（ＳＴ１１）。外気温が２５℃より低ければ、上述したＳＴ１３の制御が行われる。   On the other hand, if the idling stop is performed, it is determined whether or not the outside air temperature is 25 ° C. or higher (ST11). If the outside air temperature is lower than 25 ° C., the above-described control of ST13 is performed.

外気温２５℃以上であれば、温調ダンパ４９を蒸発器４６側の最大位置（ＭＡＸ−ＣＯＯＬ）に変位させる（ＳＴ１２）。   If the outside air temperature is 25 ° C. or higher, the temperature adjustment damper 49 is displaced to the maximum position (MAX-COOL) on the evaporator 46 side (ST12).

このように、外気温によって温調ダンパ４９の変位を切り替えることで、外気温が高い時には外気をヒータユニット４７を経由させることなく、蒸発器４６側を通すことで、アイドルストップした直後であっても室内温度を低く維持させることができる。このため、乗員の快適性を維持し、アイドルストップ時間を延長させることができる。   In this way, by switching the displacement of the temperature adjustment damper 49 according to the outside air temperature, when the outside air temperature is high, the outside air is not passed through the heater unit 47, but passed through the evaporator 46 side, and immediately after the idling stop. The room temperature can be kept low. For this reason, a passenger | crew's comfort can be maintained and idle stop time can be extended.

このように本実施の形態に係る車両用空調装置３０によれば、外気の温度が２５℃以上の場合は、温調ダンパ４９を蒸発器４６側位置へ変位させ、外気の温度が２５℃より低い場合は、温調ダンパ４９を蒸発器４６側位置とヒータコア４７側位置との間であって設定スイッチ５３によって設定された設定温度に対応する位置へ変位させることで、乗員の快適性を維持し、アイドルストップ時間を延長させることができる。   Thus, according to the vehicle air conditioner 30 according to the present embodiment, when the temperature of the outside air is 25 ° C. or more, the temperature adjustment damper 49 is displaced to the evaporator 46 side position, and the temperature of the outside air is more than 25 ° C. When the temperature is low, the temperature control damper 49 is displaced between the evaporator 46 side position and the heater core 47 side position and to a position corresponding to the set temperature set by the setting switch 53, thereby maintaining passenger comfort. In addition, the idle stop time can be extended.

なお、本発明は上記実施の形態に限定されるものではない。例えば、上述した例では、外気温が２５℃以上か否かで判断しているが、２５℃に限られない。この他、本発明の要旨を逸脱しない範囲で種々変形実施可能である。   The present invention is not limited to the above embodiment. For example, in the above-described example, the determination is made based on whether or not the outside air temperature is 25 ° C. or higher, but is not limited to 25 ° C. In addition, various modifications can be made without departing from the scope of the present invention.
