Description

この発明は、空調制御装置に係り、特に電気自動車（ＥＶ）やハイブリッド車両（ＨＥＶ）等の電動車両における空調制御を行う空調制御装置に関する。   The present invention relates to an air conditioning control device, and more particularly to an air conditioning control device that performs air conditioning control in an electric vehicle such as an electric vehicle (EV) or a hybrid vehicle (HEV).

ＥＶ（電気自動車）車両、ＨＥＶ（ハイブリッド）車両等の電動車両は、バッテリ残量が低下すると、車両走行を優先するため、補助ヒータ（ＰＴＣ）、電動コンプレッサ等の空調機器の制限が必要とされる。この空調機器の制限が行なわれる場合、車両走行状態、発電状態（ＨＥＶ車両の場合）に関わらず、暖房、冷房が共に、最低駆動状態（電動コンプレッサは最小（Ｍｉｎ）電力値、補助ヒータは最小（Ｍｉｎ）電力値）に制限されるため、乗員が操作するパネル状態、外気温度等で決まる冷房、暖房性能に必要とされる電力が異なる場合でも、一律して動作を制限させている。   Since electric vehicles such as EV (electric vehicle) vehicles and HEV (hybrid) vehicles prioritize vehicle travel when the remaining battery level decreases, restrictions on air conditioning equipment such as auxiliary heaters (PTC) and electric compressors are required. The When this air conditioner is restricted, heating and cooling are both in the lowest drive state (minimum (Min) power value for the electric compressor) and auxiliary heater is the minimum regardless of the vehicle running state and the power generation state (in the case of HEV vehicles). Therefore, even if the power required for the cooling and heating performance determined by the panel state operated by the occupant, the outside air temperature, etc. is different, the operation is uniformly restricted.

即ち、電力の制限実行の肯定／否定だけの粗い判断に基づく結果としての空調制御は、空調制御の駆動制御量の通常値を単純制限した値を制限時の駆動制御量とし、条件が異なるあらゆる状態でも一律に行われている。
ところで、空調装置における噴出口を選択するモードが、防曇性（曇り止め性能）を高めるデフロスタモードや、デフロスタ＆フットモード（Ｄ／Ｆモード）の場合、空気に含まれる湿気（水蒸気）を凝縮させるために、空調装置の冷房サイクルシステム部を構成する冷房機器を駆動するとともに、この冷房サイクルシステム部によって冷却された空気の温度を目的の噴出温度に上昇させるために、空調装置の暖房機器を駆動するように制御している。 In other words, the air conditioning control as a result based on a rough judgment based only on affirmative / negative execution of power restriction is a simple restriction of the normal value of the drive control amount of the air conditioning control as the drive control amount at the time of restriction. Even in the state is done uniformly.
By the way, when the mode for selecting the jet outlet in the air conditioner is the defroster mode or the defroster & foot mode (D / F mode) that enhances the antifogging property (antifogging performance), moisture (water vapor) contained in the air is condensed. In order to increase the temperature of the air cooled by the cooling cycle system unit to the target ejection temperature, the heating device of the air conditioning unit is It is controlled to drive.

特開１９９７−７６７４０号公報JP 1997-76740 A 特許第３７９１２３４号公報Japanese Patent No. 3791234

特許文献１に係るハイブリッド車両は、駆動用の電気モータに電力を供給するバッテリから冷房ユニットに電力を送って冷房を行うものである。
特許文献２に係るハイブリッド車用空調装置は、室内を設定温度に調整するためにエアコンユニットが必要とする空調必要電力を演算し、車両走行中に、空調必要電力の増加に伴ってバッテリ残量の目標値を高く設定するものである。 The hybrid vehicle according to Patent Document 1 performs cooling by sending electric power from a battery that supplies electric power to a driving electric motor to a cooling unit.
The air conditioner for a hybrid vehicle according to Patent Document 2 calculates the required air conditioning power required by the air conditioner unit to adjust the room to a set temperature, and the remaining battery capacity as the required air conditioning power increases during vehicle travel. Is set to a high target value.

ところが、従来、夏場に、暖房機器である補助ヒータを使用せず、冷房機器である電動コンプレッサのみ必要とする場合でも、最小（Ｍｉｎ）電力値でしか駆動させることができず、本来、補助ヒータの駆動電力分を電動コンプレッサ側に加算させることができるにも関わらず、電動コンプレッサは最小（Ｍｉｎ）電力値に制限されてしまう。また、バッテリ残量がまだある場合、又は、ハイブリッド（ＨＥＶ）車両のように発電が可能な場合にも、空調機器の動作を全て停止させる等の制限を行ってしまう不具合があった。
また、デフロスタモードやデフロスタ＆フットモード（Ｄ／Ｆモード）の場合、冷房機器の駆動と暖房機器の駆動を同時に行う必要があり、冷房と暖房の両方のシステムに電力を必要とするため、極めて消費電力が多くなる。そして、瞬間的には車両の駆動力に費やす電力に影響を与える可能性があり、長時間にわたれば航続距離を大きく減らすことに繋がるので、車両走行に影響を与える可能性が他のモードに比べ高いといえる。そのため、電力制限によって実質的な機能を損ない易い反面、電力制限によって実質的に機能しなくなると防暑性が下がることになる。走行時の視界確保の観点から、特定の条件下で防暑性が下がることを避け、空調性能を確保したい都合がある。
更に、制限実行の肯定／否定だけの粗い判断に基づく結果としての空調制御では、空調装置の運転条件等の詳細な判断を行っておらず、詳細な判断に基づいて電力配分を変更する空調制御を行っていない。
空調が消費する電力を抑制した分に応じて、航続距離を延ばすことはできるが、航続距離に必要な電力が確保されていても、快適性を著しく損ねてしまう空調制御となってしまうことがあった。 However, conventionally, in the summer, when an auxiliary heater that is a heating device is not used and only an electric compressor that is a cooling device is required, it can be driven only with a minimum (Min) power value. However, the electric compressor is limited to the minimum (Min) electric power value even though the drive electric power can be added to the electric compressor side. In addition, there is a problem in that, for example, the operation of the air-conditioning apparatus is completely stopped even when the remaining amount of the battery is still present or when power generation is possible as in a hybrid (HEV) vehicle.
In the case of the defroster mode and the defroster & foot mode (D / F mode), it is necessary to drive the cooling device and the heating device at the same time, and both the cooling and heating systems require electric power. Power consumption increases. In addition, there is a possibility that the power consumed for the driving force of the vehicle may be instantaneously affected, and the cruising distance will be greatly reduced over a long period of time. Compared to high. Therefore, although it is easy to impair the substantial function due to the power limitation, the heat resistance is lowered when the function is not substantially limited due to the power limitation. From the viewpoint of ensuring visibility during traveling, there is an advantage in that it is desired to ensure that air conditioning performance is avoided while avoiding a decrease in heat resistance under specific conditions.
Further, in the air conditioning control as a result based on a rough judgment of only affirmation / denial of restriction execution, an air conditioning control that does not make a detailed judgment on the operating condition of the air conditioner and changes the power distribution based on the detailed judgment. Not done.
The cruising distance can be extended according to the amount of power consumed by the air conditioning, but even if the necessary power for the cruising distance is secured, the air conditioning control may significantly impair comfort. there were.

そこで、この発明の目的は、空調制限下において乗員の快適性をより向上させるように、空調装置の運転条件等の詳細な判断を行うこと、詳細な判断に基づいて電力配分を変更する等で効率的な空調制御を行うこと、それらによって航続距離の確保と乗員の快適性確保とを両立する空調制御装置を提供することにある。   Accordingly, an object of the present invention is to make a detailed determination of the operating conditions of the air conditioner, change the power distribution based on the detailed determination, etc., so as to further improve passenger comfort under air conditioning restrictions. An object of the present invention is to provide an air-conditioning control device that performs efficient air-conditioning control and thereby ensures both a cruising distance and passenger comfort.

A cooling device that is driven by electric power when using the cooling system and a heating device that is driven by electric power when using the heating system of the air conditioner, and at least when the state of charge of the battery is low In the air conditioning control device that restricts the power supplied to the air conditioner, the air conditioning usable power amount is calculated, the usage rate of the cooling device is calculated, and the air conditioning usable power amount and the usage rate of the cooling device are While calculating the usable electric energy, the usage ratio of the heating equipment is calculated, and the air conditioning usable electric energy and the heating equipment usage are calculated.

また、この電動車両用空調制御手段３８においては、自動空調システムの場合に、自動エアコン制御手段３８が算出した目標吹出し温度とＭＯＤＥ（吹出し口）状態から、図３に示す冷房機器の使用割合Ｘを算出する（Ｘは、０〜１００％間で設定を行う）。ここで、ＭＯＤＥは、デフロスタ（ＤＦＲ）、Ｄ（デフロスタ）／Ｆ（フット）時は曇り止めを優先するため、冷房機器３１の使用割合を大きめに設定する。一方、手動空調システムの場合は、ＭＯＤＥ位置、温度調節位置から、図４に示す冷房機器３１の使用割合を算出する（Ｘは、０〜１００％間で設定を行う）。 As shown in FIG. 1, the electric vehicle air conditioning control means 38 includes a power amount calculation unit 38 </ b> A that calculates a target cooling power amount and a target heating power amount, and a state determination unit that determines a temperature adjustment state outlet (MODE) state. 38B, a usage rate calculation unit 38C that calculates the usage rate of the cooling device 31 and the usage rate of the heating device 33, and the available power amount that calculates the available power amount of the cooling device 31 and the available power amount of the heating device 33. And a calculation unit 38D.
The air conditioning control means 38 for the electric vehicle communicates with the electric compressor 32 as the cooling device 31 and the auxiliary heater 34 as the heating device 33, and is calculated from the evaporator thermistor temperature, the water temperature, etc., and is necessary for comfort. The target cooling power amount (the power amount of the electric compressor 32) and the target heating power amount (the power amount of the auxiliary heater (PTC etc.) 34) are calculated.
Further, in the electric vehicle air conditioning control means 38, in the case of an automatic air conditioning system, the usage rate X of the cooling device shown in FIG. 3 is calculated from the target blowout temperature and MODE (blowout port) state calculated by the automatic air conditioning control means 38. (X is set between 0 and 100%). Here, in MODE, since the defroster (DFR) and D (defroster) / F (foot) give priority to anti-fogging, the use ratio of the cooling device 31 is set to be large. On the other hand, in the case of a manual air conditioning system, the usage ratio of the cooling device 31 shown in FIG. 4 is calculated from the MODE position and the temperature adjustment position (X is set between 0 and 100%).

前記暖房機器３３の使用割合は、１００％から前記算出された冷房機器３１の使用割合Ｘ％を引いた値で算出する（暖房機器使用割合＝１００％−Ｘ％）。
また、前記算出された空調使用可能電力量は、変動が大きい入力のため、平均処理を設けて、値の変動を抑制する。制限無しの場合には、空調機器の制限が無いため、以下の処理は、制限有りの場合のみ実施する。
この平均処理にて算出された平均空調使用可能電力量から冷房機器３１の使用割合、暖房機器３３の使用割合を用いて、冷房機器使用可能電力量、暖房機器使用可能電力量を算出する（図５参照）。
そして、前記算出された冷房機器使用可能電力量と前記算出された目標冷房電力量とを比較し、目標冷房電力量＞冷房機器使用可能電力量となる場合には、暖房機器３３へ提供できる冷房機器電力差を零（０）とし、冷房駆動制限値を、冷房機器使用可能電力量＋暖房機器電力差とする（図６参照）。
さらに、この冷房駆動制限値にて、冷房機器３１の駆動を行う。目標冷房電力量よりも冷房機器使用電力量が低い場合には、冷房機器使用可能電力の差分を暖房機器３３側に提供し、冷房駆動制限値を、制限無しと同様に、目標冷房電力量にて冷房機器３１の駆動を行う。この暖房に関しても、冷房機器３１と同様に、暖房駆動制限値を確定させる（図７参照）。 The usage rate of the heating device 33 is calculated by subtracting the calculated usage rate X% of the cooling device 31 from 100% (heating device usage rate = 100% −X%).
Moreover, since the calculated air-conditioning usable electric energy has a large fluctuation, an average process is provided to suppress fluctuations in the value. When there is no restriction, there is no restriction on the air conditioning equipment, so the following processing is performed only when there is a restriction.
From the average air conditioning usable electric energy calculated in this averaging process, the cooling device usable electric energy and the heating device usable electric energy are calculated using the usage ratio of the cooling device 31 and the usage ratio of the heating device 33 (FIG. 5).
Then, the calculated cooling device usable power amount is compared with the calculated target cooling power amount, and when the target cooling power amount> the cooling device usable power amount, the cooling that can be provided to the heating device 33. The equipment power difference is set to zero (0), and the cooling drive limit value is set to the cooling equipment usable power amount + the heating equipment power difference (see FIG. 6).
Further, the cooling device 31 is driven with the cooling drive limit value. When the power consumption of the cooling device is lower than the target cooling power amount, the difference between the cooling device usable power is provided to the heating device 33 side, and the cooling drive limit value is set to the target cooling power amount in the same manner as when there is no limit. Then, the cooling device 31 is driven. With respect to this heating as well, the heating drive limit value is determined similarly to the cooling device 31 (see FIG. 7).

また、冷房機器３１の使用割合を、目標噴出温度又はそれに相当する物理量と噴出口選択モードとに基づいて設定する。この場合、暖房機器３３の使用割合を、全体１、すなわち１００％から冷房機器３１の使用割合を差し引いた差分とする。
