Description

この発明は車両用空調制御装置に係り、特に、自車両の走行状態に適した走行性能を得るとともに空調機能を向上させて車室内の快適性を向上することができる車両用空調制御装置に関する。 The present invention relates to a vehicle air-conditioning control device, and more particularly to a vehicle air-conditioning control device capable of obtaining a traveling performance suitable for the traveling state of the host vehicle and improving an air-conditioning function to improve comfort in a vehicle compartment.

車両用空調制御装置においては、エンジンを駆動源として駆動される空調装置のコンプレッサを備え、車両の走行状態によってコンプレッサの駆動制御を行うことで、走行状態に適した走行性能を確保できるように空調機能を制御している。
例えば、特開平４−１０９０４０号公報には、エンジンを駆動源として駆動されるコンプレッサの作動を加速走行時に制限し、加速性能を得るようにした制御装置において、自車両の情報を使用して自車両の走行状態を判定し、自車両が加速性能の優先度を下げることが可能な渋滞走行状態にあるときはコンプレッサの作動制限を解除し、空調性能を優先させて冷房性能の低下防止を図った技術が開示されている。 The vehicle air-conditioning control device includes an air-conditioning device compressor driven by an engine as a drive source, and performs air-conditioning so as to ensure driving performance suitable for the driving state by controlling the driving of the compressor according to the driving state of the vehicle. The function is controlled.
For example, Japanese Patent Laid-Open No. 4-109040 discloses that a control device that restricts the operation of a compressor driven with an engine as a driving source during acceleration travel and obtains acceleration performance, uses the information of the own vehicle. When the vehicle is in a traffic jam where the priority of acceleration performance can be lowered, the compressor operation restriction is released and air conditioning performance is prioritized to prevent cooling performance from being lowered. Disclosed techniques.

特開平４−１０９０４０号公報JP-A-4-109040

前記特許文献１に開示される制御装置は、自車両の走行状態をもとに空調装置のコンプレッサの駆動制御を行っている。しかし、前記特許文献１に開示される制御装置は、自車両のみの情報でコンプレッサの駆動制御を行っていたため、自車両の走行状態判定結果に基づく走行性能と空調性能が、走行状態によって実際に必要とされる走行性能と空調性能に不―致が生じていた。
例えば、先行車両が自車両のすぐ前方を走行しているような状況では、加速性能の優先度を下げることが可能であることから、コンプレッサを作動して空調性能を優先することが可能である。つまり、先行車両の状態によって、自車両の走行状態に対する要求は変化する。前記特許文献１は、自車両の情報のみによりコンプレッサを駆動制御していたため、走行状態によって実際に必要とされる走行性能と空調性能に不一致が生じる問題があった。 The control device disclosed in Patent Document 1 performs drive control of the compressor of the air conditioner based on the traveling state of the host vehicle. However, since the control device disclosed in Patent Document 1 performs drive control of the compressor based on information only about the host vehicle, the running performance and the air conditioning performance based on the running state determination result of the own vehicle are actually depending on the running state. There was a mismatch between the required driving performance and air conditioning performance.
For example, in a situation where the preceding vehicle is traveling just in front of the host vehicle, the priority of the acceleration performance can be lowered, so that the air conditioning performance can be prioritized by operating the compressor. . That is, the request for the traveling state of the host vehicle changes depending on the state of the preceding vehicle. In Patent Document 1, since the compressor is driven and controlled only by the information of the own vehicle, there is a problem in that there is a discrepancy between the actually required traveling performance and the air conditioning performance depending on the traveling state.

また、近年は、先行車両の情報により制御を行う装置として、センサにより先行車両の情報（例えば、車間距離、相対速度など）を取得し、緊急時にブレーキを作動させて先行車両との衝突被害を軽減する衝突被害軽減ブレーキ装置が普及している。車両は、エンジンや空調装置などの各種の制御装置を搭載しており、前記衝突被害軽減ブレーキ装置が取得した先行車両の情報を他の制御装置に有効に利用することが考えられる。
例えば、車両において先行車両の情報を取得する装置を搭載している場合、前記特許文献１のように自車両の情報のみによるコンプレッサの駆動制御でなく、自車両の情報に衝突被害軽減ブレーキ装置が取得した先行車両の情報を合わせてコンプレッサの駆動制御を行うことで、前記走行状態によって実際に必要とされる走行性能と空調性能の不一致を解消しつつ、必要とされるブレーキ性能、走行性能と空調性能を実現することができる。 Further, in recent years, as a device that performs control based on information on the preceding vehicle, information on the preceding vehicle (for example, inter-vehicle distance, relative speed, etc.) is acquired by a sensor, and a brake is operated in an emergency to cause collision damage with the preceding vehicle. Collision mitigation brake devices to reduce are widespread. The vehicle is equipped with various control devices such as an engine and an air conditioner, and it is conceivable to effectively use the information on the preceding vehicle acquired by the collision damage reducing brake device for other control devices.
For example, when a device for acquiring information on a preceding vehicle is installed in a vehicle, a collision damage reducing brake device is not included in the information on the own vehicle, but on the information on the own vehicle, instead of the compressor drive control based only on the information on the own vehicle as in Patent Document 1. By combining the acquired information on the preceding vehicle and controlling the drive of the compressor, the discrepancy between the actually required driving performance and the air conditioning performance depending on the driving state is solved, and the required braking performance and driving performance are Air conditioning performance can be realized.

この発明は、自車両の走行状態に適した走行性能を得ることができるとともに、空調機能を向上させて車室内の快適性を向上することができる車両用空調制御装置を実現することを目的とする。 An object of the present invention is to realize a vehicle air conditioning control device that can obtain a traveling performance suitable for the traveling state of the host vehicle and can improve the comfort of the passenger compartment by improving the air conditioning function. To do.

この発明は、エンジンを駆動源として駆動されるコンプレッサを備えた車両用空調制御装置において、先行車両の有無を検出する先行車両検出部と自車両の走行状態を判定する走行状態判定部とを設け、前記先行車両検出部で検出された先行車情報と前記走行状態判定部で判定された走行状態とに基づいて前記コンプレッサの駆動を制御するコンプレッサ制御部を備えることを特徴としている。 The present invention provides a vehicle air-conditioning control apparatus including a compressor driven using an engine as a drive source, and includes a preceding vehicle detection unit that detects the presence or absence of a preceding vehicle and a traveling state determination unit that determines the traveling state of the host vehicle. And a compressor control unit that controls driving of the compressor based on the preceding vehicle information detected by the preceding vehicle detection unit and the traveling state determined by the traveling state determination unit.

この発明は、自車両の情報と先行車両の情報とでコンプレッサの駆動制御を行うことにより、走行状態によって実際に必要とされる走行性能と空調性能を実現することができ、自車両の走行状態に適した走行性能を得ることができるとともに、空調機能を向上させて車室内の快適性を向上することができる。 In the present invention, by controlling the drive of the compressor based on the information on the own vehicle and the information on the preceding vehicle, it is possible to realize the traveling performance and the air conditioning performance that are actually required depending on the traveling state. Driving performance suitable for the vehicle can be obtained, and the air conditioning function can be improved to improve the comfort in the passenger compartment.

以下、図面に基づいて、この発明の実施例を説明する。 Embodiments of the present invention will be described below with reference to the drawings.

図１〜図３は、この発明の実施例を示すものである。図１において、自車両に搭載されたエンジン１を駆動源として駆動される空調用のコンプレッサ２は、車両用空調制御装置３の空調制御手段４によって制御される。車両用空調制御装置３は、空調制御手段４に走行状態判定部５とコンプレッサ制御部６とを備えている。空調制御手段４には、アクセルセンサ７とエンジン制御手段８と先行車両検出部９とが接続され、自車両の情報及び自車両の前方を走行する先行車両の情報が入力される。
前記アクセルセンサ７は、アクセルペダルの踏込み状態を検出し、アクセル開度情報を出力する。前記エンジン制御手段８は、エンジン１を制御するために取得した、自車両の車速情報とブレーキペダルのブレーキ操作情報とエンジン１のエンジン回転数情報とを出力する。前記先行車両検出部９は、レーダやカメラなどで先行車両の有り無し・車速などを検出し、先行車両情報を出力する。なお、先行車両検出部９は、車両に衝突被害軽減ブレーキ装置が搭載されている場合、衝突被害軽減ブレーキ装置が取得した先行車両の情報を利用して、先行車両の有り無し・車速を検出することができる。
前記先行車両検出部９は、少なくとも先行車両の有無と、先行車両と自車両との車間距離とを検出し、先行車両有りと検出された場合でも、先行車両との車間距離が予め設定された距離よりも大きい場合は先行車両無しとする。また、先行車両検出部９は、少なくとも先行車両の有無と、先行車両と自車両との相対速度とを検出し、先行車両有りと検出された場合でも、先行車両との相対速度が大きい場合は先行車両無しとする。
前記走行状態判定部５は、アクセルセンサ７から入力するアクセル開度情報と、エンジン制御手段８から入力する自車両の車速情報とブレーキ操作情報とエンジン回転数情報とから、自車両の走行状態を、例えば図２に示すように、停車状態、加速状態、一定速走行状態、減速状態、の４通りに分けて判定する。 1 to 3 show an embodiment of the present invention. In FIG. 1, an air conditioning compressor 2 driven using an engine 1 mounted on the host vehicle as a drive source is controlled by an air conditioning control means 4 of a vehicle air conditioning control device 3. The vehicle air conditioning control device 3 includes a traveling state determination unit 5 and a compressor control unit 6 in the air conditioning control means 4. The air-conditioning control means 4 is connected to the accelerator sensor 7, the engine control means 8, and the preceding vehicle detection unit 9, and receives information on the own vehicle and information on the preceding vehicle traveling in front of the own vehicle.
The accelerator sensor 7 detects the depression state of the accelerator pedal and outputs accelerator opening information. The engine control means 8 outputs the vehicle speed information of the host vehicle, the brake operation information of the brake pedal, and the engine speed information of the engine 1 acquired for controlling the engine 1. The preceding vehicle detection unit 9 detects the presence / absence / speed of the preceding vehicle using a radar or a camera, and outputs preceding vehicle information. In addition, when the collision damage reduction brake device is mounted on the vehicle, the preceding vehicle detection unit 9 detects the presence / absence / speed of the preceding vehicle using the information on the preceding vehicle acquired by the collision damage reduction brake device. be able to.
The preceding vehicle detection unit 9 detects at least the presence or absence of a preceding vehicle and the inter-vehicle distance between the preceding vehicle and the host vehicle, and the inter-vehicle distance from the preceding vehicle is set in advance even when the presence of the preceding vehicle is detected. If it is larger than the distance, there is no preceding vehicle. Further, the preceding vehicle detection unit 9 detects at least the presence or absence of the preceding vehicle and the relative speed between the preceding vehicle and the host vehicle. Even when the presence of the preceding vehicle is detected, if the relative speed with the preceding vehicle is large, There is no preceding vehicle.
The traveling state determination unit 5 determines the traveling state of the host vehicle from the accelerator opening information input from the accelerator sensor 7, the vehicle speed information, the brake operation information, and the engine speed information input from the engine control unit 8. For example, as shown in FIG. 2, the determination is made in four ways: a stop state, an acceleration state, a constant speed traveling state, and a deceleration state.

前記コンプレッサ制御部６は、先行車両検出部９で検出された先行車両情報と走行状態判定部５により判定された自車両の走行状態とに基づいてコンプレッサ２の駆動を制御し、コンプレッサ２の負荷を増加または減少させる。コンプレッサ制御部６は、４通りに分けた自車両の停車状態、加速状態、一定速走行状態、減速状態について、それぞれ先行車両が有りの場合、無しの場合に応じて走行性能、空調性能の優先順位を以下のように設定している（図２参照）。 The compressor control unit 6 controls the driving of the compressor 2 based on the preceding vehicle information detected by the preceding vehicle detection unit 9 and the traveling state of the host vehicle determined by the traveling state determination unit 5, and the load on the compressor 2 Increase or decrease. The compressor control unit 6 gives priority to the running performance and air conditioning performance according to the case where the preceding vehicle is present and the absence, respectively, with respect to the stopping state, the acceleration state, the constant speed traveling state, and the deceleration state of the own vehicle divided into four types. The ranking is set as follows (see FIG. 2).

・停車状態においては、先行車両が有り場合は空調性能優先、先行車両無しの場合は走行性能（加速性能）優先とする。
・加速状態においては、先行車両が有り場合は空調性能優先、先行車両無しの場合は走行性能（加速性能）優先とする。
・一定速走行状態においては、先行車両が有り場合はブレーキ性能優先、先行車両無しの場合は空調性能優先とする。
・減速状態においては、先行車両が有り場合はブレーキ性能優先、先行車両無しの場合はブレーキ性能優先とする。 -When the vehicle is stopped, priority is given to air-conditioning performance when there is a preceding vehicle, and priority is given to running performance (acceleration performance) when there is no preceding vehicle.
-In the acceleration state, priority is given to air conditioning performance when there is a preceding vehicle, and priority is given to running performance (acceleration performance) when there is no preceding vehicle.
・ In a constant speed driving state, priority is given to brake performance when there is a preceding vehicle, and priority is given to air conditioning performance when there is no preceding vehicle.
・ In the deceleration state, priority is given to brake performance when there is a preceding vehicle, and priority is given to brake performance when there is no preceding vehicle.

前記コンプレッサ制御部６は、走行性能、空調機能の優先順位の設定を参照し、先行車両情報と走行状態とに基づいてコンプレッサ２の負荷を切り換えることで、ブレーキ性能、走行性能を妨げることがないよう、空調機能を調節する。 The compressor control unit 6 refers to the setting of the priority of the running performance and the air conditioning function, and does not disturb the braking performance and the running performance by switching the load of the compressor 2 based on the preceding vehicle information and the running state. Adjust the air conditioning function.

これにより、車両用空調制御装置３は、走行状態判定部５で少なくとも停車状態を判定し、コンプレッサ制御部６によって、先行車両検出部９で先行車両有りを検出し、走行状態判定部５により停車状態と判定された場合に、空調性能を優先してコンプレッサ２の負荷を増加させる。
また、車両用空調制御装置３は、走行状態判定部５で少なくとも加速状態を判定し、コンプレッサ制御部６によって、先行車両検出部９で先行車両有りを検出し、走行状態判定部５により加速状態と判定された場合に、空調性能を優先してコンプレッサ２の負荷を増加させる。
さらに、車両用空調制御装置３は、走行状態判定部５で少なくとも一定速走行状態を判定し、コンプレッサ制御部６によって、先行車両検出部９で先行車両有りを検出し、走行状態判定部５により一定速走行状態と判定された場合に、ブレーキ性能を優先してコンプレッサ２の負荷を減少させる。 As a result, the vehicle air-conditioning control device 3 determines at least the stop state by the traveling state determination unit 5, detects the presence of the preceding vehicle by the preceding vehicle detection unit 9 by the compressor control unit 6, and stops by the traveling state determination unit 5. When the state is determined, the load on the compressor 2 is increased by giving priority to the air conditioning performance.
The vehicle air-conditioning control device 3 determines at least the acceleration state by the traveling state determination unit 5, detects the presence of the preceding vehicle by the preceding vehicle detection unit 9 by the compressor control unit 6, and accelerates by the traveling state determination unit 5. When it is determined that the air conditioning performance is prioritized, the load on the compressor 2 is increased.
Further, the vehicle air-conditioning control device 3 determines at least a constant speed traveling state by the traveling state determination unit 5, detects the presence of the preceding vehicle by the preceding vehicle detection unit 9 by the compressor control unit 6, and detects the presence of the preceding vehicle by the traveling state determination unit 5. When it is determined that the vehicle is traveling at a constant speed, the load on the compressor 2 is reduced by giving priority to the brake performance.

次に作用を説明する。
車両用空調制御装置３は、図３に示すように、空調制御のプログラムがスタートすると（Ｓ０１）、走行状態判定部５により自車両の走行状態を判定し（Ｓ０２）、先行車両検出部９で検出された先行車両情報に基づいて、先行車両が有るかを判断する（Ｓ０３）。
この判断（Ｓ０３）がＮＯ（先行車両が無し）場合は、車両用空調制御装置３は何もせず、プログラムをエンドにする（Ｓ０６）。この判断（Ｓ０３）がＹＥＳ（先行車両が有り場合は、自車両が停車状態または加速状態かを判断する（Ｓ０４）。
この判断（Ｓ０４）がＹＥＳの場合は、コンプレッサ２の負荷を増加させ、プログラムをエンドにする（Ｓ０６）。この判断（Ｓ０４）がＮＯの場合は、自車両が一定速走行状態であるかを判断する（Ｓ０７）。
この判断（Ｓ０７）がＹＥＳの場合は、コンプレッサ２の負荷を減少させ、プログラムをエンドにする（Ｓ０６）。この判断（Ｓ０７）がＮＯの場合は、車両用空調制御装置３は何もせず、プログラムをエンドにする（Ｓ０６）。 Next, the operation will be described.
As shown in FIG. 3, when the air conditioning control program starts (S 01), the vehicle air conditioning control device 3 determines the traveling state of the host vehicle by the traveling state determination unit 5 (S 02), and the preceding vehicle detection unit 9 Based on the detected preceding vehicle information, it is determined whether there is a preceding vehicle (S03).
If this determination (S03) is NO (no preceding vehicle), the vehicle air-conditioning control device 3 does nothing and ends the program (S06). This determination (S03) is YES (when there is a preceding vehicle, it is determined whether the host vehicle is in a stopped state or an accelerated state (S04).
If this determination (S04) is YES, the load on the compressor 2 is increased and the program is ended (S06). If this determination (S04) is NO, it is determined whether the host vehicle is traveling at a constant speed (S07).
If this determination (S07) is YES, the load on the compressor 2 is reduced and the program is ended (S06). If this determination (S07) is NO, the vehicle air-conditioning control device 3 does nothing and ends the program (S06).

このように、車両用空調制御装置３は、先行車両検出部９で検出された先行車情報と走行状態判定部５で判定された走行状態とに基づいてコンプレッサ２の駆動を制御することで、走行状態によって実際に必要とされる走行性能と空調性能を実現することができ、自車両の走行状態に適した走行性能を得ることができるとともに、空調機能を向上させて車室内の快適性を向上することができる。
先行車両が有る場合には、自車両の発進時の加速において、自車両の加速は先行車両の存在によって制限される。この車両用空調制御装置３は、先行車両検出部９で先行車両有りを検出し、走行状態判定部５により停車状態と判定された場合に、コンプレッサ２の負荷を増加させるため、停車状態の空調性能を向上することができる。
先行車両がある場合には、自車両の走行時の加速において、自車両の加速は先行車両の存在によって制限される。この車両用空調制御装置３は、先行車両検出部９で先行車両有りを検出し、走行状態判定部５により加速状態と判定された場合に、コンプレッサ２の負荷を増加させるため、自車両の加速性能を抑え、先行車両との車間距離を確保して衝突の可能性を下げるとともに、加速状態の空調性能を向上させることができる。
また、車両用空調制御装置３は、先行車両検出部９で先行車両有りを検出し、走行状態判定部５により一定速走行状態と判定された場合に、コンプレッサ２の負荷を減少させるため、自車両のブレーキ性能の低下を抑え、先行車両との衝突の可能性を下げることができる。 Thus, the vehicle air-conditioning control device 3 controls the drive of the compressor 2 based on the preceding vehicle information detected by the preceding vehicle detection unit 9 and the traveling state determined by the traveling state determination unit 5. It can achieve the driving performance and air conditioning performance that are actually required depending on the driving conditions, and can obtain the driving performance suitable for the driving condition of the host vehicle, and improve the air conditioning function to improve the comfort in the passenger compartment. Can be improved.
When there is a preceding vehicle, the acceleration of the own vehicle is limited by the presence of the preceding vehicle in the acceleration at the start of the own vehicle. The vehicle air-conditioning control device 3 detects the presence of a preceding vehicle by the preceding vehicle detection unit 9 and increases the load on the compressor 2 when the traveling state determination unit 5 determines that the vehicle is stopped. The performance can be improved.
When there is a preceding vehicle, the acceleration of the own vehicle is limited by the presence of the preceding vehicle in the acceleration when the own vehicle is traveling. This vehicle air-conditioning control device 3 detects the presence of a preceding vehicle by the preceding vehicle detection unit 9 and increases the load on the compressor 2 when the traveling state determination unit 5 determines that the vehicle is in an acceleration state. The performance can be suppressed, the distance from the preceding vehicle can be secured to reduce the possibility of a collision, and the air conditioning performance in the accelerated state can be improved.
The vehicle air-conditioning control device 3 detects the presence of the preceding vehicle by the preceding vehicle detection unit 9 and reduces the load on the compressor 2 when the traveling state determination unit 5 determines that the vehicle is traveling at a constant speed. A decrease in the braking performance of the vehicle can be suppressed, and the possibility of a collision with the preceding vehicle can be reduced.

さらに、先行車両検出部９は、少なくとも先行車両の有無と、先行車両との車間距離とを検出し、先行車両有りと検出された場合でも、先行車両との車間距離が予め設定された距離よりも大きい場合は先行車両無しとする。また、先行車両検出部９は、少なくとも先行車両の有無と、先行車両との相対速度とを検出し、先行車両有りと検出された場合でも、先行車両との相対速度が大きい場合は先行車両無しとする。
これにより、車両用空調制御装置３は、先行車両の有無だけではなく、自車両と先行車両との車間距離が大きく離れている場合、または自車両に対して先行車両が遠ざかる方向に相対速度が大きい場合は先行車両無しとするため、状況に応じたコンプレッサ２の駆動制御を行うことができる。
なお、車両用空調制御装置３は、自車両の情報と先行車両の情報とを元にコンプレッサ２の負荷を調節したが、コンプレッサ２の調節をＯＮ／ＯＦＦといった単純なものではなく、外部可変コンプレッサのようにより細かく制御できる場合においても、先行車両の有無によって、コンプレッサの駆動状態を変化させ、空調性能を最適化することができる。 Furthermore, the preceding vehicle detection unit 9 detects at least the presence or absence of the preceding vehicle and the inter-vehicle distance from the preceding vehicle. Even when the presence of the preceding vehicle is detected, the inter-vehicle distance from the preceding vehicle is determined based on the preset distance. Is too large, there is no preceding vehicle. Further, the preceding vehicle detection unit 9 detects at least the presence or absence of the preceding vehicle and the relative speed with the preceding vehicle. Even when the presence of the preceding vehicle is detected, there is no preceding vehicle when the relative speed with the preceding vehicle is large. And
Thereby, the vehicle air-conditioning control device 3 has not only the presence or absence of the preceding vehicle, but also the relative speed in the direction in which the preceding vehicle moves away from the own vehicle when the distance between the own vehicle and the preceding vehicle is greatly separated. If it is larger, there is no preceding vehicle, so that the drive control of the compressor 2 according to the situation can be performed.
Although the vehicle air-conditioning control device 3 adjusts the load of the compressor 2 based on the information on the own vehicle and the information on the preceding vehicle, the adjustment of the compressor 2 is not a simple one such as ON / OFF. Even when the control can be performed more finely as described above, the driving state of the compressor can be changed depending on the presence or absence of the preceding vehicle, and the air conditioning performance can be optimized.

この発明は、自車両の情報と先行車両の情報とでコンプレッサを駆動制御することで、走行性能を妨げないように空調機能を調節することができるものであり、エンジンにより駆動される空調用のコンプレッサを搭載したあらゆる車両に適用することが可能である。 In the present invention, the compressor is driven and controlled by the information on the host vehicle and the information on the preceding vehicle, so that the air conditioning function can be adjusted so as not to hinder the running performance. It can be applied to any vehicle equipped with a compressor.
