Description
本発明は、ハイブリッド車両の制御装置に関し、特に、エンジン作動の有無に応じたドライバビリティを向上させるための改良に関する。 The present invention relates to a control apparatus for a hybrid vehicle, and more particularly to an improvement for enhancing the drivability in response to the presence or absence of engine operation movement.
ところで、前述したようなハイブリッド車両において、前記エンジンの動力により前記第１電動機で発電すると共に、その第１電動機により発電された電力を用いて専ら前記第２電動機により走行用駆動力を発生させる駆動状態を成立させるものが知られている。この駆動状態においては、前記エンジンは作動しているもののその出力は専ら前記第１電動機による発電に用いられ、走行用駆動力としては用いられない。斯かる駆動状態において、前記従来の技術では、電動機のみで駆動力を発生する駆動状態と同様に、電動機とエンジンの両方で駆動力を発生する駆動状態よりもアクセル操作量に対して出力される駆動力が比較的小さくなるように制御される。しかしながら、運転者の心理としては、エンジンが作動しておりその作動音が聞こえる場合には、電動機のみで駆動力を発生する駆動状態よりもスポーティで加速感ある走行が実現できそうな印象を持ちがちであり、例えばエンジンが始動したのに電動機のみで駆動力を発生する駆動状態と同じ出力特性ではその印象が裏切られ、運転者が満足感を得られないおそれがあった。このため、エンジン作動の有無に応じたドライバビリティを向上させるハイブリッド車両の制御装置の開発が求められていた。 By the way, in the hybrid vehicle as described above, the first electric motor generates electric power with the power of the engine, and the second electric motor generates driving power exclusively by using the electric power generated by the first electric motor. What establishes a state is known . In this driving state, although the engine is operating, its output is exclusively used for power generation by the first electric motor and not used as a driving force for traveling. In such a driving state, in the conventional technique, as in the driving state in which the driving force is generated only by the electric motor, the output is made with respect to the accelerator operation amount than the driving state in which the driving force is generated by both the electric motor and the engine. The driving force is controlled to be relatively small. However, as the psychological OPERATION person, if the operation sound engine is operating is heard, the likely realized traveling with acceleration feeling sporty impression than the drive state for generating a drive force only by an electric motor have often der is, for example, the engine is betrayed its impression in the same output characteristics as the driving state for generating a drive force only by the electric motor to the start, there is a possibility that the driver does not get a sense of satisfaction. Therefore, development of a control apparatus for a hybrid vehicle for improving the drivability in response to the presence or absence of engine operation movement has been demanded.
本発明は、以上の事情を背景として為されたものであり、その目的とするところは、エンジン作動の有無に応じたドライバビリティを向上させるハイブリッド車両の制御装置を提供することにある。 The present invention has been completed with the above view in mind and has an object to provide a control apparatus for a hybrid vehicle for improving the drivability in response to the presence or absence of engine operation movement.
斯かる目的を達成するために、本発明の要旨とするところは、エンジンと、そのエンジンに連結された第１電動機と、車輪に連結された第２電動機と、前記第１電動機及び第２電動機に電力を供給する蓄電装置と、前記エンジンと前記車輪との間の動力伝達経路を断接するクラッチとを、備え、前記エンジンが停止させられると共に、前記蓄電装置から供給される電力を用いて専ら前記第２電動機により走行用駆動力を発生させる第１の駆動状態と、前記クラッチにより前記エンジンと前記車輪との間の動力伝達経路が遮断され、前記エンジンの動力により前記第１電動機で発電すると共に、その第１電動機により発電された電力及び前記蓄電装置から供給される電力の少なくとも一方を用いて専ら前記第２電動機により走行用駆動力を発生させる第２の駆動状態とを、選択的に成立させる形式のハイブリッド車両の制御装置であって、前記第２の駆動状態においては、同じアクセル操作変化量に対して前記第１の駆動状態よりも走行用駆動力の変化が大きいことを特徴とするものである。 In order to achieve such an object, the gist of the present invention includes an engine, a first electric motor coupled to the engine, a second electric motor coupled to wheels, and the first electric motor and the second electric motor. And a clutch for connecting and disconnecting a power transmission path between the engine and the wheels, and the engine is stopped and exclusively used with the power supplied from the power storage device. A first driving state in which a driving force for traveling is generated by the second electric motor, and a power transmission path between the engine and the wheel is interrupted by the clutch, and the first electric motor generates electric power by the power of the engine. And at least one of the electric power generated by the first electric motor and the electric power supplied from the power storage device generates a driving force for traveling by the second electric motor. And a second drive state in which, a control apparatus for a hybrid vehicle of the type to establish selectively, wherein in the second driving state, than the for the same accelerator operation amount of change first driving state This is characterized in that a change in driving force for traveling is large .
このようにすれば、前記エンジンが停止させられると共に、前記蓄電装置から供給される電力を用いて専ら前記第２電動機により走行用駆動力を発生させる第１の駆動状態と、前記クラッチにより前記エンジンと前記車輪との間の動力伝達経路が遮断され、前記エンジンの動力により前記第１電動機で発電すると共に、その第１電動機により発電された電力及び前記蓄電装置から供給される電力の少なくとも一方を用いて専ら前記第２電動機により走行用駆動力を発生させる第２の駆動状態とを、選択的に成立させる形式のハイブリッド車両の制御装置であって、前記第２の駆動状態においては、同じアクセル操作変化量に対して前記第１の駆動状態よりも走行用駆動力の変化が大きいことから、専ら電動機により走行用駆動力を発生させる駆動状態であってもエンジンが作動している場合には電動機のみで駆動力を発生する駆動状態よりも同じアクセル操作変化量に対する駆動力の変化が大きい出力特性とすることで、エンジンの作動音等から運転者が抱く印象通りの走行を実現することができる。すなわち、エンジン作動の有無に応じたドライバビリティを向上させるハイブリッド車両の制御装置を提供することができる。 In this case, the engine is stopped, and the engine is driven by the first driving state in which the driving force for driving is generated exclusively by the second electric motor using the electric power supplied from the power storage device. The power transmission path between the motor and the wheel is cut off, and the first motor generates power with the power of the engine, and at least one of the power generated by the first motor and the power supplied from the power storage device A control apparatus for a hybrid vehicle that selectively establishes a second driving state in which the second electric motor generates a driving force for traveling exclusively by the second electric motor , and the same accelerator is used in the second driving state. since a large change in traveling drive force than the first driving state to the operation change amount, to generate a traveling drive force exclusively by electric motor Even dynamic state by the output characteristic variation of the driving force is large for the same accelerator operation amount of change than the drive state for generating a drive force only by the electric motor if the engine is running, the engine operating noise From the above, it is possible to realize the driving as the driver has in mind. That is, it is possible to provide a control apparatus for a hybrid vehicle for improving the drivability in response to the presence or absence of engine operation movement.
ここで、好適には、前記第１の駆動状態及び第２の駆動状態に加えて、前記エンジンにより走行用駆動力を発生させると共に、前記蓄電装置から供給される電力を用いて前記第１電動機により走行用駆動力を発生させる第３の駆動状態を選択的に成立させると共に、その第３の駆動状態においては、同じアクセル操作変化量に対して前記第２の駆動状態と走行用駆動力の変化が等しいものである。このようにすれば、前記エンジン及び第１電動機により走行用駆動力を発生させる駆動状態においては、前記第２電動機のみで駆動力を発生する駆動状態よりも同じアクセル操作変化量に対する駆動力の変化が大きい出力特性とすることで、エンジンの作動音等から運転者が抱く印象通りの走行を実現することができる。また、好適には、前記第１の駆動状態及び第２の駆動状態に加えて、前記エンジンにより走行用駆動力を発生させると共に、前記蓄電装置から供給される電力を用いて前記第１電動機により走行用駆動力を発生させる第３の駆動状態を選択的に成立させると共に、その第３の駆動状態においては、同じアクセル操作変化量に対して前記第２の駆動状態よりも走行用駆動力の変化が大きいものである。このようにすれば、前記エンジン及び第１電動機により走行用駆動力を発生させる駆動状態においては、前記第２電動機のみで駆動力を発生する駆動状態よりも同じアクセル操作変化量に対する駆動力の変化が大きく、専ら発電用に前記エンジンを作動させる駆動状態よりも更に同じアクセル操作変化量に対する駆動力の変化が大きい出力特性とすることで、エンジンの作動音等から運転者が抱く印象通りの走行を実現することができる。また、好適には、運転者による操作に応じてエコモード、ノーマルモード、及びスポーツモードの何れかを選択的に成立させると共に、前記ノーマルモードにおいては、同じアクセル操作変化量に対して前記エコモードよりも走行用駆動力の変化が大きく、且つ前記スポーツモードにおいては、同じアクセル操作変化量に対して前記ノーマルモードよりも走行用駆動力の変化が大きいものである。このようにすれば、運転者による操作に応じて設定される各走行モードにおいて個別に走行用駆動力の出力特性を設定でき、更には各走行モードそれぞれにおいて専ら電動機により走行用駆動力を発生させる駆動状態であってもエンジンが作動している場合には電動機のみで駆動力を発生する駆動状態よりも同じアクセル操作変化量に対する駆動力の変化が大きい出力特性とすることで、運転者が意図する走行を更にきめ細かに実現することができる。 Here, preferably, in addition to the first driving state and the second driving state, the first electric motor is generated by using the engine to generate driving force for traveling and using electric power supplied from the power storage device. In this third driving state, the second driving state and the driving force of the driving force are the same for the same amount of change in accelerator operation. The changes are equal. In this way, in the driving state in which the driving force for traveling is generated by the engine and the first electric motor, the change in the driving force with respect to the same accelerator operation change amount than in the driving state in which the driving force is generated only by the second electric motor. By having a large output characteristic, it is possible to realize traveling as the driver feels from the operating sound of the engine. Preferably, in addition to the first driving state and the second driving state, the engine generates a driving force for traveling, and the first electric motor uses electric power supplied from the power storage device. The third driving state for generating the driving force for traveling is selectively established, and in the third driving state, the driving force for driving is larger than that in the second driving state for the same accelerator operation change amount. The change is big. In this way, in the driving state in which the driving force for traveling is generated by the engine and the first electric motor, the change in the driving force with respect to the same accelerator operation change amount than in the driving state in which the driving force is generated only by the second electric motor. The driving characteristics are large and the driving characteristics change more greatly than the driving state where the engine is operated exclusively for power generation. Can be realized. Preferably, any one of the eco mode, the normal mode, and the sport mode is selectively established according to an operation by the driver, and in the normal mode, the eco mode is applied to the same accelerator operation change amount. large changes in the traveling drive force than, and in the sport mode, the those changes of the running driving force than the normal mode is greater for the same accelerator operation amount of change. In this way, the output characteristics of the driving force for driving can be set individually in each driving mode set according to the operation by the driver, and furthermore , the driving force for driving is generated exclusively by the electric motor in each driving mode . When the engine is operating even in the driving state, the driver intends to have an output characteristic in which the driving force changes with the same amount of change in the accelerator operation than in the driving state where the driving force is generated only by the electric motor. It is possible to achieve a more detailed traveling.
また、好適には、運転者による操作に応じて前記エコモード、ノーマルモード、及びスポーツモードの切り替えが行われた場合には、アクセル操作量が既定値以下となることを条件に同じアクセル操作変化量に対する出力特性の変更を行うものである。このようにすれば、運転者によりモードを切り替えるための操作が行われた直後に走行用駆動力の出力特性が変化することにより却ってドライバビリティが低下するのを好適に抑制することができる。 Preferably, when the eco mode, the normal mode, and the sport mode are switched according to the operation by the driver, the same accelerator operation change is performed on condition that the accelerator operation amount is equal to or less than a predetermined value. The output characteristic is changed with respect to the quantity. If it does in this way, it can control suitably that a drivability falls on the contrary because the output characteristic of driving force for driving changes immediately after operation for switching modes by a driver is performed.
