Description
ここで、請求項1にかかる発明の要旨とするところは、エンジンの出力を駆動輪へ伝達する車両用駆動装置の制御装置であって、(a) 前記エンジンに連結された第1要素と第1電動機に連結された第2要素と第2電動機および伝達部材に連結された第3要素とを有するとともにその第1要素乃至第3要素のうちのいずれか2つを相互にまたはその第2要素を非回転部材に連結する係合装置を有する動力分配機構を備え、電気的な無段変速機として作動可能な無段変速状態と有段の変速機として作動可能な有段変速状態とに切り換え可能な変速状態切換型変速機構と、(b) 車両の所定条件に基づいて前記係合装置の解放と係合とを切換制御することで前記変速状態切換型変速機構を前記無段変速状態と前記有段変速状態とのいずれかに選択的に切り換える切換制御手段と、(c) 前記係合装置の係合に際して前記第1要素、第2要素、および第3要素の相互の回転速度差或いは前記第2要素と前記非回転部材との回転速度差を抑制するように前記第1電動機による回転同期制御を行う電動機制御手段とを、含み、(d) 前記切換制御手段による前記変速状態切換型変速機構の前記無段変速状態から有段変速状態への切換制御において、その有段変速状態への切換えが実行される場合には、前記電動機制御手段による回転同期制御中であって、前記係合装置の係合圧を係合完了後の係合圧に向かって上昇させる前に所定の係合圧にて低圧待機させることにある。
このようにすれば、エンジンに連結された第1要素と第1電動機に連結された第2要素と第2電動機および伝達部材に連結された第3要素とを有するとともにその第1要素乃至第3要素のうちのいずれか2つを相互にまたはその第2要素を非回転部材に連結する係合装置を有する動力分配機構を備え、電気的な無段変速機として作動可能な無段変速状態と有段の変速機として作動可能な有段変速状態とに切り換え可能な変速状態切換型変速機構における、切換制御手段による前記係合装置の係合に際して3つの要素の相互の回転速度差或いは第2要素と非回転部材との回転速度差を抑制するように前記第1電動機による回転同期制御が行われるので、回転要素の回転速度が有段変速状態とされるときの回転速度に向かって制御されて係合装置の係合による回転速度差の回転同期に伴う切換ショックが抑制され、また係合装置の半係合状態での係合装置自体の回転速度差が抑制されることでその係合装置の仕事量が抑制されて係合装置の耐久性が向上する。また、3つの要素と係合装置により動力分配機構が簡単に構成されるとともに、切換制御手段により係合装置が制御されることにより変速状態切換型変速機構が無段変速状態と有段変速状態とに簡単に切り換えられる。また、前記変速状態切換型変速機構の前記無段変速状態から有段変速状態への切換えが実行される場合には、前記電動機制御手段による回転同期制御中であって、前記係合装置の係合圧が係合完了後の係合圧に向かって上昇させられる前に所定の係合圧にて低圧待機させられるので、係合装置の係合圧を係合完了後の係合圧に向かって上昇させる際に、より早く係合装置にトルク容量を持たせることができる。また、その分だけ係合装置がより早く係合完了させられる。これにより、例えば、前記係合装置の係合に際して電動機の電動機制御と係合装置の係合制御とが重なって実行される所謂オーバーラップ制御が行われる場合にはそのオーバーラップ制御がより早く実行される。
また、請求項2にかかる発明の要旨とするところは、エンジンの出力を第1電動機および伝達部材へ分配するとともに複数の回転要素を有する差動機構を有して電気的な差動装置として作動可能な差動部を備えた車両用駆動装置の制御装置であって、(a) 駆動輪に動力伝達可能とされた第2電動機と、(b) 前記差動機構に備えられ、前記差動部を電気的な差動装置として作動可能な差動作用が働く差動状態とその差動作用をしないロック状態とに切り換えるための係合装置と、(c) 車両の所定条件に基づいて前記係合装置の解放と係合とを切換制御することで前記差動部を前記差動状態と前記ロック状態とのいずれかに選択的に切り換える切換制御手段と、(d) その切換制御手段による前記係合装置の係合に際して前記複数の回転要素の相互の回転速度差或いはその第1電動機が連結されるその回転要素と非回転部材との回転速度差を抑制するようにその第1電動機による回転同期制御を行う電動機制御手段とを、含み、(e) 前記切換制御手段による前記差動部の前記差動状態からロック状態への切換制御において、そのロック状態への切換えが実行される場合には、前記電動機制御手段による回転同期制御中であって、前記係合装置の係合圧を係合完了後の係合圧に向かって上昇させる前に所定の係合圧にて低圧待機させることにある。
このようにすれば、前記差動部を電気的な差動装置として作動可能な差動作用が働く差動状態とその差動作用をしないロック状態とに切り換えるための前記係合装置が備えられることで、切換制御手段により車両の所定条件に基づいてその係合装置の解放と係合とが切換制御されて前記差動部が前記差動状態と前記ロック状態とのいずれかに選択的に切り換えられる。また、前記差動状態と前記ロック状態とに切換え可能に構成される差動部を備えた駆動装置において、その切換制御手段による前記係合装置の係合に際して前記複数の回転要素の相互の回転速度差或いはその第1電動機が連結されるその回転要素と非回転部材との回転速度差を抑制するようにその第1電動機による回転同期制御が行われるので、前記係合装置の係合時には複数の回転要素の回転速度が係合完了後の回転速度すなわちロック状態とされるときの回転速度に向かって回転制御されて係合装置の係合による回転速度差の回転同期に伴う切換ショックが抑制され、また係合装置の半係合状態での係合装置自体の回転速度差が抑制されることでその係合装置の仕事量が抑制されて係合装置の耐久性が向上する。また、前記差動部の前記差動状態からロック状態への切換えが実行される場合には、前記電動機制御手段による回転同期制御中であって、前記係合装置の係合圧が係合完了後の係合圧に向かって上昇させられる前に所定の係合圧にて低圧待機させられるので、係合装置の係合圧を係合完了後の係合圧に向かって上昇させる際に、より早く係合装置にトルク容量を持たせることができる。また、その分だけ係合装置がより早く係合完了させられる。これにより、例えば、前記係合装置の係合に際して電動機の電動機制御と係合装置の係合制御とが重なって実行される所謂オーバーラップ制御が行われる場合にはそのオーバーラップ制御がより早く実行される。
