Description
また、上記目的を達成するための、請求項2に係る発明の要旨とするところは、(a)駆動源の出力を第1電動機および伝達部材へ分配する電気式差動部と、前記駆動源の出力軸から駆動輪までの動力伝達経路に連結された第2電動機と、前記電気式差動部に備えられて該電気式差動部を差動状態と非差動状態とに選択的に切換えるための係合装置と、前記第1または第2電動機から供給された電力を充放電可能な蓄電器とを、含む車両用動力伝達装置の制御装置において、(b)前記電気式差動部の所定の部材から入力されたトルクの反力トルクを前記第1電動機および前記係合装置により受け止めることが可能とされ、前記反力トルクの前記第1電動機と前記係合装置との分担割合を、前記第1電動機による発電量からの前記第2電動機による放電量の差分値が大きい程、前記係合装置の分担割合を増加させるトルク分担率制御手段を備え、(c)前記トルク分担率制御手段は、前記蓄電器への単位時間当たりの充電量あるいは放電量が所定量を超えるとき、前記トルク分担割合を変更することを特徴とする。
また、請求項2に係る発明の車両用動力伝達装置の制御装置によれば、前記電気式差動部の所定の部材から入力されたトルクの反力トルクを前記第1電動機および前記係合装置により受け止めることが可能とされ、前記反力トルクの前記第1電動機と前記係合装置との分担割合を、前記第1電動機による発電量からの前記第2電動機による放電量の差分値が大きい程、前記係合装置の分担割合を増加させるトルク分担率制御手段を備えるため、前記第1電動機による発電量からの前記第2電動機による放電量の差分値が大くなる、すなわち蓄電器に供給される電力が多くなると、係合装置のトルク分担割合が増加される。これにより、第1電動機が受け持つ反力トルクが小さくなって発電量が少なくなるに伴い、蓄電器に供給される電力が少なくなる。このように、蓄電器の充放電収支(充放電バランス)を好適に保つことで、蓄電器の充電容量が過充電領域に達することが事前に回避され、蓄電器の寿命を延ばすことができる。また、トルク分担率制御手段は、前記蓄電器への単位時間当たりの充電量あるいは放電量が所定量を超えるとき、前記トルク分担割合を変更するため、単位時間当たりの充電量あるいは放電量が所定量以下であれば係合装置によるトルク分担は行われない。従って、係合装置に過度の負担が係ることが抑制される。
