PROBLEM TO BE SOLVED: To solve a problem where drive torque fundamentally required for preventing an over rotation of a rotary electric machine is limited, causing a driver to feel discomfort, the problem being associated with the case of a drive wheel idling.SOLUTION: A control apparatus is for use in a power transmission device TM that includes: a power distribution mechanism that has a first rotary element connected to an engine, a second rotary element connected to a rotor of a first rotary electric machine, and a third rotary element, and is capable of distributing power from the first rotary element to at least one of the second and third rotary elements, or from the second rotary element to at least one of the first and third rotary elements; a hydraulic coupling including an input shaft for connecting to the third rotary element and the rotor of the second rotary electric machine, and an output shaft for connecting to a drive wheel W-side of the vehicle; and a frictional engagement element capable of directly connecting between the input and output shaft sides of the hydraulic coupling. Furthermore, in the case of a rotation speed Nof the first rotary electric machine exceeding a speed threshold N, the control apparatus controls an operation of the frictional engagement element so that the direct connection state of the input and output shafts sides of the hydraulic coupling is disengaged.SELECTED DRAWING: Figure 8

    【課題】駆動輪が空転状態となった場合、回転電機の過回転を防止するために本来必要とされる駆動トルクに制限が掛かり、運転者に違和感を与えてしまう。【解決手段】エンジンに接続する第1の回転要素,第1の回転電機の回転子に接続する第2の回転要素,第3の回転要素を有し、第1の回転要素から第2および第3の回転要素の少なくとも一方、または第2の回転要素から第1および第3の回転要素の少なくとも一方へと動力を振り分けることができる動力分割機構と、第3の回転要素および第2の回転電機の回転子に接続する入力軸ならびに車両の駆動輪W側に接続する出力軸を有する流体継手と、流体継手の入/出力軸側を直結し得る摩擦係合要素とを含む本発明による動力伝達装置TMの制御装置は、第1の回転電機の回転速度NG1が速度閾値NLを越えた場合、流体継手の入/出力軸側の直結状態が解除されるように摩擦係合要素の作動を制御する。【選択図】図8
