  "textContent": "A vehicular drive system includes (i) an electrically controlled differential portion (16) including a differential mechanism (11) having a first element (RE1) operatively connected to an engine (8) in a drive-power transmissive state, a second element (RE2) connected to a first electric motor (M1), and a third element (RE3) connected to both a power transmitting member (18) and a second electric motor (M2), and distributing an output of the engine to the first electric motor and the power transmitting member, and (ii) a shifting portion (20) disposed in a power transmitting path between the power transmitting member and drive wheels (34). When a rotation speed of a given rotary element (RE4 to RE8) of the shifting portion (20) exceeds a first given rotation speed, or when falling of the rotation speed of the given rotary element of the shifting portion in a given high speed rotation state is predicted, a control device (80) limits a rotation speed (NE) of the engine (8) by a third electric motor (M3) connected to the engine.",
