摘要： Vehicular drive system which is small-sized and/or improved in its fuel economy.A power distributing mechanism 16, which is provided with a differential-state switching device in the form of a switching clutch C0 and a switching brake B0, is switchable by the switching device between a differential state (continuously-variable shifting state) in which the mechanism is operable as an electrically controlled continuously variable transmission, and a fixed-speed-ratio shifting state in which the mechanism is operable as a transmission having a fixed speed ratio or ratios. The power distributing mechanism 16 is placed in the fixed-speed-ratio shifting state during a high-speed running of the vehicle or a high-speed operation of engine 8, so that the output of the engine 8 is transmitted to drive wheels 38 primarily through a mechanical power transmitting path, whereby fuel economy of the vehicle is improved owing to reduction of a loss of conversion of a mechanical energy into an electric energy. The mechanism 16 is also placed in the fixed-speed-ratio shifting state during a high-output operation of the engine 8, so that the required electric reaction of first electric motor M1 can be reduced, whereby the required size of the first electric motor M1, and the required size of the drive system 10 including the electric motor M1 can be reduced.

摘要： Hybrid controller 52 for a vehicular drive system is operable during a shifting control of step-variable transmission portion 20 for a stepping change of its speed ratio, for changing a speed ratio of continuously-variable transmission portion 11, such that total speed ratio γT of transmission mechanism 10 defined by the speed ratio of the continuously-variable transmission portion 11 and the speed ratio of the step-variable transmission portion 20 is continuously changed, irrespective of the stepping change of the speed ratio of the step-variable transmission portion 20, so that an amount of stepping change of engine speed NE before and after a shifting action of the step-variable transmission portion 20 is reduced, and a shifting shock of the step-variable transmission portion 20 is reduced. The hybrid controller 52 permits the transmission mechanism 10 to function as a continuously variable transmission, thereby improving fuel economy of the vehicular drive system.

摘要： Vehicle-starting-engine-torque restricting means 86 is provided to restrict engine torque TE upon starting of a vehicle with engine 8 used as a vehicle drive power source, so that a required output of first electric motor M1 which generates a reaction force corresponding to the engine torque TE can be made smaller than in the case where the engine torque TE is not restricted. Namely, the vehicle-starting-engine-torque restricting means 86 eliminates a need of increasing the maximum output of the first electric motor M1 to generate the reaction force corresponding to the engine torque TE, making it possible to reduce the required size of the first electric motor M1.
