A switching clutch C0 or switching brake B0 is provided for placing a shifting mechanism 10 in a continuously variable shifting state and a step variable shifting state, enabling the drive apparatus to have combined advantages including a fuel economy improving effect of a transmission, enabled to electrically change a speed ratio, and a high transmitting efficiency of a gear type transmitting device enabled to mechanically transmit drive power.

A control apparatus for a shift-position changing mechanism includes a detection unit that is provided on a path along which the operation member with a magnetic member moves, and that detects a change in the magnetic field due to a positional change of the operation member; and a determination unit that determines the shift position corresponding to the operated position of the operation member based on the detected change in the magnetic field and predetermined multiple modes of changes in the magnetic field, which correspond to the respective shift positions. The predetermined modes are set such that, when the detected change in the magnetic field is influenced by a change in the magnetic field due to a factor different from the positional change of the operation member, a likelihood that the determination unit determines that the running shift position, at which a vehicle is able to run, is selected is reduced.

A transmission mechanism including a switching clutch or brake is switchable between a continuously-variable shifting state and a step-variable shifting state, and provides improved fuel economy by a transmission with an electrically variable speed ratio and high power transmitting efficiency by a gear type power transmitting device constructed for mechanical transmission of power. During four-wheel drive vehicle running with second drive wheels driven by a third electric motor, a switching control switches a differential portion to a continuously-variable shifting state, so that an operating speed of a first electric motor operated by an output of an engine as an electric generator is controlled to assure a higher degree of electricity generating efficiency, owing to the differential function of the differential portion, than when the differential portion is placed in a non-continuously-variable shifting state in which first electric motor speed and engine speed are determined by vehicle running speed.

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.
