A hybrid vehicle system is provided with an internal combustion engine driving one set of wheels and an electric motor connected to the other wheels via an active clutch system. A power take-off unit is provided for selectively providing driving torque from the internal combustion engine to the electric motor to operate the motor in a regenerative operating mode. The active clutch system is selectively engaged and disengaged based upon whether the vehicle is operating in an internal combustion engine operating mode, an electric motor operating mode, a combined electric motor and internal combustion engine operating mode, or a regenerative operating mode.

A transmission system for an automotive vehicle as claimed in claim 4, wherein the second clutch comprises: a first cylindrical member of a bell-shaped cylindrical form integrally installed on an outer periphery of the output axle, a first spline formed on an outer periphery of the first cylindrical member of the bell-shaped cylindrical form integrally installed on an outer periphery of a disc portion of the first rotary body; a second spline formed on an inner periphery of the second cylindrical member so as to be opposed to the first spline; and a second multiple-plate clutch comprising inner clutch plates and outer clutch plates engaged to both of the first and second splines. 6. A transmission system for an automotive vehicle as claimed in claim 5, wherein the third clutch is disposed coaxially with the first clutch in an outer diameter direction of the first clutch and comprises a third rotary body integrally installed on the center axle and comprising a disc-shaped plate and a cylindrical plate coupled to an outer peripheral edge of the disc-shaped plate; a third spline formed on an outer periphery of the cylindrical plate of the third rotary body; a fourth spline formed on an inner periphery of a third cylindrical member installed on an outer periphery of a second rotary body integrally installed on the sun gear; and a third multiple-plate clutch comprising inner clutch plates and outer clutch plates interposed between the third and fourth splines and enabled to be moved in the axial direction of the center axle. 7. A transmission system for an automotive vehicle as claimed in claim 6, wherein the control cam of each of the first clutch, second clutch, and third clutch comprises: a thrust roller attached onto the first ring, the first ring being enabled to rotate together with a center axle in a floating support state on a circular member with oil intervened between the circular member fixed onto an outer periphery of the center axle and the first ring itself and an axial movement of the first ring being limited; and a cam groove formed on an opposing surface of thrust roller and wherein when a torque in a relative rotation direction is developed between the first ring and the second ring, the second ring being supported onto the circular member in the floating support state and being enabled to be moved in the axial direction of the center axle, the thrust roller runs on a slanted surface of the cam groove so that the torque developed between the first and second rings is amplified by a multiplication factor in accordance with a gradient of the slanted surface of the cam groove and is converted into a pressure in the axial direction of the center axle. 8. A transmission system for an automotive vehicle as claimed in claim 1, further comprising a generator/motor which is installed within the housing and comprising a stator and a rotor, an energy supply and receipt being enabled between the stator of the generator/motor and the rotor thereof, the rotor being interposed between the sun gear and the third clutch and being attached onto a rotary body rotated together with the sun gear, and the stator being supported on the housing and being opposed to the rotor. 9. A transmission system for an automotive vehicle as claimed in claim 8, further comprising a controller to switch between a clutching and a release of each of the first clutch, the second clutch, and the third clutch and to switch a function of the generator/motor between a power generator and a motor and wherein
