Abstract: A transmission mechanism with a pair of selectively engageable clutch systems has an upstream gear ratio and a downstream gear ratio that combine to provide an effective gear ratio. A different clutch drive member is associated with an input side of each of the pair of clutch systems. The clutch drive members are driven for rotation by an engine input member. The upstream gear ratio is determined by the gear ratio between the engine input member and one of the clutch drive members. Output sides of each of the clutch systems drive an associated one of a pair of non-coaxial layshafts. Pinions are located on and selectively driven by the layshafts. A countershaft is spaced from both of the layshafts, and has a plurality of gears. Each of the gears is driven for rotation by one of the pinions of the layshafts. The downstream gear ratio is determined by the gear ratio between the selected pinion and the intermeshed gear.

Abstract: A hybrid electric vehicle powertrain having a mechanical power source and an electro-mechanical power source, including a generator, a motor and a battery. Driving torque developed by the mechanical power source is delivered through one clutch of a geared transmission to a power output shaft. The electric motor of the electro-mechanical power source delivers driving torque through a second clutch of the geared transmission. A mechanical reverse drive torque is used to improve reverse drive performance. A reduction in duration of operation in a negative power split during a driving event is achieved to improve vehicle powertrain efficiency. A series drive is available as the mechanical power source drives the generator to charge the battery, which drives the motor. The generator may act as an engine starter motor.
