    摘要： An electro-mechanical transmission is provided having only a single motor/generator, at least one differential gear set and two torque-transmitting mechanisms. A first of the torque-transmitting mechanisms is selectively engageable to establish a first continuously variable operating mode and a second of the torque-transmitting mechanisms selectively engageable to establish a second continuously variable operating mode and a synchronous shift between the two operating modes is achievable. A method of control is provided in which vehicle operating characteristics are analyzed to identify a target operating state in terms of operating mode and ratio based on the available motor torque and motor power and on maximizing energy efficiency. The transmission is controlled to approach this operating mode as closely as possible and the diverge away from the optimum torque operating with zero net battery use as the battery charge of the battery connected with the motor/generator accumulates or depletes.

    摘要： An electrically-variable transmission is provided with first and second motor/generators and three planetary gear sets. The planetary gear sets have continuous interconnections, and selective connections via a plurality of torque-transmitting mechanisms, that provide three forward electrically-variable modes. Preferably, the planetary gear sets are characterized by effective gear ratios such that a substantially equal maximum torque is required from each of the motor/generators during the three forward electrically-variable modes for a given torque on the input member. This allows the first and second motor/generators to be substantially equal in size.

    摘要： A powertrain is provided with an input clutch that is disengagable to allow a transmission input member to rotate independently of engine speed under power of a motor and provide an alternative way to power vehicle accessories otherwise driven by engine torque, while still allowing the motor to start the engine. A powertrain having a parallel combination of input clutches including a friction input clutch and a selectable one-way clutch is provided, as well as a method of control of such a powertrain. Another method of controlling a hybrid vehicle powertrain includes starting the engine via torque from a motor with the input clutch biased in an engaged position. If vehicle operating conditions are more efficiently met without operating the engine, the input clutch is disengaged to so that torque is provided only by the motor to the output member and to vehicle accessories operatively connected to the input member.
