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.
摘要翻译： 动力传动系提供有可分离的输入离合器，以允许变速器输入构件在马达的动力下独立于发动机转速旋转，并提供替代方式来为车辆附件供电，否则由发动机扭矩驱动，同时仍然允许马达启动 引擎。 提供了具有包括摩擦输入离合器和可选择单向离合器的输入离合器的并联组合的动力传动系以及这种动力系的控制方法。 控制混合动力车动力系统的另一种方法包括通过来自马达的转矩启动发动机，其中输入离合器被偏置在接合位置。 如果在不操作发动机的情况下更有效地满足车辆操作条件，则输入离合器被分离，使得仅通过马达向输出构件提供扭矩，以及可操作地连接到输入构件的车辆附件。

摘要： A compound-split electrically variable transmission has two electrical power units, two planetary gearsets, a prime mover, and two selectively engageable torque-transmitting mechanisms. The torque-transmitting mechanisms are selectively engaged to provide a reverse and first range and a second range of operation, wherein the reverse and first range is an input-split range of operation and the second range is a compound-split range of operation. The torque-transmitting mechanisms are simultaneously engaged at an interchange point between the first and second ranges of operation. This interchange point is a synchronous speed interchange point, such that the torque-transmitting mechanisms are engaged and disengaged without slipping forces being transmitted.

摘要： A two-mode, compound-split, electra-mechanical transmission utilizes an input member for receiving power from an engine, and an output member for delivering power from the transmission. First and second motor/generators are operatively connected to an energy storage device through a control for interchanging electrical power among the storage device, the first motor/generator and the second motor/generator. The transmission employs three planetary gear sets. Each planetary gear arrangement utilizes first, second and third gear members. Moreover, one gear member of the first or second planetary gear set is operatively connected to the input member, and one gear member of the third planetary gear set is selectively connected to ground. A lock-up clutch selectively locks two of the planetary gear sets in a 1:1 ratio.
