摘要： A hybrid powertrain is provided for a vehicle that has a first axle and a second axle. The hybrid powertrain includes an engine, a stationary member, and an electrically-variable transmission that has a first and a second interconnected planetary gear set and a first and a second motor/generator. The engine, the first motor/generator, the second motor/generator and the first axle are each operatively connectable for rotation with a different member of the first and the second planetary gear sets. The powertrain has an electric drive unit that has reduction gearing and a third motor/generator. The third motor/generator and the second axle are each operatively connected to a different member of the third planetary gear set. The powertrain is operable in a compound-split operating mode.

摘要： A hybrid transmission is provided with a motor and a torque-transfer device is operable to transfer torque from the motor to a transmission input member upstream in power flow from the transmission gearing arrangement. The torque transfer device may be a fluid coupling, such as a torque converter, including a torque converter lock-up clutch. In other embodiments, the torque transfer device is a launch clutch that may be either a wet clutch engagable via pressurized transmission fluid, or a dry clutch, such as used in a manual transmission. A disconnect clutch is selectively engagable to operatively connect an engine connection member with the motor to permit the motor to start the engine, such as after a stop. Many embodiments of the transmission include a one-way clutch arranged in parallel with the disconnect clutch. A method of starting the engine using such a transmission is also provided.

摘要： A hybrid transmission having an input member, an output member, and a single motor/generator is characterized by a plurality of fixed-ratio modes of operation and at least one electrically variable mode of operation. In the fixed-ratio modes of operation, the speed ratio between the input member and the output member is independent of the speed of the motor/generator. In the electrically variable mode of operation, the speed ratio between the input member and the output member is dependent upon the speed of the motor/generator.

摘要： A hybrid powertrain has an electrically-variable transmission with a compound planetary gear set that may be only two planetary gear sets. Two members of the first planetary gear set are connected for common rotation with two members of the second planetary gear set. A first motor/generator is connected for common rotation with a member of the first planetary gear set and a member of the second planetary gear set. An input member is connected to another member of the first planetary gear set. A first set of intermeshing gears includes a first gear connected for common rotation with one of the gears of the second planetary gear set and a second gear driven by a second motor/generator. A second set of intermeshing gears includes another gear driving the output member. A first clutch is engageable to establish an input-split mode. A second clutch is engageable to establish a compound-split mode.

摘要： A hydraulic control system for a transmission includes a motor, a sump for storing a hydraulic fluid, and a dual element pump connected to the motor. The dual element pump has at least one input port connected to the sump, a first outlet port, and a second outlet port. The dual element pump provides a first volume of hydraulic fluid to the first outlet port and provides a second volume of hydraulic fluid to the second outlet port. The first volume is greater than the second volume. The first outlet port is connected to a diversion valve. The second outlet port is connected to a high pressure hydraulic circuit. The diversion valve is operable to transmit the hydraulic fluid from the first outlet port to a low pressure hydraulic circuit and the high pressure hydraulic circuit.
