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 electric torque converter has a torque converter input member connected to the first node of a differential gear set representable by a lever diagram having first, second, and third nodes. A motor/generator is connected to the second node. The third node is connected to an input member of a transmission gearing arrangement. A brake is selectively engagable to ground the first node to a stationary member. Engagement of the brake provides a regenerative braking mode and an electric-only driving mode, with the motor/generator connected to the transmission gearing arrangement through the differential gear set. Various clutches may be provided for lock-up or selective connection of the engine, including arrangements which reduce motor/generator torque required for engine starting while in electric-only driving. A method of operating a vehicle maintains the engine speed at an optimum level to the extent possible given battery charge levels and operator commands.

摘要： An electromechanical transmission is provided with a structural support member that supports a motor/generator in a space efficient way; particularly, the motor/generator is supported from one side only to save space axially in the transmission. Specifically, a stationary structural support member circumscribes an outer surface of and supports a stator while extending radially-inward of a rotor and at least partially supporting the rotor. A rotor hub rotatable with respect to the structural support member is used to support an inner surface of the rotor. The structural support member substantially encloses the stator and rotor from one direction along the axis of rotation. However, the stator and rotor have no additional support members in the opposing axial direction such that they are unenclosed from an opposing axial direction.

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 single range, electrically variable transmission (EVT) is provided with a lockup clutch that reduces motor power requirements. When applied, the lockup clutch allows engine torque to be transmitted directly to the output without the necessity of a motor/generator supplying reaction torque. With the lockup clutch applied, the transmission operates with zero electro-mechanical power flow at a fixed mechanical ratio, thus mitigating the power peak which occurs through the motor/generators. Input-split, output-split, and compound-split transmissions are disclosed. A method of operating an EVT with a lockup clutch is also provided.

摘要： A powertrain incorporates two electrical units, two planetary gearsets in a radially-stacked package to provide a shortened length of the transmission. The output members of the electrical units are interconnected by a gear mechanism, which is drivingly connected with a conventional differential mechanism, which is aligned within the radial package of the electrical units. The electrical units combine with power from an engine to provide a two-mode compound-split electrically-variable transmission.
