摘要： A hybrid electric powertrain system includes a transmission, engine, e-accessory, primary and secondary electric machines, and controller. The e-accessory is powered by the secondary electric machine in response to an accessory torque demand. The engine and primary electric machine are connected to the transmission and configured, alone or in combination, to provide input drive torque to the transmission. The secondary electric machine is connected to the e-accessory and satisfies the accessory torque demand. A first clutch between the secondary electric machine and a transmission input member connects the secondary electric machine to the input member. The controller, in response to an output torque request, executes a power-sharing strategy using an objective cost function that allocates engine torque, primary motor torque, and secondary motor torque to the input member to satisfy the output torque request, while satisfying the accessory torque demand via the secondary electric machine.

摘要： An electrical system includes an engine, a motor-generator and a starter mechanism, and engine systems also include the engine. The electrical system includes a first energy storage device having a first voltage level and a second energy storage device having a second voltage level less than the first voltage level. The electrical system further includes a controller configured to control the motor-generator, the starter mechanism and first and second switching devices. Current from at least one of the first and second energy storage devices is delivered to the motor-generator when at least one of the first switching device is in a first closed state and the second switching device is in a second closed state such that the motor-generator transfers torque to the starter mechanism and the starter mechanism uses the torque to start the engine.

摘要： A powertrain includes a motor-generator and an auxiliary electric system. The powertrain also includes a first energy storage device disposed in a parallel electrical relationship with a motor-generator and an auxiliary electric system. Additionally, the powertrain includes a first switching device selectively transitionable between a first open state to electrically disconnect the first energy storage device from at least one of the motor-generator and the auxiliary electric system, and a first closed state to electrically connect the first energy storage device to at least one of the motor-generator and the auxiliary electric system. The motor-generator and the auxiliary electric system are operable regardless of the first switching device being in the first open and closed states.
