generator 32 may be referred to as an electric machine which when utilized in other vehicle powertrain configurations is capable of both generating electric power and providing motive power when the engine 18 is driveably coupled to the planetary gear set 24 the generator 32 generates energy as a reactionary element to the operation of the planetary gear set 24 electric energy generated from the generator 32 is transferred to the battery 14 through electrical connections 36 the battery 14 also receives and stores electric energy through regenerative braking in known fashion the battery 14 supplies the stored electric energy to the motor 16 for operation the portion of the power delivered from the engine 18 to the generator 32 may also be transmitted directly to the motor 16 the battery 14 motor 16 and generator 32 are each interconnected in a two way electric flow path through electrical connections 36 the vehicle control system 12 controls the components in the powertrain to provide proper torque distribution to the wheels it should be understood that the motor 16 and the generator 32 can both be referred to as an electric machine each electric machine can operate as a generator by receiving torque from the engine 18 and supplying ac voltage to the inverter 15 whereby the inverter 15 converts the voltage into dc voltage to charge the battery 14 each electric machine can also operate as a generator by utilizing regenerative braking to convert the braking energy of the vehicle into electric energy to be stored in the battery 14 alternatively each electric machine can operate as a motor whereby the electric machine receives power from the inverter 15 and the battery 14 and provides torque through.
