摘要：
A powertrain for a vehicle includes an engine and a transmission having an input member, an output member, and a neutral state in which torque is not transmitted from the input member to the output member. A first motor/generator is coupled to the engine. A second motor/generator is coupled with vehicle wheels directly or indirectly through the transmission. The first motor/generator acts as a generator when powered by the engine to provide electric power to the second motor/generator. The second motor/generator acts as a motor when receiving electric power from a battery or from the first motor/generator. A shift selector is moved by a vehicle operator to establish an electric propulsion mode in which the transmission is in the neutral state and the second motor/generator functions as a motor.
