OPERATING STRATEGIES FOR A HYBRID VEHICLE

摘要

Hybrid vehicles and methods of operating the same are disclosed. Example methods may include providing a powertrain for the vehicle that includes an internal combustion engine configured to provide rotational power for a rotatable input of a transmission via a starter and an electric motor generator that includes a rotor configured to to selectively provide rotary power for the rotatable input. The method may further include selectively disconnecting the motor from the rotatable input using a disconnect device separate from the starter, whereby the rotatable input of the transmission can be driven at a speed faster than an output speed of the motor.
