Abstract
Methods and systems are provided for providing torque reserve via an electrically assisted turbocharger. A portion of requested torque reserve is provided by intentionally reducing turbine speed of an electric turbocharger by operating the associated electric motor as a generator. The resulting reduction in air mass allows for the torque reserve to be provided with reduced reliance on spark and throttle based torque reserve.
