    摘要: A method of operating a hybrid powertrain having an internal combustion engine monitors a throttle intake pressure and calculates a first torque capacity from a pressure model using the throttle intake pressure as an input. The method determines a maximum expected air mass from the monitored throttle intake pressure and calculates a second torque capacity from an air mass model using the maximum expected air mass volume as an input. The method calculates a final torque capacity as a function of the first torque capacity and the second torque capacity, and sends the final torque capacity to the hybrid control processor. An engine control module receives a torque request calculated as a function of the final torque capacity. A manifold pressure request is calculated as a function of the torque request, and a throttle is actuated as a function of the manifold pressure request.

    摘要: A system and method wherein a torque monitoring algorithm compares torque demand (i.e., driver-demanded torque computed primarily from acceleration pedal position), with two independent torque estimates (e.g., one estimated from throttle position and one estimated from mass airflow (MAF) to the intake manifold). If the maximum of the two actual torque estimates exceeds the driver-demanded torque, the monitoring algorithm logic intervenes in engine torque production (e.g., shuts off fuel to cylinders) and lights a service (wrench) light. In order to prevent, or minimize, unnecessary engine torque production intervention, reducing a torque demand signal to the throttle by a factor, such factor being a function of airflow meter load divided by throttle load.
