DETERMINING MANIFOLD PRESSURE BASED ON ENGINE TORQUE CONTROL |
摘要 |
A torque control system for an engine includes a throttle plate having an adjustable throttle position to regulate a first mass air flow into the engine. A control module estimates a previous volumetric efficiency of the engine based on a previous manifold absolute pressure (MAP) and determines a current MAP based on the previous volumetric efficiency. The control module calculates a difference between the current MAP and the previous MAP and sets a desired MAP equal to the present MAP when the difference is less than a threshold difference. The control module commands the throttle position based on the desired MAP.
