Abstract:
1. A system comprising: a parameter module that determines at least one of a position of a throttle and a load of an engine, wherein the engine comprises a plurality of cylinders; a cylinder status module that generates a status signal indicating an activation status for each of the plurality of cylinders, wherein the cylinder status module determines whether one or more of the plurality of cylinders are deactivated; a first pressure prediction module that, when all of the plurality of cylinders are activated, predicts first intake port pressures for the plurality of cylinders according to a first model and based on the at least one of the position of the throttle and the load of the engine; a second pressure prediction module that, when one or more of the plurality of cylinders is deactivated, predicts second intake port pressures for the deactivated cylinders according to a second model and based on the status signal and the at least one of the position of the throttle and the load of the engine; and a fuel control module configured to adjust fuel to or torque output of the engine based on the first intake port pressure and the second intake port pressure.
