Abstract
A method and system for determining future cylinder air-charge of an internal combustion engine having a throttle plate and an intake manifold includes a throttle position sensor for sensing a current position of the throttle plate. Control logic determines a future position of the throttle plate based on the sensed current position. Based on a model governing a change in pressure of the intake manifold and the future position of the throttle plate, the control logic then determines the future cylinder air charge.
