Abstract
A control system for an engine includes a target air per cylinder (APC) module, a target area module, and a phaser scheduling module. The target APC module determines a target APC based on a target spark timing, a target intake cam phaser angle, and a target exhaust cam phaser angle. The target area module determines a target opening of a throttle valve of the engine based on the target spark timing, the target intake cam phaser angle, and the target exhaust cam phaser angle. The target area module controls the throttle valve based on the target opening. The phaser scheduling module determines the target intake and exhaust cam phaser angles based on the target APC. The phaser scheduling module controls intake and exhaust cam phasers of the engine based on the target intake and exhaust cam phaser angles, respectively.
