Patent ID: 6966287

Claim:
A torque control system for regulating operation of a displacement on demand engine that is operable in an activated mode and a deactivated mode, comprising: a throttle that regulates air flow into said engine; a cam phaser that regulates a torque output of said engine; a first module that determines a throttle area based on a desired deactivated manifold absolute pressure (MAP) and a desired mass air flow (MAF); a second module that determines a desired cam phaser position based on an engine speed and a transitional air per cylinder (APC) that is determined based on one of a desired deactivated APC and a desired activated APC; a third module that generates a throttle control signal to control said throttle based on said throttle area; and a fourth module that generates a cam phaser control signal to control said cam phaser based on said desired cam phaser position.
