    摘要: A control system for an engine includes a selecting module, a target air per cylinder (APC) module, and a phaser scheduling module. The selecting module: selects one of (a) target intake and exhaust cam phaser angles and (b) measured intake and exhaust cam phaser angles; and sets selected intake and exhaust cam phaser angles based on the selected one of the target intake and exhaust cam phaser angles and the measured intake and exhaust cam phaser angles, respectively. The target APC module determines a target APC based on a target spark timing and the selected intake and exhaust cam phaser angles. The phaser scheduling module determines the target intake and exhaust cam phaser angles based on the target APC and controls intake and exhaust cam phasers of the engine based on the target intake and exhaust cam phaser angles, respectively.

    摘要: A control system for an engine includes an engine torque request module, an engine torque response module, a torque command limit module, and an actuation module. The engine torque request module determines an engine torque request based on (i) an engine power request and (ii) a desired engine speed (DRPM). The engine torque response module determines first and second torque values based on (i) an engine torque response model and (ii) first and second torque boundaries, wherein the first and second torque boundaries are based on the DRPM and a measured engine speed (RPM). The torque command limit module generates a secured engine torque request based on (i) the engine torque request and (ii) the first and second torque values. The actuation module controls at least one actuator of the engine based on the secured engine torque request.

    摘要: A torque control system for an engine includes a first module that estimates a first engine torque based on an air-per-cylinder (APC) value and a second module that estimates a second engine torque based on a manifold absolute pressure (MAP). A third module determines a desired MAP based on the first engine torque and the second engine torque. A throttle opening is regulated based on the desired MAP.
