    摘要: A control system and method of regulating operation of an engine includes a minimum torque module that determines a torque request based upon at least two of measured revolutions per minute (RPM) of an engine, a barometric pressure, and a coolant temperature of the engine. A first engine air module can determine a first desired engine air value based upon predetermined actuator values and a torque value based upon the torque request. The predetermined actuator values can include a predetermined RPM of the engine. A throttle area module can determine a desired throttle area based upon the first desired engine air value and the predetermined RPM.

    摘要: A method of achieving a desired torque output of an internal combustion engine includes determining a first air-per-cylinder (APC) value based on a first APC relationship and determining a second APC value based on a second APC relationship. An APC error is determined based on the second APC value. Operation of the engine is regulated based on the first APC value when the APC error is greater than a threshold error. Operation of the engine based on the second APC value when the APC error is not greater than the threshold error.

    摘要: An engine control system according to the principles of the present disclosure includes a manifold air pressure (MAP) determination module, a boost control module, and a throttle control module. The MAP determination module determines a desired MAP based on a driver torque request. The boost control module controls a boost device based on the desired MAP and a basic boost pressure. The boost device is actuated using boost pressure and the boost pressure is insufficient to actuate the boost device when the boost pressure is less than the basic boost pressure. The throttle control module controls a throttle valve based on the desired MAP and the basic boost pressure.

    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 system includes a power request module, a first desired engine speed (DRPM) determination module, a driver torque request module, and an actuation module. The power request module generates a power request for an engine of the vehicle based on an accelerator pedal position and a vehicle speed. The first DRPM determination module determines a first target DRPM based on the power request, a turbine speed of a torque converter, and a k-factor of the torque converter. The driver torque request module selectively generates a torque request for the engine based on the power request and the first target DRPM. The actuation module controls at least one engine actuator based on the torque request.
