    摘要: A ranking module determines N ranking values for N predetermined cylinder activation/deactivation sequences of an engine, respectively. N is an integer greater than or equal to two. A cylinder control module, based on the N ranking values, selects one of the N predetermined cylinder activation/deactivation sequences as a desired cylinder activation/deactivation sequence for cylinders of the engine. The cylinder control module also: activates opening of intake and exhaust valves of first ones of the cylinders that are to be activated based on the desired cylinder activation/deactivation sequence; and deactivates opening of intake and exhaust valves of second ones of the cylinders that are to be deactivated based on the desired cylinder activation/deactivation sequence. A fuel control module provides fuel to the first ones of the cylinders and disables fueling to the second ones of the cylinders.

    摘要: A system including a target module determining a target temperature of coolant at an input of an engine for a maximum amount of fuel efficiency. A mode module disables closed loop control based on temperatures of coolant entering the engine and at an output of a radiator. An open loop module determines first and second temperatures of coolant at inputs of a coolant control valve that receive coolant from the radiator and a channel that bypasses the radiator. A ratio module determines a ratio based on the first and second temperatures and the temperatures of the coolant entering the engine and at the radiator output. A closed loop module generates a correction value based on the target temperature and the temperature of the coolant entering the engine. A position module adjusts the coolant control valve based on the ratio, the correction value and whether closed loop control is disabled.

    摘要: A fuel control system of a vehicle includes an injection control module and a command module. The injection control module determines a first target amount of fuel for a combustion event of an engine. A command module selectively command the injection control module to provide two fuel injections when a torque request decreases. In response to the command, the injection control module: determines second and third target amounts of fuel based on the first target amount; provides a first fuel injection during the combustion event based on the second target amount; and provides a second fuel injection during a compression stroke of the combustion event based on the third target amount.

    摘要: An engine control system for a vehicle includes a target torque module that determines a target torque output of an engine based on at least one driver input. A target air per cylinder (APC) module determines a target APC for the engine based on the target torque. A target mass airflow (MAF) module determines a target MAF through a throttle valve of the engine based on the target APC, a number of activated cylinders of the engine, and a total number of cylinders of the engine. A throttle control module determines a target throttle opening based on the target MAF and controls opening of the throttle valve based on the target throttle opening.
