Abstract: A system includes a soot module, a coordinator module, a regeneration module, and actuator modules. The soot module determines a current amount of soot mass in a particulate filter of a gasoline engine, where the particulate filter is downstream from the gasoline engine and receives an exhaust gas from the gasoline engine. The coordinator module generates an enable signal, a torque reserve signal, and an equivalence ratio. The regeneration module, based on the current amount of soot mass and the enable signal, generates a regeneration signal to regenerate the particulate filter. The actuator modules, based on the regeneration signal, the torque reserve signal and the equivalence ratio, retard spark and increase an amount of air flow to the particulate filter. The actuators maintain a same amount of torque out of the gasoline engine during regeneration as output from the gasoline engine prior to the regeneration of the particulate filter.

Abstract: A pump current module determines a first current flowing through an electric engine coolant pump based on a coolant valve position. A current error module receives a second current flowing through the electric engine coolant pump measured using a current sensor and determines a current error based on a difference between the first current and the second current. A fault module indicates whether a fault is present based on the current error.

Abstract: A method is disclosed for optimizing fuel economy during an engine warm up phase of operation of an internal combustion engine. An exhaust manifold may have a coolant jacket through which a coolant may flow. A temperature of the coolant in the exhaust manifold may be determined to detect when it is at a predetermined maximum threshold, which represents a temperature threshold just below a temperature at which the coolant will begin to boil. When this threshold is reached, then a determination may be made as to a minimum rate of flow of the coolant through the exhaust manifold which maintains the coolant at about the predetermined maximum threshold, and the coolant may be flowed through the exhaust manifold at the determined minimum rate of flow.

Abstract: A coolant control system of a vehicle includes first and second target flowrate modules, a target speed module, and a speed control module. The first target flowrate module determines a first target flowrate of coolant through an engine. The second target flowrate module, when a change in heat input to the engine is greater than a predetermined value, sets a second target flowrate to greater than the first target flowrate. The target speed module determines a target speed of an engine coolant pump based on the second target flowrate. The speed control module controls a speed of the engine coolant pump based on the target speed.

Abstract: A target speed module determines a target speed of an engine coolant pump of the vehicle. A speed adjustment module determines a speed adjustment based on a position of a valve, wherein a backpressure of the engine coolant pump changes when the position of the valve changes. An adjusted target speed module determines an adjusted target speed for the engine coolant pump based on the target speed and the speed adjustment. A speed control module controls a speed of the engine coolant pump based on the adjusted target speed.
