A system and approach for development of setpoints for a controller of a powertrain system. The controller may be parameterized as a function of setpoints to provide performance variables that are considered acceptable by a user or operator for current operating conditions of the engine or powertrain. The controller may determine set point trajectories in real time during operation of the powertrain system and determine positions of manipulated variables do drive controlled variables to associated and determined set point trajectories. The present system and approach may determine set point trajectories for powertrain conditions on-line and in real time, whereas set point trajectories have previously been determined off-line for powertrain control.

The present invention relates to a cooling control apparatus which performs control for cooling an internal combustion engine by causing an electric pump to circulate cooling water and causing an electric fan to supply cooling air to a radiator. The cooling control apparatus comprises an electric pump for circulating a coolant through a coolant passage formed in the internal combustion engine, and a radiator and a radiator fan which are for cooling the coolant. When the internal combustion engine stops after completion of warming-up, the radiator fan and the electric pump are driven to cool the internal combustion engine, and when a temperature of the coolant decreases to less than a temperature at a time of engine stop, the radiator fan is stopped in a state in which the electric pump is operated.

Methods and systems are provided for adjusting a grille shutter opening based on an estimated amount of fuel in oil dilution. In one example, a method may include adjusting a grille shutter opening to a closed position in response to an oil dilution amount above a threshold, the position determined based on the oil dilution amount in addition to each of engine coolant temperature and acceleration/deceleration.

A valve assembly is provided, including at least a first valve unit and a second valve unit. The first valve unit is movably mounted within the second valve unit, and includes a first valve housing defining a first valve volume. The second valve unit includes a second valve housing defining a second valve volume different from the first valve volume. The second valve housing includes at least one first port and at least one second port. The first valve unit includes a first valve element reciprocably movable with respect to the first valve seat to selectively open and close a first fluid path through the first valve volume, and a first mechanical biasing element. The second valve unit includes a second valve element reciprocably movable with respect to the second valve seat to selectively open and close a second fluid path through the second valve chamber, the second valve element being affixed to first valve housing for reciprocal movement therewith; and a second mechanical biasing element. The first valve unit is connectable to a reciprocable actuator element, the first valve element and the second valve elements being reciprocally movable responsive to reciprocal movement of the reciprocable actuator element to selectively open the first flow path and the second flow path, respectively.

An engine cooling control apparatus, a system including the same, and a method thereof provide an engine cooling control apparatus including a processor configured to calculate a required fan rotation speed for controlling a cooling fan based on proportional integral (PI) control and a storage configured to store data acquired by the processor and an algorithm for driving the processor. The processor classifies a plurality of control regions depending on a coolant temperature and adjusts and outputs the required fan rotation speed for each of the control regions.

A system including a cooling fan, an actuator with an actuator temperature sensor, and a controller is disclosed. The controller may be configured to receive temperature data from the actuator temperature sensor. The temperature data may include information relating to an actuator temperature of the actuator. The controller may be configured to compare the actuator temperature with a temperature threshold associated with the actuator, and control the cooling fan to adjust the actuator temperature based on determining that the actuator temperature satisfies the temperature threshold.

A method of controlling a cooling system includes, by an integrated controller: controller area network (CAN) checking whether CAN communication is abnormal after a vehicle is turned on and control of a cooling fan and an active air flap is initiated; single-communication checking whether communication with a cooling fan controller and an active air flap (AAF) controller is abnormal; performing a first fail-safe operation of communicating with the cooling fan controller and the AAF controller; and controlling the cooling fan and the active air flap based on signals of a first temperature sensor of the cooling fan controller and a second temperature sensor of the AAF controller.

A cooling device includes a surrounding member, an air inlet, an air outlet, and a flow-path-formation mechanism. The surrounding member is configured to surround an engine. The air inlet is formed in the surrounding member. The air outlet is formed in the surrounding member and is to be coupled to an intake pipe of the engine. The flow-path-formation mechanism is configured to form a flow path that allows outside air to circulate to the air outlet from the air inlet when a temperature of the engine or a temperature inside the surrounding member is greater than or equal to a predetermined temperature.

Power systems and enclosures having a configurable cooling air flow are disclosed. The power system includes an enclosure; an air inlet location, a first air outlet location, a second air outlet location, a fan assembly, and one or more relocatable covers to obstruct the first and second air outlet locations. The air inlet location may be at a first location on an exterior of the enclosure to permit intake of air from the exterior of the enclosure to an interior of the enclosure. The first air outlet location may be at a second location on the exterior of the enclosure to expel air taken in through the air inlet location, while the second air outlet location at a third location on the exterior of the enclosure to expel air taken in through the air inlet location.

A thermal energy control apparatus for a hybrid vehicle is capable of efficiently managing thermal energy. The apparatus includes an integrated thermal management (ITM) unit that adjusts a coolant temperature by opening or closing a radiator valve and an active air flap (AAF) unit that adjusts an intake amount of ambient air by opening or closing a flap valve. A cooperative controller cooperatively operates the ITM and AFF units. The cooperative controller determines, based on a coolant temperature, whether a cooperative control mode is to be executed, adjusts an opening degree of the flap valve when the cooperative control mode is a cooperative control mode of the AFF unit, and adjusts an opening degree of the radiator valve when the cooperative control mode is a cooperative control mode of the ITM unit.
