A controller is configured to receive a signal representative of the input parameter state; process an actuator state through a flow model of the thermal system to obtain an existing flow in the fluid conduits; process the existing flow through a thermal model of the thermal system to determine an input that reduces an error between a desired parameter state and the input parameter state; process the input through an inverse flow model to convert the input to a desired actuator state; and position the actuator in the desired actuator state.

A system comprising a computer including a processor and a memory, the memory including instructions such that the processor is programmed to: receive at least one of expected upcoming traffic behavior or actual upcoming traffic behavior corresponding to an upcoming segment of a roadway being traversed by a vehicle; adjust a radiator hysteresis timer based on the expected upcoming traffic behavior or the actual upcoming traffic behavior; and transmit a control signal to an actuator to actuate a radiator fan based on the adjusted radiator hysteresis timer.

The present disclosure relates to a thermostat fault diagnosis method. The method includes: a current environment temperature and a boundary temperature and initial opening temperature corresponding to the current environment temperature are acquired; engine thermal equilibrium state data determined based on coolant temperature change data in an engine are acquired; a current coolant temperature is acquired; and according to the engine thermal equilibrium state data and a relationship between the current coolant temperature and the boundary temperature and initial opening temperature, it is judged whether a thermostat is faulty.

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.

Methods and systems are provided for diagnosing an active grille shutter (AGS) system. In one example, a method may include indicating degradation of an AGS system of a vehicle based on an infrared image information obtained from a camera coupled to the vehicle and adjusting one or more engine operating parameters responsive to the indicating.

Cooling systems of a work vehicle that provide targeted cooling, regenerative cooling and/or a combination therein. A cooling system includes plural fans configured to provide airflow across a radiator and a fan controller in communication with the plural fans. The fan controller is configured to receive operating condition data associated with at least one of the radiator and an engine. The fan controller is configured to determine a total target heat rejection value based on the operating condition data; determine a plurality of target fan operation values for the plural fans, based on the total target heat rejection value and the operating condition data; and control operation of the plural fans at plural independent fan speeds based on the plural fan operation values.

An apparatus and method of controlling heat of an engine compartment when stopped are provided. The apparatus and method of controlling heat of an engine compartment improve fuel efficiency by managing heat of the engine compartment when a vehicle is stopped after driving.

A system for controlling an air heat exchanger of a vehicle includes an information collector which collects environmental information including a current speed of a vehicle, a desired air mass flow rate, and an ambient temperature. A storage stores the environmental information therein. A controller calculates a driving load and a cooling load in accordance with the environmental information and calculating a control amount of an air heat exchanger, at which a cost function that is a sum of the driving load and the cooling load is minimum.

Methods and systems are provided for reducing ice formation in a charge air cooler. In one example, a method includes, operating a radiator fan of a vehicle in a first direction to cool an engine of the vehicle, and reversing a direction of rotation of the radiator fan to blow heated air towards a charge air cooler, the charge air cooler arranged proximate a radiator of the vehicle. Operating the radiator fan in a first direction may be based on the engagement of one or more gears of a transmission of the vehicle while operating the radiator fan in the reverse direction may be based on an engine temperature condition, one or more ambient weather conditions, and an engine idle condition.

An apparatus of decreasing intake air temperature of an engine includes: a first cooling circuit including a compressor, a condenser, a first expansion valve, and an evaporator disposed along a first cooling line through which refrigerant flows; a second cooling circuit including the compressor, the condenser, a second expansion valve, and a chiller disposed along a second cooling line through which the refrigerant flows; and a third cooling circuit including an electric water pump, the chiller, an intercooler, and a radiator disposed along a third cooling line through which coolant flows.
