  • Patent number: 11499469
    Abstract: 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.
    Type: Grant

  • Patent number: 9903245
    Abstract: A system for cooling a vehicle selective catalytic reduction (SCR) may include an electronic control clutch water pump configured to circulate coolant to cool a vehicle engine, a controller configured to perform ON/OFF control of the electronic control clutch water pump when cooling of the SCR system is required in addition to the engine cooling, and a coolant circulation pathway provided in the SCR system so that the coolant associated with operation of the electronic control water pump or the electronic control clutch water pump circulates.

  • Publication number: 20160363037
    Abstract: A control method for engine thermal management that provides an electronic fan clutch and an electronic water pump in cooperation with an operation of an electronic thermostat, thereby achieving efficient engine thermal management and reducing a loss of load. The control method includes the steps of obtaining an engine coolant temperature and engine driving information and calculating a required fan rotational speed based on the obtained current coolant temperature information and the obtained engine driving information. The method calculates a control value for controlling a rotational speed of a cooling fan and checks a current operating state of the electronic thermostat. The method determines whether to operate the electronic water pump and control the cooling fan rotational speed based on the checked current operating state of the electronic thermostat, and controls the electronic water pump and the electronic fan clutch of the cooling fan based on the determination result.
