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.
Claims17
An engine cooling control apparatus comprising:
- 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,
- wherein 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, and
- wherein the processor controls driving of the cooling fan by using a required fan rotation speed that is inputted by a user in a case of a low temperature region where the coolant temperature is smaller than a predetermined first threshold value.
A vehicle system comprising:
- an engine cooling control apparatus configured to calculate a required fan rotation speed for controlling a cooling fan based on proportional integral (PI) control, to classify a plurality of control regions depending on a coolant temperature, and to adjust and output the required fan rotation speed for each of the control regions;
- and
- an electronic fan clutch configured to output a control signal for controlling a cooling fan depending on the required fan rotation speed, and
- wherein the engine cooling control apparatus controls driving of the cooling fan by using a required fan rotation speed that is inputted by a user in the case of a low temperature region where the coolant temperature is smaller than a predetermined first threshold value.
An engine cooling control method comprising:
- calculating a required fan rotation speed for controlling a cooling fan based on proportional integral (PI) control;
- classifying a plurality of control regions depending on a coolant temperature;
- and
- adjusting and outputting the required fan rotation speed for each of the control regions,
- wherein the adjusting and outputting of the required fan rotation speed includes controlling driving of the cooling fan by using a required fan rotation speed that is inputted by a user in the case of a low temperature region where the coolant temperature is smaller than a predetermined first threshold value.
