Abstract
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.
