摘要： Control system for a work vehicle (10; 10') comprising a radiator (20), a fan (21) for generating an air flow directed towards the radiator (20) to perform a cleaning operation thereof, a temperature sensor (22; 22', 23') adapted to detect a temperature (T) of a portion of the work vehicle (10). The control system (1; 1') comprises a control unit (2) operatively connected to the temperature sensor (22; 22', 23') and the fan (21). The control unit (2) is configured to command the fan (21) to perform the cleaning operation for a cleaning time interval, the duration of which is dependent on the detected temperature (T).
