<p>A cooling system for an automotive vehicle of the type having a radiator (18) through which a coolant fluid flows includes a fan motor for driving a fan (16) which moves air through the radiator; an alternator (14) for supplying an output voltage to the fan motor (16); and a voltage regulator (28) which selectively excites the alternator's field winding (26) in response to a control signal (41), determined on the basis of at least one operational parameter of the vehicle indicative of the cooling requirements of the engine which powers the vehicle to control the output voltage of the alternator (14), thereby controlling the speed of the fan motor (16).</p> |
