Abstract
A method for controlling a fan in a vehicle includes comparing the current temperature of at least a first device and a second device to multiple temperature ranges for each of said devices and determining on the basis of said comparisons whether fan speed should be changed, increasing fan speed to a maximum fan speed if at least one of the comparisons indicates that the maximum fan speed is desired, increasing fan speed to a reference fan speed if at least one of the comparisons indicates that an increase in fan speed less than the maximum fan speed is desired, and decreasing fan speed to a reference fan speed if the comparisons indicate that a decrease in fan speed is desired.
