Abstract: A system for vehicle climate control comprises a number of sensors probing the speed of the vehicle, the position of climate temperature unit and mode doors, the speed of the fan, ambient and interior temperature, and airflow setting. In a body controller, the probed data are correlated to look-up table values to keep the airflow volume constant and to decrease voltage applied to a fan motor when the speed of the vehicle increases. A method of practicing the climate control implemented in the system comprises a sequence of steps providing sensing a number of parameters, defining and storing in a controller memory a data characterizing relationship between the speed of the vehicle and the other parameters of the system, and correlating the sensed and stored data to maintain the airflow volume substantially constant.
