Method for controlling ventilating system of motor vehicle, by controlling speed of blower or degree of opening of choke in intake air duct of ventilating system if e.g. vehicle speed, is below or above threshold

摘要

The method involves controlling the speed of the blower of a ventilating system, when the parameter e.g. vehicle speed, related to the stagnation pressure at the intake air duct of the system is within the minimum and threshold values. The degree of opening of the choke at the intake air duct is controlled when the parameter is within the threshold and maximum values.
