A METHOD FOR CONTROLLING AIR QUALITY CONTROL SYSTEM FOR CARS

摘要

The present invention discloses a method for controlling a device for interrupting inflow of noxious fumes for cars with a first sensor and a second sensor sensing noxious fumes emitted from diesel cars or gasoline cars, performing the control of a damper not only closing or opening to let airs flow into car automatically according to the degree of the outside contamination and environment purity sensed through said sensor but also interrupting inflow of the outside airs into car by checking changing rate of the density of noxious fumes for each time unit, moreover performing optimal damper control by controlling the damper twice through checking whether the density of the noxious fumes exceeds the pre- established fixed absolute value in case that the density of noxious fumes increases continuously from the minimum value, further performing the optimal damper control by designating the circumstance emitting the high density of noxious fumes like the case of bus to the bus mode separately.
