PROBLEM TO BE SOLVED: To provide an intake door controller capable of certainly preventing introduction of exhaust gas into the cabin by determining an environment outside a vehicle upon introduction of outside air. SOLUTION: The intake door controller comprises a stereoscopic camera for picking up a vehicle front image, a detecting means of a precedent vehicle travel state for detecting the travel state of the precedent vehicle based on the picked up image of the stereoscopic camera, and an exhaust gas estimating means for estimating distribution concentration of exhaust gas based on the detected travel state of the precedent vehicle. An intake door control means, when it is determined that the estimated distribution concentration of exhaust gas is high, is changed into inside air circulation. COPYRIGHT: (C)2005,JPO&NCIPI
