Abstract: A vehicle underbody structure includes a catalyst disposed in a front portion of an exhaust pipe; a cover member for covering the catalyst from above; and a heat insulator disposed inside a tunnel portion behind the catalyst and configured to cover the exhaust pipe from above. The heat insulator is disposed away from the tunnel portion by a predetermined gap in an up-down direction. A front portion of the heat insulator and a rear portion of the cover member are disposed in such a way as to overlap each other. A front end of the heat insulator is disposed on the upper side with respect to a rear end of the cover member.

Abstract: A grille shutter control device of a vehicle includes an encapsulation structure covering an engine, a grille shutter provided at an opening formed at a front wall portion of the encapsulation structure, an actuator configured to move the grille shutter to open/close the opening, and a controller configured to control the actuator. The controller determines whether or not heat damage occurs on a related component relating to the engine upon key OFF, closes the grille shutter upon key OFF in the case of determining that the heat damage will not occur, and opens the grille shutter upon key OFF in the case of determining that the heat damage will occur.
