Abstract
A device for detecting a collision of a vehicle with an obstacle includes an enclosed space positioned behind a front bumper cover. Deformation or displacement of the bumper cover due to a collision is transmitted to the enclosed space. Air pressure in the enclosed space and its temperature are measured by sensors and electrical signals representing the pressure and the temperature are fed to an electronic control unit that determines whether the enclosed space is hermetically closed or not based on the pressure and the temperature of the air in the enclosed space. If the enclosed space becomes non-hermetical due to a collision impact, the air therein leaks and the pressure therein becomes atmospheric pressure irrespective of the temperature of the air in the enclosed space. Therefore, the hermetical condition of the enclosed space is surely detected.
