Abstract: An outer panel and an inner panel of a vehicle door form a closed sealing chamber. A pressure sensor is attached to the inner panel to detect a pressure within the closed sealing chamber. The pressure sensor detects an increase in pressure caused by constriction of the closed sealing chamber when a collision occurs to a vehicle door. The in-vehicle speaker supplies a sound wave into the closed sealing chamber and detects, as an inspection pressure, a pressure in the closed sealing chamber when the sound wave is supplied. In an initial state of a vehicle, the inspection pressure is compared with an initial pressure threshold value, which is set based on a pressure in the closed sealing chamber generated when the sound wave is supplied. When the inspection pressure is equal to or lower than the initial pressure threshold value, it is detected that the air-tightness of the closed sealing chamber is lowered.

Abstract: A side collision detection device for a vehicle includes a hollow detection tube member, a pressure sensor, and a control device. The detection tube member is arranged in a door of the vehicle. The door includes a rigid member that is provided to extend in a front-rear direction of the vehicle. The detection tube member is arranged along an outer surface of the rigid member in a width direction of the vehicle. The pressure sensor detects a pressure in the detection tube member. The control device detects a collision of an object with the door based on a result of the detection of the pressure by the pressure sensor.
