Abstract:
1. A collision detecting device for a vehicle comprising: a chamber member providing a space; a pressure sensor for detecting a pressure inside the space, and connected to the chamber member; a determination means for determining collision of an object with the vehicle based on the pressure of the space detected by the pressure sensor; a bumper absorber for absorbing an impact generated by the collision; a temperature sensor disposed around the chamber member or the bumper absorber to detect a temperature thereof, wherein the temperature sensor is located outside the chamber member and is disposed to a rear side of the bumper absorber; and a bumper reinforcement, wherein the bumper reinforcement is arranged at a rear side of the chamber member and the bumper absorber, and wherein the temperature sensor is arranged on a bottom of the bumper reinforcement, wherein the determination means corrects the detected pressure based on the temperature detected by the temperature sensor so as to be decreased when the detected temperature is higher than a predetermined upper limit temperature and so as to be increased when the detected temperature is lower than a predetermined lower limit temperature, and wherein the collision is determined based on the corrected pressure.
