    • PROBLEM TO BE SOLVED: To provide a collision detection device for a vehicle, improving accuracy of an operation level of a pedestrian protection device by suppressing a change of F-P characteristics of a chamber space due to the difference of temperatures. SOLUTION: This collision detection device is equipped with: a chamber member 7 disposed in a front surface of a bumper reinforcement 4 in a vehicle bumper 2 and formed with a chamber space 7a therein; a pressure sensor 8 for detecting pressure in the chamber space 7a; and an absorber 6 arranged in the front surface of the bumper reinforcement 4, and constituted to detect a collision with the vehicle bumper 2, based on a detection result of the pressure sensor 8. In the chamber member 7, a load-pressure change characteristic being a relation between received load and a pressure change of the chamber space 7a has temperature characteristics for canceling temperature characteristics of load-displacement characteristics the absorber 6 has.

    • PROBLEM TO BE SOLVED: To provide a collision detector capable of correctly determining a collision of an object with a vehicle by suppressing a chamber member from being nipped due to the deformation of a bumper absorber. SOLUTION: This pedestrian collision detector includes the chamber member 10, a pressure sensor 11, and the bumper absorber 13. The chamber member 10 forms a chamber 100. The pressure sensor 11 detects pressure in the chamber 100. The bumper absorber 13 absorbs an impact. The bumper absorber 13 is arranged to cover the periphery of the chamber member 10. A clearance 130 is formed over the whole area in a vehicle width direction between the chamber member 10 and the bumper absorber 13. Therefore, even if the bumper absorber 13 is deformed due to the collision of the object with the vehicle, the chamber member 10 is prevented from being nipped by the deformed bumper absorber 13. Accordingly, it is possible to correctly determine the collision of the object with the vehicle. COPYRIGHT: (C)2009,JPO&INPIT
