PROBLEM TO BE SOLVED: To improve collision/crash position discrimination performance at a time of discriminating a collision/crash position using a plurality of acceleration detectors. ! SOLUTION: If a collision/crash object such as a pedestrian collides/crashes against a vehicle bumper, then a bumper cover 32 starts greatly deforming at a direct hit position, an absorber 38 presses a pressure member 34, a pressure of a pressure chamber 40 changes, and pressure sensors 14A and 14B, therefore, detect the pressure. Furthermore, if a lower limit determination unit determines that the pressure exceeds a pressure threshold, a collision/crash position discrimination unit discriminates an arrangement position of an acceleration sensor corresponding to a maximum displacement of displacements detected by respective acceleration sensors 16A, 16B, and 16C as a collision/crash position. !
