The vehicular collision detection device (1) has: a bumper absorber (2) which is disposed on a bumper reinforcement (9) inside a bumper (7) of a vehicle; a detection tube member (3) which has a hollow part (3a) formed therein and is installed in a groove part (2a) formed in the bumper absorber; and pressure sensors (4L, 4R) for detecting the internal pressure of the hollow part. The device detects the occurrence of a collision of an object with the bumper on the basis of the pressure detection results. The pressure sensors comprise a left pressure sensor (4L) and a right pressure sensor (4R). The device is provided with: a peak value detection part (61, S11) for detecting peak values (P1L, P2L) of a first pressure waveform, which are detected by the left pressure sensor, and peak values (P1R, P2R) of a second pressure waveform, which are detected by the left pressure sensor; and a collision position estimation part (62, S13, S15, S16, S19, S20) for estimating a collision position of the object on the basis of the peak values of the first and second pressure waveforms. |
