PROBLEM TO BE SOLVED: To perform accurate collision determination without any front clash sensor included.SOLUTION: A vehicle collision determination device includes vibration detection means for detecting high-frequency vibration generated in a vehicle longitudinal direction and low-frequency vibration of a bandwidth lower than the high-frequency vibration during collision, front collision determination means for determining whether to activate anti-front collision occupant protection device based on the detection result of the low-frequency vibration, safing determination means for determining whether to activate all occupant protection devices based on the detection result of the high-frequency vibration, rebound determination means for determining whether to activate anti-rebound occupant protection device based on the detection result of the low-frequency vibration and the detection result of acceleration generated in the width direction of a vehicle side part obtained from the outside, first activation means for activating the anti-front collision occupant protection device based on the determination results of the safing determination means and the front collision determination means, and second activation means for activating the anti-rebound occupant protection device based on the determination results of the safing determination means and the rebound determination means. |
