PROBLEM TO BE SOLVED: To rapidly and accurately judge whether the collision form of a vehicle is an oblique collision. SOLUTION: A lateral occupancy rate S is computed on the basis of time integrated values VL, VR from the judgment start time is of deceleration GL, GR detected by front sensors installed on the front right and left sides of the vehicle, up to the present time t (steps S100-A108). A lateral phase angleθis computed from the deceleration GL, GR (step S110). Thresholds S1, S2, S3 set corresponding to the lateral phase angle on the basis of a collision experiment or the like are led out from the computed lateral phase angleθ(step S112). Whether the collision form of the vehicle is an oblique collision is judged by comparing the absolute value of the lateral occupancy rate S with the led-out thresholds S1, S2, S3, and a collision angleαin the oblique collision is judged (steps S114-S128).
