VEHICULAR COLLISION JUDGING DEVICE

Japanese Patent JP3876110

B2

PROBLEM TO BE SOLVED: To surely judge a collision in a short time.
SOLUTION: This vehicular collision judging device 10 comprises a central processing part 11 having a central acceleration sensor 21C of an almost central part of a vehicle, a right side processing part 12 having a right side acceleration sensor 21R of one side part, a left side processing part 13 having a left side acceleration sensor 21L of the other side part, a difference operation part 14 and a collision judging part 15. The difference operation part 14 calculates a difference ΔVR between a central section integral value VC to a central acceleration signal GC in the central processing part 11 and a right side section integral value VR to a right side acceleration signal GR in the right side processing part 12 and a difference ΔVL between the central section integral value VC and a left side section integral value VL to a left side acceleration signal GR in the left side processing part 13. The collision judging part 15 judges the collision on the basis of the respective acceleration signals GC, GR and GL, the respective section integral values VC, VR and VL and the respective differences ΔVR and ΔVL.
