Title:
VEHICULAR COLLISION JUDGING DEVICE
Document Type and Number:
Japanese Patent JP3876112
Kind Code:
B2
Abstract:

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, a left side processing part 13 having a left side acceleration sensor 21L, a difference operation part 14 and a collision judging part 15. The difference operation part 14 calculates a difference ΔVR or ΔVL between a central section integral value VC to a central acceleration signal GC and a right side section integral value VR to a right side acceleration signal GR or a left side section integral value VL to a left side acceleration signal GL. The respective side processing parts 12 and 13 extract an acceleration component of a prescribed frequency band from the respective acceleration signals GR and GL to be integrated in a prescribed period to calculate respective reference data. The collision judging part 15 judges the collision on the basis of the respective reference data, the respective section integral values VC, VR and VL and the respective differences ΔVR and ΔVL.
