Object struck discrimination system and protection system

摘要

An object struck discrimination system 100 to be installed in a vehicle comprises an impact receiving member 120 for receiving an impact from an object struck which extends lengthwise along the width of the vehicle, a detection sensor 130 for detecting the moving speed and/or the acceleration of the impact receiving member 120 during a vehicle collision, and a control unit 160 for deriving the maximum moving speed and the maximum acceleration based on the information detected by the detection sensor 130 and discriminating the object struck based on the correlation between the maximum moving speed and the maximum acceleration.
