System for sensing whether an object struck in a collision is a pedestrian

摘要

A collision protection system for protecting a pedestrian that uses a sensor that provides a width output signal that varies in relation to the width of an object contacting the vehicle. The sensor includes a resistive conductor that is shorted out by a conductive conductor of a portion of the length of the resistive conductor. A second sensor may be provided that provides an output only upon exceeding an impact threshold. Several sensors may be used to provide an indication of the location and width of the object contacted.
