Abstract:
A pedestrian collision protection system for a vehicle, comprising:a collision detecting element fixedly secured to a bumper of a vehicle for detecting a collision against a pedestrian; a collision site detecting element for detecting a position of a collision site in lateral directions of said vehicle; and a pedestrian protecting element provided in said vehicle for protecting said pedestrian from the collision according to a pedestrian collision site in said lateral directions at a collision against the pedestrian on the basis of outputs of said pedestrian collision detecting element and said pedestrian collision site detecting element, wherein said collision detecting element also functions as said collision site detecting element, and includes: a line sensor composed of a plurality of conductive lines which are separated from each other by a predetermined spacing to confront each other and come into contact with each other when a collision against the pedestrian occurs; and a detection circuit unit made to carry out the collision detection and the collision site detection on the basis of a variation of quantity of electricity related to an impedance between said plurality of conductive lines.
