Pedestrian-vehicle collision detecting apparatus
First Claim
Patent Images
1. A pedestrian collision detecting apparatus for a vehicle comprising:
- a collision duration determining circuit working to determine a collision duration for which an object is being hit by a vehicle after collision of the vehicle with the object;
a collision condition monitoring circuit working to monitor a change in number of locations of collisions of the vehicle with a plurality of contact points of the object in a lateral direction of the vehicle; and
a pedestrian-vehicle collision decision circuit working to decide that the object being hit by the vehicle is a pedestrian when the collision duration is smaller than a given threshold value and when the change in number of the locations of the collisions is detected by said collision condition monitoring circuit.

Abstract
A pedestrian collision detecting apparatus for motor vehicles is provided which works to distinguish between impacts with pedestrians and other sorts of impacts using a combination of a collision duration for which a sensor continues to sense a physical impact arising from collision with an object and a time-sequential change in locations of collisions of the vehicle with objects, thereby ensuring the reliability of detection of a pedestrian-vehicle collision and allowing the size and production costs of the apparatus to be minimized to improve the mountability of the apparatus in motor vehicles.
