Obstacle detecting apparatus and vehicle occupant protecting device using the same

摘要

An obstacle detecting apparatus which detects the distance between an obstacle and a vehicle by two distance measuring sensors, comprising collision angle calculating device in which a plurality of positions of the obstacle is calculated by way of triangulation on the basis of the distance information from the two distance measuring sensors, and a collision angle, which is formed between the obstacle and the vehicle, is calculated by the locus of the obstacle which is calculated by the calculated plurality of positions of the obstacle.
