OBSTACLE DETECTION DEVICE AND OBSTACLE DETECTION SYSTEM

摘要

Objects relatively approaching a vehicle diagonally are detected, and at least relative distances of the detected objects with respect to the vehicle and relative speeds of the detected objects with respect to the vehicle are calculated. Using the relative distances of the objects and the relative speeds of the objects, estimated collision time lengths to collisions of the objects with the vehicle are calculated respectively. A predetermined number of the objects that are arranged in an ascending order of the estimated collision time lengths are selected, and pieces of detected information on the selected objects are output.
