A method and device for prevention of, together, toe sen in the case of road vehicles by means of a radargeraets

摘要

A radar-operated collision avoidance system for a roadway vehicle comprises a radar device for sensing the vehicle speed relative to an object and its distance thereto to decide whether the vehicle is approaching the object at a dangerously high speed. A minimum allowable distance represented by a digital code is stored in a memory location within an array of rows and columns and read out in response to a sensed vehicle speed relative to the roadway and to a sensed magnitude of steering movement. The minimum allowable distance is compared with the distance sensed by the radar to determine that the decision is valid only when the latter is smaller than the former.
