摘要： A roadside object present at the side of a subject vehicle travel path and a preceding vehicle at a speed equal to or greater than a predetermined speed are detected based on points derived by transmitting an electromagnetic beam forward of the subject vehicle and projecting reflection points obtained onto a two-dimensional plane, a determination is made when the preceding vehicle passes near the roadside object as to whether it moved toward the travel path within a predetermined time before and after the passage, and the roadside object is not determined to be the obstacle when it is determined to have moved toward the travel path, thereby preventing the roadside object from being misidentified as the obstacle owing to erroneous recognition of it having intruded into the travel path of the subject vehicle when detecting the object using an electromagnetic beam.
