A collision possibility determination device includes: a detection unit which detects at least one object which moves relatively with respect to a moving body; and a determination unit which determines a collision possibility of the moving body with the object. The determination unit defines a first factor and a second factor which are spaces between the body and the object in a travelling direction and in a width direction of the body respectively. The determination unit determines the possibility based on the two factors when the object is within a farther area from the body, and the possibility based on only the first factor when the object is within a nearer area from the body.

Collision possibility determination device

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.

Object detection apparatus for vehicle

The object-detection device for vehicle provides a transmission-and-reception device; a reflection point calculation device; a segment setting device; a median point calculation device; and a relative speed calculation device, wherein the relative speed calculation device eliminates a calculation result of the relative speed in the car width direction, with respect to the reflection points calculated based on the electromagnetic waves which are irradiated to the most downward direction in the specified angle in the vertical direction, in case that the number of difference between the reflection points in the current processing and the reflection points in the previous processing is equal to or greater than a predetermined number.
