Abstract

A vehicle travel control system wherein a plurality of objects ahead of a subject vehicle are detected by a radar system. Data corresponding to the plurality of objects within a predetermined region is united into a target object corresponding to a large-sized vehicle. If one of the objects is in a region spaced forward a predetermined distance from a representative position of the target object, which is spaced leftwards in a direction toward at an estimated locus at a predetermined distance apart from a left end point of the representative position, which is spaced forward at a predetermined distance from the subject vehicle and which is included in the estimated locus of the subject vehicle, one of the objects is separated as a target object corresponding to a small-sized vehicle from the original target object to control the traveling of the subject vehicle relative to the small-sized vehicle within the estimated locus.

Claims18

Dependent claims

A travel control system for a vehicle, comprising:

a transmitting/receiving means for transmitting an electromagnetic wave toward a predetermined region in a traveling direction of a subject vehicle and for receiving a wave reflected from an object in the predetermined region;
an object's information calculating means for calculating a position of the object relative to the subject vehicle based on results of the wave transmission and reception by said transmitting/receiving means;
a uniting means for uniting a plurality of objects into one target object based on at least positions of the plurality of objects when said plurality of objects are detected within the predetermined region;
a locus estimating means for estimating a future travel locus of the subject vehicle;
a vehicle control means for controlling the traveling state of the subject vehicle in accordance with the positional relationship between said target object and the subject vehicle when the target object united by said uniting means is within the estimated locus;
and
a separating means for separating said one target object into different target objects within and outside the locus estimated for the subject vehicle by the locus estimating means when the plurality of objects united by said uniting means are within and outside the estimated locus of the subject vehicle.
