Vehicular object detection system, tracking control system, and vehicle control system
First Claim
1. A vehicular object detection system comprising:
- object detection means for detecting an object in front of a subject vehicle;
locus estimation means for estimating a travel locus of the subject vehicle;
detection area setting means for setting a predetermined detection area in front of the subject vehicle based on the travel locus of the subject vehicle;
and obstacle extraction means for extracting an obstacle based on a detection result of the object detection means and the detection area set by the detection area setting means;
wherein the vehicular object detection system further comprises acceleration/deceleration intention detection means for detecting an intention of an occupant to accelerate or decelerate; and
wherein the detection area setting means changes at least a width dimension of the predetermined detection area based on a detection result of the acceleration/deceleration intention detection means.

Abstract
An ACC system includes a radar device for detecting an object in front of a subject vehicle, locus estimator for estimating a travel locus of the subject vehicle, detection area setter for setting a predetermined detection area in front of the subject vehicle based on the travel locus of the subject vehicle, obstacle extractor for extracting a preceding vehicle based on a detection result of the radar device and the detection area, and acceleration/deceleration intention detector for detecting an intention of an occupant to accelerate or decelerate. Since the detection area setter increases the detection area for an obstacle when the acceleration/deceleration intention detector detects an intention of the occupant to decelerate, it is possible to reliably detect a cutting-in vehicle that cuts in front of the subject vehicle and to prevent the subject vehicle from coming into contact with the cutting-in vehicle, thus preventing the driver from feeling uncomfortable and ensuring reliable operation of the ACC system.
