AI Technical Summary

Technical Problem

Existing collision avoidance systems face challenges in detecting vehicles outside the sensor's detection range and in managing the limited capacity of vehicle-to-vehicle communication, leading to potential delays in collision avoidance.

Method used

A collision avoidance system that integrates a perimeter monitoring system using sensors and an approaching vehicle notification system via vehicle-to-vehicle communication, with a detected vehicle comparison and judgment system to coordinate both, enhancing detection accuracy and reducing detection time by prioritizing image processing and communication based on vehicle information.

Benefits of technology

Improves the accuracy and speed of vehicle detection, enabling smooth collision avoidance by integrating sensor and communication systems to cover vehicles outside the detection range and manage communication effectively.

Abstract

To improve accuracy in detecting a vehicle requiring collision avoidance in a collision avoidance system.SOLUTION: A collision avoidance system 1 includes: a periphery monitoring system 2 for detecting an approaching vehicle with the use of a sensor; an approaching vehicle notification system 3 for performing communication with the other approaching vehicle by inter-vehicle communication; and a detected vehicle comparison and determination system 4 connected to the periphery monitoring system 2 and the approaching vehicle notification system 3, so as to determine a common vehicle detected by both of the periphery monitoring system 2 and the approaching vehicle notification system 3, and to control the periphery monitoring system 2 and the approaching vehicle notification system 3.SELECTED DRAWING: Figure 1
