AI Technical Summary

Technical Problem

Existing technologies are prone to misjudgment when detecting targets behind vehicles using radar, especially in cases of diffuse reflection of radio waves, multipath propagation, and trailers, leading to a high risk of false detection.

Method used

By setting an entity determination area and a control object detection area within the radar detection area, the system determines whether the target object has an entity and distinguishes between them. The target object processing unit and the target object detection unit distinguish between real and fake targets. By combining tracking processing and determination steps, the reliability of target object identification is improved.

Benefits of technology

It effectively suppressed false detections of targets, improved the accuracy of radar detection, and ensured the reliability of the driver assistance system.

Abstract

The present invention addresses the problem of suppressing erroneous detection of a target object. A driving assistance device is provided with: a target processing unit that detects a moving body approaching from the rear of a host vehicle and performs driving assistance control, the target processing unit performing a process in which the target processing unit detects the moving body approaching from the rear of the host vehicle within a detection region of a radar that detects the moving body approaching from the rear of the host vehicle; setting an entity determination region separated from a control object detection region of the driving assistance control by a predetermined distance from the radar; a determination unit that determines that the target object is a moving object having an entity when the movement trajectory of the target object detected by the radar exists in the entity determination area, and uses the target object as a driving assistance control object; and determining that the target object is not a physical moving object and does not serve as the driving assistance control object when the movement trajectory of the target object detected by the radar does not exist in the physical determination area.
