基于CANape/VBox的前碰撞预警系统安全距离报警策略研究

Research on Latent Warning Strategy of Forward Collision Warning System Based on CANape/VBox

前碰撞预警系统是高级驾驶辅助系统中的一个重要功能,可有效减少因驾驶者疲劳、注意力分散等原因导致的交通事故。本文介绍一种基于毫米波雷达的前碰撞预警系统,重点对其中的安全距离报警策略进行分析研究,并提出一种基于CANape和VBox的参数标定和系统测试方法。应用该方法对一款在研车型上进行了实车标定测试,结果表明本文提出的安全距离报警策略能兼顾安全性与舒适性。

The front collision warning system is an important function of the progressive driving assistance system,which can effectively reduce traffic accidents due to driver fatigue and distraction.This article introduces a forward collision warning system based on millimeter wave radar.Focusing on analysis of the safety distance alarm strategy,proposes a parameter calibration and system test method based on CANape and VBox.The method is applied to the real vehicle calibration test of a vehicle model under study,and the results show that the safety distance alarm strategy proposed in this paper can achieve both safety and comfort.
