汽车后视毫米波雷达安装角标定系统设计研究

A control logic design research of one rear flank radar system

文章论述了基于汽车后视毫米波雷达系统的安装角标定方案。该侧后雷达系统实现了盲区监测,换道辅助等功能。针对上述功能的实现,需要对雷达进行安装角标定,目标角度的测量是对确定目标相对于本车的车道位置、计算纵向车速进而计算碰撞时间等具有决定性的影响因素,对于报警结果产生直接影响,其测量的准确性尤为重要。论文从雷达测角理论分析,到实际现场方案验证,进行了详细的阐述。

This paper discusses the control logic of the rear flank radar system based on microwave radar. This rear flank radar system has realized the function of the blind spot detection, lane change merge assist, cross traffic alert, rear collision warning and passenger door open warning. For the above function, this paper describes the functional one by one and discusses the control logic design of the system. The content mainly includes open condition, alarm condition, alarm type and functional logic for each function of the system. At last, the paper reviews the progress of the functional alarm logic priority.
