The invention relates to a commercial vehicle safe driving auxiliary system based on vision and millimeter wave radar fusion. The system comprises a forward-looking camera installed on a front windshield of a vehicle, a millimeter-wave radar installed on a front bumper of the vehicle, and a fusion controller installed in a cab of a vehicle head, wherein the forward-looking camera collects visual data in real time, the millimeter-wave radar collects spatial position data in real time and transmits the spatial position data to the fusion controller for processing, the fusion controller transmitsthe processing result to a vehicle brake control system, the vehicle brake control system activates a vehicle brake system, avoids or reduces vehicle collision through speed reduction, transmits datato an instrument desk through a CAN bus, carries out prompt and acousto-optic early warning of abnormal driving conditions in front of a vehicle, and is a closed-loop process of perception-operation-execution-feedback circulation. The system is simple in structure and easy to implement, can automatically monitor the road condition in front of the vehicle in real time, and has the function of automatically activating a brake system.
本发明涉及一种基于视觉和毫米波雷达融合的商用车安全驾驶辅助系统,包括安装在车辆前挡风玻璃上的前视摄像头、安装在车辆前保险杠上的毫米波雷达、安装在车头驾驶室的融合控制器,前视摄像头实时采集视觉数据、毫米波雷达实时采集空间位置数据并传输至融合控制器进行处理,融合控制器将处理结果传输给车辆制动控制系统,车辆制动控制系统激活车辆制动系统,通过降速来避免碰撞或减轻车辆碰撞,同时通过CAN总线传输数据至仪表台,对车辆前方异常行驶情况进行提示和声光预警,是一个“感知—运算—执行—反馈”循环的闭环过程。本系统结构简单,易于实现,可对车辆前方的路况进行实时自动监测,同时具备自动激活制动系统的功能。
