The invention provides a driving assistance system and method based on automobile data recorder multiplexing, and the system comprises an automobile data recorder which is used for obtaining a front road image through a camera, and transmitting the image to a recorder host; the front millimeter wave radar is used for transmitting and receiving a radar signal, acquiring data information by processing the radar signal, and sending the data information to the recorder host; the recorder host is used for receiving images sent by the automobile data recorder and data information sent by the front millimeter wave radar, carrying out data fusion on the images and the data information to obtain road condition information, and sending the road condition information to the drive-by-wire chassis and the central control instrument through a CAN bus; the drive-by-wire chassis is used for braking the vehicle according to the road condition information sent by the recorder host; the central control instrument is used for displaying early warning information according to the road condition information sent by the recorder host. According to the technical scheme, the technical problems that in the prior art, two sets of system hosts with the automobile data recorder function and the ADAS function need to be installed at the same time, so that hardware cost is high, and arrangement is complex are solved.

    本发明提供一种基于行车记录仪复用的驾驶辅助系统及方法,所述系统包括:行车记录仪用于通过摄像头获取前方道路图像,并将图像发送至记录仪主机;前毫米波雷达用于发射并接收雷达信号,通过处理雷达信号,获取数据信息,并将数据信息发送至记录仪主机;记录仪主机用于接收行车记录仪发送的图像和前毫米波雷达发送的数据信息,将二者进行数据融合,获得路况信息,通过CAN总线将路况信息发送至线控底盘和中控仪表;线控底盘用于根据记录仪主机发送的路况信息进行车辆制动;中控仪表用于根据记录仪主机发送的路况信息显示预警信息。该技术方案解决现有技术需要同时安装设置行车记录仪功能和ADAS功能两套系统主机,从而导致硬件成本高,布置繁杂的技术问题。
