The invention discloses a road condition detection and early warning method and device. The method comprises the following steps: starting a millimeter wave radar; transmitting a millimeter wave signal to a free space through a millimeter wave radar, and receiving an echo signal reflected by a target; processing the echo signal, and obtaining a processing result; if the processing result shows that the danger coefficient value of the front road condition exceeds the preset threshold value, sending the processing result to an alarm system. By applying the method provided by the embodiment of the invention, the influence of low-visibility environments such as rain, snow, fog and the like can be avoided, the long-distance road condition can be pre-judged in the vehicle driving state, the driver is pre-warned in advance, and the occurrence of traffic accidents is prevented.

    本发明公开了一种路况检测及预警方法及装置。所述方法包括:启动毫米波雷达;通过毫米波雷达发射毫米波信号至自由空间,并接收目标反射的回波信号;对所述回波信号进行处理,并获得处理结果;若所述处理结果显示前方路况的危险系数值超过预设阈值,则将所述处理结果发送至报警系统。应用本发明实施例的方法,可以不受雨雪雾等能见度低的环境影响,能够在车辆行驶状态中预判较远距离的路况情况,并对驾驶员进行提前预警,防止交通事故的发生。
