The invention discloses an early warning method for assisting automobile driving and a millimeter wave radar system. The early warning method comprises the following steps that echo signals reflected by a plurality of external vehicles on a road are obtained; the multiple echo signals are processed, and driving information parameters of the vehicle are determined according to the echo signals; and when the driving information parameter meets an alarm function starting condition and a target vehicle meets a preset early warning condition in an alarm area, an alarm instruction is generated. Echo signals reflected by a plurality of external vehicles and ground objects on a road are obtained, the echo signals are analyzed through a signal processing algorithm, driving information parameters of the vehicle are determined, the echo signals are analyzed, attributes of a plurality of external original points are recognized and filtered, and a moving target vehicle is obtained. And when the running speed of the vehicle meets the alarm function starting condition and the moving target vehicle is in the alarm area, an alarm instruction is generated. A safer guarantee is provided for a driver.
本发明公开一种辅助汽车驾驶的预警方法及毫米波雷达系统,所述预警方法包括以下步骤:获取道路上的多个外界车辆反射的回波信号;对多个所述回波信号进行处理,根据所述回波信号确定所述本车车辆的行驶信息参数;当所述行驶信息参数满足报警功能启动条件同时有目标车辆在报警区域内满足预设预警条件时,生成报警指令。本发明中获取道路上的多个外界车辆和地物反射的回波信号,通过信号处理算法对该回波信号解析,确定本车车辆的行驶信息参数,对回波信号解析对多个外界的原始点属性识别,过滤处理获得运动的目标车辆,当本车车辆行驶速度满足报警功能启动条件时同时有运动的目标车辆在报警区域内,生成报警指令。为驾驶者提供更加安全的保障。
