Multi-parameter input vehicle early warning control method and system based on millimeter-wave radar

The invention relates to a multi-parameter input vehicle early warning control method and system based on a millimeter-wave radar. The method comprises the following steps that a millimeter-wave radarsensor is used for acquiring basic running information of surrounding vehicles; judgment of the transverse running safety distance and the longitudinal running safety distance according to the detected transverse distance and longitudinal distance between the running vehicles is carried out, and when the distance is judged to be under the condition that L>SB or R>SB, the judgment result shows that the vehicles are in the safe running area; when the distance is judged to be under the condition that Smin
