Front collision early warning control method and system based on driving behavior state

The invention discloses a front collision early warning control method and system based on a driving behavior state, and relates to the field of intelligent early warning. The method comprises the steps that the driving states are determined through a chassis signal and a plurality of function signals related to the driving states, and each driving state corresponds to a preset gain; according to the state value and the gain of each driving state, early warning reflection time is determined; and performing front collision early warning according to the early warning reflecting time and the reinforcing distance collision time. According to the method, when whether early warning is needed or not is determined, the early warning reflection time of the driving state corresponding to the driver state is fully considered, and then whether early warning is needed or not is determined in a targeted manner based on the early warning reflection time of different driving states, so that the false alarm probability is gr
