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 greatly reduced, and the early warning precision is remarkably improved.
本发明公开了一种基于驾驶行为状态的前方碰撞预警控制方法及系统,涉及智能预警领域。该方法的步骤包括:通过底盘信号和若干与行车状态有关的功能信号来确定行车状态,每个行车状态对应一个预先设置的增益;根据每个行车状态的状态值和增益,确定预警反映时间;根据预警反映时间和强化距离碰撞时间进行前方碰撞预警。本发明在确定是否需要预警时,充分考虑的与驾驶员状态对应的行车状态的预警反映时间,之后基于不同行车状态的预警反映时间,针对性的确定是否需要预警,进而大幅度降低了误报概率,显著提高了预警精度。
