The invention discloses a vehicle lateral collision early warning system and method based on information fusion. The collision early warning system comprises a signal acquisition module, a vehicle state estimation module, a vehicle track prediction module and a vehicle collision early warning module. The signal acquisition module detects the relative position of a target vehicle relative to the vehicle, and outputs the relative position as a measurement variable to the vehicle state estimation module; the vehicle track prediction module estimates the relative motion track of the vehicle as the input of the vehicle collision early warning module; the vehicle collision early warning module calculates the critical value of the square sum arithmetic square root of the transverse distance and the longitudinal distance of the target vehicle relative to the vehicle within the safe collision early warning time, and therefore whether the lateral collision risk exists or not is judged.
一种基于信息融合的车辆侧向碰撞预警系统及方法,其中碰撞预警系统包括信号采集模块、车辆状态估计模块、车辆轨迹预测模块和车辆碰撞预警模块;信号采集模块检测目标车辆相对本车的相对位置,作为量测变量输出给车辆状态估计模块;车辆轨迹预测模块进行车辆相对运动轨迹估计,作为车辆碰撞预警模块的输入;车辆碰撞预警模块计算安全碰撞预警时间内,目标车辆相对本车的横向距离和纵向距离的平方和算术平方根的临界值,从而判断是否存在侧向碰撞风险。
