The invention discloses a vehicle steering moment estimation method for avoiding forward collision of a driver. The method comprises the following steps: constructing a vehicle lane changing motion model based on two-degree-of-freedom vehicle model parameters of a vehicle; setting constraint conditions of a vehicle lane changing motion model by simulating vehicle steering lane changing danger avoiding conditions; the vehicle lane changing motion model is calculated and solved, and yaw motion feature information of the vehicle is obtained; the yaw velocity of the vehicle and a yaw velocity time response curve are calculated according to the yaw motion feature information; calculating the yaw velocity based on a numerical integration method to obtain course angle information of the vehicle; according to the course angle information, the latest time of vehicle lane changing risk avoiding is obtained; therefore, the automatic emergency braking system of the vehicle can more accurately determine the moment of collision alarm or emergency braking implementation, the adaptability of the automatic emergency braking system of the vehicle to different driving scenes and driving requirements is enhanced, and the efficiency of the automatic emergency braking system and the safety of the vehicle are improved.

    本发明公开了一种驾驶员避免前向碰撞的车辆转向时刻预估方法,包括:基于车辆的二自由度车辆模型参数构建车辆变道运动模型;通过模拟车辆转向变道避险情形,设置车辆变道运动模型的约束条件;对车辆变道运动模型进行计算求解,获得车辆的横摆运动特征信息;根据横摆运动特征信息计算车辆的横摆角速度,以及横摆角速度时间响应曲线;基于数值积分法对横摆角速度进行计算,获得车辆的航向角信息;根据航向角信息获取车辆变道避险的最晚时刻;从而使得车辆自动紧急制动系统更加精准地确定碰撞报警或实施紧急制动的时刻,增强车辆自动紧急制动系统对不同驾驶场景和驾驶需求的适应性,提高自动紧急制动系统的效率以及车辆的安全性。
