摘　　要：将同向行驶两车的车速、驾驶人员状态、天气状况、道路状况等变量结合起来,运用运动学分析方法,建立了汽车防追尾安全距离的数学模型,并根据安全距离数学模型,给出自车现况安全与否的判断流程图。Combining variables such as speed, driver＇s state, weather state, road state of two trucks going in the same direction together, using the kinematics analytical method, the mathematical model of the safe distance in avoiding automobile rear-end collision is set up. According to the mathematical model of the safe distance, the flow diagram is educed for judge whether the car is safe from the current state or not.

关 键 词：安全距离 流程图 运动学分析 汽车防追尾
