摘　　要：定义了疏于观察时间,分析计算前车的制动灯亮后,前后车辆在各个阶段行驶的距离,建立了汽车追尾的数学模型,得出结论:车辆行驶的速度、车间距离、疏于观察时间和驾驶员反应时间是造成汽车追尾的主要因素.MATLAB仿真结果与理论一致.提出了避免汽车追尾的措施.No observation time of the driver of the rear vehicle is defined.A mathematical model of rearend collisions is established,through the calculation of distances traveled by the front vehicle and the rear in different phases of the braking process after the brake lamp of the front vehicle lights.The model indicates that the main factors of rear-end collision are traveling speed,following distance,no observation time and driver reaction time.A simulation platform is built by MATLAB.The simulation results agree with the model.Two measures to avoid rear-end collision are proposed.

关 键 词：汽车追尾 车间距离 疏于观察时间 驾驶员反应时间
