摘　　要：针对车道偏离预警时间采用固定阈值时准确率低、适应性差等问题,提出考虑驾驶员特性的车道偏离动态预警模型。在识别驾驶员驾驶意图的基础上,基于车辆动力学原理,分析车辆从当前位置到车道边缘所需要的最小时间,建立车道偏离预警模型。考虑驾驶员的驾驶特性,基于模糊推理规则提出车辆偏离动态预警模型。试验表明:提出的预警模型能对不同类型驾驶员、不同驾驶意图进行准确报警,具有较好的自适应性。To solve the problem of low accuracy and adaptability of the traditional lane departure warn⁃ing time with a fixed threshold,a dynamic model considering the characteristics of drivers was proposed for lane departure warning system.Based on the recognized driving intention,the minimum time of driv⁃ing from the current position to the lane edge was analyzed by the principle of vehicle dynamics.Then,combing the threshold time and driving characteristics,the dynamic warning model of vehicle deviation was established with the fuzzy inference rules.The results show that the proposed dynamic warning model can accurately alarm for different drivers and driving intentions.It has a good adaptability.
