高速公路汽车辅助驾驶安全换道模型

为解决高速公路行车危险状态下驾驶员有意识换道过程中发生的车辆碰撞等交通事故问题,在前期研究车道偏离预警的基础上.针对确立的典型换道场景,建立了更加符合实际的基于换道过程中车辆加速行为的安全换道模型,并借助Matlab软件开发的仿真程序对建立的模型进行了仿真分析。结果表明,本文建立的模型具有较好的实用性,可为进一步建立车辆安全换道辅助系统奠定基础。

Safety lane change model of vehicle assistant driving on highway

To deal with the problem of traffic accidents such as vehicle collision during the conscious lane change of the vehicle on the highway under dangerous conditions, a now safety lane change model was established on the basis of the previously studied and developed lane departure warning system. The model considered the typical lane change scenario and more actual behavior that most driver often accelerate their vehicles during the lane change process. A simulation program was developed to analyze the model performance based on the software Matlab 7.0. The established model was compared with the developed by California University and the result showed this model is more practical. It can be used to establish the vehicle assistant driving system for lane change.
