摘　　要：为提高山区道路大型车辆的行驶安全性,构建人-车-路协同仿真系统,在3条复杂山区道路上开展代表性驾驶模式的大客车和重载货车虚拟行驶试验,根据仿真输出的车辆运动学/动力学响应参量和驾驶输入量,分别进行设计符合性、车辆通过性、运行速度协调性、行驶舒适性以及驾驶负荷度等5个方面的检验分析。结果表明:通过以上分析能确定危险位置的临界安全速度、超长货车通过急弯时的越出宽度和越出位置、不协调的线形单元以及行驶舒适度和驾驶负荷度较差的位置,进而可以实施靶向性的几何参数改进,增加山区公路与大型车辆之间的适应性,最终达到提高山区公路设计质量和安全性的目的。To improve the safety level of large vehicles on mountainous highways,a collaborative simulation system of driver-vehicle-road was developed.Then virtual tests on a bus and a heavy duty truck on three complex mountainous highways under typical driving patterns were conducted.On the basis of kinematics/dynamic response parameters from simulation output data of vehicles and driving input data,the design compliance,passing ability,operating speed coordination,driving comfort and driving workload were tested for analysis respectively.The results show that by the analysis,the critical safety speed at dangerous positions,the exceeding width and exceeding position for long freight vehicle passing sharp curves,inconsistent adjacent alignment elements of a highway can be determined,as well as driving comfort and heavy workload positions.Therefore,purposeful design improvement in geometry parameters can be done,the adaptability between mountainous highway design and large vehicles can be enhanced,and finally the design quality and driving safety on mountainous highways can be improved.
