摘 要：為研究大型车辆在复杂山区道路中的行驶安全性，通过Trucksim构建出了人-车-路耦合的仿真试验场景，针对两条实际山区道路车辆的行驶安全性进行分析。结果表明：在复杂山区道路中，由于弯道较多，车速和载荷是侧翻的主要影响因素，当大型车辆的行驶车速位于50km/h-60km/h的速度区间时，其横向载荷转移率会陡增至侧翻阈值，即接近于1;当路段为雨雪路面（附着系数为0.4）时，大型车辆在小半径弯道等危险路段极易发生侧滑。

Abstract：To study the driving safety of large vehicles on roads in complex mountainous areas， a simulation test scenario of human vehicle road coupling is constructed by using Trucksim， and the driving safety of vehicles on two actual mountainous roads is analyzed. The results show that， in the complex mountain road， as there are many curves， the speed and load are the main influencing factors of rollover. When the speed of large vehicles is in the speed range of 50km / h-60km / h， the lateral load transfer rate will increase sharply to the rollover threshold， that is， LTR is close to 1; when the road section is rainy and snowy （the adhesion coefficient is 0.4）， large vehicles are on the dangerous road such as small radius curve， and is easy to slide.
