摘　　要：从轮胎的侧偏性、悬架结构的受力特性等方面着手,并考虑道路横坡和超高的作用,建立了适用于道路安全研究的三自由度动力学模型.结合单点预瞄最优曲率模型和道路线形模型———SK模型,建立了考虑汽车动态响应的人-车-路闭环仿真模型,并提出求解方法.该模型在驾驶仿真和行车安全分析中得到了应用.Based on a consideration of road cross-sectional slope and superelevations, three Degrees of Freedom （3DOF） Dynamics Model is established through the study of dynamic characteristics of wheel tires and suspension structures of vehicles. The loop simulation model of driver-vehlcle-road system considering vehicle dynamic response is established on the basis of the 3DOF Model, SK model which is usually used in road alignment design and Optimal Preview Lateral Acceleration Model proposed by Guo Konghui, and the solution is alto proposed. The model is used in driving simulation and driving safety analysis.
