摘　　要：本文描述了17自由度汽车全工况操纵与制动过程动力学模型的建模、仿真与验证。该模型考虑了侧风、有无防抱系统、高速、变车速、双移线转弯制动等各种极端工况。仿真结果与美国密执安大学的仿真结果十分吻合,证实了该算法与模型具有很好的精度。This paper describes the modeling, simulation and verification of a motor vehicle with independent suspension. The vehicle model with 17 DOFs is developed to investigate vehicle handling and stability, and is capable of simulating extreme driving maneuvers. The model includes steering wheel angles, braking pressure, with or without ABS, varying velocity, road roughness and steering while braking, as well as side wind velocity etc. The simulation results are highly precise as compared with reference one.
