摘　　要：为了分析全电动轮汽车加速转向工况对行驶稳定性的影响,建立了全电动轮汽车7自由度转向运动学模型,其中考虑了汽车在加速转向过程中载荷的转移、离心力以及轮胎侧偏角的影响。在Matlab/Simulink环境下建立了整车仿真分析模型,并得到Carsim参数化仿真软件验证。提出采用一个模糊PID控制器调节四个电动轮的转矩的控制策略,基本实现了全电动轮汽车转向加速过程中的操纵稳定性控制,可以为开展对全电动汽车动力学控制研究提供参考。On the basis of steering k^nematics, the dynamic model with 7 degree of freedom was established to analyze the influence on the handing characteristics, which was involved with the factors of load transfer, centrifugal force and slip angle of the t/re. A full vehicle simulation model was developed in Matlab/Simulink environment and was verified by Carsim software. A fuzzy-PID control strategy was proposed to regulate torque of each electric wheel and performed handling and stability control during vehicle accelerating steering, which can provide reference to the research on the control method of all motorized electric vehicle.
