摘　　要：建立了适用于汽车稳定性分析的人-车闭环系统整车动力学模型,提出了保证质心侧偏角为零的前馈和单神经元两种DYC控制策略。通过对这两种控制策略的低附着双移线道路仿真,对比分析了两种不同控制策略的控制效果。仿真结果表明:单神经元DYC控制策略能更有效地控制汽车运动状态,提高汽车纵向及侧向稳定性。A vehicle dynamic model was established for the human vehicle close-loop system to analyze the vehicle stability. Two direct yaw moment control（DYC） strategies, i. e., the feed-forward and single neuron PID control strategies were proposed to ensure the zero sideslip angle of the mass center. Through the simulation at low adhesion roads with double lane change, the two control strategies were compared. The seiulation results show that the single neuron DYC control strategy can more effectively control the wheel and vehicle motion, improve the lateral and longitudinal stability of the vehicle.
