摘　　要：给出了基于滑模变结构的AFS控制策略和直接横摆力矩加变滑移率联合控制的ESP控制策略。在分析两者控制性能的基础上提出了协调控制的一般原则。阐述了车辆状态识别算法并给出了具体的协调控制策略,最后通过3个典型工况的仿真计算验证了该协调控制策略的有效性。The control strategy of active front steering system （AFS） based on sliding mode theory and the control strategy of electronic stability program （ESP） （ combined control on both direct yaw moment and variable slip ratio） are presented. Based on the analysis on the control characteristics of both control strategies, a general principle for coordinated control is proposed. The vehicle state identification algorithm is described with the specific coordinated control strategy given. Simulations on three typical driving conditions verify the effectiveness of the coordinated control strategy.
