摘要(Abstract)：

针对直接横摆力矩控制（DYC）过度介入导致轮胎磨损与滑移损失的问题，提出一种综合转矩协调和主动后轮转向（ARS）的底盘协同控制策略。该策略采用分层式架构设计：上层控制器使用带有高阶扰动补偿的自适应离散参考滑膜轨迹，处理车辆建模时忽略的非线性因素和外界不确定扰动，利用离散滑模预测控制（DSMPC）算法计算广义力和广义力矩；下层控制器根据质心侧偏角相平面失稳误差和横摆角速度跟踪误差，将上层控制器的控制量合理分配至ARS和DYC系统。通过CarSim/Simulink联合仿真，双移线工况下的验证结果表明：相较于原始DYC控制策略，所提出的策略在干燥路面和湿滑路面的轮胎纵向滑移损失分别降低41.65%和15.68%，在提高操纵稳定性的同时，能够有效削弱控制器抖振问题。
