The paper proposes an integrated adaptive coordination technique for active front steering (AFS) and direct yaw moment control (DYC). The main contribution is to present an integrated multi-input multi-output (MIMO) adaptive control method to manage the variations of vehicle mass and tire-road friction coefficient as parameter uncertainties. The proposed integrated control strategy encompasses two: upper and lower control layers. At the upper control layer, there is a model reference adaptive controller responsible for generating additive steering angle and corrective yaw moment. The coordination between AFS and DYC is realized using a gain scheduling mechanism based on a stability index. At the lower control layer, the desired yaw moment is converted to the brake torque before being applied to the rear wheels. Three critical and important high-speed lane-change maneuvers are considered. The simulation results confirm that the proposed control structure can reduce the sideslip angle and lateral acceleration. Furthermore, the system tracking performance in terms of handling and stability in different maneuvers is improved.

集成模型参考自适应控制,可协调主动式前转向和直接横摆力矩控制。

本文提出了一种用于主动前转向(AFS)和直接偏航力矩控制(DYC)的集成自适应协调技术。主要贡献是提出一种集成的多输入多输出(MIMO)自适应控制方法,以管理车辆质量和轮胎-道路摩擦系数的变化作为参数不确定性。提议的集成控制策略包括两个:上控制层和下控制层。在上层控制层,有一个模型参考自适应控制器,负责生成附加转向角和校正偏航力矩。使用基于稳定性指标的增益调度机制可实现AFS和DYC之间的协调。在下控制层,所需的横摆力矩在施加到后轮之前转换为制动扭矩。考虑了三个关键和重要的高速换道操作。仿真结果证实了所提出的控制结构可以减小侧滑角和横向加速度。此外,就不同操纵的操纵性和稳定性而言,系统跟踪性能得到了改善。
