为提高车辆的主动安全性和操纵稳定性,在介绍汽车稳定性控制系统分层体系结构的基础上,针对汽车侧向、横摆及侧倾动力学的耦合问题,提出了一种采用线性矩阵不等式方法的横摆与侧倾稳定的最优鲁棒控制策略,通过差动制动与主动悬架系统实现了横摆稳定与侧翻预防功能.并在CarSim与Matlab/Simulink环境下进行了仿真试验,结果表明横摆与侧倾最优控制策略对车辆横摆稳定性控制具有良好的作用.
In order to improve the active safety and steering stability of the vehicle, based on the introduction of the hierarchical architecture of the automotive stability control system, aiming at the coupling problem of the vehicle lateral, yaw and roll kinematics, a linear matrix inequality Method of yaw stability and roll stability of the optimal robust control strategy through the differential braking and active suspension system to achieve the yaw stability and rollover prevention function.And CarSim and Matlab / Simulink environment simulation test The results show that the optimal control strategy of yaw and roll has a good effect on the vehicle yaw stability control.
