The invention relates to the field of vehicle roll control, in particular to a vehicle roll motion optimization control method and system, a storage medium and a vehicle. If yes, a suspension rod system hard point adjusting mechanism is controlled to drive the vehicle roll center height to be increased to the optimal vehicle roll center height. Due to the fact that the height of the roll center of the vehicle is adjustable, when the vehicle runs linearly, the height of the roll center of the vehicle can be designed to be low, the elastic element also adopts a low-rigidity scheme, and good vibration filtering comfort can be obtained. When the vehicle turns, a target value is preset through the system, the controller outputs an instruction to the hard point adjusting mechanism, and the roll center height is increased during turning, so that the load of the elastic element with lower rigidity is reduced, the roll angle of the vehicle is prevented from being too large, and the stability is ensured to meet the requirement; therefore, the comfort and the stability of the vehicle during straight driving and the stability during turning are both considered.
本发明涉及车辆侧倾控制领域,特别涉及一种车辆侧倾运动优化控制方法、系统、存储介质及车辆,其包括:基于车辆行驶工况判断车辆是否在转弯;若是,则控制悬架杆系硬点调节机构驱动车辆侧倾中心高度提高至车辆最优侧倾中心高度。由于车辆侧倾中心高度可调,车辆直线行驶时,可以将车辆的侧倾中心高度设计的较低,且弹性元件也采用较低的刚度方案,可以获取良好的滤振舒适性;而在车辆过弯时,通过系统预设目标值,由控制器向硬点调节机构输出指令,实现转弯时的侧倾中心高度提高,从而降低较低刚度的弹性元件的负荷,避免车辆侧倾角过大,保证安定性满足要求,从而兼顾了车辆直线行驶时的舒适性、稳定性和转弯时的安定性。
