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 req
