This invention discloses a method, system, and vehicle for adjusting body roll in crosswinds during oncoming traffic. The method acquires full-dimensional parameters and inputs them into a crosswind impact timing prediction model to predict the impact timing in advance. Based on this, it divides the adjustment into three stages: pre-tensioning, precise attitude control, and recovery, overcoming the inherent lag of existing passive feedback control's post-event intervention and achieving a leap from post-event compensation to pre-event control. The pre-tensioning stage uses a non-full pre-tensioning target value, and the recovery stage smoothly restores the vehicle according to the calibrated slope. This avoids the comfort degradation caused by existing on / off pre-adjustment technologies that apply full pre-tension throughout the entire process without a smooth recovery, effectively suppressing crosswind impact while significantly improving the driving experience. Differential adjustment of the damping / stiffness of the left and right suspensions is performed based on the bidirectional impact characteristics, overcoming the shortcomings of existing technologies that apply a one-size-fits-all approach and cannot differentiate adjustments based on the impact direction, resulting in a significant improvement in attitude control accuracy.

A dual-axis drive motor is simultaneously activated to precisely control the rope's deployment and retraction, achieving wind load balance through structural adjustment without significant tilting of the fuselage.
