65 results about "Body roll" patented technology

On wheeled or tracked vehicles, body roll is the load transfer of a vehicle towards the outside of a turn. When a vehicle is fitted with a suspension package, it works to keep the wheels or tracks in contact with the road, providing grip for the driver of the vehicle to control its direction. This suspension is compliant to some degree, allowing the vehicle body, which sits upon the suspension, to lean in the direction of the perceived centrifugal force acting upon the car. Anti-roll bars are a part of the suspension specifically designed to address body roll.

A method, system and vehicle for adjusting crosswind tilt when meeting oncoming traffic.

PendingCN122300476ABody rollAttitude control
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.
