Title:
VEHICLE BODY ATTITUDE ADJUSTMENT METHOD AND VEHICLE BODY ATTITUDE ADJUSTMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/029762
Kind Code:
A1
Abstract:
A vehicle body attitude adjustment method and a vehicle body attitude adjustment system, comprising: the displacement measurement value of a vehicle body, the angle measurement value of the vehicle body, and the acceleration measurement value of the vehicle body are respectively obtained; a control module calculates the displacement conversion compensation amount of the vehicle body according to the displacement measurement value, calculates the angle conversion compensation amount of the vehicle body according to the angle measurement value, and calculates the acceleration conversion compensation amount of the vehicle body according to the acceleration measurement value; the control module performs vehicle body attitude adjustment determination according to the displacement conversion compensation amount, the angle conversion compensation amount, and the acceleration conversion compensation amount, outputs decoupling and distribution, and determines the actual overall compensation amount of the vehicle body, wherein compensation to be performed by the whole vehicle needs to be converted into the compensation motion of a whole specific actuator; and the control module controls, according to the actual overall compensation amount, a vertical damping actuator, a transverse damping actuator, and a longitudinal damping actuator to output the compensation motion, and respectively performs compensation control on the vehicle in the vertical direction, the transverse direction, and the longitudinal direction, thereby improving the comfort of passing through a curved road section.
