Body Leveling Control Model Establishment and Experiment Analysis

Highlights The vehicle body leveling control model based on tire stiffness and wheel centroid displacement is established in this article. average pitch angle error 7.94%, the tilt 4.37%. algorithm developed can be applied to automatic of hilly tractors cars. Abstract . system core part attitude mountain tractor. It calculates posture real-time according makes corresponding strategies. accuracy directly affects accuracy. This article proposes mass displacement. slope road surface excitation information collected field, data processed appropriately. accurate obtained. input simulation data. However, acceleration signal. Thus, signal converted through frequency domain integration method. comparison between calculated calculation results experimentally acquired indicates that Accordingly, compatible with experimental accurately output develop tone.
