Study on Orchard Vehicle Motion Stability Control System

摘要

Abstract: This paper focuses on tipover problem of orchard vehicle, establishes vehicle dynamic model with 7 degrees of freedom (DOF), proposes a vehicle motion stability control method based on real-time adjustment of vehicle posture parameters and relies on vehicle scale model motion stability control test. Analysis of test result shows that vehicle motion stability control model mentioned above can effectively prevent orchard vehicle tipover accidents. When vehicle encounters tipover accident, angles such as pitching angle vary rapidly. In anti-tipover control process, pitching and rolling angle have greater influence on vehicle motion stability. If K p and K d are adjusted properly, good vehicle motion stability control effect is acquired.
