Abstract

This paper considers personal mobility vehicles with lean mechanism. We performed an analysis of the influence of some sudden steering input on the tire contact performance with the roll motion by simulation analysis using multi-degree-of-freedom vehicle dynamics model for three type model (3 wheels and Rear Steering, 3 wheels and Front Steering, 4 Wheels and Front Steering). The results of the analysis showed the relationship between the dynamic response of roll motion with lean mechanism and two control method of the lean mechanism. Then We have proposed performance improvement methods by applying the closed loop lean control model and applying the unstable zero transfer function to the front wheel steering.
