STUDY ON A DYNAMICS MODEL FOR COACH ROLLOVER CONTROL

摘要

This paper presents a dynamics modeling methodology which can be used to establish a 3-DOF (degree of freedom) coach dynamics model for active roll stability control. The methodology is based on setting up a coordinate systems centered on roll center. The coach vehicle dynamics model including longitudinal,lateral,yaw and roll motions is established by applying this methodology. A comparison test is also made for validating this dynamics modeling methodology and the established vehicle model. So the model is able to provide a good foundation for early warning of coach passenger rollover.
