Abstract

In this paper, effects of the rotating wheel gyro moments on vehicle handling dynamics were considered in a three degree-of-freedom model that roll motion coupled with plane motion. Transfer functions of yaw rate and roll angle to steering angle were formulated and the root loci varied by rotating wheel gyro moments were analyzed. Moreover, gyro effects of rotating wheels on step responses and frequency responses to steering inputs were explored by numerical simulation. Based on the theoretical analysis and the simulation results, it can be concluded that the gyro moments of rotating wheels have contributions which can't be ignored to the vehicle handling dynamics.
