Abstract:
We investigate the dynamics of a simple two-wheel vehicle model after deviating from an unstable steady powerslide motion. For a model with brush tyre characteristics we observed, that for a range of constant driver inputs (front steering angle, driving torque) the motion converges to a periodic oscillation around a circular path with a very small radius. In this talk we investigate, how a modified tyre model with decreasing friction coefficient for large slip velocities influences the stability and domain of existence for these periodic motions.
