WebThis work introduces a novel linearization of a brush tire model that is afﬁne, time-varying, and effective at any speed. We incorporate this tire model into a convex MPC formulation for lateral control on a low friction surface. Experimental results on an automated Volkswagen Golf GTI demonstrate effective steering control for path tracking ... WebThis phenomenon can not be explained with the simple tire brush model that has been employed thus far. FIGURE 3.18 . Combined slip side force and moment vs longitudinal force characteristics measured at two values of the slip angle for a 7.60–15 tire on a dry flat surface (from Nordeen and Cortese 1963).
