Assuming that tire cornering force is given by the linear combination of tire dynamic load and slip angle in addition to it's steady state value at a constant radius circle turning, the following findings are summarized from the analysis of a half car model during cornering on uneven roads as follows: (1) It is made clear that bouncing reduction is effective mainly on side slip motion and also pitching reduction on yawing motion. (2) Simulations proposed in this paper shows the possibility of quantitative discussions for optimal control strategies of active chassis systems for improving lateral stability on uneven roads. (3) By the closed loop analysis with driver control, it can be proved that the control system integrated with both active suspension and rear wheel steering systems contributes to active safety more effectively than those individual systems.
