during abusive driving manoeuvres, such as a kerb strike event. Impulsive suspension loads are applied to tyre and
suspension elements under such conditions. In particular, the aim is to specifically study the reactions of jounce bumper–
rebound stop and tyre characteristics. For this purpose, a vehicle in-plane pitch dynamics model with 7 degrees of
freedom suffices. Non-linear and hysteretic characteristics of the bump-stop elements are included through a new
parametric map concept, based on displacement and velocity-dependent hysteresis. Furthermore, a static tyre model
is described, tailored to predict the radial stiffness against penetration of an edge with a flat-type rigid body geometry.
The tyre model is derived on the basis of classical membrane theory and represented in terms of only a few input
parameters. Model validation is supported through experiments at both component and system levels.
