This paper deals with modelling dynamic hybrid systems. Aim is to introduce a modelling approach which incorporates a modelling environment for contact models. This incorporation can be achieved by introducing so-called moving
guard sets for the model definition of dynamic hybrid systems. Based on the setup of a dynamic hybrid system using hybrid automata, the mathematical model description will be extended accordingly. A short discussion of
the model extension presenting possible applications. Furthermore, we will demonstrate the extended approach and its applicability for dynamic contact models in form of a case study using pendulum systems. The contribution
will present a possibility to bring DHS closer to entity based simulation models, which describe contact models on the basis of an individual set of rules for each involved entity. In the conclusion and outlook, further
steps and investigations to classify this modelling approach will be presented.
