Abstract

The number of electronic control systems applied in vehicles has increased dramatically over
the years. This trend will only continue with the introduction of novel technologies such as
advanced driver assistance systems (ADAS). To save cable weight and costs in-vehicle control
systems often use shared communication networks. With the increasing use of in-vehicle
control systems the scheduling of these networks becomes a serious challenge.

In this master thesis a new event-triggered approach for the scheduling of networked control
systems (NCSs) using timed game automata (TGA) is considered. This new approach
yields some potential benefits over existing communication protocols and has already been
implemented successfully on two-dimensional linear time-invariant (LTI) systems. To obtain
the control system TGA for this scheduling approach the NCSs have to be abstracted. The
control system abstraction method that is used has to be modified in order to be able to
handle higher dimensional systems as well, and that is exactly the focus of this master thesis.
The abstraction method is extended and applied to three-dimensional and four-dimensional
in-vehicle LTI control systems. The outcomes are checked using simulations which show that
the applied abstraction method works.
