Modeling embedded real-time systems consisting of different components with UML-RT leads to a design model using various diagrams. Sequence diagrams describe possible interactions between system components and may be annotated with specific real-time constraints. Statechart diagrams are used for describing each component's behavior. In order to be able to(More)
Hybrid Mechatronic Systems consisting of continuous and discrete system parts put special requirements on the specification and simulation techniques. Within this paper the electric windows of a car are used as a case study to evaluate our ideas in this area. For the specification of the continuous part (e.g. the motor) a description in DSL [8] or a block(More)
Highly sophisticated control systems are a driving force for innovation in automotive electronics. However, the integration of these systems within current and future vehicle projects is facing a complexity problem. Established methods of realizing such control systems need to be revised. A promising approach to address these problems is to use(More)
1 Introduction Today's embedded systems (ES) are characterized by more and more parallelism, distribution over different locations and hard real-time (RT) requirements. Consequently, the modern, structured design process has to deal with heterogeneous requirements and restrictions. Especially the integration of HW-design tasks with SW-design tasks and(More)
In automotive software and system design, explicit system and especially software models have only recently found their way into the development process. This paper will try to give an overview for what such models have so-far been used and which advantages they brought to vehicle manufacturers and suppliers. Another focus of this paper is the comparison(More)
$%675$&7 This paper describes a new active communication approach based on the C-LAB Pathfinder. The Pathfinder is a mobile communication robot, whose actions can be observed and controlled via internet. In contrast to usual communication devices that assume at least two communication partners or simply broadcast data like TV, we propose an active(More)

In this paper we describe a methodology and accompanied tool support for the design of complex embedded real-time systems. In many application domains such real-time systems also appear to be het-erogenous, i.e. made up of diierent parts, each following various be-havioral characteristics. To consider not only behavioral aspects during system design but(More)
