Design Patterns of Timed Automotive Systems
The functional complexity of hardware and software systems is growing exponentially. This demands an integration of system validation in the design phase to guarantee that a concrete implementation conforms to the modeled requirements. System validation process involves use of advanced systematic techniques and tools. In this report we present design patterns of timed automotive systems and a method for validating the real-time behavioral patterns of control intensive applications. The real-time behavioral patterns of embedded controllers are modeled using Statechart diagrams of Unified Modeling Language. Concrete implementation of the Statechart diagrams consists of active objects in Java programming language with synchronous communication. In the implementation using specified timed annotations, we validate the real-time constraints to be satisfied by embedded controllers. We shall illustrate the validation process with an example of a gear controller used in automobiles, and furthermore, provide an algorithmic solution.
