Automotive system design: today and tomorrow

No other technology has enhanced the functionality of cars in the last few years like information- and communication-technologies. Electronic based systems provide the driver with a maximum of security, comfort, information and entertainment. Such electronic systems are specified by the car manufacturer and produced by the supplier. A model-based specification allows a detailed information interchange between these partners and limits mis-understandings. Today, models of such systems are developed by a structured analysis process. The desired function for one control unit is hierarchically divided, until the behaviour can be described by a state machine. Tomorrows electronic car systems provide enhanced functionality, are networked and interact with each other and external services. Designing such systems requires a powerful way to structure, describe and reuse the components of the car and the surrounding environment.
