A Common Software Architecture for Diesel and Gasoline Engine Control Systems of the New Generation EDC/ME(D)17

In the new generation of engine control systems EDC/ME(D)17 Robert Bosch GmbH presents the approach for a common software architecture for gasoline and diesel systems. Motivations for this development are our customers' requirements for an open system architecture, the unification of engine type independent functionality and future business models for Hard- and Software. The architecture design supports a clear identification of common software components for a Gasoline and Diesel Control System by using the CARTRONIC domain model as a comprehensive basis for structures and interfaces of the application layer. To support software exchange with customers on any code level, a XML-based standard document type definition (DTD) is proposed. The requests for future business models is addressed by a layered architecture with consequent encapsulation of control unit hardware, sensors and actuators. Finally, the common architecture is an important condition for dealing with the systems complexity and future requirements.
