4th International Workshop on Critical Automotive Applications: Robustness & Safety


Providing computer-based services for vehicle functions has evolved to the point where a large majority of functions are realized by software. However, the need to provide safety and security in critical functions such as braking, steering, motor control, etc. requires an approach that can guarantee the continuous reliable operation of the functions. At the same time, there are a variety of functions that are less critical from the vehicle operation perspective that can be provided where safety and security are less critical. From a vehicle manufacturers point of view, providing both types of services in an economic and reliable manner is a real challenge. To meet this challenge, we consider the Rubus Tool Suit for the software development and a well-proven (in industrial use for over twenty years) and certified (according to ISO 26262) operating system Kernel for its execution. In addition, a user-friendly approach to model- and component-based development concept called the “software circuits” has provided an approach to meet the demands of both safety-critical deterministic and as well as non-safety critical non-deterministic services. In this paper, a brief history of the evolution of Rubus approach as well as an overview of the driving concepts used in providing the Rubus products are described.
