This paper proposes a new safety framework and platform for the functions of future electrical/electronic (E/E) systems. The framework aims to cope with the increasing complexity of the E/E systems, and to enhance their flexibility, but retain the safety properties and keep low engineering costs. A domain-specific meta-model is used to specify relevant aspects of the system such as component interface...
This paper presents a new approach for demonstrating whether safety-critical, hard real-time systems implement fault hypotheses correctly and timely. In the forefront are tests which non-intrusively and deterministically stimulate and monitor the system under test. The tests use a domain-specific language which can formalize logical truths on system properties derived from fault hypotheses. Test results...
The automotive domain is challenged by the increasing importance of Information Technology (IT) based functions. To show the possibilities of modern IT systems, a demonstrator car was developed in RACE (Robust and Reliant Automotive Computing Environment for Future eCars) based on a completely redesigned E/E architecture, which supports the integration of mixed-criticality components and offers features...
Over the past few years semi-autonomous driving functionality was introduced in the automotive market and this trend continues towards fully autonomous cars. While in autonomous vehicles, data from various types of sensors realize the new highly safety critical autonomous functionality, the already complex system architecture faces the challenge of designing highly reliable and safe autonomous driving...
It is currently difficult to provide advanced services with high quality when mobile users are roaming in a foreign network, since operators deliver services from platforms in their home networks. This paper presents a solution to support efficient access to services from a location close to the user. This is a key issue in the development of more flexible distributed service platforms, where service...
The delivery of mobile services is traditionally limited to the cellular operator's home domain, except for a small set of standardized services. Due to the centralized nature of service platforms, resource demanding services suffer from long delays if a user is accessing them when roaming. In this paper we describe an architecture that supports a dynamic, distributed service provisioning for mobile...
