In particular, critical X-by-wire functions require sophisticated redundancy solutions. As a result, the overall Electric/Electronic (E/E) architecture of a vehicle is threatened to become even more complex and costly compared to conventional cars. In order to endeavour steps towards reducing complexity and cost, the main idea of SafeAdapt is to develop novel architecture concepts based on the adaptation to address the needs of a new F/E architecture for FEVs regarding safety, reliability and cost-efficiency. This will reduce the complexity of the system and the interactions by generic, system-wide fault and adaptation handling. It also enables extended reliability despite failures, improvements of active safety and optimized resources. This is especially important for increasing reliability and efficiency regarding energy consumption, costs and design simplicity. SafeAdapt follows a holistic approach for building adaptable systems in safety-critical environments that comprises methods, tools, and building blocks for safe adaptation. This also includes certification support of safety-critical systems in the e-vehicle domain. The technical approach builds on a SafeAdapt Platform Core, encapsulating the basic adaptation mechanisms for re-allocating and updating functionalities in the networked, automotive control systems. This will be the basis for an interoperable and “ready for standardization” solution for adaptation and fault handling in AUTOSAR. The SafeAdapt approach also considers functional safety with respect to the ISO 26262 standard. SafeAdapt provides an integrated approach for engineering such adaptive, complex and safe systems, ranging from tool chain support, reference architectures, modelling of system design and networking, up to early validation and verification of appropriate platforms. For realistic validation of the adaptation and redundancy concepts, an actual vehicle prototype with different and partly redundant applications is developed. Contribution TTTech will interconnect the Siemens “RACE” platform with the Delphi “TMDP” platform by means of a dual lane Ethernet / TTEthernet connection. TTTech will provide the appropriate TTEthernet and Ethernet switches as well as the TTEthernet end systems. In addition TTTech targets to investigate a special redundancy management technique, where the (possible gracefully degraded) function hosted on a failed unit will be downloaded to another ECU from a repository. The process foresees to initialize the function on the new ECU after actuators and sensors were connected to it via a switched network. The time from failure detection to service newly established function availability will be determined. Furthermore, the parameters to optimize the performance and minimize the “downtime” will be analysed. This will complement the adaptation mechanism researched in the FP 7 Project DREAMS. TTTech expects to be in the position to provide first class reconfiguration behaviour upon completing these two projects. Funding This project was filed in the frame of the “Green Cars Initiative” a Public Private Partnership (PPP) within Framework 7, initiated by the European Commission and thus receives funding from this funding instrument under supervision of the European Union and under the grant agreement no 608945.
