TTTech in particular contributes to SAFE-E goals by providing a software layer allowing the use of AUTOSAR basic software components even in up to ASIL D level, highly safety-relevant applications.

The TTTech contributions support application developers to re-use existing and proven in the field, non-safety-relevant software building blocks in highly safety-relevant, up to ASIL D-compliant applications, reducing development time and cost as well as the risk due to reusing proven software elements. Furthermore, TTTech investigates advantages and disadvantages when using multicore ECUs versus single core ECUs.
A video, showing how their results were applied in a demonstrator motor test stand for e-vehicles, provides evidence of the function and innovation of the software safety layer integrated in the motor control and the safety ECU developed.
In addition, SAFE-E partners provide suitable abstraction and models (safety goals-, safety case- and architecture modelling, meta models, micro-controller models, model-based fault injection) also allowing for early validation of key properties. SAFE-E targets for new tools and integrating existing ones for designing project goal appropriate applications. SAFE-E looks for means of automatic code generation including safety functionality according to ISO 26262 as well as for extending meta models for variant management and, in addition, for multi-criteria design space exploration. The results further aim at broadening the functionality in modern vehicles w.r.t. safety-relevant applications (i.e. electronic breaks, electronic gear boxes, steering, drive train for e-vehicles, motor control for e-vehicles). The project also aims at compiling appropriate training material supporting immediate pick-up in the automotive industry.
Safe-E has received funding from the EUROSTARS programme under grant agreement n° 6095 and from the Austrian Ministry for Transport, Innovation and Technology under the funding programme “EUROSTARS”, grant agreement n° 832456 (Austrian Partner) and from the German Bundesministerium für Bildung und Forschung (German Partners).
