emTrace: Extended model-based trace analysis
Quality assurance for interconnected mechatronic vehicle systems is a key issue in the German automobile industry. Rising demands on security and comfort, an increasing number of variants as well as a continuously growing complexity of hardware and software open up new problems for ensuring reliability and complying with legal requirements throughout the entire vehicle lifecycle.
The currently used on-board power supplies are interconnected reactive real-time systems, where complex functions are distributed over multiple control units. Due to the missing determinism in the overall system, even with extensive automated tests and ECU-internal diagnostic functions, not all fault mechanisms can be revealed or excluded.
A possibility to increase the test depth is runtime monitoring of the systems and subsequent evaluation of the recorded data (trace analysis).
Goal of this project is to substantially increase the effectiveness of trace analyses through extensive improvements in the areas expressiveness, analysis performance as well as user interaction and user support. For the first time, the following key concepts shall be adapted and implemented: model-driven design, parallelization and distribution as well as visual analysis. By the activities planned, trace analysis shall be extended to an expressive, performant and user-friendly standard tool for quality assurance.
Perspectives
After project completion, the algorithms and methods developed shall be incorporated into the existing tools of the project partners, for example the test automation environment ECU-TEST and the analysis framework TRACE-CHECK.
