For the whole project duration, the performed works and achieved results are as follows.
1) The first reporting period has covered:
- Elaboration of detailed architecture of experimental and testing systems to be included into the connected XIL environments. The architecture has been mapped to four Use Cases for designing (i) brake blending, (ii) ride blending, (iii) integrated chassis control, and (iv) fail-safe control.
- Introduction of the specific communication layer enabling connectivity between testing platforms situated by the project partners in different countries.
- Methodology of design, validation, verification and certification of safety-critical electric vehicle systems
- A set of real-time models and controllers for the Use Cases.
2) The second reporting period has covered:
- Elaboration of the Machine Learning methodology to build ROMs of the main electric vehicle components from the initial Full Order Models.
- High Confidence Models representing advanced versions of the ROMs, which are updated by the experimental data and enable the model adaptation to uncertain and variable factors.
- Preparation, launching and functional proof of the distributed local XIL test environment on the facilities of Technische Universität Ilmenau.
- Building and proof of several distributed remote XIL test environments conencting test facilities of the consortium participants at different geographical locations.
- Studies on the brake blending control, including elaboration of a set of recommendations regarding the consideration of thermal processes and methodology for regenerative braking tests.
- Studies on the ride blending and the integrated chassis control demonstrating that the developed remote XIL environment satisfies the real-time requirements by developing and testing highly complex controllers of electric vehicle systems.
- Fail-safe studies for the cases of communication failure, in-wheel motor short circuit, and torque inversion.
Based on the obtained outcomes, the project has produced a number of exploitable results as (i) shared and distributed XIL test methodology with a family of fully scalable demonstrators, and (ii) new / improved electric vehicle systems and functions validated through four Use Cases.
