Specification of user groups:
Contractors of the CVSM from testing and certification fields, powertrain OEM manufacturers and suppliers of accessories having their own R&D activities, and engineering service/R&D companies. Key methodological approaches, key challenges, key equipment:
Methodological approaches: The outcomes stimulate the use of sophisticated combined methods of time-consuming optimization based on the virtual reality (simulation) and its continuous calibration by experiments. The high-reliable predictivity consists in this combined approach, which at the other side accelerates the development by testing virtual variants only. It must react to very fast progress in
engine and transmission concepts, electric components, available fuels and flexible control systems. New standards of vehicle distributed systems based on TDMA will enhance the cooperation between vehicle systems but they are more sensitive to communication problems. The required reliability can be reached by simulation and testing the response to different failures at all protocol layers. This process is decisive to implementation of X-by-Wire technologies (Steer-by-Wire, Brake-by- Wire, Park-by-Wire, etc.). The investigation of network reliability is addressed by this activity together with the detection of the failure in electric equipment and the prediction of future possible failures.
Formulation of algorithms for direct and indirect approach. Data acquisition in LabView environment. Calibration of code parameters using optimization. Finding inaccessible values by iterative co-simulation associated with experiments. Key challenges: Continuous calibration of simulation codes by inverse algorithms coupled to experiments. Determination of inaccessible values (unsteady temperatures, variable gas compositions, unsteady flow-rates in movable parts of machines, etc.) by iterative co-simulation aimed at the best fit of simulation results to measured ones. Predictive and adaptive control of an engine/powertrain based on non-linear system hierarchy and interaction with transport infrastructure. Vehicle control and power networks/buses, X-by-Wire systems, predictive diagnostics of vehicle electric systems.
