Significant Simulation Time Reduction by the Multi-rate Approach in CRUISE™ M
The simulation of typical CRUISE™ M applications as for instance hybrid, battery and fuel cell electric vehicle models requires the coupling of electric, mechanical, fluid and thermal networks. Each network is established by combining the physical equations and connection structure of elementary components and results in a differential algebraic equation (DAE). In order to speed up the simulation, a non-iterative multi-rate time integration co-simulation method for the system of coupled DAEs has been developed and released in CRUISE™ M 2019 R2.
MathConsult has been doing cooperative research in automotive simulation together with AVL since 2002.
