System Simulation in Automotive Industry

Abstract

System simulation is a part of the overall field of systems engineering and provides quantitative results to verify and validate the architecture and parameters of a system under development. In the meantime, system simulation is a wellestablished activity in the automotive development area and covers a broad range of applications over the whole development process from system architecture definition, component dimensioning up to virtual testing and calibration. In all of these steps, simulation helps the systems engineer find the best choice of system architectures, evaluate the component target characteristics, define the control logic and parameters, and support the individual tests. Thanks to system simulation, proper system function can be confirmed in early phases of development, which minimizes the number of cost-intensive development loops. In addition, verification and validation and calibration tasks can be frontloaded to reduce overall development time. This chapter focuses on the setup of different physical domain models and how they are linked together. The modeling approaches of the individual domains and simulation management are discussed.

Novel anode recirculation blower for PEM fuel cells

“…It is AVL's solution for multidisciplinary system simulation, which is designed for mobility concept analysis, subsystem design & layout, and virtual component integration. With different physical domains including gas thermodynamics, electro-chemistry, coolant/refrigerants and mechanical-& electrical-networks, being included in the model library, all relevant physical areas of a powertrain system are covered by AVL CRUISE TM M, which is shown by Knaus et al (2020). The fuel cell system is designed to provide a maximum power of P ≈ 100 kW and, subtracting the BoP consumption, 80 kW net power output.…”
