Application Example of MBSE for HEV Fuel Efficiency Allocation Independent of System Configuration

Hironori Yumura･Takuya Machida (SUBARU)

During the initial planning stages for selecting HEV systems, fuel efficiency is a crucial metric. Predicting this performance through simulations is vital. However, the vast number of different system configurations, each requiring unique plant and control models, makes comprehensive simulation impractical due to the extensive workload. Therefore, in this paper, we introduce a case where the simulation model was simplified based on the inherent functions of HEVs, and target allocation was conducted.

Systematic Engineering Methods Enable Fast, Cost Efficient & Target-Oriented Development of Upcoming EV (Electric Vehicle) Generations

In the automotive market there is high pressure on development speed & cost. It must be ensured that under such boundary conditions all requirements are still met.

In this current transition phase in the automotive engineering world, (Model-based) systems engineering, (MB)SE is an enabler to handle the new complexity. It addresses the need for a new systematic, target focused efficient development process.

The paper will therefore cover beside MBSE itself, development topics like virtualization (integrated simulation) and the digitalization within the process such as digital twin and connected data, continuous traceability of development artefacts and monitoring of product maturity.
