Model-Based Development of Damper Properties and Vehicle Dynamics Performance through Model Exchange between OEM and Supplier Peng Lu・Hiroshi Endo・Shuta Suzuki (Astemo)・Yukihiro Adachi・Shunsuke Iwamatsu・Toshikatsu Hoshi・Kazuo Mori・Mitsunori Makino (Toyota Motor) Model Based Development methods have been widely used in the automotive industry. The development of damper components, which traditionally relies on subjective evaluation like handling and ride comfort in an actual vehicle. However, damper MBD development is still considered difficult for subjective evaluation index and highly accurate vehicle model. To improve these by close model collaboration and use a detailed damper model and simulator from the early stages of development between OEMs and suppliers. We developed detailed damper models which can calculate real-time for simulator. Also, we studied to use OEM vehicle models for in-house damper development efficiently. |

Model-Based Development of Damper Properties and Vehicle Dynamics Performance through Model Exchange between OEM and Supplier Yukihiro Adachi・Shunsuke Iwamatsu・Toshikatsu Hoshi・Kazuo Mori・MItsunori Makino (Toyota Motor)・Hiroshi Endo・Peng Lu・Shuta Suzuki (Astemo) It is expected that model-based development, collaborated between suppliers and OEMs from the early development phase, can improve product quality and prevent development rework. In this study, we focused on dampers and created a co-simulation environment for evaluating vehicle dynamics performance, exchanging models between companies. Handling and ride comfort evaluations were performed using a driving simulator, and obtained results were consistent with actual vehicle tests and offline simulations. |

Synergies of Developing and Testing Battery Management Systems (BMS) in SIL and HIL Environments Katsuya Tsuzuki (dSPACE Japan)・Fabian Bronner・Thomas Paradowsk (dSPACE GmbH) This paper presents an architectural design for the V-ECU aimed at shifting the development and testing of BMS from HIL to SIL. The primary objective is to enable the reuse of tests for both HIL and SIL environments. This is achieved by virtualizing the communication between the BMC and the CSC, which typically utilize the SPI interface. By simulating SPI communication, the behavior of the ECU can be tested virtually, ensuring that existing tests remain unchanged. Additionally, SIL testing can be seamlessly integrated into a CI/CT pipeline, facilitating streamlined and cost-efficient development and testing of both new and existing BMS. |

Improving e-Axle System Development Efficiency through MBSE/MBD Integration and Generative AI (LLM) Application Masaru Katsuki・Kazunori Kawashima・Takuro Kawasumi (JATCO)・Jyunji Kashitani (Panasonic System Design)・Shota Sato (Lightblue) "As thermal management becomes increasingly critical in electric vehicles, improving the quality and efficiency of e-Axle system development, including thermal system considerations, has become a crucial challenge. This presentation reports on practical examples of design support through the implementation of MBSE, its data integration with MBD, and the application of knowledge graph conversion of MBSE models combined with generative AI (LLM) technology." |
