Development of All-In-One Virtual Application Process for Efficient R&H Performance Development Jinhee Lee (Hyundai Motor) In this paper, a new virtual application process called R&H All-In-One Application Process is proposed. This process is developed to achieve more efficient R&H performance development. This process consists of 3 sub-process. First one is the CarMaker model generating process based on CAT data that provides reliable vehicle model from SPMD and inertia database rapidly. Second process is the CarMaker design of experiment automation analysis process and model based benchmarking process. This process provides the environment for analyzing the effect of R&H performance on changes in the combination of the vehicle parameter sets and test conditions but also, contribution analysis through systematic separation method. The last one is the Handling/Steering feel test database with integrated analysis platform. Through proposed process, it is expected that engineers related R&H performance development can conduct efficient virtual activity above a certain level. |

Simultaneous Identification of Spring Constant and Torsional Friction in the Frequency Region Higher than the Resonance Frequency of a Two-Inertia Resonance System Tetsuya Yada・Toshimasa Miyazaki・Padron Juan (Nagaoka University of Technology)・Yoshihisa Hojo (Toyo Denki Seizo) In multi-inertia resonance systems, accurate parameter acquisition is important for proper modeling and vibration control. In this paper, we propose a method to simultaneously identify the spring constant and torsional friction in the frequency range higher than the resonance frequency of a two-inertia resonance system. The effectiveness of the proposed method is confirmed by simulation and experiments. |

Development of Drivability Sensory Evaluation with Machine Learning and Quantification of Knowledge Takafumi Asano・Kosuke Tsuchiya・Kenji Kashiwakura・Takuma Kawaguchi・Haruki Shimura・Ryosuke Atarashi・Takashi Kaneko・Ryoya Kanahori (SUBARU) The evaluation of the combination of complex driving operations and vehicle behavior by expert drivers is necessary to enhance drivability performance. In this study, an evaluation method using Machine Learning developed to reduce extensive testing efforts and share knowledge of experts. Furthermore, the method was using engine bench system. This utilization involved predicting acceleration from ECU data, conducting evaluations independent of the vehicle. |

AI-Powered Vehicle Concept Development Mario Oswald・Joerg Schlager (AVL List)・Kisu Lee・Sungho An (Hyundai Motor)・Stefan Kellner・Nathan De Kerpel (AVL List) This publication covers a comprehensive methodology based on AI (artificial intelligence) presenting a paradigm shift in the selection of the right technology for all vehicle systems. The overall goal is to not only meet but also balance vehicle-level targets, setting the stage for a more streamlined and efficient development process. The center of this innovative approach are multi-layered and cascaded neural networks, which act as powerful tools enabling precise and simultaneous prediction of vehicle attributes like energy efficiency, range, charging, performance, vehicle dynamics and driveability. Furthermore, these networks even provide insights for the optimization of geometric vehicle architecture and crash. |
