[Keynote Address] MBD Guaranteed for Compatibility and Distribution by International Standard: General Remarks
-Support Technology for Digital Validation and Carbon Footprint-

Toshiji Kato (Doshisha University)･Kimitoshi Tsuji (Digital Twins)･Masahiro Okamura (JSOL)

To realize MBD including digital validation and visualization of carbon footprint (CFP) practically, model development and distribution systems that ensure compatibility are important and they need a standard. The investigating committee on the development & distribution of models by the international standard description of JSAE has investigated such a system mainly based on IEC61691-1 and IEC61691-6 (VHDL-AMS) and has built a cloud computing environment. This presentation aims to make MBD a support technology for further innovation through collaboration between different organizations.

Trajectory of the Activities of the Model-Based Development Technology Sector Committee Based on international Standard Description

Junichi Ichihara (AZAPA)

Model-Based Development Technology Committee with International Standard Descriptions has been working for the past 10 years. This report looks back on our activities to date and describes what kind of deliverables we have produced.

Initiatives for Virtual Testing using Digital Twins and Digital Authentication using it
-Comprehensive CO2 Reduction and New Manufacturing System-

Kimitoshi Tsuji (Digital Twins)･Toshiji Kato (Doshisha University)･Tsunehiro Saito (AGC)･Masahiro Okamura (JSOL)

Digital data distribution in cyberspace is becoming the backbone of industry due to its overwhelming convenience, and its reliability has become even more important than physical data. Certification through physical testing, which ensures reliability in manufacturing, is reaching its limits due to reproducibility and the diversity of conditions. Therefore, in this paper, we discuss certification through virtual testing and its applicability to comprehensive CO₂ reduction, etc.

Study and Proposal on OCC for Automotive Glass using EV Model (First Report)

Tsunehiro Saito (AGC)･Kimitoshi Tsuji (Digital Twins)

OCC (Off-Cycle Credit) is an important credit regulation for CO₂. Automotive glass credits have a high value in the U.S. OCC list, but this value is calculated for parking based on Tts (ISO13837) and does not take driving into account. In the first report, we report the results of OCC study that takes driving into account using EV model.

VHDL-AMS Modeling in CAN FD Network Validation

Kan Yamagishi･Makoto Mizuno･Naoto Sakurazawa (Myway Plus)

In the design of in-vehicle networks, simulation with VHDL-AMS models, which can handle both digital and analog signals, is an effective approach to overcome problems in the early stages of development. Here we show an actual example of creating a VHDL-AMS testbench for the high frequency CAN FD.
