In recent years, the increase in wire harnesses due to the advancement of automotive technology has become a concern. Utilizing wireless technology is crucial for environmental and cost reasons. This paper proposes Interference Suppression Arbitration Control （ISAC） to address radio wave interference, a key challenge in achieving wireless implementation via UWB. ISAC significantly improves the impact of radio wave interference.

Software-Defined Vehicles (SDVs), which achieves flexible control of vehicles, require reconfiguration of network according to change for communications of the software. In this study, we implemented real-time and dynamic network configuration function as middleware on automotive-grade devices, supporting representative 3 SDV use-cases with change for communications such as addition of new software. The performance evaluation result is reported.

Cybersecurity development in accordance with ISO/SAE 21434 is required for compliance with UNR 155.
ISO/SAE 21434 requires vulnerability analysis to be conducted, but does not provide specific procedures.
In this study, we have defined a CC/CEM-based procedure of vulnerability analysis, and further investigated automation by applying tools. We have applied these development methods to the product design and confirmed the feasibility.
