| Abstract(J) | SDVのOTA更新は型式認証関連機能を変えうるが，再評価をどれだけ仮想で消化できるかの手法は未確立．本研究は変更影響度分類と仮想証拠信頼性ティアからクレジット配分マトリクスを構成し，L3 ALKS（UN-R157）の60→95km/h ODD拡張に適用，仮想消化率と実車残存試験を導出する． Translation |
| Abstract(E) | Over-the-air (OTA) software updates can alter type-approval-relevant functions of software-defined vehicles, yet how much of the required re-assessment can be discharged virtually rather than physically remains under-specified. Simulation-credibility provisions for type approval (EU 2022/1426; NATM) and software-update management (UN-R156/SUMS, RXSWIN) exist separately, but no method connects them by accounting for virtual evidence reuse across an OTA change. This study proposes such a credit-allocation method, pairing change-impact classification with a virtual-evidence credibility tier, and demonstrates it on the OTA-delivered ODD speed extension of a deployed L3 ALKS (UN-R157). |
