考量安規驗證的汽車電子產品開發時程規劃-以語音助理模組及OTA模組為例

Abstract

本研究聚焦於語音助理模組與 OTA 模組在車載電子產品開發流程中導入驗證節點之成效與挑戰。面對 ISO 26262、ISO 21434、ISO 24089 等標準對模組化驗證的高強度要求，企業在開發排程與資源配置上普遍面臨時程延誤、驗證重工與稽核補件等風險。為此，本研究結合 ASPICE 架構與 V-Model 理論，建構模組節點化驗證模型，並透過模擬甘特圖、交錯資源矩陣與 KPI 成效比較分析等方法，進行模組層級之驗證效益評估。 研究顯示，若於開發初期明確預排模組驗證節點，並搭配節點資源分流與標準配對機制，可顯著提升交付準時率（+25%）、驗證覆蓋率（+20%）與首次稽核通過率（+30%），同時降低 50% 測試重工與時程衝突風險。語音模組需強化語意測試與 SOTIF 模擬，OTA 模組則須佈署資安測試與第三方稽核節點。實證模擬進一步指出，導入驗證節點策略後，模組平均交付週期可提前 3～5 週完成，有效因應 OEM 驗收與法規合規需求。 本研究所建構之模組節點驗證模型與 KPI 對照模板，可作為未來企業導入節點化驗證策略、建立模組驗證規劃基準與稽核對應資料之參考依據。

This research focuses on analyzing the impact and strategic benefits of introducing verification nodes in the development process of automotive electronic products, particularly for voice assistant and Over-the-Air (OTA) modules. Amid increasingly stringent requirements from ISO 26262, ISO 21434, and ISO 24089 standards, product teams often face challenges such as schedule delays, rework, and audit failures. To address these challenges, this study applies ASPICE V-Model-based modeling to construct a modular verification node framework. Using Gantt chart simulation, overlapping task matrices, and KPI benchmark comparisons, the study evaluates performance gains derived from structured node implementation. The results demonstrate that early-stage verification node planning, coupled with resource segmentation and standard-specific mapping, can enhance delivery punctuality (+25%), verification coverage (+20%), and first-pass audit rates (+30%), while reducing rework rates and schedule conflicts by over 50%. The voice assistant module benefits significantly from semantic intent and SOTIF validation, whereas the OTA module requires rigorous cybersecurity testing and third-party audit preparation. Simulations show that verification-driven strategies can shorten average module delivery timelines by 3 to 5 weeks, improving readiness for OEM approval and regulatory compliance. The modular verification planning framework and KPI evaluation models developed herein can serve as practical references for enterprises implementing node-based development strategies and establishing compliance-ready verification documentation.
