電動巴士與商用車數位孿生開發平台 2022/07/12

簡介 Introductions

導入國際車廠正向開發方法與 V 型開發流程，促進國產電動巴士與商用車自主開發。應用數位孿生開發平台執行設計審查，實現車輛開發初期評估整車性能與可行性，並減少後期執行問題診斷所需的實車驗證成本與時間。

Importing forward development method as long as V-shaped developing process adopted by International vehicle manufacturers, which accelerate independent development of domestic electric buses and commercial vehicles. Design review is implemented by applying digital-twin development platform, which realizes vehicle performance and feasibility evaluation at early stage of vehicle development cycle. Further, reducing cost and time of real vehicle verification for trouble shooting at post stage of vehicle development cycle.
