隨著汽車工業的快速發展，汽車控制已從傳統類比機械式控制方式，演進到大量的電子化控制，汽車仰賴電子系統來提供安全、舒適和娛樂等功能，因此車用電子控制愈來愈多樣化；更因為汽車為人員載具的特性，其安全性格外受到重視，因此精確的電子控制與反應便非常重要；且車用嵌入式系統需要在嚴苛的環境中執行，系統穩定度為首要考量。本篇論文著重於車用嵌入式軟體系統之研究，藉由車用即時作業系統OSEK/VDX之標準規格，來探討車用嵌入式軟體之機制與架構，提供車用電子控制器軟體開發的設計與應用參考。

With the rapid development of automotive industry, automobile control evolves from traditional analog mechanical methods to vast electronic ones. Automobiles rely on electronic systems to provide safety, comfort, and entertainment functions. Therefore, more and more diversified automotive electronic controls are needed. Automobiles, as manned vehicles, their security got more attentions. Precise electronic control and rapid response are very important. The stability is the first priority for automotive embedded systems since they need to work in harsh environments. In this paper, we have more emphases on the embedded software system of vehicles. We investigate the standard specifics of the OSEK/VDX of the car real time operation system. We also have some investigations on its software architectures and mechanisms for developing the control software for ECU in the future.
