摘要

目前車子的功能和可靠度正快速增加，然而價格卻下降中。因此越來越多電子控制單元（ECU）應用於車子中。今天超過50個ECU被使用於車子中，且人們設計CAN Bus以降低開發成本。透過CAN Bus的使用，使得ECU與ECU之間可以相互通訊，資料訊息將也會被順利送往每一個控制設備。因此，CAN Bus在車用網路上扮演了一個很重要的角色。在本論文中，為了達成安全性和可靠性於車用即時嵌入式系統之中，我們將研究ERIKA Enterprise車用軟體架構。ERIKA Enterprise屬於一個開放式軟體資源，透過該軟體的運用，車用即時作業系統（OSEK）可以很容易移植進入車用ECU硬體之中。最後，我們做一個簡單的實驗，來證實資料是如何透過CAN Bus送出，以確保即時性。

The automobile functions and reliability are increasing rapidly, but the price is decreasing. Therefore, there are more and more ECUs (Electronic Control Unit) will be conducted into the car. Today, there are about more than 50 ECUs used in the high-level automobile, and people designed CAN Bus to decrease the development cost. By applying the CAN Bus, we can make the ECUs communicate with each other, moreover, the data message will also be sent to each control device. Therefore, it is an important paradigm for CAN Bus in the CAR-based real time control system. In this paper, to achieve much safety and reliability for the real-time control, we would research automotive software framework for ERIKA Enterprise. The ERIKA Enterprise is an open-source software implementation and through the conducting of ERIKA software, the real time operating system for OSEK can be ported (embedded) into the target ECU hardware in a very easy way. Finally, we propose a demonstrative application for enhanced CAN bus network connection to show how real-time transmission of data frames through CAN bus network connection is guaranteed by ERIKA Enterprise.
