An implementation of the enhanced-CAN BUS network connection in CAR real-time embedded software system

Today's automobile is featuring a large number of Electronic Control Units (ECUs). This will increase the system complexity, which will consequently increase the difficulties of programming design and safety and the software cost. Therefore, it is important to provide a reliable, real-time, effective and eventually a low-cost software development tool in the automotive industrial market. ERIKA Enterprise provides an open source for multi-processor real-time operating system kernel, implementing a collection of application programming interfaces similar to those of OSEK/VDX standard for automotive embedded controllers. In this paper, we research the automotive software framework for ERIKA Enterprise, and through the conducting of ERIKA software, the real time operating system for OSEK can be ported (embedded) into target ECU hardware in easily. Finally, we propose a demonstrative application for enhanced CAN (ECAN) bus network connection to show how real-time transmission of data frames through ECAN bus network connection is guaranteed by ERIKA Enterprise.
