A Reliable Message Transmitting of Can-bus Network Connection Applied in Real-time Car-based Motor Control System

چکیده
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, besides the research of CAR-based motor control for message transmitting via the CAN bus network connection, we also 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 a very easy way. 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. In the other words, the motor control for CAR can also be managed by ERIKA to keep the data transmitting in a more real time and reliability.

متن کاملA Fast Voltage Collapse Detection and Prevention Based on Wide Area Monitoring and Control
Voltage stability is one of the most important factors in maintaining reliable operation of power systems. When a disturbance occurs in the power system, it usually causes instabilities and sometimes leads to voltage collapse (VC). To avoid such problems, a novel approach called Vector Analysis (VA) is proposed that exploits a new instability detection index to provide wide area voltage stabili...

A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...
