AN IN-DEPTH ANALYSIS OF CAN BIT-TIMING AND DELAY SOURCES
Mahmut Tenruh · DergiPark (Istanbul University) · 2002
Controller Area Network (CAN) is an asynchronous real-time serial communication bus with high performance and a robust error recovery mechanism. CAN was first developed for combining all electrical controls on a serial data bus in automotive applications. Because of its low cost and high speed, CAN technology has also become popular for distributed realtime control systems in industrial environments. On the other hand, it also has some restrictions, such as bus length limitations, because of its medium access control (MAC) method and propagation delays in communication. In order to explain these rarely found specific issues, this paper aims to provide a detailed analysis of the CAN bit-timing and the delay sources in a CAN system for researchers
