| Abstract: | The real time ability of the Controller Area Network is researched and the composition of delay time of message transmission based on CAN systems is analysed.The frame and MAC (Medium Access Control) delay time are mainly discussed, and software delay time and CAN Controller delay time are mentioned as well. Besides, PC communication experiment based on CAN is designed to imitate message transmission between two net nodes in order to validate some work conditions of CAN and explore the methods improving the realtime ability and reliability of CAN. |
