Time Triggered Controller Area Networking
Communication protocols may be divided into two classes: event triggered and time triggered. Both these methods vary as far as their operating principles are concerned [Leen and Heffernan 2001].
Time-triggered controller area network (TTCAN) is a communication protocol based on CAN, though the difference is that it uses a time-triggered mechanism rather than the event-triggered mechanism used in CAN. The specifications of TTCAN are defined in ISO standard 11898-4. It uses all the error detection mechanisms as well as the soundness of CAN [Shrinath and Emadi 2004].
