Road vehicles -- Controller area network (CAN) -- Part 4: Time-triggered communication
This standard was last reviewed and confirmed in 2013. Therefore this version remains current.
ISO 11898-4:2004 specifies time-triggered communication in the controller area network (CAN): a serial communication protocol that supports distributed real-time control and multiplexing for use within road vehicles. It is applicable to setting up a time-triggered interchange of digital information between electronic control units (ECU) of road vehicles equipped with CAN, and specifies the frame synchronisation entity that coordinates the operation of both logical link and media access controls in accordance with ISO 11898-1, to provide the time-triggered communication schedule.
