Shared communication protocol for a bus system of type Controller Area Network (CAN)

摘要

A method (30) of communicating messages in a CAN network (10) is provided. The method (30) obtains data to be transmitted that relates to an event, prepares a unique event message identifier (EMI) for first data that relates to the event and prepares a common data message identifier (DMI) for the event. The common data message identifier (DMI) identifies second data related to the event. The method further prepares a first transmit message (m4) comprising the unique event message identifier (EMI) and the first data relating to the event, and prepares a second transmit message (m8) comprising the common data message identifier (DMT) and the second data relating to the event, and transmits the first and second messages (m4, m8) to a CAN bus (12), wherein the first and second transmit messages (m4, m8) may be received by one or more receiving devices (14).
