COMMUNICATION MESSAGE CONVERTING APPARATUS AND COMMUNICATION MESSAGE CONVERTING METHOD

A communication message converting apparatus and a communication message converting method are provided to convert a message in a high speed without delay by separately installing a scheduling circuit and a routing circuit. A communication message converting apparatus includes a CAN(Controller Area Network) data process circuit, a routing circuit(29), a FlexRay scheduling circuit(23), a CAN scheduling circuit(24), and a status detection circuit(28). The CAN data process circuit receives and stores CAN frame data. The routing circuit(29) detects transmitters from FlexRay receiving data and CAN receiving data and stores data in FlexRay transmission buffer(26) or CAN transmission buffer(27). The FlexRay scheduling circuit(23) obtains data from the FlexRay transmission buffer(26) according to a time trigger schedule of a FlexRay and sets the data on a FlexRay controller(10). The CAN scheduling circuit(24) obtains data from the CAN transmission buffer(27) according to an event trigger schedule of a CAN and sets the data on a CAN controller(12-1). The status detection circuit(28) detects FlexRay and CAN bus status and performs a fail safe process.
