METHOD AND APPARATUS OF LOCATING SLOT IN STATIC SEGMENT FOR RELIABILITY IN FLEXRAY COMMUNICATION

摘要

PURPOSE: A method and an apparatus for arranging a slot in a static segment are provided to maximize real time property and extensibility by minimizing delay of transmission time. CONSTITUTION: Transmission preparing time for a message with a specific length is calculated(S410). The number of kinds of message cycle is calculated(S420). Transmission preparation times are integrated and the total transmission preparing time for transmitting one cycle is calculated(S430). The number of dummy slots is calculated(S440). The dummy slot is arranged in a front of the FlexRay cycle(S450). A message is allocated behind the FlexRay cycle considering a priority(S460).
