Automatic FIBEX generation from CANdb for FlexRay network

Abstract

As vehicles become more intelligent for safety and convenience of drivers, IVN(In-Vehicle Network) requires high speed of transmission and hardware redundancy for safety. FlexRay was developed to replace Controller Area Network (CAN) protocol in chassis networking systems to provide mote transmission capacity and shorter real-time transmission delay. However, FlexRay has many related parameters such as base cycle and slot lengths to be determined in the design stage. To assist vehicle network designers in configurationg a FlexRay network, this paper presents automatic field bus exchange format (FIBEX) generation method for migration from CAN message format such as CANdb to FlexRay FIBEX format.
