Flexray Communication Controller for Intra-Vehicular Communication and Its Realization in FPGA
Keywords:
Flexray, Electronic Control units, Field Programmable Gate ArrayAbstract
Intra-vehicular communication describes an exchange of data within the ECUs (Electronic Control Units) of the vehicle which are involved in vehicular applications. The Flex Ray protocol is a unique time-triggered protocol that provides options for deterministic data that arrives in an expectable time frame. In case of CAN (Controller Area Network) it provides a dynamic event-driven data to handle a large variety of frames. The Flex Ray communication cycle is the fundamental element of the media-access scheme within Flex Ray. The main advantage of flex Ray communication protocol is its constant latency. It also have dual channel for redundancy or faster transfer. This paper describes a field-programmable gate array (FPGA)-based communication controller (CC). This features configurable extensions to provide functionality that is unavailable with standard implementations or off-the-shelf devices. VHDL simulation & FPGA synthesis results of communication controller of flexray controller are tested on Quartus II version 12.1 are presented.
