Abstract:
FlexRay is an automotive communication protocol, which is developed by core members of the FlexRay consortium (BMW, Bosch, DaimlerChrysler, Freescale, GM, NXP Semiconductors and Volkswagen). Nowadays, it is set to become widely used in the automotive industry where it will replace traditional networking schemes such as Controller Area Network (CAN). However, in the FlexRay, it just uses the Cyclic Redundancy Check (CRC) code to detect the errors. In this paper, we design of a Hybrid Automatic Repeat Request (HARQ) scheme which combines the CRC code with Reed-Solomon (RS) code. Smart Hybrid Powerpack (SHPP) is an electro-hydraulic system, which is combined with advanced technology like fault tolerant, intelligent control, smart phone remote control and monitoring. This paper will apply the FlexRay into the SHPP system using the HARQ scheme. Simulation result shows good performance by using HARQ scheme comparing with CRC code only.
