PAN Hui, WANG Yi · DOAJ (DOAJ: Directory of Open Access Journals) · 2014
FlexRay bus has become the standard of similar products and it will lead the direction of the development of automotive electronics control system for a long time. This paper proposes a design of automobile engine control system based on FlexRay bus.In order to improve the network rate,reliability and flexibility,it adopts high-performance MC9S12XF512 microcontroller of Freescale and FlexRay bus driver TJA1080 of NXP company,and it gives the overall circuit design and software design process of automobile engine control system. The design has the characteristics of simple hardware circuit,high reliability and good real-time performance. It offers a certain reference value for the development of FlexRay bus node of engine control system.
