Summary: | 碩士 === 中原大學 === 電子工程研究所 === 101 === In this thesis, we study the data schedule of communication cycle in the FlexRay. Each node will have the different transmission requirement. Suitable schedule on the static segment of FlexRay system can upgrade the capability of transmission network. We will study and set the static segment parameters of FlexRay communication cycle that can improve the transmission capability on the steady schedule. Using the utilization of static segment and the transmission time, we show the improvement of the utilization and transmission time. We build the improvement methodology of the FlexRay static segment by using Matlab GUI which makes the setting schedule parameters more convenient. Moreover, we design and build the FlexRay communication controller by the hardware description language (HDL). We use the Modelsim to simulate the functions. And we combine the HDL of the desing communication controller and the NIOS II host into FPGA, to verify the signal data by the logic analyzer. And we add the bus driver chip of the physical layer (TJA1080) to FPGA, to measure the analog signal by the FlexRay oscilloscope. We show the intercommunication of two FlexRay nodes with our implementation of the communication controllers. Finally, we use TZM development board to deliver the FlexRay frames with our design FlexRay FPGA node. The filed try communication of development board will show our implemented FlexRay communication controller with normal and successful operations.
