| Along with energy crisis's aggravation and the environmental protection performance requirement's enhancement, hybrid electric vehicle and the related research get more and more attention by people. Hybrid electric vehicle takes new generation's advanced vehicles, and its internal structure is very complex, electronic equipment is various. In the vehicle, the communication network is the channel of each electronic installation exchange information, its research and the design are a very important part of whole vehicle's R&D, Vehicle-mounted monitoring system can provide a friendly man-machine interaction contact surface, thus enhances the vehicles safety in operation and the communication reliability, therefore this part of research have the practical significance.In this thesis, at first, hybrid electric vehicle's internal communication network was studied, and SAE J1939 communication protocol was researched, then we designed and built the communication network's structure of the vehicle. The major component was to design a kind of reliable typical communication node of the vehicle, prime task including communication node's hardware architecture design and correlation communication software's compilation. The experimental result proves each node to be possible to carry on the fast effective exchange of information in this network.Through the automobile secure aspect's research, this article proposed several measures to enhance the vehicles security and communication reliability, and gave the monitoring system's design proposal and the function request. Selected a SAMSUNG Corporation's section of ARM processor to take the main processing chip, designed hardware circuits according to system's function request, and monitoring system's hardware platform has completed.On this basis, this thesis has designed the embedded operating system (Windows CE) and system mirror was given then, the key part is modification of BSP and design of communication module's driver. At last, according to the requirements of the function, the upper application software was designed. |
