Design And Implementation Of Vehicle Information System For Hybrid Electric Vehicle

Enter since twenty-first Century,energy security and climate change have become the focus of international society,in order to realize the healthy and sustainable development of the traffic field,the world's major automobile producing countries to promote the development of energy-efficient car accelerated further,in recent years,the global electric cars and hybrid cars will enter a rapid development stage of industrialization.When we need to understand the real-time traffic information,charging stations of the service point,auto fault information and so on.This requires the support of Internet of things,and vehicle information terminal designed in this paper is the core to realize hybrid cars and networking connection.Secondly,analysis and treatment of HEV terminal information data,and also provide more convenient service for the user;as a correct prediction and corresponding measures for dispatching center city traffic.Vehicle information terminal current mostly pauses in the design and implementation,we design and implement a hybrid car vehicle information system to carry out the Internet query,analysis and diagnosis.Firstly,according to the requirements of the overall design of vehicle information system for hybrid electric vehicle,the vehicle information system for hybrid electric vehicle is mainly divided into two parts of vehicle terminal and information management center,and separately carries on the design and analysis of each part of the.Among them,the vehicle terminal part respectively to exploit and research from the design of hardware and software in detail.The vehicle terminal,CAN bus based on the technology of the network interface with CAN/TTCAN,installed in the demonstration vehicle operation,data interaction through the CAN interface to access the vehicle control bus network and vehicle controller,and the related data analysis and encryption,transmitted by GPRS wireless network.Interactive data mainly includes motor,battery and vehicle operation data and vehicle controller,motor controller,a battery management system feedback information.Secondly,this text mining to hybrid vehicles information management center and data to do the research and analysis.Information center platform includes two parts:client and server.The system adopts the three layer system architecture of the B/S,in essence,is a kind of improved C/S architecture.The user interface work to achieve through the IE browser,very few parts of business logic in the front(Browser)to achieve,but the main business logic in the server(Server)to realize.Finally,test and verification system.This system uses the wireless network of Telecom,Unicom,mobile three operators to compare test.Then,using the wireless network operators the best transmission of analytical testing system,between the vehicle terminal and the server data packet,so as to realize the remote monitoring function of hybrid electric vehicle.
