Design And Implementation Of A Smart Terminal For New Energy Vehicles

In recent decades,the development of vehicle technology has been advancing by leaps and bounds,the quality of life has been improved,the safety and convenience of vehicles and the basic driving functions have been unable to meet the needs of all.The demands of the masses change in a more secure,comfortable,advanced and intelligent way.In the automotive technology innovation,70%is come from the automotive electronics.In-vehicle smart terminal is the most attractive and fastest growing part of the automotive electronics,from car radio and cassette tape player which dates back to more than 20 years ago,,car radio and automatic turntable CD player 10 years ago,to the current car stereo sound system,global positioning system,voice control combination and communication systems,etc.,intelligent vehicle terminal has become the main form of products with the intelligent automotive electronics process,it has become the center of intelligent in-vehicle HMI,and plays an irreplaceable role.At present,all countries in the world are vigorously developing new energy vehicles,China has promoted the development of new energy vehicles to the national strategic height.How to design a suitable automotive intelligent terminal for new energy vehicles is the development of the market demand.This thesis analyzes and expounds the design of the intelligent terminal of new energy vehicle according to the enterprise market demand.This thesis analyzes the historical origin,current situation and development trend of the vehicle intelligent terminal,and also explores the rise and development of the new energy automobile industry.Synthesizing the market demand and the actual project of the company,the specific implementation steps of the new energy vehicle on-board intelligent terminal in this project are expounded.It is based on the universal high performance multimedia processor,SOC chip and embedded ARM dual processor,the former implements multimedia entertainment,while the latter completes security controls,through customized platform power management strategy,the terminal can achieve quick start and low power design.The intelligent terminal expanded the wireless communication,GPS positioning,CAN bus and voice recognition control module in the realization of information entertainment function,due to the new energy vehicle technology is not yet complete,so the terminal design can effectively monitor the vehicle motor,Battery and other real-time data status,to achieve fault warning tips to protect the safety of vehicles and drivers,while the vehicle data can be collected and analyzed for the vehicle manufacturers to upgrade the vehicle to provide a scientific basis for upgrading,through the deep customization and tailoring of Android embedded operating system,a scalable intelligent vehicle terminal based on vehicle networking and mobile Internet technology is implemented.Because the vehicle itself complex environment is bad,coupled with the electric vehicle work in a strong high voltage state,so the system has undergone strict electromagnetic compatibility and environmental testing,and ultimately achieved high reliability and stability,to meet the product standards and requirements.Finally,the whole design is summarized,and the future development of vehicle intelligent terminal is prospected.
