Real-time Body Control System Design Based On Single Chip

Being the centralized reflection of rapidly developing modern high technology,modern automobile technology is in fact the production of multidisciplinary technologies including mechanics,electronics,computer,control engineering,material engineering,bioengineering,and information technology.Along with the rapid development of electronic technology,computer technology and control technology as well as increasing requirement on automobile,modern automobile is becoming more electronic and intelligent.The objective of the paper is to carry out basic research and development on automobile body control system and realize basic control function based on demand in current Chinese market,resulting in a foundation for further study on automobile electronic products.Based on domestic and foreign technical references related to automobile electronics,an advanced system control mode is firstly designed and realized in this paper.With centralization and distributed integration thought,the whole system design fully supports the communication function of vehicle network CAN and LIN.Meanwhile,the vehicle supports real-time response operation.Secondly,in the aspect of software design,the task scheduling policy is optimized for the weakness ofμC/OS-Ⅱ operating system in task scheduling.In addition,through the test,it is found that the optimized algorithm effectively saves the time spent in task scheduling.In the end,the body control test system is realized effectively and conveniently.Half-real and half-virtue test environment is used to integrate the software and hardware resources effectively.μC/OS-Ⅱ is used as the body software control system,and the CodeWarrior is used as the test environment of the whole body control system.The bottom control module drive is programed,which supports the task scheduling,interrupt serving,bus communication,and acquisition of self-check information in various functional modules of body control system.
