Time-Triggered Cooperative Scheduling Distributed Embedded System and its Application in Vehicle ACCS

Abstract

基于CAN总线的分布式嵌入式控制系统的应用日益普遍,系统控制和保护功能愈来愈复杂。在研制这些安全性要求很高的系统过程中,必须对其数字控制器进行充分的测试和参数整定。在完全消除控制器硬软件错误之前,就直接使用实际系统进行测试是不合适的。解决上述问题的途径之一是采用实时仿真系统,即将实际“执行器——整车——传感器”代之以实时模型,与实际控制器构成闭环控制系统。由于该实时仿真测试系统回路中具有实际微控制器和接口硬件,因而被称为硬件回路仿真(Hardware-In-the-LoopSimulation),简称HIL。本文跟踪国内外的最新研究成果,建立了一种软硬件相结合的基于ARM7LPC2119的HI...Distribute Embedded Systems (DES) which are based on CAN-bus are implemented everywhere, the function of control and protection of the system is become more and more complicated. During the manufacturing these highly safety required system, it is need to implement full test and parameter confirming of the digital controller. It is not appropriate to test on the real system,before debug the all mal...学位:工学硕士院系专业:软件学院_计算机应用技术学号:20034001
