基于XC2000的智能进入及启动系统基站软件设计

基于XC2000系列微控制器进行了智能进入及启动(PEPS)系统基站的软件设计,参考汽车开放系统架构(AUTOSAR),将软件架构分为应用层、接口层和基础层,通过接口层将应用层与硬件平台分离开来,针对基站复杂的逻辑控制问题,应用层软件采用模块化设计方案,利用Stateflow分别搭建各模块模型。利用硬件在环测试系统对基站分别进行了功能测试和故障注入测试,结果表明,该基站可良好实现设计功能,性能可靠。

Base Station Software Design of the Passive Entry & Passive Start System Based on XC2000

Based on the XC2000 series of microcontrollers,the software design of the base station of the Passive Entry&Passive Start(PEPS)system is carried out.Referring to the Automotive Open System Architecture(AUTOSAR),the software architecture is divided into an application layer,an interface layer,and a base layer,and the application layer is separated from the hardware platform through the interface layer.For the complex logic control problem of the base station,the application layer software adoptes a modular design scheme,and all the module models are built by Stateflow separately.The hardware-in-the-loop test system is used to perform functional test and fault injection test on the base station.The test results show that the base station can achieve good design functions and reliable performance.
