电动汽车中的整车控制器软件系统设计

Design on Software System of Vehicle Controller for Pure Electric Vehicle

阐述采用主流开发流程V模型,针对纯电动汽车的整车控制器软件系统进行开发设计,系统程代码按MISRA-C规则进行,整车通信基于CAN2.0协议,软件架构参考汽车开放系统架构(AUTOSAR)。在整个软件系统中,驱动层程序的应用接口与硬件相隔离,调度层通过调用驱动程序完成上电自检、故障诊断和保护以及安全运行等系列工作,最终助力核心层控制策略的实现。

This paper describes the mainstream development process V model which is adopted to develop and design the software system of the whole vehicle controller for the pure electric vehicle.The system code is carried out according to the MISRA-C rule,and the whole vehicle communication is based on the CAN2.0 protocol;The software architecture refers to the Automotive Open System Architecture(AUTOSAR).In the whole software system,the application interface of the driver layer program is isolated from the hardware.The scheduling layer completes a series of tasks such as power-on self-test,fault diagnosis and protection,and safe operation by calling the driver program,and finally helps the realization of the core layer control strategy.
