符合AUTOSAR规范的TC277T动力域控制器软件开发

Software Implementation of Power Domain Controller According to AUTOSAR Specification TC277T

基于AUTOSAR软件架构规范,以英飞凌TC277T三核处理器单片机为域控制器开发平台,设计了包含整车控制器(VCU)+动力电池控制单元(BCU)的多合一动力域控制器系统(PDCS)的软件架构。从资源分配、功能组件划分和多核任务均衡的角度出发,对多核任务设计、软件组件之间通过实时运行环境(RTE)连接进行详细设计,并对多核任务调度、负载分配和软件功能分配进行了分析验证,实现了多合一域控制器的有效集成。研究表明,该嵌入式软件架构可有效应用于多合一域控制器软件设计,也为日后相关设计提供了适当的参考。

Based on AUTOSAR software architecture specification,Infineon TC277T triple-core processor single-chip microcomputer is used as the domain controller development platform.The software architecture of multi-in-one power domain controller system(PDCS)including VCU+BCU is designed.In this paper,from the perspective of resource allocation,functional component division and multi-core task balancing,multi-core task design and software component connection through RTE real-time running environment are designed in detail,and multi-core task scheduling,load distribution and software function distribution are analyzed and verified,and the effective integration of multi-in-one domain controller is realized.The research shows that the embedded software architecture can be effectively applied to the software design of multi-in-one domain controller,and also provides a suitable reference for future scholars and engineers.
