基于AUTOSAR的电动汽车中央控制单元CAN通信软件开发

Development of CAN Communication Software for Electric Vehicle Central Control Unit Based on AUTOSAR

随着人们对于汽车安全性和舒适性要求的日益提高,汽车电子技术不断发展,日益复杂的汽车功能需求使得汽车ECU软件代码量急剧增加。软件与硬件之间的高度耦合使得开发工作大量重复且复用性低,极大增加了企业研发和维护成本。以AUTOSAR架构为基础,进行以电动汽车中央控制单元为硬件平台的CAN通信模块软件开发,提升软件的复用性和开发效率,降低软件更新和硬件升级的研发成本。

With increasing of requirements for automotive safety and comfort and developing of automotive electronic technology,the more and more complex automotive functional requirements have led to a sharp increase in automotive ECU software code.The high coupling between software and hardware produces a lot of repetition work with low reusability,which greatly increases the cost of R&D and maintenance.Based on the AUTOSAR architecture,this paper develops the CAN communication module software with the electric vehicle central control unit as the hardware platform to improve the reusability and development efficiency of the software,and reduce the R&D cost of software updates and hardware upgrades.
