AUTOSAR 通信
配置通信端口和接口
AUTOSAR 软件组件的通信接口由明确定义的端口组成。AUTOSAR 组件通过其端口与其他 AUTOSAR 软件组件或基础软件 (BSW) 服务进行通信。端口向其通信合作方提供信息，或向其通信合作方请求信息。基于组件功能需求，组件拥有的每个端口都映射到一个通信接口。通信接口包括：
发送方-接收方 (S-R) 接口，用于消息传递
客户端-服务器 (C-S) 接口，用于函数调用
模式-切换 (M-S) 接口，用于管理基于模式的执行
非易失性 (NV) 数据接口，用于基于端口的 NV 数据访问
参数接口，用于基于端口的参数数据访问
触发器接口，用于管理基于触发器的执行
要为组件端口配置 AUTOSAR 通信，您需要创建一个 AUTOSAR 接口，将端口映射到该接口，并将 Simulink® 元素（如根输入端口或输出端口）映射到接口类型要求的 AUTOSAR 端口。使用 AUTOSAR 字典和代码映射编辑器或等效的 AUTOSAR 属性和映射函数。
