综述和目标行业现状

电子系统的复杂性不断增长软件代码量急速上升生命周期差别:整车的生命周期往往长于ECU的生命周期嵌入式系统不支持硬件抽象有限的软件模块化重用性差:当硬件(处理器型号)更换后，软件往往要推倒重写五花八门的硬件平台

综述和目标目标

适用于整个产品生命周期从软件中把硬件抽象出来，对于不同硬件平台具有更大的灵活性更多的配置而非实现标准化AUTOSAR的代码配置/建模工具通过对BSW的标准化提高了代码质量竞争力只体现于对OEM的特殊功能要求的实现在整个汽车生命周期中，软件可以不断更新或升级重用性可以覆盖整个网络节点，甚至跨不同OEM

AUTOSAR入门软件组件(SWC)的分类

Atomic component (最小的逻辑单元，无法再分) Application实现算法

Sensor/actuator为Application提供I/O量与ECU绑定 (不像Application那样能在各ECU上自由映射)

Composition ->数个SWC的逻辑集合Light Control Composition Component
