The invention relates to an automobile external light software architecture and a construction method. The software architecture comprises an application software layer, an operation environment layer, a basic software layer and a hardware layer. The application software layer is located at the topmost layer, the operation environment layer is located between the application software layer and the basic software layer, and the basic software layer carries out unified packaging on the microcontroller and the hardware layer; and the hardware layer comprises a microcontroller and a peripheral circuit. According to the invention, functional modules of all parts of external light, occupation of hardware and software resources and an interaction relation of the functional modules and the hardware and software resources are combined with an AUTOSAR hierarchical architecture standard system, and a hierarchical principle of application of the AUTOSAR in an automobile external light control software architecture is provided; functions of input acquisition, function control, fault diagnosis, output control and the like of external light control are executed hierarchically according to a standard architecture, and the portability of upper-layer application software, the high decoupling of bottom-layer hardware and software and the high stability of the overall architecture are improved.
本发明涉及一种汽车外部灯光软件架构及构建方法,软件架构包括应用软件层、运行环境层、基础软件层和硬件层;应用软件层位于最顶层,运行环境层位于应用软件层和基础软件层之间,基础软件层对微控制器及硬件层进行统一封装;硬件层为微控制器及外围电路。本发明将外部灯光的各部分功能模块、硬软件资源的占用及其交互关系与AUTOSAR分层架构标准体系结合,提出AUTOSAR在汽车外部灯光控制软件架构应用的分层原则,将外部灯光控制的输入采集、功能控制、故障诊断和输出控制等功能按照标准架构分层级执行,提升上层应用软件的可移植性、底层硬件与软件的高度解耦性、整体架构的高稳定性。
