Automobile external light control software architecture and construction method

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 pro
