The software device program software structure of the self-driving car controller system includes software device program software and application software program software.
The software device program software covers the Linux operating system, ROS middleware, and a general framework. The application software is divided into three parts: first, the basic software services that mostly consist of data acquisition interface APIs, vehicle-by-wire interface APIs, map interface APIs, and integrated navigation provider programs; second, the specialized customized software services that mainly comprise self-driving application software (perception, decision-making, control, and their sub-modules), communication services, and human-computer interaction interfaces.
Concerning the Linux operating system, the Ubuntu distribution is selected as the system for the controller platform. The Linux system has a number of advantages over other operating systems. One of them is being open-source, which makes it very attractive for further research and learning. Besides that, the Linux system is quite a stable one, it supports long-term operations without any breaks, and is very economical when it comes to memory usage.
By opening up distributed communication services to link initially loosely coupled components, the ROS middleware enables code reusability, distributed communication services, a large number of plug-ins and simulation tools, offers a rich library, and ensures compatibility with several programming languages, including C++ and Python. ROS provides functionalities that an operating system needs to have, among others, hardware abstraction, basic device control, execution of common functions, inter-system message passing, and package management. ROS is shifting to a distributed framework, and via peer-to-peer architecture, nodes are allowed to function independently, thus giving modular change and customization as well as increasing the system's fault tolerance level. Modules use independent and unified interface definition languages for message communication between different modules.
The generic framework is equipped with generally used software application frameworks, like Cafe, TensorRT, TensorFlow, CUDA, etc. By means of the general framework, the artificial intelligence algorithms' running environment may be very simply set up.
Application software consists of one basic software service and severalspecialized, customized software services. Basic software services, in particular, comprise data acquisition interface APIs that allow collecting data from standard LiDARs, millimeter-wave radars, and network cameras; vehicle-by-wire interface APIs with CAN communication and message encapsulation/parsing functions; map interface APIs which assist in calling high-precision maps to deliver high-precision map services to the system; and integrated navigation company programs providing the system with centimeter-degree positioning services.
Specialized customized software services are the intelligent vehicle system's custom modules that are provided as per the exact task requirements or for unique algorithm verification. While working on the device, developers may concentrate on the implementation of specialized algorithms based on their research paper and not be concerned about modules in the system. All sub-modules are aware that there are loosely coupled connections among modules via the ROS communication mechanism and that each module can independently develop and optimize.
