Problems solved by technology

Although this platform architecture method is conducive to team collaborative development, this idea of ​​​​using functional similarity as a module division method usually only cares about the interface between modules and code functionality. Each module is still a relatively independent "small system", only emphasizing The internal software development standards (programming language and operating platform, etc.) of each module "small system" are unified, regardless of the development standards of the entire smart car data system

Abstract

The invention relates to an intelligent vehicle data platform architecture based on distributed nodes and a virtual bus model. The intelligent vehicle data platform architecture is characterized in that the intelligent vehicle data platform architecture comprises a virtual bus, a plurality of nodes, a main controller and a monitor; the virtual bus is used as a communication carrier for completing data transmission based on a TCP / UDP communication protocol or local process communication, and the plurality of nodes are mounted on the virtual bus; and the main controller uses the virtual bus to configure and call corresponding nodes according to task requirements, and the monitor uses the virtual bus to monitor and record states of related nodes in real time in the system operation process. The intelligent vehicle data platform architecture can be widely applied to the exploitation of an intelligent vehicle data system.

Description

technical field [0001] The invention belongs to the technical field of intelligent vehicles, in particular to an intelligent vehicle data platform architecture based on a distributed node and a virtual bus model. Background technique [0002] Intelligent driving technology has great application potential in traffic safety, environmental protection, and traffic pressure relief. It has become the research focus of developed countries, automobile manufacturers, and technology companies. Intelligent driving research involves many disciplines such as mechatronics, pattern recognition, artificial intelligence, control science, and software engineering. Among them, intelligent vehicle software algorithms are one of the important contents of the research.
