Description
Technical Field
The invention relates to the technical field of new energy automobiles, in particular to a construction method, a topological structure and a storage medium of a centralized automobile electronic and electric framework.
Background
With continuous innovation of automatic driving technology, promotion of high-quality vehicle-mounted entertainment audio and video, and development of a series of technologies such as Over The Air (OTA), V2X, big data, cloud computing and the like, the current automobiles become more and more scientific, intelligent and interconnected. The promotion of the technologies brings higher and higher standards and requirements on the aspects of bandwidth, expansibility, open interconnection, cost and the like of the vehicle-mounted network in the automobile industry, and the existing vehicle-mounted network architecture taking the CAN bus as the leading factor cannot meet the development and innovation of the future automobile technology. The technical advantages of the vehicle-mounted Ethernet well meet the requirements of the automobile industry on high-speed data transmission and network open interconnection of the vehicle-mounted network, have higher expansion potential and become the mainstream vehicle-mounted network technology of the next generation.
The automobile realizes high-level automatic driving/auxiliary driving functions, and tends to improve user experience, for example, quick function updating and upgrading are met, and personalized, humanized and differentiated functions and services and the like can be provided. However, these trends inevitably bring new requirements, such as vehicle electrical and electronic architecture, electronic control unit computing power, network communication bandwidth, and network information security. The rapid development of the in-vehicle ethernet technology makes it much easier to introduce a Service-Oriented design into the automotive industry, and a Service-Oriented Architecture (Service-Oriented Architecture) provides a good solution for future vehicle software services. Different from a signal-oriented architecture in the traditional automobile electronic and electrical architecture, a service-oriented software architecture (SOA) is combined with a centralized electronic and electrical architecture taking a high-performance computing platform, namely a domain controller, as a core in the future through a standardized service interface, a loosely-coupled service mechanism and combinable and extensible service characteristics, and becomes a technical foundation of software-driven innovation in the future automobile field.
The existing electronic electrical Architecture is difficult to meet the requirements of the current automobile development, the future automobile Domain-Oriented electronic electrical Architecture (Domain-Oriented) and the future area-Oriented electronic electrical Architecture (Zone-Oriented) are combined, and the SOA (Service-Oriented Architecture) Architecture is applied to realize the rapid iteration and flexible recombination of the business process (function), so that a good platform solution is provided for the software personalization and innovation requirements under the intelligent networking trend.
SOME/IP (Scalable Service-organized Middleware IP) is positioned at an application layer of an OSI 7-layer model, is core content in a vehicle-mounted Ethernet technology, can be used for controlling message and application data transmission, and is an important support of an SOA framework.
SOME/IP (Scalable service-organized MiddlewarE over IP) is a concept introduced by vehicular Ethernet communication, and is located above layer 4 of the OSI 7-layer model. In the vehicle-mounted network mainly based on the CAN bus, the communication process is signal-oriented (except for diagnosis communication), which is a communication process realized according to the requirement of a sender, and when the sender finds that the value of a signal changes or a sending period is up, information is sent regardless of whether a receiver has the requirement or not. The SOME/IP is different and is sent when the receiver has a need, which has the advantage that no excessive unnecessary data will be present on the bus, thus reducing the load.
The prior art provides an enhanced central gateway for vehicle networking comprising a processor and memory connected to a plurality of vehicle buses. The central gateway of the vehicle receives raw data from the electronic control unit via one of the vehicle buses, expands the raw data with availability information, classification information, and environmental information, publishes the raw data to a publication/subscription topic hosted by the memory, and subscribes at least another ECU of the vehicle to the publication/subscription topic. The database of the central gateway is accessed for expanding the raw data with the availability information, the classification information and the environment information according to the determined type of raw data received by the central gateway of the vehicle from the electronic control unit via the vehicle bus. The extended data is provided to a publish/subscribe topic hosted by the gateway for access by a service external to the vehicle over a communications network. The method introduces a specific communication function of a central gateway, introduces a service-oriented communication concept of publish/subscribe, but aims at the traditional separated automobile electronic and electrical architecture, does not describe a communication topological diagram of a whole automobile, does not reduce the number of wire harnesses, sensors and electronic control units on the automobile, and does not support the SOME/IP communication protocol specially applied to automobile service-oriented.
