Description

Construction method, topology and storage medium of centralized automotive electronic and electrical architecture

technical field

The invention relates to the technical field of new energy vehicles, in particular to a method for building a centralized vehicle electronic and electrical architecture, a topology structure and a storage medium.

Background technique

With the continuous innovation of autonomous driving technology, the advancement of high-quality in-vehicle entertainment, and the development of a series of technologies such as over-the-air (OTA), V2X, big data, and cloud computing, today's cars are becoming more and more technological. , intelligent and interconnected. The advancement of these technologies has spawned higher and higher standards and requirements for in-vehicle networks in the automotive industry in terms of bandwidth, scalability, open interconnection, cost, etc. The current in-vehicle network architecture dominated by CAN bus cannot meet the development of future automotive technology. and innovation. The technical advantages of in-vehicle Ethernet can well meet the needs of the automotive industry for high-speed data transmission and open network interconnection of in-vehicle networks, and have higher expansion potential, becoming the next-generation mainstream in-vehicle network technology.

While realizing high-level autonomous driving/assisted driving functions, automobiles also tend to improve user experience, such as satisfying rapid function updates and upgrades, and providing personalized, user-friendly, and differentiated functions and services. However, these development trends will inevitably bring about many new requirements, such as vehicle electronic and electrical architecture, electronic control unit computing power, network communication bandwidth, and network information security. The rapid development of in-vehicle Ethernet technology makes it much easier to introduce service-oriented design into the automotive industry. Service-Oriented Architecture provides a good solution for future vehicle software services. Different from the signal-oriented architecture in the traditional automotive electrical and electronic architecture, the service-oriented software architecture (SOA) combines with the future high-performance computing platform-domain through standardized service interfaces, loosely coupled service mechanisms and composable and scalable service characteristics. The controller, the centralized electronic and electrical architecture at the core, will become the technical basis for "software-driven innovation" in the future automotive field.

The existing electronic and electrical architecture is difficult to meet the needs of the current automobile development. Combined with the future automotive domain-oriented electronic and electrical architecture (Domain-Oriented) and zone-oriented electronic and electrical architecture (Zone-Oriented), the application of SOA (Service-Oriented Architecture, Service-oriented architecture) architecture can realize rapid iteration and flexible reorganization of business processes (functions), and provide a good platform solution for software personalization and innovation needs under the trend of intelligent network connection.

The implementation of SOA requires communication methods based on SOME/IP and TCP or UDP. SOME/IP (ScalableService-Oriented Middleware Over IP) is located in the application layer of the OSI 7-layer model. It is the core content of the vehicle Ethernet technology and can be used to control Message and application data transmission, this technology is an important support for SOA architecture.

SOME/IP (Scalable service-Oriented MiddlewarE over IP) is a concept introduced by in-vehicle Ethernet communication, which is located above layer 4 of the OSI 7-layer model. In the CAN bus-based vehicle network, the communication process is signal-oriented (except for diagnostic communication), which is a communication process implemented according to the sender's needs. When the sender finds that the value of the signal has changed, or sends When the period is up, the message is sent regardless of whether the recipient needs it or not. But SOME/IP is different. It is sent only when the receiver needs it. The advantage of this method is that there will not be too much unnecessary data on the bus, thereby reducing the load.

The prior art provides an enhanced central gateway for vehicle networking, including processors and memory connected to multiple vehicle buses. The vehicle's central gateway receives raw data from the electronic control unit via one of the vehicle buses, extends the raw data with availability information, classification information, and context information, and publishes the raw data to a memory-hosted pub/sub topic, at least Another ECU of the vehicle subscribes to the said pub/sub topic. Based on the determined type of raw data received by the central gateway of the vehicle from the electronic control unit via the vehicle bus, the database of the central gateway is accessed for expanding the raw data with availability information, classification information and environmental information. Provides extended data to a pub/sub topic hosted by the gateway for access by services external to the vehicle over the communication network. This method introduces a specific communication function of a central gateway, and introduces the concept of publish/subscribe service-oriented communication, but this method is aimed at the traditional separated automotive electronic and electrical architecture, and does not focus on the communication topology of the entire vehicle. It shows that the number of wiring harnesses, sensors and electronic control units in the car is not reduced, and this method does not support the SOME/IP communication protocol specially applied to the service-oriented of the car.
