Technical Field
The utility model relates to the field of automobiles, in particular to whole automobile network management.
Background
In recent years, the complexity of an electronic system is continuously increased, the code amount of software is rapidly increased, a five-door hardware platform is poor in reusability, and after hardware is replaced, software is often pushed to be rewritten, at the moment, AUTOSAR can provide a standardized software interface and exchange format for people, the basic software standard of an automobile system is a standard stack across OEMs, the AUTOSAR methodology and software architecture are accepted by more and more OEMs and suppliers, and therefore a scheme that master-slave mode and AUTOSAR network management exist in the same network architecture needs to be designed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of realizing a network system structure which realizes master-slave and AUTOSAR network management and is in the same network architecture.
In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a have car network management system of master-slave mode and AUTOSAR network concurrently, the vehicle is equipped with CAN bus communication, CAN communication bus passes through CAN network segment and connects on-vehicle system, its characterized in that: the CAN network section comprises an AUTOSAR network and a master-slave network, the CAN communication bus is connected with the power CAN and the chassis CAN through the AUTOSAR network, and the CAN communication bus is connected with the auxiliary CAN, the vehicle body CAN and the information CAN through the master-slave network.
The vehicle is an electric vehicle, and the CAN communication bus is connected with the new energy CAN through a master-slave network.
The AUTOSAR network is provided with two paths and is connected with the CAN communication bus through the gateway to realize the data interaction with the CAN communication bus.
The gateway of the master-slave network accessing the CAN communication bus is a master node, and other nodes are slave nodes.
The controllers of the system which is accessed into the CAN communication bus through the AUTOSAR network are in an equal relation.
The communication speed of the master-slave network is 500kb/s, and the communication speed of the AUTOSAR network is 2M/s.
The utility model stores the master-slave mode and AUTOSAR network management in the same network architecture, and the long-period controller can directly follow the network management mode of the existing project, thereby meeting the requirement of using the AUTOSAR network management mode in the project period and saving the cost.
Drawings
The following is a brief description of the contents of each figure in the description of the present invention:
fig. 1 is a schematic diagram of a system network topology.
Detailed Description
The following description of the embodiments with reference to the drawings is provided to describe the embodiments of the present invention, and the embodiments of the present invention, such as the shapes and configurations of the components, the mutual positions and connection relationships of the components, the functions and working principles of the components, the manufacturing processes and the operation and use methods, etc., will be further described in detail to help those skilled in the art to more completely, accurately and deeply understand the inventive concept and technical solutions of the present invention.
The AUTOSAR network has a standardized application interface and a unified methodology, has obvious advantages and becomes a mainstream architecture model, combines the AUTOSAR network with a master-slave network to form a whole vehicle CAN network architecture, reduces the number of newly developed parts, reduces the cost of the whole vehicle, CAN realize the platform of the gateway, and does not need to develop the gateway again because of the upgrade of the architecture.
As shown in fig. 1, a 4-way high-speed CAN network segment and a 2-way high-speed CAN fd network segment are respectively connected to a CAN communication bus, and the accessible systems depend on the systems equipped on the vehicle, for example, a conventional electric vehicle has 32 systems participating in bus communication, wherein 24 high-speed CAN network segments and 8 CAN fd network segments. The 4 paths of CAN high-speed channels are respectively a new energy CAN, an auxiliary CAN, a vehicle body CAN and an information CAN, and the communication speed is 500 kb/s; the 2 CANFD high-speed channels are respectively a power CAN and a chassis CAN, and the communication speed is 2M/s.
The communication of each network segment realizes rate conversion and data interaction through a gateway, the gateway simultaneously carries out unified management on the whole vehicle network while realizing the data interaction, when the whole vehicle network of a host factory generally adopts one of AUTOSAR network management or OSEK network management, the master-slave network management and the AUTOSAR network management are simultaneously stored in the same network architecture, wherein the power CAN and the chassis CAN adopt the AUTOSAR network management, other four-way CAN adopts the master-slave network management, and the gateway realizes the overall management of the two kinds of network management. Master-slave network management: the gateway is a main node, other nodes except the main node are slave nodes, and the awakening dormancy of the whole network is controlled by the main node. AUTOSAR network management: the controllers on the whole vehicle are not divided into a master controller and a slave controller, all the controllers are equal, and all the controllers realize sleep awakening according to the network management strategy.
The utility model has been described above with reference to the accompanying drawings, it is obvious that the utility model is not limited to the specific implementation in the above-described manner, and it is within the scope of the utility model to apply the inventive concept and solution to other applications without substantial modification.
