[0044] Please refer to Figure 1 A structural schematic diagram of a vehicle communication matrix database system provided in the embodiments of the application includes:

[0045] The local end 10 and the server end 20;

[0046] The above local end 10 includes a change request function module 101, a communication matrix design module and a communication matrix search display module;

[0048] The server end 20 is used for storing data matrix information.

[0049] Exemplarily, the vehicle communication matrix database system provided in the application comprises a local end 10 and a server end 20, and the local end 10 comprises three functional modules of a change request functional module 101, a communication matrix design module and a communication matrix search and display module. The change request functional module 101 realizes online collaborative communication change management, optimizes offline process and realizes paperless process. The change request is filled according to a limited rule, so as to be automatically associated to the communication matrix parameters in the database for updating finally. The change request type can include adding a signal, adding a receiver, deleting a signal, deleting a receiver and modifying a signal. The communication matrix design module can realize development of the communication matrix, and the main functions include matrix database import and export, signal\Frame\ECU\Network attribute editing, matrix dotting and releasing and the like.

The server end 20 comprises a communication matrix special database, which mainly stores value table, signal table, frame table, ECU table, network table, attribute association and the like and performs related data processing.

[0050] In summary, the vehicle communication matrix database system provided in the application adopts a front-end and back-end separation network architecture, the local end 10 comprises three functional modules of a change request functional module 101, a communication matrix design module and a communication matrix search and display module, and the server end 20 comprises a communication matrix special database. Based on the high integration advantage of the current system architecture / management process, the problem of low correlation of three blocks of change demand management, communication design and matrix release in the communication matrix design is solved. Through the communication matrix management database system, the problems of high manual error rate, large offline repeated confirmation workload, poor correlation of communication matrices of different vehicle types, chaotic matrix generation tool chain and the like can be further solved, and the practical effect of one-stop matrix development, time saving and labor saving is achieved.

The technology can break through the barriers among communication demand management, matrix design and matrix release, has high functional integration degree and can be flexibly arranged according to the communication design and development process of the host factory, and has very good adaptability.

[0051] In some examples, the communication matrix design module 102 102 includes a data interaction unit 1021, an attribute editing unit 1022, and a dot release unit 1023.

[0052] The data interaction unit 1021 is used for import and / or export operations of the data matrix with the server 20.

[0053] The attribute editing unit 1022 is used for editing operations of signal attributes, ECU attributes, and network attributes associated with the data matrix.

[0054] The dot release unit 1023 is used for automatically generating communication matrix data according to preset time information.

[0055] For example, the data interaction unit 1021 is mainly used for excel or dbc, ldf file import and export operations for enterprise-developed or default file templates. The attribute editing unit 1022 can mark attributes for signal, Frame, ECU, and Network, respectively. These attributes can facilitate developers to better compare and contrast multiplexing or differences of signals. It can be understood that corresponding attributes, such as vehicle model code and configuration, need to be created in advance. The dot release unit 1023 mainly realizes on-demand point generation of the communication matrix, and automatically generates a change history according to the change during the period.

[0056] In some examples, the dot release unit 1023 is also used for configuring release attributes, release stages, release times, and release files.

[0057] For example, the matrix dot release function of the dot release unit 1023 can be configured through a configuration interface. The functions mainly include configuring release attributes (such as project code), release stages\versions, release time points (which can be accurate to seconds), release files (filtering demand files and selecting them), and the like. The dot release unit 1023 generates the latest release file according to the network time to the specified time point according to the communication matrix database, and sends the release file to the specified folder (cloud folder). The specified party is notified by email, and each demand party can obtain the communication matrix file in the specified location.

[0058] In some examples, the change request function module 101, the communication matrix design module, and the communication matrix search and display module can simultaneously realize related operations corresponding to the CAN matrix and the LIN matrix.

[0059] Exemplarily, the CAN matrix and the LIN matrix are both matrices for describing the communication relationship between devices in a vehicle communication system, which can be used for analyzing, optimizing and managing the communication system, and improving the efficiency and safety of the vehicle communication system. Generally, it is composed of node ID, data frame ID, data length, data type, data direction and other information. Through the CAN / LAN matrix, the communication relationship between nodes in the CAN / LAN bus can be clearly described, including the transmission direction of data, the type of data and other information, which is helpful for analyzing, optimizing and managing the CAN / LAN bus.

[0060] In a second aspect, as Figure 3 shown, a control method for the vehicle communication matrix database system of any one of the first aspect is provided, comprising:

[0061] S210, according to the demand side in the above change request function module to change request to the corresponding client of the associated party to send inquiry information to seek the confirmation of the associated party of the change request;

[0062] Exemplarily, the vehicle communication matrix database system can complete communication change management through the change request function, including adding signals, adding receivers, deleting signals, deleting receivers, modifying signals, etc. The demand side is the change request initiator. After the demand side proposes a change request in the change request function module, the local end sends inquiry information to the client of the rest of the associated parties to seek confirmation of the associated parties of the change request.

[0063] S220, in the case of all associated parties confirming, sending the above change request to the client corresponding to the developer to seek the developer's review;

[0064] Exemplarily, in the case of all associated parties confirming, the process flows to the communication matrix developer for review. It should be noted that when the change request is issued, the communication designer can synchronously obtain the request change information and understand the details of the change request in advance, which is beneficial for the communication designer to synchronously understand the situation and make evaluation.

[0065] S230, in the case of obtaining the above developer review feedback information, executing the change operation based on the above change request information.

[0066] Exemplarily, in the case of all associated parties confirming and the design personnel checking through, the change operation is executed according to the change request information after the change request.

[0067] In summary, the control method of the vehicle communication matrix database system proposed in the embodiments of the present application synchronously updates the non-communication matrix designers when the demand side proposes a change request, so that the communication designers can synchronously understand the situation and make an evaluation, thereby shortening the change cycle, and performing a change operation according to the change request when all the associated parties and developers agree.

[0068] In some examples, the method further includes:

[0069] obtaining data attribute information input by the searcher in the communication matrix search display module, wherein the data attribute information includes at least one of signal attribute, ECU attribute and network attribute associated with the data matrix;

[0070] calling the data matrix information stored in the server based on the data attribute information and displaying the corresponding target data matrix information.

[0071] For example, the communication data display module can perform horizontal comparison (such as attribute marking) according to the data attribute information input by the searcher, such as signal attribute, ECU attribute and network attribute associated with the data matrix, which is beneficial for understanding and horizontal comparison of the matrix information in the development process, so as to make a favorable decision. Clear or fuzzy search can also be realized.

[0072] In some examples, the method further includes:

[0073] According to the data attribute call frequency of the plurality of data attribute information;

[0074] In the case where the attribute call frequency exceeds the preset call frequency, a feature database is created on the server side for the attribute call frequency exceeding the preset call frequency.

[0075] For example, the database counts the data attribute call frequency according to the data attribute information of the plurality of search information, and if the attribute call frequency exceeds the preset call frequency, that is, the frequency of calling the attribute is high, a feature database exceeding the preset call frequency is established at this time, so that subsequent calling of the attribute does not need to be searched again, but directly calls the data in the feature database, thereby shortening the call cycle and improving the call efficiency.

[0076] In some examples, as Figure 4 shown, the method includes:

[0077] ① The demand side proposes the communication matrix demand, and the change involves the party confirms; ② After the change involves all parties confirm, the process flows to the communication matrix developer audit; ③ As long as there is a related CR (Change Request, change request) submission, the communication designer can know the CR information synchronously, and understand the CR details in advance, which is beneficial to the communication designer to understand the situation synchronously and evaluate; ④ The communication designer checks and adjusts, and only when the ② process is completed, the communication designer can go down (or agree, or return to the demand side); ⑤ Confirm whether the CR is executed.

[0078] It should be noted that the related information of the CR is stored in the temporary database on the server side, and when the CR process is normally completed (to ⑤ confirm completion), the matrix change data is updated in the database and can be viewed synchronously.
