Wherein, the second knowledge graph under the model node means that the second knowledge graph is subordinate to the model node, in other words, the second knowledge graph is the knowledge graph of the next level of the model node. The service node corresponds to the service provided by the target service platform, such as navigation service, multimedia playing service, vehicle detection service and the like. A functional system refers to a collection of hardware in a vehicle that is required to implement a particular function, e.g., implementation of a navigation function depends on the navigation function system.

The foregoing steps 202-206 are simple descriptions of the technical solutions provided in the embodiments of the present application, and the following will be described in more detail with reference to fig. 3 by taking an execution subject as an example, where the method includes the following steps.

302. The terminal displays a service platform selection interface, and a plurality of candidate service platforms are displayed in the service platform selection interface.

The service platform selection interface is used for selecting different service platforms for viewing, for example, a vehicle manufacturer may construct one service platform to provide services for different vehicle types, or may directly cooperate with a third party service platform, so that services provided by the third party service platform are directly used. In some embodiments, the vehicle manufacturer may cooperate with multiple third party service platforms to utilize the dominant service projects of different third party service platforms to improve the performance of the produced vehicle, wherein the multiple candidate service platforms are multiple third party service platforms, and the target service platform which wants to view the association relationship can be selected from the multiple candidate service platforms through the service platform selection interface.

In one possible implementation, in response to a viewing operation of the service platform selection interface, the terminal displays the service platform selection interface, in which icons of the plurality of candidate service platforms are displayed.

It should be noted that, the above step 302 is an optional step, and the terminal may perform the above step 302 or may directly perform the following step 304, which is not limited in this embodiment of the present application.

304. And under the condition that the target service platform in the plurality of candidate service platforms is selected, the terminal displays a first knowledge graph of the target service platform, wherein the first knowledge graph comprises a target service platform node and a plurality of vehicle type nodes, and the first knowledge graph is used for displaying the association relation between the target service platform node and the plurality of vehicle type nodes.

The first knowledge graph shows the association relationship between the target service platform node and the plurality of vehicle model nodes, namely, the association relationship between the target service platform and the plurality of vehicle models is shown, and a technician can intuitively acquire the association relationship through the first knowledge graph. In some embodiments, the first knowledge graph includes two types of nodes, namely a target service platform node and a vehicle type node, where the two types of nodes are represented by a connection line, for example, when a connection line exists between the target service platform node and a vehicle type node, the first knowledge graph indicates that the target service platform node and the vehicle type node have a connection line, and thus the target service platform provides services for a vehicle type corresponding to the vehicle type node.

In one possible implementation manner, in a case that the target service platform in the plurality of candidate service platforms is selected, the terminal acquires a plurality of vehicle types having an association relationship with the target service platform. The terminal generates a target service platform node corresponding to the target service platform and a plurality of vehicle type nodes corresponding to the plurality of vehicle types respectively, wherein the name of the target service platform node is the name of the target service platform, and the name of the vehicle type node is the name of the corresponding vehicle type.

For example, if the target service platform in the plurality of candidate service platforms is selected, the terminal sends an associated vehicle type acquisition request to the server, where the associated vehicle type acquisition request carries an identifier of the target service platform, and the server is a data server set up by a vehicle manufacturer. The server receives the associated vehicle type acquisition request and acquires the identification of the target service platform from the associated vehicle type acquisition request. The server queries based on the identification of the target service platform to obtain a plurality of vehicle types with association relations with the target service platform. The server sends the multiple vehicle models to the terminal, and the terminal acquires the multiple vehicle models. The terminal generates a target service platform node corresponding to the target service platform and a plurality of vehicle type nodes corresponding to the plurality of vehicle types respectively, and based on the association relationship between the target service platform and the plurality of vehicle types, a connecting line is added between the target service platform node and the plurality of vehicle type nodes to obtain the first knowledge graph. And the terminal displays the first knowledge graph. For example, referring to fig. 5, the terminal displays a first knowledge graph 500, the first knowledge graph 500 including a target service platform node 501 and a plurality of model nodes 502-505. In some embodiments, the target service platform node is located in the center of the first knowledge graph, and the plurality of vehicle model nodes encircle the target service platform node.

In the foregoing description, the first knowledge-graph is generated by the terminal as an example, and in other possible embodiments, the first knowledge-graph may be generated by a server, which is not limited in this embodiment of the present application.

In some embodiments, to distinguish between the connection between the target service platform node and the model node and between the model nodes, the terminal can display the connection with different colors, for example, the color of the connection between the target service platform node and the model node is black, and the color of the connection between the model nodes is red. The association relationship between the model nodes comprises a substitution relationship of the model corresponding to the model nodes, for example, the model A is a precursor of the model B, a connecting line exists between the model nodes corresponding to the model A and the model B in the first knowledge graph, in some embodiments, the connecting line between the model nodes is a directional line segment, the substitution relationship between the model nodes corresponding to the model can be intuitively displayed through the direction of the directional line segment, and the efficiency of man-machine interaction is improved.

Optionally, after the terminal displays the first knowledge-graph, the terminal is further capable of performing any one of the following steps.

In one possible implementation, an export control is displayed in the first knowledge-graph, and the terminal exports the first knowledge-graph as an image in response to a click operation on the export control.

Under the implementation mode, the export control is provided on the first knowledge graph, and the first knowledge graph can be exported into the image through the export control, so that the storage and the sharing are facilitated, and the efficiency of man-machine interaction is improved.

In the case where the storage location of the image is selected by the storage location selection area, the terminal derives the first knowledge-graph as the image in response to a click operation on the confirmation control. In some embodiments, the image export popup further comprises at least one of an export image preview area for previewing the first knowledge-graph and a naming area for naming the exported image.

In one possible implementation, the first knowledge-graph is displayed with a zoom-in control, and the terminal zooms in on the first knowledge-graph in response to a click operation on the zoom-in control. In some embodiments, the graphs in the first knowledge-graph are vector graphs, so that the first knowledge-graph still has higher definition after amplification.
