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.

For example, the terminal displays a function selection interface in which a service platform selection control is displayed. And responding to clicking operation of the service platform selection control, displaying the service platform selection interface by the terminal, and displaying the icons of the candidate service platforms on the service platform selection interface in a tiled mode. For example, referring to fig. 4, the terminal displays a function selection interface 400, and a service platform selection control 401 is displayed in the function selection interface 400. In response to the clicking operation on the service platform selection control 401, the terminal obtains interface display data corresponding to the service platform selection control 401, where the interface display data includes interface elements and an arrangement mode of the interface elements. The terminal displays the service platform selection interface 402 based on the interface display data, the service platform selection interface 402 including icons 403-406 of a plurality of candidate service platforms.

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 entity corresponding to the target service platform node is a target service platform, and the target service platform is a selected service platform. The entity corresponding to the plurality of vehicle type nodes is a plurality of vehicle types, the relationship between the vehicle type nodes and the vehicle types is one-to-one correspondence, and the plurality of vehicle types are all vehicle types served by the target service platform. 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. The terminal adds a connecting line between the target service platform node and the plurality of vehicle type nodes based on the association relation between the target service platform and the plurality of vehicle types to obtain the first knowledge graph, and the terminal displays the first knowledge graph. The relevance between the service platform and the vehicle model is stored in the cloud in advance so that the terminal can call the relevance at any time, wherein the cloud refers to the target service platform or a data server maintained by a vehicle enterprise, and the application embodiment is not limited to the relevance.
In the embodiment, the terminal can generate the first knowledge graph based on the target service platform after selecting the target service platform, the first knowledge graph does not need to be generated in advance, the occupation of the storage space is reduced, and meanwhile, the first knowledge graph generated in real time has higher flexibility.
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.
