[0003] However, there are various third-party applications that need to use maps. At the same time, there are also cases where third-party applications on the same end, across different ends, and across different systems need to use the functions of map applications. Moreover, all third-party applications that use maps on the vehicle need to keep the displayed information consistent. Therefore, for different third-party applications to access the navigation service, the interfaces and methods will be continuously maintained in multiple sets according to the comprehensive requirements of the same end, across different ends, and across different systems, and the usage methods of each set of interfaces may also change. This leads to excessive maintenance content in the navigation service and inconsistent access methods.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0021] The navigation service communication method provided by the embodiments of the present invention is applied to a client and is mainly applicable to the case of unifying the interfaces between third-party applications and map applications. The navigation service communication method provided by the embodiments of the present invention can be executed by a vehicle-mounted device.

[0022] Figure 1It is a flowchart of a navigation service communication method provided by an embodiment of the present invention. Refer to Figure 1 This navigation service communication method is applied to a client, and specifically includes:

[0023] S110. Based on a target application in the client, determine the existence status of a target navigation service in the client.

[0024] Among them, the client is one end where the target application is installed, such as a vehicle-mounted device. The target application is a third-party application. When the target application is in use, it communicates with a map application and can use the functions of the map application. The map application and the target application can be installed on the same end or different ends. For example, the map application can also be installed on the vehicle-mounted device, or can be installed on a mobile terminal, a server, etc. The target navigation service is an intermediate service for the map application and the target application to access and use. One end of the target navigation service needs to be implemented by the map application, and the other end needs the target application that uses the map function to access and use according to its own needs, thus completing the construction of the communication bridge between the target application using the map and the map application. In this example, the target navigation service and the map application are installed on the same end. The existence status of the target navigation service includes existence and non-existence, and is used to describe whether the target navigation service exists in the client.

[0025] Specifically, start the target application in the client, and search the client through the function of searching for the target navigation service in the target application to determine whether the target navigation service exists in the client, that is, obtain the existence status of the target navigation service in the client.

[0026] Based on the above example, the following method can be used to determine the existence status of the target navigation service in the client based on the target application in the client:

[0027] Based on a target tool kit pre-configured in the target application, detect the client to determine the existence status of the target navigation service in the client.

[0028] Among them, the target tool kit is a software development kit (SDK) correspondingly configured with the target navigation service during the development of the target application, and is used to detect whether the target navigation service exists.

[0029] Specifically, start the target tool kit in the target application, and detect the system where the target application is located, that is, whether the target navigation application exists in the client, by executing the target tool kit.

[0030] It is understandable that the target toolkit can be integrated into the target application. The integration process includes: 1) Applying for an account for the open API (Open Application Programming Interface); 2) Logging in to the account on the portal website; 3) Creating an application and selecting the permissions supported by the target navigation service; 4) Integrating the license, relevant key, and token of the portal website into one's own application (the target application); 5) Introducing the jar package (Java file package) provided by the navigation service; 6) Initializing the jar package in the target application.

[0031] S120. Determine the relative application status between the target application and the map application according to the existence status.

[0032] Among them, the relative application status is used to describe whether the target application and the map application are on the same end and whether they are in the same system.

[0033] Specifically, in the case of obtaining the existence status of the target navigation service in the client, by analyzing the existence status, it can be determined whether the target navigation service and the target application are on the same end, that is, it can be determined whether the map application and the target application are on the same end. If they are on the same end, it can be considered to be in the same system. If they are on different ends, it can be further analyzed whether they are in the same system. Thus, the relative application status between the target application and the map application can be determined.

[0034] Based on the above example, the relative application status between the target application and the map application can be determined according to the existence status in the following manner:

[0035] In response to the existence status being "exists", determine that the relative application status is the same end and the same system;

[0036] In response to the existence status being "does not exist", obtain the first system type of the client and the second system type corresponding to the map application, and determine the relative application status according to the first system type and the second system type.

[0037] Among them, "the same end and the same system" means the same end and the same system. The first system type is the system type used by the client. The second system type is the system type used by the end where the map application is installed.

[0038] Specifically, if the existence status of the target navigation service in the client is "existent", it indicates that the target navigation service is located in the client, that is, the target navigation service and the target application are on the same side. Since the target navigation service and the map application are bound and installed on the same side, it can be considered that the target application and the map application are on the same side, and the systems used on the same side are the same system. Therefore, it can be determined that the relative application status is the same side and the same system. If the existence status of the target navigation service in the client is "non-existent", it means that the target navigation service is not located in the client, that is, the target navigation service and the target application are on different sides. Since the target navigation service and the map application are bound and installed on the same side, it can be considered that the target application and the map application are on different sides. Furthermore, it is necessary to analyze whether the target application and the map application are used based on the same system. Therefore, the first system type of the client and the second system type corresponding to the map application can be obtained, and it can be determined whether the first system type and the second system type are the same. Combining the judgment result and the determined different sides, the relative application status can be obtained, that is, different sides and the same system or different sides and different systems.

[0039] Based on the above example, the relative application status can be determined according to the first system type and the second system type in the following way:

[0040] In response to the first system type being the same as the second system type, it is determined that the relative application status is different sides and the same system;

[0041] In response to the first system type being different from the second system type, it is determined that the relative application status is different sides and different systems.

[0042] Specifically, if the first system type is the same as the second system type, it means that the target application and the map application are used based on the same system, and the same system can be determined. Furthermore, it can be determined that the relative application status is different sides and the same system. If the first system type is different from the second system type, it means that the target application and the map application are used based on different systems, and different systems can be determined. Furthermore, it can be determined that the relative application status is different sides and different systems.

[0043] S130. Determine the target communication method between the target application and the map application according to the relative application status.

[0044] Among them, the target communication method is the communication protocol used for communication between the target application and the map application.

[0045] Specifically, according to the relative application status, determine to use the communication protocol of the same side or the cross-side communication protocol as the communication protocol used for communication between the target application and the map application, that is, the target communication method.

[0046] Based on the above examples, the target communication method includes an in - terminal communication protocol and a cross - terminal communication protocol. Accordingly, the target communication method between the target application and the map application can be determined according to the relative state of the application in the following manner:

[0047] In response to the relative state of the application being in - terminal and within the same system, obtain the first system type of the client, and determine the in - terminal communication protocol according to the first system type;

[0048] In response to the relative state of the application being different - terminal and within the same system or different - terminal and different systems, obtain the first system type and the second system type corresponding to the map application, and based on the distributed file system, determine the cross - terminal communication protocol according to the first system type and the second system type.

[0049] Among them, the in - terminal communication protocol is a communication protocol based on the first system type, which is used to realize data exchange under the first system type. The distributed file system is usually used to handle the storage and management of large - data and complex data types. In DFS (Distributed File System), cross - node and cross - terminal communication is automatic because the design purpose of DFS is to effectively transfer and store data between multiple computers. DFS is a way of data communication between different systems implemented in the system layer and the driver layer in C++. The cross - terminal communication protocol is a communication protocol determined based on the capabilities of the distributed file system.

[0050] Specifically, if the relative state of the application is in - terminal and within the same system, it means that for in - terminal and within - the - same - system information transmission, it is necessary to obtain the first system type of the client, and according to the first system type, determine a corresponding in - terminal communication protocol from each in - terminal communication protocol. If the relative state of the application is different - terminal and within the same system or different - terminal and different systems, it is necessary to analyze the system type, determine the interface type, and then determine the target communication method. Therefore, obtain the first system type and the second system type corresponding to the map application, and based on the distributed file system, automatically search according to the first system type and the second system type to determine a cross - terminal communication protocol that matches the first system type and the second system type.

[0051] Exemplarily, if it is considered that the map application and the target application are in - terminal and the system is android, data exchange can be directly realized through the aidl (Android Interface Definition Language) capability provided by the android system, and the in - terminal communication protocol corresponding to android is determined. If it is considered that the map application and the navigation application are not in the same terminal, the DFS capability provided by the underlying layer is used to realize cross - terminal communication, and the cross - terminal communication protocol corresponding to the same system or different systems is determined.

[0052] Based on the above examples, after determining the target communication method between the target application and the map application according to the relative state of the application, the target application can also control the map application. Specifically, it can be:

[0053] Based on the target application, send a control instruction to the target navigation service through the target communication method, so that based on the first system type of the client and the second system type corresponding to the map application by the target navigation service, the control instruction is forwarded to the map application.

[0054] Among them, the control instruction is an instruction for the target application to control the map application.

[0055] Specifically, the target application can send the control instruction to the target navigation service through the target communication method. After receiving the control instruction, the target navigation service performs the conversion of the instruction and data, so that the control instruction corresponding to the first system type is converted into the control instruction corresponding to the second system type, and the control instruction of the second system type is sent to the map application, so that the map application can respond to the converted control instruction.

[0056] Exemplarily, for the target navigation service, the control instruction, such as the instruction and data, is transferred to the map application located at the same system end for processing, and then the map application gives a corresponding feedback, and then the feedback is forwarded to the target application in the client where each target application is located.

[0057] Based on the above examples, the control instruction includes an application call instruction and a navigation operation instruction. The map application is used to execute the call operation corresponding to the application call instruction when receiving the application call instruction, and determine and display the target navigation information based on the navigation target corresponding to the navigation operation instruction.

[0058] Among them, the call instruction is an instruction for calling and starting the map application. The call operation is an operation for calling and starting the map application. The navigation operation instruction is an instruction for performing navigation path planning. The navigation target is the information required for performing the navigation operation, such as the starting point, the ending point, the transportation mode, etc. The target navigation information is the result information of executing the navigation operation instruction.

[0059] Specifically, the target application sends the retrieval instruction and the navigation operation instruction to the map application via the target navigation service using the target communication method. When the map application receives the retrieval instruction, it parses the instruction to determine the retrieval operation, that is, to call and start the map application. Then, the map application executes the retrieval operation to complete the retrieval instruction. Further, when the map application receives the navigation operation instruction sent by the target application via the target navigation service using the target communication method, it parses the instruction to obtain the navigation target carried by the navigation operation instruction. The map application performs navigation operations according to the navigation target to obtain the navigation result information, that is, the target navigation information. Optionally, if it is necessary to display the target navigation information on the target application, the target navigation information can be fed back to the target application via the target navigation service using the target communication method and displayed thereon.

[0060] Based on the above example, the control instruction includes an information reading instruction. The map application is used to determine the target information from each piece of existing information stored in advance according to the information reading instruction and feed back the target information to the target application.

[0061] Among them, the information reading instruction is an instruction to retrieve and forward the information stored in the map application. The existing information is the information stored in advance in the map application, such as the frequently used address information stored when the user uses the map application, etc.

[0062] Specifically, the target application sends the information reading instruction to the map application via the target navigation service using the target communication method. When the map application receives the information reading instruction, it parses the instruction to determine the requirements corresponding to the information reading instruction, searches from each piece of existing information stored in advance in the map application according to the requirements, and obtains the target information. Then, the target information is fed back to the target application via the target navigation service using the target communication method to complete the operation corresponding to the information reading instruction.

[0063] Based on the above example, the map application is also used to determine the actively transmitted information and send the actively transmitted information to the target navigation service using the target communication method.

[0064] Among them, the actively transmitted information is the information actively transmitted by the map application to the target navigation service.

[0065] Specifically, when the map application can perform data transmission with the target application through the target communication method, in addition to passively executing the operations required by the target application and reading the information required by the target application, it can also actively send information to the target navigation service, and the target application listens to these actively transmitted information in the target navigation service to obtain the required information. It can be seen that various types of information that the map application can store are used as actively transmitted information. After determining the target communication method and the map application is launched by the target application, the actively transmitted information is sent to the target navigation service through the target communication method.

[0066] Exemplarily, a navigation service application (target navigation service) can be integrated in the in-vehicle system (client) of any vehicle model. The target navigation service is a resident service program running in the in-vehicle system. In the in-vehicle system, the application program of the target application uses the interface provided by the navigation service application to access and implement the target functions. The target functions include functions related to navigation such as opening / closing the map application, starting navigation planning, querying and searching for location point information, etc. In the in-vehicle system, a third-party application (target application) that needs to use the functions of the map application needs to integrate the navigation service. After the target application is successfully initialized, it can normally call the interface provided by the target navigation service to implement navigation-related functions. For example: perform an init() instruction (initialization) through the Navi Api (navigation interface). In the init(), it will be judged whether the target application and the map application belong to the same end or cross-end, and the same system or cross-system. The judgment methods include:

[0067] 1) Detect whether there is a navigation service application (target navigation service) in the system where the target application is located;

[0068] 2) If it exists, it is considered that the map application and the target application are on the same end. Then, according to the system, the target communication method can be determined. For example, data exchange can be directly implemented through the aidl capability provided by the android system;

[0069] 3) If it does not exist, it is considered that the map application and the target application are not on the same end, and the DFS capability provided by the underlying layer is used to implement cross-end communication;

[0070] 4) Whether it is cross-system or not, for the target navigation service, the instructions and data are both transferred to the map application on the same system end for processing, and then the map application gives a corresponding feedback. Then, the feedback is forwarded to the target application of the client of each system.

[0071] Then, record the target communication methods between each target application and the map application. When actually using the interface later, the usage methods of the same-end and cross-end system interfaces are the same, but internally, the recorded flag bits will be used to determine whether the current proxy interface uses the same-end communication scheme or the cross-end communication scheme. In the same-end system, the same-end communication link will be used. For example, at this time, the aidl communication function provided by Android is used to implement information interaction. In the cross-end system, the cross-end communication link will be used at this time, and the cross-end communication interface provided by the system can be used to implement information interaction.

[0072] Through the above technical solution, in the form of a unified interface and communication protocol, it is more convenient for the target application using the map to access the target navigation service. At the same time, the workload of maintaining multiple sets of interfaces internally in the target navigation service is reduced. For the target navigation service, there is no need to maintain multiple sets of interfaces, and only one set needs to be maintained for the same-end, cross-end, cross-system, etc. interfaces, which greatly reduces the interface maintenance work. For the target application using the map application, there will be no confusion due to inconsistent access methods for cross-end, cross-system, etc., improving the access efficiency of the user.

[0073] The present invention has the following technical effects: By determining the existence status of the target navigation service in the client based on the target application in the client, determining the relative application status of the target application and the map application according to the existence status, and determining the target communication method between the target application and the map application according to the relative application status, the effect of a unified communication interface and reduced interface maintenance cost is achieved, and the usability of the target application using the map application is improved.
