[0045] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0046] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0047] The navigation data transmission method provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0048] Figure 1 The present invention is a flowchart of a navigation data transmission method according to an exemplary embodiment. The navigation data transmission method is applied to a navigation service in a vehicle-mounted system, and includes the following steps:

[0049] Step S11: receiving status information sent by any navigation application; the status information is used to indicate the running status of any navigation application.

[0050] Ecological applications such as weather, desktop, multimedia, and multiple navigation applications that can provide navigation functions will be installed in the vehicle system. In some cases, ecological applications need to obtain navigation data provided by navigation applications. For example, the desktop can initiate navigation, the weather can obtain longitude and latitude from the navigation, and the voice can obtain surrounding geographic information from the navigation, thereby enriching the navigation experience.

[0051] In the related art, the transmission of navigation data is difficult to adapt to multiple navigation scenarios, making it difficult to apply multiple navigation scenarios on a large scale in vehicle-mounted systems. Therefore, in order to provide better navigation services, a navigation data transmission method for navigation services applied to vehicle-mounted systems is proposed in this application to solve the above problems.

[0052] Among them, the navigation service is a background service application pre-installed in the vehicle system, which is responsible for connecting the ecological applications and navigation applications installed in the vehicle system.

[0053] First, in this step, it is necessary to receive status information sent by any navigation application, wherein the status information is used to indicate the running status of any navigation application, that is, the navigation application will actively send its own status information to the navigation service to notify the navigation service of its own running status.

[0054] In the vehicle system, the running status of each navigation application may include navigation status, foreground running, background running and closed status. Among them, the navigation status means that the current navigation application is navigating, the foreground running means that the application interface of the current navigation application is being displayed on the screen, the background running means that the application interface of the current navigation application is not displayed on the screen, and the closed status means that the current navigation application has exited navigation.

[0055] It can be understood that when multiple navigation applications are installed in the vehicle system, the operating status of each navigation application can change in response to the user's operating instructions, and after the operating status changes, the status information is sent to the navigation service. Alternatively, each navigation application can also periodically send status information to the navigation service at a preset time interval. This application does not specifically limit this.

[0056] Step S12: Determine the first priority of any navigation application according to the status information.

[0057] In this step, the navigation service can determine the first priority of each navigation application based on the status information of the navigation application, wherein the first priority can indicate the priority relationship of each navigation application. Furthermore, in subsequent steps, the transmission path of navigation instructions and navigation data can be determined based on the first priority of each navigation application.

[0058] In one implementation, determining the first priority of any navigation application according to the state information includes:

[0059] When the status information indicates that any navigation application is in the navigation state, the first priority of any navigation application is determined as the first level, and the first priority of other navigation applications except any navigation application is determined as the corresponding preset default level; wherein the first level is higher than the preset default level.

[0060] That is to say, if the status information indicates that a navigation application is in the navigation state, which means that the navigation application is currently navigating and collecting the vehicle's navigation data, then the navigation service can determine the first priority of the navigation application as the first level, and at the same time, determine the first priority of other navigation applications other than the navigation application as the corresponding preset default level.

[0061] The first level is the highest level in the first priority level, which is higher than the preset default level of each navigation application. In the present application, each navigation application in the vehicle system has its corresponding preset default level, which is used to indicate the default priority of each navigation application and can be determined according to the user's pre-settings. The preset default levels of each navigation application can be the same or different, and there is no specific limitation.

[0062] In other words, if a navigation application is in the navigation state, then the first priority of the navigation application is the first level, which is the highest first priority among all current navigation applications.

[0063] In one implementation, before determining the first priority of other navigation applications except any navigation application as the corresponding preset default level, the method further includes:

[0064] In the case where the state information indicates that any navigation application is in a navigation state, determining whether there is a mutually exclusive navigation application at the current moment, where the mutually exclusive navigation application is another navigation application in a navigation state except for any navigation application;

[0065] If it exists, a notification message is sent to the mutually exclusive navigation application; the notification message is used to prompt the mutually exclusive navigation application to exit the navigation state.

[0066] That is, when the navigation service determines that the state information indicates that a navigation application is in the navigation state, it can further determine the running state of other navigation applications other than the navigation application, and determine whether there are other mutually exclusive navigation applications in the navigation state. If there are, the navigation service can send a notification message to the mutually exclusive navigation application to prompt the mutually exclusive navigation application to exit the navigation state.

[0067] In this way, it can be ensured that only one navigation application is in the navigation state at the same time, thereby avoiding navigation conflicts among various navigation applications and reducing the occupation of system resources by navigation applications.

[0068] Among them, after receiving the notification message, the mutually exclusive navigation application can change its own running state to background running or closed state, and this application does not make any specific restrictions on this.

[0069] In one implementation, determining the first priority of any navigation application according to the state information further includes:

[0070] When the status information indicates that any navigation application is running in the foreground, obtaining the second priority of each navigation application at the current moment;

[0071] If there is no navigation application whose second priority is the first level, the first priority of any navigation application is determined as the second level, and the first priority of other navigation applications except any navigation application is determined as the corresponding preset default level; wherein the first level is higher than the second level, and the second level is higher than the preset default level.

[0072] That is, if the status information indicates that a certain navigation application is running in the foreground, which means that the application interface of the navigation application is being displayed on the screen, then the navigation service can obtain the second priority of each navigation application at the current moment.

[0073] Among them, the second priority and the first priority are also used to indicate the priority relationship between each navigation application. For the convenience of description, in this application, the priority of each navigation application at the current moment is referred to as the second priority, and the priority of each navigation application after updating based on the status information is referred to as the first priority.

[0074] If there is no navigation application with the second priority of the first level at the current moment, the first priority of the navigation application running in the foreground is determined as the second level, and the first priorities of other navigation applications except the navigation application are determined as the corresponding preset default levels, wherein the first level is higher than the second level, and the second level is higher than the preset default level.

[0075] In other words, if a navigation application is running in the foreground and there is no navigation application in the navigation state, the first priority of the current navigation application is the second level, which is the highest first priority among all navigation applications. However, the second level is lower than the first level, so if the running state of other navigation applications is switched to the navigation state, the corresponding first priority will also become the first level, which will be higher than the first priority of the current navigation application.

[0076] In one implementation, after obtaining the second priority of each navigation application at the current moment, the method further includes:

[0077] If there is a navigation application whose second priority is the first level, the first priority of any navigation application is the same as the second priority.

[0078] That is to say, in another case, if there is a navigation application whose second priority is the first level at the current moment, for example, if the second priority of the navigation application running in the foreground at the current moment is the first level, or if the second priority of other navigation applications is the first level, then the first priority of the navigation application running in the foreground at the current moment can be determined to be the same as its second priority, that is, the priority of the navigation application running in the foreground at the current moment does not change.

[0079] In other words, if a navigation application is running in the foreground, but there is a navigation application currently in the navigation state, the first priority of each navigation application does not change, and the vehicle is still navigated by the first-level navigation application at the current moment.

[0080] In one implementation, determining the first priority of any navigation application according to the state information further includes:

[0081] When the status information indicates that any navigation application is running in the background, it is determined that the first priority of any navigation application is the same as the second priority of any navigation application at the current moment.

[0082] That is to say, if the status information indicates that a navigation application is running in the background, which means that the application interface of the navigation application is not displayed on the screen, then the navigation service can determine the first priority of the navigation application running in the background at the current moment to be the same as its second priority, that is, the priority of the navigation application running in the background at the current moment does not change.

[0083] In other words, for a navigation application that is switched to run in the background, its first priority usually does not change, thereby avoiding multiple openings and conflicts of various navigation applications.

[0084] In one implementation, determining the first priority of any navigation application according to the state information further includes:

[0085] When the status information indicates that any navigation application is in a closed state, the first priority of any navigation application is determined to be the corresponding preset default level.

[0086] That is, if the status information indicates that a navigation application is in a closed state, indicating that the navigation application has exited navigation, then the navigation service may determine the first priority of the navigation application as the corresponding preset default level.

[0087] In one implementation, the navigation application includes a default navigation application and at least one candidate navigation application, wherein:

[0088] The preset default level corresponding to the default navigation application is the third level, and the preset default level corresponding to the candidate navigation application is the fourth level, and the third level is higher than the fourth level.

[0089] In the present application, the navigation application may include a default navigation application and at least one candidate navigation application, wherein the preset default level corresponding to the default navigation application is the third level, and the preset default level corresponding to the candidate navigation application is the fourth level, and the third level is higher than the fourth level, that is, the preset default level corresponding to the default navigation is higher than the preset default level corresponding to the candidate navigation application.

[0090] In this way, when the first priorities of various navigation applications are corresponding to the preset default levels, the default navigation application can still be determined according to the first priority, and then the default navigation application processes the navigation instructions of the ecological application, thereby realizing the transmission of navigation data.

[0091] Step S13: receiving a navigation instruction sent by any ecological application, sending the navigation instruction to a target navigation application, and sending navigation data returned by the target navigation application to any ecological application; wherein the target navigation application is a navigation application with the highest first priority.

[0092] In this step, after receiving the navigation instruction sent by any ecological application, the navigation service can determine the navigation application with the highest first priority as the target navigation application, and then send the navigation instruction to the target navigation application, which processes the navigation instruction and sends the navigation data returned by the target navigation application to the corresponding ecological application. In this way, the transmission of navigation data between ecological applications and navigation applications is realized.

[0093] In one implementation, before receiving the status information sent by any navigation application, the method further includes:

[0094] Establish communication connection with each navigation application based on cross-process communication technology;

[0095] Before receiving navigation instructions sent by any ecological application, it also includes:

[0096] Based on cross-process communication technology, establish a communication connection with each ecological application.

[0097] That is to say, in this application, based on IPC (Inter-Process Communication) technology, communication connections can be established between ecological applications and navigation services, and between navigation applications and navigation services. Among them, IPC technology can realize the process of data exchange between two processes. IPC technology allows different processes to interact through specific communication protocols and mechanisms, thereby achieving purposes such as resource sharing and task collaboration.

[0098] Specifically, AIDL (Android Interface Definition Language) can be used to implement IPC technology. AIDL technology is widely used in Android development and can realize data sharing and communication between multiple processes, facilitating modular development and function expansion. Common application scenarios include remote service calls and cross-process data transmission.

[0099] AIDL is based on RPC (Remote Procedure Call) and defines an interface description language for describing service interfaces and methods. Through AIDL, users can define their own interfaces and expose them to other processes through the Binder mechanism. Then, other processes can obtain the proxy object of the service to implement cross-process interface calls.

[0100] Using AIDL technology requires the following steps:

[0101] First, define the AIDL interface: define the AIDL interface on the service provider, including the methods and data types that need to be exposed; then, implement the AIDL interface: implement the AIDL interface on the service provider and use it as part of the service; then, obtain the proxy object: obtain the proxy object of the AIDL interface on the service consumer, which is used to call the interface methods across processes; finally, call the remote method: use the proxy object to call the AIDL interface method to implement cross-process calling.

[0102] like Figure 2 As shown, it is a system architecture diagram of the navigation data transmission method provided in this application, and the system architecture includes ecological applications, navigation services and navigation applications.

[0103] Among them, ecological applications include various applications such as weather, desktop, multimedia, including application A, application B, application C, etc.; navigation applications include navigation applications with various navigation functions provided by navigation manufacturers, including navigation A, navigation B, navigation C, etc., among which navigation A is the default navigation application, that is, the preset default priority of navigation A is higher than other navigation applications; navigation service is a background service application pre-installed in the vehicle system, which is responsible for connecting ecological applications and navigation applications.

[0104] Ecological applications can send navigation instructions to navigation applications through navigation services and use navigation-related capabilities of navigation applications. For example, navigation instructions may include but are not limited to: initiating navigation, searching nearby, obtaining geographic information, stopping navigation, and obtaining vehicle speed;

[0105] Then, the navigation service can conduct navigation competition, that is, determine the first priority of each navigation application according to the status information of each navigation application, and realize the mutual exclusion of each navigation application, etc.; in this way, the instructions issued by the ecological application can only be executed by the highest priority navigation application at the same time, and only the highest priority navigation application can return navigation data to the navigation service, and further forwarded by the navigation service to the ecological application. For example, the navigation data may include but is not limited to: road information, navigation status, vehicle speed, traffic lights, speed limit information.

[0106] As can be seen from the above, the technical solution provided by the embodiment of the present application manages the first priority of each navigation application, determines the target navigation application with the highest first priority from multiple navigation applications, and has the target navigation application process the navigation instructions sent by the ecological application, so that each navigation application in multiple navigation scenarios can transmit data in an orderly manner. Among them, the navigation service in the vehicle system is used as the middle layer to connect the ecological application and the navigation application, which can greatly reduce the development and adaptation costs. Moreover, this solution is a pure application layer development, does not require the underlying system access, is simple to implement, and is easy to maintain, thereby meeting the application requirements of multiple navigation scenarios.

[0107] The navigation data transmission method provided in the embodiment of the present application may be executed by a navigation data transmission device. In the embodiment of the present application, a method in which a navigation data transmission device executes terminal access is taken as an example to illustrate the device of the navigation data transmission method provided in the embodiment of the present application.
