In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0025] See also Figure 1 In one embodiment of the present invention, the present invention provides a multi-map application management system, including: a map interface 10, a navigation service 20 and a navigation interface 30; the map interface 10 is deployed in the map application 40 to receive map data and map status from the corresponding map application 40, and send the map data and map status to the navigation service 20; the navigation service 20 is used to receive the map data and map status of all map applications 40, and according to the priority of the competitive relationship corresponding to the map status of each map application 40, select the map interface 10 of the target map application corresponding to the map status with the highest competitive relationship priority to obtain the first target map data of the first target map application, and send the first target map data to the peripheral component 60 and / or the navigation interface 30; the navigation interface 30 is deployed in the vehicle-mounted application 50, and is used to send the received first target map data selected to be called by the navigation service 20 to the vehicle-mounted application 50.

[0026] In this embodiment, each map interface 10 is deployed in its corresponding map application 40. The map interface 10 is responsible for the interface definition of map-related capabilities, and after the interface is defined, each map application 40 implements specific functions. The map interface 10 can receive map data and map status from its corresponding map application 40, and further send the map data and map status to the navigation service 20. The navigation service 20 is responsible for managing each map application 40, and after receiving the map data and map status from each map application 40 through the map interface 10, according to the priority of the competitive relationship corresponding to the map status of each map application 40, find the map application 40 corresponding to the map status with the highest priority of the competitive relationship, and use the map application 40 corresponding to the map status with the highest priority of the competitive relationship as the first target map application to obtain the first target map data corresponding to the first map application. After the first target map data is acquired, it is further distributed to the peripheral component 60 or the navigation interface 30 through the navigation service 20, or it is sent to the vehicle application 50 through the navigation interface 30 and at the same time sent to the peripheral component 60 for use and display; after the navigation interface 30 receives the first target map data sent by the navigation service 20, it is further distributed to the vehicle application 50 for use. Through the above-mentioned multi-map application management system, it is possible to achieve unified management of various map applications 40 on the vehicle terminal and other devices, so as to better project the first target map data of the acquired first target map application to the navigation interface 30 to send to the vehicle application 50 or to the peripheral component 60, or it is sent to the vehicle application 50 through the navigation interface 30 and at the same time sent to the peripheral component 60 for use and display, so that there will be no confusion in the map application 40, thereby improving the user's driving experience. Specifically, the map application includes the default map application of the vehicle terminal and the map application on other devices, and the map application of other devices includes CarPlay, Android Auto, CarLink, etc.; the peripheral component 60 includes the instrument, HUD (head-up display), etc.; the vehicle application 50 includes voice, launch, etc. When the navigation service 20 sends the first target map data to the peripheral component 60, it can forward the first target map data fwk (Framework, a software development framework) to the peripheral component 60 through carpeoperty.

[0027] In one embodiment of the present invention, the map status includes the navigation map status, the foreground map status, the default map status and the background map status. The map status is in the order of high to low priority of the competitive relationship, namely, the navigation map status, the foreground map status, the default map status and the background map status.

[0028] In this embodiment, the map status of the map application 40 includes the map status in navigation, the foreground map status, the default map status and the background map status. And the highest priority of the competitive relationship is the map status in navigation, followed by the foreground map status, the default map status and the background map status. When determining which map application to use according to the map status of each map application 40, when there is a map application 40 in all the map applications 40 whose map status is the map status in navigation, and the map status of other map applications 40 are respectively in the foreground map status, the default map status and the background map status, then the map application 40 in the map status in navigation will be selected as the first target map application, and the first target map data of the first target map application will be sent to the peripheral component 60, and / or sent to the vehicle application 50 through the navigation interface 30.

[0029] In one embodiment of the present invention, the navigation service 20 is also used to call a map application 40 as a second target map application according to preset rules when the map status of all map applications 40 are the same, call the map interface 10 of the second target map application to obtain the second target map data of the second target map application, and send the second target map data to the peripheral component 60 and / or the navigation interface 30; the navigation interface 30 is used to send the received second target map data selected by the navigation service 20 to the in-vehicle application 50.

[0030] In this embodiment, when the navigation service 20 sends map data to the peripheral component 60 and / or the vehicle-mounted application 50, when the map status of all the map applications 40 is the same, one of the map applications 40 with the same map status will be selected as the second target map application according to a preset rule, and the map interface 10 of the second target map application will be selected to obtain the second target map data of the second map application to send to the peripheral component 60 and / or the navigation interface 30. The navigation interface 30 will further send the second target map data to the vehicle-mounted application 50 for use.

[0031] For example, when the map status of all map applications 40 is in the navigation map status, one of the map applications 40 will be selected and called as the second target map application in the navigation map status according to the preset rule. The preset rule can be to select one of the map applications 40 in the navigation map status as the second target map application according to the manual selection rule. Of course, it can also be that when a new map application 40 is in the navigation map status, the map application 40 in the navigation map status being used by the vehicle application 50 and / or the peripheral component 60 will be automatically closed accordingly, and the new map application 40 will be used as the second target map application, and the map interface 10 of the second target map application will be called to obtain the second target map data of the second target map application, and the second target map data will be sent to the peripheral component 60 and / or the navigation interface 30. Similarly, when the map status of all map applications 40 is in one of the map states of the foreground map state, the default map state and the background map state, a map application 40 is selected and called as the second target map application in the same way.

[0032] In one embodiment of the present invention, the navigation service 20 is also used to, when receiving a map application 40 in a navigation map state that is not executing the current navigation task, call the map application 40 in a navigation map state that is not executing the current navigation task as a third target map application, exit the navigation map state of the map application 40 that is executing the current navigation task, call the map interface 10 of the third target map application to obtain third target map data of the third target map application, and send the third target map data to the peripheral component 60 and / or the navigation interface 30; the navigation interface 30 is used to send the third target map data selected to be called by the received navigation service 20 to the in-vehicle application 50.

[0033] In this embodiment, when the navigation service 20 sends map data to the peripheral component 60 and / or the vehicle application 50, there is already a map application 40 sending its map data to the peripheral component 60 and / or the vehicle application 50, that is, when the map application 40 is in the process of executing the current navigation task, the map application 40 is in the navigation map state. When a new map application 40 enters the navigation map state and does not execute the current navigation task, that is, when the navigation service 20 receives the map application 40 in the navigation map state that does not execute the current navigation task, the map application 40 in the navigation map state that does not execute the current navigation task is used as the third target map application, and the map application 40 that executes the current navigation task before the third target map application exits the navigation map state. When calling the map application 40 in the navigation map state that does not execute the current navigation task as the third target map application, the third target map data of the third target map application is further obtained by calling the map interface 10 of the third target map application. Then the third target map data of the third target map application is sent to the peripheral component 60 and / or the navigation interface 30. After sending the third target map data to the navigation interface 30 , the navigation interface 30 will further send the received third target map data selected and called by the navigation service 20 to the in-vehicle application 50 for use.

[0034] In one embodiment of the present invention, each map application 40 monitors the current navigation focus in the vehicle through CarAppFocusManager (car application focus manager) and requests the navigation focus from the navigation service 20; the navigation service 20 is also used to assign the current navigation focus to the map application 40 that initiates the request when receiving the navigation focus request, so that the map application 40 that initiates the request initiates navigation; the map application 40 that loses the navigation focus exits the navigation state.

[0035] In this embodiment, during the map competition process, each map application 40 can monitor the current navigation focus of the vehicle through CarAppFocusManager and request the navigation focus from the navigation service 20 to determine whether it needs to exit the navigation state. That is, when a map application 40 initiates navigation, it will first initiate the navigation focus to the navigation service 20. When the map application 40 that initiated the request requests the navigation focus, it will monitor that the map application 40 that was originally in the navigation focus has lost the navigation focus, so that the map application 40 that has lost the navigation focus exits the navigation state.

[0036] In one embodiment of the present invention, the navigation service 20 includes: an interface calling module 21, a map management module 22 and a data sending module 23; the data sending module 23 is used to receive map data and map status sent by each map application 40 through the corresponding map interface 10; the map management module 22 is used to select the map interface 10 of the target map application corresponding to the map status with the highest competitive relationship priority to obtain the first target map data of the first target map application according to the competitive relationship priority corresponding to the map status of each map application 40; the interface calling module 21 is used to send the first target map data to the vehicle-mounted application 50 according to the received function call and parameter processing corresponding to the vehicle-mounted application 50.

[0037] In this embodiment, when the navigation service 20 sends the map data to the vehicle-mounted application 50, the data sending module 23 receives the map data and map status sent by each map application 40 through its corresponding map interface 10. Then, the map management module 22 finds the target map application corresponding to the map status with the highest priority of the competitive relationship as the first target map application according to the priority of the competitive relationship corresponding to the map status of each map application 40, and calls the first target map application to obtain the first target map data of the first target map application. The navigation interface 30 is used to connect the vehicle-mounted application to the navigation service 20 and call related functions; the interface calling module 21 receives the function call and parameter processing of the vehicle-mounted application to establish a mapping relationship between the navigation interface 30 and the map interface 10, so as to send the first target map data of the first target map application to the vehicle-mounted application 50 through the mapping relationship established between the navigation interface 30 and the map interface 10.

[0038] In one embodiment of the present invention, the map management module 22 includes: an interface scheduling module 221 and a map competition module 222; the map competition module 222 is used to select and call the map interface 10 of the target map application corresponding to the map state with the highest competition relationship priority according to the competition relationship priority corresponding to the map state of each map application 40; the interface scheduling module 221 is used to establish a mapping relationship between the navigation interface 30 of the vehicle-mounted application 50 and the map interface 10 selected and called by the map competition module 222.

[0039] In this embodiment, in the process of acquiring the first target map data of the first target map application, the map management module 22 selects to call the map interface 10 of the target map application corresponding to the map state with the highest priority of the competition relationship according to the competition relationship priority corresponding to the map state of each map application 40 through the map competition module 222. Then, according to the function call and parameter processing of the vehicle-mounted application received by the interface calling module 21, the navigation interface 30 of the vehicle-mounted application 50 is mapped with the map interface 10 selected to be called by the map competition module 222 through the interface scheduling module 221.

[0040] In one embodiment of the present invention, the map competition module 222 is used to manage the registration of map applications to the navigation service binder agent, and is also used to manage the map status of each map application 40, so as to select the map interface 10 of the target map application corresponding to the map status with the highest competition priority according to the competition relationship priority corresponding to the map status of each map application 40, wherein the competition relationship priority relationship of each map application 40 is: map status in navigation>foreground map status>default map status>background map status. Among them, the binder agent is a key object in a mechanism for implementing inter-process communication (IPC) in the Android system. The map interface 10 is the functional interface definition that the map application 40 needs to implement, and it is also the entry point for the navigation service to call the map function. The map application 40 can give the binder agent class to the navigation service through the map interface 10.

[0041] See also Figure 2 , the specific process of each map application 40 accessing the navigation service 20 provided by the present invention.

[0042] First, when the navigation service 20 is started, the default map application will be pulled up through the service, and the default map application will register the binder with the navigation service after it is started.

[0043] Next, when each map application 40 is started, it will register its own binder with the navigation service 20 through the map interface 10 (MapAPI).

[0044] Furthermore, when the navigation service 20 receives the binder registered by the map application, it caches the binder of each map application 40 and makes a mapping relationship between each map application 40 through the map identifier, so as to prepare for the subsequent post-competition map interface 10 call between the map applications 40.

[0045] See also Figure 3 , the present invention provides a contention and mutual exclusion processing flow when the map applications 40 are all in the navigation map state.

[0046] First, when map application A is opened and navigation is initiated, map application A will pass its navigation status to navigation service 20, which will save the navigation status of map A. In this state, map application A has the highest priority in terms of competition, and all interface requests of vehicle-mounted application 50 will be processed by map application A through the mapping relationship established between navigation interface 30 (NaviAPI) and map interface 10 of map application A. At the same time, map data (such as lane information, lane information, etc.) transmitted by map application A will be sent to navigation service 20 through its corresponding map interface 10, and navigation service 20 will further send it to peripheral components 60 and / or to vehicle-mounted application through navigation interface 30.

[0047] Next, when map application A is in the navigation state and map application B is opened, although map application B is opened but not in the navigation state, although map application B gives the foreground state to the navigation service 20, since it has not entered the navigation state, there will be no competition and mutual exclusion with map application A. At this time, a mapping relationship is still established through the map interface 10 corresponding to map application A and the navigation interface 30 of the vehicle-mounted application 40, and the map data received by the peripheral component 60 and / or the vehicle-mounted application 50 is still provided by map application A.

[0048] Furthermore, when map application B initiates navigation from the foreground state, it changes the map state to the navigation state and gives it to the navigation service 20. Since map application A is also in the navigation state at this time, it forms a competitive and mutually exclusive relationship with the navigation state of map application B, and since map application B is the map application 40 that initiates navigation later, the navigation service 20 will notify map application A to exit the navigation state.

[0049] Next, when map application A receives the instruction to cancel navigation, it will exit the navigation state and further give its non-navigation state to the navigation service 20.

[0050] Furthermore, when the navigation service 20 receives the non-navigation map state of the A map application, it will send a navigation cancellation instruction to the A map application, and will simultaneously update the locally cached map state. After the update, the competitive relationship of the B map application has the highest priority, and all interface requests of the vehicle-mounted application 50 will be processed by the B map application, and the map data received by the peripheral component 60 and / or the vehicle-mounted application 50 will be updated to the map data transmitted by the B map application.

[0051] Referring to 4, the present invention further provides a multi-map application management method, comprising the following steps:

[0052] Step S10: receiving map data and map status from the corresponding map application 40 through the map interface 10 deployed in the map application 40, and sending the map data and map status to the navigation service 20;

[0053] Step S20: receiving map data and map states of all map applications 40 through the navigation service 20, and selecting, according to the priority of the competitive relationship corresponding to the map states of the map applications 40, calling the map interface 10 of the target map application corresponding to the map state with the highest priority of the competitive relationship to obtain the first target map data of the first target map application, and sending the first target map data to the peripheral component 60 and / or the navigation interface 30;

[0054] Step S30 : sending the received first target map data selected and called by the navigation service 20 to the in-vehicle application 50 through the navigation interface 30 deployed in the in-vehicle application 50 .

[0055] In this embodiment, by deploying a map interface 10 in a map application 40 and a navigation interface 30 in a vehicle-mounted application 50, it is possible to uniformly manage multiple map applications 40 on vehicle-mounted terminals and other devices. The navigation service 20 obtains the first target map data of the first target map application corresponding to the map state with the highest priority of the competitive relationship according to the priority of the competitive relationship according to the map state, and sends the obtained first target map data to the vehicle-mounted application 50 and / or projects it to the peripheral component 60 for use and display, thereby making the vehicle-mounted navigation function more unified and reasonable, avoiding confusion in the map application 40, and improving the user's driving experience.

[0056] A multi-map application management method provided by the present invention also includes:

[0057] When the map status of all map applications 40 is the same, a map application 40 is called as the second target map application through the navigation service 20 according to preset rules, and the map interface 10 of the second target map application is called to obtain the second target map data of the second target map application, and the second target map data is sent to the peripheral component 60 and / or the navigation interface 30, so that the second target map data selected by the received navigation service 20 can be sent to the vehicle-mounted application 50 through the navigation interface 30.

[0058] In this embodiment, when the navigation service 20 sends the map data to the peripheral component 60 and / or the vehicle-mounted application 50, when the map status of all the map applications 40 is the same, one of the map applications 40 with the same map status is selected as the second target map application according to a preset rule, and the map interface 10 of the second target map application is selected to obtain the second target map data of the second map application to send to the peripheral component 60 and / or the navigation interface 30. The navigation interface 30 will further send the second target map data to the vehicle-mounted application 50 for use.

[0059] A multi-map application management method provided by the present invention also includes:

[0060] When the navigation service 20 receives a map application 40 that is in a navigation map state and is not executing the current navigation task, the navigation service 20 calls the map application 40 that is in a navigation map state and is not executing the current navigation task as a third target map application, exits the navigation map state of the map application 40 that is executing the current navigation task, calls the map interface 10 of the third target map application to obtain the third target map data of the third target map application, and sends the third target map data to the peripheral component 60 and / or the navigation interface 30, so that the navigation interface 30 is used to send the received third target map data selected to be called by the navigation service 20 to the in-vehicle application 50.

[0061] In this embodiment, when the navigation service 20 sends map data to the peripheral component 60 and / or the vehicle application 50, there is already a map application 40 sending its map data to the peripheral component 60 and / or the vehicle application 50, that is, when the map application 40 is in the process of executing the current navigation task, the map application 40 is in the navigation map state. When a new map application 40 enters the navigation map state and does not execute the current navigation task, that is, when the navigation service 20 receives the map application 40 in the navigation map state that does not execute the current navigation task, the map application 40 in the navigation map state that does not execute the current navigation task is used as the third target map application, and the map application 40 that executes the current navigation task before the third target map application exits the navigation map state. When calling the map application 40 in the navigation map state that does not execute the current navigation task as the third target map application, the third target map data of the third target map application is further obtained by calling the map interface 10 of the third target map application. Then the third target map data of the third target map application is sent to the peripheral component 60 and / or the navigation interface 30. After sending the third target map data to the navigation interface 30 , the navigation interface 30 will further send the received third target map data selected and called by the navigation service 20 to the in-vehicle application 50 for use.

[0062] In summary, the multi-map application management system and method disclosed in the present invention manages the various map applications 40 on the vehicle terminal and other devices in a unified manner, so as to better project the acquired target map data of the target map application to the navigation interface 30 to send it to the vehicle application 50 and / or project it to the peripheral component 60 for use and display, thereby making the vehicle navigation function more unified and reasonable, and avoiding the confusion of the map application 40, thereby improving the driving experience of the user. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.
