[0002] As the automotive industry has become a pillar of my country's national economic development, the integration of automotive technology and technical information has made automotive electronics an independent industry. Consequently, in-vehicle navigation systems have become essential equipment in vehicles. The primary functions of in-vehicle navigation systems are positioning, monitoring, and navigation. Maps are the core software in the in-vehicle navigation software ecosystem. Typically, in-vehicle navigation software comes in a variety of map packages, and in-vehicle devices on the market often have multiple map software installed for navigation. However, the multiple map software packages often lead to the problem of how to select the right one.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] It should be noted that terms such as "target" in the description, claims, and above-mentioned drawings of the present invention are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0031] In one embodiment, Figure 1 is a flowchart of a map navigation method provided by an embodiment of the present invention. This embodiment is applicable to the situation of obtaining a focus map from multiple map software for navigation in the case of multiple map software. This method can be executed by a map navigation device, and the map navigation device can be implemented in the form of hardware and / or software. As Figure 1 shown, the method includes:

[0032] S110. Start map navigation according to the preset trigger condition of the target vehicle.

[0033] Among them, the preset trigger condition can be understood as the trigger condition for the navigation service system to start the corresponding map for navigation. The preset trigger condition can be related trigger conditions such as user voice instructions, user text instructions, etc., or can also be the instruction condition for the vehicle to actively trigger navigation. This embodiment does not limit this here.

[0034] In this embodiment, there are various ways to start map navigation according to the preset trigger condition of the target vehicle. In some embodiments, corresponding map navigation can be started by voice, text, steering wheel control, etc. input by the user, or corresponding map navigation can be started by the target vehicle actively sending corresponding map data during driving; in other embodiments, it can also be started by pre-timing to start map navigation at a specified time. This embodiment does not limit this here. It should be noted that when starting map navigation, at least one map navigation is started.

[0035] S120. Determine the map status and map display environment of the target vehicle.

[0036] Among them, the map status can be understood as the map status corresponding to each map navigation software in the vehicle. The map display environment can be understood as the device environment for map display on the display end of the vehicle, which can be a head-up display, an in-vehicle instrument display, etc.

[0037] In this embodiment, the map state can be that the current map is in a map navigation state, the current map is in a map cruise state, the current map is in a map front state, or the current map is in a map background state, and this embodiment does not limit this. The map display environment in this embodiment can include the main screen display of the vehicle display terminal and the secondary screen display of the vehicle display. If the map display environment on the vehicle can be split, the map display environment can also include the left screen of the vehicle display split, the right screen of the vehicle display split, etc.

[0038] In this embodiment, the map status and map display environment corresponding to the vehicle can be collected and obtained in sequence. The acquisition order in this embodiment is not limited. In some embodiments, the map data and positioning data of the target vehicle, as well as the display device environment corresponding to the vehicle's map display, can also be obtained. The map status of the target vehicle can be determined through the map data and positioning data, thereby determining the map status and map display environment of the vehicle. This embodiment does not impose any restrictions on this.

[0039] S130: Determine a focus map according to preset focus map rules, map status, and map display environment.

[0040] Among them, the preset focus map rules can be understood as the pre-set focus map generation rules. The focus map can be understood as a map with a focus state, which can respond to the control terminal instructions on the vehicle's display terminal and display the corresponding map data. It should be noted that the number of focus maps determined is 1. For example, the vehicle's map software is installed with map A, map B and map C. If map B is currently in the focus state, the vehicle's display terminal displays the map data corresponding to map B and obeys the relevant instructions of the vehicle control terminal.

[0041] In this embodiment, the preset focus map rules can be multiple rules. Exemplarily, the preset focus map rules can be the corresponding rules when a specified map is currently initiating navigation, or when multiple maps are initiating navigation, first determine which state the map is in and which display environment the map display environment is in, and set the preset focus map rules based on the current map state and map display environment. Alternatively, when no map is in the navigation state, first determine whether there is a main screen foreground map, and then determine whether there is a split screen to determine the focus map. This embodiment does not limit the rules for the preset focus map.

[0042] In this embodiment, the change factors affecting the focus map may include the map state, the map display environment, and the preset focus map rules. The highest-priority factors of the map state and the map display environment can be determined according to the priority of the influencing factors corresponding to the preset focus map rules, so as to determine a focus map for navigation. In some embodiments, the priority of the map state can also be directly sorted through the current road map information, and the focus map in the current focus state can be determined by integrating the display rules of the vehicle display terminal.

[0043] S140. Navigate according to at least one map source and the focus map.

[0044] Among them, the map source includes the maps that may be used for vehicle map navigation. Exemplarily, the map source can be the Tencent Map software installed in the vehicle, or the Baidu Map software, the 360 Map software, etc.

[0045] In this embodiment, the map data of at least one map source can be received and compared with the determined focus map, and a judgment can be made based on the comparison results of each map data and the focus map. When the comparison result is the focus map, the focus data corresponding to the focus map is sent to the display terminal, so that the display terminal displays the focus map for navigation.

[0046] The above technical solution of the embodiment of the present invention starts map navigation through the preset trigger condition of the target vehicle, determines the map state and the map display environment of the target vehicle, determines the focus map according to the preset focus map rules, the map state and the map display environment, and navigates according to at least one map source and the focus map. In the embodiment of the present invention, by obtaining the map state, the map display environment, and the preset focus map rules, the display mode of the map on the display terminal is determined, and multiple map sources are matched with this map, so as to display the best-matched map on the display terminal according to the determined display mode, solve the map display problem in the case of multiple map sources and multiple display screens, improve the accuracy of map display data for accurate navigation, and at the same time enhance the user experience.

[0047] In one embodiment, the map navigation method further includes:

[0048] When the navigation start instruction input by the user is to initiate navigation for a specified map, use the specified map as the focus map for navigation.

[0049] In this embodiment, the navigation start instruction input by the user can be to initiate navigation for a specified map, or to directly input a navigation start instruction without specifying a particular map for initiating navigation. If the user specifies a map for initiating navigation, the specified map is directly used as the focus map for navigation. Exemplarily, if the navigation start instruction input by the user in a voice control manner is to specify Baidu Map for navigation, then Baidu Map is directly used as the current focus map for navigation.

[0050] In one embodiment, Figure 2 FIG. is a flowchart of another map navigation method provided by an embodiment of the present invention. Based on the above embodiments, this embodiment further refines starting map navigation according to a preset trigger condition of the target vehicle, determining the map state and map display environment of the target vehicle, determining the focus map according to a preset focus map rule, map state and map display environment, and performing navigation according to at least one map source and the focus map. As Figure 2 shown, the map navigation method in this embodiment can specifically include the following steps:

[0051] S210. Start map navigation according to a preset trigger condition of the target vehicle.

[0052] In this embodiment, S210 may include S201 and / or S202.

[0053] S201. Obtain a navigation start instruction input by the user.

[0054] In this embodiment, the user can send a corresponding control instruction to the control end by means of voice, text input, touch, etc. When receiving the control instruction input by the user, through semantic analysis corresponding to parsing the control instruction, a navigation start instruction is initiated according to the corresponding semantic analysis result. It should be noted that the result of this semantic analysis can be that the user directly specifies a certain map for navigation, or does not specify, and directly enters a navigation instruction. Exemplarily, the user can input a navigation start instruction for a specified map by voice, such as: specifying Map A for navigation; or directly input a corresponding navigation start instruction, and this navigation start instruction corresponds to at least one navigation map.

[0055] S202. Obtain a navigation start instruction generated by the control end according to the driving state of the target vehicle.

[0056] In this embodiment, when the target vehicle is in a driving state, corresponding map data can also be actively sent down by at least one map source to generate a corresponding navigation start instruction.

[0057] S220. Collect the map state and map display environment of the target vehicle.

[0058] In this embodiment, the navigation service system is used to collect the map status of the current target vehicle and the map display environment, so as to sort the map status and the map display environment accordingly. The map status in this embodiment includes at least one of the following: map navigation status, map cruise status, map foreground and background status; the map display environment includes at least one of the following: main screen of the in-vehicle display screen, secondary screen of the in-vehicle display screen, right screen of the split screen of the in-vehicle display screen, left screen of the split screen of the in-vehicle display screen, default setting.

[0059] S230. Obtain the map status and the map display environment.

[0060] In this embodiment, to obtain the map status and the map display environment, the map status can be obtained first and then the map display environment; or the map display environment can be obtained first and then the map status; or the map status and the map display environment can be obtained simultaneously. This embodiment does not limit the order of obtaining the map status and the map display environment.

[0061] S240. Obtain the priority of the influencing factors of the preset focus map rule.

[0062] Among them, the priority of the influencing factors can be understood as the relevant priority affecting the generation of the focus map. The priority of the influencing factors in this embodiment can include the priority of the map status and the priority of the map display environment.

[0063] In this embodiment, the priority of the map status and the priority of the map display environment corresponding to the preset focus map rule can be obtained. It should be noted that since there are multiple preset focus map rules, each preset focus rule corresponds to a corresponding priority of the map status and a priority of the map display environment. The priority of the map status in this embodiment can sort the map status according to a certain order of priority. Of course, the priority of the map display environment can also sort the map display environment according to a certain order of priority. Exemplarily, the size order of the priority of the map status is: the map is in the foreground navigation state > the map is in the background navigation state; the size order of the priority of the display environment is the main screen of the in-vehicle display screen > the secondary screen of the in-vehicle display screen. Of course, when the main screen and the secondary screen of the in-vehicle display screen are split screens, the right screen of the split screen of the in-vehicle display screen is greater than the left screen of the split screen of the in-vehicle display screen.

[0064] In one embodiment, the priority of the influencing factors includes at least one of the following:

[0065] The priority of the map status and the priority of the map display environment;

[0066] Among them, when the target vehicle currently has a map in the navigation state, the priority of the map status decreases in the order of foreground navigation state, background navigation state, and the most recent navigation;

[0067] When the target vehicle is in the navigation state without a map, the priority of the map state decreases in the order of the map foreground state, the map cruise state, and the default map state;

[0068] The priority of the map display environment decreases in the order of the main screen of the in-vehicle display screen and the secondary screen of the in-vehicle display screen; and / or, it decreases in the order of the right screen of the split screen of the in-vehicle display screen and the left screen of the split screen of the in-vehicle display screen.

[0069] In this embodiment, the influencing factor priority includes the map state priority and the map display environment priority. Of course, the map state priority can be divided into different map state priorities according to whether the vehicle currently has a map in the navigation state. When the target vehicle currently has a map in the navigation state, the map state priority can decrease in the order of the foreground navigation state, the background navigation state, and the most recent navigation. When the target vehicle currently has no map in the navigation state, the map state priority can decrease in the order of the map foreground state, the map cruise state, and the default map state. In this embodiment, the priority of the map display environment can decrease in the order of the main screen of the in-vehicle display screen and the secondary screen of the in-vehicle display screen; and / or, it can decrease in the order of the right screen of the split screen of the in-vehicle display screen and the left screen of the split screen of the in-vehicle display screen.

[0070] It should be noted that the map state priority and the map display environment priority can be set accordingly according to user preferences, user habits, user needs, user experience, etc.

[0071] S250. Determine the highest priority factor of the map state and the map display environment according to the influencing factor priority.

[0072] Among them, the highest priority factor refers to the priority factor that can generate the focused map.

[0073] In this embodiment, the highest priority factor can be obtained from the map state priority and the map display environment priority. Specifically, the priority sorting corresponding to the map state priority and the map display environment priority can be carried out to determine the highest priority factor of the map state and the map display environment. Exemplarily, when the map state is the map foreground navigation state and the map display environment includes the main screen foreground and the right screen of the split screen of the in-vehicle display screen, and when there are at least two maps in the navigation state, there is a map in the main screen foreground navigation state of the in-vehicle display screen, and there is a map in the right screen foreground navigation state of the split screen of the in-vehicle display screen, the map in the right screen foreground navigation state of the split screen of the in-vehicle display screen is the highest priority factor; another example is that when there is no map in the navigation state, there is no foreground map on the main screen and the secondary screen, and there is a map in the cruise state, then the cruise state map is the highest priority factor.

[0074] S260. Determine a focus map for navigation according to the highest-priority factor.

[0075] In this embodiment, a focus map for navigation can be determined according to the highest-priority factor corresponding to the map state and the map display environment. It should be noted that since the map state priority can be divided into two cases where the current target vehicle is in the navigation state and the current target vehicle is not in the navigation state, the following will give two cases to determine a focus map for navigation according to the highest-priority factor corresponding to the map state and the map display environment.

[0076] In this embodiment, when there is a current map in the navigation state, it is judged whether there are at least two maps in the navigation state. If there are not at least two maps in the navigation state, the current navigation state map initiates navigation, and the current navigation state map is the highest-priority factor, and the current navigation state map is taken as the focus map; if there are at least two maps in the navigation state, it is judged whether there is a main screen foreground navigation state map on the in-vehicle display screen. If there is a main screen foreground navigation state map on the in-vehicle display screen, it is then sequentially judged whether there is a right split-screen foreground navigation state map and a left split-screen foreground navigation state map on the in-vehicle display screen. If there is a right split-screen foreground navigation state map on the in-vehicle display screen, the highest-priority factor is the right split-screen foreground navigation state map on the in-vehicle display screen, and the right split-screen foreground navigation state map on the in-vehicle display screen is taken as the focus map; if there is no right split-screen foreground navigation state map on the in-vehicle display screen, when there is a left split-screen foreground navigation state map on the in-vehicle display screen, the highest-priority factor is the left split-screen foreground navigation state map on the in-vehicle display screen, and the left split-screen foreground navigation state map on the in-vehicle display screen is taken as the focus map. If neither the right split-screen foreground navigation state map nor the left split-screen foreground navigation state map on the in-vehicle display screen exists, the main screen foreground navigation state map on the in-vehicle display screen is the highest-priority factor, and the main screen foreground navigation state map on the in-vehicle display screen is taken as the focus map.

[0077] In this embodiment, when the current map is not in the navigation state, it is determined whether there is a foreground map on the main screen of the in-vehicle display. If there is a foreground map on the main screen of the in-vehicle display, it is further determined whether there are foreground maps on the right split screen and the left split screen of the in-vehicle display. If there is a foreground map on the right split screen of the in-vehicle display, the foreground map on the right split screen of the in-vehicle display is the highest-priority factor, and the foreground map on the right split screen of the in-vehicle display is used as the focus map. If there is no foreground map on the right split screen of the in-vehicle display, and there is a foreground map on the left split screen of the in-vehicle display, the foreground map on the left split screen of the in-vehicle display is the highest-priority factor, and the foreground map on the left split screen of the in-vehicle display is used as the focus map. If neither the foreground map on the right split screen nor the foreground map on the left split screen of the in-vehicle display exists, the foreground map on the main screen of the in-vehicle display is the highest-priority factor, and the foreground map on the main screen of the in-vehicle display is used as the focus map; if there is no foreground map on the main screen of the in-vehicle display, it is necessary to determine whether there is a foreground map on the secondary screen of the in-vehicle display. If there is a foreground map on the secondary screen of the in-vehicle display, it is sequentially determined whether there are foreground maps on the right split screen and the left split screen of the in-vehicle display. If there is a foreground map on the right split screen of the in-vehicle display, the foreground map on the right split screen of the in-vehicle display is the highest-priority factor, and the foreground map on the right split screen of the in-vehicle display is used as the focus map. If there is no foreground map on the right split screen of the in-vehicle display, and there is a foreground map on the left split screen of the in-vehicle display, the foreground map on the left split screen state map of the in-vehicle display is used as the focus map; if neither the foreground map on the right split screen nor the foreground map on the left split screen of the in-vehicle display exists, the foreground map on the secondary screen of the in-vehicle display is the highest-priority factor, and the foreground map on the secondary screen of the in-vehicle display is used as the focus map. If there is no foreground map on the secondary screen of the in-vehicle display, it is determined whether there is a map in the cruise state. If so, the cruise state map initiates navigation. At this time, the cruise state map is the highest-priority map, and the cruise state map is used as the focus map; if not, the default navigation map is used as the focus map.

[0078] S270. Receive map data from at least one map source.

[0079] Among them, the map data may include information on route planning (Turn by turn, TBT), road conditions, arrival time and other data.

[0080] In this embodiment, each map source corresponds to corresponding map data such as TBT, road conditions, arrival time, etc. Exemplarily, the current map sources are Figure 1 , Figure 2 and Figure 3 . The map data corresponding to Figure 1 , Figure 2 and Figure 3 are respectively sent to the navigation system service.

[0081] S280. Compare the map data of each location with the focus map.

[0082] In this embodiment, after obtaining the focus map, it is necessary to compare the focus map with the map data corresponding to each of the at least one received map source, so as to determine whether to send the map data corresponding to the focus map according to the comparison result.

[0083] Exemplarily, the existing Figure 1 and Figure 2 , the focus map is Figure 1 , the navigation system will save this focus map ( Figure 1 ), when the map data corresponding to the focus map ( Figure 1 ) and Figure 2 are sent to the display end for display respectively, when matching the focus map ( Figure 1 ), the map data of the focus map ( Figure 1 ) is sent to the display end for corresponding display, while the map data corresponding to Figure 2 is not sent.

[0084] S290. In the case where the comparison result is the focus map, send the focus data corresponding to the focus map to the display end for display as the focus map.

[0085] Among them, the focus data can be understood as the map data corresponding to the focus map, and can include data such as TBT, road conditions, arrival time, etc.

[0086] In this embodiment, compare the focus map with the map data of the at least one received map source. In the case where the comparison result is the focus map, send the focus data corresponding to the focus map to the display end for display as the focus map.

[0087] S2100. In the case where the comparison result is not the focus map, do not send the focus data.

[0088] In this embodiment, compare the focus map with the map data of the at least one received map source. In the case where the comparison result is not the focus map, do not send the focus data.

[0089] In the above technical solution of this embodiment, by obtaining the priority of influencing factors of a preset focus map rule, determining the highest-priority factor of the map state and the map display environment according to the priority of influencing factors, and determining a map for navigation according to the highest-priority factor, it is possible to further achieve an orderly switching and use of the map by the control end on a multi-map vehicle-mounted device; by comparing the map data of at least one map source with the focus map, when the comparison result is the focus map, the focus data corresponding to the focus map is sent to the display end for display, and when the comparison result is not the focus map, the focus data is not sent down, so that the display end can accurately display the map data corresponding to the focus map for accurate navigation.

[0090] In one embodiment, for better understanding of the map navigation method, Figure 3 It is a schematic diagram of the interaction structure among the control end, the map end, the display end, etc. in a map navigation method provided by an embodiment of the present invention. The main screen foreground navigation state map in this embodiment represents the vehicle-mounted display main screen foreground navigation state map in the above embodiment, the secondary screen foreground navigation state map represents the vehicle-mounted display secondary screen foreground navigation state map in the above embodiment, the split-screen right screen foreground navigation state map represents the vehicle-mounted display split-screen right screen foreground navigation state map in the above embodiment, and the split-screen left screen foreground navigation state map represents the vehicle-mounted display split-screen left screen foreground navigation state map in the above embodiment.

[0091] As Figure 3 shown, the structure of the map navigation method includes: a control end 310, a navigation service system 320, a map end 33 and a display end 340. The interaction among at least one map source in the navigation service system 320, the map end 330, the control end 310 and the display end 340 will be described in detail. The map end 330 (Map A, Map B, Map C) sends down data (TBT, road conditions, arrival time, etc.), and the navigation service system 320 judges the states of each map and notifies the most suitable map data to the display end 340 (head-up display, vehicle instrument, etc.) for display according to the preset priority. Instructions can be sent from the control end 310 (such as voice, steering wheel control, etc.) to the navigation service system 320, and according to the judgment of the states of each map, the most suitable map application is sent to the display end 340 for display.

[0092] In one embodiment, Figure 4The flowchart shows the process of a control terminal issuing a control instruction to determine a focus map according to an embodiment of the present invention. In this embodiment, an example is given where the control terminal issues a control instruction to interact with a navigation service system and a map terminal to obtain a focus map.
