Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of map navigation, and particularly relates to a navigation prompting method, device, equipment and program product in a cruising state. BACKGROUND

[0002] During vehicle driving, a navigation client can perform driving prompting on a vehicle in a cruising state. The driving prompting in the cruising state can be understood as that, in the case that a user does not set a destination, the navigation client displays a current position of the vehicle, and prompts traffic information on a road to be walked in front of the vehicle.

[0003] At present, traffic information prompting in the cruising state is mainly processed in the form of points. Taking electronic eye broadcasting as an example, a corresponding broadcasting event is to set a broadcasting point position at a certain distance from an actual position of the electronic eye. When the navigation client judges that a straight-line distance between the current position of the vehicle and the broadcasting point position is less than a certain set value, the broadcasting event of the electronic eye is triggered.

[0004] However, due to the influence of various factors such as positioning error and electronic eye position interference on similar roads, the above processing manner will make the broadcasting probability and the broadcasting accuracy of the traffic information on each point in the cruising state both relatively low.

[0054] Embodiments of the present disclosure will be described in more detail by referring to the drawings. Although certain embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms, and should not be construed as being limited to the embodiments set forth herein, but rather, these embodiments are provided so as to more completely and thoroughly understand the present disclosure. It is understood that the drawings and embodiments of the present disclosure are for exemplary purposes only, and are not intended to limit the scope of protection of the present disclosure.

[0055] It is understood that each step recited in the method embodiments of the present disclosure can be executed in different orders, and / or in parallel. In addition, the method embodiments can include additional steps and / or omit the execution of the steps shown. The scope of the present disclosure is not limited in this respect.

[0056] The term “comprising” and variations thereof as used herein are open-ended, that is “including but not limited to”. The term “based on” is “based, at least in part, on”. The term “one embodiment” means “at least one embodiment”; the term “another embodiment” means “at least one additional embodiment”; the term “some embodiments” means “at least some embodiments”. Related definitions are given below in the description of the terms.

[0057] It should be noted that the terms "first", "second", and the like in the present disclosure are merely used to distinguish different devices, modules or units, and do not imply the sequence or interdependence of the functions performed by these devices, modules or units.

[0058] It should be noted that the terms "one", "multiple" in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that "one" or "multiple" should be understood as "one or more" unless the context clearly indicates otherwise.

[0059] The current navigation client can provide traffic information prompt function for vehicles in cruise state. For example, when the navigation client is set in cruise state, the navigation client can broadcast the traffic information such as electronic eye and traffic signal on the road ahead of the vehicle.

[0060] In the related art, the navigation client mainly calculates the straight line distance between the prompt point position corresponding to a certain traffic information and the current position of the vehicle, and compares whether the straight line distance is less than a certain set value, to determine whether to trigger the prompt processing of the traffic information corresponding to the prompt point position. For example, for a certain electronic eye in the direction of vehicle travel, a broadcast point position can be set at a certain distance from the electronic eye, and an electronic eye broadcast event is set for the broadcast point position. When the navigation client determines that the straight line distance between the current position of the vehicle and the broadcast point position is less than a certain set value (such as 30 meters), it is considered that the vehicle has reached the broadcast point position, and the electronic eye broadcast event is triggered, such as broadcasting "the speed limit XX shooting electronic eye ahead".

[0061] However, the accuracy and completeness of the above-mentioned cruise prompt trigger method using position point matching depend on the accuracy of the current position of the vehicle and the prompt point position. If the positioning error of the current position is large, or the current position jumps due to poor positioning stability, the navigation client will calculate the wrong straight line distance, and then give the wrong prompt trigger result, resulting in missed traffic information or repeated prompt. If the prompt point positions corresponding to different traffic information are close to each other, the prompt point position irrelevant to the road in the direction of vehicle travel may be matched, and then the irrelevant traffic information is also prompted, which interferes with the vehicle travel. Therefore, the above-mentioned cruise prompt trigger method using position point matching will cause the traffic information prompt penetration rate and the prompt accuracy to be low during the cruise.

[0062] The above prompt penetration rate can be understood as the ratio of the actual prompt events of the traffic information prompted to the user to the actual prompt events of the traffic information produced. For example, during a cruise driving, a total of 100 traffic information prompt events are produced, but only 80 of them are actually triggered for prompting, and thus the prompt penetration rate of the cruise driving is 80%.

[0063] Based on the above, the navigation prompting method in the cruise state is provided to, in the scenario that the navigation client is set in the cruise state, make the navigation client obtain the current driving route of the vehicle in the travel direction and the navigation event information on the current driving route, which at least contains the line type prompt event, and prompt the navigation event information matched with the current position along the current driving route, so as to upgrade the cruise prompting form without route in the related art to the cruise prompting form with route assistance (without displaying the route), thereby shielding the prompt events irrelevant to the current driving route, improving the positioning matching accuracy of the prompt events through the setting of the linear prompt interval, improving the information content of the prompt events through the production of the line type prompt event, and further improving the penetration rate, accuracy and expandability of the traffic information prompted in the cruise state.

[0064] In an implementation manner, the process of obtaining the current driving route and the navigation event information can be set in the navigation server, and the process of prompting the traffic information in the cruise state can be set in the navigation client. In this way, the online map data in the navigation server can be used to obtain the traffic information with higher real-time performance and higher accuracy, thereby improving the dynamic degree and accuracy of the cruise prompting. The online map data in the present application refers to the map data that can be connected to the network, which can be high-precision map / high-definition map / three-dimensional map and the like with higher accuracy, or can be standard-precision map / navigation map / two-dimensional map and the like with relatively lower accuracy.

[0065] In the implementation manner, the information interaction process between the navigation client and the navigation server can refer to Figure 1 . As shown in Figure 1 , the navigation prompting method in the cruise state specifically includes:

[0066] S110, the navigation client obtains the current position of the vehicle.

[0067] S120, the navigation client sends a navigation event obtaining request to the navigation server based on the current position.

[0068] S130, the navigation server responds to the navigation event obtaining request, predicts the driving route of the vehicle at the future time based on the current position, and generates the current driving route.

[0069] S140, the navigation server generates navigation event information based on the current driving route and online map data. The navigation event information includes at least one line type prompt event, and the line type prompt event is a prompt event including a linear prompt interval along the driving route.

[0070] S150, the navigation server sends the current driving route and the navigation event information to the navigation client.

[0071] S160, the navigation client prompts the current prompt event in the navigation event information triggered by the current position when it is determined that the current position matches the current driving route.

[0072] Figure 2 A flowchart of a navigation prompting method in a cruise state applied to a navigation client is provided in the embodiments of the present disclosure. The navigation prompting method in the cruise state applied to the navigation client can be executed by a navigation prompting device configured in the cruise state of the navigation client. The device can be implemented by software and / or hardware, and can be integrated on an electronic device installed with the navigation client. The electronic device can be, for example, a smart mobile device such as a smartphone, a tablet computer, a palm computer, a notebook computer, a smart wearable device, etc. which has no hardware connection relationship with a vehicle; or the electronic device can be a vehicle-mounted device such as a car machine, etc. which has a hardware connection relationship with the vehicle.

[0073] As shown in Figure 2 The navigation prompting method in the cruise state applied to the navigation client provided in the embodiments of the present disclosure can include the following steps.

[0074] S210, obtaining the current position of the vehicle.

[0075] Specifically, the navigation client is installed in the electronic device, so it can obtain the positioning position of the vehicle at the current time through the electronic device as the current position of the vehicle.

[0076] If the electronic device is a vehicle-mounted device, the navigation client can obtain the current position obtained by the positioning device carried by the vehicle through internal communication of the vehicle.

[0077] If the electronic device is a smart mobile terminal, considering that the smart mobile terminal is placed in the vehicle during the driving of the vehicle, the instantaneous positioning position of the smart mobile terminal is consistent with the instantaneous positioning position of the vehicle, so the current position can be obtained through the positioning device built-in the smart mobile terminal. Alternatively, the navigation client can obtain the current position obtained by the positioning device carried by the vehicle through wireless communication between the smart mobile terminal and the vehicle.

[0078] S220, sending a navigation event acquisition request to the navigation server based on the current position.

[0079] The navigation event acquisition request is a remote request sent to the navigation server for acquiring the navigation event information. The navigation event information refers to information of an event (referred to as a prompt event) that can be triggered to prompt, which is generated by traffic information that can prompt the vehicle to travel in the cruising state. For example, the navigation event information can include an actual geographic location (referred to as an event anchor point) of the traffic information, prompt content (referred to as event content) of the traffic information, a trigger condition of the prompt event, a prompt manner, and the like.

[0080] Specifically, the navigation client generates a navigation event acquisition request by using the current position according to a communication protocol between the navigation client and the navigation server, and sends the navigation event acquisition request to the navigation server to trigger the navigation server to perform a related operation of generating the navigation event information.

[0081] S230, receiving the current travel route and the navigation event information fed back by the navigation server in response to the navigation event acquisition request.

[0082] Specifically, after receiving the navigation event acquisition request, the navigation server can obtain the current position of the vehicle by parsing the navigation event acquisition request. Then, the navigation server infers a route that the vehicle is most likely to travel in a future period of time based on the current position, the travel information of the vehicle at a historical time point before the current time point, and / or the road information in the online map data, to obtain the current travel route. For example, the travel information of the historical time point can be any one of a historical position, a historical trajectory, and a preset location. The current travel route can be obtained by fitting the current position and the historical trajectory corresponding to the current position, or the current travel route can be generated by route planning of the current position and at least two preset locations, or the current travel route can be generated by filtering the road information in the online map data based on the current position and at least one historical position corresponding to the current position. The generation process of the current travel route can be referred to the detailed description of subsequent embodiments.

[0083] Then, the navigation server obtains traffic information for navigation that is adapted to the current travel route by using a related technology of route navigation, and generates the navigation event information by using the traffic information. Finally, the navigation server sends the current travel route and the navigation event information obtained as feedback information to the navigation client according to the communication protocol. In this way, the navigation client receives the current travel route and the navigation event information fed back by the navigation server.

[0084] It is worth noting that because the navigation event information is generated based on the current driving route using the related technology of route navigation, the navigation event information can not only include the information of the point type prompt event (referred to as a point type prompt event) of the prompt point position containing traffic information, but also include the information of the line type prompt event (referred to as a line type prompt event) related to the current driving route. The line type prompt event can be a prompt event containing a linear prompt interval. The linear prompt interval can be understood as a range on the current driving route in which traffic information can be prompted.

[0085] Taking the prompt event of the electronic eye as an example. For the point type prompt event, refer to Figure 3 The broadcast point position 320 is arranged at a certain distance from the electronic eye 310 on the road in the shooting direction of the electronic eye 310, and a broadcast trigger range 330 of the electronic eye 310 is arranged with the broadcast point position 320 as the center and a radius of, for example, 30 meters. In this way, the point type prompt event can at least include the event anchor point of the electronic eye 310, the broadcast point position 320, and the broadcast trigger range 330. The point type prompt event needs to be broadcast to the electronic eye 310 when the current position of the vehicle is in the broadcast trigger range 330.

[0086] Similarly, taking the prompt event of the electronic eye as an example. For the line type prompt event, refer to Figure 4 The electronic eye 410 is on the current driving route 420, which is composed of 4 roads carrying driving direction arrows. In order to improve the prompt success rate and accuracy of the electronic eye, a prompt lower limit position 430 and a prompt upper limit position 440 can be arranged in the current driving route 420. The prompt lower limit position 430 and the prompt upper limit position 440 can constitute a linear prompt interval of the electronic eye 410 on the current driving route 420, representing that the electronic eye broadcast can be triggered in the linear prompt interval. In this way, the line type prompt event can at least include the event anchor point of the electronic eye 410, the prompt lower limit position 430 and the prompt upper limit position 440 on the current driving route 420.

[0087] The prompt lower limit position is a position point on the current driving route in the direction close to the vehicle / away from the electronic eye, and the prompt upper limit position is a position point on the current driving route in the direction away from the vehicle / close to the electronic eye, both of which can be set according to the business needs or user needs of traffic information prompt in the cruise state. For example, the broadcast needs of the electronic eye are to broadcast within a range of 200 meters to 500 meters away from the electronic eye, then the prompt lower limit position 430 can be set as a position along the current driving route 420 500 meters away from the electronic eye 410, and the prompt upper limit position 440 can be set as a position along the current driving route 420 200 meters away from the electronic eye 410.

[0088] Through the above Figure 3 and Figure 4 A comparison shows that line-type alert events contain more information than point-type alert events. Furthermore, by constructing linear alert intervals, they can expand the scope of traffic information alerts, increasing the probability of the corresponding alert event being captured, thereby improving the probability and accuracy of the alert being displayed. In addition, because line-type alert events are accompanied by the current driving route, they can expand the content of more traffic information related to the current driving route, enhancing the scalability of cruise control alerts. For example, line-type alert events can also include the real-time distance between the vehicle's current position and the electronic eye on the current driving route.

[0089] In some embodiments, line-type prompt events include traffic facility prompt events and / or traffic status prompt events. If the traffic facility includes electronic surveillance cameras and / or traffic lights, then the traffic facility prompt event can provide notifications about the electronic surveillance cameras and / or traffic lights. If the traffic status includes at least one of road congestion level, traffic accidents, road repairs, and road control, then the traffic status prompt event can provide notifications about whether the road ahead is congested, the degree of congestion, the length of the congestion, whether a traffic accident has occurred, the actual situation of the traffic accident, and whether the road ahead is under road repair or road control. This enhances the richness and dynamism of navigation prompts during cruise control.

[0090] S240. If it is determined that the current location matches the current driving route, then the current prompt event triggered by the current location in the navigation event information is displayed.

[0091] Among them, the current prompt event is a prompt event that is selected from the prompt events included in the navigation event information and whose current location is within its prompt range.

[0092] Specifically, based on the foregoing explanation, navigation event information is a prompt event indicating the current driving route. Therefore, the navigation client first matches the current location with the current driving route according to route matching rules to determine whether the vehicle is traveling along the current route. These route matching rules could be, for example: if multiple routes exist simultaneously, the navigation client matches the vehicle's location to the route with the shortest distance between the current location and each route; if there is only one route, and the distance between the current location and that route is not too large, then the vehicle's location is matched to that route.

[0093] Compared with the matching of two position points, the route-priority matching can reduce the influence of the positioning error to a greater extent. For example, when two position points are matched, a positioning error of 5 meters in the current position can also cause the matching of the two position points to fail. However, when the route-priority matching is performed, the current position can be positioned on the route even if the positioning error of the current position is 10 meters. In this way, the matching accuracy of the current position and the navigation event information can be improved to a certain extent, and the accuracy of the traffic information in the cruise state can be improved.

[0094] If the navigation client determines that the current position matches the current driving route, it indicates that the vehicle is driving along the current driving route. At this time, the current prompt event that can be triggered by the current position can be determined from each prompt event included in the navigation event information. For example, each prompt event can be filtered to determine the current prompt event according to the current position and the promptable range of the prompt event. For another example, each prompt event can be sorted according to the event anchor point of the prompt event along the driving direction of the current driving route, and the closest prompt event to the current position can be selected from the sorted prompt events as the current prompt event.

[0095] Then, the navigation client prompts the current prompt event according to a preset prompt mode. The preset prompt mode is a prompt mode of the traffic information that is preset, which can be information carried in the navigation event information or information set by the user in the navigation client. The preset prompt mode can be, for example, a voice broadcast mode and / or a graphic display mode.

[0096] It is worth noting that in the above prompt process, the current driving route is auxiliary information for the positioning matching of the current position and the taking effect of the navigation event information, and does not need to be displayed on the display screen of the electronic device.

[0097] In some embodiments, after S230, the navigation prompting method applied to the navigation client in the cruise state further includes: if it is determined that the current position does not match the current driving route, proceeding to S210.

[0098] Specifically, if the navigation client determines that the current position does not match the current driving route, it indicates that the vehicle is not driving along the current driving route, and the actual driving trajectory has deviated from the current driving route, such as the driving position and / or driving direction of the vehicle deviating from the current driving route. Therefore, the navigation prompting in the cruise state cannot continue according to the current driving route and the corresponding navigation event information. At this time, the navigation client can re-trigger the navigation prompting processing flow of S210-S240 to obtain a new current position, request the navigation server to obtain a new current driving route and new navigation event information with the new current position, and perform navigation prompting with the new current driving route and the new navigation event information.

[0099] Take the point type prompt event and the line type prompt event as examples, the effect of the navigation prompt method in the current driving route assisted cruise state is briefly described. Figure 3 Figure 4 For the electronic eye broadcast event of the point type as shown in FIG. 4, if the positioning error of the current position is large, the navigation client is still likely to determine that the current position of the vehicle does not reach the broadcast trigger range 330 when the vehicle has traveled into the broadcast trigger range 330, resulting in missing the electronic eye broadcast event. For the electronic eye broadcast event of the line type as shown in FIG. 5, under the condition that the vehicle positioning matches the current driving route 420, if the vehicle travels to the first position 450, the navigation client can determine that the current position is not in the linear prompt interval, and at this time, no broadcast is needed; if the vehicle travels to the second position 460, the navigation client can determine that the current position is in the linear prompt interval, and at this time, the electronic eye broadcast is triggered. Even if there is a large positioning error, the probability of missing the electronic eye broadcast event can be reduced as much as possible because the range of the linear prompt interval is large, thereby greatly improving the penetration rate, prompt accuracy and integrity of the prompt event.

[0100] For the electronic eye broadcast event of the point type as shown in FIG. 4, if the positioning error of the current position is large, the navigation client is still likely to determine that the current position of the vehicle does not reach the broadcast trigger range 330 when the vehicle has traveled into the broadcast trigger range 330, resulting in missing the electronic eye broadcast event. For the electronic eye broadcast event of the line type as shown in FIG. 5, under the condition that the vehicle positioning matches the current driving route 420, if the vehicle travels to the first position 450, the navigation client can determine that the current position is not in the linear prompt interval, and at this time, no broadcast is needed; if the vehicle travels to the second position 460, the navigation client can determine that the current position is in the linear prompt interval, and at this time, the electronic eye broadcast is triggered. Even if there is a large positioning error, the probability of missing the electronic eye broadcast event can be reduced as much as possible because the range of the linear prompt interval is large, thereby greatly improving the penetration rate, prompt accuracy and integrity of the prompt event. Figure 3 Figure 4 For the electronic eye broadcast event of the point type as shown in FIG. 4, if the positioning error of the current position is large, the navigation client is still likely to determine that the current position of the vehicle does not reach the broadcast trigger range 330 when the vehicle has traveled into the broadcast trigger range 330, resulting in missing the electronic eye broadcast event. For the electronic eye broadcast event of the line type as shown in FIG. 5, under the condition that the vehicle positioning matches the current driving route 420, if the vehicle travels to the first position 450, the navigation client can determine that the current position is not in the linear prompt interval, and at this time, no broadcast is needed; if the vehicle travels to the second position 460, the navigation client can determine that the current position is in the linear prompt interval, and at this time, the electronic eye broadcast is triggered. Even if there is a large positioning error, the probability of missing the electronic eye broadcast event can be reduced as much as possible because the range of the linear prompt interval is large, thereby greatly improving the penetration rate, prompt accuracy and integrity of the prompt event.

[0101] In some embodiments, for the line type prompt event included in the navigation event information, S240 can be specifically implemented as: if it is determined that the current position matches the current driving route, matching the current position and the linear prompt interval, and determining the line type prompt event corresponding to the linear prompt interval that matches successfully as the current prompt event; and prompting the current prompt event.

[0102] Specifically, after the navigation client matches the current position positioning to the current driving route, the navigation client can match the current position with the linear prompt interval in each line type prompt event.

[0103] If all the matching fails, it means that there is no line type prompt event that can be triggered at the current position, at this time, it can be to continue to obtain a new current position and repeatedly execute S240, or it can be to match the remaining prompt events such as the point type prompt event in the navigation event information according to the current position. If there is a matching successful point type prompt event, it is prompted; if there is also no matching successful point type prompt event, it can continue to obtain a new current position and repeatedly execute S240.

[0104] If only one matches successfully, the line type prompt event corresponding to the linear prompt interval that matches successfully is taken as the current prompt event, and it is prompted.

[0105] ​​If multiple line type prompt events are matched successfully, one unprompted line type prompt event can be randomly selected from the multiple matched line type prompt events as the current prompt event, or the line type prompt event closest to the current position can be selected from the multiple matched line type prompt events as the current prompt event according to the event anchor point of the line type prompt event. Then, the navigation client prompts the current prompt event in the cruise state during vehicle driving.

[0106] In this embodiment, the current position is matched with the linear prompt interval, the vehicle is prompted in the promptable range of the line type prompt event, the rationality of the prompt timing of the corresponding traffic information is improved, and the problem of early prompt interfering with the driver or the problem of late prompt causing ineffective prompt is avoided.

[0107] In some embodiments, when the preset prompt mode is the voice broadcast mode, the above-mentioned "prompting the current prompt event" can include: broadcasting the event content of the current prompt event and the current distance between the current position and the event anchor point of the current prompt event in the linear prompt interval of the current prompt event.

[0108] Specifically, when the current position is in the linear prompt interval of the current prompt event, the navigation client can broadcast the event content of the current prompt event according to the pre-set broadcast frequency (i.e., the preset frequency) and the broadcast script. The preset frequency can be a fixed frequency defined by driving distance, for example, the vehicle triggers the broadcast once every 50 meters of driving distance (i.e., the current position moves 50 meters in the linear prompt interval). It can also be a dynamic frequency defined by the distance between the current position and the event anchor point, for example, the farther the distance between the current position and the event anchor point, the lower the preset frequency, and the closer the distance between the current position and the event anchor point, the higher the preset frequency.

[0109] At the same time, with the aid of the current driving route, the navigation client can obtain the route information from the current position to the event anchor point of the current prompt event, so it can calculate the current distance between the current position and the event anchor point of the current prompt event in real time. Then, the current distance is broadcasted according to the preset frequency and the broadcast script. For example, for electronic eye broadcast, the navigation client can broadcast "xx meters ahead of the speed limit XX speed measurement photo electronic eye".

[0110] In an example, the above-mentioned "broadcasting the event content of the current prompt event and the current distance between the current position and the event anchor point of the current prompt event in the linear prompt interval of the current prompt event" includes: if the current position is between the prompt lower limit position and the prompt upper limit position of the linear prompt interval, the event content of the current prompt event and the current distance are broadcasted.

[0111] In this example, the navigation client determines whether the current position is in the linear prompt interval by comparing the current position with the lower limit position and the upper limit position of the prompt. If the current position has exceeded the lower limit position and has not reached the upper limit position along the travel direction of the current travel route, the above event content and the real-time current distance can be announced.

[0112] In another example, the above "announcing the event content of the current prompt event and the current distance between the current position and the event anchor point of the current prompt event in the linear prompt interval of the current prompt event" includes: determining a broadcast start road identifier and a broadcast end road identifier from the current travel route based on the current position and the upper limit position of the linear prompt interval; and announcing the event content of the current prompt event and the current distance in the road range of the broadcast start road identifier and the broadcast end road identifier at a preset frequency.

[0113] In this example, the current travel route at least contains road identifiers ID of the roads covered therein. Therefore, when the current position is in the linear prompt interval, the navigation client can locate the current position and the upper limit position of the linear prompt interval to specific roads in the current travel route, respectively, to obtain the road identifier corresponding to the current position as the broadcast start road identifier and the road identifier corresponding to the upper limit position as the broadcast end road identifier. Then, the navigation client can announce the above event content and the real-time current distance in the road range between the broadcast start road identifier and the broadcast end road identifier at a preset frequency and broadcast speech. In this way, the specific annunciable range is determined by locating the road identifier, which does not need to compare the current position with the lower limit position and the upper limit position in real time, on the one hand, can reduce the consumption of computing resources of the electronic device, thereby further improving the navigation prompt efficiency and real-time performance, on the other hand, can use the positioning matching of the current position and the road to reduce the influence of positioning error, thereby further improving the accuracy of navigation prompt.

[0114] In other embodiments, when the preset prompt mode is a graphic display mode, the above "prompting the current prompt event" can include: displaying the event content and the current distance of the current prompt event in the current display page.

[0115] Specifically, based on the auxiliary role of the current travel route, the navigation client can calculate the current distance between the current position and the event anchor point of the current prompt event in real time. Then, in the cruise state, the navigation client can display the event content of the current prompt event and the real-time current distance in the current display page displayed by the screen of the electronic device, so that the driver can view the event content and the current distance at any time, improve the convenience of the driver to learn the current prompt event, and further improve the success rate of the prompt of the current prompt event.

[0116] In yet some embodiments, when the preset prompt mode is the voice broadcast mode and the text display mode, the above-mentioned "prompting the current prompt event" can include: in the linear prompt interval of the current prompt event, broadcasting the event content of the current prompt event and the current distance between the current position and the event anchor point of the current prompt event; and displaying the event content of the current prompt event and the current distance in the current display page.

[0117] Specifically, in this embodiment, the navigation client can display the event content of the current prompt event and the real-time current distance in the current display page displayed by the screen of the electronic device. Meanwhile, the navigation client can perform voice broadcast reminding of the event content of the current prompt event and the real-time current distance according to the preset frequency and broadcast script. In this way, the exposure rate of the current prompt event can be further increased, so as to further improve the prompt success rate of the current prompt event.

[0118] In some embodiments, the navigation event information further includes at least one point type prompt event. The point type prompt event can be a traffic facility prompt event and / or a traffic state prompt event. Based on the above description, the point type prompt event at least includes a point-based prompt range. The point-based prompt range refers to a prompt trigger range formed with the prompt point position of the point type prompt event as the center. See Figure 3 For the example of electronic eye broadcast, the point-based prompt range can be the broadcast trigger range 330.

[0119] On the basis of this embodiment, S240 can be specifically implemented as: if it is determined that the current position matches the current driving route, matching the current position and the point-based prompt range, and determining the point type prompt event corresponding to the matched point-based prompt range as the current prompt event; prompting the current prompt event.

[0120] Specifically, the navigation client can match the current position and each point-based prompt range in the case that the current position positioning matches the current driving route. If the current position is in a certain point-based prompt range, the point type prompt event corresponding to the point-based prompt range is determined as the current prompt event, and it is prompted. The prompt mode and implementation process of the point type prompt event can refer to the description of the above-mentioned line type prompt event embodiment.

[0121] Figure 5A flowchart of a navigation prompting method in a cruising state applied to a navigation server is provided in the embodiments of the present disclosure. The navigation prompting method in the cruising state applied to the navigation server can be executed by a navigation prompting device in the cruising state configured in the navigation server. The device can be implemented by software and / or hardware, and can be integrated in an electronic device where the navigation server for providing navigation service is located. The electronic device can be, for example, a desktop computer, a server, etc.

[0122] Based on the above description of the embodiments, the navigation prompting function in the cruising state is realized by information interaction between the navigation client and the navigation server. Therefore, the same or similar terms and steps in the embodiments can refer to the above description of the embodiments, and will not be described here.

[0123] As shown in FIG. 1, Figure 5 The navigation prompting method in the cruising state applied to the navigation server provided in the embodiments of the present disclosure can include the following steps.

[0124] S510, in response to the navigation event acquisition request sent by the navigation client, determining the current position of the vehicle.

[0125] Specifically, the navigation server receives the navigation event acquisition request sent by the navigation client, and parses it to obtain the current position of the vehicle.

[0126] S520, based on the current position, predicting the driving route of the vehicle at a future time, and generating a current driving route.

[0127] Specifically, the navigation server bases on the current position, and uses the historical position, the historical trajectory, the road information in the online map data, and other data of the vehicle and the user's pre-set common place to predict the route that the vehicle is most likely to drive in the future, and obtain the current driving route.

[0128] In an example, S520 includes S521: determining the historical trajectory corresponding to the current position, and fitting the current driving route based on the current position and the historical trajectory.

[0129] Specifically, the historical trajectory of the vehicle can reflect the trend of the vehicle at a future time to some extent. Therefore, the navigation server can obtain the historical trajectory generated by the vehicle in the current driving process before the current time. For example, the navigation event acquisition request sent by the vehicle or the navigation client carries the historical trajectory, and the navigation server can obtain the historical trajectory by analyzing the navigation event acquisition request. For another example, the navigation server can fit the real-time positions reported by the vehicle / navigational client at the historical time to obtain the historical trajectory. For another example, the navigation server stores the historical positions / historical trajectories of the vehicle reported by other vehicles / navigational clients, and the historical trajectory can be read or the historical positions can be fitted to obtain the historical trajectory.

[0130] Then, the navigation server can use the historical trajectory and the current position to predict the trajectory of the vehicle to be driven as the current driving route. For example, the navigation server can first use a method such as data extrapolation to expand the historical trajectory and the current position along the road in the online data map to obtain the position points that the vehicle can drive to at a future time, and then use a data fitting method to fit the position points obtained by expansion to obtain the current driving route. In this way, the prediction accuracy of the current driving route can be improved to some extent, thereby improving the accuracy of the subsequent generated navigation event information, and further improving the accuracy of the navigation prompt.

[0131] In another example, S520 includes S522: generating the current driving route based on the current position and at least two preset locations corresponding to the navigation client.

[0132] The preset locations are preset location positions. For example, the preset locations can be common locations set by the user / driver in the navigation client, such as home address and company address; for another example, the preset locations can be addresses frequently parked by the user / driver or addresses frequently searched by the user / driver, and the like.

[0133] Specifically, the preset locations corresponding to the navigation client can reflect the driving destination of the user / driver to some extent. Therefore, the navigation server can determine the possible destination of the current driving according to the current position and the plurality of preset locations, and generate the current driving route according to the current position and the determined destination in combination with the online map data.

[0134] For example, the navigation client can determine whether the current position is on the way to a preset location, so as to determine which preset location can be used as the destination of the current driving. In order to improve the accuracy of the current driving route, the navigation server can also use information such as whether the current system time matches the time period when the user frequently goes to a preset location, or whether the current position is on the historical route frequently used by the user to go to a preset location.

[0135] The above-mentioned manner of using the preset location can make the predicted current driving route more consistent with the driving habits of the user, thereby improving the prediction accuracy of the current driving route, improving the accuracy of the subsequently generated navigation event information, and further improving the accuracy of the navigation prompts.

[0136] In yet another example, S520 includes S523: generating the current driving route based on the current location, at least one historical location corresponding to the current location, and road information in the online map data.

[0137] Specifically, the navigation server can infer the current driving route based on the historical location, the current location, and the road distribution in the online map data. For example, the navigation server can predict the driving direction of the vehicle based on the historical location and the current location, and then refer to the related technologies of route planning, and combine the road information such as whether the roads are connected in the driving direction, whether the turning angle between the roads is less than a certain angle value, whether the road names are consistent, whether the road grades are consistent, and the like, to predict the current driving route. In this way, the current driving route can be inferred according to the general rules and convenience of the vehicle driving on the road, which can improve the prediction accuracy of the current driving route to a certain extent, thereby improving the accuracy of the subsequently generated navigation event information, and further improving the accuracy of the navigation prompts.

[0138] S530, generating the navigation event information based on the current driving route and the online map data.

[0139] Similarly, the navigation event information includes at least one line type prompt event, and the line type prompt event is a prompt event including a linear prompt interval along the current driving route. The line type prompt event can be a traffic facility prompt event, a traffic state prompt event, or a traffic facility prompt event and a traffic state prompt event.

[0140] In an example, the navigation event information further includes at least one point type prompt event. The point type prompt event can also include a traffic facility prompt event and / or a traffic state prompt event.

[0141] S540, the current driving route and the navigation event information are sent to the navigation client, so that the navigation client prompts the current prompt event in the navigation event information that is triggered by the current location in the case where the current location matches the current driving route.

[0142] Specifically, the navigation server sends the current driving route and the navigation event information to the navigation client, triggering the navigation client to perform the operation of S240.

[0143] In another embodiment, considering the existence of poor network communication conditions of the electronic device where the navigation client is located, or communication traffic limitations, and the like, the communication function of the navigation client with the navigation server can be affected, thereby causing problems such as failure or delay of the navigation prompt function in the cruise state. In this embodiment, the above navigation prompt processing process can be set in the navigation client, that is, the process of obtaining the current driving route and navigation event information, and the process of traffic information prompt in the cruise state are all set in the navigation client. In this way, the offline map data of the navigation client can be used for related processing to reduce the dependence on navigation server communication, and the current driving route is used as an auxiliary to perform positioning matching and navigation event information matching, thereby improving the accuracy of navigation prompt in the cruise state. The offline map data in the present application refers to map data that is downloaded in advance and does not perform network connection communication during use. It can be high-precision map / high-definition map / three-dimensional map, or it can be a relatively low-precision map, such as a navigation map / two-dimensional map.

[0144] Figure 6 A flowchart of a navigation prompt method in a cruise state applied to a navigation client is provided in an embodiment of the present disclosure. The navigation prompt method in the cruise state applied to the navigation client can be executed by a navigation prompt device in the cruise state of the navigation client. The device can be implemented by software and / or hardware, and can be integrated on an electronic device where the navigation client is installed. The electronic device can be, for example, a smart mobile device such as a smartphone, a tablet computer, a palm computer, a notebook computer, or a smart wearable device, which has no hardware connection relationship with a vehicle; or the electronic device can be a vehicle-mounted device such as a car machine, which has a hardware connection relationship with the vehicle.

[0145] It should be noted that the navigation prompt method in the cruise state applied to the navigation client in this embodiment has the same implementation principle as the navigation prompt method in the cruise state applied to the navigation client and the navigation server in each of the above embodiments. Therefore, the explanation of the same or similar terms and steps in this embodiment and in each of the above embodiments can be referred to the description of each of the above embodiments, which will not be repeated here.

[0146] As shown in Figure 6 The navigation prompt method in the cruise state applied to the navigation client provided by the embodiment of the present disclosure can include:

[0147] S610, obtaining the current position of the vehicle.

[0148] S620, based on the current position, predicting the driving route of the vehicle at a future time, and generating a current driving route.

[0149] The navigation client generates the current driving route in the manner described in S520-S523. However, the online map data in the above process is replaced by the offline map data in the navigation client.

[0150] In some embodiments, S620 includes any one of the following:

[0151] determining a historical trajectory corresponding to the current position, and fitting the current driving route based on the current position and the historical trajectory;

[0152] generating the current driving route based on the current position and at least two preset locations corresponding to the navigation client;

[0153] generating the current driving route based on the current position, at least one historical position corresponding to the current position, and road information in the offline map data.

[0154] S630, generating the navigation event information based on the current driving route and the offline map data.

[0155] Similarly, the navigation event information includes at least one line type prompt event, and the line type prompt event is a prompt event including a linear prompt interval along the current driving route. However, since the offline map data does not perform network connection, it cannot obtain some real-time and dynamic information, such as at least one of road congestion degree, traffic accident, road maintenance, and road control, so the navigation event information does not include a traffic state prompt event. Therefore, the above line type prompt event includes a traffic facility prompt event.

[0156] S640, if it is determined that the current position matches the current driving route, prompting the current prompt event in the navigation event information that is triggered by the current position.

[0157] In some embodiments, S640 includes:

[0158] Step A, if it is determined that the current position matches the current driving route, matching the current position with the linear prompt interval, and determining the line type prompt event corresponding to the matched linear prompt interval as the current prompt event;

[0159] Step B, prompting the current prompt event.

[0160] In some embodiments, Step B includes:

[0161] playing the event content of the current prompt event and the current distance between the current position and the event anchor point of the current prompt event within the linear prompt interval of the current prompt event;

[0162] and / or, displaying the event content and the current distance of the current prompt event in the current display page.

[0163] In an example, the broadcasting the event content of the current prompt event and the current distance between the current position and the event anchor point of the current prompt event within the linear prompt interval of the current prompt event comprises:

[0164] If the current position is between the prompt lower limit position and the prompt upper limit position of the linear prompt interval, the event content of the current prompt event and the current distance are broadcasted.

[0165] In another example, the broadcasting the event content of the current prompt event and the current distance between the current position and the event anchor point of the current prompt event within the linear prompt interval of the current prompt event comprises:

[0166] Based on the current position and the prompt upper limit position of the linear prompt interval, a broadcast start road identifier and a broadcast end road identifier are determined from the current driving route;

[0167] Within the road range of the broadcast start road identifier and the broadcast end road identifier, the event content of the current prompt event and the current distance are broadcasted at a preset frequency.

[0168] In some embodiments, the navigation event information further comprises at least one point type prompt event, and the point type prompt event comprises a point-based prompt range. Similarly, the point type prompt event comprises a traffic facility prompt event, and does not include a dynamic traffic state prompt event.

[0169] Correspondingly, S640 comprises:

[0170] If it is determined that the current position matches the current driving route, the current position is matched with the point-based prompt range, and a point type prompt event corresponding to the matched point-based prompt range is determined as the current prompt event;

[0171] The current prompt event is prompted.

[0172] In some embodiments, after S630, the navigation prompting method applied to the cruise state of the navigation client further comprises: if it is determined that the current position does not match the current driving route, proceeding to S610.

[0184] In some embodiments, the current prompt event determining sub-module is specifically configured to:

[0193] The current prompt event is prompted.

[0194] In some embodiments, the current driving route is obtained by the navigation server through fitting the current position and a historical trajectory corresponding to the current position.

[0195] Alternatively, the current driving route is generated by the navigation server through route planning on the current position and at least two preset locations.

[0196] Alternatively, the current driving route is generated by the navigation server through filtering road information in the online map data based on the current position and at least one historical position corresponding to the current position.
