Embodiments of this disclosure relate to the field of navigation technology, in particular relate to a lane indication method, apparatus and device, a storage medium and a computer program product.
Navigation systems are widely used in in-vehicle terminals. Navigation systems usually include a collection of road functions, including real-time positioning, destination selection, route planning, guidance and the like. Navigation systems provide great convenience for people who travel by driving vehicles.
In related technologies, in the process of driving using a navigation system by a user, the navigation system formulates the target route according to the destination inputted by the user so as to guide the user to drive in accordance with the target route and provide lane information to the user. However, in the above situations, because the navigation system generally only provides an intersection reminder to the user within a designated distance in front of the intersection, there might be a driving error caused by the user's unfamiliarity with road traffic, causing a higher driving error and detour rate.
Embodiments of this disclosure provide a lane indication method, apparatus and device, a storage medium, and a computer program product, which can reduce driving detour rate and improving driving safety. The technical solutions are as follows:
According to one aspect, a lane indication method is provided, the method being executed by a terminal device and the method including: in response to a navigation start operation, displaying a navigation interface, where the navigation start operation indicates performing navigation based on a navigation start position and a navigation end position, the navigation interface is configured to display a navigation route, and the navigation route includes at least one intersection; and in response to being within a prompt range of the current intersection, providing lane prompt information corresponding to a current intersection and lane prompt information corresponding to a subsequent intersection of the current intersection.
According to another aspect, a lane indication apparatus is provided, the apparatus including: a display module configured to display a navigation interface in response to a navigation start operation, where the navigation start operation indicates performing navigation based on a navigation start position and a navigation end position, the navigation interface is configured to display a navigation route, and the navigation route includes at least one intersection; and in response to the apparatus being in a prompt range of the current intersection, provide lane prompt information corresponding to a current intersection and lane prompt information corresponding to a subsequent intersection of the current intersection.
According to still another aspect, a computer device is provided, the computer device including at least one processor and at least one memory, where a computer program is stored in the at least one memory and the computer program is loaded and executed by the at least one processor so as to implement the lane indication method described above.
According to yet another aspect, a non-transitory computer readable storage medium is provided, where a computer program is stored in the computer readable storage medium and the computer program is loaded and executed by at least one processor so as to implement the lane indication method described above.
The beneficial effects brought by the technical solution provided by the embodiments of this disclosure at least include: in response to that the location of the terminal is within the prompt range of the current intersection, displaying at the same time the lane prompt information of the current intersection and the lane prompt information of the subsequent intersection to realize the pre-reminder of the lanes of the current intersection and the subsequent intersection during the navigation process, so as to indicate to the user the intersection situation included in the navigation route and the corresponding lane switching requirements, and reduce the user's tendency to lane change errors when encountering continuous intersections during driving conditions, thereby reducing the driving detour rate, and improving the accuracy and fineness of the lane indication function to ensure the driving safety of the user.
First, the nouns involved in the embodiments of this disclosure are briefly introduced:
Traffic Guidance System (TGS): formulate a planning route according to the navigation start position and navigation end position inputted using a navigation software by a user, and provide the user with the optimal path for guidance, or help the user find the optimal path from the navigation start position to the navigation end position by obtaining real-time traffic information, for example: avoiding the path of the congested road section.
Intelligent Traffic System (ITS), also known as the Intelligent Transportation System, effectively and comprehensively applies advanced science and technology (information technology, computer technology, data communication technology, sensor technology, electronic control technology, automatic control theory, operations research, artificial intelligence, etc.) to transportation, service control and vehicle manufacturing to strengthen the connection among vehicles, roads, and users, thereby forming a comprehensive transportation system that guarantees safety, enhances efficiency, improves the environment, and saves energy.
Intelligent Vehicle Infrastructure Cooperative Systems (IVICS), abbreviated Vehicle Infrastructure Cooperative Systems (VICS), is a development direction of the Intelligent Transportation system (ITS). VICS uses advanced wireless communication and new generation of Internet technologies to implement dynamic real-time information interaction of vehicles and vehicle-infrastructure in all aspects, and carry out vehicle active safety control and road collaborative management based on the acquisition and integration of all-time and all-space dynamic traffic information to fully realize the effective collaboration of people, vehicles and roads, ensure traffic safety, and improve the efficiency of traffic, thus forming a safe, efficient and environmentally friendly road traffic system.
In related technologies, taking in-vehicle navigation as an example, in response to that lane reminders are required during the navigation process of in-vehicle navigation, the in-vehicle terminal generally displays, on the navigation interface, the driving lane corresponding to the current intersection, for example: when there is a need to go straight at the current intersection, prompt information is correspondingly displayed so as to instruct the user to drive on the lane corresponding to straight driving. However, when the distance between the intersections is relatively close, because the user cannot learn the lane driving scheme in the next intersection in time after passing the current intersection, it makes it impossible for the user to drive to the correct lane in time, thus leading to low navigation success rate and causing safety problems.
In the embodiments of this disclosure, regarding lane reminders, in addition to performing prompts on the lanes at the current intersection, the lane reminders will also perform synchronous prompts on the subsequent intersections at the current intersection, thereby increasing the navigation success rate. Illustratively,
In the process of displaying the navigation interface 104, the terminal 101 displays a navigation route 105 on the navigation interface 104. The navigation route 105 is a route determined based on the navigation start position 102 and the navigation end position 103. The navigation route 105 includes at least one intersection. In response to the current location of the terminal 101 being within the prompt range of the current intersection 106, the terminal 101 provides lane prompt information corresponding to the current intersection 106 and lane prompt information corresponding to the subsequent intersection 107 of the current intersection 106, the lane prompt information being used for lane prompting. For example, the lane prompt information indicates the driving direction of the user at the intersection, the location of the lane corresponding to the driving direction at the intersection, the distance between the subsequent intersection 107 and the terminal 101, and the like.
Combined with the above introduction, the application scenarios of the embodiments of this disclosure are exemplified:
1. Application in In-Vehicle Navigation Scenarios
The in-vehicle terminal displays the navigation interface, the navigation route determined by the current position and navigation end position based on the in-vehicle terminal is displayed on the navigation interface, and the navigation route includes at least one intersection. When the vehicle is driven to be within the corresponding prompt range of the current intersection (for example: when it is within 50 meters at the current intersection), the in-vehicle terminal displays the lane prompt information corresponding to the current intersection on the navigation interface, for example: display on the navigation interface the content, “Turn left at the intersection in the front, and it is recommended to take the first lane on the left”; in addition, the in-vehicle terminal also displays synchronously, in the navigation interface, the lane prompt information corresponding to the subsequent intersection of the current intersection. Take the lane prompt information corresponding to the next intersection of the current intersection as an example, for example: the in-vehicle terminal also synchronously displays the content “go straight at the next intersection, and it is recommended to take the two lanes in the middle” on the navigation interface.
2. Application in Autonomous Driving Scenarios
The user starts the autonomous driving by means of the autonomous driving system in the vehicle. At the same time, the navigation interface of the in-vehicle terminal displays the navigation route corresponding to the navigation start position to the navigation end position. The navigation route includes at least one intersection. During the process of autonomous driving, when the vehicle is located within the prompt range of the current intersection, the lane prompt information corresponding to the current intersection is voice broadcast, for example: “turn left at the intersection in the front, and it is recommended to take the first lane on the left”; in addition, the in-vehicle terminal also synchronizes the voice broadcast of the lane prompt information corresponding to the subsequent intersection of the current intersection. Take the lane prompt information corresponding to the next intersection of the current intersection by voice broadcast as an example, for example: the in-vehicle terminal also synchronizes the voice broadcast of “go straight at the next intersection of the current intersection, and it is recommended to take the two lanes in the middle.”
Notably, the application scenarios described above are only illustrative examples, which is not limited in the embodiments of this disclosure.
Illustratively,
A client of a target application program 211 having navigation functions is mounted and operated in the terminal 210. The target application program 211 can be a navigation application program, an instant communication application, a navigation mini-program, or the like, where the navigation mini-program can be a mini-program where any application program serves as the host program, which is not limited in the embodiments of this disclosure.
After determining a navigation start position and a navigation end position, the terminal 210 sends to a server 220 the navigation start position and the navigation end position, the server 220 performs route planning according to the navigation start position and the navigation end position received so as to generate a navigation route and feedback the navigation route to the terminal 210, the terminal 210 displaying the navigation route on the navigation interface. While displaying the navigation route, the terminal 210 will also perform lane prompting on the intersections in the navigation route. Moreover, in the embodiments of this disclosure, in the process of lane prompting, the terminal 210 will at the same time display lane prompt information of at least two intersections (e.g., the current intersection and subsequent intersections of the current intersection).
The terminal 210 can be at least one of smartphones, tablets, portable laptops, desktop computers, smart speakers, smart wearable devices, in-vehicle terminals, smart voice interactive devices, smart appliances and other terminals. The terminal in the embodiments of this disclosure can also be called a terminal device. In some embodiments, the terminal 210 and the server 220 can be realized as the above-mentioned traffic guidance systems, intelligent traffic systems, intelligent vehicle infrastructure cooperative systems, and so on.
In some embodiments, The communication network 230 mentioned above can be realized as a wired network or a wireless network, and the communication network 230 can be realized as any one of a local area network, urban area network, and wide area network, which is not limited in the embodiments of this disclosure.
The server 220 mentioned above can be realized as a cloud server in the cloud, where the cloud server refers to a server using Cloud technology. Cloud technology refers to hosting technology by unifying a series of resources such as hardware, software, and network in the wide area network or local area network so as to achieve computing, storage, processing and sharing of data. Cloud technology is a general term of network technology, information technology, integration technology, management platform technology, application technology, etc. based on cloud computing business model applications, and it can form a resource pool, which is used on demand and flexible and convenient. Cloud computing technology can become important support. The background services of a technology network system require a large number of calculations and storage resources, such as video websites, picture websites, and more portal websites. With the rapid development and application of the Internet industry, each item may have its own identification mark in the future, which needs to be transmitted to a background system for logical processing. Data of different levels are processed separately, and all kinds of industry data need to be supported by powerful systems. And this can only be realized by cloud computing.
In some embodiments, the server 220 described above can also be implemented as a node in a blockchain system. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain, essentially a decentralized database, is a series of data blocks correspondingly generated using cryptographic methods. Each data block contains a batch of network transaction information used for verifying the validity of its information (anti-counterfeiting) and for generating a next block. The blockchain can include a blockchain underlying platform, a platform product service layer, and an application service layer.
In the embodiments of this disclosure, the lane indication method provided in the server 220 is implemented as a business service in the application service layer.
Combining the noun introduction, application scenarios and implementation environment described above, the lane indication method provided by the embodiments of this disclosure will be described, and the method executed by the client mounted and operated in the terminal will be taken as an example. The terminal may correspond to a vehicle that needs navigation. The terminal may be embedded in the vehicle or a separate device placed in the vehicle for navigation. Schematically,
step 301: in response to a navigation start operation, displaying a navigation interface.
The navigation start operation indicates performing navigation based on a navigation start position and a navigation end position. Schematically, the client in the terminal detects the navigation start operation. When the navigation start operation for the user interface of the client by the user is detected, the client displays the navigation interface, and the navigation start operation can be used for instructing the client to generate a navigation route based on the navigation start position and the navigation end position so as to perform navigation. The navigation start operation described above is used for starting navigation; it can refer to an input operation of the navigation start position and the navigation end position, or can refer to a start operation of the target application program above described, which is not limited in the embodiments of this disclosure. The navigation start position can refer to the starting position of navigation, and the navigation end position can refer to the end position of navigation.
In some embodiments, the means for determining the navigation start position can include at least one of the following:
In some embodiments, the means for determining the navigation end position can include at least one of the following:
Notably, the navigation start position and the navigation end position described above are only illustrative examples, which is not limited in the embodiments.
After determining the navigation start position and the navigation end position, the client directly determines the navigation route corresponding to the navigation start position and the navigation end position and starts navigation; or the client displays at least one recommended navigation route corresponding to the navigation start position and the navigation end position, and when a determination operation for one of the navigation routes is received, the client performs navigation according to the navigation route corresponding to the determination operation.
The navigation interface refers to a display interface of the navigation information. The navigation interface can be configured to display a navigation route, and the navigation route includes at least one intersection. In some embodiments, the navigation interface further includes: estimated end time of navigation, estimated travel time of navigation, road congestion, etc. The navigation route mentioned above can be used for guiding the user to drive from the navigation start position to the navigation end position, and the navigation route is the route that the user refers to when driving currently.
In one embodiment, at least one of the intersections described above can be implemented as: at least one of intersections where traffic lights are located, turning intersections, fork intersections, and intersections where road marking lines are located. The intersections where traffic signal lights are located include intersections where traffic light is located, intersections where warning light is located, etc.; turning intersections include sharp turning intersections and U-turn intersections located on roads (such as mountain roads, highways, etc.); fork intersections include merging intersections, diverging intersections (such as high-speed exits), crossing roads (such as T-junctions, crossroads, etc.), etc.; the intersection where road marking lines are located include intersections where pedestrian crossing lines are located, intersections where speed bumps are located, etc., which is not limited in the embodiments of this disclosure.
In some embodiments, the intersection displayed on the current navigation interface is determined by the map range in the navigation interface. In the embodiments of this disclosure, the navigation route between the navigation start position and the navigation end position pass through at least two intersections along the way. No intersection may be displayed on the current navigation interface; or the current intersection is displayed on the current navigation interface; or a plurality of intersections are displayed on the current navigation interface. The displayed number of intersections is related to the range of the map accommodated in the navigation interface, that is, the displayed number of intersections is related to the scaling display ratio of the map in the navigation interface. The larger the scaling of the map (that is, the map is zoomed in), the smaller the area that can be displayed on the navigation interface, and the navigation interface may not be able to display the current intersection or only the current road; The smaller the scaling of the map (that is, the map is zoomed out), the larger the area that can be displayed on the navigation interface, and the current intersection and multiple subsequent intersections can be displayed on the navigation interface.
The scaling of the map is preset, or the scaling of the map is manually adjusted; alternatively, the scaling of the map is correspondingly adjusted in real time according to the distance between the current position of the terminal and the navigation end position, which is not limited in the embodiments of this disclosure.
In some embodiments, the navigation route includes at least one continuous intersection, where the continuous intersection may refer to an intersection where the distance between two adjacent intersections meets the distance requirement. Schematically, the first intersection and the second intersection are two adjacent intersections in the navigation route, and when the distance between the first intersection and the second intersection is less than a distance threshold, it can be determined that the first intersection and the second intersection are continuous intersections.
In some embodiments, the distance between two intersections includes any one of a straight-line distance and a route distance, where the straight-line distance between two intersections refers to the length of the connecting line between the geographic locations of the two intersections; the route distance between two intersections is the total length traveled along the road from the first intersection to the second intersection.
Alternatively, the continuous intersections may also refer to any two adjacent intersections, that is, after passing the first intersection, the next intersection to be passed is the second intersection, then the first intersection and the second intersection are continuous intersections.
Step 302, in response to (e.g., the terminal) being within the prompt range of the current intersection, providing lane prompt information corresponding to the current intersection and lane prompt information corresponding to a subsequent intersection of the current intersection.
The lane prompt information is used for lane prompting, which can indicate the driving direction at the intersection for the user, the location of the lane corresponding to the driving direction at the intersection, the distance between the subsequent intersections and the terminal, and the like. The subsequent intersections refer to the intersections that need to be crossed in the subsequent navigation process after crossing the current intersection on the navigation route. In some embodiments, the subsequent intersection includes at least one intersection after the current intersection in the navigation route.
The prompt range indicates the timing for providing lane prompt information, which can be adaptively set and adjusted. Schematically, when the distance between the terminal and the current intersection is within the prompt range, lane prompt information is provided. For example: assuming that the prompt range is 50 meters, when the user travels to a location within meters from the current intersection, the client will provide lane prompt information.
The distance between the terminal and the current intersection includes any one of a straight-line distance and a route distance. The straight-line distance between the terminal and the current intersection refers to the length of the connecting line between the terminal and the geographic location of the current intersection; The route distance between the terminal and the current intersection refers to the total travel length when traveling from the current position of the terminal to the current intersection along the navigation route.
In some embodiments, the lane prompt information may be advanced auxiliary information provided for the intersection and indicates the intersection situation in advance, so as to help the user or the autonomous driving system understand the driving needs at the intersection in advance and make driving decisions in time. In some embodiments, the lane prompt information can also be driving decision-making auxiliary information provided for the intersection, which is used for prompting the lane distribution information at the intersection in advance; the lane prompt information may also be lane selection auxiliary information provided for navigation routes and intersections, which is used for prompting the user or the autonomous driving system to select lanes at intersections.
Schematically, the lane prompt information can be used for indicating the lane pointing information corresponding to the intersection; alternatively, the lane prompt information can be used for indicating the recommended lane information corresponding to the intersection and the navigation route; alternatively, the lane prompt information can also be used for indicating the distance between the intersection and the designated location; alternatively, the lane prompt information can also be used for indicating the lane flow at the intersection; alternatively, the lane prompt information may also be used for indicating a speed limit requirement at an intersection, etc., which is not limited in the embodiments of this disclosure.
The lane pointing information refers to the lane distribution information corresponding to the intersection. Schematically, the intersection includes four lanes, which are respectively: a first lane-left-turn lane, a second lane-straight lane, a third lane-straight lane, and a fourth lane-right-turn lane; the distribution of the four lanes is the lane pointing information. The lane pointing information facilitates the user to understand the lane distribution corresponding to the intersection in advance before the intersection, so that the user can choose a suitable lane for driving, which improves the effectiveness and rationality of information interaction, thereby improving the rationality and success rate of driving.
The recommended lane information indicates the recommended lane corresponding to the intersection (including the current intersection and the subsequent intersections) in the navigation route, for example: if it is necessary to turn right at the intersection in the navigation route, the recommended lane information is the fourth lane corresponding to the right turn. The recommended lane information facilitates the user to quickly understand the lane that needs to be changed when passing through the intersection during driving, so that the user can change lanes in advance, thereby improving driving safety and reducing driving detour rate.
The distance between the intersection and the specified location includes: the distance between the intersection and the current location of the terminal; or the distance between the intersection and an adjacent intersection. Schematically, when the terminal is located within the prompt range of the current intersection, and the distance between the current location of the terminal and the geographic location of the intersection is 50 meters, the road prompt information at the current intersection includes “the distance from the intersection ahead is 50 meters”. In the case of changing lanes or turning through an intersection, it is convenient for the user to understand the distance between the current location of the terminal and the current intersection during driving, so that the user can change lanes or turn through the intersection within a safe distance. Alternatively, the road prompt information includes “the distance between the intersection ahead and the next intersection is 50 meters”, so as to remind the user to pay attention to the next intersection in advance, thereby further improving driving safety.
The lane flow status refers to the real-time traffic flow corresponding to the lane. Schematically, the lane flow status indicates the real-time traffic flow at the intersection, so that the user can grasp the corresponding intersection flow condition (smooth or congested) in advance, facilitating the user to change routes in time during the driving process and reduce the occurrence of traffic jams, thereby improving the user driving experience.
The speed limit requirement refers to the maximum driving speed for driving through the intersection. For example: if the lane prompt information corresponding to the intersection is “the current intersection speed limit is 60 km/h”, the maximum speed for the user to drive through the current intersection is 60 km/h, thus facilitating the user to adjust the speed in time according to the speed limit requirement of the intersection during driving and reduce the risks of traffic accidents.
In some embodiments, the lane prompt information corresponding to the current intersection includes at least one of the information types described above; the lane prompt information corresponding to the subsequent intersection includes at least one of the information types described above, and the lane prompt information corresponding to the current intersection and the lane prompt information corresponding to the subsequent intersection contain the same or different or partly the same information types, which is not limited in the embodiments.
Schematically, the lane prompt information corresponding to the current intersection includes lane pointing information and recommended lane information, and the lane prompt information corresponding to the subsequent intersection includes recommended lane information. Thus, the lane prompt information corresponding to the current intersection and the lane prompt information corresponding to the subsequent intersection are the same.
In one embodiment, the means of providing lane prompt information may include display screen display and voice broadcast. Schematically, the lane prompt information can be displayed on the display screen of the terminal in the form of text and symbols, and can also be realized by voice broadcast in real time. The presentation form of the lane prompt information corresponding to the current intersection/subsequent intersection can include at least one of the following forms:
The presentation form of the lane prompt information can be any combination of the above forms, for example: display, on the navigation interface, the lane prompt information corresponding to the current intersection, and presenting the lane prompt information corresponding to the subsequent intersection in the form of voice broadcast; or displaying, on the navigation interface, lane prompt information corresponding to the current intersection and lane prompt information corresponding to the subsequent intersection, and presenting the lane prompt information corresponding to the subsequent intersection in the form of voice broadcast. As such, the display flexibility of the navigation prompt information is improved, thereby improving the driving experience of the user. In addition, by means of the voice broadcast, the problem that a user is unable to check the content displayed on the display screen in time when driving through the current intersection can be avoided, the user is enabled to grasp lane conditions of subsequent intersections in advance, and the current navigation interface is simplified, making it convenient for the user to quickly browse the lane prompt information displayed on the navigation interface, thereby further improving driving safety and user driving experience.
Notably, the above-mentioned presentation modes of the lane prompt information corresponding to the current intersection and the subsequent intersections are only illustrative examples, which is not limited in the embodiments.
In one embodiment, when a continuous intersection is realized between the subsequent intersection and the current intersection, the lane prompt information corresponding to the current intersection and the subsequent intersection is displayed. Schematically, the above subsequent intersection is determined by at least one of the following methods:
In one embodiment, in response to the user enabling the advance indication function during the navigation process, the client synchronously provides lane prompt information corresponding to the current intersection and the subsequent intersection. The advance indication function refers to the function of providing in advance the lane prompt information corresponding to the subsequent intersection. When a continuous intersection is realized between the subsequent intersection and the current intersection, the embodiments of this disclosure use the above-mentioned various methods to determine the subsequent intersection, improving the accuracy and comprehensiveness of the determination of the subsequent intersection, thereby improving the display accuracy of the lane prompt information, further reducing the driving detour rate and improving user driving experience.
To sum up, in the method provided by the embodiments of this disclosure, when the location of the terminal is within the prompt range of the current intersection and the lane prompt information of the current intersection and the lane prompt information of the subsequent intersection are simultaneously displayed, pre-reminder of the lanes of the current intersection and subsequent intersections during the navigation process is realized so as to indicate to the user the intersection conditions included in the navigation route and the corresponding lane switching requirements, and to reduce the situation where users encounter continuous intersections during driving and are prone to lane-changing errors, thereby reducing the driving detour rate, and improving the accuracy and fineness of the lane indication function so as to ensure the driving safety of users.
In addition, the presentation form of the above-mentioned lane prompt information can be determined by any combination of display screen display and voice broadcast. Thus, the display flexibility of the navigation prompt information is improved, thereby improving the driving experience of the user. In addition, by means of the voice broadcast, the problem that a user is unable to check the content displayed on the display screen in time when driving through the current intersection can be avoided, the user is enabled to grasp lane conditions of subsequent intersections in advance, and the current navigation interface is simplified, making it convenient for the user to quickly browse the lane prompt information displayed on the navigation interface, thereby further improving driving safety and user driving experience.
In addition, when a continuous intersection is realized between the subsequent intersection and the current intersection, the embodiments of this disclosure use the above-mentioned various methods to determine the subsequent intersection, improving the accuracy and comprehensiveness of the determination of the subsequent intersection, thereby improving the display accuracy of the lane prompt information, further reducing the driving detour rate and improving user driving experience.
In addition, by supporting lane prompt information corresponding to lane pointing information, recommended lane information, the distance between intersections and designated locations, lane flow conditions, speed limit requirements, and other information types, the driving rationality and safety are improved and the driving success rate is increased, thereby improving the user driving experience.
In one embodiment, when the current location corresponding to the terminal is within the prompt range of the current intersection, the number of subsequent intersections of the current intersection can be determined based on various methods. Schematically,
Step 401, in response to receiving a navigation start operation, displaying a navigation interface.
The navigation start operation indicates performing navigation based on a navigation start position and a navigation end position, the navigation interface is configured to display a navigation route, and the navigation route includes at least one intersection. Step 401 is the same as introduced in the above embodiments. For the content not described in the embodiments of this disclosure, reference may be referred to the above embodiments. No further detail will be provided herein.
Step 402, determining a first presentation mode of the lane prompt information corresponding to the current intersection.
The presentation mode refers to the presentation mode of the lane prompt information, and the first presentation mode refers to the presentation mode of the lane prompt information corresponding to the current intersection.
In some embodiments, the first presentation mode of the lane prompt information corresponding to the current intersection may be determined based on the information display strategy. The information display strategy refers to a strategy for providing lane prompt information, such as a strategy for indicating the information type (i.e., display content) and presentation form of the lane prompt information. Schematically, the first representation mode may include at least one of the information type and presentation form of the lane prompt information corresponding to the current intersection, where the information type may include at least one of lane pointing information, recommended lane information, the distance between the intersection and the designated location, lane flow conditions, and speed limit requirements, and the presentation form may include at least one of display screen display and voice broadcast.
That is, according to the information display strategy, the combination mode of the two presentation forms, i.e., display screen display and voice broadcast (e.g., displaying lane prompt information on the display screen or voice broadcasting lane prompt information or voice broadcasting lane prompt information while displaying lane prompt information on the display screen), and the information type corresponding to the lane prompt information of the current intersection (e.g., at least one of the above information types) can be determined, where the display screen may refer to a terminal display screen, such as an in-vehicle terminal, a mobile phone, or the like. In some embodiments, according to different information display strategies, the lane prompt information of the current intersection can be displayed in different combinations. The information display strategy may be preset, or the information display strategy may be determined from candidate strategies, which is not limited in the embodiments of this disclosure.
Step 403, determine a second presentation mode of the lane prompt information corresponding to a subsequent intersection.
The subsequent intersection refers to one or more intersections after the current intersection, which are the same as introduced in the above embodiments. No further detail will be provided herein. The second presentation mode refers to the presentation form of the lane prompt information corresponding to subsequent intersections.
In some embodiments, the second presentation mode of the lane prompt information corresponding to subsequent intersections may be determined based on the information display strategy. Schematically, the second presentation mode includes at least one of the information types and presentation forms of the lane prompt information corresponding to subsequent intersections, where the information types include at least one of lane pointing information, recommended lane information, the distance between the intersection and the designated location, lane flow conditions and speed limit requirements, and the presentation forms include at least one of display screen display and voice broadcast.
In some embodiments, the information display strategy can be used for instructing to provide targeted lane prompt information based on specified requirements, for example: the information display strategy can be used for instructing to provide targeted lane prompt information based on the driving needs of the user or road conditions. In some embodiments, the information display policy includes a display strategy targeting safety; alternatively, the information display strategy includes a display strategy targeting driving speed. Schematically, taking the safety target as an example, the user frequently looks at the navigation during driving and cannot observe the road conditions in time, which is likely to cause safety problems, and thus the information display strategy can be set as an instruction: use the recommended lane information as the information type of the lane prompt information, display the lane prompt information of the current intersection in the form of interface display, and present the lane prompt information of the subsequent intersection in the form of voice broadcast, for example: display “Please take the middle lane at the current intersection” on the interface and voice broadcast “Please take the first lane on the left at the next intersection”.
The lane prompt information corresponding to the current intersection is displayed in a first presentation mode, and the lane prompt information corresponding to the subsequent intersection is displayed in a second presentation mode. In this way, according to the information display strategy, the presentation mode of the lane prompt information is determined from various information types and presentation forms, improving the flexibility of providing lane prompt information, as well as the comprehensiveness and rationality of lane prompt information, thereby improving driving safety.
Step 404, based on the intersection display strategy, determine the subsequent intersections that need to display lane prompt information after the current intersection.
The intersection display strategy refers to the strategy of determining the subsequent intersections that need to display lane prompt information according to the intersection prompt requirements, where the intersection prompt requirements are determined based on safety requirements, speed requirements, and timeliness requirements during driving.
In some embodiments, the intersection display strategy is related to at least one of the distribution of intersections in the navigation route, the dynamic parameters of the driving process, and the static parameters of the driving process. The dynamic parameters are parameters that are dynamically updated in real time according to the driving process, and the static parameters are parameters that remain constant during driving.
The intersection display strategy related to the intersection distribution includes determining that the designated intersection is a subsequent intersection that needs to provide lane prompt information; or determine the subsequent intersection that needs to provide lane prompt information by means of the intersection positional relationship; or determine the subsequent intersection that needs to provide lane prompt information by means of the traffic flow. The method for formulating an intersection display strategy according to the intersection distribution can realize the formulation of the intersection display strategy that is most suitable for the navigation route according to different navigation routes, so that the client can make corresponding adjustments to the lane prompt information that needs to provide subsequent intersections in complex routes.
The intersection display strategy related to the dynamic parameters of the driving process includes determining subsequent intersection that need to provide lane prompt information by means of driving parameters, and the driving parameters may refer to the driving parameters of the vehicle where the terminal is located; or determining the subsequent intersection that needs to provide lane prompt information by means of the navigation phase. The method for formulating an intersection display strategy according to the dynamic parameters of the driving process can realize the corresponding adjustment according to the continuous changes of the dynamic parameters in different driving processes, making it convenient for the user to respond in time when encountering unexpected situations during the driving process.
The intersection display strategy related to the static parameters of the driving process includes determining the subsequent intersection that needs to provide lane prompt information by means of the driving parameters; or determining the subsequent intersection that needs to provide lane prompt information by means of the parameters of the display screen. Formulating the intersection display strategy according to the static parameters of the driving process can realize the formulation of a corresponding intersection display strategy according to vehicles having different static parameters, so that the corresponding intersection display strategy can be better adapted to the vehicles, thereby improving the user driving experience.
In some embodiments, the intersection display strategy can be related to the distribution of intersections in the navigation route and the dynamic parameters of the driving process at the same time, can also be related to the dynamic parameters of the driving process and the static parameters of the driving process at the same time, and can also be related to the distribution of intersections in the navigation route, the dynamic parameters of the driving process, and the static parameters of the driving process at the same time, which is not limited in the embodiments of this disclosure.

In one embodiment, within the number threshold range, the first number is in a positive correlation relationship with the driving speed, that is, when the driving speed reaches a certain level, after the number of lane prompt information corresponding to the subsequent intersection that needs to be provided reaches the number threshold range, the number of subsequent intersections remains unchanged within the maximum number threshold range.
Schematically, please refer to
In some embodiments, the vehicle generally includes an automatic gear (D gear), a sports gear (S gear) and a climbing gear (L gear). In the D gear, the vehicle usually runs at a normal speed on an urban road, for example: 60 km/h; In the S gear, the vehicle usually runs on a smooth road with a high speed limit. In the L gear, the vehicle usually runs on a mountain road, highway and other curved roads. Thus, the second number of subsequent intersections that need to be provided can be determined according to the different driving gears of the vehicle. Schematically, in the D gear, the lane prompt information of the next intersection is displayed; in the S gear, the lane prompt information of two subsequent intersections is displayed; In the L gear, the lane prompt information for three subsequent intersections is displayed.
Notably, the above-mentioned D gears, S gears, and L gears can also be implemented as 3-4 gears, 5-6 gears, and 1-2 gears in manual transmission vehicles respectively.
Schematically, taking the vehicle type as an example, based on the vehicle type of the vehicle to which the terminal belongs, the client provides lane prompt information corresponding to the current intersection, and lane prompt information corresponding to a second number of subsequent intersections after the current intersection. There is a corresponding relationship between the vehicle type and the second number.

In some embodiments, The subsequent intersection is determined based on the intersection location relationship. That is, based on the distance between the current intersection and the subsequent intersection, the client determines a third number of subsequent intersections, and provides lane prompt information corresponding to the current intersection and lane prompt information corresponding to the third number of subsequent intersections.
In some embodiments, the third number of subsequent intersections are determined by at least one of the following methods:
In some embodiments, the first distance requirement or the second distance requirement described above includes a preset distance threshold range; or the first distance requirement or the second distance requirement described above includes a distance threshold range determined according to historical driving data of the terminal, and the first distance requirement and the second distance requirement may be the same or different.
Schematically, the historical driving data correspondingly recorded by the terminal is obtained, where the historical driving data includes the corresponding driving preference, driving duration, historical driving records, etc. during the history driving process. The driving preference includes historical distances from intersections when lane changes are made during historical driving, for example: Terminal 1 started preparing to turn or change lanes at a distance of 110 meters from the intersection many times, and Terminal 2 started preparing to turn or change lanes at a distance of 50 meters from the intersection many times.
It can be understood that the detailed description of this disclosure involve the historical driving data of the corresponding terminal of the user. When the above embodiments of this disclosure need to apply the data to a specific product or technology, it is necessary to obtain permission or consent from the user, and the collection, use and processing of relevant data need to be in compliance with relevant laws, regulations and standards of relevant countries and regions.
In some embodiments, after the client obtains the historical driving data of the terminal, it performs lane change analysis on the historical driving data to obtain the lane change analysis result. Lane change analysis refers to analyzing the lane change situation based on the historical driving data, so as to determine the distance threshold range based on the lane change analysis result. For example: lane change analysis is performed based on the historical driving data corresponding to terminal 1 and the distance threshold range correspondingly configured for the terminal 1 is determined as 50 meters; lane change analysis is performed based on the historical driving data corresponding to terminal 2 and the distance threshold range correspondingly configured for the terminal 2 is determined as 110 meters, in some embodiments, Different terminals are correspondingly configured with the same or different distance threshold ranges, which is not limited in the embodiments of this disclosure.
Schematically, the analysis methods for the lane change analysis include at least one of the following methods:
Notably, the above-mentioned analysis methods for lane change analysis is only schematic examples, and the specific analysis methods for lane change analysis are not limited in the embodiments of this disclosure.
In some embodiments, after performing lane change analysis on the historical driving data, corresponding lane analysis result is obtained, and the lane analysis result is used for predicting the distance of the terminal for lane change in the navigation route, and the distance of the lane change can also be directly used as the distance threshold range, which is not limited in the embodiments of this disclosure. By determining the distance threshold range based on historical driving data, the distance threshold range can be more suitable for users, and the targeted determination of continuous intersections can be realized, thereby improving the display rationality of road prompt information and further improving driving safety.

Step 4045, in response to the terminal being within the prompt range of the current intersection, providing lane prompt information corresponding to the current intersection and lane prompt information corresponding to subsequent intersections based on the navigation phase.

In some embodiments, Based on the navigation phase of the terminal in the navigation route, the client provides lane prompt information corresponding to the current intersection, and lane prompt information corresponding to the fifth number of subsequent intersections after the current intersection, where there is a corresponding relationship between the fifth number and the navigation phase, and the navigation phase is a phase divided according to preset division rules.
In some embodiments, in the initial stage of driving, the user is relatively unfamiliar with the road, so it is necessary to remind the user of multiple intersections so that the user understands and gets familiar with the road; At the end of driving, the user needs more detailed road guidance and more prompts because he is approaching the destination; on designated road sections, for example: on highway sections, because driving errors usually lead to long-distance wrong route driving, it is necessary to increase intersection prompts so as to avoid missing intersections/route deviation problems.
Schematically, in the first 5 km of driving, the client provides lane prompt information corresponding to the current intersection, and lane prompt information corresponding to the subsequent three intersections of the current intersection; in the last 2 km of driving, the client provides lane prompt information corresponding to the current intersection and lane prompt information corresponding to the subsequent two intersections of the current intersection; on highway sections, the client provides lane prompt information corresponding to the current intersection, and lane prompt information corresponding to the subsequent three intersections of the current intersection; on other road sections, the client provides lane prompt information corresponding to the current intersection and the next intersection.

That is, the subsequent intersections are determined based on traffic flow. In some embodiments, based on the traffic flow information corresponding to the navigation route of the terminal, the client provides lane prompt information corresponding to the current intersection, and lane prompt information corresponding to a sixth number of subsequent intersections after the current intersection, where there is a corresponding relationship between the sixth number and the traffic flow.
During the driving process, when the traffic flow is large, the vehicle travels slowly, and the number of subsequent intersections that need to be displayed is relatively small; when the traffic flow is small, the road is relatively smooth, the vehicle travels relatively fast, and the number of subsequent intersections that need to be displayed is relatively large.
Schematically, when the traffic flow is three vehicles per second, the traffic flow is small, and lane prompt information corresponding to the current intersection and lane prompt information corresponding to the subsequent three intersections of the current intersection can be provided; when the traffic flow is eight vehicles per second, the traffic flow is relatively large, and lane prompt information corresponding to the current intersection and the next intersection can be provided.
