[0031] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0032] The terms "first", "second", and "third", etc. in the specification embodiments and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, including a series of steps or units. The method, system, product, or device is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0033] The disclosed embodiment provides a data processing method, which can be applied to electronic devices, including but not limited to fixed devices and / or mobile devices. For example, fixed devices include but are not limited to servers, and the servers can be cloud servers or ordinary servers. For example, mobile devices include but are not limited to vehicle terminals, navigation devices, mobile phones, tablet computers, etc. Figure 1 As shown, the data processing method includes:

[0034] S101: Determine the target route;

[0035] S102: When the target route includes a left turn scenario, determining a connection path of the left turn scenario and a left turn entry position;

[0036] S103: Starting from a certain distance between the vehicle and the position where the vehicle turns left, navigation prompts are given to the connected path in a preset prompting manner until the vehicle exits the connected path.

[0037] In some implementations, determining the target route includes: acquiring origin information and destination information; and determining the target route based on the origin information and the destination information.

[0038] In some implementations, determining the target route includes: acquiring the vehicle's current location information and destination information; and determining the target route based on the vehicle's current location information and destination information.

[0039] It should be noted that when multiple candidate routes are determined, the target route can be determined based on the candidate route selected by the user; or, the candidate route with the shortest time can be determined as the target route; or, the candidate route with the shortest mileage can be determined as the target route; or, the candidate route with the least number of traffic lights can be determined as the target route.

[0040] It should be noted that after determining the target route, the target route can also be adjusted during driving according to actual conditions such as the current traffic congestion level or the expected arrival time requirements.

[0041] In this embodiment, the target route includes at least one scenario, wherein the scenario is divided into scenarios such as turning left via a detour, turning left normally, going straight, and turning right.

[0042] In the disclosed embodiment, borrowing lane refers to borrowing the opposite lane. The opposite lane is the lane that is opposite to the lane in which the vehicle is currently traveling. The borrowing lane left turn scenario refers to the scenario of using the opposite lane to turn left.

[0043] Here, the connected path of the left turn scenario includes: the entry lane line and the lane line mark of the entry lane line, the passing road line and the lane line mark of the entry lane line, and the exit road line and the lane line mark of the exit road line.

[0044] Here, the entry position for turning left via the detour refers to the location of the gap for turning left via the detour.

[0045] Here, the value of the certain distance can be set or adjusted according to actual conditions such as user needs or current road conditions or system settings.

[0046] Here, the preset prompting method includes but is not limited to: prompting the traffic route corresponding to the connected path in the form of a real-life picture; highlighting the traffic route corresponding to the connected path according to the phase information of the left-turn signal light.

[0047] The technical solution described in the embodiment of the present disclosure determines a target route; when the target route includes a left turn scenario, determines a connection path of the left turn scenario and an entry position for the left turn scenario; when the vehicle travels to within a preset range of the left turn entry position, navigation prompts are given to the connection path in a preset prompting manner; in this way, by prompting the connection path in the left turn scenario in a preset prompting manner, the accuracy and richness of the navigation expression in the left turn scenario can be improved, thereby improving the traffic efficiency in the left turn scenario.

[0048] In some embodiments, the target route includes at least one road line, and the above data processing method may also include: determining the road line identification and road line type of each road line in the at least one road line; when the road line type includes a left turn type, determining that a left turn scenario is involved.

[0049] Among them, a road line type that belongs to the type of left turn via the lane is determined as a road line for entering by turning left via the lane.

[0050] When the target route includes two or more road lines, the tail of the previous road line of the two adjacent road lines is connected to the head of the next road line.

[0051] Here, each road line has a unique road line identifier, that is, different road lines have different road line identifiers.

[0052] Here, the road line types can be divided into left turn via detour, normal left turn, straight ahead, right turn and other types.

[0053] Among them, the normal left turn is relative to the left turn via the detour. The normal left turn does not require occupying the opposite lane. For the normal left turn and the left turn via the detour on the same road line, the starting points of the normal left turn and the left turn via the detour are different.

[0054] Through the above method, whether the target route involves a left turn scenario can be determined based on the road line type of the road line included in the target route, so that whether the target route involves a left turn scenario can be quickly determined, thereby providing a judgment basis for whether a navigation service for a left turn scenario needs to be provided.

[0055] In some embodiments, determining a connectivity path for a detour left turn scenario includes: determining a scene identifier for the detour left turn scenario; and obtaining a connectivity path for the detour left turn scenario from detour left turn associated data based on the scene identifier.

[0056] Here, the left turn-by-lane association data is obtained in advance. How to obtain the left turn-by-lane association data will be described in detail later, and will not be repeated here.

[0057] In some embodiments, the scene identification of the left turn scene is determined according to the identification of the left turn signal light. In other embodiments, the scene identification of the left turn scene is determined according to the identification of the lane entry line. Among them, the identification of the lane entry line, the identification of the left turn signal light, and the identification of the left turn scene correspond to each other.

[0058] Through the above method, the connected path of the left turn scenario can be quickly determined, which helps to improve navigation accuracy.

[0059] In some embodiments, determining the entry position for turning left via a detour includes: determining a gap position of a detour left turn scenario; and determining the entry position for turning left via a detour based on the gap position.

[0060] In some implementations, the gap position of the left turn via lane scenario is obtained by querying the left turn via lane associated data based on the scenario identifier of the left turn via lane scenario.

[0061] The gap is located on the dividing strip between the leftmost lane on the road the vehicle is currently traveling on and the opposite lane. Figure 2 The schematic diagram of the gap in the scenario of turning left via the lane is shown. Figure 2 In the figure, the dotted box area is the notch location.

[0062] Through the above method, the entry position for turning left via the detour can be quickly determined, providing a location reference and a time reference for providing navigation prompts for the left turn scenario via the detour, which helps to provide more detailed and accurate navigation services.

[0063] In some embodiments, starting from a certain distance between the vehicle and the position of the left turn through the lane, a navigation prompt is provided for the connected path in a preset prompting manner, including:

[0064] Starting from a certain distance between the vehicle and the position where the vehicle enters the left turn via the detour, first prompt information about the connected path is output according to the phase information of the left turn signal light, and the first prompt information includes a traffic route map of the connected path.

[0065] Here, the value of the certain distance can be set or adjusted according to user needs or road conditions.

[0066] Here, the phase information of the left-turn signal light is used to indicate when it is allowed to enter the left-turn lane via the detour and when it is prohibited to enter the left-turn lane via the detour.

[0067] In some specific implementations, when the phase information of the left-turn signal light indicates that the current state is green and the vehicle can pass, the first prompt information about the connected path is output in a highlighted display mode; when the phase information of the left-turn signal light indicates that the current state is red and the vehicle cannot pass, the first prompt information about the connected path is output in a non-highlighted display mode. In this way, the vehicle can be reminded to enter the opposite lane at the right time and successfully complete the left turn according to the phase information of the signal light.

[0068] In other specific embodiments, when the phase information of the left-turn signal light indicates that the current state is green and the vehicle can pass, the first prompt information about the connected path is output in a green background display; when the phase information of the left-turn signal light indicates that the current state is red and the vehicle is prohibited from passing, the first prompt information about the connected path is output in a red background display.

[0069] Figure 3A schematic diagram showing a navigation prompt for a connected path in a preset prompt manner is shown, such as Figure 3 As shown, the navigation outputs the route map of the connected path in a highlighted manner, so that the vehicle can be reminded to enter the opposite lane at the right time and complete the left turn smoothly according to the phase information of the left turn signal light.

[0070] Through the above method, the accuracy and richness of the expression of the left-turn scenario can be improved, which helps to provide more detailed and accurate navigation services for the left-turn scenario, thereby improving the traffic efficiency in the left-turn scenario.

[0071] In some embodiments, the data processing method may further include:

[0072] When the vehicle travels to at least one position away from the position for turning left via the detour lane, a second prompt message is output, and the second prompt message is used for broadcasting a prompt to remind the user to enter the left turn lane in the same direction as the vehicle in advance.

[0073] Among them, the left-turn lane is the only lane to enter the target lane.

[0074] The second prompt information is output at a certain number of positions from the vehicle to the position for turning left via the detour, which can be set or adjusted according to user needs or navigation design.

[0075] For example, announcements are made 200 meters, 100 meters, and 50 meters before the left-turn entry position to remind vehicles to keep left and enter the left-turn lane in the same direction as the vehicle.

[0076] Through the above method, the accuracy and richness of the expression of the left-turn scenario can be improved, and a more refined and accurate navigation service can be provided for the left-turn scenario, which helps to improve the traffic efficiency in the left-turn scenario.

[0077] In actual applications, for the same intersection that supports left turns via a detour, some vehicles may be recommended to make a left turn via a detour, while others may not. Since a left turn via a detour may make users worry about driving safety, navigation services can be provided based on the user's choice or driving proficiency. Specifically, for novice drivers, it is recommended that they turn left on the main road as much as possible and avoid the detour left turn area. For experienced drivers, it is recommended that they take the detour left turn area, especially during peak hours, to quickly ease traffic flow.

[0078] In actual applications, after the target route is formed, when the vehicle is traveling along the target route, if a certain intersection suddenly becomes congested, the left turn on the main road can be switched to a left turn on the detour road to facilitate the vehicle to pass through the intersection quickly and safely.

[0079] In some embodiments, the above data processing method may further include: obtaining the scene feature information of the left turn via detour; generating the left turn associated data via detour based on the scene feature information of the left turn via detour, and recording the left turn associated data via detour.

[0080] The disclosed embodiment does not limit how to obtain the scene feature information of the left turn through the lane. For example, the scene feature information of the left turn through the lane is obtained through image data collected by the vehicle. For another example, the scene feature information of the left turn through the lane is obtained from a third-party device.

[0081] The disclosed embodiment does not limit the specific storage location of the left turn associated data. For example, the left turn associated data can be stored in a special database, which can be queried by the navigation device. For another example, the left turn associated data can be stored in a server, which is connected to the navigation device.

[0082] In some implementations, obtaining the feature information of the left turn scene by using another lane includes at least one of the following:

[0083] Get the location information of the entry gap in the scenario of turning left via the lane;

[0084] Get the entry road line and turn arrow information in the left turn scenario;

[0085] Get the lane line and turn arrow information in the left turn scenario;

[0086] Get the exit lane line and turn arrow information in the left turn scenario;

[0087] Get the relevant information of the left-turn signal light in the left-turn scenario.

[0088] Here, the relevant information of the left turn signal light includes identification information of the left turn signal light and control information of the left turn signal light. The control information of the left turn signal light includes: synchronization information of the left turn signal light being red and synchronization information of the left turn signal light being green.

[0089] Figure 4 The schematic diagram of the lane entry line, the starting point of the left turn through the lane and the left turn signal light through the lane is shown, as shown in FIG. Figure 4 As shown in the figure, ① the lane you are in is the entry lane line, and the circle at the gap indicates the starting point of the left turn. Generally, a signal light control facility is required at the gap to prompt the user whether to enter the opposite lane. Figure 4 The left turn signal light located directly in front of the gap and closest to the gap is the left turn signal light for passing through the lane.

[0090] Through the above method, by pre-recording the left turn associated data via the detour, it is possible to provide a calculation basis for the subsequent rapid determination of the connection path of the left turn scenario included in the target route.

[0091] In some embodiments, based on the characteristic information of the left turn scene, the associated data of the left turn via lane is generated, including: based on the characteristic information of the left turn scene, a connection path of the left turn scene is generated; the connection path includes the entry lane line and its lane line marking, the passing road line and its lane line marking, and the exit road line and its lane line marking.

[0092] In the same left turn scenario, there may be multiple connected paths. Figure 5 For example, there is a left turn scenario on L1 road. The turning arrows and connected paths on L1 road are shown in Table 1.

[0093] Serial number Enter the driveway Passing lane Exit Driveway Turn Arrow 1 L1 Lane 1 L5 Lane 1 L4 Lanes 1, 2, 3 Turn left 2 L1 Lane 1 - L4 Lanes 1, 2, 3 Turn left 3 L1 Lane 2 - L3 Lanes 1, 2 straight 4 L1 Lane 3 - L3 Lanes 2, 3 straight 5 L1 Lane 3 - L2 Lanes 1, 2 Turn right

[0094] Table 1

[0095] from Figure 5 As can be seen from Table 1, L1 lane 1 has a left turn scenario, and in its left turn scenario, there are 3 connected paths, namely: L1 lane 1->L5 lane 1->L4 lane 1, L1 lane 1->L5 lane 1->L4 lane 2, L1 lane 1->L5 lane 1->L4 lane 3. L1 lane 1 also has a normal left turn scenario, and in its normal left turn scenario, there are 3 connected paths, namely: L1 lane 1->L4 lane 1, L1 lane 1->L4 lane 2, L1 lane 1->L4 lane 3. L1 lane 2 has a straight-through scenario, and in its straight-through scenario, there are 2 connected paths, namely: L1 lane 2->L3 lane 1, L1 lane 2->L3 lane 2. L1 lane 3 has a straight-through scenario, and in its straight-through scenario, there are 2 connected paths, namely: L1 lane 3->L3 lane 2, L1 lane 3->L3 lane 3. There is a right turn scenario in L1 lane 3, and in its right turn scenario, there are two connected paths, namely: L1 lane 3->L2 lane 1, L1 lane 3->L2 lane 2.

[0096] Through the above method, based on the feature information of the left turn scene, a connection path of the left turn scene is generated, which provides a calculation basis for the subsequent rapid determination of the connection path of the left turn scene in the target route, and helps to improve the efficiency of determining the connection path of the left turn scene.

[0097] Figure 6 A storage form of the left turn associated data is shown, such as Figure 6As shown, the left turn associated data is stored in a table form. Specifically, the road scene table (Road_Sence) is used to record various road scene information. The left turn scene is one of the scenes. It is necessary to record the scene location, scene type, application direction (relative to the road line, whether it is forward or reverse), and the lane number of the scene (the full lane scene can be expressed by -1). The road line table (Road_Link) is used to store basic road line geometry and road direction information. The lane connectivity table (Lane_Topology) is used to record all connectivity relationships under the scene, including the entry road line and the corresponding entry lane number, the corresponding turning arrow; the exit road line and the corresponding exit lane number, the turning arrow. The connected path passing table (Pass_Road) is used to record the passing road lines and corresponding lane numbers of the connected relationship. If there are multiple road lines on a connected path, Seq_Num is used to record the numbers in the forward direction of the vehicle. If the connected path has no passing path, no record is required. The signal light table (Signal_Control) is used to record signal light control information. If there is detailed traffic light switch information, it is recorded in the Phase_Info field (if the information is very complex, the phase information can be recorded in a configuration table). Based on the left turn associated data stored in the above table, in actual application, the starting point and destination are set, and the target route is obtained according to the starting point and destination. It is determined whether there is left turn associated information on the target route, that is, whether the road line ID on the path exists in the road line table and Lane_type contains the left turn area; according to the Sence_Id of the left turn scene, the connectivity relationship in the lane connectivity table is determined, and the entry and exit road lines (including the entry road line and the exit road line) of the left turn are compared to see whether they are in the target route. If the entry and exit road lines of the left turn are in the target route, it is recommended to give a prompt broadcast from the 200, 100, and 50 meters before the entry direction according to the left turn entry position, reminding the vehicle to enter the left turn lane first; and according to the signal light phase information, remind the vehicle to enter the opposite left turn lane when the left turn signal light is green, and supplemented by an enlarged image prompt. If the entry and exit road lines of the left turn are not in the target route, there is no need to give a left turn navigation prompt. In this way, the scenario of turning left via another lane can be better expressed, providing a more refined and accurate navigation application effect, improving the traffic efficiency in the left-turn scenario, and thus improving driving safety.

[0098] It should be understood that Figure 6 The relationship diagram between the tables shown is only schematic, and those skilled in the art can Figure 6 Various obvious changes and / or substitutions can be made to the examples, and the resulting technical solutions still fall within the scope of the disclosure of the embodiments of the present disclosure.
