For example, when there is a secondary road at the intersection, there may be a behavior of crossing multiple lanes from the leftmost lane directly to the secondary road. For another example, when turning right, there may be a situation where the vehicle makes a right-angle turn to the outermost lane and then gradually drives normally. The first situation mentioned above has the problem of not being "human," and the second situation will bring the safety risk of collision.

[0044] Referring to FIG. 1 , FIG. 1 is a flow chart illustrating the main steps of a method for turning at an intersection according to an embodiment of the present application. As shown in FIG. 1 , the method for turning at an intersection in the embodiment of the present application is applied to a smart device and mainly includes the following steps S101 to S102 .

[0045] Step S101: Obtain a redundant intersection topology corresponding to the intersection to be planned. The redundant intersection topology is a lane link in which the driving probability of the manual driving historical trajectory data at the intersection to be planned is less than a preset probability threshold. The lane link is a topological connection relationship between different lanes in the intersection to be planned that have a predecessor-successor relationship.

[0046] In this embodiment, the intersection redundancy topology corresponding to the intersection to be planned can be obtained, that is, the lane links whose driving probability of the manual driving historical trajectory data in the intersection to be planned is less than a preset probability threshold are obtained.

[0047] In one embodiment, the smart device may be a driving device, a smart car, a robot, or the like.

[0048] In one embodiment, the intersection to be planned may be a left-turn intersection, a right-turn intersection, an intersection where multiple lanes merge into a fewer lanes, an intersection where a main road merges into a secondary road, etc.

[0049] In one embodiment, a server can obtain the intersection redundancy topology of each intersection to be planned based on the manual driving history trajectory data. The server can be a server installed on a smart device or a cloud server.

[0050] Step S102: Path planning is performed for the planned intersection based on the redundant topology of the intersection, so as to enable the smart device to turn at the intersection in the automatic driving state.

[0051] In this embodiment, the planned path can be planned based on the redundant topology of the intersection to avoid turning at the intersection through the redundant topology of the intersection in the automatic driving state.

[0052] Based on the above steps S101 and S102, the embodiment of the present application can obtain the intersection redundancy topology corresponding to the intersection to be planned, and perform path planning for the intersection to be planned based on the intersection redundancy topology, thereby enabling the smart device to turn at the intersection in the autonomous driving state. Through the above configuration, since the intersection redundancy topology in the embodiment of the present application is the lane link whose driving probability of the manual driving historical trajectory data at the intersection to be planned is less than a preset probability threshold, the path planning for the planned path based on the intersection redundancy topology can effectively avoid the lane link with a low driving probability of manual driving in the autonomous driving state, thereby achieving an autonomous driving state closer to the manual driving state, ensuring that the autonomous driving state is more in line with human driving habits and safe turning at the intersection.

[0053] The specific steps of generating the redundant topology of the intersection, step S101 and step S102 are further described below.

[0054] In one implementation of the embodiment of the present application, the present application may further include the following steps S201 and S202 to generate a redundant intersection topology:

[0055] Step S201: Obtain the driving probability of each lane link at the intersection to be planned based on the manual driving history trajectory data at each intersection to be planned.

[0056] In this embodiment, step S201 may include the following steps S2011 to S2013:

[0057] Step S2011: Obtain all lane links in the intersection to be planned.

[0058] In this implementation, all lane links in the intersection to be planned can be obtained. The lane links to be mined can be defined. For example, if a lane has three or more preceding lanes, or if a lane has three or more subsequent lanes, these can be used as scenarios for obtaining the intersection's redundant topology, thereby obtaining all lane links in the current scenario. Lanes corresponding to all preceding separation points of each lane can be obtained from the map as all lane links; alternatively, lanes corresponding to all subsequent separation points of each lane can be obtained from the map as all lane links.

[0059] Please refer to Figures 2 and 3. Figure 2 is a schematic diagram of a lane link from a main road to a secondary road according to an example embodiment of the present application; Figure 3 is a schematic diagram of a lane link for a right turn from lane 1 according to an example embodiment of the present application. As shown in Figure 2, lanes 1 to 9 represent nine lanes, and lanes 1-6, 2-7, 3-8, 4-9, 1-5, 2-5, 3-5, and 4-5 represent all lane links at the intersection. Lane links 1-6, 2-7, 3-8, and 4-9 are for straight-through traffic, while lane links 1-5, 2-5, 3-5, and 4-5 are for main-to-secondary traffic. Without any intervention, in autonomous driving mode, lane links 1-5, 2-5, 3-5, and 4-5 could all be planned paths for the intelligent device. However, lane links 1-5, 2-5, and 3-5 all carry the risk of collision with straight-moving vehicles and are inconsistent with human driver habits. Lane link 1-5, in particular, is very likely to present a collision risk as it passes through three lanes. The lane links for turning from the main road to the auxiliary road in FIG2 can be specifically referred to in Table 1 below.

[0060] Table 1 Lane link table of the main road turning into the auxiliary road in Figure 2

[0061] Among them, lane represents lane, and map version is the map version corresponding to the historical trajectory data of manual driving.

[0062] As shown in Figure 3, lanes 1 through 7 are numbered: 1 is the right-turn lane, and 2 through 7 are lanes for going straight after turning right. 1-2, 1-3, 1-4, 1-5, 1-6, and 1-7 are all lane links at the intersection. Without any intervention, in autonomous driving mode, selecting lanes 2 or 3 would result in a large turning radius and the potential for a collision with a vehicle going straight, which is not in line with human driver habits.

[0063] Step S2012: for each lane link, according to the manual driving history trajectory data, obtain the proportion of the manual driving history trajectory data traveling through the lane link in the manual driving history trajectory data traveling through all lane links.

[0064] In this embodiment, the proportion of the manual driving history trajectory data of each lane link in the manual driving history trajectory data of all lane links can be counted. The manual driving history trajectory data needs to meet the following conditions:

[0065] 1. Changing from one lane to another;

[0066] 2. The trajectory point is within the scope of the planned intersection;

[0067] 3. Non-autonomous driving state;

[0068] 4.The map version is a historical version.

[0069] Step S2013: Obtain the driving probability of the lane link according to the ratio.

[0070] In this embodiment, step S2013 may further include the following steps S20131 and S20132:

[0071] Step S20131: When the ratio is less than or equal to the preset ratio threshold, the driving probability is determined to be 0

[0072] Step S20132: When the ratio is greater than the ratio threshold, the driving probability is determined to be 1.

[0073] In this embodiment, the travel probability can be determined based on the calculated ratio. That is, if the ratio is less than or equal to a preset ratio threshold, the travel probability of the corresponding lane link can be set to 0; if the ratio is greater than the ratio threshold, the travel probability of the corresponding lane link can be set to 1. Those skilled in the art can set the ratio threshold according to actual application needs.

[0074] Continuing to refer to FIG. 2 , Table 2 shows the driving probability of lane links when the main road turns to the auxiliary road in FIG. 2 .

[0075] Table 2 Driving probability table of lane links from main road to auxiliary road in Figure 2

[0076] Step S202: Obtaining the intersection redundancy topology of each intersection to be planned based on the driving probability.

[0077] In this embodiment, lane links with a driving probability less than a preset probability threshold can be used as intersection redundancy topology for the intersection to be planned. Those skilled in the art can set the probability threshold value according to actual application needs.

[0078] In one implementation of the embodiment of the present application, step S101 may be further configured as follows:

[0079] Obtain the intersection redundancy topology through the cloud server; and send the intersection redundancy topology along with the map to the smart device to obtain the intersection redundancy topology; wherein the smart device is in communication with the cloud server.

[0080] In this embodiment, when a new version of the map is released, the intersection redundant topology obtained based on the manual driving history trajectory data corresponding to the previous version of the map can be sent to the smart device along with the new version of the map through the cloud server.

[0081] In one embodiment, the redundant topology of intersections can be stored in a dynamic layer of a new version of the map, and sent to smart devices along with the dynamic layer and the map, so that the smart devices can eliminate the redundant topology of intersections from path planning based on the redundant topology of intersections in the dynamic layer.

[0082] Continuing with Figure 2, Table 3 shows how, when a new map version is released, redundant intersection topologies obtained based on the manual driving history trajectory data corresponding to the previous map version are merged into the dynamic layer of the new map version. If the redundant intersection topology already exists in the dynamic layer of the new map version, it can be updated. If it does not exist in the dynamic layer of the new map version, the obtained redundant intersection topology can be added to the dynamic layer.

[0083] Table 3 Redundant topology information table of intersections stored in dynamic layers

[0084] Among them, the map version in Table 3 is the new version.

[0085] If the redundant topology of the intersection fails to be stored in the dynamic layer, the failed data can be saved as a file for manual confirmation or deletion.

[0086] In one implementation of the embodiment of the present application, step S102 may further include the following steps S1021 and S1022:

[0087] Step S1021: According to the lane in which the smart device is currently located, all lane links of the smart device at the intersection to be planned are obtained.

[0088] Step S1022: removing lane links corresponding to the redundant topology of the intersection from all lane links to implement path planning.

[0089] In this embodiment, when the smart device enters autonomous driving mode, it can obtain all lane links at the intersection to be planned based on the smart device's current lane and eliminate lane links corresponding to redundant intersection topology. Specifically, when the smart device performs route calculation, it can eliminate lane links with a zero driving probability from the map's dynamic layer. These zero-probability lane links are not considered during route planning, thereby achieving a safer and more human-friendly driving experience.

[0090] Please refer to Figure 4 below. Taking the intelligent device as a vehicle and the intersection redundant topology as generated by the cloud server as an example, the intersection turning method of the present application is explained. Figure 4 is a schematic diagram of the main implementation architecture of the intersection turning method according to an embodiment of the present application. As shown in Figure 4, the cloud server performs redundant scene data extraction services based on the map data of the data source in the data storage to obtain the manual driving history trajectory data that meets the conditions; the probability calculation service calculates the driving probability of each lane link based on the manual driving history trajectory data through the data development and governance platform to obtain the calculation results; the calculation results are stored in the data source, and the inheritance service is implemented through the application data platform, and the dynamic layer service in the new version of the map is updated based on the calculation results of the driving probability. The updated dynamic layer service is sent to the vehicle end, and the map module of the vehicle end receives the data and performs path planning (PNC) based on the received data to realize the vehicle control behavior in the automatic driving state.
