As mentioned above, in an application scenario where multiple people travel together by car (for example, a scenario where multiple people at different locations need to travel by the same car), there is a need to further optimize a navigation route. In the scenario where multiple people travel together by car, a vehicle driver may need to pick up multiple passengers on multiple unfamiliar road sections and go to one or more destinations. Sometimes there may be multiple stops and pick-ups in the middle, which poses challenges for route selection, pick-up point selection and location information exchange.
In the related art, the vehicle driver and the multiple passengers can communicate via telephones or social software to determine their respective locations, and plan their respective paths, for example, by manually querying a map. However, the path provided by this method may not be the optimal solution, and there are many drawbacks. For example, the pick-up point may be too far away from the vehicle driver or some passengers, which takes too much time for the vehicle driver or some passengers to get to the pick-up point; and when the road condition information is uncertain, the planned pick-up point may be inconvenient for parking and so on.
The present disclosure provides a computer-implemented method. According to a location of a passenger's terminal device, a plurality of candidate pick-up points are determined, a total time cost that can represent the overall travel cost of the vehicle driver and a plurality of passengers is introduced, through a mode of minimizing the total time cost, at least one target pick-up point is determined from the plurality of candidate pick-up points, and a navigation path is determined for a vehicle driver's terminal device based on at least the at least one target pick-up point. Therefore, a location of the determined at least one target pick-up point enables the overall travel cost of the vehicle driver and the plurality of passengers to be optimized, the driver and the passengers may successfully complete the pick-up at the at least one target pick-up point, and the vehicle driver and the passengers do not need to communicate their respective locations for many times, so that user experience of the vehicle driver and the passengers is improved.
In the technical solution of the present disclosure, the collection, storage, usage, processing, transmission, provision and disclosure of the user's personal information involved are all in compliance with relevant laws and regulations, and do not violate public order and good customs.

step S210, obtain a location of a vehicle driver's terminal device, a location of a first passenger's terminal device and a location of a second passenger's terminal device and a location of a destination;
step S220, determine a plurality of candidate pick-up points according to the location of the first passenger's terminal device and the location of the second passenger's terminal device;
step S230, determine at least one target pick-up point from the plurality of candidate pick-up points, in such a manner that a total time cost from the location of the vehicle driver's terminal device to the location of the destination to be minimum when the first passenger's terminal device and the second passenger's terminal device are picked up from a respective target pick-up point in the at least one target pick-up point; and
step S240, determine a first navigation path for the vehicle driver's terminal device based on at least a location of the at least one target pick-up point.
Therefore, by determining the plurality of candidate pick-up points according to the location of a passenger's terminal device, the total time cost that can represent overall travel cost of a vehicle driver and a plurality of passengers is introduced, through a mode of minimizing the total time cost, at least one target pick-up point is determined from the plurality of candidate pick-up points, and the navigation path is determined for the vehicle driver's terminal device based on at least the at least one target pick-up point. Therefore, a location of the determined at least one target pick-up point enables the overall travel cost of the vehicle driver and the plurality of passengers to be optimized, and the driver and the passengers may successfully complete the pick-up at the at least one target pick-up point, so that user experience of the vehicle driver and the passengers is improved.
The vehicle driver's terminal device may be a mobile device (such as a smart phone, a smart watch, a tablet computer and the like) used by the vehicle driver, or a vehicle-mounted device (such as a vehicle-mounted central control screen, a vehicle head-up display and the like).
The passenger's terminal device may be a mobile device (such as a smart phone, a smart watch, a tablet computer and the like) used by the passenger.
According to some embodiments, a distance between a location of each of the plurality of candidate pick-up points determined in step S220 and the location of the first passenger's terminal device may be smaller than a first threshold, and a distance between the location of each of the plurality of candidate pick-up points and the location of the second passenger's terminal device may be smaller than the first threshold.
Since the determined distances between the location of each candidate pick-up point and the locations of the first passenger's terminal device and the second passenger's terminal device are smaller than the first threshold, so that time costs of a first passenger and a second passenger to each candidate pick-up point are both within an acceptable range of the corresponding passengers, thus further optimizing costs of the first passenger and the second passenger to travel by car.
It should be understood that different first thresholds may be set according to an actual situation of a city map. For example, the first threshold may be 500 meters or 1000 meters, which will not be repeated here.
step S321, determine a candidate region covering the location of the first passenger's terminal device and the location of the second passenger's terminal device; and
step S322, query a plurality of pre-marked landmarks in the candidate region as the plurality of candidate pick-up points.
In step S321, the region may be a circular region with the smallest area that can cover the locations of the first passenger's terminal device and the second passenger's terminal device.
By querying the plurality of pre-marked landmarks (such as a plurality of pre-marked buildings, stations and the like in the map) in the candidate region, since the plurality of landmarks are pre-marked, the vehicle driver or passengers can easily find the landmarks in the navigation map or in the real world, so that they can quickly and easily reach the pick-up point. In addition, since the plurality of landmarks are located in the candidate region (for example, less than 500 meters from a location of each passenger), and the time costs of the passengers to go to each landmark is within the acceptable range of the corresponding passengers.
step S421, determine a sub-navigation path from the location of the first passenger's terminal device to the location of the second passenger's terminal device;
step S422, determine a plurality of path locations from the sub-navigation path; and
step S423, query, for each of the plurality of path locations, a plurality of pre-marked landmarks within a preset distance range of this path location as the plurality of candidate pick-up points.
In step S421, the determined sub-navigation path may be, for example, a walkable path in the map from the location of the first passenger's terminal device to the location of the second passenger's terminal device. In some examples, some locations in the sub-navigation path may be farther than a certain distance (such as 500 meters) from the location of the first passenger's terminal device or from the location of the second passenger's terminal device, but these locations in the sub-navigation path may be convenient for the vehicle driver to find and to park .
Therefore, by querying the plurality of pre-marked landmarks (such as the plurality of pre-marked buildings, stations and the like in the map) around a plurality of path locations in the sub-navigation path, since the plurality of landmarks are pre-marked, the vehicle driver or the passengers can easily find the landmarks in the navigation map or in the real world, so that they can quickly and easily reach the pick-up point and board.
According to some embodiments, a distance between the location of the first passenger's terminal device and the location of the second passenger's terminal device may be smaller than a second threshold.
It can be seen that, on the one hand, when the distance between the location of the first passenger's terminal device and the location of the second passenger's terminal device is smaller than the second threshold (such as 1 kilometer), the method described above is performed on the first passenger's terminal device and the second passenger's terminal device, so as to provide them with a target pick-up point. That is, the vehicle driver and the passengers may gather at the target pick-up point. On the other hand, when the distance between the location of the first passenger's terminal device and the location of the second passenger's terminal device is greater than the second threshold, the plurality of candidate pick-up points and at least one target pick-up point are not determined for the two passenger's terminal devices, but the vehicle driver picks up the two passengers respectively. Therefore, for passengers who are currently far away, it can avoid increasing too much time costs due to the need to go to the pick-up point, so that the overall travel cost can be further optimized, and the user experience of the passengers can be improved.
According to some embodiments, the second threshold may be a ratio of: the distance from the location of the first passenger's terminal device to the location of the second passenger's terminal device; and a navigation distance from the location of the vehicle driver's terminal device to the location of the destination.
Therefore, when the distance from the location of the first passenger's terminal device to the location of the second passenger's terminal device is relatively small relative to a distance of an entire journey (namely, the navigation distance from the location of the vehicle driver's terminal device to the location of the destination), the target pick-up point may be provided to the two passenger's terminal devices; on the contrary, the target pick-up point is not provided to the two passenger's terminal devices. For example, when the distance of the entire journey is 5 kilometers, and the distance from the location of the first passenger's terminal device to the location of the second passenger's terminal device is 1 kilometer, the vehicle driver may pick up the two passengers respectively; and when the distance of the entire journey is 5 kilometers, and the distance from the location of the first passenger's terminal device to the location of the second passenger's terminal device is 500 meters, the target pick-up point may be provided to the two passengers, and the vehicle driver picks up the two passengers at the target pick-up point. Therefore, the flexible choice of whether to provide the target pick-up point for the passengers according to the distance of the entire journey can further optimize the overall travel cost of the vehicle driver and the plurality of passengers, so that the user experience of the vehicle driver and the passengers is further improved.
According to some embodiments, the above total time cost may include a vehicle driver sub-cost and a passenger sub-cost. In addition, for each of the plurality of candidate pick-up points: the vehicle driver sub-cost is determined based on the location of the vehicle driver's terminal device, the location of the destination and location of the candidate pick-up point, and the passenger sub-cost is determined based on the locations of the first passenger's terminal device and the second passenger's terminal device and the location of the candidate pick-up point.
The vehicle driver sub-cost and the passenger sub-cost in the total time cost are considered separately, wherein the locations of the candidate pick-up points can affect the above two sub-costs respectively. Therefore, when minimizing the total time cost, we can understand the impact of selecting different candidate pick-up points on the driver and the passengers respectively.
According to some embodiments, the vehicle driver sub-cost may be a difference between: a navigation distance from the location of the vehicle driver's terminal device to the location of the destination via the location of the candidate pick-up point, and a reference navigation distance from the location of the vehicle driver's terminal device to the location of the destination. In addition, the passenger sub-cost may be a sum of a navigation distance from the location of the first passenger's terminal device to the location of the candidate pick-up point and a navigation distance from the location of the second passenger's terminal device to the location of the candidate pick-up point.
The reference navigation distance from the location of the vehicle driver's terminal device to the location of the destination refers to a navigation distance directly from the location of the vehicle driver's terminal device to the location of the destination without passing another pick-up point.
The extra distance traveled by the vehicle driver relative to the reference navigation distance in order to reach the target pick-up point is taken as the vehicle driver sub-cost; and the extra distance traveled by the passengers in order to reach the target pick-up point is taken as the passenger sub-cost. Since the above distances can be quickly obtained based on navigation data in the map, the time costs of the vehicle driver and the passengers can be simply and accurately calculated respectively, so that it is ensured that the calculation of the travel costs of the passengers and the driver is more accurate.
According to some embodiments, the total time cost may be determined by the following equation:
K=α·K
d
+β·K
p
+γ·N
where K is the total time cost, Kd is the above vehicle driver sub-cost, Kp is the above passenger sub-cost, N is the number of the candidate pick-up points, α is a weight of the vehicle driver sub-cost, β is a weight of the passenger sub-cost and γ is a weight of the number of the pick-up points. Therefore, by setting corresponding weights for different parameters in the total time cost respectively, the weights may be adjusted more targeted for different road conditions or user conditions, so as to adjust the influence of the corresponding parameters on the total time cost. For example, in a scenario where the passengers are inconvenient to move, the total time cost may be optimized by increasing the passenger sub-cost weight β, for example, in a scenario where the road conditions around the pick-up point may be complicated, the influence of the number N of the candidate pick-up points on the total time cost may be increased by increasing the number weight y of the pick-up point, so as to optimize the total time cost, so that the finally determined target pick-up point and the corresponding navigation path enable the total time cost of the driver and the passengers to be optimized.
It should be understood that although a plurality of possible examples of the total time cost are given above, more examples of the total time cost are also possible. For example, the total time cost may be in positive correlation to the square of the values of the plurality of above sub-costs; or the total time cost may be in positive correlation to the square of the number N of the pick-up points. The parameters of the total time cost may be finely adjusted according to the urban road conditions or personal habits of users.
According to some embodiments, step S240, determine a navigation path for the vehicle driver's terminal device based on at least the location of the at least one target pick-up point may include: determine, for the vehicle driver's terminal device, the navigation path from the location of the vehicle driver's terminal device to the location of the destination via the location of the at least one target pick-up point.
After determining the target pick-up point, the corresponding navigation path is determined for the vehicle driver. Therefore, the vehicle driver does not need to perform manual navigation according to the target pick-up point, and for example, the vehicle driver may view the navigation path to the destination passing through the target pick-up point on the vehicle driver's terminal device, which saves time of the vehicle driver, and the driving risk caused by frequency viewing or operating the vehicle driver's terminal device to query the route during driving can also be avoided.
In step S550, a second navigation path may further be determined for at least one of the first passenger's terminal device and the second passenger's terminal device based on at least the location of the at least one target pick-up point. Therefore, the passengers may also view the navigation path to the target pick-up point on the corresponding passenger's terminal device and navigate accordingly, which improves convenience for the passengers.
Below, the navigating method according to the embodiment of the present disclosure will be further descried with reference to
It should be understood that although
Firstly, a location of the vehicle driver's terminal device 610, locations of the plurality of passenger's terminal devices 621, 622 and 623 and a location of the destination 630 may be obtained by a server.
Here, it is assumed that a distance between the locations of the first passenger's terminal device 621 and the second passenger's terminal device 622 is smaller than a second threshold (such as 1 kilometer), and distances between the location of the third passenger's terminal device 623 and the locations of the first passenger's terminal device 621 and the second passenger's terminal device 622 are greater than the second threshold. Therefore, for the first passenger's terminal device 621 and the second passenger's terminal device 622, a plurality of candidate pick-up points may be further provided to them, and since the third passenger's terminal device 623 is far from the first two, the third passenger's terminal device 623 may be picked up alone.
The plurality of candidate pick-up points 641, 642, 643 and 644 may be determined according to the locations of the first passenger's terminal device 621 and the second passenger's terminal device 622. In
Here, a candidate region 650 covering the locations of the first passenger's terminal device 621 and the second passenger's terminal device 622 may be firstly determined; and then a plurality of pre-marked landmarks (such as pre-marked buildings in a map) are queried in the candidate region 650 as the plurality of candidate pick-up points 641, 642, 643 and 644. Of course, a sub-navigation path from the location of the first passenger's terminal device 621 to the location of the second passenger's terminal device 622 may also be firstly determined; then a plurality of path locations are determined from the sub-navigation path; and then the plurality of pre-marked landmarks are queried within a preset distance range of each path location in the plurality of path locations as the plurality of candidate pick-up points 641, 642, 643 and 644.
Then, at least one target pick-up point may be determined from the plurality of candidate pick-up points 641, 642, 643 and 644 by minimizing the total time cost. For example, the additional time cost (the consumed distance compared with direct driving to the destination 630) required by the vehicle driver to pass through each candidate pick-up point is calculated, the additional time costs required by the first passenger's terminal device 621 and the second passenger's terminal device 622 to reach each candidate pick-up point respectively are calculated, and the time costs required by the first passenger's terminal device 621 and the second passenger's terminal device 622 to go to one candidate pick-up point together or go to two candidate pick-up points respectively are calculated (for example, a product of the number of the candidate pick-up points and the corresponding weights is calculated), and then a sum of the above costs is minimized, so that at least one target pick-up point that enables the total time cost to be minimum may be determined from the plurality of candidate pick-up points.
For example, the candidate pick-up point 643 may be determined as the target pick-up point. Therefore, for example, as simply illustrated by an arrow in

According to some embodiments, the first determining unit 720 may be further configured to: determine a candidate region covering the location of the first passenger's terminal device and the location of the second passenger's terminal device; and query a plurality of pre-marked landmarks in the candidate region as the plurality of candidate pick-up points.
