The reasons for the drift of the vehicle icon representing the driver position displayed on the third party application may be environmental factors, signal transmission factors, insufficient hardware setting and other factors, for example, when the vehicle runs in a tunnel or a place covered by a high building, the signal intensity of the GPS is weaker, the positioning signal of the driver can be affected, the frequency of calling an interface provided by a network vehicle provider by the third party application is lower than the frequency of acquiring normal position information, and the third party application lacks auxiliary information such as base station information of a mobile operation network, speed information of the driver, wiFi information and the like to adjust the driver positioning, and the third party application cannot accurately estimate the position of the driver due to the lack of the excessively discrete position information and the auxiliary information.

The terminal 120 is provided with an application program APP with a network taxi service function, and the APP obtains the position information of a driver side provided by a network taxi operator through the computer equipment 110.

An application scene of the embodiment is a scene that a user performs network vehicle-restraining through a third party application program, and when the user needs to use the vehicle, the user can enter a vehicle-using interface through the third party application on the operation terminal, and the vehicle-using interface is provided with a map so as to display the position of a vehicle nearby the user to the user through the map, thereby achieving the purpose of guiding the user to quickly find the vehicle.

In order to avoid the situation of vehicle icon drifting in the process, the embodiment provides a method for acquiring the position of the driver, which is used for adjusting the position information of the driver acquired from the operator side based on the bias factor and the distance factor, predicting the effective position of the driver, comparing the received position information of the driver-side vehicle with the actual position information of the driver-side vehicle after the network vehicle order is completed, generating an error set of each road, updating the bias factor and the distance factor according to the error set, so that the calculation of the effective position is more accurate, the calculation precision of the effective position is further improved, the drifting of the vehicle icon on a passenger vehicle page is reduced, and the consistency of the position of the driver-side vehicle displayed on a vehicle interface and the actual position of the driver-side vehicle is improved.

The present embodiment takes a server as an implementation subject, for example, the implementation subject is the computer device 110 of fig. 1.

As shown in fig. 2, in one embodiment, a method for acquiring a driver end position includes the following steps S201 to S203:

s201, obtaining the observing position of the driver-side vehicle.

It can be understood that, because the driver and the passenger belong to users of two different applications, the third party application cannot directly obtain the position information of the driver-side vehicle, and in addition, the environmental factors, the signal transmission factors, the hardware setting deficiency and other factors exist, so that the position of the driver-side vehicle obtained by the third party application program from the network vehicle supply platform may deviate from the actual position of the driver-side vehicle.

Thus, in this embodiment, the observed position of the driver-side vehicle is a position acquired by an application program, which is a third party application, and the application program acquires the driver position from the network vehicle supply platform.

In one example, the travel path of the driver of the network vehicle generally follows the travel path given by the network vehicle platform, and the travel path of the driver generally corresponds to the preset path, so that the rule can be used as a basis for adjusting the position of the driver, and it can be understood that when the driver receives the network vehicle order, the driver needs to go to the receiving point according to the order information, so that the position of the driver when receiving the order is the starting point of the vehicle at the driver end. Therefore, in the present embodiment, before acquiring the observation position of the driver, it further includes: acquiring an initial position of a driver when receiving an order of a network vehicle, and acquiring a guest receiving point displayed in the order of the network vehicle; and taking the initial position as a starting point, taking the guest point as an end point, obtaining at least one planned path, and taking the starting point as the initial effective position of the driver-side vehicle. And the planned path and the initial effective position can be stored so as to facilitate the calculation of the subsequent effective position and the target path.

S202, adjusting the observation position according to the bias factor and the distance factor to obtain the effective position of the driver-side vehicle.

In this embodiment, the server stores road network information in advance, the road network is a virtual map of actual roads, and any one of the actual roads can find the road network road corresponding to the actual road in the road network.

In the prior art, the projection point of the observation position to the nearest road on the road network is directly used as the effective position, for example, the display position of the observation position on the road network is A, the road adjacent to A is provided with a road M and a road N, the vertical distance between the observation position A and the road M is larger than the vertical distance between the observation position A and the road N, at this time, the projection position of the observation position A on the road N is used as the effective position of the observation position A, however, in the case that a plurality of bidirectional single-way roads separated by green belts exist in urban roads, the road M and the road N are roads with opposite directions, and the method can enable the observation position A to be projected on the opposite single-way roads. In addition, at intersections of urban roads, vehicles may slowly move due to congestion or be stationary due to traffic lights. In this case, the error in the observation position is much larger than the actual displacement of the vehicle, and the disturbance is more strong, and in this case, the observation position may be distributed on each side of the intersection.

Therefore, the embodiment adjusts the observation position according to the bias factor and the distance factor to obtain the effective position of the driver-side vehicle. In this embodiment, the bias factor is used to project the observation position onto the target path, for example, when the observation position satisfies the correspondence relationship with the bias factor. The distance factor is used to control the update frequency of the effective position of the driver-side vehicle, for example, when the observed position satisfies the correspondence relationship with the distance factor, the effective position is updated. Therefore, the observation position is longitudinally adjusted through the bias factor, the observation position of a driver is reasonably projected onto the target path, and the projection of the observation position on the target path is transversely adjusted through the distance factor, so that an effective position is obtained, the influence of noise on the positioning of the vehicle during slow running or static state of the vehicle can be reduced, and the situation that the vehicle position at the driver end is updated slowly and the user experience is influenced is avoided.

In this embodiment, fig. 3 is a schematic diagram showing a process of obtaining an effective position of a driver, and referring to fig. 3, an observation position is adjusted according to a bias factor and a distance factor to obtain the effective position of a driver-side vehicle, which includes steps S301 to S303 as follows:

s301, acquiring a road closest to an observation position according to preset road network information, and taking the road as a reference path.

As can be seen from the above embodiments, the observation position may be correct, or there may be a deviation, and when the observation position is the correct position, the road closest to the observation position may be the target path, so the embodiment obtains the road closest to the observation position on the road network as the reference path. The reference path may be one of the planned paths.

S302, determining a target path according to the distance relation between the observation position and the reference path and each planning path.

In this embodiment, the target path is one of any planned path and a reference path. In one example, the planned path may include T1, T2, and T3 … Tn, and it is understood that the reference path is the road closest to the observation position, and there is only one reference path, and this embodiment refers to the reference path as T. Then in this embodiment the target path is one of T, T1, T2, T3 … Tn at any one time.

In this embodiment, determining the target path according to the distance relation between the observation position and the reference path and each planned path, includes: calculating the distance between the observation position and each planning path to obtain a planning path with the minimum distance as an alternative path; calculating a first distance between the observed position and the alternative path, and calculating a second distance between the observed position and the reference path; when the difference between the first distance and the second distance is smaller than the bias factor, the alternative path is taken as a target path; and when the difference between the first distance and the second distance is greater than or equal to the bias factor, taking the reference path as a target path.

Continuing with the example above, the planned path includes T1, T2, T3 … Tn, with the reference path being T. The first distances from the observation position to each planned path are S1, S2, S3 … Sn, respectively, and if the minimum value of S1, S2, S3 … Sn is S2, the alternative path is T2. And if the second distance from the observation position to the reference path T is S, the difference between the first distance and the second distance is a1, a1= |S2-S|, and when a1 is smaller than the bias factor lambda, the alternative path T2 is taken as a target path. When a1 is greater than or equal to the bias factor λ, the reference path T is taken as the target path.

By the method, the bias factor lambda is introduced to optimize the selection of the target path, so that the selection accuracy of the target path can be improved. It will be appreciated that when the offset factor λ is 0, the observed position will be projected directly onto the reference path, and when the offset factor λ is infinity, the observed position will be projected directly onto any one of the planned paths, failing to reflect the actual travel path of the driver-side vehicle. Therefore, the more accurate the value of the bias factor λ of the present embodiment, the more accurate the selection of the target path of the present embodiment.

S303, obtaining the effective position of the driver-side vehicle according to the projection position of the observation position on the target path and the distance factor.

It can be understood that the position of the vehicle is continuously changed in the running process, so as to reduce the influence of noise on the positioning of the vehicle when the vehicle runs slowly or is stationary, and avoid the influence on the user experience caused by slow updating of the vehicle position at the driver end. The present embodiment introduces a distance factor S _t When the distance between the effective positions of two adjacent moments is greater than S _t When the valid position is updated.

Specifically, in this embodiment, obtaining the effective position of the driver-side vehicle according to the projection position of the observation position on the target path and the distance factor includes: acquiring an effective position at a preset moment; and when the distance between the projection position of the observation position on the target path and the effective position at the preset moment is larger than the distance factor, taking the projection position of the observation position on the target path as the effective position.

In this embodiment, the preset time is the calculation time of the last valid position. In one example, if the target path is T2, the observed position is A, the projected position of the observed position on the target path is B, the effective position at the last time is C, and the position C is on the target path T2, the distance between the position B and the position C is greater than the distance factor S _t And storing the position B as the effective position at the current moment. If the distance between the projection position of the observation position on the target path and the effective position at the last moment is smaller than the distance factor, the observation position of the driver is acquired again, and step S301 is executed again.

By the method, the distance factor S is introduced _t So that the vehicle travels by a distance factor S _t Then updating is performed, and the updating frequency of the effective position is controlled. It will be appreciated that when S _t When=0, the projection position of each observation position on the target path is taken as the effective position, when S _t At infinity, all observed positions will be ignored, and the driver's position updates slowly, affecting the user experience. Thus, the distance factor S of the present embodiment _t The more accurate the value of (c), the more accurate the selection of the effective position in this embodiment.

After obtaining the effective position of the driver, the method of the present embodiment further includes: and judging whether the effective position is on any planning path, if so, continuing to calculate the next effective position, and if not, recalculating the planning path.

For example, if the planned route includes T1, T2, and T3, and the effective position obtained in step S303 is a point on T2, the calculation of the next effective position is continued, and if the effective position obtained in step S303 is not on any one of T1, T2, and T3, there may be a possibility that the driver changes the route or the passenger modifies the address, the planned route is recalculated at this time, that is, steps S201 to S202 are re-executed.

S203, the effective position of the driver side vehicle is sent to the passenger terminal.

In this embodiment, in order to enable the driver to see the effective position of the driver-side vehicle in real time, a vehicle interface may be provided on the terminal of the driver through a third party application, where the vehicle interface represents the current position of the driver-side vehicle through a vehicle icon, and the position of the vehicle icon is consistent with the effective position of the vehicle. For example, when the valid position is the position D on the road T5 in the road network, the position at which the vehicle icon is displayed is also the position D on the road T5 in the road network.

To improve the bias factor lambda and the distance factor S _t Accuracy, the embodiment adopts a statistical model to offset factor lambda and distance factor S _t And updating, wherein the initial value of the statistical model can be manually set according to historical data and expert experience and is used for cold start of the system.

In one example, considering that the bias factor can meet the positioning error of most of the good open areas of the signal when λ is 20 meters, and has a certain tolerance to the signal distortion caused by the multipath effect, the initial value of the bias factor λ is set to 20. And distance factor S _t In relation to lambda, S, assuming lambda is the noise distribution in a circular region centered around the true position _t Should be greater than the diameter 2 lambda of the circle. Based on the history data, at S _t The update frequency of the effective position has a preferred effect when it differs from 2λ by 10 meters. The distance factor S of the present embodiment _t The calculation formula of the initial value is:

S _t ＝2λ+10

that is, in the present embodiment, the initial value of λ may be 20 meters, then S _t The initial value of (2) may be 50 meters.

The above is a setting manner of initial values of the bias factor and the distance factor, and it can be understood that, as the time points are different, the bias factor and the distance factor of each road change along with the different road conditions, so as to further improve the effective prediction of the actual position of the driver, the embodiment further includes: under the condition that the driver-side vehicle reaches the guest access point, acquiring an actual driving route of the driver-side vehicle; obtaining a mapping position of an observation position of a driver-side vehicle on an actual driving route of a driver, and obtaining an error data set according to a difference value between the observation position of the driver-side vehicle and the mapping position of the observation position on the actual driving route; and after the data quantity in the error data set reaches the preset quantity, updating the bias factor and the distance factor.

When the driver-side vehicle arrives at the passenger access point, the actual driving path of the driver-side vehicle is stored in the network vehicle supply platform, the embodiment requests the network vehicle supply platform to acquire the complete actual driving path of the driver-side vehicle, and compares the acquired observation position of the driver-side vehicle with the mapping position of the observation position on the actual driving path, for example, the observation position at a certain moment is O, the mapping position of the observation position O on the actual driving path is P, the difference between the position O and the position P is 1 meter, an error data set is obtained by the method, after the data amount in the error data set reaches the preset amount, the statistical data amount reaches the magnitude with statistical significance at the moment, the output of the statistical model is more stable, the real condition of the road can be reflected, and the bias factor and the distance factor are updated at the moment.

In one example, assuming that the error distribution of the observed position and the mapped position of the observed position on the actual running route approximately follows a two-dimensional gaussian distribution, the distribution of the observed position is approximately elliptical, and the observed position distribution formula is:

wherein sigma _x As the semi-major axis of the ellipse, the variance of the data in the x-direction is represented; sigma (sigma) _y As the semi-minor axis of the ellipse, the variance of the data in the y-direction is represented; s represents the scale of the ellipse, corresponding to the confidence level. The scheme takes a 95% confidence interval as a standard, namely 95% of data can be in the confidence ellipse in a statistical sense, and can solve most of service problems. Since x and y follow gaussian distribution, the degree of freedom is 2, and according to the query chi-square distribution table, the following formula can be obtained:

P(s＜5.991)＝1-0.005＝0.95

from this formula, s=5.991 is the boundary of the confidence ellipse, and is substituted into the observation position distribution formula to obtain the 95% confidence ellipse range:

meanwhile, the major axis of the ellipse can be calculated as follows:the minor axis of the ellipse is: />For the convenience of calculation and implementation of the method of this embodiment, in this embodiment, the confidence ellipse is approximated to a confidence circle, and then the radius of the confidence circle may be used as the bias factor λ, where the calculation mode is:

at the same time, the distance factor can be calculated

The bias factor lambda and the distance factor S can be derived respectively _t The calculation formula of (2) is as follows:

where n is the number of samples of the current road and t is the sample number threshold. That is, when the number of samples n of the current road is smaller than t, the bias factor λ=20, the distance factor S _t =50, whenWhen the number of samples n of the front road is greater than t, the bias factorDistance factor->

In one example, t may be 50, that is, when the amount of data in the error data set is greater than 50, the bias factor λ and the distance factor S _t And updating.

According to the method for acquiring the driver end position, the observation position of the driver end vehicle is longitudinally adjusted through the bias factor, the observation position of the driver end vehicle is reasonably projected onto the target path, the selection accuracy of the target path is improved, the projection of the observation position on the target path is transversely adjusted through the distance factor, so that the effective position is obtained, the influence of noise on the positioning of the vehicle during slow running or static state of the vehicle is reduced, the situation that the driver end vehicle position is slowly updated is avoided, and finally the effective position of the driver end vehicle is sent to the passenger terminal is avoided.
