Detailed Description

In order to enable a person skilled in the art to better understand the technical solutions in one or more embodiments of the present specification, the technical solutions in one or more embodiments of the present specification will be clearly and completely described below with reference to the drawings in one or more embodiments of the present specification, and it is obvious that the described embodiments are only some embodiments of the present specification, not all embodiments. All other embodiments, which can be made by one or more embodiments of the present disclosure without inventive effort, are intended to be within the scope of the present disclosure.

The embodiment of the parking space recommending method is as follows:

referring to fig. 1, a processing flow chart of a parking space recommending method provided by the present embodiment is shown, referring to fig. 2, a processing flow chart of a target parking lot determining process provided by the present embodiment is shown, and referring to fig. 3, a processing flow chart of a parking space recommending method applied to a vehicle navigation scene provided by the present embodiment is shown.

Referring to fig. 1, the parking space recommending method provided in the embodiment includes steps S102 to S110.

Step S102, navigation data of the vehicle navigation device is acquired.

According to the parking space recommending method, the parking space where the available parking space exists is determined by identifying and acquiring the payment data corresponding to the parking payment behaviors, the navigation data corresponding to the navigation starting behaviors and the navigation data corresponding to the navigation ending behaviors of the parking space in the historical time interval, and the parking space is recommended to the vehicle navigation equipment when the vehicle where the vehicle navigation equipment is located is about to reach the navigation destination position, so that the vehicle where the vehicle navigation equipment is led to go to the recommended parking space for parking the vehicle, the informatization of the parking space is not needed, the real-time parking space data is not needed to be acquired one by one, and the available vehicle position prediction and recommendation of the parking space are realized by depending on the payment data and the navigation data of the vehicle navigation equipment.

The vehicle navigation device in this embodiment refers to a terminal device that provides navigation for a vehicle, and may specifically be a navigation device carried by the vehicle itself, or may be a terminal device carried by a user riding the vehicle. The navigation data of the vehicle navigation device refers to data generated by the vehicle navigation device in the navigation process, and specifically, the navigation data includes a navigation starting position, a navigation destination position, a navigation path and a vehicle position of a vehicle where the vehicle navigation device is located (for example, a real-time vehicle position in the navigation process).

Step S104, determining at least one candidate parking lot meeting the parking condition when the distance between the vehicle position and the navigation destination position is detected to be smaller than a distance threshold value.

In the implementation, according to the acquired navigation destination position contained in the navigation data of the vehicle navigation device and the vehicle position of the vehicle where the vehicle navigation device is located, detecting the distance between the vehicle position and the navigation destination position, and when detecting that the distance between the vehicle position and the navigation destination position is smaller than a preset distance threshold, determining at least one candidate parking lot meeting the parking condition of the vehicle where the vehicle navigation device is located.

The parking condition of the vehicle in which the vehicle navigation apparatus is located means that a distance between a parking lot and a navigation destination position of the vehicle navigation apparatus is within a certain distance range (for example, a range of 1 km), or a travel time from the navigation destination position to the parking lot is within a certain time range (for example, a travel time is within a range of 10 minutes), because it is generally unlikely that a user will go to a far parking lot to park, but it is desirable to park nearby. Specifically, the at least one candidate parking lot meeting the parking condition comprises a parking lot corresponding to the navigation destination position, and a parking lot with a distance from the navigation destination position smaller than a preset distance threshold.

For example, in the process that the vehicle driven by the user a goes to the xx mall, the mobile terminal carried by the user a is used for navigating, the navigation destination is the xx mall, and when the distance between the real-time position of the mobile terminal carried by the user a and the xx mall is detected to be smaller than 1km, the candidate parking lots meeting the parking condition of the vehicle driven by the user a are provided with the parking lot p1 of the xx mall, and the parking lots p2, p3 and p4 with the distance between the candidate parking lot and the xx mall being within the range of 1.2 km.

And S106, acquiring historical payment data and historical navigation data of the candidate parking lot in a historical time interval.

The historical payment data in this embodiment refers to payment data of payment actions occurring in a candidate parking lot, such as collection data of merchants with the payee being an authenticated parking lot, and collection data of merchants with the payee not authenticating the category information but being determined to be a parking lot by the historical transaction characteristics.

The historical navigation data includes: the navigation initial position is positioned in the first navigation data of the candidate parking lot, and the navigation destination position is positioned in the second navigation data of the candidate parking lot.

Along the above example, on the basis of determining 4 candidate parking lots of the parking lot p1 of the xx mall itself and the parking lots p2, p3 and p4 of which the distances from the xx mall are in the range of 1.2km, if the time point of detecting that the real-time position of the mobile terminal carried by the user a and the xx mall is less than 1km is T, the collection data of each candidate parking lot within 15 minutes before the time point T is acquired respectively, the navigation start data of the start navigation behavior of each candidate parking lot within 15 minutes before the time point T is located, and the navigation destination within 15 minutes before the time point T is located in the end navigation data of the end navigation behavior of each candidate parking lot.

And step S108, determining a target parking lot recommended to the vehicle navigation device in the at least one candidate parking lot based on the historical payment data and the historical navigation data.

An optional implementation manner provided in this embodiment, based on the historical payment data and the historical navigation data, determines a target parking lot recommended to the vehicle navigation device in the at least one candidate parking lot, referring to fig. 2, specifically includes:

step S108-2, determining the number of vehicles leaving the candidate parking lot based on the historical payment data and the first navigation data.

In practical application, when a vehicle ending parking behavior of a candidate parking lot needs to pay parking fees during departure, historical payment data of the candidate parking lot are formed, meanwhile, vehicle navigation is conducted, initial navigation behavior of a vehicle navigation device with a navigation initial position located in the candidate parking lot forms first navigation data during departure, vehicles corresponding to the historical payment data and the first navigation data are inevitably repeated to a certain extent, for example, the vehicle pays during departure and navigates by taking the candidate parking lot as a navigation initial place, under the condition that departure of the same vehicle forms corresponding departure payment data and navigation data of the initial navigation behavior at the same time, in order to improve calculation accuracy of number of vehicles leaving the candidate parking lot, in an alternative implementation manner, a payment user corresponding to the historical payment data and a navigation user corresponding to the first navigation data are de-duplicated from a user dimension, and the method is specifically adopted as follows:

Performing deduplication on the payment user and the initial navigation user based on the identification of the payment user contained in the historical payment data and the identification of the initial navigation user contained in the first navigation data;

and taking the total number of the payment users after the duplication removal and the total number of the navigation users of the initial navigation users as the departure vehicle number.

The initial navigation user is determined by the following steps:

judging whether the navigation user submits an initial navigation action or not based on navigation data of the navigation user contained in the first navigation data;

if the initial navigation action is not submitted, the processing is not carried out;

if the initial navigation action is submitted, judging whether the navigation initial position of the navigation user is positioned in the parking range of the candidate parking lot;

if the vehicle is not in the parking range of the candidate parking lot, the vehicle is not processed;

if the navigation distance is within the parking range of the candidate parking lot, calculating the navigation distance between the navigation destination position and the navigation starting position of the navigation user;

judging whether the navigation distance is smaller than a preset navigation distance threshold value or not and the navigation destination position is a parking lot;

If the navigation distance is smaller than the preset navigation distance threshold value and the navigation target position is a parking lot, the navigation target position is not processed;

if the navigation distance is not smaller than a preset navigation distance threshold or the navigation target position is not a parking lot, judging whether the equipment positioning of the vehicle navigation equipment of the navigation user is positioned in the parking range of the candidate parking lot;

if the navigation user is located in the parking range of the candidate parking lot, determining the navigation user as the initial navigation user;

and if the vehicle is not in the parking range of the candidate parking lot, not processing the vehicle.

Along the above example, for the 4 candidate parking lots of parking lot p1 of xx mall and parking lot p2, parking lot p3 and parking lot p4 with the distance from xx mall within 1.2km, after acquiring the collection data of the 4 candidate parking lots within 15 minutes before the time point T and the initial navigation data of the initial navigation behavior of the candidate parking lot, according to the mobile phone number of the payment user contained in the collection data and the mobile phone number of the navigation user contained in the initial navigation data, carrying out de-duplication on the payment user and the navigation user with the same mobile phone number, wherein the total number of the payment user and the navigation user after de-duplication is the total number of the off-site users of the candidate parking lots, namely the off-site vehicle number of the off-site vehicles.

And step S108-4, determining the number of approaching vehicles of the candidate parking lot based on the second navigation data.

In order to improve the accuracy of calculation of the number of approaching vehicles in the candidate parking lot, in an optional implementation manner provided in this embodiment, the duplicate removal is performed on the end navigation user corresponding to the end navigation data included in the second navigation data from the user dimension, which is specifically implemented in the following manner:

1) Determining a first end navigation user corresponding to end navigation data of which the submitted end navigation action is contained in the second navigation data and the navigation destination position is located in the range of the candidate parking lot;

2) Determining a submitting ending navigation action contained in the second navigation data and positioning a second ending navigation user corresponding to the ending navigation data of the candidate parking lot by equipment of the vehicle navigation equipment;

3) Performing de-duplication on the first ending navigation user and the second ending navigation user based on the identity of the first ending navigation user and the second ending navigation user;

4) And taking the total number of the end navigation users of the first end navigation user and the second end navigation user after the duplication removal as the number of the approaching vehicles.

Along the above example, for 4 candidate parking lots of the parking lot p1 of the xx market itself and the parking lots p2, p3 and p4 with the distance from the xx market within the range of 1.2km, after obtaining the end navigation data of the end navigation behavior of the candidate parking lots, in 15 minutes before the time point T, of each of the 4 candidate parking lots, firstly determining that the end navigation action is submitted by the vehicle navigation device in the end navigation data and the navigation destination is the end navigation user of the part of the candidate parking lots, secondly determining that the end navigation action is submitted by the vehicle navigation device in the end navigation data and the real-time positioning of the vehicle navigation device is the end navigation user of the other part of the candidate parking lots, then according to the mobile phone numbers of the two end navigation users, removing the weight of the end navigation users with the same mobile phone number, and finally taking the end navigation users of the two end navigation users after removing the weight as the approach vehicle number of the approach vehicles of the candidate parking lots.

And S108-6, calculating the available number of vehicles of the candidate parking lot according to the number of the leaving vehicles and the number of the entering vehicles.

In order to avoid the situation that the number of vehicles leaving the parking space is smaller than the number of vehicles entering the parking space, in an alternative implementation manner provided in the embodiment, the number of available vehicles of the candidate parking space is calculated by adopting the following manner:

Calculating a vehicle difference value obtained by subtracting the approach vehicle number from the departure vehicle number;

judging whether the vehicle difference is greater than or equal to 0;

if yes, indicating that the number of the vehicles leaving the candidate parking lot is larger than or equal to the number of vehicles entering the candidate parking lot, and taking the vehicle difference value as the available number of vehicles in the candidate parking lot;

and if not, indicating that the number of the vehicles leaving the candidate parking lot is less than or equal to the number of vehicles entering the candidate parking lot, and determining the available number of vehicles in the candidate parking lot as 0.

In addition, in the specific implementation, in order to further improve the validity of the available number of digits of the candidate parking lot, the alternative implementation of the embodiment corrects the available number of digits of the candidate parking lot so that the corrected available number of digits can conform to the actual parking space allowance of the candidate parking lot, specifically, the first alternative implementation provided by the embodiment corrects the upper limit of the available number of digits of the candidate parking lot, and the second alternative implementation corrects the lower limit of the available number of digits of the candidate parking lot.

Specifically, a first alternative embodiment for correcting the upper limit of the available number of vehicles in the candidate parking lot includes:

Obtaining the reference number of vehicles of the candidate parking lot; the reference parking space data refer to the maximum number of vehicles in the candidate parking lot;

judging whether the available vehicle number is larger than the reference vehicle number or not;

if yes, indicating that the calculated available vehicle number exceeds the maximum vehicle number of the candidate parking lot, and correcting the available vehicle number to be equal to the reference vehicle number;

if not, indicating that the calculated available vehicle position number does not exceed the maximum vehicle position number of the candidate parking lot, and keeping the available vehicle position number of the candidate parking lot unchanged.

A second alternative embodiment for correcting the lower limit of the number of available vehicles in the candidate parking lot includes:

acquiring second historical navigation data of the candidate parking lot in a second historical time interval;

judging whether a parking failure user meeting a preset user number exists in navigation users corresponding to navigation data contained in the second historical navigation data;

if yes, correcting the available number of bits to be 0;

if not, keeping the available number of vehicles in the candidate parking lot unchanged.

The parking failure user is determined by the following steps:

judging whether the navigation user initiates a navigation starting action within a preset time range after submitting the navigation ending action;

If yes, determining the navigation user as the parking failure user;

if not, the processing is not carried out.

Or alternatively, the process may be performed,

if the device positioning of the vehicle navigation device of the navigation user is located within the parking range of the candidate parking lot, whether there is an operation of changing the navigation destination position;

if yes, determining the navigation user as the parking failure user;

if not, the processing is not carried out.

Taking 4 candidate parking lots of the parking lot p1 of the xx market itself and the parking lots p2, p3 and p4 with the distance within 1.2km from the xx market as an example, taking any one of the 4 candidate parking lots as an example, the maximum number of vehicles of the candidate parking lot is 300, judging whether the calculated number of vehicles of the candidate parking lot is greater than 300, if so, correcting the number of vehicles of the candidate parking lot to 300;

further, it is judged whether the number of the failed parking users whose parking has failed in 3 minutes between the time points T is greater than N, if the number of the failed parking users whose parking has failed in 3 minutes between the time points T is greater than N, it is indicated that the failed parking has frequently occurred recently in the candidate parking lot, it is highly likely that the parking space of the candidate parking lot has been already stopped, in which case the available number of vehicles in the candidate parking lot is corrected to 0.

Step S108-8, based on the available number of vehicles, determining the target parking lot recommended to the vehicle navigation device in the at least one candidate parking lot.

As described above, at least one candidate parking lot satisfying the parking condition includes a parking lot corresponding to the navigation destination location, and a parking lot having a distance from the navigation destination location smaller than a preset distance threshold, based on which, in order to promote the recommendation validity of the target parking lot recommended to the vehicle navigation device, promote the recommendation satisfaction of the user, in an alternative implementation provided in this embodiment, based on the number of available vehicles, the target parking lot recommended to the vehicle navigation device in the at least one candidate parking lot is determined, specifically implemented as follows:

judging whether the available number of vehicles in the parking lot corresponding to the navigation destination position is larger than 0;

if yes, taking the parking lot corresponding to the navigation target position as the target parking lot.

If not, selecting a first candidate parking lot with the minimum distance from the navigation destination position aiming at the parking lot with the distance from the navigation destination position smaller than a preset distance threshold value;

and selecting a second candidate parking lot with the largest available vehicle number for the parking lot with the distance from the navigation destination position smaller than a preset distance threshold, and taking the first candidate parking lot and the second candidate parking lot as the target parking lot.

In addition, on the basis of considering two dimensions of distance and available vehicle positions, in order to promote the recommendation effectiveness of the target parking lot recommended to the vehicle navigation device, a parking lot with moderate distance and higher parking success rate is recommended to the user, so as to promote the recommendation satisfaction of the user, and when the available vehicle position of the parking lot corresponding to the navigation destination position is less than or equal to 0, namely: and under the condition that the parking lot corresponding to the navigation destination position cannot park, aiming at the parking lot with the distance from the navigation destination position being smaller than a preset distance threshold, calculating the recommended priority of the parking lot according to the distance from the parking lot to the navigation destination position and the corresponding distance weight, and selecting the parking lot with the highest recommended priority as the target parking lot.

Taking still the example of 4 candidate parking lots of the parking lot p1 of the xx mall and the parking lot p2, the parking lot p3 and the parking lot p4 with the distance within 1.2km from the xx mall, if the available number of vehicles in the parking lot p1 of the xx mall is greater than 0, namely: when parking lot p1 is available for parking, parking lot p1 is set as a recommended parking lot for user a;

If the available number of digits of park p1 of xx mall itself is less than or 0, namely: when the parking lot p1 is already parked and cannot continue parking, selecting the parking lot closest to the xx mall among the parking lots p2, p3 and p4 as the parking lot recommended to the user A; alternatively, if the available number of digits of parking lot p1 of xx mall itself is less than or 0, namely: under the condition that the parking lot p1 is stopped fully and cannot continue parking, according to the distances between the parking lot p2, the parking lot p3 and the parking lot p4 and xx markets, the available number of vehicles of the parking lot p2, the parking lot p3 and the parking lot p4, the distance weight coefficient corresponding to the distances and the parking space weight coefficient corresponding to the available number of vehicles calculate the weighted sum of the parking lot p2, the parking lot p3 and the parking lot p4, and finally the parking space with the largest weighted sum is selected to be recommended to the user A.

And step S110, generating recommendation information of the target parking lot and recommending the recommendation information to the vehicle navigation equipment.

In the implementation, the recommended information of the target parking lot is generated, and the recommended information is sent to the vehicle navigation equipment to recommend the target parking lot, so that a user to which the vehicle navigation equipment belongs can park the vehicle in an empty space of the target parking lot.

In order to facilitate a user to park a vehicle to a recommended target parking lot directly, in an optional implementation manner provided in this embodiment, a secondary navigation control is set in the recommendation information to remind and guide the user to go to the recommended target parking lot, specifically, after recommendation information of the target parking lot is generated and recommended to the vehicle navigation device, whether the secondary navigation control contained in the recommendation information is triggered is detected, when the secondary navigation control contained in the recommendation information is detected to be triggered, a secondary navigation path is generated based on a vehicle position of the vehicle navigation device and position information of the target parking lot, a navigation path contained in navigation data of the vehicle navigation device is updated based on the secondary navigation path, and a navigation update prompt is sent to the vehicle navigation device.

For example, in the process that the vehicle driven by the user a goes to the xx mall, the determined candidate parking lot includes a parking lot p1 of the xx mall and 4 of parking lots p2, p3 and p4 with distances from the xx mall within a range of 1.2km, the finally determined parking space recommended to the user a is the parking lot p3, voice reminding information of the parking lot p3 and page information of a 'one-key navigation' button guiding the user to go to the parking lot p3 are generated, after the voice reminding information and the page information are sent to the mobile terminal of the user a, the page information is played at the mobile terminal of the user a, the 'one-key navigation' button is rendered and displayed on the mobile terminal of the user a, if the 'one-key navigation' button displayed by the mobile terminal is detected to be triggered by the user, a new navigation path from the current position of the user a to the parking lot p3 is generated, the original navigation path is updated on the basis of the new navigation path, and the voice reminding information with the updated navigation path is played at the mobile terminal of the user a.

The following further describes the parking space recommending method provided in this embodiment by taking an application of the parking space recommending method provided in this embodiment to a vehicle navigation scene as an example, and referring to fig. 3, the parking space recommending method applied to the vehicle navigation scene specifically includes steps S302 to S328.

Step S318, judging whether a parking failure user meeting the preset user number exists in the navigation users corresponding to the navigation data contained in the second historical navigation data;

if yes, go to step S320 to step S328;

Step S320, the available number of vehicles in the candidate parking lot is corrected to 0.

Step S322 determines a target parking lot recommended to the vehicle navigation apparatus among the at least one candidate parking lot based on the number of available vehicles.

Step S324, generating recommendation information of the target parking lot and recommending the recommendation information to the vehicle navigation device.

In summary, according to the parking space recommending method provided by the embodiment, the distance between the vehicle navigation device and the navigation destination position is detected by acquiring the navigation data of the vehicle navigation device, at least one candidate parking lot meeting the parking condition is determined according to the detection result, the parking lot with the available parking space is determined by identifying and acquiring the payment data corresponding to the parking payment behavior, the navigation data corresponding to the starting navigation behavior and the navigation data corresponding to the ending navigation behavior of the parking lot in the historical time interval, and the available parking space is recommended to the vehicle navigation device before the vehicle where the vehicle navigation device is located reaches the navigation destination position, so that the available parking space prediction and recommendation of the parking lot are realized through the payment data and the navigation data of the vehicle navigation device, the recommendation effectiveness of the target parking lot recommended to the vehicle navigation device is improved, and the recommendation satisfaction of a user is improved.

The embodiment of the parking space prediction method for the parking lot provided by the specification is as follows:

referring to fig. 4, the parking space prediction method for the parking lot provided in the present embodiment includes steps S402 to S410.

Step S402, obtaining payment data of a parking lot in a first time interval, first navigation data of a navigation starting position in the parking lot, and second navigation data of a navigation destination position in the parking lot.

According to the parking space recommending method, the parking space with the available parking space is determined by identifying and acquiring the payment data corresponding to the parking payment behaviors, the navigation data corresponding to the starting navigation behaviors and the navigation data corresponding to the ending navigation behaviors of the parking space in the historical time interval, and the available vehicle number of the parking space is corrected by identifying the parking space capacity and the parking failure behaviors, so that the parking space recommending method is used as a basis for recommending the parking space to a user, does not need to rely on informatization of the parking space, does not need to access the parking space one by one to acquire real-time parking space data, but relies on the payment data and the navigation data of the vehicle navigation equipment to realize available vehicle position predication and recommendation of the parking space, and is low in cost and high in applicability.

The payment data in this embodiment refers to payment data of a payment action occurring in a parking lot, such as collection data of a merchant whose payee is an authenticated parking lot, and collection data of a merchant whose payee does not authenticate category information but is determined to be a parking lot by a historical transaction feature.

The first navigation data and the second navigation data refer to navigation data of a vehicle navigation device; the vehicle navigation device may be a navigation device carried by the vehicle itself, or may be a terminal device carried by a user riding the vehicle; the navigation data of the vehicle navigation device refers to data generated by the vehicle navigation device during navigation, and specifically, the navigation data includes a navigation start position, a navigation destination position, a navigation path, and a vehicle position of a vehicle in which the vehicle navigation device is located (for example, a real-time vehicle position during navigation).

For example, collection data of parking lot p1 in a 15-minute period of xx:00:xx-xx:15:xx, which is a period in which navigation is started from the start navigation data of the start navigation behavior of parking lot p1, and end navigation data of the end navigation behavior of parking lot p1, which is a navigation destination, are acquired.

Step S404, determining the number of vehicles leaving the parking lot based on the payment data and the first navigation data.

In practical application, a vehicle ending parking behavior in a parking lot needs to pay parking fees when leaving a parking lot, so as to form payment data of the parking lot, meanwhile, vehicle navigation is performed, initial navigation behavior of a vehicle navigation device with a navigation initial position located in the parking lot forms first navigation data when leaving the parking lot, and vehicles corresponding to the two data of the payment data and the first navigation data are inevitably repeated to a certain extent, for example, the vehicle is paid when leaving the parking lot and navigates by taking the parking lot as a navigation initial place, in this case, the leaving of the same vehicle simultaneously forms corresponding leaving payment data and navigation data of the initial navigation behavior, in an alternative embodiment provided by the embodiment, in order to improve calculation accuracy of leaving vehicle number of the parking lot, a payment user corresponding to the payment data and a navigation user corresponding to the first navigation data are deduplicated from a user dimension, and the method is specifically implemented as follows:

Performing deduplication on the payment user and the initial navigation user based on the identification of the payment user contained in the payment data and the identification of the initial navigation user contained in the first navigation data;

and taking the total number of the payment users after the duplication removal and the initial navigation users as the number of the departure vehicles.

The initial navigation user is determined by the following steps:

if yes, judging whether the navigation initial position of the navigation user is positioned in the parking range of the parking lot;

if yes, calculating the navigation distance between the navigation destination position and the navigation initial position of the navigation user;

if not, judging whether the equipment positioning of the vehicle navigation equipment of the navigation user is positioned in the parking range of the parking lot;

if yes, determining the navigation user as the initial navigation user.

According to the above example, based on acquiring the collection data and the initial navigation data of the parking lot p1 in the 15-minute time period, the mobile phone number of the payment user and the mobile phone number of the navigation user contained in the initial navigation data are used for carrying out duplication removal on the payment user and the navigation user with the same mobile phone number, and the total number of users of the payment user and the navigation user after duplication removal is the total number of users of the departure user of the parking lot p1, namely the number of vehicles of the departure vehicle.

Step S406, determining the number of approaching vehicles in the parking lot based on the second navigation data.

In order to improve the accuracy of calculation of the number of approaching vehicles in the parking lot, in an optional implementation manner provided in this embodiment, the deduplication is performed on the ending navigation user corresponding to the ending navigation data included in the second navigation data from the user dimension, and specifically, the following manner is adopted:

1) Determining a first end navigation user corresponding to end navigation data of which the submitted end navigation action and the navigation destination position are positioned in the range of the parking lot, wherein the first end navigation user is included in the second navigation data;

2) Determining a submitting ending navigation action contained in the second navigation data and positioning a second ending navigation user corresponding to ending navigation data of the parking lot by equipment of the vehicle navigation equipment;

According to the method, on the basis of acquiring the ending navigation data of the parking lot p1 in a 15-minute time period, firstly determining that the ending navigation user submits ending navigation actions through the vehicle navigation equipment in the ending navigation data and the navigation destination ends the navigation user in the part of the parking lot p1, secondly determining that the ending navigation user submits the ending navigation actions through the vehicle navigation equipment in the ending navigation data and the real-time positioning of the vehicle navigation equipment in the other part of the parking lot p1, then performing duplication elimination on the ending navigation user with the same mobile phone number according to the mobile phone number of the two ending navigation users, and finally taking the ending navigation user number of the two ending navigation users after duplication elimination as the approach vehicle number of the approach vehicle of the parking lot p 1.

Step S408, calculating the available number of vehicles in the parking lot according to the number of vehicles leaving the parking lot and the number of vehicles entering the parking lot.

In order to avoid the situation that the number of vehicles leaving the parking lot is smaller than the number of vehicles entering the parking lot, and in an alternative implementation manner provided in the embodiment, the number of available vehicles in the parking lot is calculated by adopting the following manner:

judging whether the vehicle difference is greater than or equal to 0;

if yes, indicating that the number of vehicles leaving the parking lot is greater than or equal to the number of vehicles entering the parking lot, and taking the vehicle difference value as the available number of vehicles in the parking lot;

if not, indicating that the number of the off-road vehicles in the parking lot is less than or equal to the number of the on-road vehicles, and determining the available number of vehicles in the parking lot to be 0.

And step S410, correcting the available number of vehicles according to the reference number of vehicles of the parking lot and the third navigation data in the second time interval.

In particular, in order to further improve the validity of the available number of digits in the parking lot, the optional implementation of this embodiment corrects the available number of digits in the parking lot, so that the corrected available number of digits can conform to the actual remaining space of the parking lot, and specifically, the first optional implementation provided in this embodiment corrects the upper limit and the lower limit of the available number of digits in the parking lot, including:

Obtaining a reference number of vehicles in a parking lot;

if not, indicating that the calculated available vehicle number does not exceed the maximum vehicle number of the parking lot, and keeping the available vehicle number of the parking lot unchanged;

if yes, indicating that the calculated available vehicle number exceeds the maximum vehicle number of the parking lot, and correcting the available vehicle number to be equal to the reference vehicle number;

judging whether a parking failure user meeting a preset user number exists in navigation users corresponding to the navigation data contained in the third navigation data;

if yes, correcting the available number of vehicles in the parking lot to be 0;

if not, keeping the available number of vehicles in the parking lot unchanged.

The parking failure user is determined by the following steps:

if yes, determining the navigation user as the parking failure user;

or alternatively, the process may be performed,

if the equipment positioning of the vehicle navigation equipment of the navigation user is positioned in the parking range of the parking lot, whether an operation of changing the navigation destination position exists or not;

if yes, determining the navigation user as the parking failure user.

Taking the parking lot p1 as an example, the maximum number of vehicles in the parking lot p1 is 300, judging whether the calculated number of available vehicles in the parking lot p1 is greater than the maximum number of vehicles in the parking lot p1 by 300, and if so, correcting the available vehicles in the parking lot p1 to 300; further, it is judged whether the number of failed users in which the failed parking occurs in the 3-minute period of xx:21:xx-xx:15:xx of the parking lot p1 is greater than N, if the number of failed users in which the failed parking occurs in the 3-minute period of the parking lot p1 is greater than N, it is indicated that the failed parking of the parking lot p1 occurs frequently in the near future, it is highly likely that the parking space of the parking lot p1 has been already full, and in this case, the available number of vehicles of the parking lot p1 is corrected to 0.

It should be noted that, in this embodiment, after the available number of digits of the parking lot is calculated and modified, the calculation result is stored for later use and calling, specifically, by establishing a mapping relationship between the available number of digits of the parking lot and the first time interval, and storing the available number of digits and the time information of the first time interval in a storage space.

On the basis, under the condition that a parking space inquiry request submitted by the vehicle navigation equipment is received, determining a target parking lot corresponding to a navigation destination position of the vehicle navigation equipment; reading the available number of vehicles of the target parking lot in a first time interval corresponding to the current time from the storage space; judging whether the available number of vehicles is 0;

If yes, generating recommendation information of the target parking lot and recommending the recommendation information to the vehicle navigation equipment;

if not, the following alternative embodiments provided in this embodiment are adopted to make parking lot recommendation:

1) Determining a candidate parking lot with the distance from the navigation destination position smaller than a preset distance threshold value;

2) Reading available vehicle numbers of the candidate parking lot in a first time interval corresponding to the current time from the storage space;

3) Calculating the recommended priority of the candidate parking lot according to the distance between the candidate parking lot and the navigation destination position and the corresponding distance weight, and the available number of vehicles and the corresponding number of parking spaces of the candidate parking lot;

4) And selecting the candidate parking lot with the highest recommendation priority as a recommendation parking lot, generating recommendation information of the recommendation parking lot and recommending the recommendation information to the vehicle navigation equipment.

In order to facilitate a user to park a vehicle to a recommended parking lot directly, in an optional implementation manner provided in this embodiment, a secondary navigation control is set in the recommended information to remind and guide the user to go to the recommended parking lot, specifically, when the secondary navigation control included in the recommended information is detected to be triggered, a secondary navigation path is generated based on the vehicle position of the vehicle navigation device and the position information of the target parking lot, the navigation path included in the navigation data of the vehicle navigation device is updated based on the secondary navigation path, and a navigation update prompt is sent to the vehicle navigation device.

For example, in the process that the vehicle driven by the user a goes to the xx mall, the available number of vehicles in the parking lot p1 of the xx mall is 0, the determined candidate parking lots are 3 candidate parking lots of the parking lots p2, p3 and p4 in the surrounding 1.2km, after calculating the weighted sum of the distance and the distance weight and the available number of vehicles and the number of vehicles weight, the parking lot recommended to the user a is determined to be the parking lot p3, voice reminding information of the parking lot p3 and page information of a one-key navigation button guiding the user to go to the parking lot p3 are generated, the voice reminding information and the page information are transmitted to the mobile terminal of the user a, the page information is played at the mobile terminal of the user a, the one-key navigation button is rendered and displayed based on the mobile terminal of the user a, if the one-key navigation button displayed by the user a is detected to be triggered by the user, a new navigation path going to the parking lot p3 from the current position of the user a is generated, the original navigation path is updated based on the new navigation path, and the updated voice reminding navigation path is played at the mobile terminal of the user a.

The foregoing describes specific embodiments of the present disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

In the 30 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.

The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
