Wherein, the quantity of parking area serial number is a plurality of. The AVP service platform or the cloud platform writes a vehicle-field matching table generated aiming at the license plate number into an XML (Extensible Markup Language) file for caching, and obtains a preset vehicle-field matching table of the vehicle so as to call data. XML data is stored in a plain text format, so that the XML data is easier to read, more convenient to record and debug, and the data sharing among different systems and different programs is simpler. It should be noted that, for each registered license plate number, a corresponding vehicle-field matching table is cached in the AVP service platform or the cloud platform. The corresponding vehicle-field matching table is cached aiming at each registered license plate number, so that the data of the vehicle-field matching table can be conveniently and quickly called in the parking space allocation process, and the response speed of parking space allocation is improved.
Specifically, a first parking lot set matched with the vehicle is obtained in a preset vehicle-field matching table according to the parking space allocation request, and the method comprises steps 1021-1024:
and step 1021, acquiring a second parking lot set matched with the vehicle from a preset vehicle-field matching table according to the license plate number.
In this embodiment, the AVP service platform or the cloud platform obtains, according to the license plate number, a second parking lot set matched with the license plate number from a preset vehicle-to-field matching table, that is, obtains a set of all parking lot numbers in the vehicle-to-field matching table of the license plate number. Preferably, the corresponding number of the parking lot within the preset threshold distance from the current position or destination of the vehicle can be acquired, and the preferable scheme can reduce the calculation amount and further improve the response speed of the parking space allocation. The vehicle-field matching table is generated based on the matching relation between the vehicle AVP capability and the AVP service level of the parking lot, so that the parking lots in the second parking lot set acquired from the vehicle-field matching table can meet the AVP capability of the vehicle, and the safety of autonomous parking is ensured.

And step 1024, screening out parking lots supporting AVP service provision under the weather and illumination intensity at the current time from the second parking lot set to obtain a first parking lot set.
In this embodiment, the AVP service platform or the cloud platform compares the queried weather at the current time and the estimated illumination intensity with the weather and illumination intensity threshold values supported by the field terminals in the parking lot information of each parking lot in the second parking lot set, and screens out the parking lots supporting the AVP service at the current time under the weather and illumination intensity from the second parking lot set, so as to obtain the first parking lot set. And screening out the first parking lot set from the second parking lot set according to the current real-time weather and illumination intensity conditions of the parking space allocation request, so that the parking fields in the first parking lot set can further ensure the safety of autonomous parking.
And 103, acquiring available parking lots in the first parking lot set and the priority sorting set of the parking lots, and sending the available parking lots and the priority sorting set of the parking lots to a user for selection.
Specifically, the priority ranking set of available parking lots and parking lots in the first parking lot set is obtained and sent to the user for selection, which includes steps 1031 and 1036:
and step 1031, inquiring parking space states of all parking lots in the first parking lot set, and screening out parking lots with free parking spaces to obtain a third parking lot set, wherein the third parking lot set comprises a mapping relation between a parking lot number and a free parking space number.
In this embodiment, the parking space states in the parking space information of the parking spaces in the first parking lot set are queried, the parking lots with idle parking spaces are screened out, and a third parking lot set is obtained, where the third parking lot set includes a mapping relationship between a parking lot number and a parking space number of an idle parking space. The number of the obtained parking lot numbers included in the third parking lot set may be multiple, and the number of the free parking space numbers corresponding to each parking lot number may be multiple.
And 1032, acquiring the time lengths from the current positions of the vehicles to the getting-off point positions of the drivers of all the parking lots in the third parking lot set respectively, and sequencing all the parking lots in the third parking lot set according to the sequence of the time lengths from small to large to obtain a fourth parking lot sequencing set.
In this embodiment, the parking lot with the shortest time length from the current position of the vehicle to the driver's exit point position of the parking lot is the parking lot with the highest priority. And the fourth parking lot sequencing set is obtained by sequencing the parking lots and the free parking spaces thereof in the third parking lot set according to the priority from small to large according to the time length from the current position of the vehicle to the getting-off point position of the driver in the parking lot. Wherein the number of parking lots in the fourth parking lot sort set is the same as the number of parking lots in the third parking lot set.
And 1033, calculating paths from the getting-off point position of the driver of each parking lot in the fourth parking lot sequencing set to all parking points of the idle parking spaces in the parking lot.
In this embodiment, the path from the get-off point position of the driver in each parking lot to the parking points in all the vacant parking spaces in the parking lot is the driving path for autonomous passenger-assisted parking.

And 1035, sequencing the paths according to the sequence of the influence degrees of the obstacles from small to large to obtain the priority sequence of the free parking spaces corresponding to the paths.
In this embodiment, the determination rule of the degree of influence by the obstacle may be preset on the AVP platform or the cloud platform, for example, the degree of influence by the obstacle may be evaluated according to the number of vehicles to be autonomously parked by the agent at the field end, and the degree of influence by the obstacle is higher for a plurality of vehicles waiting to be parked on the route compared with a vehicle without waiting. Step 1035 is to complete the priority ranking according to the degree of influence of the obstacle on each free parking space of each parking lot in the fourth parking lot ranking set.
