In an embodiment of the invention, the user comprises a driver or a passenger.
In the embodiment of the invention, after a vehicle to be parked is driven to a parking lot, a user opens an application program for autonomous parking on a held mobile terminal and clicks a 'one-key parking' key so as to send parking request information to a central cloud server. When a user downloads an application program for autonomous parking for the first time, personal information of the user is registered and vehicle information of the user is bound. The central cloud server stores the vehicle identification code, and when the user uses the application program for autonomous parking again and clicks the one-touch parking key, the central cloud server sends parking request information including the vehicle identification code to the central cloud server.
In the embodiment of the invention, the vehicle identification code can uniquely identify one vehicle.
In the embodiment of the invention, the vehicle-mounted equipment comprises vehicle communication equipment and a vehicle decision center. The vehicle decision center is used for controlling the vehicle to move and calculating the minimum safe distance.
In the embodiment of the invention, the central cloud server identifies the vehicle identified by the vehicle identification code according to the vehicle identification code, and sends a vehicle information query request to the vehicle communication equipment of the vehicle to obtain the vehicle information of the vehicle.
In the embodiment of the invention, the vehicle communication equipment sends the vehicle information to the central cloud server according to the first time period, so that the central cloud server can acquire the vehicle information of the vehicle in real time.
In the embodiment of the invention, the vehicle information comprises the current position, the vehicle size, the vehicle speed and the heading angle.
In the embodiment of the invention, the geomagnetic equipment sends the parking space information to the central cloud server according to the second time period, so that the central cloud server can acquire the parking space information in real time.
In the embodiment of the invention, one geomagnetic device corresponds to one parking space information.
In the embodiment of the invention, the parking space information comprises the current state and the parking space size. Wherein the current state includes idle, occupied or reserved. As shown in fig. 2, one geomagnetic device 4 is provided for each parking space in the parking lot. The geomagnetic device 4 has an NB-IoT function. The geomagnetic sensor can monitor the state of the parking space in real time, and report the monitored state of the parking space to the central cloud server through the NB-IoT function according to the second time period, so that the state of the parking space is reported to the central cloud server in real time, and the central cloud server updates the current state of the parking space in the parking lot database according to the received state of the parking space.
In the embodiment of the invention, the central cloud server inquires whether the current state comprises an idle parking space or not according to the current state, and if so, the central cloud server indicates that the idle parking space exists; continuing to execute step 207; if not, indicating that no free parking space exists, and continuing to execute the step 206.
In the embodiment of the invention, as no free parking space is available for the vehicle to be parked to park in the parking lot, the central cloud server is required to send the waiting message to the mobile terminal. As an alternative, the waiting message is "no free space currently, please wait. ".
In the embodiment of the invention, after receiving the waiting message sent by the central cloud server, the mobile terminal displays the waiting message to remind the user of waiting for the parking space, and the user can continue to wait, and step 201 is executed, and the mobile terminal sends parking request information to the central cloud server until a matched parking space exists.
And step 207, generating parking point position information by the central cloud server.
In the embodiment of the present invention, as shown in fig. 2, each parking space includes a parking spot, such as the parking spot A, B, C, D, E or F, which is disposed on the aisle while being adjacent to the parking space.
In the embodiment of the invention, the parking spot position information is used for indicating the position of the parking spot and is stored in the central cloud server. A parking spot is a location where a vehicle can achieve automatic parking. The parking spot location information includes the number of the parking spot.
In the embodiment of the invention, the number of the free parking spaces is one or more. When the number of the idle parking spaces is one, determining the idle parking spaces as target parking spaces; when the quantity of idle parking stall is a plurality of, target parking stall need be sieved out from a plurality of idle parking stalls to central cloud server.
In the embodiment of the invention, the method for screening out the target parking space from the plurality of free parking spaces by the central cloud server can comprise a plurality of modes. Three possible embodiments are illustrated here: in the first mode, the central cloud server randomly screens out one free parking space from all the free parking spaces, and determines the free parking space as a target parking space; in the second mode, the central cloud server screens parking spaces with parking space sizes larger than or equal to the size of the vehicle from all the idle parking spaces, and determines the screened parking spaces as target parking spaces. If a plurality of screened parking spaces exist, the parking space corresponding to the smallest parking space size can be determined as a target parking space; in the third mode, the central cloud server screens out an idle parking space closest to the current position of the vehicle from all the idle parking spaces, and determines the idle parking space as a target parking space. The above three ways are only examples and are not limited to the above three ways.
It should be noted that the parking spot position information may also be generated by other manners, and the embodiment of the present invention is only exemplary and is not limited thereto.
And step 208, the central cloud server sends the parking point position information to the mobile terminal.
In the embodiment of the invention, the central cloud server sends the number of the target parking space in the parking space position information to the mobile terminal, so that the mobile terminal can display the number of the target parking space, and a user is informed of the parking space number of the target parking space to be parked.
And step 209, the central cloud server receives a reservation instruction input by the user through the mobile terminal.
In the embodiment of the invention, the mobile terminal displays the number of the target parking space and simultaneously inquires whether the user reserves or not, and the user can click a reservation button or a non-reservation button through the mobile terminal. And if the user clicks the 'no reservation' button, the user is indicated to give up the autonomous parking.
In the embodiment of the invention, if the user clicks the 'reservation' instruction, the user is indicated to need to park autonomously. The mobile terminal sends the reservation instruction to the center cloud server, and the center cloud server responds to the reservation instruction and updates the parking space state information of the parking space from idle to reserved.
And step 211, the central cloud server matches a target edge cloud server from the plurality of edge cloud servers according to the vehicle information.
