The target area range refers to an area range under the jurisdiction of the current road end server, that is, all the second terminals in the jurisdiction area range send the parking space correlation information to the current road end server. The meaning of the parking space related information sent by the at least one second terminal is that when only one second terminal exists in the target area, the parking space related information is sent by the second terminal, and when a plurality of second terminals exist in the target area, the parking space related information may refer to a set, or may refer to parking space related information sent by each of the plurality of second terminals, so that the flow chart is not limited.

It should be noted that how the road end server integrates and summarizes the parking space correlation information from the second terminal in the present application is not limited to the scheme of the above embodiment, and there is no limitation on the target area parking space model diagram established by the road end server; the effect of way end server is to the parking stall associated information of all second terminals in its target area within range carry out preliminary collection and gather, consequently, the quantity of way end server can be a plurality of, so, can prevent that all second terminals in all area within ranges from directly sending data to high in the clouds server, causes the high in the clouds to need to handle magnanimity real-time data, leads to the poor problem of timeliness.
The above steps S201 to S211 describe the collection process of the parking space information, and the following description continues to describe the sharing process of the parking space information, where the sharing process of the parking space information is mainly executed by the parking space sharing server. The name of the terminal is hereinafter redefined as the first terminal due to the state switching of the terminal. It should be noted that the first terminal and the second terminal may refer to the same terminal in different states, or may refer to different terminals in different states, that is, the terminals may only participate in the collecting process of the parking space information, may only participate in the sharing process of the parking space information, or may both participate in the collecting process of the parking space information and the sharing process of the parking space information at different times.

In the embodiment of the present application, the first terminal is also mainly referred to as a vehicle. The parking space finding state means that when the first terminal user inputs a navigation destination through a user interface, voice or the like or searches a nearby parking lot, it indicates that there is a parking demand at this time, and thus the first terminal determines that the first terminal is in the parking space finding state. The user interface includes an interface of an in-vehicle display device, such as a center control display screen. When information input by a user through a user interface or voice is recognized as information related to a navigation destination or a nearby parking lot in the background, the first terminal sends a parking space recommendation request to the parking space sharing server.
S215: the parking space sharing server receives a parking space recommendation request sent by the first terminal, wherein the parking space recommendation request comprises target position information in a target area range.
In this embodiment of the application, the parking space recommendation request sent by the first terminal includes target location information, and the target location information includes the aforementioned navigation destination location or parking lot location.

Subsequently, by adding a new road end server, the regional parking space state identification atlas can be enriched continuously, so that parking space information in a larger region is covered.
In the embodiment of the application, after receiving a parking space recommendation request of a first terminal, a parking space sharing server finds out a target area parking space state identification map corresponding to a target area range from an area parking space state identification map set.
In an optional implementation manner, the parking space recommendation request sent by the first terminal only includes the target location information, but does not include the target area range, and the parking space sharing server first determines the corresponding target area range according to the target location information, and then finds out the target area parking space state identification map corresponding to the target area range from the area parking space state identification map set.

S223: and the first terminal receives at least one candidate parking space returned by the parking space sharing server.
In the embodiment of the application, the first parking space state mainly refers to an available state, and the parking space sharing server takes a parking space of which the current parking space state near the target position information is the available state as a candidate parking space from the target area parking space state identification diagram; if at least one candidate parking space exists, returning to the first terminal; and if the candidate parking spaces do not exist, returning the information of the unavailable parking spaces to the first terminal to finish the sharing of the parking space information.
In the embodiment of the application, the parking space sharing server can provide parking space information sharing service for the first terminal and can also provide parking space path navigation service.
In an optional implementation manner, after step S221, the following steps are further included: the parking space sharing server judges whether selection information aiming at a first target parking space in at least one candidate parking space sent by a first terminal is received within first preset time;
if the selection information aiming at a first target parking space in at least one candidate parking space sent by a first terminal is received within a first preset time, a parking space sharing server plans a first target path by taking the first target parking space as a terminal point and returns the first target path to the first terminal; or if the selection information aiming at the first target parking space in the at least one candidate parking space sent by the first terminal is not received within the first preset time, the parking space sharing server determines a second target parking space from the at least one candidate parking space; and planning a second target path by taking the second target parking space as a terminal, and returning the second target path to the first terminal.
Specifically, the parking space sharing server starts timing from the moment of returning at least one candidate parking space to the first terminal, and if the selection information of the first terminal for a first target parking space in the at least one candidate parking space is received within a first preset time, a first target path is planned by taking the obtained current position of the first terminal as a starting point and the first target parking space as an end point, and the first target path is returned to the first terminal; otherwise, the parking space sharing server automatically selects a second target parking space from at least one candidate parking space, similarly plans a second target path by taking the obtained current position of the first terminal as a starting point and the second target parking space as an end point, and returns the second target path to the first terminal.
In the embodiment of the application, the current parking space state of at least one candidate parking space can be updated at an adaptive time, and the updating time is that when the parking space sharing server receives the target area range parking space state identification map corresponding to the candidate parking space, the parking space sharing server updates the target area range parking space state identification map.
Based on the above specific embodiment, after the space sharing server returns the first target route to the first terminal, the current space state of the first target space may be changed, for example, the first target space may be occupied by another vehicle in the process that the first terminal travels according to the first target route.
Therefore, in an optional implementation manner, after the parking space sharing server returns the first target path to the first terminal, the following steps may be further included:
when the second preset time is reached, if the first terminal is determined not to reach the first target parking space or the exit path navigation request sent by the first terminal is not received, executing the steps again: and returning the at least one candidate parking space in the target area parking space state identification diagram to the first terminal if the at least one candidate parking space is determined to exist in the target area parking space state identification diagram and the current parking space state of the at least one candidate parking space is the first parking space state according to the target position information.
Specifically, the parking space sharing server starts timing from the moment of returning to send the first target path to the first terminal; if the parking space sharing servers do not receive the exit path navigation request sent by the first terminal within the second preset time; or, when the second preset time is reached, the parking space sharing server acquires the current position of the first terminal, and determines whether the first terminal has reached or is about to reach the first target parking space according to the current position, and when it is determined that the first terminal is further away from the first target parking space, the first terminal does not reach the first target parking space in the driving process, and at this time, the parking space sharing server needs to execute step S219 again to re-determine whether at least one candidate parking space exists in the target area parking space state identification map. If the result of the re-judgment is the same as the previous time, or the first target parking space is still in the re-determined at least one candidate parking space, no change is made; and if the current parking space state of the first target parking space is changed from available to unavailable, the parking space sharing server sends the re-determined at least one candidate parking space to the first terminal and reminds the first target parking space to be occupied.
Steps S213 to S223 and alternative embodiments thereof are described below with a specific scenario. As shown in fig. 6, the scene is a parking space information sharing scene, and includes a vehicle 601 and a parking space sharing server 602; in conjunction with the above description of the parking space information collection scenario, the parking space sharing server 602 is equivalent to the parking space sharing server 304, except that the role of the parking space sharing server 602 in the scenario is different. When a user of a vehicle 601 searches a parking lot through a vehicle central control display screen, a VCU of the vehicle 601 judges that the vehicle is in a parking space finding state at the moment, and sends a parking space recommendation request to a parking space sharing server through wireless, wherein the parking space recommendation request comprises the position of the parking lot; if the parking space sharing server 602 determines that it is located within the target area of the road end server 304 according to the position of the nearby parking lot, the parking space sharing server 602 determines that the parking space is the target area parking space state identifier map shown in fig. 5 from the area parking space state identifier map set; then, the parking space sharing server 602 determines, according to the position of the parking lot, a parking space in the target area parking space state identification diagram, where the parking space state in the parking lot position is an available state, as a candidate parking space, and if the position of the parking lot is exactly the parking lot where parking space a and parking space B are located, the parking space sharing server takes parking space a as the candidate parking space and returns the candidate parking space to the vehicle 601; after receiving the candidate parking spaces sent by the parking space sharing server 602, the vehicle 601 selects one candidate parking space as a target parking space, that is, the parking space a can be selected as the target parking space, and the selection information is returned to the parking space sharing server 602, and the parking space sharing server 602 can perform parking space path navigation according to the acquired current position of the vehicle 601 and the positioning information of the parking space a, and return the parking space path navigation to the vehicle 601. It should be noted that the vehicle 601 in the parking space information sharing scenario may be the vehicle 301 or the vehicle 302 in the above parking space information collecting scenario.
In summary, the parking space information processing method provided by the embodiment of the present application includes the parking space information collection method in steps S201 to S211 and the parking space information sharing method introduced in steps S213 to S223. The parking space information is mainly collected by the terminal and is uploaded to the parking space sharing server at the cloud after being processed by the road side server. The process can be realized based on the configuration of the vehicle-mounted sensor required by the current auxiliary driving, additional investment is not required to be added to the vehicle, and the parking space information in a larger area range can be collected through the crowd funding of the vehicle. When the terminal has a parking demand, the parking space information of the destination can be obtained from the cloud parking space sharing server in advance, and the parking space information does not need to be obtained when the vehicle enters a parking lot or arrives at a specific scene near the parking space, so that the time for searching the parking space by the vehicle can be saved.
