[0033] In order to make the technical problems to be solved, technical solutions and beneficial technical effects of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the protection scope of the present application.

[0034] Figure 1 Shows a working flowchart of a method for determining a target parking space in a parking lot according to an exemplary embodiment of the present application. The following exemplary embodiments describe the method according to the present application in more detail.

[0035] As Figure 1 shown, the method may include steps S1 to S3. In step S1, the identification information of the vehicle at the entrance of the parking lot of the building can be identified, and a communication connection with the identified vehicle 1 can be established. When a user drives a vehicle to a large building such as a shopping mall, museum, or office building, it is usually necessary to first park the vehicle in the parking lot equipped with the building, especially the underground parking lot, and then walk from the parking lot to the travel destination in the building, such as a store, restaurant, or restroom. As Figure 2 shown in a driving scenario diagram according to an exemplary embodiment of the present application, the vehicle 1 travels to the front of the gate 3 at the entrance of the parking lot of the building, thereby triggering the field-end camera 21 arranged at the entrance of the parking lot of the building to identify the identification information of the vehicle 1, especially the license plate information, thereby triggering the process of the parking space management system 2 equipped with the building to allocate a suitable target parking space for the vehicle 1. As Figure 3 shown in a system architecture diagram according to an exemplary embodiment of the present application, a vehicle-to-infrastructure (V2I) communication connection can be established through the field-end communication unit 22 of the parking space management system 2 of the building and the in-vehicle communication unit 11 of the vehicle 1, thereby realizing direct information interaction between the vehicle 1 and the parking space management system 2 of the building.

[0036] After establishing a communication connection between the vehicle and the infrastructure, a method for automatic parking is started on the vehicle side. As Figure 4 FIG. shows a flowchart of a method for automatic parking according to an exemplary embodiment of the present application, and the method may include steps S1' and S2'.

[0037] In step S1', in the case of establishing a communication connection with the parking management system 2, the obtained travel destination and route preference information may be sent to the parking management system 2 through the established communication connection. The user can input the desired travel destination through the human-machine interaction unit 12, such as an in-vehicle voice system, a central control display screen, etc., such as a store, a restaurant, a restroom, etc. in the building. In addition, during the use of the automatic parking system 10, the user can also preset route preference information through the human-machine interaction unit 12. The route preference information may include, for example, one or more of the following items: staircase usage preference information, which is used to characterize the user's acceptance of using the staircase, especially when the willingness to exercise is relatively strong, the user will be more inclined to use the staircase instead of the elevator; elevator usage preference information, which is used to characterize the user's acceptance of using the elevator, especially when the user suffers from claustrophobia, etc., the user will try to avoid using the elevator to go upstairs; user physiological state information, which may include, for example, the user's age, gender, health level, etc., and based on the user physiological state information, the user's walking speed and / or climbing speed can be evaluated; disabled parking space preference information, in the case where the user has a physical disability, the priority use of disabled parking spaces can be set. These parking spaces are usually located beside the elevator and have a larger area, as Figure 2 shown, to facilitate the disabled to get on and off the vehicle and quickly take the elevator upstairs; female parking space preference information, in the case where the user is female and there are children in the vehicle, the priority use of female parking spaces can be set. These parking spaces are usually also located beside the elevator and have a larger area, as Figure 2 shown, to facilitate picking up and dropping off children with a stroller, and so on.

[0038] After the parking management system 2 receives the travel destination and route preference information from the vehicle 1, steps S2 and S3 of a method for determining a target parking space in the parking lot are continued in the parking management system 2. In step S2, in response to the travel destination and route preference information received from the vehicle 1, at least based on the travel destination, the route preference information, and the building floor plan information of the building, a target parking space may be determined from the available parking spaces in the parking lot so that the total travel time of the user to the travel destination is minimized. The building floor plan information of the building is stored in the site control unit 23 of the parking space management system 2, which includes the type of each parking space (such as including ordinary parking spaces, female parking spaces, disabled parking spaces, etc.) and location information, elevator location information (which is in Figure 2shown by an elevator marker) and stair position information (shown by a stair marker in Figure 2 ), as well as the position information of each operating unit in the building (including stores, restaurants, restrooms, etc.). The field control unit 23 of the parking space management system 2 can select a target parking space with the minimum total travel time from all currently available parking spaces based at least on the travel destination, the route preference information, and the building floor plan information (for example, Figure 2 the marked parking space 4 in ), and the total travel time is the sum of the first travel time from the current position of the vehicle 1 to the determined target parking space and the second travel time from the determined target parking space to the travel destination.

[0039] Considering that the elevators in the building may have different operating times for, for example, morning and evening rush hours, weekdays and holidays, etc., especially during certain periods the elevators may be out of service, and the waiting time for each elevator on the user's floor is different, especially in high-rise buildings the waiting time for the elevator may be up to several minutes. When determining the target parking space from the available parking spaces in the parking lot, the building equipment information can be additionally considered. The building equipment information may include, for example, the operating time and / or waiting time of the elevators in the building. Thus, at least based on the building floor plan information, stair usage preference information, the operating time and / or waiting time of the elevator, it can be determined whether the walking route from the target parking space 4 to the travel destination is via the stairs or the elevator to go upstairs. For example, when the elevator is not in the operating time, it is determined that the walking route goes upstairs via the stairs, or when the elevator waiting time exceeds the time to climb the stairs and the user prefers to use the stairs, it is determined that the walking route goes upstairs via the stairs.

[0040] Next, based on the user physiological state information and the building floor plan information, the complexity of the walking route from the determined target parking space 4 to the travel destination can be evaluated. Especially when the parking lot layout is large and complex, this complexity is used to characterize the walking difficulty of the user on the walking route. The higher the complexity, the greater the walking difficulty and the smaller the walking speed. At least based on the evaluated complexity, the second travel time of the walking route from the determined target parking space 4 to the travel destination can be estimated.

[0041] In addition, in the case where the user sets a preference for disabled parking spaces, the Figure 2 marked available disabled parking space can be selected as the target parking space, and a route suitable for disabled people from the target parking space to the travel destination can be determined. This route should avoid going up and down steps and use the elevator to go upstairs. In the case where the user sets a preference for female parking spaces, the Figure 2The marked available parking spaces for women are used as target parking spaces, and a route suitable for pushing a stroller, carrying a child, or leading a child to walk from the target parking space to the travel destination is designed. This route should also avoid going up and down stairs and use the elevator to go upstairs.

[0042] In step S3, information about the determined target parking space can be sent to vehicle 1. The information can include the location information of the determined target parking space and the walking route information from the target parking space to the travel destination. At the same time, the determined target parking space can be reserved for vehicle 1 based on the license plate information of vehicle 1, preventing the same parking space from being repeatedly allocated to other vehicles newly entering the parking lot.

[0043] After the automatic parking system 10 of vehicle 1 receives the information about the determined target parking space, step S2' of the method for automatic parking is executed on the vehicle side. In step S2', in response to the information about the determined target parking space received from the parking management system 2, vehicle 1 can be controlled to park in the determined target parking space, and the walking route information from the target parking space to the travel destination can be displayed to the user. Here, vehicle 1 can be controlled to drive near the determined target parking space and automatically park in the target parking space based on the parking lot map information and the driving environment information obtained by sensing and fusion units such as on-vehicle cameras, lidar, and / or millimeter-wave radars. Then, the walking route information can be displayed to the user through, for example, a central control display screen, a head-up display, etc. When the user's mobile terminal and / or wearable device (such as a smart watch, smart glasses, etc.) is in V2X communication connection with the vehicle, the walking route information can also be synchronously transmitted to the user's mobile terminal and / or wearable device through the on-vehicle communication unit 11, so that the user can still view the walking route after getting off the vehicle.

[0044] According to the embodiments of the present application, a target parking space that conforms to the user's habits and has the shortest travel time can be selected based on the user's travel destination and route preference information, and the walking route information from the target parking space to the travel destination can be displayed to the user, effectively solving the problem of how users choose a suitable parking space in a complexly laid-out parking lot and quickly find the entrance to the travel destination, thereby improving the travel convenience and parking experience of users.

According to the specific situation, the order can be changed as long as the technical purpose of the present application can be achieved.
