Description
Technical Field
The present application relates to a parking space guidance mechanism, and in particular, to a parking space navigation system and method, and a storage medium.
Background
In recent years, with the rapid development of economy and the improvement of the living standard of people, the holding capacity of private cars is also increased sharply, and particularly in some large and medium-sized cities, the number of motor vehicles reaches the scale of millions. On the other hand, the speed increase of the parking space is far from matching the speed increase of the automobile holding amount. Although private cars offer great convenience, the attendant problem of increasingly serious parking difficulties also presents a significant challenge. Especially in some key areas of cities, such as hospitals, schools, scenic spots and the like, traffic congestion caused by parking problems becomes daily meal. The parking problem seriously affects the normal travel of residents at present, in recent years, partial parking problem can be relieved to a certain extent through measures such as time-sharing parking in office buildings and the like, but the problem of difficulty in parking in hot spot areas is not an effective solution. Because city planning limits, supply also unrealistic under many situations just by increasing the parking stall, along with the development of car networking technique, for solving the difficult problem of hot spot regional parking, provide a new thinking through the mode of intelligent guide.
The existing hot spot area may be equipped with a display terminal to be networked with the nearby parking lots, and the display terminal may dynamically display the vacancy states of the nearby parking lots and may also be regarded as a guidance system. However, the system needs the driver to visually see the information to help the parking, and because the system can only display the vacancy information, how to reach the parking lot and the related information of the parking spaces and the charging information of the parking lot are not visually displayed, the system cannot effectively help the driver who is not familiar with the nearby road conditions.

Detailed Description
For the purposes of brevity and explanation, the principles of the present application are described herein with reference primarily to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equally applicable to all types of parking space navigation systems and methods, storage media, and that these same or similar principles may be implemented therein, with any such variations not departing from the true spirit and scope of the present application.
Fig. 1 shows a common traffic scenario in which parking space navigation system 10 includes vehicle 102, roadside parking lot 104, indoor parking lot 106, indoor parking lot 108, roadside communication system 112, and base station 114. In the three typical parking lots in the figure, the roadside parking lot 104 is located closer to the vehicle 102, the indoor parking lot 108 is located farther from the vehicle 102, and the distance from the vehicle 102 to the parking lot 106 is between the distances from the vehicle 102 to the roadside parking lot 104 and the indoor parking lot 108. More specifically, if each parking lot and vehicle are equipped with a communication unit such as V2X, roadside parking lot 104 can communicate directly with vehicle 102, indoor parking lot 106 can relay communication with vehicle 102 via roadside communication system 112, and indoor parking lot 108 needs to communicate with vehicle 102 via a public network (the public network includes infrastructure in the figure, base station 114). How each part of the scenario works will be explained in detail below, and the subsystems described below can work independently of each other to accomplish the tasks set forth herein.
According to an aspect of the present application, a parking space navigation system is provided. As shown in fig. 2, the parking space navigation system 20 includes a vehicle communication unit 202 and a vehicle navigation unit 204. Wherein, the vehicle-mounted communication unit 202 is configured to receive the first parking space information from the parking lot subsystem, the second parking space information from the road-side communication system and the third parking space information from the public network communication system according to the signal coverage condition. The parking space information in this document is intended to refer to information relating to a parking space and its belonging parking lot. The first, second, and third parking space information described herein are only intended to distinguish their transmission subjects, and these information may be consistent in content and format.
Specifically, returning to fig. 1, the parking space navigation system 20 and the vehicle-mounted communication unit 202 and the vehicle-mounted navigation unit 204 included therein may be, for example, components of the vehicle 102, and may be formed by general-purpose or special-purpose components of the vehicle. The first parking space information from the parking subsystem includes parking space information directly from the roadside parking lot 104, the indoor parking lot 106 or the indoor parking lot 108, for example, when the vehicle 102 travels along the right side of the road from far to near to the crosswalk direction, communication can be established with the indoor parking lot 108, the indoor parking lot 106 and the roadside parking lot 104, respectively. When traveling to the illustrated position, the vehicle 102 can directly communicate only with the roadside parking lot 104, and thus the first parking space information received by the in-vehicle communication unit 202 at this time includes only the parking space information from the roadside parking lot 104.
At the same time, the vehicle 102 is also capable of receiving second seat information from a roadside communication system 112, the roadside communication system 112 being integrated with the transportation facility as shown in FIG. 1. If the parking lot may establish communication with the roadside communication system 112, the roadside communication system 112 may collect first parking space information from the communicable parking lot and generate second parking space information therefrom, which may be identical, similar, or different in form and content from the first parking space information. The roadside communication system 112 may receive and buffer the first bit information and broadcast the second bit information generated therefrom at a certain period. The roadside communication system 112 receives the parking lot information, inquires whether the parking lot record exists in the cache, if so, updates the original entry, and otherwise, creates a new entry for the parking lot. For example, the second parking space information received by the vehicle-mounted communication unit 202 may be processed from the first parking space information from the roadside parking lot 104 and the indoor parking lot 106.
The in-vehicle navigation unit 204 is configured to generate navigation information regarding available parking spaces based on information (e.g., which may be one or more of first parking space information, second parking space information, and third parking space information) received by the in-vehicle communication unit 202. In some examples, the navigation information may indicate information such as a parking lot with available slots, a parking lot to which available slots belong, and/or a number of available slots in the parking lot, which may be derived directly from or processed from the received slot information. The navigation information may be displayed on a touch display of the vehicle 102 to facilitate user click confirmation. The position information in the corresponding parking lot (or parking space) entry selected by the driver is transmitted to the car navigation unit 204, and the car navigation unit 204 plans a route to the target parking lot (or parking space) according to the position information and finally guides the user to the parking lot.
In some embodiments of the present application, the parking space information (the first parking space information, the second parking space information, and the third parking space information) may include one or more of the following items: the parking lot identification code, the parking lot charging standard, the number of free parking spaces in the parking lot and the type thereof (e.g., mechanical parking spaces, fixed parking spaces), the size of the free parking spaces in the parking lot (e.g., bus, large, medium, and small), the entrance position of the parking lot (e.g., longitude and latitude), whether the parking lot is underground, new energy charging pile information (e.g., whether the free parking spaces are equipped with charging piles, charging pile standards, etc.). The parking space information may also include position information of the free parking spaces in the parking lot, for example, their codes or specific positions in the parking lot.
In some embodiments of the present application, the in-vehicle navigation unit 204 ranks the available parking spaces in the navigation information according to at least one of the first parking space information, the second parking space information, and the third parking space information. In some cases, the available parking spaces and parking lots may not be unique, so that it is necessary to recommend the optimal parking space for the user, thereby reducing the difficulty of screening for the user. Specifically, the available parking spaces may be sorted according to a certain rule, the best parking spaces are arranged at the front positions, and the least recommended parking spaces are arranged at the rear positions.
In some embodiments of the present application, the on-board navigation unit 204 is ranked according to at least one of: distance of parking lot entrance, parking lot charging criteria, parking lot free space type (e.g., mechanical space, fixed space) and free space size (e.g., bus, large, medium, small), whether the parking lot is underground. For example, the in-vehicle navigation unit 204 may arrange the parking lot and its parking spaces closest to the parking lot entrance at the front position; the in-vehicle navigation unit 204 may also arrange the lowest-charged parking lot or space at the front position. If the user has a preference, the car navigation unit 204 may also arrange the parking space information according to the preference set by the user in advance or set immediately, for example, if the user prefers a fixed parking space, the car navigation unit 204 may arrange the fixed parking space at a front position and arrange the mechanical parking space at a rear position.
The car navigation unit 204 may also sort the available slots according to several criteria. For example, the in-vehicle navigation unit 204 may arrange the nearest underground parking space in a forward position according to the setting. The above schematically describes the ranking scheme of the car navigation unit 204 according to various criteria, and the car navigation unit 204 may also quantize each adoptable criterion and assign a weight to each adoptable criterion, and may combine the adoptable criterion and the weight thereof in ranking.
The in-vehicle navigation unit 204 may also consider that the user sets in advance and sorts in conjunction with actual time, location, and the like. For example, if the user previously set the model of the self-contained vehicle 102 as a medium-sized SUV, it is generally necessary to park in a medium-sized vacant space, and the medium-sized space may be more expensive than the small-sized space, especially for time-based charging (rather than time-based charging). In some examples, if the time that the in-vehicle navigation unit 204 generates the navigation information is eight nights and there are multiple immediately-free small-size slots in the surroundings, then the navigation unit 204 may recommend one of the several immediately-free small-size slots to the user and rank the result forward. As another example, if the time at which the in-vehicle navigation unit 204 generates the navigation information is eight am, and it is expected that even if there is an immediately empty small-sized parking space, it is subsequently filled, the navigation unit 204 may recommend the medium-sized parking space to the user.
In some embodiments of the present application, the sorting may also be performed according to historical selections of the user, for example, sorting the parking spaces/parking lots that the user confirms to use for multiple times in the front position.
In some embodiments of the present application, the car navigation unit 204 is further configured to initiate an evaluation request for available parking spaces according to information received by the car communication unit 202 (e.g., one or more of the first parking space information, the second parking space information, and the third parking space information may be used), the car communication unit 202 forwards the evaluation request and receives evaluation information about the evaluation request from, for example, a server, and the car navigation unit 204 performs ranking according to the evaluation information. The service provider to which the server belongs can establish an evaluation database for the parking space/parking lot, and evaluation information in the database can be formed according to feedback of the user. When other users have parking requirements, evaluation information of interested parking lots (for example, a plurality of surrounding parking lots) and parking spaces thereof can be pulled from the server. The car navigation unit 204 may further perform ranking according to the evaluation information of each parking lot and its parking spaces, for example, the car navigation unit 204 may filter out parking spaces/parking lots with poor evaluation and prioritize the parking spaces/parking lots with better evaluation.
In some embodiments of the present application, the vehicle-mounted communication unit 202 communicates based on the V2X protocol, and the roadside parking lots 104, the indoor parking lots 106, the indoor parking lots 108, the roadside communication system 112, and the base station 114 may also support the V2X communication protocol. V2X is a car networking technology for realizing information interaction between a car and the outside through relevant protocol standards. V2X specifically includes: vehicle-to-vehicle communication (V2V), vehicle-to-infrastructure communication (V2I), vehicle-to-person communication (V2P), and vehicle-to-network communication (V2N). The V2X supports a range of short-range communication, for example, the communication with the V2X unit of the parking lot can be realized through the vehicle-mounted V2X device, so that the interaction of the information of the parking lot is realized, and the driver is further guided to quickly find the parking lot with a free parking space. In addition, V2X also supports communication over LTE networks in domestic standard C-V2X, whereby parking lot information outside short-range communication distances can be further collected and ultimately transmitted to onboard V2X devices.
Nearby parking lot information is transmitted to the vehicle-mounted V2X device in real time through the V2X technology, and the vehicle-mounted navigation system assists the driver to arrive at the selected parking lot after the driver makes a selection. The example aims at the problem of parking difficulty in the hot spot area, and the vehicle is guided to the available parking lot through the V2X communication technology, so that the driver saves time, and on the other hand, the problem of congestion caused by the parking difficulty in the hot spot area can be relieved.
In some embodiments of the present application, the in-vehicle navigation unit 204 also generates navigation information based on at least one of: satellite positioning, base station assisted positioning and indoor positioning. The car navigation unit 204 may also receive satellite positioning signals, base station assisted positioning signals, and indoor positioning signals, so that the position of the vehicle 102 may be determined. At this time, the navigation information may include a planned path of the vehicle 102 to an available space.
According to another aspect of the application, a parking space navigation method is provided. As shown in fig. 3, the parking space navigation method 30 includes the following steps. Receiving at least one of the following items in step S31: the parking lot system comprises first parking space information from a parking lot subsystem, second parking space information from a roadside communication system and third parking space information from a public network communication system, wherein the second parking space information and the third parking space information are generated according to the first parking space information. Navigation information about available slots is generated in step S32 from the information received in step S31.
The parking space navigation method 30 receives at least one of the following items in step S31: the parking lot system comprises first parking space information from the parking lot subsystem, second parking space information from the roadside communication system and third parking space information from the public network communication system. Specifically, as shown in fig. 1, the first parking space information from the parking lot subsystem includes parking space information directly from the roadside parking lot 104, the indoor parking lot 106, or the indoor parking lot 108, for example, when the vehicle 102 travels along the right side of the road from far to near to the crosswalk direction, communication with the indoor parking lot 108, the indoor parking lot 106, and the roadside parking lot 104 may be established, respectively. When traveling to the illustrated position, the vehicle 102 can directly communicate only with the roadside parking lot 104, and thus the first parking space information received at step S31 at this time includes only the parking space information from the roadside parking lot 104.
At the same time, the vehicle 102 is also capable of receiving second seat information from the roadside communication system 112. A roadside communication system integrated with a transportation facility is shown in fig. 1, which may collect first parking space information from various parking spaces and generate second parking space information therefrom, if the parking spaces may establish communication with the roadside communication system 112, which may be identical, similar, or different in form and content from the first parking space information. The roadside communication system 112 may receive and buffer the first bit information and broadcast the second bit information generated therefrom at a certain period. The roadside communication system 112 receives the parking lot information, inquires whether the parking lot record exists in the cache, if so, updates the original entry, and otherwise, creates a new entry for the parking lot. For example, the second parking space information received in step S31 may be processed from the first parking space information from the roadside parking lot 104 and the indoor parking lot 106.
The parking space navigation method 30 generates navigation information regarding available parking spaces according to the information (e.g., one or more of the first parking space information, the second parking space information, and the third parking space information) received in step S31 in step S32. In some examples, the navigation information may indicate information such as a parking lot with available slots, a parking lot to which available slots belong, and/or a number of available slots in the parking lot, which may be derived directly from or processed from the received slot information. The navigation information may be displayed on a touch display of the vehicle 102 to facilitate user click confirmation. The position information in the corresponding parking lot (or parking space) entry selected by the driver is transmitted to the car navigation unit 204, and the car navigation unit 204 plans a route to the target parking lot (or parking space) according to the position information and finally guides the user to the parking lot.
In some embodiments of the present application, the parking space information (the first parking space information, the second parking space information, and the third parking space information) may include one or more of the following items: the parking lot identification code, the parking lot charging standard, the number of free parking spaces in the parking lot and the type thereof (e.g., mechanical parking spaces, fixed parking spaces), the size of the free parking spaces in the parking lot (e.g., bus, large, medium, and small), the entrance position of the parking lot (e.g., longitude and latitude), whether the parking lot is underground, new energy charging pile information (e.g., whether the free parking spaces are equipped with charging piles, charging pile standards, etc.). The parking space information may also include location information of free parking spaces in the parking lot, for example, their codes or specific locations in the parking lot.
In some embodiments of the present application, the available parking spaces in the navigation information may be sorted according to at least one of the first parking space information, the second parking space information, and the third parking space information in step S32. In some cases, the available parking spaces and parking lots may not be unique, so that it is necessary to recommend the optimal parking space for the user, thereby reducing the difficulty of screening for the user. Specifically, the available parking spaces may be sorted according to a certain rule, the best parking spaces are arranged at the front positions, and the least recommended parking spaces are arranged at the rear positions.
In some embodiments of the present application, the ranking in step S32 may be according to at least one of the following: distance of parking lot entrance, parking lot charging criteria, parking lot free space type (e.g., mechanical space, fixed space) and free space size (e.g., bus, large, medium, small), whether the parking lot is underground. For example, the parking lot closest to the parking lot entrance and its parking spaces may be arranged at the front position in step S32; the parking lot or space with the lowest charge may also be arranged at the front position in step S32. If the user has a preference for use, the parking space information may be arranged according to a preference set by the user in advance or set immediately in step S32, for example, if the user prefers a fixed parking space, the fixed parking space may be arranged at a front position and the mechanical parking space may be arranged at a rear position in step S32.
In step S32, the available parking spaces may be ranked according to several criteria. For example, the nearest underground parking space may be arranged at a front position according to the setting in step S32. The above schematically describes the sorting scheme according to various criteria in step S32. In step S32, each of the adoptable criteria may be quantized and weighted, and the adoptable criteria and their weights may be combined in the sorting.
In step S32, the user may set and sort the time, the location, and the like in advance. For example, if the user previously configured the self-contained vehicle 102 as a medium-sized SUV, it would typically be desirable to park in a medium-sized vacant space, which may be more expensive than a small-sized space, particularly for time-based (rather than time-based) charging. In some examples, if the time of generating the navigation information in step S32 is eight nights and there are a plurality of immediately vacant small-sized slots around, then one of the several immediately vacant small-sized slots may be recommended to the user in step S32 and the result may be ranked ahead. As another example, if the time at which the navigation information is generated in step S32 is eight am, and it is expected that even if there is an immediately empty small-size slot, it is subsequently filled, a medium-size slot may be recommended to the user in step S32.
In some embodiments of the present application, the sorting may also be performed according to historical selections of the user, for example, sorting the parking spaces/parking lots that the user confirms to use for multiple times in the front position.
In some embodiments of the present application, it is further configured in step S32 to initiate an available parking space evaluation request according to the information received in step S31 (e.g., one or more of the first parking space information, the second parking space information, and the third parking space information may be, for example), such as the vehicle-mounted communication unit forwarding the evaluation request and receiving evaluation information about the evaluation request from, for example, a server, and then sorting according to the evaluation information. The service provider to which the server belongs can establish an evaluation database for the parking space/parking lot, and evaluation information in the database can be formed according to feedback of the user. When other users have parking requirements, evaluation information of interested parking lots (for example, a plurality of surrounding parking lots) and parking spaces thereof can be pulled from the server. In step S32, the parking lots and the parking spaces may be further sorted according to their evaluation information, for example, in step S32, parking spaces/parking lots with poor evaluation may be filtered out, and the parking spaces/parking lots with better evaluation may be prioritized.
In some embodiments of the present application, the in-vehicle communication units communicate based on a V2X protocol, such as roadside parking lots, indoor parking lots, roadside communication systems, and base stations may also support the V2X communication protocol.
According to an aspect of the present application, a parking space navigation system is provided. As shown in fig. 4, parking space navigation system 40 includes parking lot subsystem(s) 401, roadside communication system(s) 402, public network communication system(s) 403, and vehicle subsystem 404.
The parking lot subsystem 401 includes a parking space monitoring unit and a parking lot communication unit (not shown in fig. 4), the parking space monitoring unit is configured to monitor first parking space information of the parking lot, and the parking lot communication unit is configured to send the first parking space information. The parking subsystem 401 may include a server for maintaining the parking space information, for collating the information collected by the space monitoring units and transmitting the collated information via the parking lot communication unit. Returning to fig. 1, the roadside parking lot 104, the indoor parking lot 106, or the indoor parking lot 108 each include a parking space monitoring unit and a parking lot communication unit. For example, a parking space monitoring unit of the roadside parking lot 104 may monitor information of all parking spaces within the roadside parking lot 104. Information such as the size and type of each parking space in the roadside parking lot 104 may be collected in advance, and the parking space monitoring unit may be configured to monitor whether each parking space is free. The parking space monitoring unit can include a sensor for detecting whether a vehicle is parked in the parking space by using infrared rays, and if the vehicle is parked in the parking space, the sensor cannot receive the emitted infrared rays, so that the parking space monitoring unit can judge that the current parking space is occupied. When the number of the idle parking spaces is counted, the parking space monitoring unit considers vehicles which enter a parking lot and are still searching for the parking spaces, and the parking space monitoring unit needs to update the parking spaces in real time when the parking space state changes.
The parking lot communication unit is used to transmit (e.g., broadcast) various information of the parking lot and its parking spaces to the outside.
The roadside communication system 402 is configured to receive and buffer first vehicle location information from parking lot communication units and periodically broadcast second vehicle location information generated therefrom. Returning to fig. 1, which shows a roadside communication system integrated with a transportation facility, if parking lots can establish communication with the roadside communication system 112, it may collect first parking space information from the respective parking lots and generate therefrom second parking space information, which may be identical, similar, or different in form and content from the first parking space information. The roadside communication system 112 may receive and buffer the first bit information and broadcast the second bit information generated therefrom at a certain period. For example, the second parking space information may be processed from the first parking space information from the roadside parking lot 104 and the indoor parking lot 106.
The public network communication system 403 is configured to receive the first parking space information from the parking lot communication unit and to forward the third parking space information generated therefrom. In fig. 1, a base station 114 belonging to a public network communication system is shown, with which various parking lots and vehicles within the network coverage can establish communication. The slot information sent by the base station 114 may be pushed to vehicles within a certain range (from the base station 114 or parking lot). Only one base station is shown in the figure, and the number of base stations of the public network communication system can be expanded according to the network requirements. The parking lot and the vehicle can be respectively connected to different base stations of the public network communication system, and the invention does not limit the type of the base station, for example, the base station 114 can support one or more of GSM, CDMA, WCDMA, CDMA2000, TD-SCDMA, LTE-TDD, LTE-FDD, NR, etc. The third parking space information may be generated according to the first parking space information, and for example, the third parking space information may be collectively forwarded from the first parking space information from multiple sources, or may be relayed separately. For example, the third parking space information may be processed from the first parking space information from the roadside parking lot 104, the indoor parking lot 106, and the indoor parking lot 108, and the third parking space information may be identical, similar, or different in form and content from the first parking space information or the second parking space information.
