In some embodiments, the electronic map may include a topographic map, a grid topographic map, a remote sensing image map, an elevation model map, a thematic map, and the like. In some embodiments, the position of the electronic fence in the electronic map coordinate system may include mapping a predetermined coordinate position of a geographical area boundary to a corresponding position in the electronic map, for example, a virtual perimeter corresponding to a parking area on an electronic map. In some embodiments, the coverage area of the electronic fence in the electronic map coordinate system may include a predetermined coordinate location of a geographical area boundary mapped to an area enclosed by a corresponding location in the electronic map. In some embodiments, the determining module 220 may determine the position and the coverage area of the electronic fence according to the coordinate position on the electronic map and the area surrounded by the coordinate position of the geographical area boundary determined in step 310 in advance.

Optionally, in step 330, an image of the electronic map and an image of at least one electronic fence included in the electronic map may be displayed on a terminal; the image of electronic fence corresponds to the electronic fence, and is used to indicate a location and/or a coverage area of the electronic fence. Specifically, step 330 may be performed by the display module 230.

In some embodiments, the image of the electronic map may be displayed on a display interface of an electronic map application on a mobile terminal or a PC (Personal Computer) . For example, the bicycle interface of Didi ChuxingTM. In some embodiments, the image of electronic fence may indicate the location of the electronic fence and the coverage area on the image of the electronic map. In some embodiments, the shape of the geo-fence image may correspond to the scaled-down shape of the real geographic area. For example, if the real geographic area is a rectangular area of 50 meters by 50 meters, the electronic fence image may be a rectangle reduced in proportion, and the rectangle may be scaled according to the zoom of the display interface. In some embodiments, the display mode of the image of the electronic fence may include a dashed border and a transparent light blue in the middle region. In some embodiments, the electronic fence image may also be displayed in other ways (for example, the border is a stippled line, and the middle area is transparent light green) , which is not limited in this application. It can be understood that the display module 230 can map the location and coverage area of the electronic fence on the display interface of the electronic map application through GPS data points, thereby forming an image of the electronic fence.

In some embodiments, the image of the electronic fence may also be used to display the attributes of the electronic fence on the image of the electronic map. In some embodiments, the attributes of the electronic fence may include one or both of a parking electronic fence and a safety electronic fence. Geo-fence tags can include text and symbols to identify the attributes of different geo-fences. As shown in FIG. 6, the square area is the area covered by a parking electronic fence 630, and the largest circular area is the area covered by a safety electronic fence 610. In some embodiments, the images of different electronic fences may be identified with different colors (not shown in FIG. 6) . It should be noted that the boundary of each electronic fence in actual applications is not necessarily a regular circle or rectangle, and the electronic fence can present various shapes according to its coverage area.

In some embodiments, the parking electronic fence may be the smallest parkable area, such as a parking lot. In some embodiments, the safety electronic fence may be an operating area with a certain range, and the safety electronic fence may include one or more parking electronic fences. In some embodiments, based on the attributes of the electronic fence, the display module 230 may determine the operation authority of the vehicle and the display instructional content related to the electronic fence. Through the operation authority and display content displayed on a user terminal (for example, a rental car terminal of a rental car user) , the rental car user can order and borrow a car in an orderly manner. More descriptions about determining the operation authority and display content of the vehicle can be found elsewhere in this application (such as in the flow charts In FIG. 4 and FIG. 5 and related descriptions) and will not be repeated here.

In some embodiments, the attributes of the electronic fence may further include a field station aggregated electronic fence, which corresponds to one or more parking electronic fences, and the geographic area corresponding to the field station aggregated electronic fence covers the corresponding geographic area of the corresponding parking fence. As shown in FIG. 6, the field station aggregated electronic fence 620 includes a parking electronic fence 630, and the geographic area corresponding to the field station aggregated electronic fence 620 covers the geographic area corresponding to the parking electronic fence 630. Similarly, as shown in FIG. 7, the field station aggregated electronic fences 720-1 and 720-2 include parking electronic fences 730-1 and 730-2, respectively, and the geographic areas corresponding to the field station aggregated electronic fences 720-1 and 720-2 covers the geographic areas corresponding to the parking electronic fences 730-1 and 730-2, respectively.

In some embodiments, a parking area corresponding to a parking electronic fence may be referred to as a field station. Specifically, a field station aggregated electronic fence may correspond to one or more parking electronic fences. When corresponding to one parking electronic fence, the geographic area corresponding to the field station aggregated electronic fence can cover the geographic area corresponding to the parking electronic fence and expand a certain range based on the geographic area. For example, the geographical area boundary corresponding to the determined parking electronic fence can be expanded by one-meter outwards. The expanded geographical area boundary and the enclosed geographical area are the geographical areas corresponding to the field station aggregated electronic fence. When the field station aggregated electronic fence corresponds to multiple parking electronic fences, the geographic area corresponding to the field station aggregated electronic fence can cover the geographical area corresponding to each parking electronic fence and the area between these geographic areas, which can be understood as the field station at this time The aggregated electronic fence is a connected area; or, the geographic area corresponding to the field station aggregated electronic fence can cover the geographic area corresponding to each parking electronic fence. At this time, the field station aggregated electronic fence can include two or more separate areas. By mapping the geographic area corresponding to the field station aggregated electronic fence to the electronic map, the field station aggregated electronic fence can be displayed on the electronic map. In some embodiments, the number of vehicles in the aggregated electronic fence of the field station may also be counted, and the display module 230 may display the number of vehicles in the aggregated electronic fence of the one or more field stations in the image of the electronic map. For example, as shown in FIG. 6, the number of vehicles in the field station aggregated electronic fence can be displayed in the image of the electronic map near the parking electronic fence (e.g., “6” is displayed) . In some embodiments, the number of vehicles in the field station aggregated electronic fence may further include the number of vehicles whose distance from the field station aggregated electronic fence is less than a preset distance. In some embodiments, the preset distance may be 200 meters, 300 meters, or 400 meters. For example, the number of vehicles within a distance of 300 meters from the field aggregated electronic fence can be displayed in the image of the electronic map together with the number of vehicles within the area covered by the field station aggregated electronic fence.

In some embodiments, the display module 230 may display vehicle dispatch information in an image of the electronic map based on the number of vehicles in the electronic fence aggregated by one or more field stations. The image of the electronic map may be displayed on the dispatch terminal of the vehicle dispatcher, for example, as shown in FIG. 7. vehicles may be displayed on the dispatch terminal of the vehicle dispatcher to facilitate the vehicle dispatcher to perform vehicle dispatch.

In some embodiments, the vehicle dispatch information may include at least one of a dispatch reminder, a dispatch direction, a dispatch number, and dispatch navigation information. In some embodiments, the dispatch reminder may be a reminder to send a message to a dispatch terminal of a vehicle dispatcher to inform that dispatch is required when the number of vehicles in an aggregated electronic fence in a field station is less than a threshold. In some embodiments, the dispatch direction may be a prompt indicating the need to dispatch from a certain field station aggregated electronic fence to another field station aggregated electronic fence. For example, as shown in FIG. 7, the arrow indicates that vehicle needs to be dispatched from the field station aggregated electronic fence 720-2 to the field station aggregated electronic fence 720-1. In some embodiments, for a field station aggregated electronic fence with fewer vehicles, transfers of vehicles from other one or more field station aggregated electronic fences may be received. In some embodiments, the dispatched number may be the number of vehicles dispatched from a certain field station aggregated electronic fence to another field station aggregated electronic fence. For example, as shown in FIG. 7, the number of vehicles dispatched from the field station aggregated electronic fence 720-2 to the field station aggregated electronic fence 720-1 is two. In some embodiments, the dispatch navigation information may be a travel path scheduled from a certain field station aggregated electronic fence to another field station aggregated electronic fence. For example, as shown in FIG. 7, the travel path from the field station aggregated electronic fence 720-2 to the field station aggregated electronic fence 720-1 is shown as a dotted line 750. Through the vehicle dispatch information on the display interface of the electronic map application of the dispatch terminal, the vehicle dispatcher can order the vehicles in an orderly manner. More descriptions of vehicle dispatch can be found elsewhere in this application such as in flow chart of FIG. 5 and related descriptions and will not be repeated here.

In step 340, the position information of the vehicle may be acquired. Specifically, this step 340 may be performed by the obtaining module 210. In some embodiments, the position or location information of the vehicle may include GPS coordinate data points of the vehicle in an electronic map. In some embodiments, the obtaining module 210 may obtain a GPS data point of the vehicle and map the position information of the vehicle onto an electronic map.

In step 350, a relative positional relationship between the vehicle and at least one electronic fence may be determined based on the position information of the vehicle and the boundary position information of the electronic fence. Specifically, this step 350 may be performed by the determining module 220.

In step 360, an operation of the vehicle may be authorized based on the relative positional relationship and an attribute of the electronic fence. Specifically, this step 360 may be performed by the determining module 220. Subsequently, instructional content of the authorized operation is then prompted on a terminal accordingly. Specifically, this step may be performed by the display module 230.

It should be noted that the above description of the process 300 is merely for the purpose of illustration and description, and does not limit the scope of application of the present disclosure. For those skilled in the art, various modifications and changes can be made to the process 300 under the guidance of this application. However, these amendments and changes are still within the scope of this application. For example, step 320 may determine only the position of the electronic fence in a certain electronic map coordinate system, and in step 330, the display module 230 may display the image of electronic fence and its enclosure according to the position of the electronic fence in a certain electronic map coordinate system and coverage area.

FIG. 4 is an example flowchart of a method 400 for determining an instructional content to be prompted on a terminal according to some embodiments of the present disclosure. Specifically, FIG. 4 is a flow chart illustrating the processes of FIG. 3 implemented in different positional relationships relative to a safety or parking electronic fence, according to some embodiments of the present disclosure. In some embodiments, the process 400 may be performed by processing logic, which may include hardware (e.g., circuits, dedicated logic, programmable logic, microcode, etc. ) , software (running on a processing device to perform hardware simulation Instructions) , etc. or any combination thereof. One or more operations in the method 400 for determining the operation authority of the vehicle shown in FIG. 4 may be implemented by the on-demand service system 100 shown in FIG. 1. For example, the process 400 may be stored in the storage device 130 in the form of instructions and executed by the processing engine 112.

Step 410 provides the specifics of the relative positional relationship determined by step 360 of FIG. 3, i.e. based on the relative positional relationship and an attribute such as safety or parking of the at least one electronic fence, an operation of the vehicle is authorized, for example by the determination module 220 and an instructional content reflecting the authorized operation is then prompted for example by the display module 230 on a terminal accordingly.

In some embodiments, the operation authority of the vehicle may include permitting return of the vehicle or prohibiting use of the vehicle. In some embodiments, the display content related to the electronic fence may include effective car return controls, text prompts, or navigation information. In some embodiments, the operation authority of the vehicle and/or the display content related to the electronic fence may be displayed on the car rental terminal of the rental, so that a corresponding operation can be performed, such as returning or using the car. In some embodiments, the determination module 220 may determine the operation authority of the vehicle and/or the display content related to the electronic fence based on the relative positional relationship and the attributes of the electronic fence.

If the vehicle is located in a parking electronic fence, subsequent authorization and prompting is represented by step 420. Specifically, the determination module 220 may determine that the operation permission of the vehicle is to allow returning of the vehicle, and may display an effective return control (such as a return button) on the vehicle user interface or display a text prompt ( (E. g. "click to return car" ) .

If the vehicle is located outside the safety electronic fence, subsequent authorization and prompting is represented by step 430. Specifically, the determination module 220 may determine that the operation authority of the vehicle is prohibited to use the vehicle, and may display a text prompt on the vehicle user interface (for example, "prohibited to use the vehicle" or "please use the vehicle within the specified area" ) .

If the vehicle is located outside the parking electronic fence and within the safety electronic fence, and the distance between the vehicle and one or more parking electronic fences is less than a first preset threshold, subsequent authorization and prompting is represented by step 440. Specifically, the determination module 220 may determine one or more navigational information for guiding the vehicle to a parking electronic fence. For example, as shown in FIG. 6, a vehicle A or a vehicle B located outside the parking electronic fence 630 and inside the safety electronic fence 610 can respectively display the

navigation routes

650 and 660 to the parking electronic fence 630 on the image of the electronic map. In some embodiments, the first preset threshold distance may be set manually in advance. For example, the first preset threshold distance may be 100 meters, 200 meters, or 300 meters. In some embodiments, the distance from the vehicle to the parking electronic fence may be a straight-line distance or may be a calculated distance for the vehicle navigation route. In some embodiments, the determination module 220 may determine the relative positional relationship between the vehicle and the electronic fence according to the GPS data point of the vehicle and the boundary position information of the electronic fence.

In some embodiments, the navigation information may include one or both of an entrance to a parking electronic fence and a navigation route. The user can return the car according to the prompt of the navigation information. For example, as shown in FIG. 6, the navigation information from the vehicle A and the vehicle B to the parking electronic fence 630 includes the entrance 640 and the

navigation routes

650 and 660 to the parking electronic fence, respectively. According to the above navigation information, the user can accurately return the vehicle to the designated parking electronic fence.

It should be noted that the above description of the process 400 is merely for illustration and description and does not limit the scope of application of the present disclosure. For those skilled in the art, various modifications and changes can be made to the process 400 under the guidance of the present disclosure. However, these amendments and changes are still within the scope of this application.

FIG. 5 is an example flowchart illustrating the processes of FIG. 3 implemented in positional relationships relative to a field station aggregated electronic fence, according to some embodiments of the present disclosure. In some embodiments, the process 500 may be performed by processing logic, which may include hardware (e.g., circuits, dedicated logic, programmable logic, microcode, etc. ) , software (running on a processing device to perform hardware simulation) Instructions) , etc. or any combination thereof. One or more operations in the vehicle dispatch method 500 based on the electronic fence display mode shown in FIG. 5 may be implemented by the on-demand service system 100 shown in FIG. 1. For example, the process 500 may be stored in the storage device 130 in the form of instructions and executed by the processing engine 112.

Step 510 provides the specifics of the relative positional relationship determined by steps 360 of FIG. 3, i.e. based on the relative positional relationship and an attribute of a field station aggregated electronic fence, an operation of the vehicle is authorized, for example by the determination module 220 and an instructional content reflecting the authorized operation is then prompted for example by the display module 230 on a terminal accordingly.

In some embodiments, the location information of the vehicle may include GPS coordinate data points of the vehicle in an electronic map. In some embodiments, the obtaining module 210 may obtain a GPS data point of the vehicle and map the position information of the vehicle onto an electronic map.

When the terminal is either a user or a dispatcher terminal, the at least one electronic fence is a field station aggregated electronic fence that corresponds to a predetermined geographic area and encompasses at least one parking electronic fence, and the predetermined geographic area corresponding to the parking electronic fence is inside the predetermined geographic area corresponding to the field station aggregated electronic fence, subsequent determination and displaying steps are represented by step 520. Specifically, the number of the vehicles inside the field station aggregated electronic fence is determined and a display number that corresponds to the determined number of vehicles displayed on at least one of the user and the dispatcher terminals. Specifically, the determination step of step 520 may be performed by the determining module 220 and the prompting step of step 520 may be performed by the displaying module 230.

When the terminal is a dispatcher terminal, subsequent authorization and prompting is represented by

steps

530 and 540. Specifically, in step 530, vehicle dispatching information based on the number of vehicles in the field station aggregated electronic fence is determined, for example, using the determination module 220, The vehicle dispatching information includes at least one of dispatch reminder, dispatch direction, number of vehicle to be dispatched, and dispatch navigation information the dispatcher terminal. In step 540, the vehicle dispatching information is then displayed on the dispatcher terminal, for example by the displaying module 230.

If the number of vehicles inside the field station electronic fence is less than a threshold number and the distance between the vehicle and the field station electronic fence is less than a second preset threshold distance, subsequent authorization and prompting is represented by step 550. Specifically, in step 550, navigation information for the vehicle to go inside the field station electronic fence is determined, for example by the determination module 220 and the navigation information is then displayed as an instructional content on at least one of user and dispatcher terminals, for example by the displaying module 230. The navigation information includes at least one of an entrance of the field station electrical fence and a routing information between vehicle and the entrance.

It should be noted that the above description of the process 500 is merely for the purpose of illustration and description, and does not limit the scope of application of this application. For those skilled in the art, various modifications and changes can be made to the process 500 under the guidance of the present disclosure. However, these amendments and changes are still within the scope of this application. For example, in step 530, when the display module 230 displays the navigation information of the vehicle's aggregated electronic fence at the field station, it can also broadcast a navigation voice prompt to remind the dispatcher.

More description about the boundary position information (geographical area boundary) of the field station aggregated electronic fence can be found elsewhere in this application (such as in the flow chart of FIG. 3 and its related description) and will not be repeated here. In some embodiments, the location relationship between the vehicle and the field station aggregated electronic fence may include that the vehicle is located inside the field station aggregated electronic fence and the vehicle is located outside the field station aggregated electronic fence. In some embodiments, a vehicle that is less than a preset distance from the field station aggregated fence may be considered a vehicle located within the field station aggregated fence. In some embodiments, the preset distance may be 200 meters, 300 meters, or 400 meters. In some embodiments, the determination module 220 may determine the relative positional relationship between the vehicle and the field station aggregated electronic fence according to the GPS data point of the vehicle and the boundary position information of the field station aggregated electronic fence.

In some embodiments, the navigation information of the vehicles arriving at a field station aggregated electronic fence may be displayed on a terminal based on the relative positional relationship and the number of vehicles in the field station aggregated electronic fence. Specifically, this step may be performed by the display module 230.

In some embodiments, in response to the number of vehicles in the field station aggregated electronic fence being less than a preset threshold, and the distance between the vehicle and the field station aggregated electronic fence is less than the second preset distance threshold, the display module 230 can display navigation information for the vehicle to arrive at the field station aggregated electronic fence.

In some embodiments, the preset threshold for the number of vehicles may be set artificially in advance according to a certain scenario, for example, population density, weather, holidays, etc. For example, the preset threshold for the number of vehicles may be 5 or 10. In some embodiments, the second preset distance threshold may be set artificially in advance. For example, the second preset distance threshold may be 1000 meters. For example, as shown in FIG. 7, if the current number of vehicles in the field station aggregated electronic fence 720-2 is 7 and the distance between the field station aggregated electronic fence 720-1 and the field station aggregated electronic fence 720-2 is less than 1000 meters, the navigation information from 720-2 to 720-1 is displayed as dotted line 750.

In some embodiments, the navigation information may include one or two of the entrance of the parking electronic fence and the driving path corresponding to the field station aggregated electronic fence. For example, as shown in FIG. 7, the navigation information of the vehicle to be dispatched from the field station aggregated electronic fence 720-2 to the field station aggregated electronic fence 720-1 includes the entrance 740-1 and driving path 750 of the parking electronic fence 730-1. According to the above navigation information, the vehicle dispatcher can accurately position the vehicle and dispatch the vehicle to the designated field station aggregated electronic fence. Through the navigation information on the dispatch terminal, dispatchers can order vehicles in order to ensure that a sufficient number of vehicles are available for users.

In some alternative embodiments, if the vehicle is a vehicle to be returned, based on the relative positional relationship between the vehicle and field station aggregated electronic fences and the number of vehicles in the field station aggregated electronic fences, a navigation information may be displayed on the user terminal to direct the vehicle to go to one of the field station electronic fences. The automatic prompting of the navigation information provides convenience for the renter to return the car with the renter playing an assistance function for dispatching the vehicle. In some embodiments, the relative positional relationship between the vehicle and the field station aggregated electronic fence may include that the vehicle is located within a safety fence and outside all the field station aggregated electronic fences, or the vehicle is located within another field station aggregated electronic fence. For example, as shown in FIG. 7, if the vehicle to be returned is vehicle C, the current number of vehicles in the field station aggregated electronic fence 1 does not meet the demand for the vehicle (such as 5 vehicles) , and the distance from the vehicle C to the field station aggregated electronic fence 720-1 is less than 1000 meters. Because the current number of vehicles in the field station aggregated electronic fence 720-2 is 7 thus has met the 5 vehicle demand, navigation information of the vehicle C arriving at the field station aggregated electronic fence 720-1 can be displayed to guide the user to return the vehicle to the field station aggregated electronic fences 720-1 to meet their vehicle needs. As another example, as shown in FIG. 7, if the vehicle to be returned is vehicle D, the current number of vehicles in the field station aggregated electronic fence 720-1 does not meet the demand for use of the vehicle (such as 5 vehicles) , and the distance from the D vehicle to the field station aggregated electronic fence 720-1 Less than 1000 meters. Because the current number of vehicles in the field station aggregated electronic fence 720-2 is 7 thus has met the 5 vehicle demand, then navigation information of the vehicle D arriving at the field station aggregated electronic fence 720-1 can be displayed to guide the user to return the vehicle to the field station aggregated fence 720-1 to meet their car use needs.

The methods and system disclosed herein provide many advantages over existing technology, including (1) by creating a virtual electronic fence, users can be guided to use and return cars in an orderly manner, thereby reducing labor operating costs; (2) Electronic fences and car use requirements can guide dispatchers to reasonably dispatch vehicles and meet users'car use needs.
