[0002] When electric vehicles are charging, the server needs to record and settle electricity consumption based on the matching relationship between the charging station and the vehicle, thereby generating an order record fee for user payment. Currently, users need to scan the charging station's code using a handheld terminal application before the server can establish a matching relationship between the charging station and the vehicle. However, this charging method is rather cumbersome. If the user's handheld terminal malfunctions, the matching relationship between the charging station and the vehicle cannot be established, and the vehicle cannot be charged.

[0043] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0044] During electric vehicle charging, to record electricity consumption and settle fees, the charging server needs to accurately establish a binding relationship between the charging pile and the vehicle, thereby generating associated orders and calculating charging costs. Currently, the system requires users to use a dedicated application on a handheld device (such as a smartphone or tablet) to scan a QR code or barcode affixed to the surface of the charging pile before charging. This triggers the server's association of the charging pile number with the vehicle's identity. This charging method has significant limitations. Users must rely on a handheld device to complete the scanning operation. If the user's handheld device runs out of power, experiences a network connection interruption, camera malfunction, or application crashes, the scanning process will fail, preventing the server from recognizing the correspondence between the charging pile and the vehicle. Furthermore, environmental factors can interfere in actual operation, such as the charging pile QR code being dirty, reflective, or installed at too high, making recognition difficult. All these issues increase the complexity of the user's operation. In such scenarios, even if the vehicle is parked in a charging space and the charging gun is physically connected, the user still cannot use the charging service, ultimately preventing the user from charging their vehicle. Therefore, simplifying vehicle charging methods and eliminating the influence of handheld terminals and charging pile QR codes on the vehicle charging process has become a pressing problem for those skilled in the art. To address this issue, this application provides a control method for a vehicle charging system (such as...). Figure 1 (as shown), the control device 10 of the vehicle charging system (such as...) Figure 2 (as shown), electronic devices and computer program products 200 (such as) Figure 13 (As shown).

[0045] Please see Figure 1 as well as Figure 2 The control method for the vehicle charging system according to the embodiments of this application includes:

[0046] 05: Determine the vehicle-charging-station relationship based on the vehicle's parking location and the location of the charging station's charging port;

[0047] 07: Based on the vehicle-charging station relationship, control the target charging station to charge the vehicle.

[0048] The aforementioned control method for a vehicle charging system can be applied to a control device 10 for the vehicle charging system. The control device 10 of the vehicle charging system in this embodiment includes a determining module 11 and a control module 12. The determining module 11 executes step 05, and the control module 12 executes step 07. Specifically, the determining module 11 determines the vehicle-charging pile relationship between the vehicle and the target charging pile based on the vehicle's parking position and the position of the charging port when the vehicle enters the parking lot. The control module 12 controls the target charging pile to charge the vehicle based on the vehicle-charging pile relationship until the vehicle is fully charged.

[0049] Specifically, the control device 10 of the vehicle charging system is responsible for integrating the vehicle's parking location and the location of the charging station's plug in the parking lot, thereby automating and simplifying the vehicle charging service process. The control device 10 includes a determination module 11 and a control module 12. The determination module 11, after the vehicle enters the parking lot, determines a one-to-one match between the vehicle and the target charging station based on the vehicle's parking location and the location of the target charging station's plug, establishing a vehicle-charging station relationship. The control module 12, based on the vehicle-charging station relationship provided by the determination module 11, controls the target charging station to charge the vehicle until charging is complete, thus completing the user's vehicle charging operation.

[0050] More specifically, in step 05, "vehicle" refers to the user's vehicle that needs charging. "Vehicle entering the parking lot" means the user is driving an electric vehicle that needs charging into the parking lot. When the vehicle passes through the parking lot entrance gate, the vehicle charging system can confirm the vehicle's identity through license plate recognition or Bluetooth beacon to verify whether the vehicle can enter the parking lot. This step will be explained in more detail later. After the vehicle enters the parking lot, the user needs to continue driving the vehicle to find a parking space for charging. The vehicle's parking location refers to the parking space where the user parks the vehicle. The target charging station refers to the charging station the user uses to charge the vehicle. Each charging station has at least one charging port, and the position of the charging port also reflects the vehicle's location. Therefore, based on the vehicle's parking location and the position of the charging port at the target charging station, a one-to-one correspondence between the vehicle and the target charging station can be determined, i.e., the vehicle-charging station relationship. A more detailed process for establishing the vehicle-charging station relationship will be described in more detail below.

[0051] More specifically, in step 07, after the vehicle-charging pile relationship is determined, that is, after the one-to-one correspondence between the vehicle and the target charging pile is determined by the determination module 11, the control module 12 obtains the charging receiver, i.e., the vehicle, based on the vehicle-charging pile relationship. Therefore, the control module 12 can control the target charging pile to charge the vehicle until the vehicle is fully charged.

[0052] Furthermore, charging stations need to clearly identify the current charging service recipient (i.e., the user to whom the vehicle belongs) to link the user account and record electricity consumption. Without a matching relationship, the system cannot determine the attribution of electricity charges, leading to billing confusion (e.g., when multiple vehicles use the same charging station simultaneously, it's impossible to distinguish the responsible party). The matching relationship also verifies whether the user has charging permissions (e.g., sufficient account balance, VIP privileges, or enterprise whitelist), preventing unauthorized users from misusing the charging service. If the charging station is not bound to a vehicle, there may be risks of incorrect current output (the charging gun being inserted into an unauthorized vehicle or non-vehicle equipment (e.g., a metal object), causing a short circuit or electric shock risk) or multiple vehicles competing for the same charging station (without matching, multiple vehicles may attempt to use the same charging station simultaneously, causing power overload or equipment damage). Without a matching relationship, the charging station may also continue to supply power to vehicles that have already left (e.g., the user unplugs the charging gun but billing continues), or occupy the charging station without actually charging (e.g., the charging gun is plugged in but not activated), resulting in decreased resource utilization. The vehicle-charging station relationship records the interaction logs between the vehicle and the charging station (such as charging start and end times, abnormal events), which facilitates fault location (for example, distinguishing whether the charging station failure or the vehicle BMS communication problem is the cause of the charging interruption).

[0053] It is understood that this application provides a control method for a vehicle charging system. The vehicle's parking position reflects its location, and the position of the charging pile's plug reflects the location of the object being charged. Therefore, when a vehicle enters a parking lot, a vehicle-charging pile relationship can be established based on the vehicle's parking position and the charging pile's plug position. Then, based on this relationship, the charging pile is controlled to charge the vehicle, thus completing the charging process. This application eliminates the need for the vehicle owner to carry a handheld terminal, simplifying the charging method and improving the convenience of vehicle charging.

[0054] In some implementations, please refer to Figure 2 and Figure 3 05: Based on the vehicle's parking location and the location of the target charging station's charging port, determine the vehicle-charging station relationship, including:

[0055] 055: Based on the parking location, determine the vehicle-parking space relationship between the vehicle and the target parking space, where the parking location includes the location of the target parking space;

[0056] 057: Determine the vehicle-charging station relationship based on the vehicle-parking space relationship and the location of the charging station's charging port.

[0057] The above-mentioned control method for the vehicle charging system can be applied to the control device 10 of the vehicle charging system. The determination module 11 is used to determine the vehicle-parking space relationship between the vehicle and the target parking space based on the parking position, where the parking position includes the position of the target parking space; and to determine the vehicle-charging pile relationship based on the vehicle-parking space relationship and the position of the charging gun of the target charging pile.

[0058] Specifically, when an electric vehicle waiting to be charged enters a parking lot, the system first needs to determine the vehicle's exact parking location. This can be achieved in several ways, such as using a geomagnetic sensor to detect the vehicle entering the parking space, or using a camera to capture the process of the vehicle parking and then using image recognition technology to confirm the vehicle's position.

[0059] Specifically, after a vehicle enters a parking space, a one-to-one correspondence between the vehicle and the target parking space (the parking space where the vehicle is parked) can be determined based on the vehicle's parking position. Then, based on the location of the charging port of the target charging station (the charging station that will charge the vehicle), the location of the target charging object is determined, thus establishing a one-to-one correspondence between the charging port of the target charging station and the target parking space. Furthermore, based on the vehicle-parking space relationship (using the target parking space as a medium, there is a matching relationship between the target charging station and the target parking space, and also between the target parking space and the vehicle), the vehicle-charging station relationship (a one-to-one matching relationship between the target charging station and the vehicle) is determined.

[0060] Please see Figure 2 and Figure 4 In some implementations, 057: Determining the vehicle-charging station relationship based on the vehicle-parking space relationship and the location of the charging station's charging port includes:

[0061] 0571: Based on the target charging station's number, obtain the location of the target charging station, the starting position of the target charging station's charging port, and the color of the charging port's charging wire.

[0062] 0573: Based on the image information of the target charging pile, the location of the target charging pile, the starting position of the charging gun of the target charging pile, and the color of the charging gun wire of the target charging pile, determine the charging pile-parking space relationship between the target charging pile and the target parking space. The image information of the target charging pile includes the image information of the target parking space.

[0063] 0575: Determine the vehicle-charging station relationship based on the vehicle-parking space relationship and the charging station-parking space relationship.

[0064] The control method of the above-mentioned vehicle charging system can be applied to the control device 10 of the vehicle charging system. The determining module 11 is used to obtain the location of the target charging pile, the starting position of the charging gun of the target charging pile, and the color of the charging gun wire of the target charging pile according to the number of the target charging pile; determine the charging pile-parking space relationship between the target charging pile and the target parking space according to the image information of the target charging pile, the location of the target charging pile, the starting position of the charging gun of the target charging pile, and the color of the charging gun wire of the target charging pile; the image information of the target charging pile includes the image information of the target parking space; and determine the vehicle-charging pile relationship according to the vehicle-parking space relationship and the charging pile-parking space relationship.

[0065] Specifically, the charging pile number is a unique identifier for each charging pile. This number is used to associate the charging pile's physical attributes and status information. Therefore, the location of the target charging pile, the starting position of its charging port, and the color of the charging port's wires can be obtained based on the target charging pile's number. The starting position of the charging port refers to its location before the user moves it. The color of the charging port's wires refers to the color of the connecting wires between the charging port and the charging pile. The method for setting the wire colors will be described in detail below.

[0066] Specifically, the image information of the target charging station refers to the image captured by the parking space camera, which includes both the vehicle and the target charging station. Therefore, based on the image information of the target charging station, its location, the starting position of its charging port, and the color of its charging port wires, the charging station-parking space relationship can be determined. Furthermore, based on the charging station-parking space relationship and the vehicle-parking space relationship, the vehicle-charging station relationship can be determined. This process will be explained in detail below.

[0067] In some implementations, please refer to Figure 2 and Figure 5 0573: Based on the image information of the target charging station, its location, the starting position of its charging port, and the color of its charging port wires, determine the charging station-parking space relationship between the target charging station and the target parking space, including:

[0068] 05731: Based on the image information of the target charging station, the location of the target charging station, and the starting position of the charging station's charging port, determine the image information of the transition parking space. The image information of the transition parking space includes the image information of all parking spaces that the charging station's charging port can reach, and the transition parking space includes the target parking space.

[0069] 05733: Based on the image information of the transition parking space, determine the position information of the transition plugs in the image information of the transition parking space. The position information of the transition plugs includes the position of the plug head and the direction of the plug in the image information of the transition parking space.

[0070] 05735: Determine the charging pile-parking space relationship between the target charging pile and the target parking space based on the color of the charging gun's wires and the location information of the transition charging gun.

[0071] The above-mentioned control method for the vehicle charging system can be applied to the control device 10 of the vehicle charging system. The determining module 11 is used to determine the image information of the transition parking space based on the image information of the target charging pile, the location of the target charging pile, and the starting position of the charging gun of the target charging pile. The image information of the transition parking space includes the image information of all parking spaces that can be reached by the charging gun of the target charging pile, and the transition parking space includes the target parking space. Based on the image information of the transition parking space, the position information of the transition charging gun in the image information of the transition parking space is determined. The position information of the transition charging gun includes the position of the gun head and the direction of the charging gun in the image information of the transition parking space. Based on the color of the charging wire of the charging gun of the target charging pile and the position information of the transition charging gun, the charging pile-parking space relationship between the target charging pile and the target parking space is determined.

[0072] Specifically, transitional parking spaces refer to all parking spaces that the charging station's outlet can reach. For example, suppose a parking lot only has a row of parking spaces arranged side-by-side in an east-west direction. If the charging station's outlet extends fully east or west, and its coverage area only reaches three parking spaces near the charging station, then the transitional parking spaces are these three parking spaces in the example above. Since users need to use the charging station's outlet to charge their vehicles, the transitional parking spaces include the target parking spaces.

[0073] Specifically, based on the image information of the transition parking space, the position information of the transition charging guns in the image information of the transition parking space is determined. The position information of the transition charging guns includes the position of the gun head and the direction of the gun in the image information of the transition parking space. Both the position of the gun head and the direction of the gun can be used in the image processing recognition process to accurately determine the position of the charging gun. Based on the color of the charging wire of the target charging pile and the position information of the transition charging gun, the determining module 11 can determine the charging pile-parking space relationship between the target charging pile and the target parking space. This process will be explained in more detail below.

[0074] In some implementations, please refer to Figure 2 as well as Figure 6 05733: Based on the image information of the transition parking space, determine the location information of the transition parking gun in the image information of the transition parking space, including:

[0075] 057331: Based on the image information of the transition parking space, determine the separation boundary and number of the transition parking space;

[0076] 057333: Based on the preset object detection algorithm, determine the position information of the transition guns in the image information of the transition parking space. The position information of the transition guns includes the position of the gun head and the direction of the gun in the image information of the transition parking space.

[0077] The control method of the above-mentioned vehicle charging system can be applied to the control device 10 of the vehicle charging system. The determining module 11 is used to determine the separation boundary and number of the transition parking space according to the image information of the transition parking space; and to determine the position information of the transition plug in the image information of the transition parking space according to the preset object detection algorithm. The position information of the transition plug includes the position of the plug head and the plug direction of all plugs in the image information of the transition parking space.

[0078] Specifically, the determining module 11 determines the separation boundary and number of the transition parking space based on the image information of the transition parking space. The separation boundary helps to distinguish the boundaries between transition parking spaces, and the number of the transition parking space can be used to establish a correspondence later. The determining module 11 can determine the position information of the transition guns in the image information of the transition parking space according to a preset object detection algorithm (computer vision-based object detection technology, which can locate the position of the guns in the image). The position information of the transition guns includes the position of the gun head and the direction of the guns in the image information of the transition parking space.

[0079] In some implementations, please refer to Figure 2 and Figure 7 05735: Based on the color of the charging port's wires and the location information of the transition charging port, determine the charging station-parking space relationship between the target charging station and the target parking space, including:

[0080] 057351: Based on the color of the charging port wire and the position information of the transition charging port, determine the position information of the charging port. The position information of the charging port includes the position of the charging port head and the charging port direction.

[0081] 057353: Determine the charging pile-parking space relationship between the target charging pile and the target parking space based on the location information of the charging gun of the target charging pile, the separation boundary of the transition parking space, and the number of the transition parking space.

[0082] The control method of the above-mentioned vehicle charging system can be applied to the control device 10 of the vehicle charging system. The determining module 11 is used to: determine the position information of the target charging pile's plug according to the color of the plug wire of the target charging pile and the position information of the transition plug, the position information of the target charging pile's plug includes the position of the plug head and the plug direction; and determine the charging pile-parking space relationship between the target charging pile and the target parking space according to the position information of the target charging pile's plug, the separation boundary of the transition parking space and the number of the transition parking space.

[0083] Specifically, each charging station's charging port is assigned a unique color identifier (such as red or blue) to visually distinguish the charging ports of different charging stations. This color information is typically stored in a database and linked to the charging station's number. The determining module 11 can determine the location information of the target charging station's charging port based on the color of its charging port and the location information of the transition charging port. Furthermore, based on the location information of the target charging station's charging port, the boundary of the transition parking space, and the number of the transition parking space, it can determine the charging station-parking space relationship between the target charging station and the target parking space.

[0084] In some implementations, please refer to Figure 8 and Figure 9 07: Based on the vehicle-charging station relationship, the control method for controlling the charging station to charge the vehicle until the vehicle is fully charged also includes:

[0085] 06: When the charging station's charging gun is plugged into the vehicle, upload the plugged-in information to the charging station, which includes the target charging station's number.

[0086] The above-mentioned control method for the vehicle charging system can be applied to the control device 10 of the vehicle charging system. The control device 10 of the vehicle charging system also includes an upload module 13. The upload module 13 is used to upload the plug-in information to the charging pile when the charging pile plug is inserted into the vehicle. The plug-in information includes the number of the target charging pile.

[0087] Specifically, inserting the charging gun into the vehicle refers to the user inserting the charging station's charging gun into the electric vehicle's charging port. The gun head is physically connected to the vehicle's charging port, thus establishing a charging path. When the charging station's charging gun is inserted into the vehicle, sensors inside the charging station (such as position sensors or current sensors) detect the insertion and confirm the connection status between the charging gun and the vehicle's charging port, ensuring that the charging gun is correctly and safely connected to the vehicle. The inserted gun information includes the target charging station's number, which is used in the subsequent matching process.

[0088] In some implementations, please refer to Figure 8 and Figure 9 The control methods also include:

[0089] 01: Determine the color of the charging gun wires based on the location of all charging piles, the length of the charging gun wires, and the location of all parking spaces.

[0090] The above-mentioned control method for the vehicle charging system can be applied to the control device 10 of the vehicle charging system. The control device 10 of the vehicle charging system also includes a color determination module 14, which is used to determine the color of the charging gun wire of the charging pile according to the location of all charging piles, the length of the charging gun wire, and the location of all parking spaces.

[0091] Understandably, the color of the gun line also needs to be set and determined in advance for the matching process. The method for determining the gun line color will be explained in detail below.

[0092] In some implementations, please refer to Figure 9 and Figure 10 01: Based on the location of all charging piles, the length of the charging cable, and the location of all parking spaces, determine the color of the charging pile's charging cable connector, including:

[0093] 011: Select any one charging station from all charging stations. Based on the location of the charging station and the length of the charging cable, determine the accessible parking spaces that the charging station's charging cable can reach from all parking spaces.

[0094] 013: Based on the location of all charging piles and the length of the charging cables, determine the accessible charging ports that can be accessed for each accessible parking space, and assign a different cable color to each accessible charging port that does not have a cable color set.

[0095] 015: Repeat the steps of determining the accessible parking spaces that the charging station's plug can reach from all parking spaces based on the location of the charging station and the length of the charging cable, to determining the accessible plug that each accessible parking space can reach based on the location of all charging stations and the length of the charging cable, and assigning a different wire color to each accessible plug that has not been assigned a wire color, until the plug of each charging station is assigned a wire color.

[0096] The control method of the above-mentioned vehicle charging system can be applied to the control device 10 of the vehicle charging system. The color determination module 14 is used to select any one charging pile from all charging piles, and determine the accessible parking spaces that the charging pile's plug can reach from all parking spaces according to the location of the charging pile and the length of the charging cable; determine the accessible plugs that can be reached by each accessible parking space according to the location of all charging piles and the length of the charging cable, and set a different wire color for each accessible plug that has not been set with a wire color; repeat the steps of determining the accessible parking spaces that the charging pile's plug can reach from all parking spaces according to the location of the charging pile and the length of the charging cable, and determining the accessible plugs that can be reached by each accessible parking space according to the location of all charging piles and the length of the charging cable, and setting a different wire color for each accessible plug that has not been set with a wire color, until the plugs of each charging pile are set with a wire color.

[0097] Specifically, the color determination module 14 is used to select any one charging pile from all charging piles, and determine the accessible parking spaces that the charging pile's charging port can reach from all parking spaces based on the location of the charging pile and the length of the charging cable. Then, based on the location of all charging piles and the length of the charging cable, it determines the accessible charging ports that each accessible parking space can reach, and assigns a different cable color to each accessible charging port that does not have a assigned cable color; this process is repeated until all charging pile charging ports have assigned a cable color. For example, in a parking lot, select a charging gun, denoted as charging gun B1. Using the end of the charging gun's wire (the connection point between the wire and the parking post) as the center point and the wire length as the radius, calculate all parking spaces that charging gun B1 can normally reach (accessible parking spaces), denoted as set P. For a parking space p in set P, calculate all charging guns that parking space p can normally reach, denoted as pB, and add pB to set H. Iterate through all parking spaces in set P in this way to obtain a charging gun set H. Assign a wire color to all uncolored charging guns in set H, ensuring the wire color is different from the already colored charging guns in the set. Select the next uncolored charging gun and repeat the above operation until all charging guns in the parking lot have been assigned a wire color.

[0098] In some implementations, please refer to Figure 8 and Figure 9 The control methods also include:

[0099] 02: Obtain user information and vehicle information of preset vehicles, and determine the preset matching relationship between users and preset vehicles.

[0100] The above-mentioned control method for the vehicle charging system can be applied to the control device 10 of the vehicle charging system. The control device 10 of the vehicle charging system also includes a preset relationship determination module 15. The preset relationship determination module 15 is used to obtain user information and vehicle information of preset vehicles, and determine the preset matching relationship between the user and the preset vehicle.

[0101] Understandably, parking lot gates need to determine whether to open the gate and allow vehicles to enter based on user identity information. Therefore, after acquiring vehicle information (such as license plate number), the gate camera needs to determine whether to allow the vehicle to enter the parking lot based on the matching relationship between the user and the vehicle. Thus, users can register before entering the parking lot to establish a pre-defined matching relationship between user identity information and vehicles.

[0102] In some implementations, please refer to Figure 8 and Figure 9 The control methods also include:

[0103] 031: Determine whether a vehicle meets the conditions for entering the parking lot based on the preset matching relationship between the user and the preset vehicle;

[0104] 032: If the vehicle meets the conditions for entering the parking lot, open the parking lot gate.

[0105] The above-mentioned control method for the vehicle charging system can be applied to the control device 10 of the vehicle charging system. The control device 10 of the vehicle charging system also includes a barrier gate control module 16. The barrier gate control module 16 is used to determine whether the vehicle meets the conditions for entering the parking lot based on the preset matching relationship between the user and the preset vehicle; and to open the barrier gate of the parking lot if the vehicle meets the conditions for entering the parking lot.

[0106] Understandably, the barrier gate control module 16 queries the user identity information corresponding to the vehicle based on a preset matching relationship. If the user has registered their identity information and a preset matching relationship (a one-to-one correspondence between the user and the vehicle) has been formed, then the barrier gate control module 16 can open the barrier gate. If no user corresponds to the vehicle, it indicates that the user has not yet registered, and in this case, the barrier gate control module 16 can remind the user to register.

[0107] In some implementations, please refer to Figure 8 , Figure 11 and Figure 12 The system includes a barrier camera 191, which is installed at the barrier gate of the parking lot. 031: Based on a preset matching relationship between the user and a preset vehicle, the system determines whether a vehicle meets the conditions for entering the parking lot, including:

[0108] 0311: Based on the preset matching relationship and the vehicle information captured by the barrier gate camera 191, determine whether there is a matching user for the vehicle. The barrier gate camera is used to obtain the vehicle information.

[0109] 0313: If a matching user exists for the vehicle, determine if the vehicle meets the conditions for entering the parking lot;

[0110] 0315: If no matching user exists for the vehicle, determine that the vehicle does not meet the conditions for entering the parking lot.

[0111] The control method of the above-mentioned vehicle charging system can be applied to the control device 10 of the vehicle charging system. The barrier gate control module 16 is used to determine whether there is a matching user for the vehicle based on the preset matching relationship and the vehicle information. The barrier gate camera 191 is used to acquire the vehicle information. If there is a matching user for the vehicle, it is determined that the vehicle meets the conditions for entering the parking lot. If there is no matching user for the vehicle, it is determined that the vehicle does not meet the conditions for entering the parking lot.

[0112] Understandably, when a vehicle has a matching user—that is, when the user has completed registration and payment can be directly deducted based on their personal information—the gate control module 16 determines that the vehicle meets the conditions for entering the parking lot. However, when a vehicle does not have a matching user—that is, when the user has not completed registration and payment cannot be directly deducted based on their personal information—the gate control module 16 determines that the vehicle does not meet the conditions for entering the parking lot.

[0113] In some implementations, please refer to Figure 8 , Figure 9 and Figure 12 The vehicle charging system includes a road camera 192 and a parking space camera 193. The road camera 192 covers all roads within the parking lot, and the parking space camera 193 is spaced apart on top of different parking spaces, covering multiple parking spaces. 05: Before determining the vehicle-charging station relationship based on the vehicle's parking position and the charging station's plug position, the control method also includes:

[0114] 041: Determine the vehicle's trajectory based on the vehicle image information captured by the road camera 192 and the parking space camera 193;

[0115] 043: Determine the vehicle's parking location based on the driving trajectory.

[0116] The control method of the above-mentioned vehicle charging system can be applied to the control device 10 of the vehicle charging system. The control device 10 of the vehicle charging system also includes a position determination module 17. The position determination module 17 is used to determine the driving trajectory of the vehicle based on the vehicle image information captured by the road camera 192 and the parking space camera 193; and to determine the parking position of the vehicle based on the driving trajectory.

[0117] Specifically, the barrier gate camera 191, road camera 192, and parking space camera 193 used in this invention are all rotatable cameras, thereby further reducing the number of cameras in the parking lot. Road camera 192 and parking space camera 193 (for example, Figure 12 The dashed box covering the parking space indicates the coverage area of ​​the parking space camera 193. It can capture vehicle image information so that the location determination module 17 can obtain the vehicle's driving trajectory based on the image information, and then determine the vehicle's parking position based on the driving trajectory.

[0118] In some implementations, please refer to Figure 8 and Figure 9 The control methods also include:

[0119] 08: Generate a charging order based on the vehicle-charging station relationship;

[0120] 09: Once the vehicle has finished charging, deduct the payment from the user associated with the vehicle based on the charging order.

[0121] The above-mentioned control method for the vehicle charging system can be applied to the control device 10 of the vehicle charging system. The control device 10 of the vehicle charging system also includes a deduction module 18, which is used to generate a charging order based on the vehicle-charging pile relationship; and deduct payment from the user matched with the vehicle based on the charging order when the vehicle has finished charging.

[0122] Understandably, the payment module 18 can generate a charging order based on the vehicle-charging station relationship, and each charging order corresponds to a vehicle. After the vehicle completes charging, the payment module 18 can deduct the payment from the user based on the user's identity information corresponding to the vehicle, thus achieving seamless payment.

[0123] In summary, this application provides a control method for a vehicle charging system. The vehicle's parking position reflects its location, and the position of the charging pile's charging port reflects the location of the object being charged. Therefore, when a vehicle enters a parking lot, a vehicle-charging pile relationship can be established based on the vehicle's parking position and the charging pile's charging port position. Then, based on this relationship, the charging pile can be controlled to charge the vehicle, thus completing the charging process. This application eliminates the need for the vehicle owner to carry a handheld terminal, simplifying the charging method and improving the convenience of vehicle charging.

[0124] In some embodiments, this application also provides a vehicle charging system, which includes a barrier gate camera, a road camera, a parking space camera, and a control device for the vehicle charging system of claim 15. The barrier gate camera is installed at the barrier gate of the parking lot. The road camera's field of view covers all roads within the parking lot.

[0128] 07: Based on the vehicle-charging station relationship, control the target charging station to charge the vehicle.

[0129] For example, when the processor of an electronic device executes a computer program stored in memory, it implements the following control methods:

[0130] 055: Based on the parking location, determine the vehicle-parking space relationship between the vehicle and the target parking space, where the parking location includes the location of the target parking space;

[0131] 057: Determine the vehicle-charging station relationship based on the vehicle-parking space relationship and the location of the charging station's charging port.

[0132] For example, when the processor of an electronic device executes a computer program stored in its memory, it can also implement the control methods in 01, 011, 013, 015, 02, 031, 0311, 0313, 0315, 032, 041, 043, 0571, 0573, 05731, 05733, 057331, 057333, 05735, 057351, 057353, 0575, 06, 08, and 09.

[0135] 05: Determine the vehicle-charging-station relationship based on the vehicle's parking location and the location of the charging station's charging port;

[0136] 07: Based on the vehicle-charging station relationship, control the target charging station to charge the vehicle.

[0138] 055: Based on the parking location, determine the vehicle-parking space relationship between the vehicle and the target parking space, where the parking location includes the location of the target parking space;

[0139] 057: Determine the vehicle-charging station relationship based on the vehicle-parking space relationship and the location of the charging station's charging port.

[0140] For example, when computer program 202 is executed by processor 20, it can also implement the control methods in 01, 011, 013, 015, 02, 031, 0311, 0313, 0315, 032, 041, 043, 0571, 0573, 05731, 05733, 057331, 057333, 05735, 057351, 057353, 0575, 06, 08, and 09.

[0141] In the computer program product 200 of this application, the vehicle's parking position reflects the vehicle's location, and the position of the charging pile's charging port reflects the location of the object being charged. Therefore, when a vehicle enters a parking lot, a vehicle-charging pile relationship can be established based on the vehicle's parking position and the charging pile's charging port position. Then, based on this relationship, the charging pile is controlled to charge the vehicle, thus completing the charging process. This application eliminates the need for the vehicle owner to carry a handheld terminal, simplifying the charging method and improving the convenience of vehicle charging.
