[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Before further describing the embodiments of the present invention in detail, the nouns and terms involved in the embodiments of the present invention are described. The nouns and terms involved in the embodiments of the present invention are applicable to the following interpretations:

[0041] Mobile APP: An APP independently developed by the OEM and built into each mobile phone. In this disclosure, it is mainly used for information exchange with charging piles and the car manufacturer's TSP platform.

[0042] Car manufacturer's Internet of Vehicles TSP platform: The Internet of Vehicles cloud platform developed by the OEM occupies a core position in the Internet of Vehicles industry chain. In this disclosure, its main responsibility is to interact with the mobile phone APP and provide relevant information required by the vehicle and charging pile.

[0043] Vehicle Bluetooth module: A module based on low-power Bluetooth communication installed inside the vehicle. It can communicate and interact with charging piles and mobile phone apps through Bluetooth technology, and can communicate and interact with the body domain controller in the vehicle through CAN communication.

[0044] Body domain controller: A domain controller installed inside the vehicle to control various modules of the body. In this disclosure, it is mainly used to receive command messages from the Bluetooth module and drive the charging port cover to execute commands.

[0045] Reference Figure 1 to Figure 2 As shown, a method for automatically controlling a charging port cover of an electric vehicle is applied to a charging pile, wherein the electric vehicle can be a new energy vehicle, such as a pure electric vehicle, a plug-in hybrid electric vehicle, a fuel cell electric vehicle, etc. The method specifically comprises the following steps:

[0046] S1. In response to a connection request initiated by a mobile terminal, obtain authentication information sent by the mobile terminal, perform security verification, and bind the mobile terminal;

[0047] Specifically, the authentication information includes: an authentication request and a first authorization code; wherein the first authorization code is obtained by the mobile terminal from the vehicle manufacturer's vehicle networking TSP platform. The first authorization code is a string of numbers generated in a fixed format, for example: EE1F1120A3ADF86C45B25059A8D1A923.

[0048] Further, obtaining the authentication information sent by the mobile terminal, performing security verification, and binding the mobile terminal include:

[0049] S11, obtaining an authentication request and a first authorization code sent by a mobile terminal;

[0050] S12: Compare the first authorization code with the preset second authorization code. If the comparison is successful, the binding with the mobile terminal is completed.

[0051] As a preferred embodiment of the present disclosure, the method also includes: if the charging pile is not preset with the second authorization code, the charging pile will prompt the user to perform a verification within a preset time, and obtain the second authorization code after the verification is completed. Exemplarily, the verification process is: if the charging pile is not preset with the second authorization code, the charging pile will prompt "Please swipe the charging card", and the user will take the charging card that matches the charging pile to perform a unique card swipe verification (the charging card and the charging pile are one-to-one corresponding). At this time, if the user does not swipe the card, the process will exit after the timeout (the timeout time can be set manually). If the card swiping is executed, the charging pile sends the mobile terminal the status information "the user has swiped the card", and the mobile terminal will resend the second authorization code to the charging pile for comparison, and the charging pile will write the received second authorization code into the internal storage space.

[0052] It should be further explained that the mobile terminal can be hardware or software. When the mobile terminal is hardware, it can be various electronic devices with a display screen and supporting communication with the background server and the car, such as: smart wearable devices, mobile phones, tablet computers, vehicle-mounted terminals, laptop portable computers and desktop computers, etc.; when the mobile terminal is software, it can be installed in the above electronic devices. The mobile terminal can be implemented as multiple software or software modules, or as a single software or software module, and the present disclosure does not limit this. Furthermore, various applications (APPs) can be installed on the mobile terminal, such as: applet applications, charging pile applications, etc.

[0053] The mobile terminal initiates a connection request, including: the mobile terminal searches and identifies a specific charging pile through wireless communication technology (such as Bluetooth, Wi-Fi, NFC, etc.). For example, the user clicks on the "My Charging Pile" icon interface in the car manufacturer's mobile phone APP, and the mobile phone APP drives the bottom layer of the mobile phone to start scanning surrounding Bluetooth devices, and locks the Bluetooth devices that need to be connected through the internal whitelist and displays them in the mobile phone APP. At this time, the mobile phone APP first determines whether the Bluetooth device is a Bluetooth device that has been connected locally before. If not, it prompts the user to "please connect Bluetooth manually", and the user clicks the Bluetooth connection icon on the APP.

[0054] By performing security verification between the mobile terminal and the charging pile, the security and legality of each connection are ensured, and connection errors can be prevented, the target vehicle can be correctly identified, and the opening and closing of the charging port cover can be accurately controlled. This can prevent the problem of being unable to control the opening and closing of the charging port cover due to connection errors or identification failures.

[0055] S2, receiving vehicle identification information and verification credentials sent by the mobile terminal;

[0056] The vehicle identification information is used to uniquely identify a specific vehicle, and the verification certificate is used to confirm the identity and authority of the vehicle.

[0057] S3, searching for a target vehicle corresponding to the vehicle identification information within a preset range, and binding the target vehicle based on the verification credential;

[0058] Specifically, the vehicle identification information is the vehicle Bluetooth Mac address, and the verification credential is the authentication key, which is a key generated by the vehicle VIN code and the vehicle Bluetooth Mac address. The vehicle Bluetooth Mac address and vehicle VIN code are obtained by the mobile terminal from the vehicle manufacturer's Internet of Vehicles TSP platform.

[0059] As a preferred embodiment of the present disclosure, binding a target vehicle based on verification credentials includes: sending an authentication key to the target vehicle so that the target vehicle decrypts the authentication key and compares and verifies it with a preset key to complete the binding of the charging pile and the vehicle.

[0060] As a preferred embodiment of the present disclosure, the method further includes: after binding the target vehicle, saving the vehicle VIN code and the vehicle Bluetooth Mac address.

[0061] Exemplarily, the mobile phone APP sends the vehicle VIN code, vehicle Bluetooth Mac address and authentication key required for the Bluetooth connection between the charging pile and the vehicle to the charging pile. When the vehicle is close to the charging pile (i.e. within the Bluetooth connection range), the charging pile actively scans the surrounding Bluetooth devices. After scanning the vehicle Bluetooth MAC address, it starts to send the authentication key. After the vehicle-side Bluetooth module receives the authentication key (the key generated by the vehicle VIN code and the vehicle Bluetooth MAC address), it decrypts it and compares it with the key preset in the module. If it is inconsistent, the process is exited. If it is consistent, the binding of the charging pile and the vehicle is completed. After the binding is completed, the charging pile sends the binding completion information to the mobile phone APP. The mobile phone APP saves the vehicle VIN code and the vehicle Bluetooth MAC address so that the next time the mobile phone connects to the pile, it can automatically connect to the charging pile directly by matching the local cached Bluetooth device identifier.

[0062] Reference Figure 3 As shown, S4, the plugging and unplugging status of the charging gun is obtained according to the user's plugging and unplugging action, and the plugging and unplugging status is sent to the target vehicle, so that the target vehicle controls the opening and closing of the charging port cover based on the plugging and unplugging status.

[0063] Specifically, the target vehicle controls the opening and closing of the charging port cover based on the plug-in status. The target vehicle sends corresponding instructions to the vehicle Bluetooth module based on the plug-in status. The vehicle Bluetooth module is used to convert the instructions into CAN signals and send them to the body domain controller, so that the body domain controller controls the opening and closing of the charging port cover of the target vehicle.

[0064] Exemplary, the process of automatic opening of the charging port cover when the charging gun is pulled out of the charging pile: After the charging pile and the vehicle are bound, the user presses the handle button of the charging gun in the charging pile to pull out the charging gun. At this time, the charging pile detects that the charging gun has been pulled out, and the charging pile immediately sends a command message to open the vehicle charging port cover to the vehicle Bluetooth module. After the vehicle Bluetooth module receives it, it converts it into a CAN signal and sends it to the body domain controller. The body domain controller then drives the charging port cover to perform the automatic opening function, and the user plugs in the gun to charge. The process of automatic closing of the charging port cover when the charging pile is pulled out of the charging pile: After the user has finished charging, pull out the charging gun and put it back into the charging pile. When the charging pile detects that the charging gun has returned to its place, it immediately sends a command to close the charging port cover to the vehicle Bluetooth module. After receiving it, the vehicle Bluetooth module converts it into a CAN signal and sends it to the body domain controller. The body domain controller then drives the charging port cover to perform the automatic closing function, and the charging port cover automatically closes.

[0065] By binding the target vehicle to the charging pile and monitoring the plug-in status of the charging gun on the charging pile, the opening and closing of the charging port cover of the target vehicle is controlled by the plug-in status of the charging gun, which solves the inaccuracy problem caused by opening or closing the charging port cover in advance in the prior art and improves the user experience.

[0069] A target vehicle binding module, used to search for a target vehicle corresponding to the vehicle identification information within a preset range, and bind the target vehicle based on the verification credential;

[0070] The charging port cover control module is used to obtain the plugging and unplugging status of the charging gun according to the user's plugging and unplugging actions, and send the plugging and unplugging status to the target vehicle so that the target vehicle controls the opening and closing of the charging port cover based on the plugging and unplugging status.

[0072] Based on the same inventive concept, the present disclosure also proposes a computer-readable storage medium on which computer instructions are stored. When the computer instructions are executed, the above-mentioned automatic control method of the charging port cover of an electric vehicle can be implemented.
