Description

Technical Field

[0001] This invention belongs to the field of automotive control technology, and specifically relates to an automatic control method and system for electric vehicle charging port covers. Background Technology

[0002] With the rapid development of new energy vehicles and intelligent connected vehicle technologies, the intelligence and convenience of automobiles have become crucial factors in attracting consumers. Precise scenario-based intelligence is the main direction for future development, especially in high-frequency, essential charging scenarios, where providing a more intelligent and convenient user experience is paramount. However, most automakers still fall short in terms of charging experience.

[0003] Currently, most new energy vehicles on the market require users to manually open the charging port cover, insert the charging gun, and then manually close the cover again after charging is complete. This process is cumbersome and inconvenient. To solve this problem, existing technologies detect the vehicle's battery level and automatically control the charging port cover via remote commands. However, this often results in the charging port cover opening or closing prematurely, failing to precisely control the opening and closing based on the actual time the user inserts and removes the charging gun, thus failing to fully realize the advantages of intelligent features in new energy vehicles. Summary of the Invention

[0004] To address the problems in the background art, this invention proposes an automatic control method and system for electric vehicle charging port covers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Firstly, this disclosure proposes an automatic control method for an electric vehicle charging port cover, comprising:

[0008] Receive vehicle identification information and verification credentials sent by the mobile terminal;

[0009] Search for target vehicles corresponding to the vehicle identification information within a preset range, and bind the target vehicles based on the verification credentials;

[0010] The user's plugging and unplugging actions are used to obtain the plugging and unplugging status of the charging gun, and the plugging and unplugging status is sent to the target vehicle so that the target vehicle can control the opening and closing of the charging port cover based on the plugging and unplugging status.

[0011] Preferably, the authentication information includes: an authentication request and a first authorization code;

[0012] The step of obtaining authentication information sent by the mobile terminal, performing security verification, and binding the mobile terminal includes:

[0013] Obtain the authentication request and first authorization code sent by the mobile terminal;

[0014] The first authorization code is compared with the preset second authorization code. If the comparison is successful, the binding with the mobile terminal is completed.

[0015] Preferably, the method further includes: if the charging pile does not have a pre-set second authorization code, prompting the user to perform verification within a preset time, and obtaining the second authorization code after the verification is completed.

[0016] Preferably, the method further includes: obtaining a second authorization code after verification is completed.

[0017] Preferably, the vehicle identification information is the vehicle Bluetooth MAC address, and the verification credential is an authentication key; wherein, the authentication key is a key generated by the vehicle VIN code and the vehicle Bluetooth MAC address;

[0018] And / or,

[0019] The method further includes: verifying whether the vehicle VI N code and the vehicle Bluetooth MAC address are empty values.

[0020] Preferably, the step of binding the target vehicle based on the verification credential involves sending an authentication key to the target vehicle, enabling the target vehicle to decrypt the authentication key and compare it with a preset key to complete the binding between the charging pile and the vehicle.

[0021] Preferably, the method further includes: after binding the target vehicle, saving the vehicle VI N code and the vehicle Bluetooth MAC address.

[0022] Preferably, the target vehicle controls the opening and closing of the charging port cover based on the plugging / unplugging state by sending a corresponding command to the vehicle Bluetooth module based on the plugging / unplugging state. The vehicle Bluetooth module converts the command into a CAN signal and sends it 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.

[0023] Preferably, the method further includes: verifying whether the first authorization code is empty.

[0024] Secondly, this disclosure proposes an automatic control system for an electric vehicle charging port cover, comprising:

[0025] The mobile terminal binding module is used to respond to connection requests initiated by the mobile terminal, obtain authentication information sent by the mobile terminal, perform security verification, and bind the mobile terminal.

[0026] The receiving module is used to receive vehicle identification information and verification credentials sent by the mobile terminal.

[0027] The target vehicle binding module is used to search for target vehicles corresponding to the vehicle identification information within a preset range, and bind the target vehicles based on the verification credentials;

[0028] The charging port cover control module is used to obtain the plugging / unplugging status of the charging gun based on the user's plugging / unplugging actions, and send the plugging / 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 / unplugging status.

[0029] The beneficial effects of this invention are:

[0030] 1. The method of the present invention binds the target vehicle to the charging pile and monitors the insertion and removal status of the charging gun on the charging pile. Then, it controls the opening and closing of the charging port cover of the target vehicle by controlling the insertion and removal status of the charging gun. This solves the inaccuracy problem caused by premature opening or closing of the charging port cover in the prior art and improves the user experience.

[0031] 2. Perform security verification between the mobile terminal and the charging pile to ensure the security and legality of each connection, prevent connection errors, ensure correct identification of the target vehicle, and accurately control the opening and closing of the charging port cover. This can prevent problems such as the inability to control the opening and closing of the charging port cover due to connection errors or identification failures.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Before providing a further detailed description of the embodiments of the present invention, the nouns and terms involved in the embodiments of the present invention are explained, and the nouns and terms involved in the embodiments of the present invention are subject to the following interpretations:

[0041] Mobile App: An app developed by the OEM and pre-installed on various mobile phones. In this disclosure, it is mainly used for information exchange with charging piles and the OEM's TSP platform.

[0042] Automaker-developed vehicle-to-everything (V2X) platform: The V2X cloud platform developed by OEMs occupies a core position in the V2X industry chain. Its main function in this disclosure is to interact with mobile apps and provide relevant information required by vehicles and charging stations.

[0043] Vehicle Bluetooth module: A module installed inside the vehicle based on low-power Bluetooth communication. Externally, it can communicate and interact with charging piles and mobile apps via Bluetooth technology. Internally, it can communicate and interact with the vehicle's body domain controller via 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 instruction messages from the Bluetooth module and drive the charging port cover to execute instructions.

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

[0046] S1. In response to the connection request initiated by the mobile terminal, obtain the 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; the first authorization code is obtained by the mobile terminal from the vehicle manufacturer's vehicle-to-everything (V2X) platform. The first authorization code is a string of numbers generated in a fixed format, such as: EE1F1120A3ADF86C45B25059A8D1A923.

[0048] Furthermore, the authentication information sent by the mobile terminal is obtained, security verification is performed, and the mobile terminal is bound, including:

[0049] S11. Obtain the authentication request and first authorization code sent by the 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] In a preferred embodiment of this disclosure, the method further includes: if the charging pile does not have a pre-set second authorization code, the charging pile will prompt the user to perform verification within a preset time, and obtain the second authorization code after verification. For example, the verification process is as follows: if the charging pile does not have a pre-set second authorization code, the charging pile will prompt "Please swipe the charging card," and the user will use the charging card that is compatible with the charging pile for unique card swiping verification (the charging card and charging pile are one-to-one). If the user does not swipe the card at this time, the process will exit after a timeout (the timeout period can be manually set). If the user swipes the card, the charging pile sends a "User has swiped card" status message to the mobile terminal, and the mobile terminal will resend the second authorization code to the charging pile for comparison. Furthermore, the charging pile will write the received second authorization code into its internal storage space.

[0052] It should be further clarified that the mobile terminal can be either hardware or software. When the mobile terminal is hardware, it can be various electronic devices with a display screen that support communication with a backend server and the vehicle, such as smart wearable devices, mobile phones, tablets, in-vehicle terminals, laptops, and desktop computers. When the mobile terminal is software, it can be installed on the aforementioned electronic devices. The mobile terminal can be implemented as multiple software programs or software modules, or as a single software program or software module; this disclosure does not impose any limitations on this. Furthermore, various applications (APPs) can be installed on the mobile terminal, such as mini-program applications and charging station applications.

[0053] The mobile terminal initiates a connection request, including: the mobile terminal searches for and identifies a specific charging station using wireless communication technologies (such as Bluetooth, Wi-Fi, NFC, etc.). For example, when a user clicks the "My Charging Stations" icon in the car manufacturer's mobile app, the app's underlying system begins scanning for nearby Bluetooth devices and uses an internal whitelist to lock down the Bluetooth devices that need to be connected, displaying them in the app. The app then first checks if the Bluetooth device is one that has been previously connected locally. If not, it prompts the user to "Manually connect via Bluetooth," and the user clicks the Bluetooth connection icon in the app.

[0054] By performing security verification between the mobile terminal and the charging station, the security and legitimacy of each connection are ensured, and connection errors are prevented. It also ensures correct identification of the target vehicle and precise control of the opening and closing of the charging port cover, preventing problems caused by connection errors or identification failures that prevent control of the charging port cover opening and closing.

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

[0056] Among them, vehicle identification information is used to uniquely identify a specific vehicle. Verification credentials are used to confirm the vehicle's identity and permissions.

[0057] S3. Search for the target vehicle corresponding to the vehicle identification information within the preset range, and bind the target vehicle based on the verification certificate;

[0058] Specifically, the vehicle identification information is the vehicle's Bluetooth MAC address, and the verification credential is the authentication key. The authentication key is generated using the vehicle's VIN and Bluetooth MAC address. The vehicle's Bluetooth MAC address and VIN are obtained by the mobile terminal from the vehicle manufacturer's vehicle-to-everything (TSP) platform.

[0059] As a preferred embodiment of this disclosure, binding the target vehicle based on the verification credential includes: sending an authentication key to the target vehicle so that the target vehicle can decrypt the authentication key and compare and verify it with a preset key to complete the binding between the charging pile and the vehicle.

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

[0061] For example, the mobile app sends the vehicle's VIN code, vehicle's Bluetooth MAC address, and authentication key—required for Bluetooth connection between the charging station and the vehicle—to the charging station. When the vehicle approaches the charging station (within Bluetooth range), the charging station actively scans for nearby Bluetooth devices. Upon detecting the vehicle's Bluetooth MAC address, it sends the authentication key. The vehicle's Bluetooth module receives the authentication key (generated from the vehicle's VIN code and Bluetooth MAC address), decrypts it, and compares it with a pre-set key. If they don't match, the process terminates; otherwise, the binding between the charging station and the vehicle is complete. After binding, the charging station sends the binding completion information to the mobile app. The mobile app saves the vehicle's VIN code and Bluetooth MAC address so that the next time the phone connects to the charging station, it can automatically connect by matching the locally cached Bluetooth device identifier.

[0062] Reference Figure 3 As shown, S4: Obtain the plugging / unplugging status of the charging gun based on the user's plugging / unplugging action, and send the plugging / unplugging status to the target vehicle so that the target vehicle can control the opening and closing of the charging port cover based on the plugging / unplugging status.

[0063] Specifically, the target vehicle controls the opening and closing of the charging port cover based on the plugging / unplugging state by sending a corresponding command to the vehicle's Bluetooth module based on the plugging / unplugging state. The vehicle's Bluetooth module is used to convert the command into a CAN signal and send it to the body domain controller so that the body domain controller can control the opening and closing of the target vehicle's charging port cover.

[0064] For example, the automatic opening process when the charging station is unplugged is as follows: After the charging station and vehicle are paired, the user presses the handle button on the charging gun in the charging station to unplug the charging gun. At this time, the charging station detects that the charging gun has been unplugged and immediately sends a command message to the vehicle's Bluetooth module to open the charging port cover. After receiving the message, the vehicle's 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 automatically open, allowing the user to plug in the charging gun for charging. The automatic closing process when the charging station is unplugged is as follows: After the user finishes charging, they unplug the charging gun and put it back in the charging station. When the charging station detects that the charging gun has been returned to its original position, it sends a command to close the charging port cover to the vehicle's Bluetooth module. After receiving the message, the vehicle's 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 automatically close.

[0065] By binding the target vehicle to the charging station and monitoring the insertion and removal status of the charging gun on the charging station, the opening and closing of the charging port cover of the target vehicle can be controlled by the insertion and removal status of the charging gun. This solves the inaccuracy problem caused by premature opening or closing of the charging port cover in the existing technology and improves the user experience.

[0069] The target vehicle binding module is used to search for target vehicles corresponding to vehicle identification information within a preset range and bind the target vehicles based on verification credentials.

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