[0015] In order to make the above objectives, characteristics and advantages of the present disclosure more obvious and easy to understand, the present disclosure will be further described in detail below with reference to the drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.

[0016] The vehicle charging port cover control method according to some embodiments of the present disclosure is executed in a zone controller in a vehicle, the vehicle further comprising a car Bluetooth module, a charging port cover and a body control module, the zone controller and the car Bluetooth module being in communication connection through a vehicle bus, and the body control module being in communication connection with the zone controller and the charging port cover through wires. In actual implementation, the body control module can be integrated in the zone controller to save vehicle space resources and improve the communication speed between the zone controller and the body control module.

[0017] In some embodiments, the charging port cover is an electric charging port cover, which has functions of touch / press sensing, electric opening, electric closing, position feedback, etc.

[0018] FIG. 1 is a flowchart of a vehicle charging port cover control method according to some embodiments of the present disclosure. Referring to FIG. 1, the method of the present disclosure can comprise steps S11 to S14:

[0019] In step S11, in a case where it is determined that the vehicle needs to access a first charging pile, it is detected whether a first radio frequency signal representing opening of the charging port cover is received, the first charging pile being a charging pile that has a binding relationship with the vehicle.

[0020] In some embodiments, the first charging pile is a private charging pile.

[0021] The first charging pile is provided with a radio frequency module, which can emit RF (Radio Frequency) signals or LF (Low Frequency) signals. In wireless communication, RF signals generally refer to electromagnetic waves with a frequency range of 3 kHz to 300 GHz. LF signals generally refer to electromagnetic waves with a frequency range of 30 kHz to 300 kHz.

[0022] The first radio frequency signal can be an RF signal or an LF signal.

[0023] When the vehicle drives to the vicinity of the first charging pile, if the user needs to connect the vehicle to the first charging pile for charging, the user will pull out the charging gun of the first charging pile. When the first charging pile detects that the charging gun is pulled out, a first radio frequency signal is sent to the outside through the radio frequency module, and the first radio frequency signal indicates that the charging port cover of the vehicle needs to be opened.

[0024] In step S12, if the first radio frequency signal is received, it is determined whether the signal characteristics of the first radio frequency signal are consistent with the signal characteristics of the standard radio frequency signal corresponding to the first charging pile.

[0025] If the area controller receives the first radio frequency signal, it will compare the signal characteristics of the first radio frequency signal with the signal characteristics of the standard radio frequency signal corresponding to the first charging pile stored in advance. The signal characteristics of the standard radio frequency signal can uniquely determine the first charging pile. If the signal characteristics of the first radio frequency signal are consistent with the signal characteristics of the standard radio frequency signal, it indicates that the first charging pile is a pre-bound charging pile (when bound, the cloud server will issue the signal characteristics of the standard radio frequency signal of the first charging pile to the area controller), at this time, the authentication is passed. If the signal characteristics of the first radio frequency signal are not consistent with the signal characteristics of the standard radio frequency signal, it indicates that the first charging pile is not a pre-bound charging pile, and at this time, the authentication is not passed.

[0026] In step S13, if the signal characteristics are consistent with the signal characteristics of the standard radio frequency signal, the first distance between the vehicle and the first charging pile is determined through the vehicle Bluetooth module.

[0027] In some embodiments, step S13 can include:

[0028] The first distance sent by the vehicle Bluetooth module is received, and the vehicle Bluetooth module is configured to determine the first distance according to the strength of the Bluetooth signal sent by the first charging pile when the Bluetooth connection with the first charging pile is established; or the strength of the Bluetooth signal sent by the vehicle Bluetooth module is received, and the first distance is determined according to the strength, and the vehicle Bluetooth module is configured to send the strength of the Bluetooth signal sent by the first charging pile to the area controller when the Bluetooth connection with the first charging pile is established.

[0029] In some embodiments, the vehicle has established a Bluetooth pairing with the first charging pile in advance. When the vehicle drives to the vicinity of the first charging pile, the vehicle Bluetooth module can detect the Bluetooth signal sent by the first charging pile. After Bluetooth connection authentication and AES256 key authentication, if the authentication is passed, the vehicle Bluetooth module establishes a Bluetooth connection with the Bluetooth module in the first charging pile. If the area controller detects that the vehicle Bluetooth module has established a Bluetooth connection with the first charging pile, it is determined that the vehicle needs to access the first charging pile. Then, the vehicle Bluetooth module determines the distance between the vehicle and the first charging pile according to the Bluetooth connection signal strength (the strength of the received Bluetooth signal) and transmits the distance to the area controller through the vehicle bus. The vehicle Bluetooth module can calculate the distance between the vehicle and the first charging pile every preset time interval, and then send it to the area controller. The preset time interval is generally set to be small to ensure that the area controller can obtain a more accurate first distance. The first distance is the latest distance received by the area controller.

[0030] In some embodiments, the vehicle Bluetooth module can also send the strength of the received Bluetooth signal sent by the first charging pile to the area controller to determine the first distance. The specific way to determine the first distance can be set according to actual needs.

[0031] In some embodiments, after the installation of the first charging pile is completed, the characteristic information (including the signal characteristics of the standard radio signal) of the first charging pile can be uploaded to the cloud server. When the user establishes a Bluetooth pairing between the vehicle and the first charging pile in advance, the cloud server automatically issues the characteristic information of the first charging pile to the area controller, and the area controller saves the characteristic information of the first charging pile.

[0032] In some embodiments, the first charging pile can be a private charging pile. The first charging pile can be bound to multiple different vehicles, and the same vehicle can also be bound to multiple different first charging piles. Binding means that a Bluetooth pairing is established and the area controller stores the characteristic information of the first charging pile.

[0033] In some embodiments, the strength of the received Bluetooth signal can be determined by RSSI (Received Signal Strength Indication). The Bluetooth connection authentication and AES256 key authentication can refer to existing technologies, and the present disclosure does not limit this.

[0034] In step S14, if the first distance is within the first preset distance range, the charging port cover is opened by the body control module.

[0035] The first preset distance range can be set according to experience, and the present disclosure does not make specific limitations on this.

[0036] In some embodiments, after detecting the radio frequency signal sent by the first charging pile, the regional controller first compares the signal characteristics of the radio frequency signal with the signal characteristics of the pre-stored standard radio frequency signal (corresponding to the first charging pile uniquely), and if they are consistent, it continues to detect whether the distance between the first charging pile and the vehicle is within the set range, and if it is within the set range, it opens the charging port cover of the vehicle. When there are many other vehicles to be charged in the vicinity of the vehicle, it can effectively avoid the situation of the charging port cover being opened by mistake, optimizing the charging experience of the user.

[0037] The vehicle can also include a keyless start module and / or a Bluetooth digital key module, the regional controller is in communication connection with the Bluetooth digital key module through the vehicle bus and in communication connection with the keyless start module through wires. In some embodiments, the keyless start module can be integrated inside the regional controller to save vehicle space resources and improve the communication speed between the keyless start module and the regional controller.

[0038] The method according to some embodiments of the present disclosure can also include:

[0039] In the case where it is determined that the vehicle needs to access the second charging pile, it is detected whether a pressing signal representing the opening of the charging port cover is received, the second charging pile being a charging pile that has not established a binding relationship with the vehicle;

[0040] If the pressing signal is received, the opening of the charging port cover is controlled through the keyless start module; or, the opening of the charging port cover is controlled through the Bluetooth digital key module.

[0041] In some embodiments, the second charging pile can be a public charging pile.

[0042] When the user charges in a public place, the charging port cover can be pressed to indicate the need to open the charging port cover, and after the charging port cover detects the pressing signal, the pressing signal is sent to the regional controller.

[0043] After the regional controller receives the pressing signal, it can control the opening of the charging port cover in any one of the following two ways:

[0044] First: the opening of the charging port cover is controlled through the keyless start module.

[0045] Second: the opening of the charging port cover is controlled through the Bluetooth digital key module.

[0046] The first opening method can include:

[0047] Through the keyless start module, it is detected whether a second radio frequency signal sent by a remote control key carried by the user is received;

[0048] If the second radio frequency signal is received, the second distance between the vehicle and the remote key is determined according to the strength of the received second radio frequency signal by the keyless entry module.

[0049] If the second distance is within the second preset distance range, the charging port cover is opened by the vehicle body control module.

[0050] The second radio frequency signal can be an RF signal or an LF signal.

[0051] In some embodiments, after the area controller receives the pressing signal, the following steps are performed by the keyless entry module: searching for all remote keys in the vicinity that are sending radio frequency signals, authenticating the identity of each remote key, obtaining a legal key that passes the authentication, determining the second distance between the vehicle and the legal key according to the strength of the second radio frequency signal sent by the legal key, and then determining whether the second distance is within the second preset distance range. If so, the charging port cover is opened by the vehicle body control module.

[0052] The identity authentication of each remote key can be implemented according to existing technology. The second preset range can be set according to experience.

[0053] In some embodiments, the second opening method can include:

[0054] Detecting whether an instruction indicating opening of the charging port cover is received from the Bluetooth digital key module, the instruction being obtained by the Bluetooth digital key module through the following steps: establishing a Bluetooth connection with the digital key module on the user terminal, determining a third distance between the Bluetooth digital key module and the user terminal according to the strength of the Bluetooth signal received from the digital key module, and generating the instruction if the third distance is within a third preset distance range.

[0055] If the instruction is received, the charging port cover is opened by the vehicle body control module.

[0056] In some embodiments, the user terminal is installed with a digital key module (i.e., a terminal digital key).

[0057] In some embodiments, after the area controller receives the pressing signal, the pressing signal is sent to the Bluetooth digital key module, and the Bluetooth digital key module performs the following steps: searching for all devices in the vicinity that are sending Bluetooth signals, sequentially authenticating the identity of each device until a digital key module that passes the authentication is found, then establishing a Bluetooth connection with the digital key module, determining the strength of the Bluetooth signal connection by RSSI, determining a third distance between the Bluetooth digital key module and the digital key module according to the strength, generating an instruction indicating opening of the charging port cover if the third distance is within a third preset distance range, and sending the instruction to the area controller. After the area controller receives the instruction, the charging port cover is opened by the vehicle body control module.

[0058] Through the first opening mode or the second opening mode, the identity of the user can be actively identified and the charging port cover can be automatically opened without the user actively operating the charging port cover by using the remote key, thereby providing convenience for charging of the vehicle.

[0059] FIG. 2 is a schematic diagram of an interaction principle of a vehicle and a charging pile according to an embodiment of the present disclosure. In FIG. 2, the private charging pile is internally provided with a 4G / 5G module, a Bluetooth module, and a radio frequency module. The 4G / 5G module is used to interact with a cloud server. The Bluetooth module can perform Bluetooth communication with a vehicle machine Bluetooth module. The radio frequency module can send RF signals or LF signals to the outside when the charging gun is pulled out.

[0060] The vehicle includes a vehicle machine Bluetooth module, a zone controller, a Bluetooth digital key module, and a charging port cover. The zone controller includes a keyless opening module and a vehicle body control module.

[0061] The vehicle machine Bluetooth module can perform Bluetooth communication with the private charging pile, authenticate the private charging pile (Bluetooth connection authentication and AES256 key authentication), and determine the distance between the vehicle and the private charging pile through Bluetooth RSSI.

[0062] The remote key can perform wireless communication with the keyless opening module in the zone controller through RF / LF. The keyless opening module can perform identity authentication and location positioning on the remote key.

[0063] The terminal digital key, i.e., a digital key module on a user terminal, can perform Bluetooth communication with the Bluetooth digital key module. The Bluetooth digital key module can perform identity authentication and location positioning on the terminal digital key.

[0064] The opening method of the charging port cover according to some embodiments of the present disclosure will be described in detail below in combination with FIG. 2. It should be noted that the charging pile used here is a private charging pile X, and the steps are as follows:

[0065] Step 1: After the private charging pile X is installed, the individualized radio frequency information (feature information corresponding to the private charging pile X only) is uploaded to the cloud server through the 4G / 5G module.

[0066] Step 2: The user operates the vehicle end APP (APP on the mobile phone) to establish Bluetooth pairing between the private charging pile X and the vehicle. During the Bluetooth pairing process, the cloud server downloads the individualized radio frequency information to the zone controller through the RVDC (Remote Vehicle Diagnostic Cloud, automobile remote diagnostic cloud platform), and the zone controller stores the information.

[0067] Step 3: When the infotainment Bluetooth module detects the Bluetooth signal of the private charging pile X nearby, the Bluetooth connection authentication and AES256 key authentication of the private charging pile X are performed, and after the authentication is successful, the Bluetooth connection between the infotainment Bluetooth module and the private charging pile X is established. The distance between the vehicle and the private charging pile X is identified through the RSSI signal strength, and the distance is transmitted to the area controller through the vehicle bus. The infotainment Bluetooth module can detect the distance every preset time interval and transmit the distance to the area controller. The preset time interval can be set to be relatively short, so that the area controller can obtain more accurate distance information.

[0068] Step 4: When the private charging pile X detects that the charging gun is pulled out, the radio frequency module transmits a radio frequency signal representing the opening of the charging port cover. The area controller receives the radio frequency signal and determines whether the signal characteristics of the radio frequency signal are consistent with the signal characteristics of the standard radio frequency signal in the personalized radio frequency information corresponding to the private charging pile X. If they are consistent, go to Step 5.

[0069] Step 5: The area controller determines whether the latest distance between the vehicle and the private charging pile X is within the pre-set effective range. If it is, the charging port cover is automatically opened by the vehicle body control module.

[0070] If the vehicle does not use the private charging pile X, but uses the public charging pile Y for charging, the opening process of the charging port cover includes:

[0071] Step 1: The user presses the switch of the charging port cover, and the charging port cover sends the detected pressing signal to the area controller.

[0072] Step 2: The area controller controls the opening of the charging port cover in any one of the following two ways:

[0073] The first way: The area controller detects whether there is a remote key nearby through the keyless entry module. If there is, and the identity authentication is passed, it is further determined whether the distance between the area controller and the remote key is within the effective range (set according to experience). If it is, the charging port cover is automatically opened by the vehicle body control module.

[0074] The second way: The area controller sends the pressing signal to the Bluetooth digital key module. The Bluetooth digital key module detects whether there is a terminal digital key nearby. If there is, and the identity authentication is passed, it is further determined whether the distance between the Bluetooth digital key module and the terminal digital key is within the effective range (set according to experience). If it is, an instruction representing the opening of the charging port cover is generated and sent to the area controller. The area controller automatically opens the charging port cover through the vehicle body control module.

[0075] In the present disclosure, the vehicle and the private charging pile can be bound in advance, and the vehicle can perform identity authentication and positioning on the private charging pile before charging, so as to truly realize the zero-contact and non-sensing opening and closing of the charging port cover when the vehicle owner charges at the private charging pile, and to avoid the mis-opening of the charging port cover. In the public charging pile scenario, through the keyless opening module or the Bluetooth digital key module of the vehicle, the identity of the user can be actively identified and the charging port cover can be automatically opened without the user actively operating the charging port cover by using the remote key, so as to simplify the opening operation and provide convenience for the charging of the vehicle.

[0076] It should be noted that, for the sake of simple description, the above description of the method steps is expressed as a series of action combinations, but those skilled in the art should know that the present disclosure is not limited by the order of the described actions, because according to the present disclosure, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should know that the embodiments described in the present disclosure are all preferred embodiments, and the actions involved are not necessarily necessary for the present disclosure.

[0077] According to the vehicle charging port cover control method of some embodiments of the present disclosure, after the area controller detects the radio frequency signal sent by the first charging pile, it first compares the signal characteristics of the radio frequency signal with the signal characteristics of the standard radio frequency signal (corresponding to the first charging pile) stored in advance. If they are consistent, the distance between the first charging pile and the vehicle is further detected to see whether it is within the set range. If it is within the set range, the charging port cover of the vehicle is opened. This can effectively avoid the mis-opening of the charging port cover and optimize the charging experience of the user.
