[0009] In some implementations, the authorization instruction further includes authorization validity information; determining the second NFC module as an authorized device in response to the authorization instruction includes: determining the second NFC module as a single-authorization device or a long-term authorization device in response to the authorization instruction.

[0010] In some implementations, the first authorization request carries information about the refueling station to which the second NFC module belongs. The control terminal can send a second authorization request to the control center based on the refueling station information.

[0019] To enable those skilled in the art to better understand the solutions described in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of them. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

[0020] In related technologies, the fuel tank cap, as a sealing device for the fuel tank, mainly plays the role of ensuring the fuel tank's airtightness and preventing fuel evaporation and leakage. For vehicle fuel tank caps, especially for vehicles with large fuel reserves such as light trucks and heavy trucks, they may become the main target for fuel theft. Therefore, a locking structure for the fuel tank cap is necessary. Usually, a key or knob is used to lock and unlock it. However, the convenience of the unlocking method in related technologies needs to be improved.

[0021] In some related technologies, the unlocking authority of the fuel tank cap locking structure is completely open to the user. However, due to a lack of understanding and the increasing variety of available fuels, some users often add the wrong fuel or substandard fuel, which can damage the fuel engine.

[0022] This specification provides an embodiment of a vehicle fuel tank cap control device. Please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of an on-board fuel tank cap control device provided in an embodiment of this specification. The on-board fuel tank cap control device may include a main control module, a first NFC module, an energy storage capacitor module, a step-down converter module, a drive module, and a locking structure for locking the fuel tank cap.

[0023] The first NFC module can collect power from an external second NFC module, enabling it to supply power to other modules in the vehicle fuel tank cap control device, such as the main control module, drive module, energy storage capacitor module, and step-down converter module. The first NFC module also enables data transmission and reception between the main control module and the second NFC module, thus allowing the passive vehicle fuel tank cap control device to achieve intelligent control of the fuel tank cap unlocking. For example, the first and second NFC modules refer to Near Field Communication (NFC) modules or devices, capable of contactless data exchange and communication within a short distance, such as 10 centimeters. NFC modules can establish a wireless connection through electromagnetic induction, enabling fast and convenient information transmission and interaction. Specifically, one NFC module can act as the main module, emitting a high-frequency electromagnetic signal, while the other NFC module acts as a passive module, generating current or electrical energy through electromagnetic induction to read or respond to the signal emitted by the main module.

[0024] The energy storage capacitor module can store the electrical energy collected by the first NFC module. Specifically, during the process of the first NFC module collecting external electrical energy, the energy storage capacitor module can store at least a portion of the electrical energy collected by the first NFC module. The drive module can be used to unlock the locking structure. Exemplarily, the drive module can be an H-bridge driver, such as a single-channel H-bridge driver. The buck converter module can step down the electrical energy provided by the first NFC module after the first NFC module has been supplying power to the module in the vehicle fuel tank cap control device for a period of time, in order to achieve stable power supply, so that the main control module can perform fuel tank cap unlocking control after stable power supply is achieved.

[0025] For example, the main control module can be an HT66L2550A microcontroller. The driver module can be an HT7K1201 single-channel H-bridge driver chip. The buck converter module can be an HT7463C asynchronous buck converter.

[0026] The specific functions and effects of the vehicle fuel tank cap control device can be explained by referring to other embodiments in this manual, and will not be repeated here. Each module in the vehicle fuel tank cap control device can be implemented entirely or partially through software, hardware, or a combination thereof. Each module can be embedded in or independent of the processor in a computer device in hardware form, or it can be stored in the memory of a computer device in software form, so that the processor can call and execute the operations corresponding to each module.

[0027] This specification provides a method for controlling a vehicle fuel tank cap. Please refer to [link / reference]. Figure 2 , Figure 2 This is a flowchart illustrating a vehicle fuel tank cap control method provided in this embodiment. This embodiment provides the method operation steps shown in the flowchart, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiment is merely one possible execution order among many, and does not represent the only possible execution order. In actual system or server product execution, the method can be executed sequentially as shown in the embodiment or in parallel (e.g., in a parallel processor or multi-threaded processing environment). This vehicle fuel tank cap control method can be applied to the main control module in a vehicle fuel tank cap control device, specifically as follows... Figure 2 As shown, the control method may include the following steps.

[0028] Step S210: Obtain the sampled value of electrical energy in the energy storage capacitor module.

[0029] In some cases, the vehicle's fuel tank cap can be opened using a second NFC module. The second NFC module on the outside of the fuel tank cap can touch and charge the first NFC module inside the fuel tank cap to unlock it. Specifically, the second NFC module can provide reverse power to the first NFC module. The first NFC module can collect the power provided by the second NFC module and use it to power other modules in the vehicle's fuel tank cap control device. For example, it can power the main control module or store the collected power in an energy storage capacitor module.

[0030] Specifically, the main control module can monitor and detect the electrical energy status in the energy storage capacitor module. For example, it can perform ADC (Analog-to-Digital Converter) sampling on the electrical energy of the energy storage capacitor module in real time to obtain the sampled value.

[0031] Step S220: When the sampled value meets the preset unlocking conditions, enable the step-down conversion module to perform a step-down operation on the electrical energy collected by the first NFC module, and unlock the locking structure after the step-down operation.

[0032] The preset unlocking condition can be a preset sample value, and meeting the preset unlocking condition can mean being greater than or equal to the preset sample value.

[0033] In some cases, when the sampled value does not meet the preset unlocking conditions, or when the sampled value is less than the preset sampled value, the first NFC module can use the collected electrical energy to power the main control module to enable it to operate.

[0034] Specifically, the main control module can determine whether the sampled value meets the preset unlocking conditions. If it does, it enables the step-down conversion module to step down the power collected by the first NFC module, thereby providing a stable power supply to the main control module. After achieving a stable power supply, the locking structure can be unlocked, thus improving the ease of unlocking the vehicle fuel tank cap.

[0035] In some implementations, the first NFC module can realize data transmission and reception between the main control module and the second NFC module, and the vehicle fuel tank cap control device also includes a drive module.

[0036] In this embodiment, the vehicle fuel tank cap control method may further include the following steps before unlocking the locking structure.

[0037] Step S310: Receive the verification information sent by the second NFC module through the first NFC module.

[0038] In some cases, due to the increasing variety of available fuels and a lack of awareness among some users, incorrect fuel or substandard fuel is often added, leading to damage to the fuel engine. Therefore, the vehicle's fuel tank cap can be opened only for authorized devices to reduce the occurrence of incorrect fuel addition or substandard fuel.

[0039] Step S320: Determine whether the second NFC module is an authorized device based on the information to be verified, so that if the second NFC module is an authorized device, the locking structure can be unlocked through the driver module.

[0040] Specifically, the main control module can determine whether the second NFC module is an authorized or unauthorized device based on the information to be verified. If the second NFC module is an authorized device, the driving module can unlock the locking structure. In this way, the vehicle fuel tank cap can be opened only for authorized devices, thereby reducing the possibility of adding the wrong fuel or adding unqualified fuel.

[0041] In some implementations, the vehicle fuel tank cap control method may further include: if the second NFC module is an authorized device, determining whether the second NFC module is a single-use authorized device; if the second NFC module is a single-use authorized device, then after unlocking the locking structure, revoking the permissions of the second NFC module.

[0042] In some cases, licensed devices may have time limits; for example, licensed devices may be single-use or long-term licensed devices.

[0043] Specifically, the main control module can determine whether the second NFC module is a single-use authorized device. If the second NFC module is determined to be a single-use authorized device, the permissions of the second NFC module can be revoked after the locking structure is unlocked. That is, the second NFC module will no longer have the permission to open the vehicle fuel tank cap. In this way, the security of the vehicle fuel tank cap control can be improved while the flexibility of permission settings can be increased.

[0044] In some implementations, the control method may further include: sending a first authorization request to a control terminal when the second NFC module is an unauthorized device; wherein the first authorization request is used to request the control terminal to issue an authorization instruction; and determining that the second NFC module is an authorized device in response to the authorization instruction.

[0045] In some cases, the control terminal can refer to the vehicle-mounted control terminal, which can be connected to the vehicle-mounted fuel tank cap control device via wired or wireless connection.

[0046] Specifically, if the second NFC module is determined to be an unauthorized device, the main control module can send a first authorization request to the control terminal; this first authorization request is used to request the control terminal to issue an authorization command. Upon receiving the first authorization request from the main control module, the control terminal can determine the authorization command based on the request and issue the authorization command to the main control module. After receiving the authorization command from the control terminal, the main control module can determine that the second NFC module is an authorized device, thus enabling the main control module to unlock the locking structure. This improves both the security of the vehicle fuel tank cap control and the flexibility of access control settings.

[0047] In some implementations, the authorization instruction may also include authorization validity information. As one example, authorization validity information may refer to the number of authorization unlock attempts. As another example, authorization validity information may refer to authorization time period information.

[0048] In this embodiment, determining that the second NFC module is an authorized device in response to an authorization command may include: determining whether the second NFC module is a single-authorization device or a long-term authorization device in response to the authorization command. This improves the security of the vehicle fuel tank cap control while further enhancing the flexibility of permission settings.

[0049] In some implementations, the first authorization request may carry the refueling station information to which the second NFC module belongs. The control terminal can send a second authorization request to the control center based on the refueling station information. The second authorization request is used to request the control center to issue refueling station matching information so that the control terminal can determine the authorization instruction based on the refueling station matching information.

[0050] The refueling station information may include refueling station area information and / or refueling station type information.

[0051] In some cases, the scenarios for refueling a vehicle are complex and varied. For example, a vehicle may need to refuel at an unfamiliar refueling station or refuel itself. In such cases, the second NFC module is often unauthorized and is an unauthorized device.

[0052] Specifically, if the second NFC module is an unauthorized device, the main control module can send a first authorization request carrying refueling station information to the control terminal. Upon receiving the first authorization request, the control terminal can send a second authorization request carrying refueling station information to the control center. This second authorization request requests the control center to issue refueling station matching information. After obtaining the refueling station matching information, the control terminal determines the authorization command based on this information. This allows the main control module to determine whether to use the second NFC module as an authorized device, or whether to use it as a single-use or long-term authorized device. This improves the security of the vehicle fuel tank cap control while further enhancing the flexibility of permission settings.

[0053] This specification provides a method for controlling a vehicle fuel tank cap, which can be applied to the main control module of a vehicle fuel tank cap control device. The method may include the following steps.

[0054] Step S401: Obtain the sampled value of electrical energy in the energy storage capacitor module.

[0055] Step S402: If the sampled value meets the preset unlocking conditions, enable the step-down converter to perform a step-down operation on the electrical energy collected by the first NFC module.

[0056] Step S403: Receive the verification information sent by the second NFC module through the first NFC module, and determine whether the second NFC module is an authorized device based on the verification information. If yes, proceed to step S404; otherwise, proceed to step S407.

[0057] Step S404: If the second NFC module is an authorized device, determine whether the second NFC module is a single-authorization device. If yes, proceed to step S405; otherwise, proceed to step S406.

[0058] Step S405: Unlock the locking structure, and after unlocking, revoke access to the second NFC module.

[0059] Step S406: Unlock the locking structure.

[0060] Step S407: Send a first authorization request to the control terminal; wherein the first authorization request is used to request the control terminal to issue an authorization instruction.

[0061] For example, the first authorization request carries the refueling station information to which the second NFC module belongs; the control terminal can send a second authorization request to the control center based on the refueling station information. The second authorization request is used to request the control center to issue refueling station matching information so that the control terminal can determine the authorization instruction based on the refueling station matching information.

[0062] Step S408: If an authorization command is received from the control terminal, determine that the second NFC module is an authorized device in response to the authorization command.

[0063] Specifically, the authorization instruction may include authorization validity information, and the main control module may respond to the authorization instruction to determine whether the second NFC module is a single-authorization device or a long-term authorization device.
