[0019] In order to enable those skilled in the art to better understand the solution of this specification, the technical solution in the implementation of this specification will be clearly and completely described below in conjunction with the drawings in the implementation of this specification. Obviously, the described implementation is only a part of the implementation of this specification, not all of the implementations. Based on the implementation in this specification, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0020] In the related art, the fuel tank cap serves as a sealing device for the fuel tank, and mainly plays the role of ensuring the sealing of the fuel tank and preventing fuel evaporation and leakage. The vehicle-mounted fuel tank cap, especially for vehicles with large fuel reserves such as light trucks and heavy trucks, may become the main target of criminals stealing fuel. Therefore, a locking structure of the fuel tank cap is necessary, and a key or knob is usually used to lock and unlock it. However, the convenience of the unlocking method in the related art 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 insufficient knowledge of some users and as the types of available fuel increase, they often add the wrong fuel or unqualified fuel, causing damage to the fuel engine.

[0022] This specification provides a vehicle fuel tank cap control device. Figure 1 , Figure 1 A schematic diagram of a vehicle-mounted fuel tank cover control device provided in an embodiment of the present specification. The vehicle-mounted fuel tank cover control device may include a main control module, a first NFC module, an energy storage capacitor module, a step-down conversion module, a drive module, and a locking structure for locking the fuel tank cover.

[0023] Among them, the first NFC module can collect the electric energy provided by the external second NFC module, so that the collected electric energy can be provided to the main control module, the driving module, the energy storage capacitor module, the buck conversion module and other modules in the vehicle-mounted fuel tank cover control device, and the first NFC module can realize the data transmission and reception between the main control module and the second NFC module, so that the passive vehicle-mounted fuel tank cover control device can realize the intelligent control of the fuel tank cover unlocking. Exemplarily, the first NFC module and the second NFC module refer to a near field communication (Near Field Communication, NFC) module or a near field communication device, which can perform contactless data exchange and communication within a short distance, such as within 10 cm. NFC modules can establish wireless connections through the principle of electromagnetic induction to achieve fast and convenient information transmission and interaction. Specifically, one NFC module can be used as a main module to send a high-frequency electromagnetic signal, and the other NFC module can be used as a passive module to generate current or electric energy through electromagnetic induction, thereby reading or responding to the signal sent by the main module.

[0024] The energy storage capacitor module can store the electric energy collected by the first NFC module. Specifically, in the process of the first NFC module collecting external electric energy, the energy storage capacitor module can store at least part of the electric energy collected by the first NFC module. The driving module can be used to unlock the locking structure. Exemplarily, the driving module can be an H-bridge driver, for example, a single-channel H-bridge driver. The buck conversion module can perform a buck operation on the electric energy provided by the first NFC module after the first NFC module supplies power to the modules in the vehicle-mounted fuel tank cover control device for a period of time to achieve stable power supply, so that the main control module can perform fuel tank cover unlocking control after achieving stable power supply.

[0025] For example, the main control module may use a HT66L2550A microcontroller, the driving module may use a HT7K1201 single-channel H-bridge driver chip, and the buck conversion module may use a HT7463C asynchronous buck converter.

[0026] The specific functions and effects achieved by the vehicle-mounted fuel tank cover control device can be explained in other embodiments of this specification, and will not be repeated here. Each module in the vehicle-mounted fuel tank cover control device can be implemented in whole or in part by software, hardware, or a combination thereof. Each module can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute the operations corresponding to each of the above modules.

[0027] This specification provides a method for controlling a vehicle fuel tank cap. Figure 2 , Figure 2 This is a flow chart of a vehicle fuel tank cap control method provided by this embodiment. This embodiment provides method operation steps as shown in the flow chart, but may include more or fewer operation steps based on conventional or non-creative labor. The order of steps listed in the embodiment is only one execution method among many step execution sequences, and does not represent the only execution sequence. When the actual system or server product is executed, it can be executed in sequence or in parallel according to the method shown in the embodiment (for example, in a parallel processor or multi-threaded processing environment). The vehicle fuel tank cap control method can be applied to the main control module in the vehicle fuel tank cap control device, specifically as Figure 2 As shown, the control method may include the following steps.

[0028] Step S210: Acquire a sample value of the electric energy in the energy storage capacitor module.

[0029] In some cases, the vehicle fuel tank cap can be opened based on the second NFC module, and the second NFC module outside the vehicle fuel tank cap can touch and charge the first NFC module in the vehicle fuel tank cap to unlock it. Specifically, the second NFC module can reversely power the first NFC module, and the first NFC module can collect the power provided by the second NFC module and power other modules in the vehicle fuel tank cap control device, for example, it can power the main control module, and can also store the collected power in the energy storage capacitor module.

[0030] Specifically, the main control module can monitor and detect the state of the electric energy in the energy storage capacitor module. For example, the main control module can perform ADC (Analog-to-Digital Converte) sampling on the electric energy of the energy storage capacitor module in real time to obtain a sampling value.

[0031] Step S220: when the sampled value meets the preset unlocking condition, the step-down conversion module is enabled to perform a step-down operation on the electric energy collected by the first NFC module, and after the step-down operation, the locking structure is unlocked.

[0032] The preset unlocking condition may be a preset sampling value, and satisfying the preset unlocking condition may mean being greater than or equal to the preset sampling value.

[0033] In some cases, when the sampling value does not meet the preset unlocking condition, or in other words, when the sampling value is less than the preset sampling value, the first NFC module can use the collected electric 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 condition. If so, the step-down conversion module is enabled to step down the electric energy collected by the first NFC module, thereby providing stable power supply for the main control module. After achieving stable power supply, the locking structure can be unlocked. In this way, the convenience of unlocking the vehicle's fuel tank cap can be improved.

[0035] In some embodiments, the first NFC module can realize data transmission and reception between the main control module and the second NFC module, and the vehicle-mounted fuel tank cover control device also includes a driving module.

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

[0037] Step S310: receiving the information to be verified sent by the second NFC module through the first NFC module.

[0038] In some cases, with the increase in available fuel types and the lack of awareness of some users, they often add wrong fuel or fill unqualified fuel, resulting in fuel engine damage. Therefore, the vehicle fuel tank cap can be opened only for authorized devices to reduce the occurrence of wrong fuel or filling unqualified fuel.

[0039] Step S320: determining 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 is unlocked by the driving module.

[0040] Specifically, the main control module can determine whether the second NFC module is an authorized device or an unauthorized device based on the information to be verified, and when the second NFC module is an authorized device, the locking structure is unlocked by the driving module. In this way, the vehicle's fuel tank cap can be opened only for authorized devices, thereby reducing the occurrence of wrong fueling or filling of unqualified fuel.

[0041] In some embodiments, the vehicle-mounted fuel tank cap control method may further include: when the second NFC module is an authorized device, determining whether the second NFC module is a single-authorization device; if the second NFC module is a single-authorization device, after unlocking the locking structure, reclaiming the authority of the second NFC module.

[0042] In some cases, the authorized device may be time-limited. For example, the authorized device may be a one-time authorized device or a long-term authorized device.

[0043] Specifically, the main control module can determine whether the second NFC module is a one-time authorization device. If the second NFC module is determined to be a one-time authorization device, the authority of the second NFC module can be reclaimed after the locking structure is unlocked, that is, the second NFC module no longer has the authority to open the vehicle's fuel tank cap. In this way, the security of the vehicle's fuel tank cap control can be improved while the flexibility of authority setting can be improved.

[0044] In some embodiments, the control method may further include: when the second NFC module is an unauthorized device, sending 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; and determining that the second NFC module is an authorized device in response to the authorization instruction.

[0045] In some cases, the control terminal may refer to a vehicle-mounted control terminal, and the control terminal may be connected to the vehicle-mounted fuel tank cap control device by wire or wirelessly.

[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; wherein the first authorization request is used to request the control terminal to issue an authorization instruction. After receiving the first authorization request sent by the main control module, the control terminal can determine the authorization instruction based on the first authorization request, and issue the authorization instruction to the main control module. After receiving the authorization instruction issued by the control terminal, the main control module can determine that the second NFC module is an authorized device in response to the authorization instruction, so that the subsequent main control module can unlock the locking structure. In this way, the flexibility of permission setting can be further improved while improving the security of vehicle-mounted fuel tank cover control.

[0047] In some embodiments, the authorization instruction may further include authorization time limit information. As an example, the authorization time limit information may refer to authorization unlocking times information. As another example, the authorization time limit information may refer to authorization period information.

[0048] In this embodiment, determining the second NFC module as an authorized device in response to the authorization instruction may include: determining the second NFC module as a single-time authorized device or a long-term authorized device in response to the authorization instruction. In this way, the flexibility of authority setting can be further improved while improving the security of vehicle fuel tank cover control.

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

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

[0051] In some cases, the scenarios for refueling a vehicle are complex and varied. For example, a vehicle needs to refuel at an unfamiliar refueling station or refuel by itself. At this time, the second NFC module is often not authorized and is an unauthorized device.

[0052] Specifically, the main control module can send a first authorization request carrying the filling station information to the control terminal when the second NFC module is an unauthorized device. After receiving the first authorization request, the control terminal can send a second authorization request carrying the filling station information to the control center based on the filling station information, and the second authorization request is used to request the control center to send the filling station matching information. After obtaining the filling station matching information, the control terminal determines the authorization instruction based on the filling station matching information, so that the main control module can determine whether to use the second NFC module as an authorized device, or determine whether to use the second NFC module as a single authorization device or a long-term authorization device based on the authorization instruction. In this way, the flexibility of authority setting can be further improved while improving the security of vehicle-mounted fuel tank cover control.

[0053] The embodiment of the present specification provides a vehicle-mounted fuel tank cover control method, which can be applied to a main control module in a vehicle-mounted fuel tank cover control device. The control method may include the following steps.

[0054] Step S401: Acquire a sample value of the electric energy in the energy storage capacitor module.

[0055] Step S402: when the sampled value meets the preset unlocking condition, the step-down conversion module is enabled to perform a step-down operation on the electric energy collected by the first NFC module.

[0056] Step S403: Receive the information to be verified 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 information to be verified. If so, go to step S404; otherwise, go to step S407.

[0057] Step S404: When the second NFC module is an authorized device, determine whether the second NFC module is a one-time authorized device, if so, go to step S405, otherwise go to step S406.

[0058] Step S405: unlocking the locking structure, and after unlocking, reclaiming the authority of 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] Exemplarily, the first authorization request carries the filling 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 filling station information, and the second authorization request is used to request the control center to send the filling station matching information so that the control terminal can determine the authorization instruction based on the filling station matching information.

[0062] Step S408: If an authorization instruction sent by the control terminal is received, the second NFC module is determined to be an authorized device in response to the authorization instruction.

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