Description

Technical Field

[0001] This disclosure relates to the field of vehicle control technology, and in particular to a control method for opening a vehicle fuel filler cap, a vehicle infotainment system, a vehicle, and equipment. Background Technology

[0002] Accidental opening of the fuel filler cap has been a key pain point for both the industry and users in daily vehicle use and refueling scenarios. Current fuel filler cap opening methods mostly rely on manual unlocking from inside the vehicle, mechanical key operation, or single sensor triggering, lacking a scenario recognition and operation verification mechanism to determine whether the refueling request is genuine, leading to frequent accidental activation risks. Whether the vehicle encounters road bumps or roadside obstacles while driving, or is bumped by foreign objects or accidentally touched by people while parked, the fuel filler cap unlocking mechanism may be accidentally triggered, causing the cap, which should be locked, to open abnormally.

[0003] Currently, the industry's solutions to the problem of accidental activation of the fuel filler cap have significant shortcomings: some models only reduce the probability of accidental activation through dual operations of unlocking from inside the vehicle and pressing from the outside, but accidental activation may still occur while the vehicle is in motion due to malfunction of the operating mechanism or accidental contact; other models use simple distance sensing or Bluetooth unlocking technology, but the sensing range is difficult to control and is easily affected by environmental interference, which either leads to the inconvenience problem of not being able to open when it should, or the safety hazard of accidentally locking when it should not be opened.

[0004] In summary, the existing technology has the technical problem of accidental opening of the vehicle's fuel filler cap. Summary of the Invention

[0005] In view of the above problems, this disclosure provides a control method, vehicle system, vehicle, and equipment for overcoming or at least partially solving the problem of accidental opening of the vehicle fuel filler cap. The technical solution is as follows: A method for controlling the opening of a vehicle fuel filler cap, the method comprising: When the vehicle is in a preset position, monitor whether there is any tapping information indicating that the preset position of the vehicle is being tapped. In response to detecting tapping information at the preset location, the validity of the tapping information is checked. In response to the valid tapping information, the filler cap is opened.

[0006] By combining the vehicle's position in a preset location with tapping information monitoring and validity detection, the core pain points of existing fuel filler cap opening methods are addressed from two dimensions: scenario limitation and operation verification. On one hand, the limitation of the preset location (such as a specific area around the gas station) ensures that the fuel filler cap only has the ability to open in actual refueling scenarios, avoiding the risk of accidental opening due to accidental touches or bumps in non-refueling scenarios such as vehicle driving or daily parking. This effectively protects the sealing of the vehicle's fuel system, preventing fuel evaporation and leakage, and the entry of debris, thus ensuring driving safety and fuel system stability. On the other hand, using tapping information as the opening trigger condition eliminates the cumbersome process of relying on manual unlocking by the driver (including high-pressure fuel tank depressurization). Refueling personnel do not need to wait for the driver to complete a series of actions such as parking, shifting gears, and unlocking; they can directly trigger the opening by tapping, significantly shortening the waiting time before refueling. This not only improves the operational convenience and user experience for refueling personnel but also reduces the time vehicles spend in the gas station, effectively alleviating congestion. At the same time, the innovative human-vehicle interaction method also brings users a more intelligent and efficient driving experience.

[0007] Optionally, the step of detecting tapping information at the preset location and performing validity detection on the tapping information includes: In response to detecting tapping information at the preset position, the tapping information is identified and tapping parameters are determined; In response to the tapping parameters matching the preset tapping parameters, the tapping information is determined to be valid.

[0008] This approach improves the accuracy and reliability of fuel filler cap opening control by identifying and determining the tapping parameters from the monitored tapping information, and then matching them with preset tapping parameters to determine validity. Existing technologies lack an effective mechanism for identifying trigger signals, making them susceptible to unintentional touches, road bumps, foreign object collisions, and other irrelevant interference signals, leading to accidental opening or failure to open the fuel filler cap. This solution, by extracting and matching tapping parameters, can distinguish between the refueling personnel's active operations and various invalid interference signals, ensuring that only tapping actions that meet preset standards trigger the opening command. This avoids problems such as fuel leakage, safety hazards, and fuel system damage caused by accidental opening. Furthermore, this parameter-matching-based validity detection method requires no additional complex operating steps; refueling personnel only need to tap according to the conventional preset method to complete the trigger. While ensuring control accuracy, it does not affect operational convenience, balancing safety and efficiency while reducing the system's false trigger rate, thus increasing user trust in the vehicle's intelligent control functions and user satisfaction.

[0009] Optionally, the preset tapping parameters may include at least a preset tapping rhythm, a preset number of taps, and a preset tapping force threshold. The step of determining the validity of the tapping information in response to a match between the tapping parameters and the preset tapping parameters includes: In response to the tapping parameters satisfying the preset tapping rhythm, the preset number of taps, and the preset tapping force threshold, the tapping information is determined to be valid. If the tapping parameters do not meet one of the preset tapping rhythm, the preset number of taps, and the preset tapping force threshold, the tapping information is determined to be invalid.

[0010] In this way, by clearly defining the preset tapping parameters, including the preset tapping rhythm, preset tapping frequency, and preset tapping force threshold, and requiring all three to be simultaneously satisfied for the tapping information to be considered valid, a multi-dimensional and three-dimensional validity verification system is constructed, further enhancing the safety and accuracy of the refueling cap opening control. Single-dimensional tapping parameters (such as only detecting force or frequency) are easily circumvented by unintentional operations, such as random tapping by children while playing or a single strong impact during an accidental collision, which may falsely trigger the opening command. However, this solution, through the triple limitation of rhythm, frequency, and force, forms mutually restrictive and complementary verification conditions, which can filter out various invalid taps that are not intended for refueling: it avoids misjudgments caused by insufficient or excessive force, and also eliminates random operations with chaotic rhythms or incorrect frequency, ensuring that only tapping actions performed by refueling personnel according to the preset specifications can pass the verification. This multi-dimensional verification mechanism not only significantly reduces the risk of accidental activation, but also adapts to the usage needs of different gas station scenarios. Even in noisy environments or with slight interference, it can still accurately identify valid tapping signals, ensuring stable system operation without increasing the operational difficulty for gas station staff. It balances safety and rigor with ease of use, making the smart activation function more practical and reliable.

[0011] Optionally, the method further includes: In response to the invalid tapping information, count the number of invalid taps. In response to the invalid number exceeding a preset threshold, the filler cap is locked for a preset time period.

[0012] By counting invalid taps, the fuel filler cap is locked for a preset time period when the number of invalid taps exceeds a preset threshold, thus establishing an effective safety protection mechanism and further improving the safety and stability of the vehicle's fuel system. In real-world scenarios, there may be malicious attempts by others to open the fuel filler cap, unintentional repeated taps by children, or continuous interference from foreign objects. Without corresponding protective measures, not only may the fuel filler cap be opened accidentally, but system resources may also be occupied by invalid operations, affecting the response efficiency of normal refueling needs. This solution, through invalid tap counting and a temporary locking mechanism, can effectively curb malicious operations and frequent accidental taps: for malicious attempts, the temporary locking can prevent them from continuously trying, protecting the vehicle's fuel from being stolen or damaged; for unintentional frequent accidental taps, the locking function can prevent the system from repeatedly performing invalid detection and response, reducing system wear and tear and improving operational stability. Meanwhile, the preset time period locking design takes into account both safety and flexibility of use. The locking time can be reasonably set according to actual needs, so that it will not affect normal refueling due to long-term locking, and can form effective protection during risky periods, ensuring that the refueling cap opening function operates within a safe and controllable range, providing users with a more reassuring driving environment.

[0013] Optionally, before controlling the opening of the filler cap, the method further includes: Obtain the status information of the vehicle, which is used to characterize the operating status of the vehicle; In response to the status information meeting the safe opening conditions, the refueling cap is controlled to open.

[0014] This approach, by adding vehicle status information acquisition and safety opening condition judgment steps before controlling the opening of the fuel filler cap, constructs a safety protection barrier from the perspective of the vehicle's own operating status, effectively avoiding the safety risks caused by opening the fuel filler cap when the vehicle is in an unsafe state. Opening the fuel filler cap under different operating conditions can cause different safety hazards. For example, opening it while the vehicle is not turned off or parked may cause fuel atomization and leakage due to engine operation, potentially leading to a fire; opening it before the high-pressure fuel tank has been fully depressurized may cause fuel vapor to spray out instantly, posing a risk of burns or explosion. This solution ensures that the fuel filler cap opening action matches the vehicle's safety status by acquiring vehicle status information and only executing the opening command when the safety opening conditions are met. This design not only specifically addresses the safety hazards caused by neglecting vehicle status in traditional opening methods but also demonstrates adaptability to different vehicle operating scenarios. Whether the vehicle is in a normal parking state or a special state such as a high-pressure fuel tank, status detection ensures the safety of the opening process, protecting the safety of passengers, refueling personnel, and the surrounding environment. It also allows users to use the intelligent opening function with greater peace of mind, improving the safety of the function and user acceptance.

[0015] Optionally, the method further includes: Obtain the vehicle type of the vehicle; The safety activation conditions are determined based on the vehicle type.

[0016] By determining the safe opening conditions based on vehicle type, the universality and adaptability of the control method are improved, enabling it to meet the personalized safety needs of different vehicle types (such as conventional gasoline vehicles, high-pressure fuel tank vehicles, and hybrid vehicles). Different vehicle types have different fuel system structures and safety requirements: the core of safe opening for conventional gasoline vehicles lies in whether the vehicle is turned off or parked; while high-pressure fuel tank vehicles require additional conditions such as complete depressurization; hybrid vehicles may also involve special requirements such as power mode switching. Using uniform safe opening conditions would either fail to meet the safety needs of special vehicle types or impose unnecessary operational restrictions on conventional vehicles. This solution achieves a vehicle-specific safety control approach by first obtaining the vehicle type and then setting targeted safe opening conditions: for high-pressure fuel tank vehicles, complete depressurization is automatically included in the safety conditions; for conventional gasoline vehicles, the focus is on the core conditions of engine shutdown and parking, avoiding redundant detection. This design not only eliminates the need to develop separate control logic for different vehicle models, reducing vehicle R&D and production costs, but also ensures that the opening of the fuel filler cap for each vehicle model strictly adheres to its own exclusive safety standards. This not only guarantees the safety of use for various vehicle models, but also avoids safety loopholes or cumbersome operations caused by common conditions. It allows the intelligent opening function to be widely adapted to different vehicle types, enhancing the market application value and practicality of the technical solution.

[0017] Optionally, the method further includes: In response to the vehicle being at the preset position, the environmental information of the vehicle is acquired; In response to the presence of a target object and / or refueling equipment in the environmental information, the occurrence time of the target object and / or the refueling equipment is determined; In response to the occurrence time of the knocking information falling within a preset time window, the fuel filler cap of the vehicle is controlled to open.

[0018] In this way, by acquiring environmental information when the vehicle is in a preset location, and determining whether the appearance time of the target object (such as refueling personnel) and / or refueling equipment and the occurrence time of the effective tapping information are within a preset time window, the prediction of the refueling scenario and the synchronous matching of the opening action are achieved, further improving the rationality and safety of the control method. When the vehicle is in a preset location such as a gas station, there may be non-immediate refueling scenarios such as temporary parking or waiting for refueling. If the refueling cap is opened solely based on the tapping information and the vehicle's position, invalid opening may occur when there is no refueling demand, leading to problems such as fuel evaporation and the entry of debris. However, this solution, through environmental information detection, confirms the presence of refueling-related target objects or equipment in the vicinity, and that their appearance time is close to the effective tapping time, thus determining that the current situation is a real refueling scenario, ensuring that the opening action is triggered only when there is an actual refueling demand. This design not only further filters out the risk of accidental opening in non-refueling scenarios, but also makes the refueling process more seamless: once the refueling personnel arrive at the vehicle and prepare the refueling equipment, they can open the fuel filler cap by tapping it, without any additional waiting or operation, thus improving refueling efficiency. At the same time, it avoids fuel leakage and safety hazards caused by opening the fuel filler cap too early, and also prevents the refueling experience from being affected by delayed opening. It achieves organic linkage between scene recognition, personnel / equipment detection and tapping trigger, making the fuel filler cap opening control more intelligent and more in line with actual use scenarios, taking into account safety, convenience and rationality.

[0019] A control device for opening a vehicle fuel filler cap, the device comprising: The monitoring module is used to monitor whether there is any tapping information indicating that the vehicle is tapped at a preset position when the vehicle is in a preset position. The detection module is used to detect the validity of the tapping information in response to the detection of tapping information on the preset position; The control module is used to control the opening of the filler cap in response to the valid tapping information.

[0020] Optionally, the detection module is also used for: In response to detecting tapping information at the preset position, the tapping information is identified and tapping parameters are determined; In response to the tapping parameters matching the preset tapping parameters, the tapping information is determined to be valid.

[0021] Optionally, the preset tapping parameters may include at least a preset tapping rhythm, a preset number of taps, and a preset tapping force threshold. The detection module is also used for: In response to the tapping parameters satisfying the preset tapping rhythm, the preset number of taps, and the preset tapping force threshold, the tapping information is determined to be valid.

[0022] If the tapping parameters do not meet one of the preset tapping rhythm, the preset number of taps, and the preset tapping force threshold, the tapping information is determined to be invalid.

[0023] Optionally, the control device for opening the vehicle's fuel filler cap may also include a statistics module; The statistics module is used to count the number of invalid taps in response to invalid tap information. In response to the invalid number exceeding a preset threshold, the filler cap is locked for a preset time period.

[0024] Optionally, before controlling the opening of the fuel filler cap, the control device for opening the vehicle fuel filler cap further includes a first acquisition module; The first acquisition module is used to acquire the status information of the vehicle, the status information being used to characterize the operating status of the vehicle; In response to the status information meeting the safe opening conditions, the refueling cap is controlled to open.

[0025] Optionally, the control device for opening the vehicle's fuel filler cap also includes a second acquisition module: The second acquisition module is used to acquire the vehicle type of the vehicle; The safety activation conditions are determined based on the vehicle type.

[0026] Optionally, the control device for opening the vehicle's fuel filler cap also includes a third acquisition module: The third acquisition module is used to acquire the environmental information of the vehicle in response to the vehicle being at the preset position; In response to the presence of a target object and / or refueling equipment in the environmental information, the occurrence time of the target object and / or the refueling equipment is determined; In response to the occurrence time of the knocking information falling within a preset time window, the fuel filler cap of the vehicle is controlled to open.

[0027] This embodiment also provides a vehicle infotainment system, including: a memory and a processor, wherein the memory stores executable program code, and the processor is used to call and execute the executable program code to execute the control method for opening the vehicle fuel filler cap as described above.

[0028] This embodiment also provides a vehicle, including a control method for opening the fuel filler cap as described in any of the above-described embodiments.

[0029] This embodiment also provides an electronic device, including a memory, a processor, and a computer program stored in the memory. When the processor executes the computer program, it implements any of the optional vehicle fuel filler cap opening control methods described above.

[0030] Using the above technical solution, the present disclosure provides a control method for opening a vehicle fuel filler cap. First, when the vehicle is in a preset position, it monitors whether there is tapping information indicating that the preset position of the vehicle is being tapped. Second, in response to the detection of tapping information indicating that the preset position is being tapped, the validity of the tapping information is detected. Finally, in response to the validity of the tapping information, the fuel filler cap is controlled to open. In this way, through a coherent process of preset location limitation, tap information monitoring, and validity detection, intelligent control of the fuel filler cap opening is achieved. On the one hand, the preset location limitation ensures that the system only activates and responds in real refueling scenarios, avoiding the risk of accidental opening due to accidental touch or bumps in non-refueling scenarios such as vehicle driving or daily parking. This effectively protects the sealing of the vehicle's fuel system, preventing fuel evaporation and leakage, and the intrusion of foreign matter. At the same time, it is compatible with special models such as high-pressure fuel tanks, eliminating the need for the driver to perform additional pressure relief operations, thus ensuring the safety of the fuel system from the source of the scenario. On the other hand, using tapping as the trigger method, combined with validity detection, eliminates the cumbersome process of relying on the driver to manually unlock the cap. This allows refueling personnel to directly trigger the opening without waiting for the vehicle to come to a complete stop, significantly shortening the waiting time before refueling and alleviating gas station congestion. It can also distinguish between valid operations and irrelevant interference signals, avoiding accidental triggering and significantly improving operational convenience. In addition, this new tapping-based human-vehicle interaction method simplifies the operation process for gas station staff and reduces the operational burden on drivers, achieving a triple improvement in safety, convenience, and user experience, making the refueling process more efficient and worry-free.

[0033] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0034] In existing vehicle designs, the opening and closing of the fuel filler cap primarily relies on the driver's active operation. Common methods include issuing an unlock command via a physical button, cable, or touchscreen, which then triggers the fuel filler cap locking mechanism via the vehicle's control module. While this in-vehicle-triggered mode can generally meet routine refueling needs, its limitations become increasingly apparent in the high-frequency usage scenario of gas stations: firstly, the efficiency of the refueling process is limited by the driver's reaction time and operating speed; secondly, the fuel filler cap itself lacks the ability to effectively detect unintentional external touches.

[0035] Of particular concern is the risk of accidental unlocking. In everyday use, the fuel filler cap area may experience mechanical vibrations or pressure signals due to unintentional contact such as the impact of a high-pressure water gun during a car wash, accidental physical contact by pedestrians, curious tapping by children, or even collisions by small animals. If the system design relies solely on a single vibration sensor or pressure switch, the fuel filler cap is highly susceptible to accidental unlocking outside of refueling scenarios, potentially causing fuel system contamination, mechanical damage to the cap, and posing a safety hazard. Current solutions attempting external unlocking, such as automatic unlocking via Bluetooth sensing of the fuel nozzle's proximity, while offering some convenience, fail to effectively distinguish between the approach of the fuel nozzle and the proximity of other metal objects or malicious tool probes, thus amplifying the risk of accidental unlocking and lacking sufficient safety robustness.

[0036] To address the technical problem of accidental opening of the vehicle fuel filler cap in existing technologies, this disclosure provides a control method for opening the vehicle fuel filler cap, such as... Figure 1 As shown, Figure 1 This is a schematic flowchart illustrating a control method for opening a vehicle fuel filler cap according to an embodiment of this disclosure. The method includes: S11. When the vehicle is in a preset position, monitor whether there is any tapping information indicating that the preset position of the vehicle is being tapped.

[0037] Specifically, the vehicle being in a preset location is a scenario activation condition, which can be achieved based on positioning technology and electronic fence technology. By comparing the vehicle positioning system with a pre-stored gas station map database, it can be determined whether the vehicle has entered the relevant valid refueling area, thus avoiding the system from operating ineffectively in non-refueling scenarios such as while driving or in ordinary parking lots.

[0038] Monitoring tapping information is the core of operation perception. Based on elastic wave detection technology, a dedicated sensing module captures tapping motions in the fuel filler cap area, converting mechanical tapping into a recognizable signal. This replaces the traditional manual unlocking trigger method from inside the vehicle, enabling direct operation by refueling personnel. The two work together to form an operation monitoring logic that only activates when certain conditions are met, reducing system redundancy and improving the targeted nature of operation triggering.

[0039] In one specific embodiment, the definition and implementation of the preset location can rely on an onboard positioning system. Its core components include a GPS / BeiDou locator and an electronic fence unit. The preset range is clearly defined as 50-100 meters around the gas station. The positioning system continuously monitors the vehicle's location during driving and compares it in real time with a pre-stored database of gas stations and navigation maps. Once the vehicle is determined to have entered the electronic fence area, the elastic wave sensing module is immediately activated, switching the system from a dormant state to a standby monitoring state. The preset location of the vehicle specifically refers to the area where the fuel filler cap is located. The corresponding impact detection is achieved through the elastic wave sensing module, which includes an acoustic emission sensor array and an elastic wave metasurface structure. Based on the acoustic emission principle, it can capture the elastic wave signal generated by mechanical impacts on the fuel filler cap area, distinguishing it from interference signals such as collisions and bumps from other parts of the vehicle. The detection range and sensitivity of the sensing module are specifically calibrated to respond only to impacts on the fuel filler cap area and convert the captured elastic wave signal into an electrical signal, providing raw data for subsequent validity testing.

[0040] For example, when a vehicle enters the 80-meter electronic fence of a gas station, the positioning system confirms the validity of the scenario, and the elastic wave sensor module is immediately activated to monitor in real time whether the fuel filler cap has been knocked. However, when the vehicle is driving on a highway or parked in a residential area, which are not electronic fence areas, even if the fuel filler cap is hit, the system will not activate the monitoring because the preset position conditions are not met, thus avoiding false triggering from the source.

[0041] In this embodiment, a strong association is established between specific scenarios and specific operations to avoid the risk of accidental triggering in non-refueling scenarios from the source, while providing basic triggering conditions for subsequent control. This step filters effective use scenarios by limiting their location and captures user-initiated operations by tapping. Essentially, it achieves preliminary verification of scenario validity and operational intent, ensuring that the system only initiates subsequent responses in real refueling demand scenarios. This not only protects the safety of the vehicle's fuel system (avoiding accidental activation in non-refueling scenarios) but also lays the foundation for the convenience goal of eliminating the need for driver operation.

[0042] S12. In response to detecting tapping information at a preset position, perform validity detection on the tapping information.

[0043] Specifically, the system receives the tapping electrical signals captured by the S11 and extracts, analyzes, and compares the signal features using signal processing technology and pattern recognition algorithms. Its core technology principle is feature matching verification. This involves pre-setting a set of effective tapping standards (such as specific rhythm, number of taps, and force) that conform to the operating habits of refueling scenarios. The signal processing module then performs noise reduction and feature extraction (such as tapping frequency, interval time, and signal strength) on the original tapping signal, and compares it with the pre-set standards to determine whether the tapping information is valid. This step filters out unintentional interference signals (such as wind-blown foreign object impacts or random tapping by children) while ensuring standardized operation, making the tapping activation function both convenient and controllable, avoiding safety risks caused by overly low operational thresholds.

[0044] In one specific embodiment, validity detection can be performed by a signal processing module, which includes a microprocessor and a prior knowledge base. The core of the determination relies on a deep learning-based pattern recognition algorithm. First, the microprocessor preprocesses the electrical signal transmitted by the elastic wave sensing module, filtering out interference factors such as road noise and vehicle vibration, and extracting the core feature parameters of the striking signal, including a specific rhythmic striking pattern, as well as extended striking frequency and striking force thresholds. Second, the prior knowledge base stores pre-trained valid striking pattern data (such as a "two short, one long" rhythm, three consecutive strikes, and a force between 0.5 and 2N, etc.). The algorithm compares the extracted real-time feature parameters with the preset parameters in the knowledge base one by one. Simultaneously, during the determination process, a second verification is performed to confirm whether the vehicle is still within the preset electronic fence area (to prevent the vehicle from responding to striking after leaving the area). Only when the striking feature parameters match the preset standards and the vehicle has not left the electronic fence is the striking information deemed valid.

[0045] For example, when a refueling attendant operates according to a preset rhythm of two quick taps followed by one long tap, the signal processing module will quickly identify the rhythm characteristics, the number of taps must meet the standard, and the force must meet the threshold, thus determining it as a valid signal. However, a single arrhythmic tap caused by a roadside pebble hitting the ground or a child's random tapping while playing will be determined as an invalid signal because the rhythm is not right, the number of taps is insufficient, or the force is insufficient. The system will not initiate the subsequent activation process, effectively avoiding the risk of accidental triggering.

[0046] In this embodiment, by performing multi-dimensional verification on the captured tapping information, the system distinguishes between the active and compliant operation of the refueling personnel and invalid signals such as unintentional touch, collision with foreign objects, and environmental interference. This ensures that the subsequent opening process is only initiated when there is a valid operation with a genuine refueling intention. This guarantees the accuracy and safety of system control from the signal level, avoids the accidental opening of the refueling cap due to invalid signals, and further strengthens the determination of specific operation intentions, making up for the safety shortcomings of single-location limitation.

[0047] S13. In response to a valid tapping signal, control the opening of the filler cap.

[0048] Specifically, after the signal processing module outputs a valid tapping command, the body control module receives the command and performs a final safety status verification. Once it confirms that the vehicle meets the safety conditions for opening, it sends an unlocking signal to the electromagnetic lock and other actuators, automatically opening the fuel filler cap. This step is not a simple direct execution of a command, but includes a secondary safety check of the entire vehicle's status, ensuring that the opening action is only performed when the vehicle is in a safe condition (such as when the high-pressure fuel tank has been depressurized or the vehicle is parked), achieving a balance between convenience and safety.

[0049] In one specific embodiment, firstly, after receiving a valid opening command from the signal processing module, the vehicle control module checks the vehicle status, including but not limited to: whether the vehicle is parked, whether the engine is off, and whether the high-pressure fuel tank has been depressurized, ensuring that the opening process will not cause safety risks such as fuel leakage or fire. Secondly, when the vehicle status meets the safety conditions, the vehicle control module sends an unlocking signal to the electromagnetic lock of the fuel filler cap. After receiving the signal, the electromagnetic lock releases the locking structure, realizing the automatic opening of the fuel filler cap. The entire process does not require any operation from the driver, and the refueling personnel can start refueling directly. Finally, after refueling is completed, when the refueling personnel manually close the fuel filler cap, the electromagnetic lock will automatically reset and lock. At the same time, when the vehicle leaves the electronic fence area of ​​the gas station, the system will automatically disable the knock-to-open function, restoring the fuel filler cap to the normal locked state, forming a complete closed loop of use.

[0050] For example, when a high-pressure fuel tank vehicle enters the electronic fence of a gas station, the refueling personnel tap the fuel filler cap at a preset rhythm. After verification by S11 and S12, the vehicle control module first confirms that the high-pressure fuel tank has been depressurized and the vehicle has been parked and turned off. Then, it drives the electromagnetic lock to unlock, and the fuel filler cap automatically pops open. This not only avoids the cumbersome process of the driver getting out of the car to unlock and wait for the pressure to be released, but also ensures the safety of opening the high-pressure fuel tank through status verification, greatly improving refueling efficiency and user experience.

[0051] In this embodiment, the scenario verification and operation verification of the first two steps are transformed into actual functional output, realizing closed-loop control that automatically opens after effective judgment. Ultimately, the goal of convenience is achieved, which eliminates the need for the driver to manually unlock and allows refueling personnel to quickly start refueling. At the same time, through safety verification during the execution process, the safety and reliability of the refueling cap opening are ensured, solving the core pain points of long waiting time and cumbersome operation in traditional opening methods.

[0052] In the above scheme, firstly, when the vehicle is in a preset position, it monitors whether there is any tapping information indicating that the preset position of the vehicle is being tapped; secondly, in response to the detection of tapping information indicating that the preset position is being tapped, the validity of the tapping information is checked; finally, in response to the valid tapping information, the fuel filler cap is controlled to open. In this way, through a coherent process of preset location limitation, tap information monitoring, and validity detection, intelligent control of the fuel filler cap opening is achieved. On the one hand, the preset location limitation ensures that the system only activates and responds in real refueling scenarios, avoiding the risk of accidental opening due to accidental touch or bumps in non-refueling scenarios such as vehicle driving or daily parking. This effectively protects the sealing of the vehicle's fuel system, preventing fuel evaporation and leakage, and the intrusion of foreign matter. At the same time, it is compatible with special models such as high-pressure fuel tanks, eliminating the need for the driver to perform additional pressure relief operations, thus ensuring the safety of the fuel system from the source of the scenario. On the other hand, using tapping as the trigger method, combined with validity detection, eliminates the cumbersome process of relying on the driver to manually unlock the cap. This allows refueling personnel to directly trigger the opening without waiting for the vehicle to come to a complete stop, significantly shortening the waiting time before refueling and alleviating gas station congestion. It can also distinguish between valid operations and irrelevant interference signals, avoiding accidental triggering and significantly improving operational convenience. In addition, this new tapping-based human-vehicle interaction method simplifies the operation process for gas station staff and reduces the operational burden on drivers, achieving a triple improvement in safety, convenience, and user experience, making the refueling process more efficient and worry-free.

[0053] In some embodiments, such as Figure 2 As shown, in response to detecting tapping information at a preset location, the validity of the tapping information is checked, including: S121. In response to detecting tapping information at a preset position, identify the tapping information and determine the tapping parameters.

[0054] Specifically, based on the principle of acoustic emission and a deep learning pattern recognition algorithm, the electrical signal transmitted by the elastic wave sensing module is first preprocessed by noise reduction and filtering to remove irrelevant interference signals such as road vibration, environmental noise, and collisions with other parts of the vehicle body. Then, core features that characterize the essence of the striking action are extracted from the clean signal to form standardized striking parameters. This step not only solves the problem of the original signal being cluttered and chaotic, but also makes the striking action comparable through quantification features, providing a unified judgment dimension for parameter matching of S122 and ensuring the scientific nature and consistency of subsequent validity detection.

[0055] In one specific embodiment, when the elastic wave sensing module detects a tapping action on the fuel filler cap (preset position), it converts the elastic wave signal generated by the mechanical tapping into an analog electrical signal and transmits it to the signal processing module in real time. The microprocessor first performs digital conversion and preprocessing on the analog electrical signal, filtering out interference signals such as human voices, vehicle noise, and equipment operating sounds in the gas station environment through a filtering algorithm. At the same time, it removes weak signals caused by slight bumps in the vehicle body or slight contact with foreign objects, retaining only the core signal related to the active tapping to ensure the purity of the signal. Subsequently, the microprocessor extracts three core features from the preprocessed pure signal and quantifies them into specific parameters: first, the tapping rhythm parameter, i.e., the time interval between two adjacent taps and the overall temporal pattern of the tapping action, which can be calculated through the temporal distribution characteristics of the signal; second, the number of taps parameter, i.e., the number of signal pulses that meet the tapping intensity threshold per unit time, which is obtained through a counting algorithm; and third, the tapping force threshold parameter, i.e., the intensity of the elastic wave signal generated by the tapping (corresponding to the magnitude of the force applied during the tapping), which is calculated through the amplitude characteristics of the signal. The extracted tapping rhythm, number of taps, force, and other parameters are converted into standardized data that conforms to the prior knowledge base data format and temporarily stored in the cache of the signal processing module, waiting to be compared with the preset tapping parameters.

[0056] For example, when a refueling worker performs a tapping action on the fuel filler cap with "three consecutive taps, each with a 0.5-second interval, and a force of 1.2N", the elastic wave sensor module converts the action into an electrical signal. After processing by S121, it finally outputs standardized tapping parameters of "rhythm: 0.5-second interval, number of taps: 3, force: 1.2N", providing clear and quantitative data for the subsequent matching judgment of S122.

[0057] In this embodiment, the essence is to convert physical tapping actions into digital feature parameters. By removing invalid interference and extracting core features, the subsequent validity determination has a clear quantitative basis, avoiding misjudgment or omission due to signal ambiguity, and ultimately ensuring the accuracy and reliability of the tap-to-activate function.

[0058] S122. In response to the tapping parameters matching the preset tapping parameters, the tapping information is determined to be valid.

[0059] Specifically, the preset tapping parameters can include at least a preset tapping rhythm, a preset number of taps, and a preset tapping force threshold. These parameters are compared with pre-stored compliant parameters to output a valid or invalid result. If the tapping parameters meet the preset tapping rhythm, preset number of taps, and preset tapping force threshold, the tapping information is determined to be valid. If the tapping parameters do not meet any of these three thresholds, the tapping information is determined to be invalid.

[0060] In one specific embodiment, a priori knowledge base pre-stores preset tapping parameters (including rhythm, number of times, and force thresholds) that have been trained on numerous scenarios and conform to the actual operating habits of gas stations. The algorithm compares the real-time extracted tapping parameters with the preset parameters dimension by dimension to determine the degree of fit between the two. At the same time, the on-board positioning system is also linked during the determination process to conduct a secondary verification to confirm whether the vehicle is still within the electronic fence area of ​​the gas station (to prevent the vehicle from responding to tapping after leaving the area), forming a dual determination of parameter matching and scenario matching, further improving the reliability of the determination result.

[0061] Specifically, when the tapping information is invalid, the number of invalid taps is counted; when the number of invalid taps exceeds a preset threshold, the fuel filler cap is locked for a preset time period.

[0062] In one specific embodiment, the signal processing module counts the number of invalid taps in real time and establishes a short-term invalid operation counter. When the counter value exceeds a preset threshold, the signal processing module sends a temporary lock command to the vehicle control module. Upon receiving the command, the vehicle control module drives the electromagnetic lock of the fuel filler cap into a locked state and sets the lock duration. During the lock period, even if tapping information is detected, the system will directly block the validity detection process and not perform the unlocking operation until the lock period ends and normal response is automatically restored. This mechanism does not affect the effective operation in normal refueling scenarios, and can specifically prevent the risk of abnormal operation, thus balancing convenience and safety.

[0063] In this embodiment, a multi-dimensional parameter full-matching rule is used to distinguish between the refueling personnel's proactive compliant operations and invalid operations such as unintentional touching, malicious probing, and environmental interference, thereby preventing the accidental opening of the refueling cap from the root.

[0064] In the above scheme, the design of S121 identifying the tapping information and determining the tapping parameters, and S122 determining the validity of the tapping information through parameter matching, ensures that only the tapping action performed by the refueling personnel according to the preset standard can trigger the opening command, and eliminates the need for the driver to perform additional unlocking or depressurization operations. This convenient interactive design of tap-to-open significantly shortens the waiting time for refueling personnel, simplifies the operation process, alleviates gas station congestion, and enhances the practicality and user experience of intelligent refueling while strengthening the safety of the vehicle's fuel system.

[0065] In some embodiments, such as Figure 3 As shown, before controlling the opening of the fuel filler cap, the control method for opening the vehicle's fuel filler cap also includes: S14. Obtain the vehicle's status information, which is used to characterize the vehicle's operating status.

[0066] In one specific embodiment, relying on the vehicle status detection capability of the body control module, key data reflecting the vehicle's operating status are collected in real time through the vehicle's internal sensor network and bus system. This data covers the operating parameters of multiple core modules such as the power system, braking system, and fuel system. These scattered status data are then integrated into standardized information and transmitted to the body control module for subsequent judgment.

[0067] For example, the status information can include at least: powertrain status, braking and parking status, and fuel system-specific status. The core data for the powertrain status includes engine operating status (start / stop) and power mode (fuel mode / hybrid mode) to prevent fire risks caused by fuel atomization leakage during engine operation. This is a basic safety data collection item for all vehicle models. The braking and parking status data includes whether the parking brake (handbrake / electronic handbrake) is active and the gear position (whether it is in P / Park) to prevent accidents such as collisions with refueling personnel or damage to refueling equipment due to vehicle roll when the fuel filler cap is opened before the vehicle is stably parked. For high-pressure fuel tank models, the fuel tank depressurization status (whether depressurization is complete) is additionally collected. This is a core safety data collection item for high-pressure fuel tank models, as there is pressure inside the high-pressure fuel tank. If the fuel filler cap is opened without complete depressurization, fuel vapor will spray out instantly, potentially causing burns and posing a flammable and explosive risk. For ordinary fuel vehicles, the data includes the pressure balance status inside and outside the fuel tank to ensure no fuel splashing when opening the filler cap.

[0068] In this embodiment, by comprehensively collecting vehicle operating status data, a quantitative basis is provided for subsequent safe opening determination, and a safety protection barrier is constructed from the perspective of vehicle operation itself.

[0069] S15. In response to the status information meeting the safe opening conditions, control the opening of the refueling cap.

[0070] In one specific implementation, the vehicle control module first receives a valid tap and scene compliance opening command transmitted by the signal processing module, then calls the vehicle status information collected by S14 and compares it with the pre-stored safe opening conditions dimension by dimension; if all status dimensions meet the conditions, an unlocking drive command is generated to control the electromagnetic lock to perform the unlocking action; if any status dimension does not meet the conditions, the opening command is refused to be generated and the fuel filler cap remains locked.

[0071] In this embodiment, a closed-loop control system prioritizing safety and enabling compliant opening is achieved by matching status information with safe opening conditions. Its core logic is to execute the operation if the conditions are met and prohibit it if the conditions are not met. This ensures that all opening requests under unsafe conditions are directly rejected, while guaranteeing a rapid response when opening actions meet safe conditions, balancing the convenience of tap-to-open with the safety of the fuel system. This step addresses the potential risk of drivers overlooking vehicle status when manually unlocking in traditional methods. The system automatically determines the vehicle's status, replacing manual judgment and avoiding safety risks caused by human negligence. It also connects with the scenario and operation determinations mentioned earlier.

[0072] In the above scheme, the design of S14 obtaining vehicle status information and S15 responding to the status meeting safety conditions to control the opening of the fuel filler cap, with the system automatically verifying instead of manual judgment, without the need for additional operation by the driver, ensures that the refueling personnel can quickly start the refueling process after making a valid tap, reducing waiting time and alleviating gas station congestion, and makes the opening method without driver intervention more reliable through status compliance verification, thus achieving a deep integration of operational convenience and fuel system safety.

[0073] In some embodiments, such as Figure 4 As shown, the control method for opening the vehicle's fuel filler cap also includes: S16. Obtain the vehicle type.

[0074] Specifically, the fuel system design and safety risk points of different vehicle types (such as ordinary gasoline vehicles, high-pressure fuel tank vehicles, hybrid vehicles, etc.) are fundamentally different. Only by first clarifying the vehicle type can we formulate targeted safety opening rules to avoid safety redundancy (unnecessary operational restrictions imposed on ordinary vehicles) or safety deficiencies (special vehicles not covering exclusive risk points) caused by general safety conditions. Ultimately, while ensuring ultimate safety, we can also take into account the ease of use of various vehicle types, making the intelligent opening function adaptable to a wider range of vehicle scenarios.

[0075] In one specific embodiment, relying on the vehicle's built-in identification system and bus transmission network, key information that can characterize the vehicle type is extracted from the vehicle's core control unit. The information is then parsed using preset classification rules to ultimately determine the vehicle's type (such as a regular fuel vehicle, a high-pressure fuel tank fuel vehicle, a plug-in hybrid vehicle, etc.), and the type information is transmitted to the body control module to provide clear input for the formulation of the safe opening conditions of S17.

[0076] For example, conventional gasoline vehicles use atmospheric pressure fuel tanks and do not require high-pressure storage. Safety risks are concentrated in basic scenarios such as when the vehicle is not turned off or parked. High-pressure fuel tank vehicles use high-pressure fuel tank designs. In addition to the basic scenarios, the core safety risks include the unique risk of fuel vapor leakage due to failure to release pressure. Hybrid vehicles have both gasoline and electric power modes. The fuel system may be atmospheric pressure or high-pressure fuel tanks. There is an additional safety risk of the power mode not being switched to gasoline mode / shutdown mode. The safety of both the fuel system and the power system must be taken into account.

[0077] In this embodiment, identifying the specific vehicle type provides a core basis for subsequently setting differentiated safety activation conditions, addressing the differences in safety requirements among vehicles with different power types and fuel system structures. Essentially, it breaks away from a one-size-fits-all approach to safety standards, achieving on-demand, adaptive safety control.

[0078] S17. Determine the safe opening conditions based on the vehicle type.

[0079] In one specific embodiment, the vehicle control module has a built-in safety rule library covering various vehicle models. After receiving the vehicle type information transmitted by S16, it retrieves the basic safety conditions and exclusive safety conditions of the corresponding vehicle model from the rule library through a mapping algorithm, and then combines the two types of conditions into complete safety activation conditions, providing a clear judgment benchmark for the status information comparison of S15.

[0080] In this embodiment, based on the vehicle type identified by S16, a differentiated safety activation system is constructed, tailored to each vehicle type. This ensures that safety conditions cover the unique risk points of various vehicle models without creating redundant restrictions, achieving a dynamic balance between safety and convenience. Its core logic is type matching and risk targeting. For different vehicle types with varying fuel system structures and safety risks, corresponding judgment criteria are retrieved from a pre-stored safety rule base. This ensures that unnecessary safety checks are simplified for ordinary vehicles, while special vehicles receive enhanced risk control, resolving the problem of poor adaptability of traditional uniform safety conditions.

[0081] In the above scheme, the design of S16 obtaining the vehicle type and S17 determining the safe opening conditions based on the vehicle type breaks away from the one-size-fits-all unified safety standard by identifying the vehicle type. Relying on the prior knowledge base linkage between the body control module and the signal processing module, exclusive safe opening rules are customized for vehicles with different fuel system structures. This personalized adaptation design not only eliminates the need to develop control logic separately for different models, reducing technical adaptation costs, but also ensures that the safe opening conditions for each type of vehicle target its core risk points. While eliminating the need for drivers to manually unlock and depressurize, it maximizes the safety of the vehicle's fuel system and further enhances the practicality and adaptability of the tap-to-open human-vehicle interaction method, making the intelligent refueling experience efficient, worry-free, safe, and reliable.

[0082] In some embodiments, such as Figure 5 As shown, the control method for opening the vehicle's fuel filler cap also includes: S18. In response to the vehicle being in a preset position, obtain the vehicle's environmental information.

[0083] In one specific implementation, relying on the environmental perception hardware (such as cameras, millimeter-wave radar, ultrasonic sensors, etc.) on the vehicle, after the vehicle positioning system confirms that the vehicle has entered the electronic fence of the gas station, it automatically starts environmental data collection, captures target objects (such as refueling personnel), equipment (such as fuel nozzles, fuel dispensers) and environmental background information around the vehicle (focusing on the side of the fuel filler cap), and removes irrelevant interference (such as passing pedestrians, non-refueling equipment) through data preprocessing, extracts environmental feature information that is strongly related to the refueling scenario, and transmits it to the signal processing module and the vehicle control module.

[0084] In this embodiment, by collecting information about the vehicle's surrounding environment, the current scenario is further confirmed to be a real refueling scenario. This achieves dual scenario control through scenario access and environmental verification, preventing the refueling cap from being accidentally opened due to effective tapping (such as accidental operation by others or children playing) when the vehicle is temporarily stopped within the electronic fence of the gas station (such as waiting in line for refueling or briefly using the road) without actual refueling needs. At the same time, it ensures that the opening action is only performed when there are refueling-related entities / equipment in the vicinity, making the intelligent opening function more in line with the actual refueling process and taking into account both safety and scenario adaptability.

[0085] S19. In response to the presence of a target object and / or refueling equipment in the environmental information, determine the time of occurrence of the target object and / or refueling equipment.

[0086] In one specific embodiment, the signal processing module first performs matching and judgment on the standardized environmental information collected in S18, comparing it with the pre-stored target object feature library (such as the appearance and clothing characteristics of refueling personnel) and refueling equipment feature library (such as the structural characteristics of refueling machines and refueling nozzles) in the prior knowledge base to confirm whether there are real and valid target objects and / or refueling equipment in the environment; if it is determined that there are, the system time when the target object / equipment first enters the effective monitoring range is extracted, a timestamp is generated, and it is stored as the occurrence time and transmitted to the vehicle control module to provide a clear benchmark for subsequent comparison with the effective tapping time.

[0087] In this embodiment, by confirming the existence of refueling-related entities / equipment and recording their appearance time, a temporal correlation between the existence of the environment and the effective tapping is established. This further filters out invalid scenarios where there is an environment but no operation, or where there is operation but no environment, ensuring that the opening action of the refueling cap is a response to the genuine refueling intention. Only when there are indeed refueling personnel or equipment in the vicinity, and their appearance is temporally correlated with the tapping operation, is the prerequisite for opening possible. This avoids accidental opening caused by the presence of irrelevant personnel / equipment in the environment or a time discrepancy between the tapping and the appearance of the refueling entity.

[0088] S20. In response to the occurrence time and the occurrence time of the valid tapping information being within a preset time window, control the opening of the vehicle's fuel filler cap.

[0089] In one specific embodiment, the signal processing module transmits valid tapping information and its occurrence time, the appearance time of the target object / refueling device, and the vehicle status information it collects. First, it calculates the time difference between the valid tapping occurrence time and the appearance time, and then compares it with a preset time window threshold. If the time difference is within the threshold range and the vehicle status meets the safe opening conditions (such as engine off, parked, or high-pressure fuel tank depressurization completed), the body control module generates an unlocking command, drives the electromagnetic lock to perform the unlocking action, and controls the fuel filler cap to open. If the time difference exceeds the threshold or the vehicle status does not meet the requirements, the opening is refused, and the lock is maintained.

[0090] In this embodiment, by matching the time window of the occurrence time with the effective tapping time, it is ensured that the refueling cap opening action is only performed when the refueling-related main body / equipment is in place and the refueling personnel initiate the tapping operation immediately. Essentially, this addresses safety hazards caused by environmental factors unrelated to the operation, avoiding accidental opening due to situations such as the presence of refueling personnel who do not intend to refuel the vehicle, or effective tapping being a previous, unfinished operation. Simultaneously, matching the opening action with the refueling personnel's operational rhythm ensures both safety and accuracy without compromising refueling convenience.

[0091] In the above solution, by collecting information about the vehicle's surrounding environment in S18 and determining the presence of the target object and / or refueling equipment in S19, the fuel filler cap is prevented from being accidentally opened due to effective tapping when the vehicle is temporarily queuing or stopping at a gas station without actual refueling needs. This effectively protects the vehicle's fuel system seal and prevents fuel evaporation and leakage, as well as the intrusion of foreign objects, further enhancing fuel system safety. At the same time, the operation and scenario are matched in time. S20, through a preset time window, ensures that the cap is only triggered when an effective tap is made shortly after the refueling personnel / equipment arrives. This avoids the problem of the cap still opening even when the personnel are not in place but the tapping is not performed for a long time after the tapping is performed, and makes the refueling process more continuous.

[0092] In addition, such as Figure 6 As shown, Figure 6 This is a schematic diagram of a control device 600 for opening a vehicle fuel filler cap, provided in an embodiment of this disclosure. The device includes: The monitoring module 601 is used to monitor whether there is any tapping information indicating that the vehicle is being tapped at a preset position when the vehicle is in a preset position. The detection module 602 is used to detect the validity of the tapping information in response to the detection of tapping information at a preset position; The control module 603 is used to control the opening of the filler cap in response to a valid tapping signal.

[0093] In the above scheme, firstly, when the vehicle is in a preset position, it monitors whether there is any tapping information indicating that the preset position of the vehicle is being tapped; secondly, in response to the detection of tapping information indicating that the preset position is being tapped, the validity of the tapping information is checked; finally, in response to the valid tapping information, the fuel filler cap is controlled to open. In this way, through a coherent process of preset location limitation, tap information monitoring, and validity detection, intelligent control of the fuel filler cap opening is achieved. On the one hand, the preset location limitation ensures that the system only activates and responds in real refueling scenarios, avoiding the risk of accidental opening due to accidental touch or bumps in non-refueling scenarios such as vehicle driving or daily parking. This effectively protects the sealing of the vehicle's fuel system, preventing fuel evaporation and leakage, and the intrusion of foreign matter. At the same time, it is compatible with special models such as high-pressure fuel tanks, eliminating the need for the driver to perform additional pressure relief operations, thus ensuring the safety of the fuel system from the source of the scenario. On the other hand, using tapping as the trigger method, combined with validity detection, eliminates the cumbersome process of relying on the driver to manually unlock the cap. This allows refueling personnel to directly trigger the opening without waiting for the vehicle to come to a complete stop, significantly shortening the waiting time before refueling and alleviating gas station congestion. It can also distinguish between valid operations and irrelevant interference signals, avoiding accidental triggering and significantly improving operational convenience. In addition, this new tapping-based human-vehicle interaction method simplifies the operation process for gas station staff and reduces the operational burden on drivers, achieving a triple improvement in safety, convenience, and user experience, making the refueling process more efficient and worry-free.

[0094] In one specific embodiment, the detection module 602 is further configured to: In response to the detection of tapping information at a preset position, the tapping information is identified and the tapping parameters are determined; The system determines that the tapping information is valid if the tapping parameters match the preset tapping parameters.

[0095] In one specific embodiment, the preset tapping parameters may include at least a preset tapping rhythm, a preset number of taps, and a preset tapping force threshold. The detection module 602 is further configured to: The tapping information is deemed valid if the tapping parameters meet the preset tapping rhythm, preset number of taps, and preset tapping force threshold.

[0096] If the tapping parameters do not meet one of the preset tapping rhythm, preset tapping number, or preset tapping force threshold, the tapping information is determined to be invalid.

[0097] In one specific embodiment, the control device for opening the vehicle fuel filler cap also includes a statistics module; The statistics module is used to count the number of invalid keystrokes in response to invalid keystrokes. In response to an invalid number of times exceeding a preset threshold, the filler cap is locked for a preset time period.

[0098] In one specific embodiment, before controlling the opening of the fuel filler cap, the control device for opening the vehicle fuel filler cap further includes a first acquisition module; The first acquisition module is used to acquire the vehicle's status information, which is used to characterize the vehicle's operating status. In response to the status information meeting the safe opening conditions, the refueling cap is opened.

[0099] In one specific embodiment, the control device for opening the vehicle fuel filler cap further includes a second acquisition module: The second acquisition module is used to acquire the vehicle type; Determine the safe opening conditions based on vehicle type.

[0100] In one specific embodiment, the control device for opening the vehicle fuel filler cap further includes a third acquisition module: The third acquisition module is used to acquire the vehicle's environmental information in response to the vehicle being in a preset position; In response to the presence of a target object and / or refueling equipment in the environmental information, determine the time of occurrence of the target object and / or refueling equipment; The system controls the opening of the vehicle's fuel filler cap in response to the occurrence time and the effective tapping information being within a preset time window.
