Description

Technical Field

[0001] This application relates to the field of vehicle testing technology, and in particular to a hydrogen refueling method, apparatus, vehicle, medium, and procedure product. Background Technology

[0002] In response to the national call for carbon reduction and emission reduction, hydrogen fuel cell vehicles, which burn clean fuels, have emerged. However, hydrogen is a volatile and easily diffused hazardous gas, posing a high risk of fire and explosion. Therefore, hydrogen refueling in hydrogen fuel cell vehicles (including preparations before refueling and the refueling process) requires safety identification strategies to ensure hydrogen safety during refueling and thus prevent potential hazards.

[0003] In related technologies, sensors can be used to detect whether the hydrogen filling cap is open, and a controller can be used to switch the hydrogen filling cap to the open state. Then, infrared signals can be used to detect the status of the hydrogen filling gun and the hydrogen filling port to complete the hydrogen filling. Alternatively, an infrared signal can be generated when the hydrogen filling port cap is open, and then the infrared signal can be used for hydrogen filling, thereby improving the safety of hydrogen filling.

[0004] However, the relevant technologies cannot detect anomalies in the hydrogen refueling process in a timely manner, nor can they accurately identify the vehicle's hydrogen refueling request. They are inefficient and cannot meet the actual needs of users, and urgently need to be improved. Summary of the Invention

[0005] This application provides a hydrogen refueling method, apparatus, vehicle, medium, and program product to solve the problems in related technologies, such as the inability to detect anomalies in the hydrogen refueling process in a timely manner, the inability to accurately identify the vehicle's hydrogen refueling request, low efficiency, and inability to meet the actual needs of users.

[0006] The first aspect of this application provides a method for refueling a vehicle with hydrogen, comprising the following steps: obtaining a hydrogen refueling request from the vehicle; in response to the hydrogen refueling request, determining whether the vehicle meets preset hydrogen refueling safety conditions based on the overall vehicle status; if the vehicle meets the preset hydrogen refueling safety conditions, opening the hydrogen refueling port cover locking switch on the vehicle body, opening the hydrogen refueling port cover, so that the hydrogen refueling nozzle is connected to the hydrogen refueling port assembly for hydrogen refueling, and disconnecting the connection between the hydrogen refueling nozzle and the hydrogen refueling port assembly after detecting that hydrogen refueling is completed.

[0007] The above technical solution enables the determination of whether the vehicle's overall condition meets certain hydrogen refueling safety conditions before refueling. This effectively avoids refueling the vehicle in an unsafe state, reduces safety risks during refueling, and improves the overall safety and reliability of the refueling process. The opening of the refueling port cap based on the refueling request is convenient and efficient, enhancing the user experience. Refueling is performed after the refueling nozzle and refueling port assembly are connected, further improving the accuracy and efficiency of refueling. After refueling is completed, the connection is disconnected, reducing the complexity of user operations and making the refueling process more convenient.

[0008] Optionally, in one embodiment of this application, obtaining the vehicle's hydrogen refueling request includes: detecting whether a user has triggered a hydrogen refueling request switch, and generating the hydrogen refueling request when the triggering of the hydrogen refueling request switch is detected; or, collecting the actual location of the vehicle, and generating the hydrogen refueling request when the actual location is at a preset hydrogen refueling location and the distance between the hydrogen refueling nozzle and the hydrogen refueling port assembly is less than a preset threshold; or, identifying the vehicle's actual needs, and generating the hydrogen refueling request when the actual location is at a preset hydrogen refueling location and the actual needs are hydrogen refueling needs.

[0009] The above technical solutions enable the generation of hydrogen refueling requests in various ways, such as detecting whether the user has triggered a hydrogen refueling request switch, collecting the actual location of the vehicle and detecting the distance between the hydrogen refueling port and the hydrogen refueling port assembly, or identifying the actual needs and actual location of the vehicle.

[0011] The above technical solutions can set certain hydrogen refueling safety conditions, such as the vehicle being stationary, the hydrogen internal combustion engine being off, the power battery being in a high-voltage off-state, and the HMS having no fault codes. By setting certain hydrogen refueling safety conditions, the safety of the vehicle during the hydrogen refueling process can be ensured, the occurrence of accidents can be reduced, and the user experience can be improved.

[0012] Optionally, in one embodiment of this application, when the hydrogen refueling nozzle is connected to the hydrogen refueling port assembly for hydrogen refueling, the method further includes: detecting the pressure, temperature, and hydrogen leakage in the vehicle's hydrogen storage system; and stopping hydrogen refueling if any of the pressure, temperature, and hydrogen leakage meets a preset abnormal hydrogen refueling condition.

[0013] The above technical solution enables real-time monitoring of the safety of the hydrogen refueling process and timely cessation of refueling when the vehicle meets certain abnormal conditions, thereby improving the safety of hydrogen refueling, protecting the vehicle's hydrogen storage system, and reducing the risk of accidents.

[0014] Optionally, in one embodiment of this application, the method further includes: if the vehicle does not meet the preset hydrogen refueling safety conditions, generating hydrogen refueling failure information for the vehicle based on the vehicle status, and displaying the hydrogen refueling failure information to the user.

[0015] The above technical solution can generate hydrogen refueling failure information and display it to the user when the vehicle does not meet certain hydrogen refueling safety conditions. This helps the user to understand the vehicle's hydrogen refueling status and the reason for the failure in a timely manner, and thus guides the user to take the correct measures.

[0016] A second aspect of this application provides a hydrogen refueling device for a vehicle, comprising: an acquisition module for acquiring a hydrogen refueling request from the vehicle; a judgment module for determining, in response to the hydrogen refueling request, whether the vehicle meets preset hydrogen refueling safety conditions based on the overall vehicle status; and a hydrogen refueling module for, when the vehicle meets the preset hydrogen refueling safety conditions, opening the hydrogen refueling port cover locking switch on the vehicle body, opening the hydrogen refueling port cover so that the hydrogen refueling nozzle is connected to the hydrogen refueling port assembly for hydrogen refueling, and disconnecting the connection between the hydrogen refueling nozzle and the hydrogen refueling port assembly after detecting that hydrogen refueling is completed.

[0017] The above technical solution enables the determination of whether the vehicle's overall condition meets certain hydrogen refueling safety conditions before refueling. This effectively avoids refueling the vehicle in an unsafe state, reduces safety risks during refueling, and improves the overall safety and reliability of the refueling process. The opening of the refueling port cap based on the refueling request is convenient and efficient, enhancing the user experience. Refueling is performed after the refueling nozzle and refueling port assembly are connected, further improving the accuracy and efficiency of refueling. After refueling is completed, the connection is disconnected, reducing the complexity of user operations and making the refueling process more convenient.

[0018] Optionally, in one embodiment of this application, the acquisition module includes: a detection unit, configured to detect whether a user triggers a hydrogen refueling request switch, and generate a hydrogen refueling request when the triggering of the hydrogen refueling request switch is detected; or, a collection unit, configured to collect the actual location of the vehicle, and generate the hydrogen refueling request when the actual location is at a preset hydrogen refueling location and the distance between the hydrogen refueling nozzle and the hydrogen refueling port assembly is less than a preset threshold; or, an identification unit, configured to identify the actual needs of the vehicle, and generate the hydrogen refueling request when the actual location is at the preset hydrogen refueling location and the actual needs are hydrogen refueling needs.

[0019] The above technical solutions enable the generation of hydrogen refueling requests in various ways, such as detecting whether the user has triggered a hydrogen refueling request switch, collecting the actual location of the vehicle and detecting the distance between the hydrogen refueling port and the hydrogen refueling port assembly, or identifying the actual needs and actual location of the vehicle. By acquiring and responding to the vehicle's hydrogen refueling requests in multiple ways, the performance and efficiency of vehicle hydrogen refueling can be improved, and the personalized needs of users can be met more flexibly, thereby enhancing user satisfaction and loyalty.

[0020] Optionally, in one embodiment of this application, the preset hydrogen refueling safety conditions may include, but are not limited to: the vehicle being in a stopped state; the vehicle's hydrogen internal combustion engine being shut down; the vehicle's power battery being in a high-voltage off state; and the HMS having no fault codes.

[0021] The above technical solutions can set certain hydrogen refueling safety conditions, such as the vehicle being stationary, the hydrogen internal combustion engine being off, the power battery being in a high-voltage off-state, and the HMS having no fault codes. By setting certain hydrogen refueling safety conditions, the safety of the vehicle during the hydrogen refueling process can be ensured, the occurrence of accidents can be reduced, and the user experience can be improved.

[0022] Optionally, in one embodiment of this application, it further includes: a detection module, used to detect the pressure, temperature and hydrogen leakage in the hydrogen storage system of the vehicle when the hydrogen refueling gun is connected to the hydrogen refueling port assembly for hydrogen refueling; and a stop module, used to stop hydrogen refueling if any of the pressure, temperature and hydrogen leakage meets a preset hydrogen refueling abnormality condition.

[0023] The above technical solution enables real-time monitoring of the safety of the hydrogen refueling process and timely cessation of refueling when the vehicle meets certain abnormal conditions, thereby improving the safety of hydrogen refueling, protecting the vehicle's hydrogen storage system, and reducing the risk of accidents.

[0024] Optionally, in one embodiment of this application, it further includes: a prompting module, used to generate hydrogen refueling failure information for the vehicle based on the vehicle status when the vehicle does not meet the preset hydrogen refueling safety conditions, and to display the hydrogen refueling failure information to the user.

[0025] The above technical solution can generate hydrogen refueling failure information and display it to the user when the vehicle does not meet certain hydrogen refueling safety conditions. This helps the user to understand the vehicle's hydrogen refueling status and the reason for the failure in a timely manner, and thus guides the user to take the correct measures.

After refueling is completed, the connection is automatically disconnected. This effectively avoids refueling the vehicle under unsafe conditions, reduces safety risks during the hydrogen refueling process, improves the safety and reliability of the entire refueling process, and offers convenient and efficient operation, enhancing the user experience. Therefore, it solves the problems of related technologies, such as the inability to detect anomalies during the hydrogen refueling process in a timely manner, the inability to accurately identify the vehicle's hydrogen refueling request, low efficiency, and failure to meet the actual needs of users.

[0038] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0039] The following description, with reference to the accompanying drawings, outlines a hydrogen refueling method, apparatus, vehicle, medium, and program product according to embodiments of this application. Addressing the problems mentioned in the background art, such as the inability to promptly detect anomalies during the hydrogen refueling process, the inability to accurately identify vehicle refueling requests, low efficiency, and failure to meet user needs, this application provides a vehicle hydrogen refueling method. In this method, based on the acquired hydrogen refueling request and certain hydrogen refueling safety conditions, the hydrogen refueling port cover locking switch is opened, allowing the hydrogen refueling nozzle to connect with the hydrogen refueling port assembly for refueling. After refueling is complete, the connection is automatically disconnected. This effectively prevents hydrogen refueling under unsafe conditions, reduces safety risks during the refueling process, improves the safety and reliability of the entire refueling process, and offers convenient and efficient operation, enhancing the user experience. Therefore, this method solves the problems in related technologies, such as the inability to promptly detect anomalies during the hydrogen refueling process, the inability to accurately identify vehicle refueling requests, low efficiency, and failure to meet user needs.

[0040] Specifically, Figure 1 This is a flowchart of a hydrogen refueling method for a vehicle according to an embodiment of this application.

[0041] like Figure 1 As shown, the hydrogen refueling method for this vehicle includes the following steps:

[0042] In step S101, the vehicle's hydrogen refueling request is obtained.

[0043] Those skilled in the art will understand that, before obtaining a hydrogen refueling request from a vehicle, the embodiments of this application can determine whether the vehicle is a hydrogen fuel cell vehicle, and if the vehicle is a hydrogen fuel cell vehicle, obtain the hydrogen refueling request from the vehicle.

[0044] The vehicle safety identification system in this application embodiment may include, but is not limited to, a hydrogen refueling request switch, a geolocation receiver, an infrared signal trigger, an HCU (Hybrid Control Unit), an EMS (Engine Management System), an HMS (Hydrogen Management System), a BCM (Body Control Module), and instruments, etc. This application does not impose specific limitations.

[0045] Furthermore, in this embodiment of the application, the HMS can receive signal feedback from the hydrogen refueling port assembly, pressure sensor, temperature sensor, hydrogen concentration sensor, etc. in the hydrogen storage system, thereby obtaining the vehicle's hydrogen refueling request.

[0046] Optionally, in one embodiment of this application, obtaining a vehicle's hydrogen refueling request includes: detecting whether a user has triggered a hydrogen refueling request switch, and generating a hydrogen refueling request when the triggering of the hydrogen refueling request switch is detected; or, collecting the vehicle's actual location, and generating a hydrogen refueling request when the actual location is at a preset hydrogen refueling location and the distance between the hydrogen refueling nozzle and the hydrogen refueling port assembly is less than a preset threshold; or, identifying the vehicle's actual needs, and generating a hydrogen refueling request when the actual location is at a preset hydrogen refueling location and the actual needs are hydrogen refueling needs.

[0047] It is understood that the hydrogen refueling request switch in this application embodiment can be set inside the vehicle or through a mobile application (such as a vehicle management APP). When the vehicle needs hydrogen refueling, the user triggers the switch to generate a hydrogen refueling request.

[0048] In some embodiments, this application embodiment can generate a hydrogen refueling request when it detects that a user has triggered the hydrogen refueling request switch.

[0049] For example, in this embodiment of the application, a hydrogen refueling request switch is provided on the driver's side of the vehicle. When the vehicle needs to refuel with hydrogen, the user can press the hydrogen refueling request switch to generate a hydrogen refueling request, and then the HCU receives the hydrogen refueling request.

[0050] It is understood that embodiments of this application can collect the actual location of the vehicle in real time based on a geolocation receiver, such as GPS (Global Positioning System), or other positioning technologies.

[0051] In some embodiments, this application can determine whether the actual location of the vehicle is at a certain hydrogen refueling location, such as a hydrogen refueling station, based on GPS. This application does not impose specific limitations, and then generates a hydrogen refueling request based on the distance between the hydrogen refueling nozzle and the hydrogen refueling port assembly.

[0052] For example, in this embodiment of the application, when the actual location of the vehicle is a hydrogen refueling station and the distance between the hydrogen refueling gun and the hydrogen refueling port assembly is less than a certain threshold, the infrared signal trigger in the hydrogen refueling port assembly is triggered, generating a hydrogen refueling request, and sending the hydrogen refueling request to the HCU through the HMS.

[0053] In addition, the specific hydrogenation location and threshold can be set by those skilled in the art according to the actual situation, and this application does not impose specific restrictions.

[0054] It is understood that the embodiments of this application can collect various data of the vehicle in real time, such as the amount of hydrogen remaining in real time by an infrared signal trigger, thereby identifying the actual needs of the vehicle.

[0055] In some embodiments, this application generates a hydrogen refueling request when the vehicle's actual need is for hydrogen refueling and the vehicle's actual location is a certain hydrogen refueling location.

[0056] For example, in this embodiment of the application, when a vehicle needs to refuel with hydrogen, it enters a hydrogen refueling station. Based on the GPS recognition that the vehicle has entered the hydrogen refueling station, the refueling request is transmitted to the HCU.

[0057] In step S102, in response to the hydrogen refueling request, it is determined whether the vehicle meets the preset hydrogen refueling safety conditions based on the overall vehicle status.

[0058] It is understood that the vehicle status in the embodiments of this application may include, but is not limited to, whether the vehicle is stopped, whether the hydrogen internal combustion engine is stopped, whether the power battery is in a high-voltage off state, and whether the HMS is fault-free, etc. This application does not impose specific limitations.

[0059] In actual implementation, after responding to a vehicle's hydrogen refueling request, this embodiment of the application can determine whether the vehicle meets certain hydrogen refueling safety conditions based on the vehicle's overall condition, thereby ensuring the hydrogen refueling process is safe and avoiding potential risks. These certain hydrogen refueling safety conditions will be described below and will not be elaborated upon here.

[0060] For example, in this embodiment of the application, after the vehicle responds to the hydrogen refueling request, it can determine whether to refuel by judging whether the overall vehicle status meets certain hydrogen refueling safety conditions, such as whether the vehicle is stopped, whether the hydrogen internal combustion engine is stopped, whether the power battery is in a high-voltage off-state, and whether the HMS is fault-free.

[0061] Optionally, in one embodiment of this application, the preset hydrogen refueling safety conditions may include, but are not limited to, the following: the vehicle is in a stopped state; the vehicle's hydrogen internal combustion engine is off; the vehicle's power battery is in a high-voltage off state; and there are no fault codes in the HMS.

[0062] As can be seen from the above analysis, when responding to a vehicle's hydrogen refueling request, the embodiments of this application can determine the vehicle's status based on certain hydrogen refueling safety conditions, thereby achieving safe hydrogen refueling. These certain hydrogen refueling safety conditions may include, but are not limited to, the following: the vehicle is in a stopped state, the vehicle's hydrogen internal combustion engine is off, the vehicle's power battery is in a high-voltage off state, and the HMS has no fault codes.

[0063] The phrase "vehicle in a stopped state" can be understood as the vehicle being completely stopped before refueling with hydrogen, such as when the vehicle's speed is 0 km / h. If the vehicle is in motion, refueling with hydrogen is not possible.

[0064] The shutdown of a vehicle's hydrogen internal combustion engine can be understood as the hydrogen internal combustion engine being shut down and no longer running before refueling. If the vehicle's hydrogen internal combustion engine is not shut down, refueling cannot be performed.

[0065] The fact that a vehicle's power battery is in a high-voltage, de-energized state means that the power battery is in a safe state before adding hydrogen. This means that the vehicle's power battery should be in a high-voltage, de-energized state to avoid dangerous situations such as electric shock or short circuit during the hydrogen refueling process. If the vehicle's power battery is in a high-voltage, de-energized state, hydrogen refueling cannot be performed.

[0066] The absence of fault codes in the HMS means that before adding hydrogen, it is necessary to check whether the HMS has reported any faults. If so, hydrogen can only be added after these faults have been resolved.

[0067] Furthermore, in the embodiments of this application, if any one of the following conditions is not met, such as the vehicle stopping, the hydrogen internal combustion engine stopping, the high voltage of the power battery being de-energized, or the HMS having no fault codes, hydrogen refueling cannot be performed.

[0068] In step S103, if the vehicle meets the preset hydrogen refueling safety conditions, the hydrogen refueling port cover locking switch on the vehicle body is opened, the hydrogen refueling port cover is opened, so that the hydrogen refueling nozzle is connected to the hydrogen refueling port assembly for hydrogen refueling, and after the hydrogen refueling is detected to be completed, the connection between the hydrogen refueling nozzle and the hydrogen refueling port assembly is disconnected.

[0069] It is understood that after the hydrogen filling port cover locking switch is opened, the hydrogen filling port cover can be opened automatically or manually. The specific settings can be made by those skilled in the art according to the actual situation, and this application does not impose any specific restrictions.

[0070] As one possible implementation method, in this application embodiment, when the vehicle meets certain hydrogen refueling safety conditions, the hydrogen refueling port cover locking switch on the vehicle body can be opened, thereby opening the hydrogen refueling port cover, allowing the hydrogen refueling nozzle to connect with the hydrogen refueling port assembly for hydrogen refueling, and disconnecting the connection between the hydrogen refueling nozzle and the hydrogen refueling port assembly after hydrogen refueling is completed.

[0071] For example, in this embodiment of the application, when the HCU determines that the vehicle meets certain hydrogen refueling safety conditions, it sends a command to the BCM. The BCM controls the hydrogen refueling port cover lock switch on the vehicle body to open, allowing the hydrogen refueling port cover to open, thereby connecting the hydrogen refueling nozzle with the hydrogen refueling port assembly for hydrogen refueling. When hydrogen refueling begins, the infrared signal trigger on the hydrogen refueling port assembly will feed back the current hydrogen storage information of the hydrogen storage system to the hydrogen refueling nozzle via infrared signal. The hydrogen refueling nozzle refuels based on the received information. During the hydrogen refueling process, the infrared signal trigger on the hydrogen refueling port assembly continuously interacts with the hydrogen refueling nozzle to determine whether hydrogen refueling is complete. Then, after hydrogen refueling is completed, the connection between the hydrogen refueling nozzle and the hydrogen refueling port assembly is disconnected.

[0072] Optionally, in one embodiment of this application, when the hydrogen refueling nozzle is connected to the hydrogen refueling port assembly for hydrogen refueling, the method further includes: detecting the pressure, temperature, and hydrogen leakage in the vehicle's hydrogen storage system; and stopping hydrogen refueling if any of the pressure, temperature, and hydrogen leakage meets a preset abnormal hydrogen refueling condition.

[0073] Those skilled in the art will understand that, in the embodiments of this application, the pressure, temperature and hydrogen leakage of the vehicle's hydrogen storage system can be collected in real time during hydrogen refueling, and hydrogen refueling will be stopped when any of these conditions meet certain abnormal conditions.

[0074] Furthermore, in this embodiment of the application, when hydrogen refueling is stopped, a stop hydrogen refueling signal can be generated, such as a voice signal, a light signal, or a vibration signal light, to promptly inform the user that continuing hydrogen refueling poses a certain risk, thereby stopping hydrogen refueling in a timely and accurate manner and avoiding the occurrence of unsafe accidents.

[0075] Here, pressure can be understood as whether the hydrogen pressure in the hydrogen storage system is within a certain safe pressure range. The certain safe pressure range can be set by those skilled in the art according to the actual situation, and this application does not impose specific restrictions.

[0076] Temperature can be understood as whether the temperature within the hydrogen storage system is within a certain safe temperature range. This certain safe temperature range can be set by those skilled in the art according to the actual situation, and this application does not impose any specific restrictions.

[0077] Hydrogen leakage can be understood as whether hydrogen is leaking from the hydrogen storage system or the hydrogen refueling port.

[0078] Abnormal conditions for hydrogenation may include, but are not limited to, any of the following: pressure exceeding the safe pressure range, temperature exceeding the safe temperature range, or hydrogen leakage.

[0079] For example, in the hydrogen refueling process of this application embodiment, the injection of hydrogen will cause changes in the pressure, temperature and hydrogen leakage information of the hydrogen storage system. The HMS detects this information in real time. Once certain abnormal hydrogen refueling conditions are met, it immediately sends a stop hydrogen refueling signal to the hydrogen refueling gun through an infrared signal trigger to stop hydrogen refueling in time and ensure hydrogen refueling safety.

[0080] Optionally, in one embodiment of this application, the method further includes: if the vehicle does not meet the preset hydrogen refueling safety conditions, generating hydrogen refueling failure information based on the vehicle status and displaying the hydrogen refueling failure information to the user.

[0081] As one possible implementation method, embodiments of this application can generate corresponding hydrogen refueling failure information and send it to the user when the vehicle does not meet certain hydrogen refueling safety conditions, so that the user can understand the reason for the hydrogen refueling failure in a timely manner and take corresponding measures.

[0082] The hydrogenation failure message can be, but is not limited to, voice messages, text messages, etc., and can be set by those skilled in the art according to the actual situation. This application does not impose specific restrictions.

[0083] In some embodiments, this application can generate hydrogen refueling failure information based on the vehicle status, such as if the vehicle is not stopped, such as "Hello user, the vehicle is not stopped and does not meet certain hydrogen refueling safety conditions, hydrogen refueling failed, please stop immediately," and then provide a voice reminder or display screen to the user, so that the user can understand the reason for the hydrogen refueling failure and take appropriate measures.

[0084] In some embodiments, this application can generate hydrogen refueling failure information based on the vehicle status, such as the vehicle's hydrogen internal combustion engine not being shut down, such as "Hello user, the vehicle's hydrogen internal combustion engine is not shut down, and certain hydrogen refueling safety conditions are not met, hydrogen refueling has failed, please shut down the engine in time," and then provide a voice reminder or display screen to the user, so that the user can understand the reason for the hydrogen refueling failure in time and take appropriate measures.

[0085] In some embodiments, this application can generate hydrogen refueling failure information based on the vehicle status, such as the vehicle's power battery being at high voltage and not de-energized, such as "Hello user, the vehicle's power battery is at high voltage and not de-energized, which does not meet certain hydrogen refueling safety conditions, and hydrogen refueling has failed. Please de-energize in time." Then, it can provide a voice reminder or display screen to the user, showing the hydrogen refueling failure information to the user so that the user can understand the reason for the hydrogen refueling failure in time and take appropriate measures.

[0086] In some embodiments, this application can generate hydrogen refueling failure information based on the vehicle status, such as HMS malfunction, such as "Hello user, HMS malfunction, certain hydrogen refueling safety conditions are not met, hydrogen refueling failed, please check HMS", and then provide a voice reminder or display screen to the user, so that the user can understand the reason for the hydrogen refueling failure in a timely manner and take corresponding measures.

[0087] The working principle of the hydrogen refueling method for vehicles proposed in this application will be described in detail below with reference to a specific embodiment.

[0088] in, Figure 2 This is a flowchart illustrating the working principle of a hydrogen refueling method for a vehicle according to an embodiment of this application.

[0089] Step S201: Based on the acquisition of at least one hydrogen refueling request, such as the vehicle's actual location, hydrogen refueling request switch, and the vehicle's actual needs, generate a hydrogen refueling request and receive the hydrogen refueling request through the HCU.

[0093] Step S205: Determine if the HMS has no fault codes. If the HMS has no fault codes, proceed to step S206; otherwise, proceed to step S209.

[0094] Step S206: The vehicle is not stopped and cannot be refueled with hydrogen. Please stop driving.

[0095] Step S207: The message indicates that the hydrogen internal combustion engine is not shut down and cannot be refueled with hydrogen. Please stop the hydrogen internal combustion engine.

[0096] Step S208: The vehicle's high-voltage power supply is not turned off, so hydrogen cannot be refueled. Please turn off the high-voltage power supply.

[0097] Step S209: A message indicates a hydrogen storage system malfunction and hydrogen refueling is unavailable. Please check the hydrogen storage system. Proceed to S210.

[0102] Step S214: Determine whether certain abnormal hydrogenation conditions are met. If the abnormal hydrogenation conditions are met, proceed to step S215; otherwise, proceed to step S212.

[0103] Step S215: The infrared signal trigger sends a stop hydrogen refueling signal to the hydrogen refueling gun, and then proceeds to step S217.

[0104] Step S216: Determine whether hydrogenation is complete. If hydrogenation is complete, proceed to step S217; otherwise, proceed to step S213.

[0105] Step S217: Stop hydrogen addition.

[0106] The hydrogen refueling method for vehicles proposed in this application can obtain a hydrogen refueling request and, based on certain hydrogen refueling safety conditions, open the hydrogen refueling port cover locking switch to connect the hydrogen refueling nozzle to the hydrogen refueling port assembly for refueling. After refueling is completed, the connection is automatically disconnected. This effectively avoids refueling the vehicle under unsafe conditions, reduces safety risks during the refueling process, improves the safety and reliability of the entire refueling process, and offers convenient and efficient operation, enhancing the user experience. Therefore, it solves the problems in related technologies, such as the inability to detect anomalies during the refueling process in a timely manner, the inability to accurately identify the vehicle's hydrogen refueling request, low efficiency, and failure to meet the actual needs of users.

[0107] Next, a hydrogen refueling device for a vehicle according to an embodiment of this application is described with reference to the accompanying drawings.

[0108] Figure 3 This is a block diagram of a hydrogen refueling device for a vehicle provided according to an embodiment of this application.

[0109] like Figure 3 As shown, the hydrogen refueling device 30 of the vehicle includes: an acquisition module 100, a judgment module 200, and a hydrogen refueling module 300.

[0110] The acquisition module 100 is used to acquire the hydrogen refueling request from the vehicle.

[0111] The judgment module 200 is used to respond to a hydrogen refueling request and determine whether the vehicle meets the preset hydrogen refueling safety conditions based on the overall vehicle status.

[0112] The hydrogen refueling module 300 is used to open the hydrogen refueling port cover locking switch on the vehicle body when the vehicle meets the preset hydrogen refueling safety conditions, open the hydrogen refueling port cover, so that the hydrogen refueling nozzle can be connected to the hydrogen refueling port assembly for hydrogen refueling, and disconnect the connection between the hydrogen refueling nozzle and the hydrogen refueling port assembly after detecting that hydrogen refueling is completed.

[0113] Optionally, in one embodiment of this application, the acquisition module 100 includes: a detection unit, a collection unit, or an identification unit.

[0114] The detection unit is used to detect whether the user has triggered the hydrogen refueling request switch, and generates a hydrogen refueling request when the triggering of the hydrogen refueling request switch is detected.

[0115] The data acquisition unit is used to acquire the actual location of the vehicle and generate a hydrogen refueling request when the actual location is at a preset hydrogen refueling position and the distance between the hydrogen refueling nozzle and the hydrogen refueling port assembly is less than a preset threshold.

[0116] The identification unit is used to identify the actual needs of the vehicle and generate a hydrogen refueling request when the actual location is a preset hydrogen refueling location and the actual need is for hydrogen refueling.

[0117] Optionally, in one embodiment of this application, the preset hydrogen refueling safety conditions may include, but are not limited to, the following: the vehicle is in a stopped state; the vehicle's hydrogen internal combustion engine is off; the vehicle's power battery is in a high-voltage off state; and there are no fault codes in the HMS.

[0118] Optionally, in one embodiment of this application, it further includes a detection module and a stop module.

[0121] Optionally, in one embodiment of this application, a prompting module is also included.

[0122] The notification module is used to generate hydrogen refueling failure information based on the vehicle's status when the vehicle does not meet the preset hydrogen refueling safety conditions, and then display the hydrogen refueling failure information to the user.

[0123] It should be noted that the explanation of the above-described embodiment of the hydrogen refueling method for vehicles also applies to the hydrogen refueling device for the vehicle in this embodiment, and will not be repeated here.

[0124] The hydrogen refueling device for vehicles proposed in this application can, upon receiving a hydrogen refueling request and based on certain hydrogen refueling safety conditions, open the hydrogen refueling port cover locking switch, allowing the hydrogen refueling nozzle to connect with the hydrogen refueling port assembly for refueling. After refueling is complete, the connection is automatically disconnected. This effectively prevents hydrogen refueling from occurring in an unsafe vehicle condition, reduces safety risks during the refueling process, improves the safety and reliability of the entire refueling process, and offers convenient and efficient operation, enhancing the user experience. Therefore, it solves the problems in related technologies, such as the inability to promptly detect anomalies during the refueling process, the inability to accurately identify vehicle refueling requests, low efficiency, and failure to meet actual user needs.
