Description

Technical Field

[0001] This application relates to the field of vehicles, and more specifically, to a method, system, vehicle, and storage medium for locking a hydrogen refueling cap in the field of vehicles. Background Technology

[0002] Currently, the automotive industry is in a transitional phase from traditional fuel vehicles to new energy vehicles, with hybrid and pure electric vehicles being the main types of new energy vehicles. However, the range and charging time of pure electric vehicles have limited their widespread application to some extent, while hydrogen fuel cell vehicles have shown good performance, requiring only 3 to 5 minutes to refuel and achieving a range of up to 800 kilometers.

[0003] However, existing hydrogen fuel cell vehicles pose a significant risk of explosion if hydrogen leaks, making them extremely unsafe. Summary of the Invention

[0004] This application provides a method, system, vehicle, and storage medium for locking a hydrogen refueling port cap. This method can effectively reduce the risk of explosions caused by hydrogen leakage in vehicles, reduce the occurrence of hazards, and enhance the safety of vehicle use.

[0005] In a first aspect, a method for controlling the locking of a hydrogen refueling port cover is provided. The method includes: acquiring the status information of the vehicle when the vehicle has completed a hydrogen refueling operation; determining, based on the vehicle status information, whether a preset condition for controlling the electronic lock of the hydrogen refueling port cover to be in a locked state is met; and controlling the electronic lock of the hydrogen refueling port cover to be in a locked state when the preset condition is met.

[0006] The above technical solution, upon detecting that the vehicle has completed the hydrogen refueling operation, acquires the vehicle's status information; based on the vehicle's status information, it determines whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in the locked state are met; by acquiring the vehicle's status information, the current state of the vehicle can be determined, thereby more accurately determining whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in the locked state are met. If the preset conditions are met, the electronic lock of the hydrogen refueling cap is controlled to be in the locked state, which can effectively prevent the hydrogen refueling cap from accidentally opening due to accidental contact after the vehicle has finished refueling and closed, thereby effectively reducing the risk of explosion due to hydrogen leakage, reducing the occurrence of hazards, and enhancing the safety of vehicle use.

[0007] In conjunction with the first aspect, in some implementations of the first aspect, the vehicle's state information includes the vehicle's door state and power system state. Determining whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met based on the vehicle's state information includes: if the door state is determined to be unlocked, detecting whether the power system state has received a power-on request; if the power system state is determined to have received the power-on request, then determining that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met.

[0008] In combination with the first aspect and the above implementation methods, in some implementation methods of the first aspect, the vehicle's status information includes the vehicle's door status. The determination of whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met based on the vehicle's status information includes: if it is determined that the door status is locked, then it is determined that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met.

[0009] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, the vehicle's status information includes the vehicle's door status and / or the power system status. The determination of whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state based on the vehicle's status information includes: if it is determined that the vehicle's door status is locked and / or the power system status is a state that has received a power-on request, then it is determined that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met.

[0010] The above technical solution acquires the vehicle door status and / or power system status, and based on these statuses, determines whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met. By analyzing the vehicle door status and power system status, the user's driving needs can be determined. Whether there is no driving need or a driving need exists, hydrogen leakage must be prevented. Therefore, when the vehicle door status is locked and / or the power system status is in a state of receiving a power-on request, determining that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met can more effectively prevent hydrogen leakage and thus ensure vehicle safety.

[0011] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, before obtaining the vehicle's status information, the method further includes: obtaining the current status of the vehicle's hydrogen storage system; when it is detected that the current status of the hydrogen storage system has switched from a hydrogen refueling state to a standby state, detecting whether the hydrogen refueling cap is in a closed state; determining whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met based on the vehicle's status information includes: when it is detected that the hydrogen refueling cap is in a closed state, determining whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met based on the vehicle's status information.

[0012] The above technical solution, before obtaining the vehicle's status information, can first determine whether the current state of the hydrogen storage system has switched from hydrogen refueling to standby. If the current state of the hydrogen storage system has switched from hydrogen refueling to standby, it indicates that the hydrogen refueling operation has been completed. Since the electronic lock of the hydrogen refueling port cap can only be locked when the cap is closed, it is necessary to ensure that the cap is closed before determining whether the preset conditions for locking the electronic lock are met. This determination method more reasonably identifies whether the preset conditions for locking the electronic lock are met, thereby more effectively preventing hydrogen leakage.

[0013] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, when the current state of the hydrogen storage system is detected to have switched from the hydrogen refueling state to the standby state, the method further includes: if no request to control the power mode of the vehicle to switch to the on mode is received within a preset time period, then the power mode of the vehicle is controlled to be in the off mode.

[0014] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, controlling the power mode of the vehicle to be in the off mode includes: obtaining the current gear of the vehicle; if the current gear is not in the parking gear, controlling the current gear of the vehicle to switch to the parking gear, and controlling the power mode of the vehicle to be in the off mode.

[0015] The above-described technical solution promptly receives requests for vehicle power-on or power-off after the hydrogen refueling operation is completed. If no request to switch the vehicle's power mode to on mode is received within a preset time period, the vehicle's power mode is switched to off mode, effectively reducing battery depletion. Furthermore, before switching the vehicle's power mode to off mode, the current gear is shifted to park, preventing the vehicle from rolling after power loss and further ensuring vehicle safety.

[0016] Secondly, a device for controlling the locking of a hydrogen refueling port cap is provided. The device includes: an acquisition module for acquiring the status information of a vehicle when the vehicle has completed a hydrogen refueling operation; a judgment module for determining, based on the vehicle status information, whether a preset condition for controlling the electronic lock of the hydrogen refueling port cap to be in a locked state is met; and a control module for controlling the electronic lock of the hydrogen refueling port cap to be in a locked state when it is determined that the preset condition is met.

[0017] In conjunction with the second aspect, in some implementations of the second aspect, the vehicle's status information includes the vehicle's door status and the power system status. The judgment module is specifically used to: when it is determined that the door status is unlocked, detect whether the power system status is a state that has received a power-on request; if it is determined that the power system status is a state that has received the power-on request, then determine that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in the locked state are currently met.

[0018] In combination with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the vehicle's status information includes the vehicle's door status. The judgment module is specifically used to: if it is determined that the door status is locked, then determine that the preset conditions for controlling the electronic lock of the hydrogen refueling port cover to be locked are met.

[0019] In combination with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the vehicle's status information includes the vehicle's door status and / or the power system status. The judgment module is specifically used to: if it is determined that the vehicle's door status is locked and / or the power system status is that a power-on request has been received, then determine that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are currently met.

[0020] In conjunction with the second aspect and the above-described implementations, in some implementations of the second aspect, the device further includes a detection module, which is specifically used to: acquire the current state of the vehicle's hydrogen storage system; when the current state of the hydrogen storage system is detected to have switched from a hydrogen refueling state to a standby state, detect whether the hydrogen refueling port cap is in a closed state; the judgment module is also used to: when the hydrogen refueling port cap is detected to be in a closed state, determine, based on the vehicle's state information, whether the preset conditions for controlling the electronic lock of the hydrogen refueling port cap to be in a locked state are met.

[0021] In conjunction with the second aspect and the above-described implementations, in some implementations of the second aspect, the device further includes a second control module, which is configured to: if no request to control the power mode of the vehicle to switch to the on mode is received within a preset time period, control the power mode of the vehicle to be in the off mode.

[0022] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the second control module is specifically used to: obtain the current gear of the vehicle; if the current gear is not in the parking gear, control the current gear of the vehicle to switch to the parking gear, and control the power mode of the vehicle to be in the off mode.

[0023] Thirdly, a vehicle is provided, including a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, causing the vehicle to perform the method of controlling the locking of the hydrogen refueling port cover as described in the first aspect and any possible implementation thereof.

[0024] Fourthly, a computer program product is provided, comprising: computer program code, which, when run on a computer, causes the computer to perform the method for controlling the locking of the hydrogen refueling port cap as described in the first aspect and any possible implementation thereof.

[0025] Fifthly, a computer-readable storage medium is provided that stores computer program code, which, when executed on a computer, causes the computer to perform the method for controlling the locking of the hydrogen refueling port cap as described in the first aspect and any possible implementation thereof.

[0029] Figure 4 This is a schematic diagram of the structure of a vehicle provided in an embodiment of this application. Detailed Implementation

[0030] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0031] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0032] Currently, the automotive industry is in a transitional phase from traditional fuel-powered vehicles to new energy vehicles, with hybrid and pure electric vehicles being the main types of new energy vehicles. However, the range and charging time of pure electric vehicles have limited their widespread application to some extent, while hydrogen fuel cell vehicles have shown good performance, requiring only 3 to 5 minutes to refuel and achieving a range of up to 800 kilometers.

[0033] However, existing hydrogen fuel cell vehicles pose a significant risk of explosion if hydrogen leaks, making them extremely unsafe.

[0034] Specifically, currently, after refueling a hydrogen fuel cell vehicle, the operator closes the refueling port cap. However, the cap does not automatically lock; it only locks when the vehicle is locked or all doors are locked. If the cap fails to lock automatically, it may be accidentally touched or left unclosed after refueling. When the driver gets in and powers on the vehicle, a message will appear stating "Refueling port cap not closed, vehicle cannot power on." The driver cannot drive the vehicle normally and must get out to close the cap before powering on and driving, which is extremely inconvenient. Furthermore, an unclosed cap can easily cause hydrogen leakage, posing a risk of explosion and posing a significant safety hazard.

[0035] To address the aforementioned technical problems, this application provides a method for controlling the locking of a hydrogen refueling port cover. The method is executed by a vehicle, specifically a controller within the vehicle.

[0036] Figure 1 This is a schematic flowchart illustrating a method for controlling the locking of a hydrogenation port cover according to an embodiment of this application.

[0037] For example, such as Figure 1 As shown, the method 100 includes:

[0038] S101: Upon detecting that the vehicle has completed the hydrogen refueling operation, obtain the vehicle's status information.

[0039] S102, based on the vehicle's status information, determine whether the preset conditions for controlling the electronic lock of the hydrogen refueling port cover to be in the locked state are met.

[0040] For example, if it is determined that the preset condition is met, then S103 is executed; if it is determined that the preset condition is not met, then the process ends.

[0041] S103, the electronic lock controlling the hydrogen filling port cover is in the locked state.

[0042] This application provides a method for controlling the locking of a hydrogen refueling port cap. Upon detecting that a vehicle has completed hydrogen refueling, the method acquires the vehicle's status information. Based on this status information, it determines whether a preset condition for locking the electronic lock of the hydrogen refueling port cap is met. By acquiring the vehicle's status information, the current state of the vehicle can be determined, allowing for a more accurate assessment of whether the preset condition for locking the electronic lock of the hydrogen refueling port cap is met. If the preset condition is met, the electronic lock of the hydrogen refueling port cap is locked. This method effectively prevents the hydrogen refueling port cap from accidentally opening after refueling, thereby significantly reducing the risk of explosions due to hydrogen leakage, minimizing hazards, and enhancing vehicle safety.

[0043] The following is about Figure 1 The implementation methods of each step in the illustrated embodiment are explained in detail below:

[0044] Regarding S101 above, it is understood that after the vehicle completes the hydrogen refueling operation, the Hydrogen Control System (HMS) will control the hydrogen storage system to exit the hydrogen refueling state, and the Body Control Module (BCM) in the vehicle can determine whether the current hydrogen refueling operation for the vehicle has ended based on the change in the state of the hydrogen storage system.

[0045] If the operator fails to close the hydrogen refueling cap promptly after completing the hydrogen refueling operation, the electronic lock on the cap will not be locked. Therefore, before determining whether the vehicle meets the preset conditions for locking the electronic lock on the hydrogen refueling cap, it must be ensured that the hydrogen refueling operation has been completed and the hydrogen refueling cap has been closed.

[0046] In one possible implementation, before acquiring the vehicle's status information, the method further includes: acquiring the current status of the vehicle's hydrogen storage system; detecting whether the hydrogen refueling cap is closed when the current status of the hydrogen storage system is detected to have switched from a hydrogen refueling state to a standby state; and determining whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met based on the vehicle's status information, including: when the hydrogen refueling cap is detected to be closed, determining whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met based on the vehicle's status information.

[0047] Under normal circumstances, after a vehicle completes hydrogen refueling, the HMS (Hydrogen Management System) will switch the hydrogen storage system from refueling mode to standby mode. Simultaneously, the HMS will send the current status of the hydrogen storage system to the BCM (Battery Management System). The BCM can then determine whether the vehicle has completed the refueling operation based on the current status of the hydrogen storage system. If the BCM determines that the hydrogen storage system has switched from refueling mode to standby mode, it can confirm that the vehicle has completed the refueling operation.

[0048] Furthermore, as mentioned above, after confirming that the vehicle has completed the hydrogen refueling operation, it is also necessary to ensure that the hydrogen refueling port cap is closed. If the hydrogen refueling port cap is not closed, the electronic lock of the hydrogen refueling port cap cannot be controlled.

[0049] Understandably, once it is determined that the vehicle has completed the hydrogen refueling operation and the hydrogen refueling cap is closed, the vehicle's current status information can be obtained. Specifically, the aforementioned status information can be used to characterize the vehicle's current status, including the vehicle's power-on / off status.

[0050] For example, the status information may include the vehicle door status and the power-on / off status of the powertrain.

[0051] Regarding S102 above, it is understandable that after a vehicle completes hydrogen refueling, the refueling cap needs to be closed promptly to prevent hydrogen leakage. Keeping the electronic lock on the refueling cap in the locked state prevents accidental opening and effectively avoids hydrogen leakage. Therefore, it is necessary to keep the electronic lock on the refueling cap in the locked state promptly. Before locking the electronic lock, it is possible to determine, based on the vehicle's status information obtained above, whether the vehicle currently meets the preset conditions for keeping the electronic lock on the refueling cap in the locked state.

[0052] In one possible implementation, the vehicle's status information includes the vehicle's door status. The determination of whether the preset conditions for controlling the electronic lock of the hydrogen refueling port cover to be in a locked state are met based on the vehicle's status information includes: if the door status is determined to be locked, then the preset conditions for controlling the electronic lock of the hydrogen refueling port cover to be in a locked state are determined.

[0053] It is understood that the aforementioned door states specifically refer to the states of all four doors of the vehicle, including locked, closed, and open states. Specifically, a locked state means the electronic lock on the door is fully locked. When the door is locked, the user can unlock it using the key or by pressing the corresponding unlock button inside the vehicle. A closed state means the door is closed but the electronic lock is not engaged. When the vehicle is closed, the user can unlock the door using the door handle without needing to unlock the vehicle. An open state means the door is in the open position.

[0054] Furthermore, users can lock the doors by pressing the key or the corresponding lock button inside the vehicle. Alternatively, the vehicle can lock the doors to ensure driving safety when the vehicle speed is greater than or equal to a preset speed threshold.

[0055] If the vehicle door is confirmed to be locked, this could be due to several reasons: the driver may have locked the door using the key after refueling without intending to drive; the driver may have locked the door using an in-vehicle button after refueling; or the vehicle may have locked the door when its speed is greater than or equal to a preset speed threshold. In summary, regardless of the driver's intent to drive, if the door is confirmed to be locked, it indicates that the vehicle door status meets the preset conditions for locking the electronic lock on the refueling port cap.

[0056] If the vehicle door is not locked, there is a risk of hydrogen leakage if the electronic lock on the hydrogen refueling cap is not kept in place. Furthermore, if the vehicle's speed is below the preset speed threshold, the doors will not automatically lock, meaning they will remain unlocked. In this situation, the vehicle cannot promptly lock the electronic lock on the hydrogen refueling cap, potentially allowing it to open, which is extremely unsafe.

[0057] Therefore, the electronic lock on the hydrogen refueling port cap can be kept in a locked state when the vehicle's power system requests power. It should be understood that when the vehicle's power system requests power, it means the vehicle will not be refueling at that time, and the electronic lock on the hydrogen refueling port cap can be directly kept locked.

[0058] In one possible implementation, the vehicle's status information includes the status of the vehicle's doors and the status of the power system. Determining whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met based on the vehicle's status information includes: if the door status is determined to be unlocked, detecting whether the power system status is a state that has received a power-on request; if the power system status is determined to be a state that has received the power-on request, then determining that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met.

[0059] Understandably, as mentioned earlier, if the vehicle door is determined to be unlocked, it could be either closed or open. This could be because the vehicle needs to be refueled with hydrogen again, hence the door isn't locked. Specifically, if the door isn't locked, the electronic lock on the hydrogen refueling cap is also not locked, allowing the operator to reopen the cap and refuel. Alternatively, it could be that the user needs to use the vehicle after refueling, so the door isn't locked; the user needs to open the door to get in and drive, naturally without locking the door.

[0060] Furthermore, if the vehicle needs to be refueled with hydrogen again, there is no need to control the electronic lock of the hydrogen refueling cap. If the user needs to continue using the vehicle after refueling, the electronic lock of the hydrogen refueling cap can be controlled to ensure driving safety.

[0061] Understandably, during the hydrogen refueling process, the vehicle's power mode is in non-power-on mode, and the power system mode is in standby mode.

[0062] Specifically, non-power-on modes can include the vehicle's power supply being in OFF mode, ACC mode, and CRANK mode. OFF mode corresponds to "LOCK" in the ignition key, indicating that the vehicle's power is off, and the Controller Area Network (CAN) is generally in a dormant state. ACC mode corresponds to "ACC" in the ignition key, indicating that the vehicle is powered on, the CAN network is awakened and begins transmitting signals, but the engine is not started, and the vehicle is essentially connected to a 12V power supply. CRANK mode corresponds to "START" in the ignition key, indicating that the engine is ignited. In practice, turning the key to "START" and waiting for successful engine ignition before the ignition key returns to "ON" indicates that the vehicle's engine has started.

[0063] The aforementioned power system may include multiple control devices such as a starter motor, a drive motor, a DC-to-DC converter (DCDC), and a battery management system. If all these control devices are in standby mode, the power system mode can be determined to be standby mode, which also indicates that the power system is not powered on. Hydrogen refueling is permitted when the power system is in standby mode.

[0064] Furthermore, during hydrogen refueling, the vehicle's power mode is in non-power-on mode, and the power system mode is in standby mode. Therefore, if the vehicle doors are unlocked, but the vehicle receives a power-on request for the power system, it is determined that the user needs to use the vehicle, meaning the preset condition for the electronic lock controlling the hydrogen refueling port to be locked is met.

[0065] In one possible scenario, the vehicle may receive a power-on request for the powertrain even when the vehicle doors are locked.

[0066] In one possible implementation, the vehicle's status information includes the status of the vehicle's doors and / or the status of the power system. The determination of whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met based on the vehicle's status information includes: if it is determined that the vehicle's doors are in a locked state and / or the power system is in a state of receiving a power-on request, then it is determined that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met.

[0067] It is understandable that, as mentioned above, there may be situations where the vehicle door is locked and a power-on request to the power system is received simultaneously. In such cases, it can be determined that the preset conditions for the electronic lock controlling the hydrogen refueling cap to be in a locked state are met.

[0068] In other words, regardless of whether the vehicle door is locked or unlocked, when the vehicle receives a power-on request for the power system, it can be determined that the preset conditions for the electronic lock controlling the hydrogen refueling cap to be locked are met.

[0069] The above method obtains the vehicle's door status and / or power system status, and based on these statuses, determines whether the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met. By analyzing the vehicle's door status and power system status, the user's driving needs can be determined. Whether there is no driving need or a driving need exists, hydrogen leakage must be prevented. Therefore, when the vehicle's door status is locked and / or the power system status is in a state of receiving a power-on request, determining that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are met can more effectively prevent hydrogen leakage and thus ensure vehicle safety.

[0070] Regarding S103, it is understood that, under the condition that the above preset conditions are met, the electronic lock of the hydrogen filling port can be controlled to be in a locked state to prevent hydrogen leakage.

[0071] For example, if it is determined that the vehicle door is locked, the electronic lock of the hydrogen refueling cap can be locked. If it is determined that the vehicle door is not locked, but the vehicle's powertrain is in a state of receiving a power-on request, the electronic lock of the hydrogen refueling cap can be locked. If the vehicle door is locked and the vehicle's powertrain is in a state of receiving a power-on request, the electronic lock of the hydrogen refueling cap can also be locked.

[0072] Furthermore, after determining that the hydrogen storage system has switched from the hydrogen refueling state to the standby state, in order to ensure vehicle safety, in addition to keeping the electronic lock of the hydrogen refueling cap in the locked state, it is also possible to determine whether to control the vehicle to power on or off based on the current state of the vehicle.

[0073] Specifically, after the vehicle completes hydrogen refueling, if no one operates the vehicle within a preset time period, the vehicle's power mode may remain in a non-power-on mode for an extended period, during which the vehicle remains in an awake state. While the vehicle is in an awake state and the battery relays are not closed, the vehicle is primarily powered by the battery. If the vehicle is not used for a long time, the battery will continuously deplete its charge, potentially leading to battery depletion. Therefore, after determining that the hydrogen storage system has transitioned from refueling to standby mode, the decision to power on or off the vehicle can be made based on its current status.

[0074] In one possible implementation, when the current state of the hydrogen storage system is detected to have switched from hydrogen refueling state to standby state, the method further includes: if no request to switch the power mode of the vehicle to the on mode is received within a preset time period, then the power mode of the vehicle is controlled to be in the off mode.

[0075] Understandably, the above preset duration can be set according to the actual situation, such as 180 seconds.

[0076] For example, if the vehicle's power mode is not detected to switch to the on mode within 180 seconds after the current state of the hydrogen storage system switches from the hydrogen refueling state to the standby state, then the vehicle's power mode is controlled to be in the off mode.

[0077] Specifically, when the HMS detects that the hydrogen storage system's status has switched from refilling to standby, it sends this status to the BCM. The BCM starts a timer when it confirms that the hydrogen storage system's status has switched from refilling to standby. If the BCM does not receive a power-on request for the vehicle within 180 seconds, i.e., does not detect an operation to switch the vehicle's power mode to on, it sends a request to control the vehicle's power mode to off to the Powertrain Domain Control Unit (PDCU). The PDCU then controls the vehicle's power mode to off, thereby controlling the vehicle to shut down.

[0078] As mentioned earlier, during the hydrogen refueling process, the vehicle's power mode is in a non-power-on mode, namely the off mode (OFF mode), ACC mode, or CRANK mode.

[0079] Understandably, during the hydrogen refueling process, if the vehicle's power mode is in the off mode, and after the hydrogen storage system has switched from the refueling state to the standby state, if the vehicle's power mode is not detected to switch to the on mode within the aforementioned preset time period, then the vehicle's power mode will be kept in the off mode.

[0080] Similarly, during the hydrogen refueling process, if the vehicle's power mode is in ACC mode or CRANK mode, after determining that the hydrogen storage system has switched from the hydrogen refueling state to the standby state, if the vehicle's power mode is not detected to switch to the on mode within the aforementioned preset time period, the vehicle's power mode will be controlled to switch from ACC mode or CRANK mode to OFF mode.

[0081] To further ensure vehicle safety, the vehicle's current gear can be controlled while the vehicle is powered off.

[0082] In one possible implementation, controlling the power mode of the vehicle to be in the off mode includes: obtaining the current gear of the vehicle; if the current gear is not in the parking gear, controlling the current gear of the vehicle to switch to the parking gear, and controlling the power mode of the vehicle to be in the off mode.

[0083] Understandably, to prevent the vehicle from rolling away after power is cut off, the current gear position of the vehicle can be obtained. If the current gear position of the vehicle is not in the parking gear (P), the current gear position of the vehicle is switched to P, and then the power mode of the vehicle is switched off, that is, the vehicle is powered off.

[0084] Specifically, before controlling the vehicle's power mode to be in the off mode, the PDCU detects the vehicle's current gear and determines whether the current gear is in P gear. If it is determined that the current gear is not in P gear, the PDCU controls the vehicle to switch to P gear and then controls the vehicle to power off; if it is determined that the current gear is in P gear, the PDCU directly controls the vehicle to power off.

[0085] Furthermore, after the vehicle has been powered off, a reminder message can be sent to the terminal device bound to the vehicle to remind the user that the vehicle has been powered off.

[0086] For example, after the vehicle is powered off, it can send a reminder message to the mobile phone linked to the vehicle: "You did not operate the vehicle after refueling, and the vehicle has been automatically powered off."

[0087] In one possible scenario, if a request to switch the vehicle's power mode to the on mode is received within the aforementioned preset time period, the vehicle's power mode will be switched to the on mode to power on the vehicle.

[0088] Specifically, if the BCM receives a power-on request from the vehicle within the aforementioned preset time period, i.e., receives a signal to switch the vehicle's power mode to the on mode, it sends the signal to the PDCU. Upon receiving the signal, the PDCU controls the vehicle to power on.

[0089] The above method, after the hydrogen refueling operation is completed, promptly receives requests for vehicle power-on or power-off. If no power mode switching to on mode is detected within a preset time, the vehicle's power mode is controlled to be off, effectively reducing battery depletion. Furthermore, before controlling the vehicle's power mode to off, the vehicle's current gear is shifted to park to prevent the vehicle from rolling after power is off, further ensuring vehicle safety.

[0090] Figure 2 This is a schematic flowchart illustrating another method for controlling the locking of the hydrogenation port cover provided in an embodiment of this application.

[0091] For example, such as Figure 2 As shown, the method 200 includes:

[0092] S201, when the state of the hydrogen storage system is detected to have switched from hydrogen filling state to standby state, the state of the hydrogen filling port cover is obtained.

[0093] Understandably, after the vehicle is refueled with hydrogen, the HMS will control the hydrogen storage system to switch from the refueling state to the standby state. At the same time, the HMS will send the status of the hydrogen storage system to the Central Electronic Module (CEM) in the BCM. If the CEM detects that the hydrogen storage system has switched from the refueling state to the standby state, it can obtain the current status of the hydrogen refueling cap.

[0094] S202, determine whether the hydrogen filling port cap is closed.

[0095] Understandably, after receiving the current status of the hydrogen filling port cover, CEM can determine whether the hydrogen filling port cover is in a closed state.

[0096] For example, if the hydrogen filling port cap is closed, then S203 is executed; if the hydrogen filling port cap is not closed, then a reminder message is sent to the user to remind the user to close the hydrogen filling port cap.

[0097] S203, obtain the status of the four doors of the vehicle.

[0098] It is understandable that the above four door states refer to the states corresponding to the four doors of the vehicle, which are the door states described above.

[0099] S204, determine whether the four doors of the vehicle are locked.

[0100] For example, if the four doors of the vehicle are locked, then S207 is executed; if the four doors of the vehicle are not locked, then S205 is executed.

[0101] S205, obtain the status of the vehicle's powertrain system.

[0102] S206, determine whether the vehicle's power system is in a state of receiving a power-on request.

[0103] For example, if the power system is in a state of receiving a power-on request, then S207 is executed; if the power system is in a state of not receiving a power-on request, then the status of the four doors of the vehicle is obtained, that is, S203 is executed as described above.

[0104] S207, the electronic lock controlling the hydrogen filling port cover is in the locked state.

[0105] Understandably, if all four doors of the vehicle are locked, the electronic lock controlling the hydrogen refueling port cap will also be locked; if all four doors are not locked, but the vehicle's powertrain is in a state of receiving a power-on request, the electronic lock controlling the hydrogen refueling port cap will be locked.

[0106] The above method, upon detecting a transition of the hydrogen storage system from refueling to standby mode, acquires the status of the refueling cap. If the refueling cap is closed, it acquires the status of the vehicle's four doors. If the four doors are locked, it controls the electronic lock of the refueling cap to lock. If the four doors are not locked, it acquires the status of the vehicle's powertrain system. If the powertrain system has received a power-on request, it controls the electronic lock of the refueling cap to lock. This effectively prevents the refueling cap from accidentally opening after refueling, thus significantly reducing the risk of explosions due to hydrogen leakage, minimizing hazards, and enhancing vehicle safety.

[0107] Figure 3 This is a schematic diagram of a device for controlling the locking of a hydrogenation port cover according to an embodiment of this application.

[0110] The judgment module 302 is used to determine, based on the vehicle's status information, whether the preset conditions for controlling the electronic lock of the hydrogen refueling port cover to be in the locked state are met.

[0111] The control module 303 is used to control the electronic lock of the hydrogen filling port cover to be in a locked state when it is determined that the preset condition is met.

[0112] In one possible implementation, the vehicle's status information includes the status of the vehicle's doors and the status of the power system. The judgment module is specifically used to: when it is determined that the door is in an unlocked state, detect whether the power system has received a power-on request; if it is determined that the power system has received the power-on request, then determine that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are currently met.

[0113] In one possible implementation, the vehicle's status information includes the vehicle's door status. The judgment module is specifically used to: if it is determined that the door status is locked, then determine that the preset conditions for controlling the electronic lock of the hydrogen refueling port cover to be locked are met.

[0114] In one possible implementation, the vehicle's status information includes the status of the vehicle's doors and / or the status of the power system. The judgment module is specifically used to: if it is determined that the vehicle's doors are locked and / or the power system is in a state of receiving a power-on request, then determine that the preset conditions for controlling the electronic lock of the hydrogen refueling cap to be in a locked state are currently met.

[0115] Optionally, the device further includes a detection module, which is specifically used to: obtain the current status of the vehicle's hydrogen storage system; and detect whether the hydrogen refueling port cap is closed when the current status of the hydrogen storage system is detected to have switched from the hydrogen refueling state to the standby state.

[0117] Optionally, the device further includes a second control module, which is configured to: if no request to switch the power mode of the vehicle to the on mode is received within a preset time period, control the power mode of the vehicle to the off mode.

[0118] In one possible implementation, the second control module is specifically used to: obtain the current gear of the vehicle; if the current gear is not in the parking gear, control the current gear of the vehicle to switch to the parking gear, and control the power mode of the vehicle to be in the off mode.
