[0026] Figure 1 The present invention provides a flow chart of a method for controlling a hydrogen filling port cover, which can be applied to controlling a hydrogen filling port cover of a hydrogen fuel cell vehicle. The method can be executed by a hydrogen filling port cover control device, wherein the control device can be implemented by software and / or hardware, and the control device can be a body control module (BCM) and integrated into a hydrogen fuel cell vehicle. Figure 1 As shown, a hydrogen filling port cover control method provided by an embodiment of the present invention comprises the following steps:
[0027] S110: Obtain vehicle status information.
[0028] Among them, the vehicle status information includes the activation information of the hydrogen filling port unlocking switch, vehicle speed information, vehicle parking brake module working status information, charging gun connection information, hydrogen supply system working status information and high-voltage system working status information.
[0029] Exemplarily, the hydrogen filling port cover unlocking switch may be a button or a key structure, which is not limited in the embodiments of the present invention. When the user needs to refuel the vehicle with hydrogen, the hydrogen filling port cover unlocking switch may be pressed, and the hydrogen filling port cover unlocking switch responds to the opening action and sends the hydrogen filling port cover unlocking switch activation information to the hydrogen filling port cover control device. After receiving the hydrogen filling port cover unlocking switch activation information, the hydrogen filling port cover control device determines that the user has a hydrogen filling demand and executes the subsequent process.
[0030] The vehicle speed information refers to the current speed of the vehicle, which can be monitored by the electronic stability control system (ESC) and sent to the hydrogen filling port cover control device (for example, it can be BCM). The working status information of the vehicle parking brake module refers to the working status information of the electronic parking brake system (EPB), and the EPB sends its own working status information to the hydrogen filling port cover control device. The working status information of the vehicle parking brake module reflects whether the current vehicle is in the parking brake state. The charging gun connection information refers to the connection status information between the external charging gun and the charging port, which can be monitored by the on-board charger (OBC) and sent to the hydrogen filling port cover control device. The working status information of the hydrogen supply system refers to the working status information of the hydrogen management system (HMS), and the HMS sends its own working status information to the hydrogen filling port cover control device. The working status information of the hydrogen supply system can reflect whether the current HMS is in a hydrogen refueling ready state. The working status information of the high-voltage system refers to the current vehicle power supply status information, for example, it may include whether the current vehicle is in a high-voltage power state. The working status information of the high-voltage system can be collected and fed back by the vehicle controller (VCU). The above vehicle status information can be obtained by a vehicle status information acquisition module in the hydrogen filling port cover control device.
[0031] S120. Determine whether the vehicle meets the hydrogen filling port cover unlocking condition according to the vehicle status information.
[0032] Furthermore, the hydrogen filling port cover control device may include a hydrogen filling port cover unlocking condition judgment module, which judges whether the vehicle satisfies the hydrogen filling port cover unlocking condition according to the above-mentioned various vehicle status information.
[0033] S130, controlling the hydrogen filling port cover to unlock when the hydrogen filling port cover unlocking condition is met.
[0034] Furthermore, the hydrogen filling port cover control device may include a hydrogen filling port cover control module, which is used to adjust the state of the hydrogen filling port cover according to whether the vehicle meets the hydrogen filling port cover unlocking condition. For example, if the vehicle meets the hydrogen filling port cover unlocking condition, the hydrogen filling port cover is controlled to be unlocked, and if the hydrogen filling port cover unlocking condition is not met, the hydrogen filling port cover is controlled to be locked.
[0035] In the embodiment of the present invention, it is determined whether the unlocking condition of the hydrogen filling port cover is met according to a variety of vehicle status information, which can solve the problem of single unlocking judgment condition and incomplete coverage of the hydrogen filling port cover in the prior art, and ensure that hydrogen filling can be carried out only when the vehicle is safe enough, reducing the risk of explosion and other risks of the vehicle due to hydrogen leakage, reducing the possibility of harm, and greatly improving the safety of vehicle hydrogen filling. It solves the user's concerns about the safety of hydrogen filling when using hydrogen fuel cell vehicles, which is conducive to enhancing the safety of vehicle use and improving the user experience.
[0036] Exemplarily, the unlocking condition of the hydrogen filling port cover may include obtaining activation information of the hydrogen filling port cover unlocking switch, the vehicle speed is 0, the vehicle parking brake system is activated, the charging gun is in a disconnected state, the hydrogen supply system is ready for hydrogenation, and the vehicle is not in a high-voltage power state, but is not limited thereto. The acquisition of activation information of the hydrogen filling port cover unlocking switch indicates that the user has a hydrogen filling demand and has issued a hydrogen filling port cover unlocking instruction. It can then be determined whether the current vehicle speed is 0 and whether the vehicle parking brake system is activated. These two conditions indicate that the current vehicle is in a parking state. For safety reasons, vehicles are generally not allowed to refuel and charge at the same time. Therefore, when one of them cannot be in the execution process, the other energy replenishment should be disabled. In this embodiment, it is required to unlock the hydrogen filling port cover when the charging gun is in a disconnected state. The vehicle is not in a high-voltage power state, that is, the vehicle battery is in a high-voltage power-down state, and it is required to unlock the hydrogen filling port cover in the high-voltage power-down state. When the hydrogen filling port cover control device determines that the above-mentioned multiple hydrogen filling port cover unlocking conditions are met, the hydrogen filling port cover can be controlled to unlock.
[0037] A method for controlling a hydrogen filling port cover provided in an embodiment of the present invention first obtains vehicle status information, the vehicle status information including activation information of a hydrogen filling port cover unlocking switch, vehicle speed information, vehicle parking brake module working status information, charging gun connection information, hydrogen supply system working status information, and high-voltage system working status information; then, based on the vehicle status information, it is determined whether the vehicle meets the hydrogen filling port cover unlocking conditions, and the hydrogen filling port cover is controlled to unlock when the hydrogen filling port cover unlocking conditions are met. The above scheme can solve the problems of single hydrogen filling port cover unlocking judgment conditions and incomplete coverage scenarios in the prior art, ensure that hydrogen filling can be carried out only when the vehicle is safe enough, reduce the risk of explosion and the like due to hydrogen leakage, reduce the possibility of harm, and greatly improve the safety of vehicle hydrogen filling, which is conducive to enhancing the safety of vehicle use and improving user experience.
[0038] On the basis of the above embodiment, the present invention further proposes a variant embodiment of the above embodiment. It should be noted that, in order to make the description concise, only the differences from the above embodiment are described in the variant embodiment.
[0039] Optionally, in one embodiment, the hydrogen filling port cover unlocking condition includes a first unlocking condition and a second unlocking condition, the first unlocking condition includes that the vehicle speed is 0, the vehicle parking brake system is activated, and the charging gun is in a disconnected state, and the second unlocking condition includes that the hydrogen supply system is ready for hydrogenation and the vehicle is not in a high-voltage electrical state; (S120) in the above embodiment can be further refined as follows: after obtaining the activation information of the hydrogen filling port cover unlocking switch, determine whether the vehicle meets the first unlocking condition; start timing a preset time when the first unlocking condition is met, and determine whether the vehicle meets the second unlocking condition within the preset time; (S130) can be further refined as follows: within the preset time, if the second unlocking condition is met, control the hydrogen filling port cover to unlock.
[0040] Figure 2 A schematic flow chart of another hydrogenation port cover control method provided in an embodiment of the present invention, Figure 2 The control method shown is refined on the basis of the above embodiment, as shown in FIG. Figure 2 As shown, the hydrogen filling port cover control method comprises the following steps:
[0041] S210: Obtain vehicle status information.
[0042] Among them, the vehicle status information includes the activation information of the hydrogen filling port unlocking switch, vehicle speed information, vehicle parking brake module working status information, charging gun connection information, hydrogen supply system working status information and high-voltage system working status information.
[0043] S221. After obtaining the activation information of the hydrogen filling port unlocking switch, determine whether the vehicle meets the first unlocking condition.
[0044] The first unlocking condition can be understood as the basic condition that needs to be met to unlock the hydrogen filling port cover. After receiving the activation information of the hydrogen filling port cover unlocking switch, the hydrogen filling port cover unlocking condition judgment module first determines whether the vehicle speed is 0 according to the vehicle speed information fed back by the ESC, and determines whether the vehicle is in the parking brake state according to the vehicle parking brake module working status information fed back by the EPB, and determines whether the charging gun is in the disconnected state according to the charging gun connection information fed back by the OBC.
[0045] S222. When the first unlocking condition is met, start timing a preset time period, and determine whether the vehicle meets the second unlocking condition within the preset time period.
[0046] When the three first unlocking conditions, namely, the vehicle speed is 0, the vehicle parking brake system is activated, and the charging gun is in the disconnected state, are met, the hydrogen filling cover control device may send an unlocking request signal to the HMS and VCU. The HMS responds to the unlocking request signal to prepare for hydrogenation and feeds back the hydrogen supply system working status information to the hydrogen filling cover control device. The VCU responds to the unlocking request signal to perform a power-off operation and feeds back a power status signal to the hydrogen filling cover control device, which is the working status information of the high-voltage system. After the hydrogen filling cover control device sends the unlocking request signal, it starts timing a preset time. Within the preset time, the hydrogen filling cover control device determines whether the hydrogen supply system is ready for hydrogenation based on the hydrogen supply system working status information fed back by the HMS, and the hydrogen filling cover control device determines whether the vehicle is in a high-voltage electrical state based on the power status signal.
[0047] S230: If the second unlocking condition is met within a preset time period, the hydrogen filling port cover is controlled to be unlocked.
[0048] Furthermore, within the preset time, if the vehicle meets the hydrogen supply system hydrogenation readiness and the vehicle is not in a high voltage state, it can be determined that the vehicle is ready for hydrogenation, and then it can be determined that the hydrogenation cover unlocking condition is met. The hydrogenation cover control device drives the hydrogenation cover lock to complete the unlocking action, and at the same time sends an unlocking success signal to the HMS and VCU, etc., to realize the closed loop of each control module in the vehicle.
[0049] It should be noted that the executor of the hydrogen filling cap control method provided in the embodiment of the present invention is a hydrogen filling cap control device (for example, a BCM). However, during the execution of the control method, interactions between different control modules in the vehicle are involved, such as interactions between BCM and ESC, EPB, OBC, HMS and VCU, and interactions between HMS and VCU.
[0050] In this embodiment, it is first determined whether the first unlocking condition is met. Within a preset time after the first unlocking condition is met, it is determined whether the hydrogen filling port cover unlocking condition is met based on whether the hydrogen filling preparation is completed, which can further ensure the safety of unlocking the hydrogen filling port cover.
[0051] Optionally, in a possible embodiment, the above (S230) may be further refined as follows: within a preset time period, if the vehicle satisfies both the first unlocking condition and the second unlocking condition, the hydrogen filling port cover is controlled to be unlocked.
[0052] In this embodiment, after the timing starts, it is still necessary to determine whether the vehicle meets the conditions that the vehicle speed is 0, the vehicle parking brake system is activated, and the charging gun is in a disconnected state. If the vehicle speed is 0, the vehicle parking brake system is activated, the charging gun is in a disconnected state, the hydrogen supply system is ready for hydrogenation, and the vehicle is not in a high voltage state, it is determined that hydrogenation is ready, and then the hydrogenation cover is controlled to be unlocked.
[0053] In this way, it is possible to continuously detect whether the vehicle meets the first unlocking condition, thereby preventing the user from performing operations such as shifting gears and releasing the EPB during the preparation period for unlocking the hydrogen filling port cover, thereby ensuring unlocking safety.
[0054] Optionally, in a possible embodiment, the hydrogen filling port cover control method further includes: when the vehicle does not meet any one of the first unlocking condition and the second unlocking condition, controlling the hydrogen filling port cover to be locked.
[0055] Specifically, after (S221), it may include: when the first unlocking condition is not met, the hydrogen filling cover control device determines that the hydrogen filling cover is not allowed to be unlocked, and controls the hydrogen filling cover to maintain a locked state. After (S222), it may also include: within a preset time period, if the second unlocking condition is not met, the hydrogen filling cover control device determines that the hydrogen filling cover has failed to be unlocked, and controls the hydrogen filling cover to maintain a locked state. At the same time, the hydrogen filling cover control device may also send an unlocking failure signal to control modules such as HMS and VCU, and control modules such as HMS and VCU respond to the unlocking failure signal to restore the initial state.
[0056] Optionally, in a possible embodiment, (S222) in the above embodiment (determining whether the vehicle meets the second unlocking condition within a preset time) can be refined as follows: within the preset time, if the hydrogen supply system is ready for hydrogen refueling and the hydrogen purge end signal is received, it is determined that the second unlocking condition is met; if the hydrogen supply system is ready for hydrogen refueling or the hydrogen purge end signal is not received, it is determined that the second unlocking condition is not met; the hydrogen purge end signal includes a purge action not executed signal or a purge action completion signal.
[0057] Specifically, in step (S222), after the first unlocking condition is met, the hydrogen filling port control device can simultaneously send an unlocking request signal to the HMS, VCU and fuel cell controller (FCCU). The HMS responds to the unlocking request signal to enter the hydrogenation preparation state and sends a hydrogen supply system hydrogenation readiness signal to the hydrogen filling port control device and VCU. The FCCU responds to the unlocking request signal to perform a hydrogen purge action and sends a hydrogen purge end signal to the VCU and the hydrogen filling port control device.
[0058] The VCU responds to the unlocking request signal and prepares to enter the power-off stage. Within the preset time, when the VCU receives the hydrogen supply system hydrogenation readiness signal issued by the HMS and the hydrogen purge end signal issued by the FCCU, the VCU performs the power-off operation, and after completing the power-off operation, it feeds back the power status signal = ig off to the hydrogen filling port control device, and the hydrogen filling port control device determines that the vehicle is not in a high-voltage power state based on this.
[0059] Hydrogen purging before unlocking the hydrogen filling port cover can ensure the dryness of the inside of the hydrogen filling gun and the connection of the hydrogen filling port, and prevent problems caused by moisture or ice. During the power-off process, if the FCCU does not perform the hydrogen purging action or the purging action is completed within the preset time, it means that the current hydrogen concentration at the hydrogen filling port meets the requirements for opening the cover, and the hydrogen filling port cover control device can control the completion of the hydrogen filling port cover unlocking action; if the purging action is not completed within the preset time, it means that the hydrogen concentration at the hydrogen filling port does not meet the requirements for opening the cover. At this time, the hydrogen filling port cover control device can determine that the hydrogen filling port cover has failed to be unlocked, and send an unlocking failure signal to the control modules such as HMS and VCU. The control modules such as HMS and VCU respond to the unlocking failure signal to restore the initial state.
[0060] Optionally, the value of the preset duration is not limited, and those skilled in the art may set it according to actual needs. For example, in a possible embodiment, the preset duration may be 200 to 400 seconds, for example, 300 seconds, but is not limited thereto.
[0061] Optionally, the vehicle further includes an interaction module, the hydrogen filling port cover control device may be electrically connected to the interaction module, and the interaction module may be a center console of the vehicle. In a possible embodiment, after (S120) in the above embodiment, it may also include: controlling the hydrogen filling port cover to be locked when the hydrogen filling port cover unlocking condition is not met and determining the reason for unlocking failure; the reason for unlocking failure includes at least one of the vehicle speed is not 0, the vehicle parking brake system is not activated, the charging gun is in a connected state, the hydrogen supply system is not ready for hydrogen filling, and the vehicle is in a high voltage state; using the interaction module to display the unlocking failure information, the unlocking failure information includes the unlocking failure reason.
[0062] As described in the above embodiments, the unlocking conditions of the hydrogen filling port cover may include the vehicle speed being 0, the vehicle parking brake system being activated, the charging gun being disconnected, the hydrogen supply system being ready for hydrogen filling, and the vehicle not being in a high voltage state. When the vehicle does not meet any of the above unlocking conditions, the hydrogen filling port cover is controlled to remain in a locked state. The specific reasons for the unlocking failure are displayed through a pop-up window on the instrument panel of the center console so that the user knows the reasons for the unlocking failure.
[0063] Exemplarily, in step (S221) of the above embodiment, if it is determined that one of the first unlocking conditions is not met, the hydrogen filling cover control device controls the hydrogen filling cover to be locked, and sends the information of the unmet first unlocking condition to the interactive module, which is displayed by the interactive module. For example, if it is determined that the charging gun is in a connected state, it is prompted that "the hydrogen filling cover failed to be unlocked, and the reason for failure is: the charging gun is in a connected state". In step (S222), if it is determined that one of the second unlocking conditions is not met, the hydrogen filling cover control device controls the hydrogen filling cover to be locked, and sends the information of the unmet second unlocking condition to the interactive module, which is displayed by the interactive module. For example, if it is determined that the hydrogen supply system is not ready for hydrogenation, it is prompted that "the hydrogen filling cover failed to be unlocked, and the reason for failure is: the hydrogen supply system is not ready for hydrogenation".
[0064] In this way, the user can intuitively see the reason why the hydrogen filling cap fails to be unlocked, so that the user can adjust the vehicle status in time.
[0065] Correspondingly, after (S130), the method may further include: displaying unlocking success information or unlocking in progress information by using an interactive module.
[0066] After determining that the conditions for unlocking the hydrogen filling port cover are met, the interactive module can be used to prompt the unlocking process. For example, during the process of controlling the unlocking of the hydrogen filling port cover, a pop-up window on the instrument panel on the center console can prompt "Unlocking, please wait" and other words; after the hydrogen filling port cover is unlocked, a pop-up window on the instrument panel on the center console can prompt "Unlocking successful" and other words, so that the user can understand the unlocking progress.
[0067] Based on the same concept, an embodiment of the present invention further provides a hydrogen filling port cover control device, which is used to execute the hydrogen filling port cover control method provided by any embodiment of the present invention. The hydrogen filling port cover control device can be implemented by software and / or hardware, and the control device can be a BCM integrated in a hydrogen fuel cell vehicle. Figure 3 A schematic diagram of a hydrogen filling port cover control device provided in an embodiment of the present invention, referring to Figure 3 , the hydrogen filling port cover control device includes:
[0068] The vehicle status acquisition information module 100 is used to acquire vehicle status information, including activation information of the hydrogen filling port unlocking switch, vehicle speed information, vehicle parking brake module working status information, charging gun connection information, hydrogen supply system working status information, and high-voltage system working status information;
[0069] A hydrogen filling port cover unlocking condition judgment module 200 is used to judge whether the vehicle meets the hydrogen filling port cover unlocking condition according to the vehicle state information;
[0070] The hydrogen filling port cover control module 300 is used to control the hydrogen filling port cover to be unlocked when the hydrogen filling port cover unlocking condition is met.
[0071] The hydrogenation port cover control device provided in the embodiment of the present invention includes all the technical features of the hydrogenation port cover control method provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of the execution method, which will not be described in detail here.
[0072] When executing the hydrogen filling lid control method, the hydrogen filling lid control device provided in the embodiment of the present invention will interact with different control modules in the vehicle, such as the interaction between the hydrogen filling lid control device (hereinafter referred to as "BCM") and the ESC, EPB, OBC, HMS and VCU. In an exemplary embodiment, Figure 4 An interactive schematic diagram of a hydrogen filling port cover control device provided by an embodiment of the present invention, such as Figure 4 As shown, when the user presses the hydrogen filling cover lock switch, the hydrogen filling cover lock switch sends the hydrogen filling cover unlock switch activation information to the BCM, the ESC sends the vehicle speed information to the BCM, the EPB sends the vehicle parking brake module working status information to the BCM, and the OBC sends the charging gun connection information to the BCM. If the BCM determines that the vehicle speed is not 0 or the vehicle parking brake system is not activated or the charging gun is in a connected state, it determines that the unlocking fails, maintains the hydrogen filling cover locked, and sends the unlocking failure information to the interactive module HMI. If the BCM determines that the vehicle speed is 0, the vehicle parking brake system is activated, and the charging gun is in a disconnected state, it sends an unlocking request signal to the VCU and HMS and starts timing the preset duration. After receiving the unlocking request signal, the HMS completes the hydrogenation preparation action and then feeds back the hydrogen supply system hydrogenation readiness signal to the BCM and VCU; the FCCU performs hydrogen purge work, and after the hydrogen purge is completed, the FCCU sends a hydrogen purge end signal to the VCU and BCM. The VCU responds to the hydrogen purge end signal and starts to power off, and after the power off is completed, it sends a power status signal = ig off to the BCM. Within the preset time of sending the unlock request, if the BCM receives the hydrogen supply system hydrogenation ready signal and the power status signal = ig off, it can control the hydrogenation cover to unlock and send the unlock success information to the interactive module. Within the preset time of sending the unlock request, if the BCM does not receive any of the hydrogenation ready signal and the power status signal = ig off, it is judged that the unlocking fails, the hydrogenation cover is kept locked, and the unlocking failure information is sent to the HMI.
[0073] An embodiment of the present invention further provides a vehicle, comprising a memory for storing executable program code; and a processor for calling and running the executable program code from the memory, so that the vehicle executes the hydrogen filling port cover control method in any embodiment of the present invention.
[0074] The vehicle may include a hydrogen filler flap control device (eg, a BCM), an ESC, an EPB, an OBC, and a HMS, but is not limited thereto.
[0075] An embodiment of the present invention further provides a computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, the hydrogenation port cover control method provided by any embodiment of the present invention is implemented.
