Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a method for determining information for hydrogen fuel cell vehicles, the vehicle itself, and a storage medium. Background Technology

[0002] Hydrogen fuel cell vehicles are becoming increasingly popular as a new energy vehicle in daily use. The amount of hydrogen consumed per unit distance (e.g., hydrogen consumption per 100 kilometers) is a crucial performance indicator. Currently, the amount of hydrogen consumed per unit distance is generally calculated by periodically measuring the vehicle's mileage and hydrogen consumption. However, this method is susceptible to the effects of vehicle idling, leading to significant errors in the calculated hydrogen consumption per unit distance. This results in substantial deviations in performance parameters such as driving range based on the calculated hydrogen consumption per unit distance, making it impossible to accurately evaluate the vehicle's actual performance. Summary of the Invention

[0003] The main objective of this invention is to provide a method for determining information about hydrogen fuel cell vehicles, as well as the vehicle and its storage medium, aiming to improve the accuracy of the obtained hydrogen consumption per unit mileage and the accuracy of vehicle performance evaluation.

[0004] To achieve the above objectives, the present invention provides a method for determining information about a hydrogen fuel cell vehicle, the method comprising the following steps:

[0005] Obtain the hydrogen consumption and driving range of the vehicle equipped with the hydrogen fuel cell system from the first moment at the start to the current second moment;

[0006] When the driving mileage is greater than or equal to the preset mileage, the first unit mileage hydrogen consumption is determined based on the driving mileage and the hydrogen consumption.

[0007] The target hydrogen consumption per unit mileage of the vehicle is determined based on the first unit mileage hydrogen consumption and the second unit mileage hydrogen consumption.

[0008] Wherein, the second unit mile hydrogen consumption is a parameter determined based on a preset unit mile hydrogen consumption, which is a parameter obtained by pre-testing under preset operating conditions.

[0009] Optionally, the step of determining the target hydrogen consumption per unit mileage of the vehicle based on the first unit mileage hydrogen consumption and the second unit mileage hydrogen consumption includes:

[0010] The target hydrogen consumption per unit mileage is determined based on the average of the first unit mileage hydrogen consumption and the second unit mileage hydrogen consumption.

[0011] Optionally, the second time point is a time point during the vehicle's operation after it is powered on. Following the step of determining the target hydrogen consumption per unit mile based on the first unit mile hydrogen consumption and the second unit mile hydrogen consumption, the method further includes:

[0012] When no power-down command is received, the second time is set to the new first time, the target unit mileage hydrogen consumption is set to the new second unit mileage hydrogen consumption, and the process returns to the step of obtaining the hydrogen consumption and driving mileage of the vehicle where the hydrogen fuel cell system is located from the initial first time to the current second time.

[0013] When the power-off command is received, the target hydrogen consumption per unit mileage is stored. When the vehicle is powered on again after being powered off, the stored target hydrogen consumption per unit mileage is set as the new second hydrogen consumption per unit mileage. The time when the vehicle is powered on again is set as the new first time. Then, the process returns to the step of obtaining the hydrogen consumption and driving mileage of the vehicle with the hydrogen fuel cell system from the initial first time to the current second time.

[0014] Optionally, after the step of determining the first unit mileage hydrogen consumption based on the mileage and the hydrogen consumption when the mileage is greater than or equal to a preset mileage, the method further includes:

[0015] When the first time is the target type time, the preset unit mileage hydrogen consumption is determined to be the second unit mileage hydrogen consumption; the target type time includes the time when the vehicle is first powered on after leaving the factory or the time when the vehicle receives the preset initialization command.

[0016] Optionally, the method for determining the information of the hydrogen fuel cell vehicle further includes the following steps:

[0017] When the vehicle operation meets the preset conditions, the preset hydrogen consumption per unit mileage is determined as the target hydrogen consumption per unit mileage.

[0018] When the vehicle operation does not meet the preset conditions, the step of obtaining the hydrogen consumption and driving range of the vehicle containing the hydrogen fuel cell system from the first moment at the beginning to the current second moment is executed.

[0019] The preset conditions include receiving a preset initialization command or the vehicle being powered on for the first time after leaving the factory.

[0020] Optionally, the step of obtaining the hydrogen consumption and driving range of the vehicle equipped with the hydrogen fuel cell system from the initial first moment to the current second moment includes:

[0021] The remaining hydrogen quantity of the hydrogen fuel cell system corresponding to the first time point and the second time point are obtained respectively, wherein the remaining hydrogen quantity corresponding to the first time point is the first remaining hydrogen quantity, and the remaining hydrogen quantity corresponding to the second time point is the second remaining hydrogen quantity.

[0022] The hydrogen consumption is determined based on the difference between the first remaining hydrogen quantity and the second remaining hydrogen quantity.

[0023] Optionally, the second time and the first time are defined as target times, and before the step of obtaining the remaining hydrogen quantity of the hydrogen fuel cell system corresponding to the second time and the first time respectively, the method further includes:

[0024] Continuously monitor the internal state parameters of the hydrogen fuel cell system;

[0025] The reference value of the remaining hydrogen in the hydrogen fuel cell system is determined based on the internal state parameters, and the difference between the reference value and the initial value is determined; the initial value is the remaining hydrogen in the hydrogen fuel cell system determined based on the internal state parameters at the time the vehicle is powered on.

[0026] When the difference satisfies the first condition or the second condition, the reference value corresponding to the target time is determined to be the amount of remaining hydrogen at the target time.

[0027] When the difference does not meet the first condition and the second condition, the initial value is determined to be the amount of remaining hydrogen corresponding to the target time.

[0028] The first condition includes the difference corresponding to the target time being less than or equal to a first preset threshold, and the difference being continuously less than or equal to the first preset threshold within a first preset duration before the target time. The second condition includes the difference corresponding to the target time being greater than or equal to the second preset threshold, and the difference being continuously greater than or equal to the second preset threshold within a second preset duration before the target time. The first preset threshold is less than the second preset threshold.

[0029] Optionally, after obtaining the amount of the second remaining hydrogen at the second time point, the method further includes:

[0030] Output the first prompt message corresponding to the second remaining hydrogen amount.

[0031] Optionally, after determining the target hydrogen consumption per unit mile of the vehicle based on the first unit mile hydrogen consumption and the second unit mile hydrogen consumption, the method further includes:

[0032] The available hydrogen quantity of the hydrogen fuel cell system is determined based on the deviation between the remaining hydrogen quantity of the hydrogen fuel cell system at the second moment and the preset hydrogen quantity.

[0033] The vehicle's range is determined based on the available hydrogen supply and the target hydrogen consumption per unit mileage.

[0034] Output the second prompt message corresponding to the stated driving range.

[0035] The preset hydrogen quantity is the minimum amount of hydrogen required for the normal operation of the hydrogen fuel cell system.

[0036] Optionally, after determining the target hydrogen consumption per unit mile of the vehicle based on the first unit mile hydrogen consumption and the second unit mile hydrogen consumption, the method further includes:

[0037] Get the remaining mileage when the user sets the hydrogen refueling prompt;

[0038] The hydrogen quantity threshold for the vehicle refueling prompt is determined based on the remaining mileage and the target hydrogen consumption per unit mileage.

[0039] When the remaining hydrogen amount in the hydrogen fuel cell system at the second time is less than or equal to the hydrogen amount threshold, a hydrogen refueling prompt message is output.

[0040] And / or, output the third prompt information corresponding to the target unit mileage hydrogen consumption.

[0041] Furthermore, in order to achieve the above objectives, this application also proposes a vehicle comprising:

[0042] Hydrogen fuel cell systems; and

[0043] An information determination device, comprising: a memory, a processor, and an information determination program for a hydrogen fuel cell vehicle stored in the memory and executable on the processor, wherein the information determination program for the hydrogen fuel cell vehicle, when executed by the processor, implements the steps of the information determination method for the hydrogen fuel cell vehicle as described in any of the preceding claims.

[0044] In addition, to achieve the above objectives, this application also proposes a storage medium storing a hydrogen fuel cell vehicle information determination program, which, when executed by a processor, implements the steps of the hydrogen fuel cell vehicle information determination method as described in any of the preceding claims.

[0045] This invention proposes a method for determining information about hydrogen fuel cell vehicles. When the vehicle's mileage from the start time reaches a preset mileage, the method calculates the first unit mileage hydrogen consumption within that time period based on the mileage and the corresponding hydrogen consumption. This first unit mileage hydrogen consumption is then combined with a second unit mileage hydrogen consumption determined by pre-testing under preset operating conditions to determine the vehicle's target unit mileage hydrogen consumption. This method effectively avoids excessively high unit mileage hydrogen consumption due to insufficient mileage caused by vehicle idling within a fixed time period. Furthermore, combining the actual unit mileage hydrogen consumption during vehicle operation with the preset unit mileage hydrogen consumption obtained from standard testing to determine the target unit mileage hydrogen consumption further avoids the influence of actual mileage errors on the unit mileage hydrogen consumption. Therefore, this method effectively improves the accuracy of the obtained unit mileage hydrogen consumption, ensuring accurate evaluation of vehicle range and other performance characteristics based on the obtained target unit mileage hydrogen consumption, thus improving the accuracy of vehicle performance evaluation.

[0052] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0053] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0054] This invention provides a vehicle, specifically a hydrogen fuel cell vehicle, which uses a hydrogen fuel cell system as its onboard power source.

[0055] In this embodiment of the invention, reference is made to Figure 1 The vehicle includes a hydrogen fuel cell system 1, an odometer 3, a detection module 4, a notification device 5, and an information determination device 2. The odometer 3, the detection module 4, and the notification device 5 are all connected to the information determination device 2. The information determination device 2 can be used to acquire data detected by the odometer 3 and the detection module 4, and can also be used to control the notification device 5 to output and display information.

[0056] The prompting device 5 may include a display module, a voice module, and / or a lighting module, etc. In this embodiment, the prompting device 5 is the vehicle's instrument panel.

[0057] In this embodiment, the information determination device 2 includes a first module built into the vehicle controller, a second module built into the hydrogen storage system controller, and a third module built into the instrument panel controller. The third module is connected to the instrument panel. The second module is used to calculate the remaining hydrogen quantity of the hydrogen fuel cell system 1. The third module is used to acquire the hydrogen consumption per unit mileage, driving range, hydrogen refueling reminder information, and remaining available hydrogen mass output by the first module and output them to the instrument panel display. The third module can also be used to acquire the remaining mileage when the user inputs a hydrogen refueling reminder based on the instrument panel and send it to the first module. The first module is used to determine the hydrogen consumption per unit mileage, driving range, hydrogen refueling reminder information, and / or remaining available hydrogen mass based on the information input by the second module and / or the third module. In other embodiments, the information determination device 2 may also be an integrated device of the first, second, and third modules.

[0058] The odometer 3 is used to calculate the vehicle's mileage. The detection module 4 is located within the hydrogen fuel cell system 1 and is used to detect the internal state parameters of the hydrogen fuel cell system 1.

[0059] In this embodiment of the invention, reference is made to Figure 1 The information determination device 2 includes a processor 1001 (e.g., CPU), a memory 1002, a timer 1003, etc. The components in the control device are connected via a communication bus. The memory 1002 can be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0060] Those skilled in the art will understand that Figure 1The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0061] like Figure 1 As shown, the memory 1002, which serves as a storage medium, may include an information determination program for hydrogen fuel cell vehicles. Figure 1 In the device shown, the processor 1001 can be used to call the hydrogen fuel cell vehicle information determination program stored in the memory 1002 and execute the relevant steps of the hydrogen fuel cell vehicle information determination method in the following embodiments.

[0062] This invention also provides a method for determining information about a hydrogen fuel cell vehicle, applicable to the aforementioned vehicle.

[0063] Reference Figure 2 This application proposes an embodiment of a method for determining information about a hydrogen fuel cell vehicle. In this embodiment, the method for determining information about a hydrogen fuel cell vehicle includes:

[0064] Step S10: Obtain the hydrogen consumption and driving range of the vehicle with the hydrogen fuel cell system from the first moment at the start to the current second moment;

[0065] The first moment can be the moment the vehicle is powered on, the moment the vehicle reaches preset conditions after being powered on, or the moment when a preset command is received from the user.

[0066] Hydrogen consumption specifically refers to the amount of hydrogen consumed by the vehicle between the first and second moments. Specifically, in this embodiment, a power-on cycle is defined as the continuous operation of the vehicle from the moment of power-on to the moment of power-off. The first and second moments belong to the same power-on cycle and can be determined based on the deviation between the amount of hydrogen remaining in the hydrogen fuel cell system detected at the first moment and the amount of hydrogen remaining in the hydrogen fuel cell system detected at the second moment. Alternatively, an intermediate moment of vehicle power-on can be determined between the first and second moments, and the hydrogen consumption can be determined based on the amount of hydrogen remaining in the hydrogen fuel cell system corresponding to the first moment, the intermediate moment, and the second moment, respectively.

[0067] The mileage is determined based on the difference between the second mileage detected by the odometer at the second moment and the first mileage detected by the odometer at the first moment.

[0068] Step S20: When the driving mileage is greater than or equal to the preset mileage, determine the first unit mileage hydrogen consumption based on the driving mileage and the hydrogen consumption.

[0069] The preset mileage is a pre-calibrated value, ranging from 5km to 10km.

[0070] The first unit mile hydrogen consumption specifically represents the average amount of hydrogen consumed by the hydrogen fuel cell system when the vehicle travels a unit mile between the first and second time points.

[0071] In this embodiment, the unit mileage corresponding to the first unit mileage hydrogen consumption, the subsequent second unit mileage hydrogen consumption, and the target unit mileage hydrogen consumption is all the same and is 100 kilometers, thus representing the hydrogen consumption per 100 kilometers. In other embodiments, the unit mileage corresponding to the first unit mileage hydrogen consumption, the subsequent second unit mileage hydrogen consumption, and the target unit mileage hydrogen consumption can also be other numerical unit mileage values, such as 1000 kilometers, 10 kilometers, 1 kilometer, etc., and the first unit mileage hydrogen consumption, the subsequent second unit mileage hydrogen consumption, and the target unit mileage hydrogen consumption can each correspond to a different unit mileage.

[0072] When the driving mileage is greater than or equal to the preset mileage, the first unit mileage hydrogen consumption can be determined based on the ratio of hydrogen consumption to driving mileage and the unit mileage corresponding to the first unit mileage hydrogen consumption. For example, if the hydrogen consumption is Δm, the driving mileage is Δd, and the unit mileage is 100 kilometers, then the average hydrogen consumption per 100 kilometers can be calculated by Δm / Δd*100 and used as the first unit mileage hydrogen consumption.

[0073] If the driving mileage is less than the preset mileage, return to step S10. Based on this, it can be ensured that the hydrogen consumption per unit mileage is calculated only when the driving mileage reaches the preset mileage.

[0074] Step S30: Determine the target hydrogen consumption per unit mileage of the vehicle based on the first hydrogen consumption per unit mileage and the second hydrogen consumption per unit mileage; wherein, the second hydrogen consumption per unit mileage is a parameter determined based on a preset hydrogen consumption per unit mileage, and the preset hydrogen consumption per unit mileage is a parameter obtained by pre-testing under preset operating conditions.

[0075] The second unit mile hydrogen consumption can be a preset unit mile hydrogen consumption, or it can be a value determined before the current time by combining the preset mile hydrogen consumption and other parameters according to preset rules.

[0076] The target hydrogen consumption per unit mileage is the actual amount of hydrogen consumed by the hydrogen fuel cell system when the vehicle travels a unit mile.

[0077] The preset operating conditions can be test conditions defined according to industry standards, national standards, or regional standards, or test conditions customized by the vehicle manufacturer. The hydrogen consumption per unit mile of the vehicle is tested under these preset operating conditions and the results are stored to form the preset hydrogen consumption per unit mile. After the vehicle leaves the factory, the preset hydrogen consumption per unit mile is a pre-stored fixed parameter that will not change with the vehicle's actual driving conditions.

[0078] In one implementation of this embodiment, the target hydrogen consumption per unit mile is determined based on the average of the first hydrogen consumption per unit mile and the second hydrogen consumption per unit mile. For example, if the first hydrogen consumption per unit mile is F1 and the second hydrogen consumption per unit mile is F2, then the target hydrogen consumption per unit mile = (F1 + F2) / 2.

[0079] In another implementation of this embodiment, the first weight and the second weight corresponding to the first unit mileage hydrogen consumption and the second unit mileage hydrogen consumption can be obtained, respectively. The target unit mileage hydrogen consumption can then be obtained by weighted averaging the first unit mileage hydrogen consumption and the second unit mileage hydrogen consumption according to the first weight and the second weight. The first weight and the second weight can be preset fixed values, or they can be determined based on the total mileage traveled by the vehicle after leaving the factory or after receiving the initialization command. Different total mileages will result in different first weights and second weights.

[0080] Furthermore, after step S30, a third prompt message corresponding to the target hydrogen consumption per unit mileage can be output. This third prompt message may include display, voice, or light prompts. In this embodiment, the target hydrogen consumption per unit mileage is displayed on the vehicle's instrument panel.

[0081] This invention proposes a method for determining information about a hydrogen fuel cell vehicle. When the vehicle's mileage from the start time reaches a preset mileage, the method calculates the first unit mileage hydrogen consumption within that time period based on the mileage and the corresponding hydrogen consumption. This first unit mileage hydrogen consumption is then combined with a second unit mileage hydrogen consumption determined by a preset unit mileage hydrogen consumption obtained from pre-tests under preset operating conditions to determine the vehicle's target unit mileage hydrogen consumption. This method effectively avoids excessively high unit mileage hydrogen consumption due to insufficient mileage caused by vehicle idling within a fixed time period. Furthermore, combining the actual unit mileage hydrogen consumption during vehicle operation with the preset unit mileage hydrogen consumption obtained from standard tests to determine the target unit mileage hydrogen consumption further avoids the influence of actual mileage errors on the unit mileage hydrogen consumption. Therefore, this method effectively improves the accuracy of the obtained vehicle unit mileage hydrogen consumption, ensuring accurate evaluation of vehicle performance based on the obtained target unit mileage hydrogen consumption and improving the accuracy of vehicle performance evaluation.

[0082] Furthermore, based on the above embodiments, another embodiment of the method for determining information of hydrogen fuel cell vehicles according to this application is proposed. In this embodiment, reference is made to... Figure 3 The second time point is the time point during the operation of the vehicle after it is powered on. After step S30, the method further includes:

[0083] Step S40: When no power-down command is received, the second time is set to the new first time, and the target hydrogen consumption per unit mileage is set to the new second hydrogen consumption per unit mileage; after step S40, return to the step of obtaining the hydrogen consumption and driving mileage of the vehicle where the hydrogen fuel cell system is located from the initial first time to the current second time.

[0084] In step S50, when a power-down command is received, the target hydrogen consumption per unit mileage is stored, and when the vehicle is powered on again after being powered down, the stored target hydrogen consumption per unit mileage is set as the new second hydrogen consumption per unit mileage, and the time when the vehicle is powered on again is set as the new first time. After step S50, the process returns to the step of obtaining the hydrogen consumption and driving mileage of the vehicle where the hydrogen fuel cell system is located from the initial first time to the current second time.

[0085] In this embodiment, the driving mileage that was not included in the calculation of hydrogen consumption per unit mileage when the power-down command is received will not be included in the subsequent calculation of hydrogen consumption per unit mileage when the vehicle is powered on again after being powered off.

[0086] To better understand the solution in this embodiment, a specific example will be used for illustration below:

[0087] Define the first moment as T1, and the current moment Tn (n≥2, n is an integer) during the vehicle's operation after power-on. The time interval between Tn and T1 is (n-1) times the set time interval t. If the vehicle's mileage Δd1 between T1 and the second moment T2 is greater than or equal to the preset mileage, then the first unit mileage hydrogen consumption F1 can be calculated based on Δd1 and the hydrogen consumption Δm1 between T1 and T2. At this time, the vehicle's second unit mileage hydrogen consumption is F0. Then, the average of F1 and F0 can be determined as the target unit mileage hydrogen consumption Fn1.

[0088] If no power-down command is received after obtaining Fn1, T2 is taken as the new first time point, and Fn1 is taken as the new second unit mileage hydrogen consumption. If the vehicle's mileage Δd2 between T2 and the third time point after T2 (i.e., the new second time point) T3 is less than the preset mileage, the target unit mileage hydrogen consumption is not calculated. If the vehicle's mileage Δd3 between T2 and the fourth time point after T2 (i.e., the new second time point) T4 is greater than or equal to the preset mileage, the first unit mileage hydrogen consumption F2 can be calculated based on Δd3 and the hydrogen consumption Δm2 between T2 and T4. At this time, the vehicle's second unit mileage hydrogen consumption is Fn1, and the average of Fn1 and F2 can be determined as the target unit mileage hydrogen consumption Fn2. If no power-down command is received after obtaining Fn2, the above loop continues. If a power-down command is received after obtaining Fn2, the process after obtaining Fn1 and receiving the power-down command is executed as described below.

[0089] Upon obtaining Fn1 and receiving a power-down command, the current target hydrogen consumption per unit mileage, Fn1, is stored. When the vehicle is powered on again after a power-down, the stored Fn1 is read as the new second hydrogen consumption per unit mileage. The time Tk at which the vehicle is powered on again is taken as the new first time. If the vehicle's mileage Δdk between Tk and Tkn (which follows Tk) is greater than or equal to a preset mileage, the first hydrogen consumption per unit mileage, F3, can be calculated based on Δdk and the hydrogen consumption Δmk between Tk and Tkn. At this point, the vehicle's second hydrogen consumption per unit mileage is Fn1, thus the average of Fn1 and F3 is determined to be the target hydrogen consumption per unit mileage, Fn3. If no power-down command is received after obtaining Fn3, the process described above (after obtaining Fn1 but not receiving a power-down command) is executed cyclically. If a power-down command is received after obtaining Fn3, the process described here (after obtaining Fn1 and receiving a power-down command) is executed cyclically.

[0090] In this embodiment, through steps S40 and S50, the target hydrogen consumption per unit mileage during vehicle operation after power-on can be continuously updated iteratively based on actual driving conditions. Changes in vehicle usage after power-off (e.g., changes in the amount of hydrogen stored before and after power-off due to refueling the hydrogen fuel cell system, or no travel during the power-off period) do not affect the calculation of the target hydrogen consumption per unit mileage, thus improving the accuracy of the target hydrogen consumption per unit mileage and the accuracy of vehicle performance evaluation. Furthermore, calculating the target hydrogen consumption per unit mileage every time a preset mileage is reached helps ensure the accuracy and timeliness of the target hydrogen consumption per unit mileage determination, improving the accuracy and timeliness of information based on the determination or output of the target hydrogen consumption per unit mileage.

[0091] Furthermore, in this embodiment, before the step of determining the target hydrogen consumption per unit mileage of the vehicle based on the first unit mileage hydrogen consumption and the second unit mileage hydrogen consumption, the method further includes:

[0092] When the first time is the target type time, the preset unit mileage hydrogen consumption is determined to be the second unit mileage hydrogen consumption; the target type time includes the time when the vehicle is first powered on after leaving the factory or the time when the vehicle receives the preset initialization command.

[0093] The preset initialization command is used to initialize the vehicle's current target hydrogen consumption per unit mile. In this embodiment, the preset initialization command is input by the user through a button on the instrument panel (which can be a physical button or a virtual button). In other embodiments, the preset initialization command can also be input by the user through a mobile terminal connected to the vehicle.

[0094] In this embodiment, when the vehicle is first powered on after leaving the factory or when the vehicle receives a preset initialization command, the preset hydrogen consumption per unit mileage obtained from testing under preset operating conditions is used as the second hydrogen consumption per unit mileage. Based on this, after the vehicle is first powered on after leaving the factory, the preset hydrogen consumption per unit mileage can be iteratively corrected based on the hydrogen consumption per unit mileage corresponding to the preset mileage to obtain the target hydrogen consumption per unit mileage, thus ensuring the accuracy of the obtained target hydrogen consumption per unit mileage. After receiving the preset initialization command, the second hydrogen consumption per unit mileage is initialized to the preset hydrogen consumption per unit mileage, thereby ensuring that the hydrogen consumption per unit mileage calculated iteratively before receiving the initialization command will not participate in the calculation process of the vehicle's hydrogen consumption per unit mileage after receiving the initialization command. This improves the accuracy of the determination of the vehicle's hydrogen consumption per unit mileage and ensures that the determined hydrogen consumption per unit mileage meets the user's actual needs.

[0095] Furthermore, in the above embodiments, the method for determining information of the hydrogen fuel cell vehicle further includes the following steps: when the vehicle operation meets preset conditions, determining the preset hydrogen consumption per unit mile as the target hydrogen consumption per unit mile; when the vehicle operation does not meet the preset conditions, performing the step of obtaining the hydrogen consumption and driving mileage of the vehicle where the hydrogen fuel cell system is located from the initial first moment to the current second moment; wherein, the preset conditions include receiving a preset initialization command or the vehicle being powered on for the first time after leaving the factory.

[0096] The preset initialization command is used to initialize the vehicle's current target hydrogen consumption per unit mile. In this embodiment, the preset initialization command is input by the user through a button on the instrument panel (which can be a physical button or a virtual button). In other embodiments, the preset initialization command can also be input by the user through a mobile terminal connected to the vehicle.

[0097] Furthermore, when the vehicle operation meets the preset conditions, the preset hydrogen consumption per unit mile is determined to be the target hydrogen consumption per unit mile, and the process can return to step S10.

[0098] In this embodiment, when the vehicle receives a preset initialization command or is powered on for the first time after leaving the factory, the preset hydrogen consumption per unit mile is determined as the target hydrogen consumption per unit mile; at other times, the target hydrogen consumption per unit mile is determined according to the method mentioned in the above embodiment. Based on this, it is beneficial to ensure the accuracy of the target hydrogen consumption per unit mile determined for any vehicle.

[0099] Furthermore, based on any of the above embodiments, another embodiment of the method for determining information of hydrogen fuel cell vehicles according to this application is proposed. In this embodiment, reference is made to... Figure 4 Step S10 includes:

[0100] Step S11: Obtain the remaining hydrogen quantity of the hydrogen fuel cell system corresponding to the first time and the second time respectively, wherein the remaining hydrogen quantity corresponding to the first time is the first remaining hydrogen quantity, and the remaining hydrogen quantity corresponding to the second time is the second remaining hydrogen quantity.

[0101] The first remaining hydrogen quantity represents the amount of hydrogen remaining in the hydrogen fuel cell system at the first moment. The second remaining hydrogen quantity represents the amount of hydrogen remaining in the hydrogen fuel cell system at the second moment.

[0102] The first and second remaining hydrogen quantities can be values ​​determined based on the internal state parameters of the hydrogen fuel cell system detected in real time at the corresponding moment, or values ​​determined based on the internal state parameters of multiple hydrogen fuel cell systems detected within a preset time period at the corresponding moment.

[0103] It should be noted that the concepts of hydrogen quantity, remaining hydrogen quantity, hydrogen consumption, and hydrogen consumption per unit mileage mentioned in this embodiment, as well as the hydrogen quantity mentioned in any of the above embodiments, all refer to the mass of hydrogen.

[0104] Step S12: Determine the hydrogen consumption based on the difference between the first remaining hydrogen quantity and the second remaining hydrogen quantity.

[0105] Specifically, the difference between the first remaining hydrogen quantity and the second remaining hydrogen quantity is taken as the hydrogen consumption.

[0106] In this embodiment, the hydrogen consumption is determined based on the remaining hydrogen amount at the first and second time points, which helps to further improve the accuracy of the subsequently determined target hydrogen consumption per unit mileage.

[0107] Furthermore, in this embodiment, referring to Figure 4 Before step S10, the method further includes defining the second time point and the first time point as target times, respectively:

[0108] Step S01: Continuously monitor the internal state parameters of the hydrogen fuel cell system;

[0109] In this embodiment, the internal state parameters include the pressure and temperature data of hydrogen inside the hydrogen storage tank in the hydrogen fuel cell system. In other embodiments, the internal state parameters may also include one of the pressure and temperature data of hydrogen inside the hydrogen storage tank in the hydrogen fuel cell system, or other parameters besides pressure and temperature data.

[0110] Specifically, the internal state parameters can be obtained by reading data from the pressure sensor and temperature sensor at set intervals.

[0111] Step S02: Determine a reference value for the remaining amount of hydrogen in the hydrogen fuel cell system based on the internal state parameters, and determine the difference between the reference value and the initial value; the initial value is the remaining amount of hydrogen in the hydrogen fuel cell system determined based on the internal state parameters at the time the vehicle is powered on.

[0112] Step S03: When the difference satisfies the first condition or the second condition, the reference value corresponding to the target time is determined to be the amount of remaining hydrogen at the target time.

[0113] Step S04: When the difference does not meet the first condition and the second condition, the initial value is determined to be the amount of remaining hydrogen corresponding to the target time.

[0114] The first condition includes the difference corresponding to the target time being less than or equal to a first preset threshold, and the difference being continuously less than or equal to the first preset threshold within a first preset duration before the target time. The second condition includes the difference corresponding to the target time being greater than or equal to the second preset threshold, and the difference being continuously greater than or equal to the second preset threshold within a second preset duration before the target time. The first preset threshold is less than the second preset threshold.

[0115] In this embodiment, the first condition characterizes the consumption state of the hydrogen fuel cell system. The second condition characterizes the hydrogen refueling state of the hydrogen fuel cell system. The first preset threshold is less than 0, and the second preset threshold is greater than 0. The first preset duration is less than the second preset duration. In other embodiments, the first preset duration may also be greater than or equal to the second preset duration.

[0116] The first preset duration before the target time specifically refers to the time period from the target time to the time interval of the first preset duration before the target time, with the target time as the start time and the target time as the end time. The second preset duration before the target time specifically refers to the time period from the target time to the time interval of the second preset duration before the target time, with the target time as the start time and the target time as the end time.

[0117] Furthermore, the absolute value of the first preset threshold is less than the absolute value of the second preset threshold.

[0118] For example, the reference value corresponding to different times Ti (i takes the value [1, 2, ..., n]) is mi, the interval between two adjacent Ti is the set duration mentioned above, the initial value of the power-on time T1 is m1, the reference value corresponding to the target time Tn is mn, and the first preset duration is ΔT1. Based on this:

[0119] If the difference mn-m1 ≤ P1 (P1 < 0), and mi-m1 remains ≤ P1 from time Tn-ΔT1 to Tn, then the remaining amount of hydrogen at the target time Tn is mn; otherwise, the remaining amount of hydrogen at the target time Tn is m1.

[0120] If the difference mn-m1 > P2 (P2 > 0), and mi-m1 continues to be greater than P2 from time Tn-ΔT1 to Tn, then the remaining amount of hydrogen at the target time Tn is mn; otherwise, the remaining amount of hydrogen at the target time Tn is m1.

[0121] In this embodiment, the reference value of the remaining hydrogen quantity determined based on the internal state parameters of the hydrogen fuel cell system is not directly used as the remaining hydrogen quantity of the hydrogen fuel cell system. Instead, the reference value at the target time is determined by combining the difference between the remaining hydrogen quantity determined based on the internal state parameters at the target time and the initial time, as well as the duration of this difference. Furthermore, different conditions are formulated to consider the different effects of hydrogen consumption and refueling status on the remaining hydrogen quantity of the hydrogen fuel cell system. The remaining hydrogen quantity is determined by combining the difference between the different conditions and the target time. Compared with directly using the reference value at the target time as the remaining hydrogen quantity, this method can effectively avoid short-term fluctuations in the determined remaining hydrogen quantity caused by fluctuations in internal state parameters such as pressure and temperature. This prevents instability in vehicle information related to the remaining hydrogen quantity (such as the target hydrogen consumption per unit mile, subsequent driving range, refueling reminder timing, etc.). Based on this, it is beneficial to further improve the accuracy and stability of the target hydrogen consumption per unit mile determined based on the remaining hydrogen quantity.

[0122] In other embodiments, the reference value corresponding to the target time can also be directly used as the corresponding remaining hydrogen quantity.

[0123] Furthermore, in this embodiment, after obtaining the second remaining hydrogen quantity corresponding to the second time point, the method further includes: outputting a first prompt message corresponding to the second remaining hydrogen quantity. The first prompt message may include forms such as display, sound, and / or light. Specifically, the first remaining hydrogen quantity is displayed on the vehicle's instrument panel. Based on this, the user can obtain an accurate amount of remaining hydrogen in the hydrogen fuel cell system based on the first prompt message.

[0124] Furthermore, based on any of the above embodiments, another embodiment of the method for determining information of hydrogen fuel cell vehicles according to this application is proposed. In this embodiment, reference is made to... Figure 5 After step S30, the method further includes:

[0125] Step S60: Determine the available hydrogen quantity of the hydrogen fuel cell system based on the deviation between the remaining hydrogen quantity of the hydrogen fuel cell system at the second moment and the preset hydrogen quantity; wherein, the preset hydrogen quantity is the minimum amount of hydrogen required for the normal operation of the hydrogen fuel cell system.

[0126] The amount of remaining hydrogen at the second moment can be determined according to steps S01 to S04 and their detailed steps, which will not be elaborated here.

[0127] The preset hydrogen quantity refers to pre-calibrated parameters. Specifically, as hydrogen is consumed, when the pressure in the hydrogen storage tank of the hydrogen fuel cell system drops to a certain threshold and can no longer stably supply hydrogen, the hydrogen fuel cell stops supplying power. The remaining hydrogen quantity at this time can be used as the preset hydrogen quantity.

[0128] Specifically, the deviation between the second remaining hydrogen quantity at the second time point and the preset hydrogen quantity can be used as the available hydrogen quantity. In other embodiments, the result after further correcting the deviation according to a preset coefficient can also be used as the available hydrogen quantity.

[0129] Step S70: Determine the vehicle's driving range based on the available hydrogen quantity and the target hydrogen consumption per unit mileage;

[0130] Specifically, the ratio of available hydrogen to the target hydrogen consumption per unit mile can be determined, and the driving range is calculated by multiplying the ratio by the unit mile corresponding to the target hydrogen consumption per unit mile.

[0131] Step S80: Output the second prompt information corresponding to the remaining driving range.

[0132] The second notification may take the form of display, sound, and / or light. In this embodiment, the remaining driving range is displayed on the instrument panel.

[0133] In this embodiment, by taking the above steps, it is beneficial to further improve the accuracy of the driving range while increasing the hydrogen consumption per unit mileage.

[0134] It should be noted that when the vehicle operation meets the preset conditions, after determining the preset hydrogen consumption per unit mile as the target hydrogen consumption per unit mile, steps S60 to S80 here can also be executed.

[0135] It should be noted that when steps S40 and S50 are included after step S30, steps S60 to S70 are executed first after step S30 and before returning to execute step S10.

[0136] Furthermore, based on any of the above embodiments, another embodiment of the method for determining information of hydrogen fuel cell vehicles according to this application is proposed. In this embodiment, reference is made to... Figure 6After step S30, the method further includes:

[0137] Step S91: Obtain the remaining mileage at the time of the hydrogen refueling prompt set by the user;

[0138] The remaining mileage can be determined by the user's input via buttons or voice commands.

[0139] Step S92: Determine the hydrogen quantity threshold when the vehicle is prompted to refuel based on the remaining mileage and the target hydrogen consumption per unit mileage;

[0140] The hydrogen quantity threshold is the minimum amount of hydrogen remaining in the hydrogen fuel cell system that the vehicle needs to reach when the hydrogen refueling prompt is triggered.

[0141] Different remaining mileage and different target hydrogen consumption per unit mile correspond to different hydrogen consumption thresholds. Specifically, the ratio of remaining mileage to the unit mileage corresponding to the target hydrogen consumption per unit mile can be determined, and the product of this ratio and the target hydrogen consumption per unit mile can be used as the hydrogen consumption threshold.

[0142] Step S93: When the remaining hydrogen amount of the hydrogen fuel cell system at the second time point is less than or equal to the hydrogen amount threshold, output hydrogen refueling prompt information.

[0143] The amount of remaining hydrogen at the current second moment can be determined in the manner mentioned in the above embodiments, and will not be repeated here.

[0144] If the remaining hydrogen supply in the hydrogen fuel cell system is less than or equal to the hydrogen supply threshold at any given time, the system can control the prompting device to output a hydrogen refueling prompt message. This message specifically serves to remind the vehicle's user to refuel.

[0145] Hydrogen refueling prompts may include visual, audio, and / or light prompts. Specifically, hydrogen refueling prompts may be displayed on the display panel.

[0146] In this embodiment, the hydrogen quantity threshold that triggers the hydrogen refueling prompt is no longer a pre-set fixed value, but is determined by combining the user-set remaining mileage and the aforementioned target hydrogen consumption per unit mileage. The accuracy of the target hydrogen consumption per unit mileage helps improve the accuracy of the hydrogen quantity threshold, thereby improving the precision of the timing of the hydrogen refueling prompt. Furthermore, the application of the user-set remaining mileage avoids the user's inability to accurately perceive the mileage allowed by the remaining hydrogen quantity, which would lead to an inability to accurately determine the timing of hydrogen refueling after the prompt. At the same time, it effectively avoids a mismatch between the vehicle's hydrogen refueling prompt and the user's actual mileage needs, ensuring that the hydrogen refueling prompt accurately matches the user's actual driving mileage needs. This allows the user to promptly know the vehicle's remaining mileage based on the hydrogen refueling prompt information and refuel in a timely manner, which is conducive to further improving the matching degree between hydrogen fuel cell vehicles and user use.

[0147] It should be noted that when the vehicle operation meets the preset conditions, after determining the preset hydrogen consumption per unit mile as the target hydrogen consumption per unit mile, steps S91 to S93 can also be executed here. In addition, when steps S40 and S50 are included after step S30, steps S91 to S93 are executed first after step S30 and before returning to execute step S10.

[0148] It should be further noted that after step S30 or when the vehicle operation meets the preset conditions, after the step of determining the preset unit mile hydrogen consumption as the target unit mile hydrogen consumption, the order of execution of steps S91 to S93 and the above-mentioned steps S60 to S80 is not specifically limited.

[0149] Furthermore, this embodiment of the invention also proposes a storage medium storing a hydrogen fuel cell vehicle information determination program. When the hydrogen fuel cell vehicle information determination program is executed by a processor, it implements the relevant steps of any embodiment of the above-described hydrogen fuel cell vehicle information determination method.
