Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method for determining vehicle information, a device for determining vehicle information, and a storage medium. Background Technology

[0002] With the development of economy and technology, the power sources of vehicles are becoming more and more diversified. Among them, the amount of hydrogen consumed per unit distance (e.g., hydrogen consumption per 100 kilometers) in vehicles equipped with hydrogen fuel cell systems is an important performance indicator.

[0003] Currently, vehicles equipped with hydrogen fuel cell systems typically calculate hydrogen consumption per unit mileage based on the vehicle's mileage and the amount of hydrogen consumed within a fixed time period. However, when a vehicle is also equipped with a power battery system as a power source, the vehicle's operating conditions are diverse. The hydrogen consumption per unit mile calculated using this method deviates significantly from the actual hydrogen consumption per unit mileage, making it impossible to accurately evaluate the vehicle's actual performance. Summary of the Invention

[0004] The main objective of this invention is to provide a vehicle information determination method, a vehicle information determination device, and a storage medium, aiming to improve the accuracy of the obtained vehicle hydrogen consumption per unit mileage and improve the accuracy of vehicle performance evaluation.

[0005] To achieve the above objectives, the present invention provides a vehicle information determination method, the vehicle information determination method comprising the following steps:

[0006] The vehicle's mileage during a target time period, the change in the remaining charge of the vehicle's power battery system during the target time period, and the hydrogen consumption of the vehicle's hydrogen fuel cell system during the target time period are obtained.

[0007] The target hydrogen consumption per unit mileage of the vehicle is determined based on the change in remaining battery power, the driving mileage, and the hydrogen consumption.

[0008] Optionally, the step of determining the target hydrogen consumption per unit mileage of the vehicle based on the change in remaining battery power, the driving mileage, and the hydrogen consumption includes:

[0009] The driving range is adjusted based on the change in the remaining battery power to obtain the corrected range;

[0010] The target hydrogen consumption per unit mileage is determined based on the hydrogen consumption and the corrected mileage.

[0011] Optionally, when the change in remaining battery power corresponds to an increase in remaining battery power, the corrected mileage is greater than the driving mileage;

[0012] When the remaining battery power decreases corresponding to the change in remaining battery power, the corrected mileage is less than the driving mileage.

[0013] Optionally, the steps of obtaining the vehicle's mileage during the target time period, the change in the remaining charge of the vehicle's power battery system during the target time period, and the hydrogen consumption of the vehicle's hydrogen fuel cell system during the target time period include:

[0014] Obtain the vehicle's driving state parameters between the current first moment and the second moment prior to the first moment;

[0015] When the driving status parameters meet the preset conditions, the time period between the first moment and the second moment is determined as the target time period, and the driving mileage, the change value of the remaining power and the hydrogen consumption corresponding to the target time period are obtained.

[0016] Optionally, the step of obtaining the vehicle's driving state parameters between the current first moment and a second moment prior to the first moment includes:

[0017] Obtain the operating status of the vehicle's energy recovery operation;

[0018] When the operating state is on, the mileage traveled by the vehicle between the first time and the second time is obtained;

[0019] When the operating state is off, the change in the remaining charge of the power battery system between the first time and the second time is obtained;

[0020] The driving status parameters include the mileage or the change value.

[0021] Optionally, the preset conditions include the mileage being greater than or equal to a preset mileage or the change value being greater than or equal to a preset power change value.

[0022] Optionally, after determining the target hydrogen consumption per unit mileage of the vehicle based on the change in remaining battery power, the driving mileage, and the hydrogen consumption, the method further includes:

[0023] The first driving range of the vehicle is determined based on the target hydrogen consumption per unit mileage and the available hydrogen quantity of the hydrogen fuel cell system.

[0024] The second driving range of the vehicle is determined based on the remaining charge of the power battery system and the power consumption per unit mileage.

[0025] Output prompt information based on the first driving range and the second driving range.

[0026] Optionally, the step of outputting prompt information based on the first driving range and the second driving range includes:

[0027] Output the first prompt message corresponding to the first driving range, and output the second prompt message corresponding to the second driving range;

[0028] Alternatively, a third driving range can be determined based on the first driving range and the second driving range, and a third prompt message corresponding to the third driving range can be output.

[0029] Optionally, the vehicle information determination method further includes:

[0030] Obtain the power supply mode of the vehicle;

[0031] When the power supply mode is a preset mode, the hydrogen consumption per unit mileage detected when the vehicle switches to the preset mode is determined as the target hydrogen consumption per unit mileage.

[0032] When the power supply mode is a mode other than the preset mode, the steps of obtaining the vehicle's driving mileage in the target time period, the change value of the remaining charge of the vehicle's power battery system in the target time period, and the hydrogen consumption of the vehicle's hydrogen fuel cell system in the target time period are executed.

[0033] In the preset mode, the power battery system is used alone for power supply.

[0034] Optionally, before the step of determining the second driving range of the vehicle based on the remaining charge of the power battery system and the power consumption per unit mileage, the method further includes:

[0035] The output mode for obtaining the vehicle's driving range;

[0036] When the output mode is the standard mode, the first driving range of the vehicle is determined based on the standard hydrogen consumption per unit mileage and the available hydrogen quantity of the hydrogen fuel cell system.

[0037] When the output mode is adaptive mode, the first driving range of the vehicle is determined based on the target hydrogen consumption per unit mileage and the available hydrogen quantity of the hydrogen fuel cell system.

[0038] In addition, to achieve the above objectives, this application also proposes a vehicle information determination device, which includes: a memory, a processor, and a vehicle information determination program stored in the memory and executable on the processor. When the vehicle information determination program is executed by the processor, it implements the steps of the vehicle information determination method as described in any of the preceding claims.

[0039] In addition, to achieve the above objectives, this application also proposes a storage medium storing a vehicle information determination program, which, when executed by a processor, implements the steps of the vehicle information determination method as described in any of the preceding claims.

[0040] This invention proposes a vehicle information determination method that combines the vehicle's mileage within a target time period, the change in the remaining charge of the power battery system, and hydrogen consumption to determine the vehicle's target hydrogen consumption per unit mileage, rather than solely relying on the detected mileage and hydrogen consumption. The obtained target hydrogen consumption per unit mileage accurately reflects the impact of the power battery system's operation on the hydrogen fuel cell system's hydrogen consumption under different operating conditions, and is more closely aligned with the vehicle's actual hydrogen consumption per unit mileage. This effectively improves the accuracy of the obtained vehicle hydrogen consumption per unit mileage and enhances the accuracy of vehicle performance evaluation. Attached Figure Description

[0047] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0048] This invention provides a vehicle information determination device 1. In this embodiment, the vehicle information determination device 1 is the vehicle itself. In other embodiments, the vehicle information determination device 1 may also be an external device that is communicatively connected to the vehicle (e.g., a driver's mobile terminal).

[0049] In this embodiment of the invention, reference is made to Figure 1The vehicle information determination device 1 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.

[0050] In this embodiment, the vehicle information determination device 1 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 2. The third module is used to acquire the hydrogen consumption per unit mile, 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 mile, 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 vehicle information determination device 1 may also be a device that integrates the first module, the second module, and the third module.

[0051] Those skilled in the art will understand that Figure 1 The 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.

[0052] like Figure 1 As shown, the memory 1002, which serves as a storage medium, may include a vehicle information determination program. Figure 1 In the device shown, the processor 1001 can be used to call the vehicle information determination program stored in the memory 1002 and execute the relevant steps of the vehicle information determination method in the following embodiments.

[0053] The present invention also proposes a vehicle.

[0054] In this embodiment of the invention, reference is made to Figure 1 The vehicle includes a vehicle information determination device 1, a hydrogen fuel cell system 2, an odometer 3, a detection module 4, a warning device 5, and a power battery system 6. The odometer 3, detection module 4, warning device 5, and power battery system 6 are all connected to the vehicle information determination device 1. The vehicle information determination device 1 can be used to acquire data detected by the odometer 3 and the detection module 4, and can also be used to control the warning device 5 to output and display information.

[0055] The hydrogen fuel cell system 2 and the power battery system 6 can function independently as the vehicle's power supply system, or they can function simultaneously as the vehicle's power supply system. Specifically, the hydrogen fuel cell system 2 can be used to charge the power battery system 6.

[0056] The odometer 3 is used to calculate the vehicle's mileage. The detection module 4 is located within the hydrogen fuel cell system 2 and is used to detect the internal state parameters of the hydrogen fuel cell system 2. In this embodiment, the detection module 4 includes a pressure sensor and a temperature sensor. The pressure sensor is used to detect the pressure information in the hydrogen storage tank of the hydrogen fuel cell system 2, and the temperature sensor is used to detect the temperature information in the hydrogen storage tank of the hydrogen fuel cell system 2.

[0057] 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.

[0058] This invention also provides a vehicle information determination method, applied to the aforementioned vehicle information determination device.

[0059] Reference Figure 2 This application proposes an embodiment of a vehicle information determination method. In this embodiment, the vehicle information determination method includes:

[0060] Step S10: Obtain the vehicle's mileage during the target time period, the change in the remaining charge of the vehicle's power battery system during the target time period, and the hydrogen consumption of the vehicle's hydrogen fuel cell system during the target time period.

[0061] In this embodiment, the target time period is the time during which the vehicle's driving status parameters meet preset conditions, and it is a time period of variable duration. In other embodiments, the target time period may also be a pre-set time period of fixed duration.

[0062] In this embodiment, the end time of the target time period is the current time. In other embodiments, the target time period may also be a time period prior to the current time.

[0063] The start time of the target time period can be the moment the vehicle is powered on, the moment the vehicle reaches the preset conditions after being powered on, or the moment a preset command is received from the user.

[0064] The mileage is the total distance the vehicle travels within the target time period. The mileage detected by the odometer at the beginning of the target time period is defined as the first mileage, and the mileage detected by the odometer at the end of the target time period is defined as the second mileage. The mileage can be determined based on the difference between the second mileage and the first mileage.

[0065] Hydrogen consumption refers to the total amount of hydrogen consumed by the vehicle within a target time period. 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 target time period belongs 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 start time and the amount of hydrogen remaining in the hydrogen fuel cell system detected at the end time of the target time period. Alternatively, the intermediate time within the target time period before the start and end times can be determined, and the hydrogen consumption can be determined based on the amount of hydrogen remaining in the hydrogen fuel cell system corresponding to the start time, intermediate time, and end time, respectively.

[0066] The change in remaining battery capacity is a characteristic value representing the change in the remaining battery capacity of the power battery system within a target time period. The remaining battery capacity at the beginning of the target time period is defined as the first battery capacity, and the remaining battery capacity at the end of the target time period is defined as the second battery capacity. The change in remaining battery capacity is determined based on the difference between the second and first battery capacities. A positive change in remaining battery capacity indicates that the remaining battery capacity has increased within the target time period, while a negative change in remaining battery capacity indicates that the remaining battery capacity has decreased within the target time period.

[0067] Step S20: Determine the target hydrogen consumption per unit mileage of the vehicle based on the remaining power change value, the driving mileage, and the hydrogen consumption.

[0068] The target hydrogen consumption per unit mile is the average amount of hydrogen consumed by the hydrogen fuel cell system when the vehicle travels a unit mile. In this embodiment, the unit mile is 100 kilometers, so the target hydrogen consumption per unit mile is the average amount of hydrogen consumed by the hydrogen fuel cell system when the vehicle travels 100 kilometers. In other embodiments, the unit mile can also be other values, such as 1000 kilometers, 10 kilometers, 1 kilometer, etc.

[0069] A pre-established correspondence between the remaining battery power change value, driving mileage, hydrogen consumption and target hydrogen consumption per unit mileage is established. This correspondence may include calculation formulas, mapping relationships, etc. Based on this correspondence, the target hydrogen consumption per unit mileage corresponding to the remaining battery power change value, driving mileage and hydrogen consumption can be determined.

[0070] In one implementation of this embodiment, the driving range is corrected based on the change in remaining battery power to obtain the corrected range, and the target hydrogen consumption per unit mileage is determined based on the corrected range and hydrogen consumption.

[0071] In another implementation of this embodiment, the hydrogen consumption is corrected based on the change in remaining electricity to obtain the corrected hydrogen consumption, and the target hydrogen consumption per unit mileage is determined based on the corrected hydrogen consumption and the driving mileage.

[0072] In another implementation of this embodiment, the driving range is corrected based on the change in remaining battery power to obtain the corrected mileage, the hydrogen consumption is corrected based on the change in remaining battery power to obtain the corrected hydrogen consumption, and the target hydrogen consumption per unit mileage is determined based on the corrected hydrogen consumption and the corrected mileage.

[0073] This invention proposes a vehicle information determination method that combines the vehicle's mileage within a target time period, the change in the remaining charge of the power battery system, and hydrogen consumption to determine the vehicle's target hydrogen consumption per unit mileage, rather than solely relying on the detected mileage and hydrogen consumption. The obtained target hydrogen consumption per unit mileage accurately reflects the impact of the power battery system's operation on the hydrogen fuel cell system's hydrogen consumption under different operating conditions, and is more closely aligned with the vehicle's actual hydrogen consumption per unit mileage. This effectively improves the accuracy of the obtained vehicle hydrogen consumption per unit mileage and enhances the accuracy of vehicle performance evaluation.

[0074] Furthermore, based on the above embodiments, another embodiment of the vehicle information determination method of this application is proposed.

[0075] In this embodiment, refer to Figure 3 Step S20 includes:

[0076] Step S21: Correct the driving range based on the change in remaining battery power to obtain the corrected range;

[0077] The mileage correction value is determined based on the change in remaining battery power, and the corrected mileage is obtained by increasing or decreasing the driving mileage based on the mileage correction value.

[0078] Different changes in remaining battery power correspond to different mileage correction values. Specifically, a pre-established correspondence between changes in remaining battery power and mileage correction values ​​can be established. This correspondence can include calculation relationships, mapping relationships, etc., and the mileage correction value corresponding to the change in remaining battery power can be determined based on this correspondence. For example, the mileage correction value can be calculated by substituting the change in remaining battery power into a preset formula; or it can be obtained by looking up the change in remaining battery power in a table, and so on.

[0079] In this embodiment, the power consumption per unit mile of the power battery system is obtained, and the ratio of the change in remaining power to the power consumption per unit mile is used as the mileage correction value. The power consumption per unit mile can be the WLTC power consumption report value, or the power consumption value obtained according to a certain experimental cycle test, or the power consumption per unit mile can be the average power consumption value calculated cumulatively based on parameters collected during vehicle driving, etc.

[0080] For example, the mileage correction value Δd SOC= (SOC2 - SOC1) / PC, where SOC2 is the remaining charge of the power battery system at the end of the target time period, SOC1 is the remaining charge of the power battery system at the beginning of the target time period, (SOC2 - SOC1) is the change in remaining charge, and PC is the power consumption per unit distance. Corrected mileage d = d1 + Δd SOC d1 represents the mileage traveled within the target time period.

[0081] Step S22: Determine the target hydrogen consumption per unit mileage based on the hydrogen consumption and the corrected mileage.

[0082] The ratio of hydrogen consumption to corrected mileage is determined as the first unit mileage hydrogen consumption of the vehicle within the target time period, and the target unit mileage hydrogen consumption is determined based on the first unit mileage hydrogen consumption.

[0083] In this embodiment, the target hydrogen consumption per unit mileage of the vehicle is determined 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 determined based on the preset hydrogen consumption per unit mileage obtained by pre-testing under preset operating conditions.

[0084] In other embodiments, the hydrogen consumption per unit mileage can also be directly used as the target hydrogen consumption per unit mileage.

[0085] In other embodiments, the target unit mileage hydrogen consumption can also be determined based on the first unit mileage hydrogen consumption corresponding to a preset number of target time periods prior to the current time.

[0086] In this embodiment, the corrected mileage is obtained by correcting the remaining charge change value. The obtained corrected mileage can eliminate the influence of the power battery system operation and accurately reflect the mileage contributed by the hydrogen fuel cell system in the target time period. Based on this, the target hydrogen consumption per unit mileage is determined by combining the corrected mileage and hydrogen consumption, which helps to further improve the accuracy of the obtained hydrogen consumption per unit mileage of the vehicle and improve the accuracy of vehicle performance evaluation.

[0087] Furthermore, in this embodiment, when the remaining power change value corresponds to an increase in the remaining power, the corrected mileage is greater than the driving mileage; when the remaining power change value corresponds to a decrease in the remaining power, the corrected mileage is less than the driving mileage.

[0088] When SOC2 > SOC1, it indicates that the hydrogen fuel cell system is charging the power battery system, and the range correction value Δd SOCThe value is positive, and the corrected mileage is greater than the driving mileage. The electricity generated by the hydrogen fuel cell system during the charging process is converted into the corresponding mileage correction value and added to the driving mileage. This ensures that the hydrogen consumption per unit mileage calculated based on the corrected mileage can accurately reflect the actual hydrogen consumption of the hydrogen fuel cell system, thereby further improving the accuracy of the determined hydrogen consumption per unit mileage of the vehicle.

[0089] When SOC2 < SOC1, it indicates that the power battery system supplies power during vehicle operation, and the range correction value Δd SOC If the value is negative, the corrected mileage is less than the driving mileage. The amount of electricity consumed by the power battery system during driving is converted into the corresponding mileage correction value and deducted from the driving mileage. This ensures that the hydrogen consumption per unit mileage calculated based on the corrected mileage can accurately reflect the actual hydrogen consumption of the hydrogen fuel cell system, thereby further improving the accuracy of the determined hydrogen consumption per unit mileage of the vehicle.

[0090] Furthermore, based on any of the above embodiments, another embodiment of the vehicle information determination method of this application is proposed. In this embodiment, reference is made to... Figure 4 Step S10 includes:

[0091] Step S11: Obtain the driving state parameters of the vehicle between the current first moment and the second moment before the first moment;

[0092] The driving status parameters here specifically refer to the status parameters related to the operation of the vehicle's battery system during vehicle operation.

[0093] Driving status parameters may include the state of charge parameters of the power battery system and / or the mileage traveled by the vehicle. These driving status parameters can be preset fixed parameters or parameters selected based on the actual operating conditions of the vehicle.

[0094] The second moment here can be the moment the vehicle is powered on, the moment when the vehicle last drove and reached the preset condition (which is the same concept as the preset condition in step S12), or the moment when the preset command input by the user is received.

[0095] Specifically, at the second moment, the state parameters of the vehicle during its driving process can be detected as the first parameter. Then, the state parameters of the vehicle during its driving process can be detected at set intervals, and the state parameters of the vehicle during its driving process detected at the current moment can be used as the second parameter to determine whether the first parameter and the second parameter meet the preset conditions.

[0096] Step S12: When the driving status parameters meet the preset conditions, determine the time period between the first time and the second time as the target time period, and obtain the driving mileage, the change value of the remaining power, and the hydrogen consumption corresponding to the target time period.

[0097] Preset conditions can be fixed conditions set in advance, or conditions selected based on the actual operating conditions of the vehicle. Different driving state parameters require different preset conditions. Preset conditions may include the target value range that the driving state parameters need to reach, or the target relationship between the parameters and preset parameter thresholds, etc.

[0098] If the driving status parameters meet the preset conditions, it indicates that the detected driving mileage, remaining battery power change value, and hydrogen consumption between the first and second moments are accurate. At this time, using the first and second moments as the target time period to further determine the corresponding driving mileage, remaining battery power change value, and hydrogen consumption for the vehicle's target unit mileage hydrogen consumption is beneficial to further improve the accuracy of determining the unit mileage hydrogen consumption.

[0099] Furthermore, in this embodiment, step S11 includes: obtaining the operating status of the energy recovery operation of the vehicle; when the operating status is on, obtaining the mileage traveled by the vehicle between the first time and the second time; when the operating status is off, obtaining the change value of the remaining charge of the power battery system between the first time and the second time; wherein, the driving status parameter includes the mileage or the change value.

[0100] The mileage detected by the vehicle's odometer at the first moment is the third mileage, and the mileage detected by the vehicle's odometer at the second moment is the fourth mileage. The difference between the third mileage and the fourth mileage is used as the mileage here.

[0101] The remaining charge of the power battery system at the first moment is the third charge, and the remaining charge of the power battery system at the second moment is the fourth charge. The difference between the third charge and the fourth charge is the change value here.

[0102] When the vehicle is in the first mode (such as passion mode), the energy recovery operation is activated when the vehicle is in a coasting or braking state. At this time, the energy recovered may come from the hydrogen fuel cell system and / or the power battery system. At this time, the target time period is determined based on the mileage traveled by the vehicle between the first and second moments to obtain relevant parameters. This helps to avoid calculation errors caused by energy recovery and further improves the accuracy of the calculation of hydrogen consumption per unit mileage.

[0103] When the vehicle is in the second mode (such as comfort mode), the energy recovery operation is turned off when the vehicle is in a coasting or braking state. At this time, there is no energy to recover to charge the power battery system. The target time period is determined based on the change in the remaining charge of the power battery system between the first and second moments to obtain relevant parameters, which helps to further improve the accuracy of the calculation of hydrogen consumption per unit mileage.

[0104] Furthermore, in this embodiment, the preset conditions include the mileage being greater than or equal to a preset mileage or the change value being greater than or equal to a preset power change value. Based on this, step S12 includes:

[0105] When the driving status parameters include the mileage and the mileage is greater than or equal to the preset mileage, the time period between the first moment and the second moment is determined as the target time period, the mileage is determined as the driving mileage, and the remaining power change value and the hydrogen consumption corresponding to the target time period are obtained.

[0106] When the driving status parameters include the change value, and the change value is greater than or equal to the preset battery change value, the time period between the first moment and the second moment is determined as the target time period, the change value is determined as the remaining battery change value, and the driving mileage and hydrogen consumption corresponding to the target time period are obtained.

[0107] In this embodiment, when energy recovery is enabled, the detection data within a certain time period is applied to the calculation of hydrogen consumption per unit mileage only when the driving distance is sufficiently large. This helps avoid deviations in the calculation of hydrogen consumption per unit mileage caused by vehicle idling and energy recovery, thereby effectively improving the accuracy of the obtained hydrogen consumption per unit mileage. This ensures accurate evaluation of vehicle performance, such as driving range, based on the obtained target hydrogen consumption per unit mileage, and improves the accuracy of vehicle performance evaluation. When energy recovery is disabled, the detection data within a certain time period is applied to the calculation of hydrogen consumption per unit mileage only when the remaining battery power changes sufficiently. This allows for timely calculation of hydrogen consumption per unit mileage when the battery power fluctuates, improving the timeliness of the obtained hydrogen consumption per unit mileage and enhancing the timeliness of vehicle performance evaluation.

[0108] In other embodiments, the preset conditions may also include the difference between the mileage and the preset mileage being greater than a preset value, or the difference between the change value and the preset change value of electricity being greater than a preset value, and so on.

[0109] Furthermore, based on any of the above embodiments, another embodiment of the vehicle information determination method of this application is proposed. In this embodiment, reference is made to... Figure 5 After step S20, the following steps are also included:

[0110] Step S30: Determine the first driving range of the vehicle based on the target hydrogen consumption per unit mileage and the available hydrogen quantity of the hydrogen fuel cell system;

[0111] The available hydrogen quantity can be determined by directly detecting the remaining hydrogen quantity through a detection device, or it can be obtained by correcting the remaining hydrogen quantity obtained by direct detection.

[0112] In this embodiment, the available hydrogen quantity of the hydrogen fuel cell system is determined based on the deviation between the remaining hydrogen quantity at the current 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. The preset hydrogen quantity is specifically a pre-calibrated parameter. 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 cannot stably supply hydrogen, the hydrogen fuel cell system stops supplying power; the remaining hydrogen quantity at this time can be used as the preset hydrogen quantity.

[0113] Specifically, the ratio of available hydrogen to the target hydrogen consumption per unit mile can be determined, and the product of the ratio and the unit mile corresponding to the target hydrogen consumption per unit mile is used as the first driving range.

[0114] Step S40: Determine the second driving range of the vehicle based on the remaining power of the power battery system and the power consumption per unit mileage;

[0115] The power consumption per unit mileage can be the WLTC power consumption announcement value, or the power consumption per unit mileage can be the power consumption value obtained by a certain experimental cycle test, or the power consumption per unit mileage can be the average power consumption value calculated cumulatively based on parameters collected during vehicle driving, and so on.

[0116] The remaining battery power here refers to the parameter detected at the current moment.

[0117] In this embodiment, the ratio of remaining battery power to power consumption per unit distance is used as the second driving range.

[0118] Step S50: Output prompt information based on the first driving range and the second driving range.

[0119] The notification information may take the form of display, sound, and / or light. In this embodiment, the remaining driving range is displayed on the instrument panel.

[0120] In one implementation of this embodiment, a first prompt message corresponding to the first driving range is output, and a second prompt message corresponding to the second driving range is output.

[0121] In another implementation of this embodiment, a third driving range is determined based on the first driving range and the second driving range, and a third prompt message corresponding to the third driving range is output. Specifically, the sum of the first driving range and the second driving range can be used as the third driving range.

[0122] Among these features, user-defined parameters can be retrieved, and the system can select one of the two methods mentioned above to provide a notification regarding the remaining battery life based on these parameters.

[0123] In this embodiment, by taking the above steps, in addition to increasing the target hydrogen consumption per unit mileage, it is beneficial to further improve the accuracy of the driving range, ensuring that users can perform timely vehicle maintenance based on the output prompts, thereby improving the vehicle's driving range.

[0124] Furthermore, in this embodiment, before the step of determining the second driving range of the vehicle based on the remaining power of the power battery system and the power consumption per unit mile, the method further includes: before the step of determining the second driving range of the vehicle based on the remaining power of the power battery system and the power consumption per unit mile, the method further includes: obtaining the output mode of the vehicle's driving range; when the output mode is a standard mode, determining the first driving range of the vehicle based on the standard hydrogen consumption per unit mile and the available hydrogen quantity of the hydrogen fuel cell system; when the output mode is an adaptive mode, determining the first driving range of the vehicle based on the target hydrogen consumption per unit mile and the available hydrogen quantity of the hydrogen fuel cell system.

[0125] Here, the user can input the setting parameters according to their own usage needs, and the output mode can be determined based on the setting parameters.

[0126] The standard unit mile hydrogen consumption data is obtained from experiments under certain preset operating conditions. These preset operating conditions can be industry-standard test conditions for hydrogen consumption per 100 kilometers, such as WLTC, or manufacturer-defined test conditions.

[0127] The first driving range, determined based on standard hydrogen consumption per unit mileage and available hydrogen, represents the longest distance a vehicle can travel under optimal conditions with the remaining hydrogen.

[0128] In this embodiment, the above method can be used to adapt to different user needs and output the driving range so that the output of the prompt information can accurately meet the user's driving range needs.

[0129] Furthermore, based on any of the above embodiments, another optional embodiment of the vehicle information determination method of this application is proposed. In this embodiment, the vehicle information determination method further includes:

[0130] Obtain the power supply mode of the vehicle;

[0131] When the power supply mode is a preset mode, the hydrogen consumption per unit mileage detected when the vehicle switches to the preset mode is determined as the target hydrogen consumption per unit mileage; wherein, in the preset mode, the power battery system is used alone for power supply.

[0132] When the power supply mode is a mode other than the preset mode, the steps of obtaining the vehicle's driving mileage during the target time period, the change in the remaining charge of the vehicle's power battery system during the target time period, and the hydrogen consumption of the vehicle's hydrogen fuel cell system during the target time period are executed.

[0133] Other modes here include modes that use a hydrogen fuel cell system alone to power the vehicle, and / or modes that use a hydrogen fuel cell system to charge the battery system and power the vehicle, and / or modes that use both the hydrogen fuel cell system and the battery system to power the vehicle, etc.

[0134] In this embodiment, the hydrogen fuel cell system is not activated in the preset mode, and the hydrogen consumption per unit mileage when entering the preset mode is used as the target mileage hydrogen consumption. In other modes besides the preset mode, the hydrogen fuel cell system is activated, and the target mileage hydrogen consumption is determined by combining the driving mileage, remaining charge change, and hydrogen consumption within the target time period, as described in the above embodiment. Based on this, accurate hydrogen consumption per unit mileage can be obtained regardless of whether the vehicle is powered by the hydrogen fuel cell system, improving the accuracy of vehicle performance evaluation using hydrogen consumption per unit mileage.

[0135] Furthermore, this embodiment of the invention also proposes a storage medium storing a vehicle information determination program, which, when executed by a processor, implements the relevant steps of any embodiment of the vehicle information determination method described above.

[0136] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or system that includes that element.

[0138] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods of the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
