[0066] The vehicle provided by the present application adopts the method for determining the cruising range in the following embodiments, which can solve the technical problem of how to improve the accuracy of the remaining mileage determined by a hydrogen energy vehicle. Compared with the prior art, the beneficial effects of the vehicle provided by the present application are the same as the beneficial effects of the method for determining the cruising range provided in the following embodiments, and the other technical features in the vehicle are the same as the features disclosed in the following embodiment methods, which will not be described in detail here.

[0067] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a vehicle, etc. capable of realizing the above functions. The following takes a vehicle as an example to illustrate this embodiment and the following embodiments.

[0068] Based on this, the present application embodiment provides a method for determining the cruising range, referring to Figure 2 , Figure 2 This is a flow chart of the first embodiment of the method for determining the cruising range of the present application.

[0069] In this embodiment, the method for determining the cruising range includes steps S10 to S30:

[0070] Step S10, monitoring the speed of the vehicle and obtaining the hydrogen consumption of the hydrogen energy device of the vehicle in a driving state and the mileage of the vehicle according to the monitored speed;

[0071] When the vehicle is powered on, the speed of the vehicle can be detected in real time and at set intervals. In this embodiment, the speed of the vehicle can be obtained by monitoring the operating parameters of the drive system on the vehicle, or can also be determined based on data monitored by a navigator.

[0072] Determine whether the vehicle is in a driving state based on the monitored vehicle speed, and obtain the hydrogen consumption of the hydrogen energy device and the vehicle's mileage when the vehicle is in a driving state; when the vehicle is not in a driving state, stop detecting the hydrogen consumption and mileage, or the data detected in this state is not used to determine the remaining mileage. In the process of determining whether the vehicle is in a driving state, it can be determined based on the current vehicle speed and / or the vehicle speed before the current vehicle speed. For example, the direction of speed change can be determined based on the current vehicle speed and the vehicle speed before the current moment, and whether the vehicle is in a driving state can be determined based on the direction of speed change and the current vehicle speed.

[0073] In this embodiment, the driving state refers to a continuous driving condition of the vehicle. In other embodiments, the driving state may also include more than one discontinuous driving condition of the vehicle (the vehicle may be in a non-driving state between two adjacent driving conditions). The non-driving state may include a parking state of the vehicle or a power-off state of the vehicle.

[0074] The hydrogen consumption here refers to the total amount of hydrogen consumed by the hydrogen energy device during driving. It can be determined based on the remaining hydrogen amount of the hydrogen energy device at the start time of the driving state and the remaining hydrogen amount of the hydrogen energy device at the end time of the driving state, or it can be determined based on the amount of hydrogen discharged from the outlet of the hydrogen energy device detected during driving.

[0075] The mileage here refers to the total mileage traveled by the hydrogen energy device in the driving state, which can be determined based on the first mileage accumulated by the odometer in the vehicle at the start time of the driving state and the second mileage accumulated by the odometer in the vehicle at the end time of the driving state, or it can be calculated based on the integral value of the speed of the vehicle that changes with time in the driving state.

[0076] Step S20, determining the hydrogen consumption per unit mileage of the vehicle according to the hydrogen consumption and the driving mileage;

[0077] Hydrogen consumption per unit mileage refers to the amount of hydrogen consumed by the hydrogen energy device when the vehicle travels a unit mileage.

[0078] When there are at least two hydrogen consumptions and corresponding mileages corresponding to the driving state, the hydrogen consumption and the corresponding mileage are one respectively, and the ratio of the hydrogen consumption to the mileage can be used as the hydrogen consumption per unit mileage.

[0079] When there are at least two hydrogen consumptions and at least two driving mileages corresponding to at least two driving states, the hydrogen consumption per unit mileage may be determined according to more than one hydrogen consumption and the corresponding driving mileages.

[0080] Step S30, determining the remaining mileage of the vehicle according to the current remaining hydrogen amount of the hydrogen energy device and the hydrogen consumption per unit mileage.

[0081] The cruising range is the distance the vehicle can travel based on the amount of hydrogen currently remaining in the hydrogen energy device.

[0082] The current remaining amount of hydrogen can be determined based on the current temperature and pressure of the hydrogen energy device, and can also be determined based on the flow rate detected by a flow meter corresponding to the hydrogen energy device.

[0083] In this embodiment, the ratio of the remaining hydrogen amount to the hydrogen consumption per unit mileage is taken as the remaining mileage.

[0084] This embodiment provides a method for determining a cruising range, which obtains the hydrogen consumption of a hydrogen energy device of the vehicle in a driving state and the mileage based on the monitored vehicle speed to calculate the hydrogen consumption per mileage of the vehicle, and then determines the remaining mileage of the vehicle by using the hydrogen consumption per mileage and the remaining hydrogen amount. The calculation of the hydrogen consumption per mileage is no longer based on data detected by a specified mileage or time, thereby ensuring that only the hydrogen consumption and mileage of the vehicle in a driving state are used to determine the remaining mileage, and relevant data when the vehicle is not in a driving state will not be used to determine the remaining mileage, so that the acquisition of the data related to the remaining mileage and the determination of the remaining mileage can adapt to the dynamic changes in the actual driving needs of the vehicle, thereby facilitating the improvement of the accuracy of the remaining mileage determined by hydrogen energy.

[0085] In one possible implementation, refer to Figure 3 The step of monitoring the vehicle speed and obtaining the hydrogen consumption of the hydrogen energy device of the vehicle in the driving state and the mileage of the vehicle according to the monitored vehicle speed includes:

[0086] Step S11, when it is monitored that the vehicle speed increases to a first preset vehicle speed, detecting a first remaining hydrogen amount of a hydrogen energy device in the vehicle and a first accumulated mileage of the vehicle;

[0087] The current speed of the vehicle is obtained in real time or at intervals of a set duration. When the monitored speed increases continuously and reaches the first preset speed or when the speed is maintained at a time greater than or equal to the first preset speed after the monitored speed increases continuously and reaches the first preset speed, the time can be determined as the first time, the remaining amount of hydrogen in the hydrogen energy device at the first time is obtained as the first remaining amount of hydrogen, and the mileage accumulated by the odometer of the vehicle at the first time is obtained as the first accumulated mileage. The first time here can be considered as the starting time when the vehicle starts to travel.

[0088] Step S12, when the vehicle speed reaches the first preset speed and then is monitored to decrease to a second preset speed, detecting a second remaining hydrogen amount of the hydrogen energy device in the vehicle and a second accumulated mileage of the vehicle;

[0089] The second preset vehicle speed may be less than or equal to the first preset vehicle speed. In this embodiment, the first preset vehicle speed and the second preset vehicle speed are both preset fixed parameters.

[0090] After step S11, the current speed of the vehicle is continuously acquired in real time or after a set detection time. During this process, the speed of the vehicle may increase or decrease. When the speed is detected to decrease and reach the second preset speed or when the speed is detected to decrease and reach the second preset speed and then the speed is maintained less than or equal to the second preset speed for a second time, the moment may be determined as the second moment, the remaining amount of hydrogen in the hydrogen energy device at the second moment may be acquired as the second remaining amount of hydrogen, and the accumulated mileage of the odometer of the vehicle at the second moment may be acquired as the second accumulated mileage. The second moment here may be considered as the end moment of the vehicle ending the driving state.

[0091] Step S13: determining the hydrogen consumption according to a first difference between the first remaining hydrogen amount and the second remaining hydrogen amount, and determining the driving mileage according to a second difference between the second accumulated mileage and the first accumulated mileage.

[0092] In this embodiment, the first difference is used as the hydrogen consumption of the vehicle in the driving state, and the second difference is used as the mileage of the vehicle in the driving state.

[0093] In this embodiment, through the above-mentioned method, relevant data can be accurately collected at the start and end times of the driving state based on the vehicle speed, which is beneficial to further improve the accuracy of the determined remaining mileage.

[0094] In other embodiments, the hydrogen consumption of the vehicle in the driving state may be obtained by correcting the first difference according to the first correction value, and the mileage of the vehicle in the driving state may be obtained by correcting the second difference according to the second correction value. The first correction value and the second correction value may be pre-set fixed values, or may be determined according to the actual driving conditions of the vehicle in the driving state. For example, the first correction value and the second correction value may be determined according to the difference between the maximum speed and the minimum speed of the vehicle in the driving state and the time difference between the first moment and the second moment.

[0095] In other embodiments, the first preset vehicle speed and the second preset vehicle speed may also be determined based on the road conditions of the current road on which the vehicle is located, for example, the first preset vehicle speed and the second preset vehicle speed may be determined based on the slope of the current road on which the vehicle is located, etc.

[0096] Based on any of the above embodiments, in the second embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 4 , before step S20 and after step S12, further comprising:

[0097] Step S101, determining whether a first preset condition is met; wherein the first preset condition indicates that the remaining amount of hydrogen in the hydrogen energy device detected is valid;

[0098] If the first preset condition is met, step S13 is executed; if the first preset condition is not met, step S14 is executed;

[0099] In this embodiment, the first preset condition includes at least one of the following:

[0100] The first remaining hydrogen amount is greater than or equal to the second remaining hydrogen amount;

[0101] There is no fault in the detection module corresponding to the remaining hydrogen amount of the hydrogen energy device.

[0102] Step S13, determining the hydrogen consumption according to a first difference between the first remaining hydrogen amount and the second remaining hydrogen amount, and determining the driving mileage according to a second difference between the second accumulated mileage and the first accumulated mileage;

[0103] Step S14, determining the hydrogen consumption according to the power generation state parameters of the fuel-electric system connected to the hydrogen energy device in the driving state.

[0104] The power generation state parameters may include at least one of the following: fuel-fired power generation value, fuel-fired water temperature, total voltage of fuel cell stack, etc.

[0105] A correspondence between power generation state parameters and hydrogen consumption is established in advance. The correspondence may include a relational expression, a mapping table, etc. Based on the correspondence, the hydrogen consumption corresponding to the current power generation state parameters may be determined.

[0106] In this embodiment, the hydrogen consumption rate of the fuel-electric system is determined based on the fuel-electric power generation power value, the fuel-electric water temperature and the total voltage of the fuel cell stack, and the hydrogen consumption is determined based on the product of the hydrogen consumption rate and the total time in the driving state (the interval between the first moment and the second moment mentioned above).

[0107] In this embodiment, when the remaining hydrogen amount detection is valid, the hydrogen consumption of the vehicle in the driving state is calculated based on the first remaining hydrogen amount and the second remaining hydrogen amount obtained by the vehicle speed detection. When the remaining hydrogen amount detection fails, the hydrogen consumption of the vehicle in the driving state is indirectly calculated based on the power generation state parameters of the fuel-electric system, which is beneficial to further improve the accuracy of the remaining mileage determined by hydrogen energy vehicles.

[0108] In other embodiments, the first preset condition includes that the first remaining hydrogen amount is less than or equal to the preset hydrogen amount and / or the second remaining hydrogen amount is less than or equal to the preset hydrogen amount. Alternatively, the first preset condition includes receiving a failure instruction for the remaining hydrogen amount detection.

[0109] Based on any of the above embodiments, in the second embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 3 The step of determining the hydrogen consumption per unit mileage of the vehicle according to the hydrogen consumption and the driving mileage comprises:

[0110] Step S21, when there are at least two hydrogen consumptions and at least two driving mileages corresponding to at least two driving states, determining the sub-unit mileage hydrogen consumption in the corresponding driving state according to the hydrogen consumption and the corresponding driving mileage;

[0111] In this embodiment, the driving state refers to a continuous driving condition of the vehicle.

[0112] In the process of continuously monitoring the vehicle speed from the start time to the current time, if more than one driving state occurs based on the vehicle speed monitoring, a hydrogen consumption and a driving mileage are obtained for each driving state. The start time here can be a time specified by the user, or the time when the hydrogen energy device was last refueled, or a time with a preset time interval from the current time, etc. Among them, the vehicle can be in a power-off state or a parking state between two adjacent driving states.

[0113] Each driving state can determine a sub-unit mileage hydrogen consumption according to the corresponding hydrogen consumption and the driving mileage. The ratio of the hydrogen consumption and the corresponding driving mileage can be used as the sub-unit mileage hydrogen consumption in the corresponding driving state.

[0114] Step S22: determining the hydrogen consumption per unit mileage according to at least two of the sub-hydrogen consumption per unit mileage.

[0115] In this embodiment, the hydrogen consumption per unit mileage is determined according to the average value of at least two sub-unit mileage hydrogen consumptions. The average value of at least two sub-unit mileage hydrogen consumptions is determined; the weighting coefficient of each sub-unit mileage hydrogen consumption is determined according to the deviation value between each sub-unit mileage hydrogen consumption and the average value, and each weighting coefficient conforms to the normal distribution; the hydrogen consumption per unit mileage is determined according to at least two sub-unit mileage hydrogen consumptions and the corresponding weighting coefficients. Each sub-unit mileage hydrogen consumption corresponds to a weighting coefficient, and the hydrogen consumption per unit mileage can be obtained by weighted averaging the at least two sub-unit mileage hydrogen consumptions based on at least two weighting coefficients.

[0116] In this embodiment, the above-mentioned method is helpful to reduce the remaining mileage calculation deviation caused by the fluctuation of the vehicle driving condition, and is helpful to further improve the accuracy of the determined remaining mileage.

[0117] In other embodiments, the average value may be used as the hydrogen consumption per unit mileage, or the maximum value or the minimum value of at least two sub-hydrogen consumption per unit mileage may be used as the hydrogen consumption per unit mileage.

[0118] In other embodiments, when there are at least two of the hydrogen consumptions and at least two of the mileages corresponding to at least two of the driving states, the total hydrogen consumption can also be determined based on more than one hydrogen consumption, and the total mileage can be determined based on more than one mileage, and the ratio of the total hydrogen consumption to the total mileage is used as the hydrogen consumption per unit mileage.

[0119] In a feasible implementation manner, when there are at least two hydrogen consumptions and at least two mileages corresponding to at least two driving states, the step of determining the sub-unit mileage hydrogen consumption in the corresponding driving state according to the hydrogen consumption and the corresponding mileage includes: when there are at least two hydrogen consumptions and at least two mileages corresponding to at least two driving states, determining the mileage greater than or equal to the preset mileage as the effective mileage, and determining the effective sub-unit mileage hydrogen consumption according to the effective mileage and the corresponding hydrogen consumption; the step of determining the unit mileage hydrogen consumption according to at least two sub-unit mileage hydrogen consumptions includes: determining the unit mileage hydrogen consumption according to all the effective sub-unit mileage hydrogen consumptions.

[0120] That is to say, the driving mileage less than the preset mileage and its corresponding hydrogen consumption are not involved in the determination of the remaining mileage.

[0121] When the number of effective sub-unit mileage hydrogen consumption is one, the effective sub-unit mileage hydrogen consumption is determined as the unit mileage hydrogen consumption.

[0122] When the number of effective sub-unit mileage hydrogen consumption is more than one, the unit mileage hydrogen consumption is determined according to the average value of at least two effective sub-unit mileage hydrogen consumptions. The average value of all sub-unit mileage hydrogen consumptions is determined, and the weighting coefficient of each effective sub-unit mileage hydrogen consumption is determined according to the deviation value between each effective sub-unit mileage hydrogen consumption and the average value, wherein each weighting coefficient conforms to the normal distribution; the unit mileage hydrogen consumption is determined according to at least two effective sub-unit mileage hydrogen consumptions and the corresponding weighting coefficients. Each effective sub-unit mileage hydrogen consumption corresponds to a weighting coefficient, and the unit mileage hydrogen consumption can be obtained by weighted averaging the at least two effective sub-unit mileage hydrogen consumptions based on at least two weighting coefficients.

[0123] In this embodiment, the above method is helpful to further improve the accuracy of the determined remaining mileage.

[0124] In order to better understand the solution of this embodiment, Figure 5 This is a schematic diagram of the vehicle speed changing over time within a period of time, combined with Figure 5 The process of determining the cruising range is explained below:

[0125] The starting time of each driving state is the time when the vehicle speed is monitored to increase to a first preset speed or the time when the vehicle speed increases to the first preset speed and lasts for a first time. The ending time of each driving state is the time when the vehicle speed is monitored to decrease to a second preset speed after reaching or exceeding the first preset speed or the time when the vehicle speed decreases to the second preset speed and lasts for a second time. The corresponding remaining hydrogen amount and cumulative mileage are detected at the starting time and the ending time of each driving state respectively. The difference between the remaining hydrogen amount at the starting time and the remaining hydrogen amount at the ending time is the first hydrogen consumption of the corresponding driving state. The difference between the cumulative mileage at the ending time and the cumulative mileage at the starting time is the driving mileage of the corresponding driving state. The power generation state parameters of the fuel-electric system in the driving state can determine the corresponding second hydrogen consumption. Based on this, if driving state 1 meets the first preset condition, the first sub-unit mileage hydrogen consumption corresponding to driving state 1 is determined according to the ratio of the first hydrogen consumption to the mileage; if driving states 2 and 4 do not meet the first preset condition, the second sub-unit mileage hydrogen consumption of driving state 2 and the fourth sub-unit mileage hydrogen consumption of driving state 4 are correspondingly determined according to the ratio of the second hydrogen consumption to the mileage; wherein, if driving states 1, 2, and 4 all meet the second preset condition, the first sub-unit mileage hydrogen consumption, the second sub-unit mileage hydrogen consumption, and the fourth sub-unit mileage hydrogen consumption are used to determine the unit mileage hydrogen consumption, and if driving state 3 does not meet the second preset condition, the corresponding sub-unit mileage hydrogen consumption does not participate in determining the unit mileage hydrogen consumption, then the unit mileage hydrogen consumption = first sub-unit mileage hydrogen consumption * weighting coefficient 1 + second sub-unit mileage hydrogen consumption * weighting coefficient 2 + fourth sub-unit mileage hydrogen consumption * weighting coefficient 4, and weighting coefficient 1, weighting coefficient 2, and weighting coefficient 4 conform to the normal distribution.
