[0076] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0077] The driving range prediction method provided in this application can be applied to, for example... Figure 1The application environment shown includes a target vehicle 101 and a server 102, which can communicate via network. Upon receiving the current remaining hydrogen fuel and current remaining electricity from the target vehicle, the server determines the current usage status of the target vehicle, obtains its historical driving data, and determines the predicted driving range under multiple energy consumption states based on the historical driving data. The server then integrates the predicted driving range under multiple energy consumption states to obtain the total predicted driving range of the target vehicle, which can then be sent to the target vehicle for display. The target vehicle 101 can be, but is not limited to, any vehicle with network communication capabilities; further, the target vehicle 101 can be a hydrogen fuel cell vehicle. The server 102 can be a standalone server or a server cluster consisting of multiple servers; further, the server 102 can be a cloud server, i.e., a server used to implement a cloud platform.

[0078] In one embodiment, such as Figure 2 As shown, a method for predicting driving range is provided, which is then applied to... Figure 1 Taking the server in the example, the following steps are included:

[0079] S201, determine the current usage status of the target vehicle based on the current remaining hydrogen fuel and the current remaining electrical charge.

[0080] The current usage status refers to the target vehicle's current energy consumption status, specifically whether the target vehicle is currently in a standard usage state. This can be further divided into three usage states: standard usage state, high hydrogen consumption usage state, and high electricity consumption usage state. A high hydrogen consumption usage state indicates that the target vehicle's hydrogen consumption has exceeded its electricity consumption during historical driving, while a high electricity consumption usage state indicates that the target vehicle's electricity consumption has exceeded its hydrogen consumption during historical driving.

[0081] In hydrogen fuel cell vehicles, due to the long response time and lack of energy recovery characteristics of hydrogen fuel cells, they are often used in conjunction with energy storage systems such as batteries. This step involves simultaneously acquiring the current remaining hydrogen fuel level and the current remaining battery charge of the target vehicle, and then determining the current usage status of the target vehicle based on this information.

[0082] Optionally, the server can receive real-time vehicle operation data uploaded by the target vehicle, determine the current remaining hydrogen fuel and current remaining electricity based on the vehicle operation data, and determine the current usage status of the target vehicle based on the current remaining hydrogen fuel and current remaining electricity.

[0083] S202, acquire the historical driving data of the target vehicle, and determine the predicted driving range of the current usage state under multiple energy consumption states based on the historical driving data.

[0084] Among them, historical driving data refers to the driving data of the target vehicle in the historical time period before the current moment, which may include the running time, energy consumption, energy replenishment, remaining hydrogen fuel, and remaining electricity of the target vehicle under various energy consumption states in the historical time period.

[0085] Optionally, after obtaining historical driving data, data cleaning can be performed on the historical driving data, which mainly includes erroneous frame deletion, missing data filling, missing frame identification, and mileage jump identification.

[0086] Energy consumption states can refer to different energy consumption or replenishment states of the target vehicle, including: pure hydrogen energy consumption state A, pure electric energy consumption state B, hydrogen and electric combined energy consumption state C, hydrogen replenishment state D, hydrogen energy consumption and replenishment state E, deceleration replenishment state F, and battery charging state G. The following is based on the hydrogen fuel cell current I. fc >0, battery current I bat =0, vehicle speed V, explain these energy consumption states respectively:

[0087] Pure hydrogen energy consumption state A: Only hydrogen fuel provides kinetic energy to the target vehicle. In this case, the hydrogen fuel cell current I... fc >0, battery current I bat =0.

[0088] Pure electric energy consumption state B: Only the battery (i.e., the power battery) provides kinetic energy to the target vehicle. In this case, the hydrogen fuel cell current I... fc =0, battery current I bat >0.

[0089] Hydrogen and electricity co-consumption state C: Hydrogen fuel and battery jointly provide kinetic energy to the target vehicle. In this case, the hydrogen fuel cell current I... fc >0, battery current I bat >0.

[0090] Hydrogen recharging state D: Hydrogen fuel only recharges the battery. In this state, the hydrogen fuel cell current I... fc >0, battery current I bat <0, vehicle speed V=0.

[0091] Hydrogen-fueled energy replenishment state E: Hydrogen fuel provides kinetic energy to the target vehicle and replenishes the battery with excess energy. At this time, the hydrogen fuel cell current I... fc >0, battery current I bat <0, vehicle speed V>0.

[0092] Deceleration and Recharge State F: During deceleration and recharge state, when the vehicle decelerates, a regenerative current is generated to recharge the battery. At this time, the hydrogen fuel cell current I... fc =0, battery current I bat <0, vehicle speed V≥0, there is a brake pedal press signal.

[0093] Battery charging state G: The charging station is charging the battery. At this time, the hydrogen fuel cell current I... fc =0, battery current I bat <0, vehicle speed V=0, no brake pedal input signal, hydrogen fuel does not charge the battery.

[0094] Optionally, the process of determining the predicted driving range under multiple energy consumption states can be as follows: based on historical driving data, determine the driving range information of the target vehicle under each energy consumption state in a historical time period, and obtain the corresponding predicted driving range value based on the driving range information.

[0095] S203, the total range prediction value of the target vehicle is obtained by integrating the range prediction values ​​under the multiple energy consumption states.

[0096] The target vehicle will experience various energy consumption states during actual use. Therefore, by determining the predicted driving range under each energy consumption state and integrating these predicted driving range values, the total predicted driving range of the target vehicle during the entire use process can be obtained.

[0097] Optionally, the predicted driving range can be integrated by summing, weighted summing, or other methods.

[0098] The aforementioned range prediction method determines the current usage status of the target vehicle based on its current remaining hydrogen fuel and battery charge. It acquires historical driving data and, based on this data, determines the predicted range under multiple energy consumption states, achieving a detailed assessment of different energy consumption states. The total predicted range of the target vehicle is obtained by integrating these predicted range values ​​from multiple energy consumption states. By subdividing the energy consumption states of the fuel cell vehicle and predicting the mileage under different states separately, the accuracy of range prediction is greatly improved. Furthermore, by further subdividing the fuel cell vehicle's energy consumption states and predicting the mileage under different states, the accuracy of range prediction is significantly enhanced. This avoids problems such as vehicle breakdowns due to inaccurate range prediction, preventing timely refueling of the fuel cell vehicle and improving the end-user experience.

[0099] In one optional embodiment, determining the predicted driving range of the current usage state under multiple energy consumption states based on the historical driving data includes: filtering driving data under the multiple energy consumption states from the historical driving data and integrating them to obtain state driving data under each energy consumption state; determining at least one of the unit mileage energy consumption and state energy consumption ratio under the multiple energy consumption states based on the state driving data; wherein the state energy consumption ratio is the ratio of energy consumption under any energy consumption state to associated energy consumption, and the associated energy consumption is the total energy consumption associated with the energy source type of any energy consumption state; and determining the predicted driving range of the current usage state under multiple energy consumption states based on at least one of the unit mileage energy consumption and the state energy consumption ratio.

[0100] The process of filtering driving data under various energy consumption states from historical driving data and integrating it to obtain state driving data under each energy consumption state can be as follows: filtering driving data under various pure hydrogen energy consumption states from historical driving data and integrating it to obtain state driving data under pure hydrogen energy consumption states; filtering driving data under various pure electric energy consumption states from historical driving data and integrating it to obtain state driving data under pure electric energy consumption states; filtering driving data under various hydrogen-electric combined energy consumption states from historical driving data and integrating it to obtain state driving data under hydrogen-electric combined energy consumption states; filtering driving data under various hydrogen recharging states from historical driving data and integrating it to obtain state driving data under hydrogen recharging states; filtering driving data under various hydrogen energy consumption and recharging states from historical driving data and integrating it to obtain state driving data under hydrogen energy consumption and recharging states; filtering driving data under various deceleration recharging states from historical driving data and integrating it to obtain state driving data under deceleration recharging states; and filtering driving data under various battery charging states from historical driving data and integrating it to obtain state driving data under battery charging states.

[0101] When the energy consumption state is either pure hydrogen energy consumption state, hydrogen-electric combined energy consumption state, hydrogen-electric supplementary energy consumption state, or hydrogen energy consumption-electric supplementary energy consumption state, the corresponding associated energy consumption is the same: the sum of the hydrogen fuel consumption in each of these states, resulting in the total hydrogen fuel consumption. When calculating the energy consumption percentage for each state, the energy consumption in the corresponding state is divided by the associated energy consumption.

[0102] The above embodiments filter state driving data for each energy consumption state from historical driving data, determine the energy consumption per unit mile and the state energy consumption ratio for the corresponding energy consumption state based on the state driving data, and determine the predicted driving range for the corresponding energy consumption state based on at least one of the energy consumption per unit mile and the state energy consumption ratio. This achieves accurate prediction of the driving range for each subdivided energy consumption state, and can further obtain an accurate predicted total driving range.

[0103] In an optional embodiment, for pure hydrogen energy consumption state A, determining at least one of the unit mileage energy consumption and state energy consumption ratio based on the state driving data includes: obtaining the pure hydrogen fuel energy consumption and pure hydrogen energy consumption driving mileage in the pure hydrogen energy consumption state; obtaining the unit mileage energy consumption in the pure hydrogen energy consumption state based on the ratio of the pure hydrogen fuel energy consumption and the pure hydrogen energy consumption driving mileage; obtaining the total energy consumption associated with hydrogen fuel consumption to obtain the total hydrogen fuel consumption; and obtaining the state energy consumption ratio in the pure hydrogen energy consumption state based on the ratio of the pure hydrogen fuel energy consumption and the total hydrogen fuel consumption. It should be noted that hydrogen fuel energy consumption can also be simply referred to as hydrogen energy consumption.

[0104] Optionally, the total energy consumption associated with hydrogen fuel consumption is obtained to obtain the total hydrogen fuel consumption Q. fc总 Q fc +Q fc+bat +Q fcTobatD1 +Q fcTobatD2 Among them, Q fc Q represents the energy consumption of hydrogen when a pure hydrogen fuel cell powers the target vehicle. fc+bat Q represents the energy consumed by hydrogen when hydrogen and electricity work together to provide kinetic energy to the target vehicle. fcTobatD1 Q represents the energy consumed by hydrogen fuel when it is used only to charge the battery. fcTobatD2 This refers to the energy consumed when hydrogen fuel provides kinetic energy to the target vehicle and replenishes the power battery with excess energy.

[0105] Optionally, the formula for calculating the energy consumption per unit mile (kWh / km) in pure hydrogen energy consumption state A is as follows:

[0106] EC_A = Q fc / S fc , among which, S fc This indicates the driving range using pure hydrogen, that is, the driving range of the target vehicle when pure hydrogen fuel provides kinetic energy.

[0107] The formula for calculating the energy consumption percentage of pure hydrogen in state A is as follows:

[0108] EC_AR = Q fc / (Q fc +Q fc+bat +Q fcTobatD1 +Q fcTobatD2 ).

[0109] The above embodiments calculate the unit mileage energy consumption and state energy consumption ratio under pure hydrogen energy consumption state A based on the driving mileage under hydrogen energy consumption and hydrogen supply states. This fully considers various factors related to hydrogen energy consumption, making the calculated hydrogen energy consumption driving parameters more accurate and ensuring the accuracy of driving range prediction.

[0110] In an optional embodiment, for pure electric energy consumption state B, determining at least one of the unit mileage energy consumption and state energy consumption ratio in the plurality of energy consumption states based on the state driving data includes: obtaining the pure electric energy consumption and the pure electric driving mileage in the pure electric energy consumption state; and obtaining the unit mileage energy consumption in the pure electric energy consumption state based on the ratio of the pure electric energy consumption and the pure electric driving mileage.

[0111] Optionally, the total power consumption associated with power consumption can be obtained, and the state energy consumption ratio under the pure power consumption state can be obtained based on the ratio of the pure power consumption energy to the total power consumption.

[0112] The formula for calculating energy consumption per unit mileage in pure electric energy consumption state B is as follows:

[0113] EC_B = Q bat / S bat , where Q bat S represents the energy consumed in pure electricity. bat This indicates the driving range using pure electric power, that is, the driving range under pure electric power consumption conditions.

[0114] The formula for calculating the energy consumption ratio of pure electric energy consumption state B is as follows:

[0115] EC_BR=Q bat / (Q bat +Q bat+fc ), where Q bat+fc Q is the energy consumed by the battery when hydrogen and electricity jointly provide power to the target vehicle. bat +Q bat+fc This indicates the total power consumption.

[0116] The above embodiments calculate the unit mileage energy consumption and state energy consumption ratio under pure electric energy consumption state B based on power consumption and driving mileage under electric power supply state. This fully considers various factors related to power consumption, making the calculated power consumption driving parameters more accurate and ensuring the accuracy of driving range prediction.

[0117] In an optional embodiment, for a hydrogen-electric co-energy consumption state C, determining at least one of the unit mileage energy consumption and state energy consumption ratio in the plurality of energy consumption states based on the state driving data includes: obtaining the hydrogen fuel sub-energy consumption and the hydrogen-electric co-energy consumption driving mileage in the hydrogen-electric co-energy consumption state; obtaining the unit mileage energy consumption in the hydrogen-electric co-energy consumption state based on the ratio of the hydrogen fuel sub-energy consumption and the hydrogen-electric co-energy consumption driving mileage; and obtaining the state energy consumption ratio in the hydrogen-electric co-energy consumption state based on the ratio of the hydrogen fuel sub-energy consumption and the total hydrogen fuel consumption.

[0118] The formula for calculating the energy consumption per unit mile in hydrogen-electric co-energy consumption state C is as follows:

[0119] EC_Cfc=Q fc+bat / S fc+bat , where Q fc+bat S represents the energy consumed by hydrogen fuel under the combined hydrogen and electricity consumption state. fc+bat This indicates the driving range when hydrogen and electricity are used together, that is, the driving range under the condition of using hydrogen and electricity together.

[0120] The formula for calculating the energy consumption ratio of state C, where hydrogen and electricity co-consume energy, is as follows:

[0121] EC_CRfc = Q fc+bat / (Q fc +Q fc+bat +Q fcTobatD1 +Q fcTobatD2 ).

[0122] Optionally, in hydrogen-electric co-energy consumption state C, hydrogen fuel and battery jointly power the target vehicle. The relevant parameters can be calculated based on hydrogen consumption (as described above) or electricity consumption, as follows:

[0123] The formula for calculating the energy consumption per unit mile in hydrogen-electric co-energy consumption state C is as follows:

[0266] The above embodiments, based on the actual energy consumption of the vehicle, acquire various driving data of the target vehicle in a benchmark range that is closer to the current energy consumption state of the vehicle. The acquired driving data is as close as possible to the current energy consumption state of the vehicle, which can effectively ensure the accuracy of the predicted driving range.

[0267] In one optional embodiment, obtaining the historical driving data of the target vehicle includes: obtaining the vehicle identification code uploaded by the target vehicle in real time; and obtaining the historical driving data of the target vehicle from the historical driving database based on the vehicle identification code.

[0275] 4. The cloud determines the predicted driving range under various energy consumption conditions based on the vehicle's historical driving data and obtains the predicted total driving range. Then, the cloud sends the predicted total driving range to the target vehicle.

[0276] In the above embodiments, through real-time coordination between the vehicle, cloud, and database, the total driving range of the target vehicle can be accurately predicted based on its current state and historical driving data, achieving accurate range prediction. By combining the current state of the fuel cell vehicle with the cloud platform's access to historical data, different energy consumption states can be identified, and the predicted driving range under different energy consumption states can be calculated more accurately.

[0279] In the above embodiments, the vehicle, cloud, and database work together to accurately predict the vehicle's driving range and ultimately provide feedback to the vehicle user for reasonable scheduling of hydrogen and electric vehicle refueling. The vehicle's driving range is predicted based on real-time data uploaded by the vehicle from the big data platform and displayed on the vehicle, providing end-users with accurate references for timely refueling and hydrogen replenishment.
