[0056] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0057] To facilitate understanding of this application, the following explanations are provided for the terms used in this application:

[0058] Remaining charge (State of Charge, SOC): The percentage of usable charge in the battery relative to its nominal capacity.

[0059] State of Charge (SOC): The target value for vehicle battery balance. It represents the battery state that the owner expects the vehicle to achieve during driving. For daily driving, as long as the target SOC is set higher than the actual remaining SOC, the DM-i engine will continuously generate electricity to try to maintain the battery level at the target point, thereby extending the driving range.

[0060] Operating mode: The way a vehicle's power system manages and distributes energy under different operating conditions. For plug-in hybrid electric vehicles, the vehicle's operating mode is divided into pure electric mode (Electric Vehicle, EV) and hybrid mode (Hybrid Electric Vehicle, HEV).

[0061] Operating modes: The vehicle offers preset modes for different driving experiences. These modes adjust parameters such as the engine, electric motor, throttle response, steering assist, and stability control system to change the vehicle's performance. The main operating modes are: Eco mode, Normal mode, and Sport mode.

[0062] Power supply maintenance methods: Control strategies that maintain the State of Charge (SOC) of a vehicle near its equilibrium point. Depending on the objective and applicable scenario, these strategies are divided into intelligent power supply maintenance and forced power supply maintenance. The goal of intelligent power supply maintenance is energy saving. It utilizes advanced sensors and algorithms to monitor and adjust the operating status of equipment in real time to achieve efficient energy utilization. The goal of forced power supply maintenance is to ensure that electrical equipment can operate normally at all times. It uses mandatory measures to ensure that the power supply is above the SOC equilibrium point.

[0063] The application scenarios of the technical solution in this application will be introduced below, such as... Figure 1 The diagram shown is an application scenario illustration of a display method and an energy calculation method provided in an embodiment of this application. The embodiment of this application is applied to a vehicle.

[0064] Specifically, the vehicle is a hybrid electric vehicle, comprising a battery, an engine, and a generator. When the battery has a sufficient charge, the vehicle operates in pure electric mode, powered entirely by the battery. When the battery has a low charge, the vehicle operates in hybrid mode, where the engine drives the generator to produce electricity to power the vehicle. The electricity generated by the generator may also be used to charge the battery. Therefore, during this process, the battery may be in a charging state, a discharging state, or a state of simultaneous charging and discharging.

[0065] The vehicle comprises a processor, a central control system, and a battery management system. The processor, such as the Vehicle Control Unit (VCU), collects real-time information about the vehicle's operating status, including SOC (State of Charge), operating mode, current fuel level, and battery charging method. The Battery Management System (BMS) collects battery information, such as current battery charge. The central control system integrates a vehicle navigation application, enabling real-time interaction between cloud algorithms, the vehicle navigation system, and the vehicle's CAN bus signals. The system can obtain the vehicle's current operating information from the processor, central control system, and battery management system.

[0066] Vehicle operating information includes operational data and navigation data. Operational data may include current battery level, current fuel level, State of Charge (SOC) balance point, operating mode, initial battery level range, and SOC balance point range. The initial battery level range and SOC balance point range are generated using a K-means clustering algorithm. Current battery level corresponds to the battery level at the start of the trip, and current fuel level corresponds to the fuel level at the start of the trip. Navigation data may include mileage, trip time, and average speed. Of course, operational data may also include driving style, which can affect battery consumption. For the same distance traveled, a faster vehicle consumes more battery power. Driving style is determined based on historical acceleration and historical throttle input. Driving styles include aggressive, normal, and conservative. It can be understood that a higher historical acceleration and deeper historical throttle input indicate a more aggressive driving style. This allows for the inclusion of driving style as a factor in calculating total energy consumption, remaining battery power, and remaining fuel, making these calculations more accurate.

[0067] This application provides a display method, which will be described in detail below:

[0068] Please see Figure 2 This application provides a display method, which includes:

[0069] Step 01: Display energy information based on the navigation data of the vehicle's scheduled trip; the energy information includes at least the remaining battery power and fuel level when the vehicle ends the scheduled trip based on the navigation data.

[0070] Specifically, a screen can be installed in the vehicle to display driving-related information, allowing users to intuitively understand this information. Users can set a predetermined route before starting to drive, and the vehicle's navigation system can generate navigation data based on the predetermined route, such as the starting point of the route (e.g., the vehicle's navigation system). Figure 3 Point A in the diagram) and the target location (e.g., point A in the diagram) and the target location (e.g. Figure 3 Point B in the navigation system determines the estimated travel time, mileage, and route. The vehicle can calculate the remaining battery and fuel levels when it completes the planned trip based on the navigation data. For example, the remaining battery and fuel levels can be determined using the energy calculation method described below (this will not be elaborated here for simplicity), or other calculation methods can be used. The vehicle can then acquire and display energy information, which includes at least the remaining battery and fuel levels when it completes the planned trip based on the navigation data.

[0071] Thus, after determining the navigation data, energy information can be displayed on the vehicle's navigation screen. This energy information includes at least the remaining fuel and remaining battery power, for example... Figure 3 This information is displayed so that users can easily check it and thus schedule charging and refueling times accordingly based on the remaining battery and fuel levels.

[0072] The display method of this application can display energy information based on the navigation data of the vehicle's predetermined trip. The energy information includes at least the remaining battery power and fuel level when the vehicle ends the predetermined trip according to the navigation data. This allows the user to quickly determine the remaining battery power and fuel level based on the information displayed on the vehicle's screen, thereby facilitating the reasonable scheduling of charging and refueling based on the remaining battery power and fuel level.

[0073] In some implementations, energy information also includes electrical energy consumption and fuel energy consumption. Electrical energy consumption refers to the electrical energy consumed by the vehicle while traveling according to navigation data, and fuel energy consumption refers to the fuel consumption by the vehicle while traveling according to navigation data. When calculating remaining battery power and fuel level, the vehicle typically calculates the electrical energy consumption and fuel consumption during the travel process based on navigation data. In this case, electrical energy consumption can be determined based on the electrical energy consumption, and fuel energy consumption can be determined based on the fuel consumption. When displaying energy information, the vehicle can also display both electrical energy consumption and fuel energy consumption to allow the user to view the energy required to travel a predetermined distance.

[0074] In some implementations, energy information also includes the total energy consumption of the vehicle based on navigation data, which corresponds to electrical energy consumption and fuel energy consumption. Total energy consumption refers to the total energy used for driving during operation. Total energy consumption may correspond to the amount of electricity generated when the battery discharges, or it may correspond to the amount of electricity generated by the engine driving the generator, depending on the vehicle's operating mode and state. For example, in pure electric mode, total energy consumption corresponds to the amount of electricity generated when the battery discharges. In hybrid mode, total energy consumption may only correspond to the amount of electricity generated by the engine driving the generator, in which case the battery is not discharging; alternatively, total energy consumption may correspond to both the amount of electricity generated by the engine driving the generator and the amount of electricity generated when the battery discharges, in which case the battery is discharging. When calculating remaining battery power and remaining fuel, the vehicle can also calculate the total energy consumption during driving based on navigation data. Therefore, when displaying energy information, the vehicle can also display total energy consumption so that users can see the energy required to travel a predetermined distance.

[0075] Please see Figure 4 In some implementations, the display method further includes:

[0076] Step 02: Display navigation information, which is determined based on navigation data. The navigation information includes at least one of the following: departure location, destination location, estimated travel time, mileage, route, travel time, and average speed.

[0077] Specifically, please combine Figure 5The in-vehicle navigation function can generate navigation data based on the planned itinerary, such as the starting point of the planned itinerary (e.g., Figure 5 Point A in the diagram) and the target location (e.g., point A in the diagram) and the target location (e.g. Figure 5 The system uses point B in the map (the starting point) and the road conditions between the starting and destination points to determine at least one of the following: estimated travel time, mileage, route, travel duration, and average speed. Therefore, navigation information can also be displayed on the vehicle's screen. This navigation information is determined based on navigation data, ensuring that it includes at least one of the following: the starting point, destination, estimated travel time, mileage, route, travel duration, and average speed.

[0078] In this way, navigation information and energy information can be displayed on the screen at the same time, so that users can intuitively understand the navigation information and energy information, and thus make it easier for users to plan their trips better based on the navigation information and energy information.

[0079] Please see Figure 4 In some implementations, the display method further includes:

[0080] Step 03: Display historical driving style, which is determined based on historical driving data.

[0081] Specifically, historical driving styles can be categorized as aggressive, moderate, and conservative. Please combine... Figure 3 Driving style can also affect battery consumption; for the same distance, a faster vehicle consumes more battery power. Historical driving style is determined based on historical driving data, such as historical acceleration and historical throttle depth. It can be understood that the greater the historical acceleration and the deeper the historical throttle depth, the more aggressive the historical driving style.

[0082] Therefore, the vehicle can also predict the remaining battery power and fuel level by combining historical driving styles. At this time, the historical driving styles can be displayed on the vehicle's screen so that the user can determine which historical driving style the current prediction of the remaining battery power and fuel level is based on, thus making it easier for the user to better plan the driving trip by combining the historical driving styles.

[0083] Please see Figure 6 In some implementations, the display method further includes:

[0084] Step 04: In the first situation, display the charging station closest to the first driving position. The first situation is when the remaining battery power is less than the preset battery power threshold. The first driving position is the vehicle's position when the battery power drops to the preset battery power threshold.

[0085] Step 05: In the second situation, display the gas station closest to the second driving position. The second situation is when the remaining fuel is less than the preset fuel threshold. The second driving position is the vehicle's position when the fuel level drops to the preset fuel threshold.

[0086] Specifically, the preset battery level threshold ensures the minimum battery level required for normal vehicle use, for example, 25%. If the battery level falls below the preset threshold, the vehicle needs to be charged. Similarly, the preset fuel level threshold ensures the minimum fuel level required for normal vehicle use, for example, 25%. If the fuel level falls below the preset threshold, the vehicle needs to be refueled.

[0087] In the first scenario, where the calculated remaining battery power is less than a preset battery power threshold, the vehicle can calculate its first driving position when the battery power drops to the preset threshold and locate the nearest charging station based on map information. Therefore, in the first scenario, the nearest charging station can be displayed on the vehicle's screen to facilitate timely charging by the driver.

[0088] In the second scenario, where the calculated remaining fuel level is less than a preset fuel level threshold, the vehicle can calculate its second driving position when the fuel level drops to the preset threshold and locate the nearest gas station based on map information. Therefore, in this second scenario, the nearest gas station can be displayed on the vehicle's screen to facilitate timely refueling for the driver.

[0089] This application provides an energy calculation method, which will be described in detail below:

[0090] Please see Figure 7 This application provides an energy calculation method for vehicles, which includes:

[0091] Step 06: Calculate the vehicle's total energy consumption based on the vehicle's operating information and the preset total energy consumption calculation model. The operating information includes at least the vehicle's navigation information.

[0092] Specifically, a total energy consumption calculation model can be pre-trained based on historical operating information, which can be the operating information of vehicles of the same type as the vehicle on a big data platform. Specifically, the operating data and navigation data of the vehicle during a certain trip, as well as the total energy consumption consumed by the vehicle when ending the trip, can be determined based on the historical operating information. Then, the total energy consumption calculation model is trained based on the operating data, navigation data, and total energy consumption corresponding to multiple trips.

[0093] Therefore, when a user uses the vehicle's navigation function, the vehicle's current operating information can be obtained, including at least the vehicle's navigation information. Then, based on the total energy consumption calculation model and the mileage, driving time, operating mode, and driving style from the operating information, the total energy consumption is calculated to determine the total energy consumed by the vehicle while driving in the current operating mode. In addition, other operating information can be obtained, such as operating data like total battery power, total fuel level, preset fuel-to-electricity conversion coefficient, current battery level, current fuel level, preset equilibrium point threshold, operating mode, and driving style. Navigation data, such as average vehicle speed, can also be obtained, with the navigation data determined by the in-vehicle navigation system. This operating information is then input into the total energy consumption calculation model to calculate the vehicle's total energy consumption, i.e., the energy used for driving during operation.

[0094] Step 07: Calculate the vehicle's remaining battery power and fuel level based on the operating information, the vehicle's total energy consumption, and the vehicle's operating mode.

[0095] Specifically, the operating modes include pure electric mode and hybrid mode. Operating information includes the current battery level. In pure electric mode, the vehicle's driving force is provided solely by the battery. The State of Charge (SOC) is the target value for vehicle battery balance, and a preset balance point threshold can be determined based on the SOC. In hybrid mode, if the current battery level is greater than the preset balance point threshold, the vehicle's driving force is provided solely by the battery. In hybrid mode, if the current battery level is less than the preset balance point threshold, the vehicle's driving force is provided by both the battery and the engine.

[0096] When the vehicle's driving force is provided solely by the battery, the total energy consumption is simply the battery's electrical energy consumption. Therefore, the amount of electricity consumed can be determined based on the total energy consumption, and the remaining electricity can be determined by combining this with the current electricity level in the operating information. In this case, the engine is not running, and there is no fuel loss; therefore, the remaining fuel level can be determined based on the current fuel level in the operating information. That is, in pure electric mode, or in hybrid mode, and when the current electricity level is greater than a preset equilibrium threshold, the remaining electricity level can be directly determined based on the total energy consumption and the current electricity level, and the remaining fuel level can be determined based on the current fuel level.

[0097] When the vehicle's driving force is provided by the battery and engine, the total energy consumption consists of the battery's electrical energy consumption and the engine's energy consumption, where the engine's energy consumption refers to the electrical energy generated by the engine burning fuel. Therefore, an additional energy calculation model can be trained. This model is used only to determine the vehicle's remaining battery power. Current operating information can be input into the trained energy calculation model to determine the vehicle's remaining battery power, thereby determining the battery's electrical energy consumption. A preset fuel-to-electricity conversion coefficient is used to measure the vehicle's efficiency in converting fuel into electrical energy. Based on the total energy consumption and the battery's electrical energy consumption, the engine's energy consumption during vehicle operation can be determined. Then, based on the energy consumption and the preset fuel-to-electricity conversion coefficient, the amount of fuel consumed by the engine can be determined, thus determining the vehicle's remaining fuel.

[0098] Knowing the remaining fuel and battery level, energy information can be displayed on the vehicle's navigation screen. This energy information includes at least the remaining fuel and battery level, for example... Figure 3 This information is displayed so that users can easily check it and thus schedule charging and refueling times accordingly based on the remaining battery and fuel levels.

[0099] The energy calculation method of this application calculates the total energy consumption of a vehicle during operation based on its operating information and a total energy consumption calculation model. Then, it calculates the vehicle's remaining battery power and fuel level based on the operating information, the vehicle's total energy consumption, and the vehicle's operating mode. For example, when the operating mode is pure electric or hybrid, and the current battery power is greater than a preset balance point threshold, the corresponding energy calculation model is a total energy consumption calculation model. The calculated total energy consumption is the energy output by the battery, so the vehicle's remaining battery power can be determined based on the total energy consumption. Then, the remaining fuel level is determined directly based on the current fuel level. When the operating mode is hybrid, and the current battery power is less than a preset balance point threshold, the remaining battery power can be calculated based on the operating information and the corresponding energy calculation model. Then, the amount of fuel consumed by the vehicle is confirmed based on the total energy consumption and the remaining battery power, thereby confirming the vehicle's remaining fuel level. In this way, the total energy consumption, remaining battery power, and remaining fuel level of the vehicle in different operating modes can be accurately calculated, making it easier for users to rationally schedule charging and refueling based on the remaining battery power and remaining fuel level.

[0100] Furthermore, existing technologies can estimate the vehicle's remaining driving range to help users determine when to charge and refuel; however, the estimated remaining driving range can fluctuate significantly depending on the vehicle's driving status. This application, on the other hand, directly calculates the remaining battery and fuel levels at the end of the trip. With clear road information, the fluctuations in the calculated values ​​are smaller, thus improving the user experience.

[0101] Please see Figure 8In some implementations, the operating information includes the current battery level. Step 07: Calculate the vehicle's remaining battery level and remaining fuel level based on the operating information, the vehicle's total energy consumption, and the vehicle's operating mode, including:

[0102] Step 071: When the working mode is hybrid mode, calculate the remaining battery power of the vehicle based on the current battery power and the energy calculation model associated with the hybrid mode.

[0103] Step 072: Calculate the vehicle's remaining fuel based on at least one of the following: operating information, total energy consumption, and remaining battery power.

[0104] Specifically, an energy calculation model corresponding to the hybrid mode can be pre-trained based on historical operating information to calculate whether the battery outputs electrical energy during driving. The vehicle's operating parameters for a specific trip and its remaining charge at the end of the trip can be determined based on historical operating information. Then, an energy calculation model is trained based on the operating parameters and remaining charge for multiple trips. This model can only be used to calculate the remaining charge at the end of a trip based on operating information. Therefore, in the hybrid mode, the vehicle's operating information can be input into the energy calculation model to determine the battery's energy consumption. Combining the current charge level and the energy consumption value, the vehicle's remaining charge can be determined.

[0105] When the vehicle is in hybrid mode, the engine may or may not operate, depending on the current battery level and a preset balance point threshold. If the current battery level is greater than the preset balance point threshold, the engine does not operate, meaning the fuel level remains unchanged; therefore, the remaining fuel level can be determined based on the current battery level in the operating information. If the current battery level is less than the preset balance point threshold, the engine operates, and the fuel level changes; therefore, the remaining fuel level needs to be determined based on the total energy consumption and the remaining battery level. The engine's energy consumption during vehicle operation can be determined based on the total energy consumption and the battery's energy consumption value. Then, the amount of fuel consumed by the engine can be determined based on the energy consumption value and a preset fuel-to-electricity conversion coefficient, thus determining the vehicle's remaining fuel level.

[0106] Thus, in hybrid mode, the vehicle's remaining battery power can be accurately calculated based on the current battery level and the associated energy calculation model. Then, based on the relationship between the current battery level and a preset balance point threshold, the method for calculating the remaining fuel is determined, thereby allowing the vehicle's remaining fuel to be accurately calculated based on at least one of the following: operating information, total energy consumption, and remaining battery power.

[0107] Please see Figure 9In some implementations, the operating information also includes the vehicle's power-saving mode. When the current battery level is less than a preset balance point threshold, step 071: In hybrid mode, the remaining battery level of the vehicle is calculated based on the current battery level and the energy calculation model associated with the hybrid mode, including:

[0108] Step 0711: Obtain the vehicle's historical operating information;

[0109] Step 0712: Calculate the vehicle's remaining battery power based on the vehicle's historical operating information and the energy calculation model corresponding to the power preservation mode;

[0110] Step 072: Calculate the vehicle's remaining fuel based on at least one of the following: operating information, total energy consumption, and remaining battery power, including:

[0111] Step 0721: Calculate the vehicle's remaining fuel based on total energy consumption and remaining electricity.

[0112] Specifically, when the vehicle is operating in hybrid mode and the current battery level is below a preset equilibrium threshold, the vehicle will enter a battery protection mode. This mode includes intelligent battery protection and forced battery protection, with different strategies. Intelligent battery protection prioritizes energy efficiency; when the engine has excess output power, it automatically uses this energy to replenish the battery. Forced battery protection ensures the vehicle maintains its battery level according to the owner's preset target. When the battery level falls below a preset value, the engine actively intervenes, driving the generator to charge the battery and stably maintain the preset charge level. Therefore, the generator's output varies depending on the vehicle's battery protection mode, resulting in potentially different remaining battery charge levels during operation.

[0113] Therefore, corresponding energy calculation models can be set for the two power preservation modes respectively, so as to calculate the vehicle's remaining power based on the energy calculation model that is the same as the vehicle's current power preservation strategy. If it is determined that the vehicle is operating in hybrid mode and the current power level is less than a preset equilibrium point threshold, the vehicle's power preservation mode also needs to be determined. If the vehicle's power preservation mode is determined to be intelligent power preservation mode, the remaining power level after the vehicle completes its journey is calculated based on the operating data, navigation data, and the energy calculation model corresponding to intelligent power preservation mode. If the vehicle's power preservation mode is determined to be forced power preservation mode, the remaining power level after the vehicle completes its journey can be calculated based on the operating data, navigation data, and the energy calculation model corresponding to forced power preservation mode.

[0114] In this way, different power preservation modes can be set up separately, and the remaining power can be calculated according to the power preservation mode corresponding to the current power preservation mode of the vehicle. This incorporates the influence of the power preservation mode in the calculation process, and prevents the power preservation strategy corresponding to the power preservation mode from being different from the current power preservation strategy of the vehicle, which would result in a lower accuracy of the remaining power calculation, thereby improving the accuracy of the remaining power calculation.

[0115] Please see Figure 10 In some implementations, the power-saving mode includes a forced power-saving mode. Step 0712: Calculate the vehicle's remaining power capacity based on the vehicle's historical operating information and the energy calculation model corresponding to the power-saving mode, including:

[0116] Step 07121: Train the first power calculation model corresponding to the forced power supply mode based on historical operation information, so that the first power calculation model converges;

[0117] Step 07122: Calculate the vehicle's remaining battery power based on the converged first energy calculation model.

[0118] Specifically, historical operation information includes historical operation data and historical navigation data. Feature parameters for the model can be extracted from this data, including but not limited to: initial battery level, preset equilibrium point threshold, mileage, trip time, operating mode, average vehicle speed, driving style, initial battery level range, and equilibrium point range. The initial battery level range and equilibrium point range are generated using a K-means clustering algorithm. The energy calculation model can then be trained based on these feature parameters.

[0119] A first energy calculation model corresponding to the forced power-saving mode can be trained based on historical operating information of a vehicle operating in forced power-saving mode, with the current battery level below a preset equilibrium threshold and in hybrid mode, to ensure convergence of the first energy calculation model corresponding to the forced power-saving mode. For example, based on historical operating information, the vehicle's operating data and navigation data during a certain trip, as well as the remaining battery level at the end of the trip, can be determined. Then, based on feature parameters, operating data, navigation data, and remaining battery level of multiple trips corresponding to forced power-saving modes, the first energy calculation model corresponding to the forced power-saving mode is trained to ensure convergence of the first energy calculation model.

[0120] Given the historical operating information corresponding to the forced power supply mode, this information can be divided into a training set and a validation set to improve the training effect of the first power calculation model.

[0121] When the current battery level is less than the preset balance point threshold and the power preservation mode is the forced power preservation mode, the current operating information can be input into the converged first energy calculation model to calculate the vehicle's remaining battery level.

[0122] In this way, a first energy calculation model can be trained based on historical operating information corresponding to the forced power-saving mode. This allows for the calculation of the vehicle's remaining power capacity based on the first energy calculation model when the power-saving mode is in forced mode, thereby improving the accuracy of the remaining power capacity calculation. Furthermore, compared to existing technologies, this application involves fewer parameters, the energy calculation model is easier to train, and it consumes fewer resources, thus reducing computational burden.

[0123] Please see Figure 11 In some implementations, the power-saving mode includes an intelligent power-saving mode. Step 0712: Calculate the vehicle's remaining power based on the vehicle's historical operating information and the energy calculation model corresponding to the power-saving mode, including:

[0124] Step 07123: Train the second power calculation model corresponding to the intelligent power supply mode based on historical operation information, so that the second power calculation model converges;

[0125] Step 07124: Calculate the vehicle's remaining battery power based on the converged second energy calculation model.

[0126] Specifically, similar to training the first energy calculation model, a second energy calculation model corresponding to the intelligent power-saving mode can be trained based on historical operating information of the vehicle operating in intelligent power-saving mode, with the current battery level below a preset balance point threshold, and in hybrid mode. This ensures the convergence of the second energy calculation model corresponding to the intelligent power-saving mode. For example, historical operating information can be used to determine the vehicle's operating data and navigation data during a certain trip while operating in intelligent power-saving mode, as well as the remaining battery level at the end of the trip. Then, based on feature parameters, operating data, navigation data, and remaining battery level of trips corresponding to multiple intelligent power-saving modes, the second energy calculation model corresponding to the intelligent power-saving mode is trained.

[0127] Once the historical operating information corresponding to the intelligent power supply mode is obtained, this information can be divided into a training set and a validation set to improve the training effect of the second power calculation model.

[0128] When the current battery level is less than the preset balance point threshold and the power protection mode is set to intelligent power protection mode, the current operating information can be input into the converged second energy calculation model to calculate the vehicle's remaining battery level.

[0129] In this way, a second energy calculation model can be trained based on the historical operating information corresponding to the intelligent power-saving mode. This allows for the calculation of the vehicle's remaining battery power based on the second energy calculation model when the power-saving mode is in intelligent mode, thereby improving the accuracy of the remaining battery power calculation. Furthermore, compared to existing technologies, this application involves fewer parameters, the energy calculation model is easier to train, and it consumes fewer resources, thus reducing computational burden.

[0130] Please see Figure 12 In some implementations, step 0711: obtaining historical operating information of the vehicle, further includes:

[0131] Step 07111: Based on preset filtering parameters and preset interpolation rules, filter and interpolate the exported information from the big data platform to obtain intermediate running information;

[0132] Step 07112: Based on preset filtering conditions and intermediate running information, obtain historical running information corresponding to multiple historical trip segments.

[0133] Specifically, the process begins by exporting information from the big data platform. Then, based on preset filtering parameters and interpolation rules, this exported information is filtered and interpolated to obtain intermediate operational information. Various preset filtering parameters can be used, and specific settings can be configured as needed. For example, preset filtering parameters may include at least one of the following: vehicle type, battery range (in kilometers), current battery level, operating mode, running mode, average vehicle speed, driving distance, and trip time. The amount of exported data can be modified according to the accuracy requirements of the model training; the higher the required computational accuracy of the model, the larger the amount of data needs to be exported.

[0134] After obtaining the exported information, it can be categorized based on vehicle type and battery range mileage to ensure that the historical operational information used in each training session comes from the same vehicle model and battery range version. Further filtering of the operational information can be performed based on other preset filtering parameters. For example, to improve the relevance of the energy calculation model and operating mode, the exported information can be filtered based on the operating mode. Similarly, to improve the relevance of the energy calculation model to driving distance and travel time, the exported information can be filtered based on driving distance and travel time, facilitating subsequent training to obtain energy calculation models corresponding to long-distance, long-duration operations, as well as those corresponding to short-distance, short-duration operations. Preset filtering parameters may also include average vehicle speed. When the average vehicle speed is below a preset speed threshold, such as below 10 m / s, the vehicle consumes less energy; therefore, exported information with an average speed below the preset speed threshold can be filtered out. Alternatively, exported information that is in the charging phase of a charging station can be filtered out. For example, if the battery charge increases but the vehicle speed remains at 0 for a certain period of time, then it can be confirmed that the exported information in this period of time corresponds to the charging phase of a charging station, and this exported information can be filtered out.

[0135] When a vehicle is traveling a certain distance, its signal may be weak at some point, preventing data from being uploaded to the big data platform. This results in the platform not providing the data corresponding to that moment. Therefore, based on preset interpolation rules, filtered information can be interpolated to fill in the missing data, thus obtaining complete intermediate operational information that can be used for training the energy calculation model. For example, the preset interpolation rule could be "previous term filling," where the values ​​of the previous one or several data points are used to fill the currently missing data point. It should be noted that data from the same travel distance should be used for interpolation to ensure accuracy.

[0136] Next, based on preset filtering conditions and intermediate operation information, historical operation information corresponding to multiple historical trips is obtained.

[0137] For example, when training the energy calculation model corresponding to the hybrid mode, it is necessary to obtain the historical operation information corresponding to the hybrid mode. Therefore, the preset screening conditions can be: the selection start condition is that the current energy is less than the preset balance point threshold and the working mode is hybrid mode; the selection termination condition is the change of operating mode, the change of the preset balance point threshold, or the change of working mode.

[0138] The selection criteria for each segment of operation information are: the current battery level is less than a preset balance point threshold, and the operating mode is hybrid mode. That is, only when the current battery level of a certain intermediate operation information segment is less than the preset balance point threshold and the operating mode is hybrid mode, is that intermediate operation information confirmed as historical operation information. This intermediate operation information is the first frame of the historical operation information for the corresponding trip. Then, intermediate operation information following this segment can be confirmed as historical operation information to obtain the historical operation information corresponding to that trip segment.

[0139] The termination condition for selecting each segment of operation information is a change in the operation mode, a change in the preset balance point threshold, or a change in the working mode. That is, if the operation mode, preset balance point threshold, or working mode of a certain operation information is different from the operation mode, preset balance point threshold, or working mode corresponding to that segment of the trip, then the acquisition of operation information will stop. The historical operation information acquired before this operation information is the complete historical operation information corresponding to this trip.

[0140] In this way, historical operation information corresponding to multiple historical trips with the hybrid mode can be obtained.

[0141] For example, intermediate operation information includes operation information A, operation information B, operation information C, operation information D, and operation information E. Operation information A indicates that the current battery level is less than the preset balance point threshold and the operating mode is hybrid mode. Operation information E indicates that the operating mode is pure electric mode. Therefore, historical operation information includes operation information A, operation information B, operation information C, and operation information D. Operation information A is the first frame of historical operation information corresponding to this historical trip, and operation information D is the last frame of historical operation information corresponding to this historical trip.

[0142] In this way, the information of the big data platform can be cleaned and interpolated by using preset filtering parameters and preset interpolation rules to ensure the integrity of historical operation information. Preset filtering conditions can be used to obtain historical operation information corresponding to multiple historical trips, thereby ensuring that the historical operation information meets the training needs of the power calculation model.

[0143] In some implementations, historical operating information may include power preservation method, initial battery level at the start of the trip, preset balance point threshold, final battery level at the end of the trip, mileage, trip time, operating mode, running mode, average vehicle speed, and driving style. Specifically, the initial battery level at the start of the trip is the remaining battery level in the first frame of the selected data segment (i.e., the intermediate operating information corresponding to multiple trips); the final battery level at the end of the trip is the remaining battery level in the last frame of the selected data segment; the mileage is the difference between the last frame and the first frame of the total mileage of the selected data segment; the trip time is the difference between the last frame and the first frame of the time of the selected data segment; the average vehicle speed is the ratio of mileage to trip time; and the driving style is calculated based on information such as the vehicle's average acceleration and average throttle depth during the previous trip. The energy calculation model can be trained based on the above historical operating information to quickly obtain an energy calculation model with better calculation performance.

[0144] Please see Figure 13 In some implementations, the operating information also includes the total battery energy and current fuel level. Step 0721: Calculate the vehicle's remaining fuel level based on the total energy consumption and remaining battery power, including:

[0145] Step 07211: Calculate the remaining fuel based on the battery's total energy, total energy consumption, remaining power, current fuel level, current power, and preset fuel-to-electricity conversion coefficient.

[0146] Specifically, when the working mode is hybrid mode and the current battery level is less than the preset balance point threshold, the battery may be in a charging state, a discharging state, or a state of simultaneous charging and discharging. This means that the total energy consumption may only correspond to the electricity generated by the generator driven by the engine, or the total energy consumption may correspond to the electricity generated by the generator driven by the engine and the electricity generated when the battery is discharging.

[0147] The energy calculation model can be used to calculate the remaining battery power when a vehicle finishes its journey based on operational information. Therefore, operational information can be input into the energy calculation model, such as operational data and navigation data. The model can then calculate the remaining battery power based on this data, allowing the battery status to be determined and the amount of fuel consumed during the journey to be calculated based on the battery status and total energy consumption.

[0148] Next, the battery's state during driving can be determined based on the calculated remaining charge. If the remaining charge is greater than the battery's current charge, the battery is confirmed to be charging. The energy used for charging is generated by the engine driving the generator. In this case, the engine's output is used to drive the vehicle and also to charge the battery; the calculated total energy consumption corresponds to the output of the engine driving the generator. If the remaining charge is less than the battery's current charge, the battery is confirmed to be discharging. In this case, the engine's output is only used to drive the vehicle; the calculated total energy consumption corresponds to the output of the engine driving the generator and the output of the battery during discharge.

[0149] At this point, the remaining fuel level can be calculated based on the total battery energy, total energy consumption, remaining charge, current fuel level, current charge, preset fuel-to-electricity conversion coefficient, and total battery energy. The preset fuel-to-electricity conversion coefficient measures the vehicle's efficiency in converting fuel into electricity.

[0150] After determining the remaining battery level, the remaining battery energy at the end of the trip can be calculated based on the remaining battery level, and the battery energy at the start of the trip can be determined based on the current battery level and the total battery energy. The difference between the energy at the start and end of the trip can be used to indicate whether the battery was charged during the trip. If the difference between the energy at the end and start of the trip is less than 0, the battery has discharged, and part of the total energy consumption is provided by the battery. If the difference between the energy at the end and start of the trip is greater than 0, the battery has charged, and the total energy consumption is entirely provided by the engine, with the engine also providing some energy to charge the battery.

[0151] Therefore, the energy generated by the engine can be calculated based on the total energy consumption and the difference between the battery's energy at the end of the trip and its energy at the beginning of the trip. Then, the amount of fuel consumed by the engine can be determined based on the preset fuel-to-electricity conversion coefficient and the calculated energy generated by the engine. The difference between the current fuel level (i.e., the fuel level at the beginning of the trip) and the amount of fuel consumed by the engine is the remaining fuel level. The formula used at this time is as follows:

[0152] E gas_end = E gas -(E p +(E bat_p -E bat_max ×SOC)) / k (1)

[0153] Among them, E gas_end E represents the remaining oil volume. gas E represents the current oil level. p For total energy consumption, E bat_p E is the remaining electrical energy. bat_max is the total battery energy, SOC is the current charge level, and k is the preset oil-to-electric conversion coefficient.

[0154] Thus, when the vehicle is operating in hybrid mode and the current battery level is below a preset equilibrium threshold, the remaining battery level can be calculated based on the operating information and the energy calculation model corresponding to the hybrid mode, thereby determining the battery's operating state. Next, the amount of fuel consumed during driving can be calculated based on the total energy consumption and the remaining battery level. After confirming the energy generated by the vehicle's fuel consumption, the amount of fuel consumed can be determined, thus confirming the vehicle's remaining fuel level. In this way, the vehicle's total energy consumption, remaining battery level, and remaining fuel level can be accurately calculated, allowing users to rationally schedule charging and refueling based on the remaining battery level and fuel level.

[0155] Please see Figure 14 In some implementations, when the current battery level is greater than or equal to a preset equilibrium point threshold, the energy calculation model associated with the hybrid mode is a total energy consumption calculation model. When the current battery level is greater than or equal to the preset equilibrium point threshold, step 071: when the operating mode is hybrid mode, calculate the vehicle's remaining battery level based on the current battery level and the energy calculation model associated with the hybrid mode, including:

[0156] Step 0713: Calculate the remaining power based on the total energy consumption and the current power level;

[0157] Step 072: Calculate the vehicle's remaining fuel based on at least one of the following: operating information, total energy consumption, and remaining battery power, including:

[0158] Step 0722: Calculate the vehicle's remaining fuel based on the current fuel level in the operation information.

[0159] Specifically, when the vehicle is operating in hybrid mode and the current battery level is greater than or equal to a preset equilibrium point threshold, the vehicle's power source is the battery. The total energy consumption calculation model calculates all the energy output from the battery. Therefore, when the current battery level is greater than or equal to the preset equilibrium point threshold, the energy calculation model associated with hybrid mode is the total energy consumption calculation model. At this time, the vehicle's initial energy level can be determined by multiplying the current battery level by the total battery energy. The difference between the initial energy level and the total energy consumption is the vehicle's remaining energy. The formula used in this case is as follows:

[0160] E bat_end = E bat_max ×SOC-E p (2)

[0161] Among them, E p For total energy consumption, E bat_max E represents the total battery energy, SOC represents the current battery charge. bat_end This is the remaining electrical energy.

[0162] The remaining battery power of the vehicle can then be determined based on the remaining electrical energy, for example, by using the ratio of the remaining electrical energy to the total battery energy as the remaining battery power.

[0163] When the vehicle is operating in hybrid mode and the current battery level is greater than or equal to the preset balance point threshold, the engine does not work and does not consume fuel. Therefore, the remaining fuel level can be calculated directly based on the current fuel level.

[0164] In this way, when the vehicle is operating in hybrid mode and the current battery level is greater than or equal to the preset balance point threshold, the remaining battery level can be accurately determined based on the total energy consumption and the current battery level, and the remaining fuel level can be accurately determined based on the current fuel level. This makes it easier for users to rationally arrange the timing of charging and refueling based on the remaining battery level and remaining fuel level.

[0165] Please see Figure 15 In some implementations, the operating information includes the current battery level and current fuel level. Step 07: Calculate the vehicle's remaining battery level and remaining fuel level based on the operating information, the vehicle's total energy consumption, and the vehicle's operating mode, including:

[0166] Step 073: When the working mode is pure electric mode, calculate the vehicle's remaining battery power based on the current battery power and total energy consumption;

[0167] Step 074: Calculate the vehicle's remaining fuel level based on the current fuel level.

[0168] Specifically, when the vehicle is operating in pure electric mode, the power source of the vehicle is the battery, and the total energy consumption is the energy output by the battery. At this time, the vehicle's energy at the beginning of the trip can be determined by multiplying the current energy level by the total battery energy. The difference between the energy at the beginning of the trip and the total energy consumption is the vehicle's remaining energy. The remaining energy of the vehicle is then calculated using the formula (2) above. The remaining battery capacity can then be determined based on the remaining energy, for example, by using the ratio of the remaining energy to the total battery energy as the remaining battery capacity.

[0169] When the vehicle is running in pure electric mode, the engine does not consume fuel, so the remaining fuel can be calculated directly based on the current fuel level.

[0170] In this way, when the vehicle is running in pure electric mode, the remaining battery power can be accurately determined based on the total energy consumption and the current battery power, and the remaining fuel level can be accurately determined based on the current fuel level, so that users can make reasonable arrangements for charging and refueling based on the remaining battery power and fuel level.

[0171] Please see Figure 16 In some implementations, the energy calculation method further includes:

[0172] Step 08: If the current battery level is greater than the preset balance point threshold, confirm the vehicle's battery power supply to determine the vehicle's operating mode during operation based on the battery power supply.

[0173] Specifically, the current battery level can only be used to determine the relationship between the current battery level and the preset balance point threshold at the start of the trip. Even if the current battery level is greater than the preset balance point threshold at the start of the trip, the current battery level may drop below the preset balance point threshold during vehicle operation, at which point the vehicle's power source will change.

[0174] Therefore, if the current battery level is confirmed to be greater than the preset balance point threshold, the relationship between the vehicle's current battery level and the preset balance point threshold can be further confirmed based on the relationship between the battery's available power and total energy consumption during driving.

[0175] First, the energy that the battery can supply can be determined using the following formula:

[0176] E bat = E bat_max ×(SOC-SOC min (3)

[0177] Among them, E bat E can be powered by batteries bat_max The total battery energy is SOC, which is the current battery level. min This is the preset equilibrium point threshold.

[0178] If the battery's available power exceeds the total energy consumption, it can be confirmed that the battery's charge will not drop below the preset balance point threshold after the vehicle completes its journey. The battery remains the sole power source during driving, and the operating mode will not change. Therefore, the fuel and charge calculation methods can be applied based on whether the vehicle is in pure electric or hybrid mode, and the current charge level is above the preset balance point threshold. If the vehicle's current operating mode is pure electric, the remaining charge and fuel level after the journey are calculated based on steps 073 and 074 above. If the vehicle's current operating mode is hybrid, the remaining charge and fuel level are calculated based on steps 0713 and 0722 above.

[0179] When the battery's available power is less than the total energy consumption, it can be confirmed that during vehicle operation, the battery's charge will drop below a preset equilibrium threshold, causing a change in the vehicle's power source. When the charge level is above the preset equilibrium threshold, the vehicle's power source is the battery; when the charge level is below the preset equilibrium threshold, the vehicle's power source is both the battery and the engine. At this time, the vehicle's operating mode may change. If the current operating mode is hybrid mode, the operating mode remains unchanged, but the vehicle's power source changes. If the current operating mode is electric mode, and the operating mode changes to hybrid mode, the vehicle's power source changes.

[0180] Therefore, the change in the calculated battery level during vehicle operation can be calculated to determine the moment when the calculated battery level will drop to a preset equilibrium point threshold. Then, if the calculated battery level is greater than the preset equilibrium point threshold, the remaining fuel and remaining battery level at the moment when the battery level drops to the preset equilibrium point threshold are calculated based on the fuel calculation method and battery level calculation method corresponding to the operating condition of pure electric mode or hybrid mode and the current battery level being greater than the preset equilibrium point threshold, specifically determined according to the vehicle's current operating mode. If the calculated battery level is less than the preset equilibrium point threshold, the final remaining battery level and remaining fuel level of the vehicle are calculated based on the fuel calculation method and battery level calculation method corresponding to the operating mode being hybrid mode and the current battery level being less than the preset equilibrium point threshold, i.e., steps 0711, 0712, and 0721 mentioned above.

[0181] When the current battery level is less than the preset balance point threshold, the vehicle operates in hybrid mode. The remaining battery level and battery level can be calculated based on the fuel and battery level calculation methods corresponding to the hybrid mode and the current battery level being less than the preset balance point threshold, namely steps 0711, 0712 and 0721 above.

[0182] In this way, the relationship between the vehicle's current battery level and the preset balance point threshold can be determined based on the battery's available power and total energy consumption. The vehicle's final remaining battery level and remaining fuel level can be calculated based on the corresponding fuel energy calculation method and battery energy calculation method, thereby improving the accuracy of the calculation of remaining battery level and remaining fuel level.

[0183] Please see Figure 17 In some implementations, the control method further includes:

[0184] Step 09: If the remaining battery power is less than the preset battery power threshold, calculate the vehicle's first driving position when the vehicle's battery power drops to the preset battery power threshold, and obtain the location of the nearest charging station to the first driving position;

[0185] Step 010: If the remaining fuel level is less than the preset fuel level threshold, calculate the vehicle's second driving position when the vehicle's fuel level drops to the preset fuel level threshold, and obtain the location of the nearest gas station to the second driving position.

[0186] Specifically, when the calculated remaining battery power is less than a preset battery power threshold, the vehicle's first driving position when the battery power drops to the preset battery power threshold can be calculated, and the nearest charging station to the first driving position can be obtained based on map information. Then, the nearest charging station to the first driving position can be displayed on the vehicle's screen so that the driver can complete the charging in a timely manner.

[0187] If the calculated remaining fuel level is less than a preset fuel level threshold, the vehicle's second driving position can be calculated when the fuel level drops to the preset fuel level threshold. The nearest gas station to the second driving position can be obtained based on map information and then displayed on the vehicle's screen so that the driver can refuel in a timely manner.

[0188] Please see Figure 18 To facilitate better implementation of the display method of this application, this application also provides a display device 10. The display device 10 may include a display module 11. The display module 11 is used to display energy information based on navigation data for a predetermined vehicle trip; the energy information includes at least the remaining battery power and remaining fuel level when the vehicle ends the predetermined trip based on the navigation data.

[0189] The display module 11 is specifically used to display navigation information, which is determined based on navigation data. The navigation information includes at least one of the following: the starting position of the predetermined trip, the target position, the estimated travel time, the mileage, the route, the trip time, and the average speed.

[0190] The display module 11 is specifically used to display historical driving styles, which are determined based on historical driving data.
