[0003] In the series working condition, when the SOC (State of Charge) is lower than the lower limit value, the engine is started to start charging, and when the SOC is higher than the upper limit value, the engine is stopped and pure electric driving is adopted. This causes the SOC to fluctuate between the upper and lower limit values during actual driving, that is, the power battery is always charging and discharging. There is an efficiency loss in the charging and discharging process, and frequent charging and discharging also increases energy consumption and affects the service life of the battery. SUMMARY

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.
[0056] To enable those skilled in the art to better understand this application, firstly, in conjunction with Figure 1 A brief description of the application scenarios involved in this application is provided.
[0057] See Figure 1 The diagram illustrates a scenario where the vehicle power generation control method of the embodiments of this application can be applied.
[0058] The vehicle-side controller 102 of the target vehicle acquires the current power parameters of the target vehicle in the current period; wherein the target vehicle is a series hybrid vehicle; based on the current power parameters and the historical power parameters of the target vehicle in the historical period, it predicts the predicted power consumption parameters of the target vehicle in the next period; based on the predicted power consumption parameters and the basic compensation power, it determines the total power generation of the target vehicle in the next period; and controls the power generation of the target vehicle in the next period to be the total power generation.
[0059] The vehicle-side controller 102 of the target vehicle can directly obtain current power parameters, historical power parameters, and basic compensation power from the local machine, or it can communicate with the server 104 via the network to obtain historical power parameters from the data storage system. The data storage system can be integrated on the server 104, or it can be located in the cloud or on other network servers. The server 104 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.
[0060] In one exemplary embodiment, refer to Figure 2 The flowchart illustrating the control of vehicle power generation in an embodiment of this application is shown below in detail:
[0061] Step 201: Obtain the current power parameters of the target vehicle in the current cycle.
[0062] The target vehicle is a hybrid electric vehicle, specifically a series hybrid electric vehicle. When the battery is fully charged, the engine does not operate, and the vehicle operates on pure electric power. When the battery is low on power, the engine starts to drive the generator to produce electricity and charge the battery.
[0063] The current power parameters of the target vehicle are periodically acquired. For example, a period of 10 milliseconds is used, and the vehicle-side controller acquires the current power parameters of the target vehicle every 10 milliseconds. The current power parameters of the target vehicle are used to characterize the current total power consumption of the target vehicle. The current power parameters can be obtained by direct reading or by theoretical calculation based on various operating parameters of the target vehicle. This embodiment does not limit the specific method of acquiring the current power parameters.
[0064] Step 202: Based on the current power parameters and the historical power parameters of the target vehicle in the historical period, predict the predicted power consumption parameters of the target vehicle in the next period.
[0065] The historical time period refers to the period preceding the current cycle, including several complete cycles. For example, the time period corresponding to 20 milliseconds, 30 milliseconds, or 100 milliseconds before the start time of the current cycle. The historical power parameter is the total vehicle power consumption obtained within the historical time period. The vehicle-side controller can store the current power parameter obtained in each cycle locally or on a server, so that it can be used as historical power parameter in subsequent cycles.
[0066] Specifically, the historical power parameters of the target vehicle within a historical period are obtained, and combined with the current power parameters of the target vehicle in the current period, the trend of the vehicle's total power consumption is analyzed. When the period length is extremely short, it can be almost certain that the trend remains unchanged, thereby predicting the vehicle's total power consumption in the next period and obtaining the predicted power consumption parameters.
[0067] Optionally, differential calculations can be performed based on the current power parameters and historical power parameters to obtain the predicted power consumption parameters.
[0068] Optionally, an algorithm model for the total power consumption of the target vehicle can be constructed by inputting the current power parameters and historical power parameters into the algorithm model to obtain the output predicted power consumption parameters.
[0069] Step 203: Determine the total power generation of the target vehicle in the next cycle based on the predicted power consumption parameters and the basic compensation power.
[0070] Since the actual efficiency of energy conversion varies with load or temperature, there is a certain error between the theoretical value and the actual value. Therefore, a basic compensation power is introduced to dynamically compensate the power consumption of the whole vehicle, thereby determining a more accurate and reasonable total power generation.
[0071] Optionally, based on the vehicle status of the target vehicle in the current period, the corresponding basic compensation parameters are obtained, and then the total power generation is calculated by combining the predicted power consumption parameters and the basic compensation parameters.
[0072] Optionally, based on the current current and current voltage of the target vehicle's power battery, real-time basic compensation parameters are calculated, and then combined with the predicted power consumption parameters and basic compensation parameters, the total power generation is calculated.
[0073] Step 204: Control the power generation of the target vehicle in the next cycle to the total power generation.
[0074] The vehicle-side controller will control the power generation of the target vehicle in the next cycle to the total power generation determined in the above steps, so that the power generation is as equal as possible to the power consumption of the whole vehicle, and the power battery does not need to undergo charging and discharging processes.
[0075] In this application, the current power parameters of a target vehicle in the current cycle are obtained; wherein the target vehicle is a series hybrid vehicle; based on the current power parameters and the historical power parameters of the target vehicle in a historical period, the predicted power consumption parameters of the target vehicle in the next cycle are predicted; based on the predicted power consumption parameters and the basic compensation power, the total power generation of the target vehicle in the next cycle is determined; and the power generation of the target vehicle in the next cycle is controlled to be the total power generation. The technical solution provided by this application can predict the actual power consumption in the next cycle, and by controlling the balance between power generation and actual power consumption, the number of charge-discharge cycles of the power battery during driving is reduced, thereby reducing overall vehicle energy consumption and extending the lifespan of the power battery.
[0076] Based on the above embodiments, in an exemplary embodiment, the historical time period includes a first historical period and a second historical period, where the first historical period is the previous period of the current period, and the second historical period is the previous period of the first historical period. (See also...) Figure 3 The flowchart illustrating the detailed process of determining the predicted power consumption parameters in an embodiment of this application is shown, specifically including:
[0077] Step 301: Based on the current power parameters, the first historical power parameters of the target vehicle in the first historical period, and the second historical power parameters of the target vehicle in the second historical period, determine the power change parameters of the target vehicle.
[0078] The historical period includes the two periods preceding the current period. For example, a period is 10 milliseconds. The period 10 milliseconds before the start time of the current period corresponds to the first historical period, and the period from 20 milliseconds before the start time of the current period to 10 milliseconds before the start time corresponds to the second historical period.
[0079] The second historical power parameter, the first historical power parameter, and the current power parameter form a parameter sequence. The changing trend of the power parameter can be obtained by differential calculation, and the changing power parameter is used to characterize the changing trend.
[0080] Optionally, the changing trends between the second historical power parameter and the first historical power parameter, as well as the changing trends between the first historical power parameter and the current power parameter, are calculated separately, and then the power change parameters are obtained by comprehensive trend analysis.
[0081] Step 302: The sum of the power change parameter and the current power parameter is used as the predicted power consumption parameter of the target vehicle in the next cycle.
[0082] It should be noted that, in order to ensure the accuracy of the prediction results, the cycle length set in this embodiment is extremely short. Therefore, during the power-on initialization process of the target vehicle, many cycles have already been experienced. When the control method provided in this embodiment is used to control the power generation of the target vehicle, there must be at least two historical cycles before the current cycle, namely the first historical cycle and the second historical cycle.
[0083] In this application, the historical period is specifically divided into a first historical period and a second historical period to accurately measure the power change parameters of the target vehicle and predict the power consumption parameters for the next period. Compared with a longer historical period, differential calculation based on the first and second historical periods can more accurately measure the power change parameters, thereby improving the accuracy of the prediction results.
[0084] Based on the above embodiments, in an exemplary embodiment, the current power parameters include the current drive power and the current accessory power, and the historical power parameters include the historical drive power and the historical accessory power. See [link to previous embodiment]. Figure 4 The flowchart illustrating the detailed process of determining power variation parameters in an embodiment of this application is shown, specifically including:
[0085] Step 401: Determine the driving power change parameters of the target vehicle based on the current driving power, the first historical driving power of the target vehicle in the first historical period, and the second historical driving power of the target vehicle in the second historical period.
[0086] Specifically, the current power parameters include, but are not limited to, the current drive power. Drive power is an important component of the vehicle's power consumption, representing the power consumed for driving. The second historical drive power, the first historical drive power, and the current drive power form a parameter sequence. The changing trends between the second historical drive power and the first historical drive power, as well as between the first historical drive power and the current drive power, are calculated separately. Then, the driving power change parameters are obtained by comprehensively analyzing the changing trends.
[0087] Optionally, the difference between the current driving power and the first historical driving power is determined as the first driving power change; the difference between the first historical driving power and the second historical driving power is determined as the second driving power change; and the average of the first driving power change and the second driving power change is used as the driving power change parameter of the target vehicle.
[0088] That is, differential calculations are used to determine the driving power variation parameters of the target vehicle. The difference in driving power between the current cycle and the previous cycle (the first historical cycle) is calculated, as well as the difference in driving power between the two previous cycles (the first historical cycle and the second historical cycle). The average of these two differences is determined as the current driving power variation parameter.
[0089] It should be noted that the first change in drive power is obtained by subtracting the first historical drive power from the current drive power, and similarly, the second change in drive power is obtained by subtracting the second historical drive power from the first historical drive power. Therefore, both the first and second changes in drive power may be negative, and consequently, the current drive power change parameter may also be negative.
[0090] Step 402: Determine the accessory power change parameters of the target vehicle based on the current accessory power, the first historical accessory power of the target vehicle in the first historical period, and the second historical accessory power of the target vehicle in the second historical period.
[0091] Specifically, the current power parameter includes, but is not limited to, the current accessory power. Accessory power is an important component of the vehicle's total power consumption, representing the power consumed by auxiliary equipment, such as the total power consumed by equipment like air conditioning, interior and exterior lights, etc. The second historical accessory power, the first historical accessory power, and the current accessory power form a parameter sequence. The changing trends between the second historical accessory power and the first historical accessory power, as well as between the first historical accessory power and the current accessory power, are calculated separately. Then, a comprehensive trend analysis is performed to obtain the accessory power change parameter.
[0092] Optionally, the difference between the current accessory power and the first historical accessory power is determined as the first accessory power change; the difference between the first historical accessory power and the second historical accessory power is determined as the second accessory power change; and the average of the first accessory power change and the second accessory power change is used as the accessory power change parameter of the target vehicle.
[0093] That is, differential calculations are used to determine the accessory power variation parameters of the target vehicle. The difference in accessory power between the current cycle and the previous cycle (first historical cycle) is calculated, as well as the difference in accessory power between the two previous cycles (first historical cycle and second historical cycle). The average of these two differences is determined as the current accessory power variation parameter.
[0094] It should be noted that the first accessory power change is obtained by subtracting the first historical accessory power from the current accessory power, and similarly, the second accessory power change is obtained by subtracting the second historical accessory power from the first historical accessory power. Therefore, both the first and second accessory power changes may be negative, and consequently, the current accessory power change parameter may also be negative.
[0095] In this application, driving power and accessory power are distinguished, and the corresponding power change parameters are analyzed from at least two aspects. This allows for a more precise measurement of the power change parameters, thereby improving the accuracy of the prediction results. In cases of extremely short cycles, the changes in driving power and accessory power in the two preceding cycles can be determined through differentiation, thus obtaining the corresponding power change parameters. This eliminates the need for additional computational resources, resulting in a fast and accurate control chain and rapid vehicle-side response, enabling stable driving of the target vehicle.
[0096] Accordingly, based on the above embodiments, in an exemplary embodiment, see [link to example]. Figure 5 The flowchart illustrating the detailed process of determining the predicted power consumption parameters in an embodiment of this application is shown, specifically including:
[0097] Step 501: The sum of the driving power change parameters and the current driving power is used as the predicted driving power of the target vehicle in the next cycle.
[0098] For example, P Prop0 P represents the current drive power. Prop1 P represents the first historical drive power. Prop2 P represents the second historical drive power. Prop_pre This indicates the predicted drive power.
[0099] Therefore, P Prop_pre =[(P Prop0 -P Prop1 )+(PProp1 -P Prop2 )] / 2+P Prop0 .
[0100] Step 502: The sum of the accessory power change parameters and the current accessory power is used as the predicted accessory power of the target vehicle in the next cycle.
[0101] For example, P Aux0 P represents the current power of the accessory. Aux1 P represents the power of the first historical attachment. Aux2 P represents the power of the second historical attachment. Aux_pre This indicates the predicted power of the attachment.
[0102] Therefore, P Aux_pre =[(P Aux0 -P Aux1 )+(P Aux1 -P Aux2 )] / 2+P Aux0 .
[0103] In this application, the predicted driving power and predicted accessory power are calculated by combining the power change parameters and the current power parameters, thereby optimizing the power prediction method under series operation.
[0104] Based on the above embodiments, in an exemplary embodiment, the basic compensation power is the product of the current current and the current voltage of the target vehicle's power battery, and the predicted power consumption parameters include the predicted drive power and the predicted accessory power. The sum of the predicted drive power, the predicted accessory power, and the basic compensation power is taken as the total power generation of the target vehicle in the next cycle.
[0105] Specifically, the current current and voltage of the power battery (current and voltage corresponding to the start time of the current cycle) are obtained, and the product of the current current and voltage is calculated as the base compensation power. It should be noted that the base compensation power can be positive or negative, depending on the direction of the current. A positive current direction indicates insufficient power generation, requiring an appropriate increase in power generation; in this case, the base compensation power is positive. Conversely, a negative current direction indicates surplus power generation, requiring an appropriate decrease in power generation; in this case, the base compensation power is negative.
[0106] For example, P Prop_pre P represents the predicted drive power. Aux_pre P represents the predicted power of the accessory. Offset P represents the basic compensation power. Gen This represents the total power generation. We can obtain P. Gen =P Prop_pre +P Aux_pre +P Offse .
[0107] In this application, based on the actual current current and current voltage of the power battery, reverse compensation is performed on the power generation to eliminate errors caused by inaccurate efficiency, so that the power generation is as equal as possible to the actual power consumption of the whole vehicle, thereby improving the accuracy of the control method.
[0108] To enable those skilled in the art to better understand this application as a whole, the application process of the solution in this application will be briefly described below with reference to a specific embodiment:
[0109] See Figure 6 This illustrates another flowchart of the vehicle power generation control method in an embodiment of this application, specifically including:
[0110] Step 601: Obtain the current power parameters of the target vehicle in the current cycle.
[0111] The target vehicle is a series hybrid vehicle.
[0112] Step 602: Determine the driving power change parameters of the target vehicle based on the current driving power, the first historical driving power of the target vehicle in the first historical period, and the second historical driving power of the target vehicle in the second historical period.
[0113] Specifically, the difference between the current driving power and the first historical driving power is determined as the first driving power change; the difference between the first historical driving power and the second historical driving power is determined as the second driving power change; and the average of the first driving power change and the second driving power change is used as the driving power change parameter of the target vehicle.
[0114] Step 603: The sum of the driving power change parameters and the current driving power is used as the predicted driving power of the target vehicle in the next cycle.
[0115] Step 604: Determine the accessory power change parameters of the target vehicle based on the current accessory power, the first historical accessory power of the target vehicle in the first historical period, and the second historical accessory power of the target vehicle in the second historical period.
[0116] Specifically, the difference between the current accessory power and the first historical accessory power is determined as the first accessory power change; the difference between the first historical accessory power and the second historical accessory power is determined as the second accessory power change; and the average of the first accessory power change and the second accessory power change is used as the accessory power change parameter of the target vehicle.
[0117] Step 605: The sum of the accessory power change parameters and the current accessory power is used as the predicted accessory power of the target vehicle in the next cycle.
[0118] The first historical cycle is the previous cycle of the current cycle, and the second historical cycle is the previous cycle of the first historical cycle.
[0119] Step 606: Determine the basic compensation power based on the product of the current current and the current voltage of the target vehicle's power battery.
[0120] Step 607: The sum of the predicted drive power, predicted accessory power, and basic compensation power is taken as the total power generation of the target vehicle in the next cycle.
[0121] Step 608: Control the target vehicle's power generation in the next cycle to the total power generation.
[0122] In this application, the actual power consumption in the next cycle can be predicted. By controlling the balance between the power generation and the actual power consumption, the number of charging and discharging cycles of the power battery during driving can be reduced, thereby reducing the overall vehicle energy consumption and extending the service life of the power battery.
