[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] In an exemplary embodiment, Figure 1 As shown, a range extender control method is provided, which can be applied to a processor with signal acquisition, processing, output or control functions, including but not limited to an electronic controller, a domain controller and a regional controller.

[0055] The method is described by taking the application of the method to a battery management system including a range extender controller as an example, and includes the following steps S102 to S110. Among them:

[0056] Step S102, obtaining the fuel consumption data and electric energy change data of the target vehicle in the current mileage cycle, and the charge of the first range extender associated with the target vehicle.

[0057] Among them, the target vehicle may refer to an extended-range electric vehicle.

[0058] Among them, the current mileage cycle may refer to the mileage range in which the total mileage of the target vehicle is located. In actual applications, the mileage of the vehicle can be divided into several mileage cycles, each mileage cycle has a corresponding starting mileage and ending mileage. When the total mileage of the vehicle is between the starting mileage of a mileage cycle and the ending mileage of a mileage cycle, then the mileage cycle is the current mileage cycle of the vehicle.

[0059] The fuel consumption data may refer to data representing the fuel consumption of a vehicle.

[0060] The power change data may refer to data characterizing the power change of the battery of the vehicle. In practical applications, the power change data may include but is not limited to power consumption data and charging data.

[0061] Among them, the first range extender charge may refer to information used to control the working state of the range extender in the current mileage cycle. In actual applications, the first range extender charge may represent data of the range extender startup charge in the current mileage cycle or a preset range extender startup charge initial value. In a specific implementation, when the battery charge of the power battery of the target vehicle is less than the first range extender charge in the current mileage cycle, the range extender controller may control the start-up of the range extender of the target vehicle.

[0062] As an example, the total mileage of an extended-range electric vehicle can be divided into several mileage cycles, each mileage cycle having a corresponding range extender charge (SOC). When the SOC value is reached, the range extender starts to convert chemical energy into electrical energy to ensure the SOC of the target vehicle. In order to determine the range extender charge in each mileage cycle, the range extender controller can obtain the fuel consumption data and electrical energy change data of the target vehicle in the current mileage cycle, as well as the first range extender charge associated with the target vehicle, and then modify the first range extender charge based on the fuel consumption data and electrical energy change data in the current mileage cycle to obtain the range extender charge in the next mileage cycle.

[0063] In a specific implementation, the range extender controller (or battery management system) can obtain fuel consumption data and electric energy change data, etc. through the sensors of the extended-range electric vehicle. Specifically, the sensors of the extended-range electric vehicle can monitor and obtain current data and voltage data of the power battery, and the range extender controller can determine the electric energy change data based on the current data and voltage data, etc. The fuel level sensor of the extended-range electric vehicle can monitor and obtain information such as the fuel level in the fuel tank, and the flow sensor of the extended-range electric vehicle can monitor and obtain information such as the amount of fuel flowing through the fuel pump or fuel injector, and the range extender controller can determine the fuel consumption data based on information such as the fuel level and / or fuel level.

[0064] Step S104, obtaining the charging frequency information of the target vehicle in the current mileage cycle according to the fuel consumption data and the electric energy change data, and obtaining the charge of the second range extender associated with the target vehicle according to the charge of the first range extender and the charging frequency information.

[0065] Among them, the charging frequency information may refer to the information on the degree of influence of the charging operation on the energy consumption and / or power consumption during the driving process of the vehicle. In practical applications, the charging frequency information may be used as a charging convenience index information. The charging frequency information may be expressed as: (charging power / power consumption power)*(power consumption power / (power consumption power+fuel consumption power)). The charging frequency information may be expressed as CCI (Charging Convenience Index).

[0066] Among them, the second range extender charge may refer to data obtained by modifying the first range extender charge based on the charging frequency information. In actual applications, the second range extender charge may be used as the range extender charge in the next mileage cycle.

[0067] As an example, the range extender controller can calculate the charging frequency information of the target vehicle in the current mileage cycle based on the fuel consumption data and the electric energy change data, and modify and adjust the first range extender charge within a preset range of the range extender charge adjustment based on the charging frequency information to obtain the second range extender charge associated with the target vehicle.

[0068] Step S106, based on the fuel consumption data, the electric energy change data and the charging frequency information, the cycle length of the next mileage cycle corresponding to the target vehicle is obtained; the next mileage cycle is a mileage cycle with the mileage at the end of the current mileage cycle as the starting point and the cycle length as the length.

[0069] Among them, the next mileage cycle may refer to the next mileage cycle after the current mileage cycle. In actual applications, the next mileage cycle may include a mileage cycle with the mileage at the end of the current mileage cycle as the starting point and the cycle length of the next mileage cycle as the length.

[0070] The cycle length may refer to the mileage length between the starting mileage and the ending mileage of the mileage cycle. In practical applications, the cycle length may include the difference between the ending mileage and the starting mileage of the mileage cycle.

[0071] As an example, the range extender controller can calculate the adjustment ratio of the mileage cycle based on the fuel consumption data, electric energy change data and charging frequency information in the current mileage cycle, and then the terminal can adjust the initial value S of the mileage cycle length (such as 500km) based on the adjustment ratio, so as to obtain the cycle length of the next mileage cycle corresponding to the target vehicle.

[0072] Step S108: taking the charge amount of the second range extender as the charge amount of the range extender of the target vehicle in the next mileage cycle.

[0073] As an example, after calculating the charge of the second range extender and the cycle length of the next mileage cycle, the range extender controller can use the charge of the second range extender as the range extender charge of the target vehicle in the next mileage cycle. In the next mileage cycle, when the battery charge of the target vehicle is lower than the charge of the second range extender, the range extender of the target vehicle will be started.

[0074] Step S110 , when the battery charge of the target vehicle is less than the charge of the range extender in the next mileage cycle, the range extender of the target vehicle is controlled to start.

[0075] The battery charge may refer to information representing the charge of the power battery of the electric vehicle.

[0076] As an example, when the mileage of the target vehicle is within the next mileage cycle, the range extender controller can obtain the battery charge of the target vehicle's power battery in real time, and the range extender can compare the battery charge with the range extender charge of the target vehicle in the next mileage cycle. When the battery charge is less than the range extender charge, the range extender controller generates a control instruction / control signal, which can be used to control the range extender of the target vehicle to be in a started state. It can be understood that the process of controlling the range extender based on the battery management system can be achieved by the collaborative work of multiple controllers in the battery management system, for example: the domain controller or the vehicle controller VCU can process the control instruction / control signal generated by the range extender controller, and then control the range extender of the target vehicle to be in a started state.

[0077] In the above range extender control method, by obtaining the fuel consumption data and electric energy change data of the target vehicle in the current mileage cycle, and the charge of the first range extender associated with the target vehicle, the charging frequency information of the target vehicle in the current mileage cycle is calculated based on the fuel consumption data and the electric energy change data, and the charge of the second range extender associated with the target vehicle is accurately obtained in combination with the charge of the first range extender and the charging frequency information. At the same time, according to the fuel consumption data and the electric energy change data, the cycle length of the next mileage cycle corresponding to the target vehicle is obtained, and the charge of the second range extender is used as the charge of the range extender of the target vehicle in the next mileage cycle, so that when the battery charge of the target vehicle is less than the charge of the range extender in the next mileage cycle, the start of the range extender of the target vehicle is controlled in time, and the fuel consumption and electric energy change information during the actual driving process of the vehicle can be fully analyzed, and the charge of the range extender in each mileage cycle can be dynamically determined and automatically adjusted to achieve adaptive adjustment of the charge of the range extender, so as to control the working state of the range extender by using the charge of the range extender, thereby improving the control accuracy of the range extender.

[0078] In an exemplary embodiment, the electric energy change data includes charging electric energy data and electric energy consumption data. According to the fuel consumption data and the electric energy change data, the charging frequency information of the target vehicle in the current mileage cycle is obtained, including: determining the converted electric energy data corresponding to the fuel consumption data according to the fuel consumption data and the preset oil-to-electric conversion information; determining the first proportion information according to the ratio between the charging electric energy data and the electric energy consumption data; determining the second proportion information according to the converted electric energy and the electric energy consumption data; and determining the charging frequency information according to the product of the first proportion information and the second proportion information.

[0079] The charging power data may refer to the data representing the amount of power obtained by the vehicle from external devices (such as charging piles, etc.) during the current mileage cycle. In practical applications, the charging power data may be expressed as E 充 .

[0080] The power consumption data may refer to data representing the amount of power consumed by the vehicle in the current mileage cycle. In practical applications, the power consumption data may be expressed as E 电 .

[0081] Among them, the preset oil-to-electricity conversion information may refer to pre-set information used to characterize the conversion relationship between fuel consumption data and electric energy data. In actual applications, the preset oil-to-electricity conversion information may include the average value of the oil-to-electricity conversion coefficient of a vehicle traveling in an extended-range mode in a Worldwide Harmonized Light Vehicles Test Cycles (WLTC) operating cycle.

[0082] The first ratio information may refer to information representing the ratio between the charging power data and the power consumption power data.

[0083] The second ratio information may refer to information representing the ratio between the converted electric energy and the electric energy consumption data. In practical applications, the second ratio information may be expressed as converted electric energy / (converted electric energy+electric energy consumption data).

[0084] As an example, the range extender controller can convert the fuel consumption data into corresponding electric energy data according to the fuel consumption data in the current mileage cycle and the preset oil-to-electric conversion information, and obtain the converted electric energy data E corresponding to the fuel consumption data. 油 , and then the range extender controller can determine the first proportion information according to the ratio between the charging power energy data and the power consumption power energy data. The range extender controller can also determine the second proportion information according to the converted power and the power consumption power data. For example, the range extender controller can calculate the sum of the converted power and the power consumption power data to obtain the total energy consumption data, and then calculate the ratio between the converted power and the total energy consumption data to obtain the second proportion information. The range extender controller can determine the charging frequency information according to the product of the first proportion information and the second proportion information.

[0085] In this embodiment, by determining the converted electric energy data corresponding to the fuel consumption data according to the fuel consumption data and the preset oil-to-electric conversion information; determining the first proportion information according to the ratio between the charging electric energy data and the electric energy consumption data; determining the second proportion information according to the converted electric energy and the electric energy consumption data; and determining the charging frequency information according to the product of the first proportion information and the second proportion information, it is possible to obtain accurate first proportion information based on the ratio between the charging electric energy data and the electric energy consumption data, and obtain accurate second proportion information based on the converted electric energy data and the electric energy consumption data corresponding to the fuel consumption data, so as to accurately calculate the charging frequency information based on the first proportion information and the second proportion information, and provide a data basis for the subsequent determination / adjustment of the charge of the range extender based on the charging frequency information, so as to accurately control the working state of the range extender based on the charge of the range extender, thereby improving the control accuracy of the range extender.

[0086] In some embodiments, obtaining a charge amount of a second range extender associated with a target vehicle based on the charge amount of a first range extender and the charging frequency information includes: determining adjustment amplitude information based on a ratio between a difference between the charging frequency information and preset charging frequency reference information and the preset charging frequency reference information; obtaining a preset step length, and adjusting the charge amount of the first range extender based on the adjustment amplitude information and the preset step length to obtain the charge amount of the second range extender.

[0087] Among them, the preset charging frequency reference information may refer to pre-set information used to determine whether the charging frequency information meets the preset frequency information requirements. In actual applications, the preset charging frequency reference information may include the charging frequency information of the target vehicle under preset test conditions (such as mileage, driving time, number of charging times, etc.).

[0088] The adjustment amplitude information may refer to information used to adjust / modify the charge of the first range extender.

[0089] The preset step size may refer to a single adjustment / modification value when adjusting / modifying the charge of the first range extender. In practical applications, the preset step size may include a range extender charge adjustment threshold SOC deta The preset step size may include but is not limited to 5%.

[0090] As an example, the range extender controller can calculate the difference between the charging frequency information and the preset charging frequency reference information, and calculate the ratio between the difference and the preset charging frequency reference information. The difference between the charging frequency information and the preset charging frequency reference information and the ratio between the preset charging frequency reference information can characterize the degree of difference between the charging frequency information and the preset charging frequency reference information in the current mileage cycle. In practical applications, the charging frequency information is compared with the preset charging frequency reference information. For every 5% increase in the charging frequency information, the range extender controller can adjust the charge of the first range extender according to the preset step length. The difference between the charging frequency information and the preset charging frequency reference information and the ratio between the preset charging frequency reference information can be used as adjustment amplitude information. The range extender controller can adjust the charge of the first range extender according to the adjustment amplitude information and the preset step length to obtain the charge of the second range extender.

[0091] In this embodiment, the adjustment amplitude information is determined according to the ratio of the difference between the charging frequency information and the preset charging frequency reference information to the preset charging frequency reference information; the preset step length is obtained, and the charge of the first range extender is adjusted according to the adjustment amplitude information and the preset step length to obtain the charge of the second range extender. The difference between the charging frequency information and the preset charging frequency information can be analyzed, and the charge of the first range extender can be accurately and reasonably adjusted according to the preset step length to obtain the accurate charge of the second range extender, so as to use the charge of the second range extender to control the working state of the range extender, thereby improving the control accuracy of the range extender.

[0092] In some embodiments, the electric energy change data includes charging electric energy data and electric energy consumption data. According to the fuel consumption data, the electric energy change data and the charging frequency information, the cycle length of the next mileage cycle corresponding to the target vehicle is obtained, including: determining the first adjustment information according to the charging electric energy data, the electric energy consumption data and the electric mileage data of the target vehicle in the current mileage cycle; determining the converted electric energy data corresponding to the fuel consumption data according to the fuel consumption data and the preset oil-to-electric conversion information; determining the second adjustment information according to the converted electric energy data, the fuel mileage data, the electric energy consumption data and the electric mileage data of the target vehicle in the current mileage cycle; determining the third adjustment information according to the converted electric energy data, the fuel mileage data, the electric energy consumption data, the electric mileage data and the charging frequency information; adjusting the preset mileage cycle initial value according to the first adjustment information, the second adjustment information and the third adjustment information to obtain the cycle length of the next mileage cycle.

[0094] The first adjustment information may refer to information used to calculate the cycle length of the next mileage cycle.

[0095] The fuel mileage data may refer to data representing the distance traveled by the vehicle on the vehicle battery. In practical applications, the fuel mileage may be expressed as S 油 .

[0096] The second adjustment information may refer to information used to calculate the cycle length of the next mileage cycle.

[0097] The third adjustment information may refer to information used to calculate the cycle length of the next mileage cycle.

[0098] As an example, the range extender controller can calculate the first adjustment information based on the charging power data, the power consumption data and the electric mileage data of the target vehicle in the current mileage cycle. The range extender controller can also calculate the converted power data corresponding to the fuel consumption data based on the fuel consumption data and the preset fuel-to-electric conversion information, and then calculate the second adjustment information based on the converted power data, the fuel mileage data, the power consumption data and the electric mileage data of the target vehicle in the current mileage cycle. The range extender controller can determine the third adjustment information based on the converted power data, the fuel mileage data, the power consumption data, the electric mileage data and the charging frequency information. After obtaining the first adjustment information, the second adjustment information and the third adjustment information, the range extender controller can adjust the preset mileage cycle initial value according to the first adjustment information, the second adjustment information and the third adjustment information, so as to determine the cycle length of the next mileage cycle corresponding to the target vehicle.

[0099] In this embodiment, the first adjustment information is determined according to the charging electric energy data, the electric energy consumption data and the electric mileage data of the target vehicle in the current mileage cycle; the converted electric energy data corresponding to the fuel consumption data is determined according to the fuel consumption data and the preset fuel-to-electric conversion information; the second adjustment information is determined according to the converted electric energy data, the fuel mileage data, the electric energy consumption data and the electric mileage data of the target vehicle in the current mileage cycle; the third adjustment information is determined according to the converted electric energy data, the fuel mileage data, the electric energy consumption data, the electric mileage data and the charging frequency information; the preset mileage cycle initial value is adjusted according to the first adjustment information, the second adjustment information and the third adjustment information. The cycle length of the next mileage cycle can be obtained by adjusting the charging power data, the power consumption data and the electric mileage of the target vehicle in the current mileage cycle, and accurate first adjustment information can be obtained based on the charging power data, the power consumption data and the electric mileage of the target vehicle in the current mileage cycle, and accurate second adjustment information can be obtained based on the fuel consumption data, fuel mileage, power consumption data and electric mileage of the target vehicle in the current mileage cycle, and accurate third adjustment information can be obtained based on the converted power data, fuel mileage data, power consumption data, electric mileage data and charging frequency information, so as to subsequently determine the cycle length of the next mileage cycle corresponding to the target vehicle based on the first adjustment information, the second adjustment information and the third adjustment information, thereby improving the accuracy of the cycle length.

[0100] In some embodiments, first adjustment information is determined based on charging power data, power consumption power data, and the target vehicle's electric mileage data in the current mileage cycle, including: determining charging efficiency information based on the ratio between the charging power data and the power consumption power data; determining power consumption efficiency information based on the ratio between the power consumption power data and the electric mileage data; determining the first adjustment information based on the ratio between the charging efficiency information and the power consumption efficiency information.

[0101] The charging efficiency information may refer to information characterizing the proportional relationship between the charge amount and the power consumption of the vehicle. In practical applications, the charging efficiency information may include the ratio between the charging power data and the power consumption power data.

[0102] The power consumption efficiency information may refer to information characterizing the power consumption of a vehicle per unit mileage. In practical applications, the power consumption efficiency information may include a ratio between power consumption data and power mileage.

[0103] As an example, the range extender controller can calculate the charging efficiency information based on the ratio between the charging power energy data and the power consumption power data. The range extender controller can also calculate the power consumption efficiency information based on the ratio between the power consumption power data and the electric mileage data. Then the range extender controller can calculate the first adjustment information based on the ratio between the charging efficiency information and the power consumption efficiency information. In actual applications, the first adjustment information can be used to ensure that the power consumption efficiency information is less than or equal to the charging efficiency information. Therefore, the first adjustment information can be determined by the ratio between the charging efficiency information and the power consumption efficiency information.

Based on the charging power energy data, the power consumption power data and the power mileage data, accurate charging efficiency information and power consumption efficiency information can be obtained, so that the first adjustment information is calculated using the charging efficiency information and the power consumption efficiency information, the accuracy of the first adjustment information is improved, and a data basis is provided for subsequently determining the cycle length of the next mileage cycle corresponding to the target vehicle based on the first adjustment information, the second adjustment information and the third adjustment information, thereby improving the accuracy of the cycle length.

[0105] In some embodiments, second adjustment information is determined based on the converted electric energy data, the fuel mileage data, the electric energy consumption data and the electric mileage data of the target vehicle in the current mileage cycle, including: determining the fuel consumption efficiency information based on the ratio between the converted electric energy data and the fuel mileage data; determining the electric consumption efficiency information based on the ratio between the electric energy consumption data and the electric mileage data; determining the second adjustment information based on the ratio between the fuel consumption efficiency information and the electric consumption efficiency information.

[0106] The fuel efficiency information may refer to information representing the amount of fuel consumed per unit mileage of the vehicle.

[0107] The power consumption efficiency information may refer to information characterizing the power consumption of a vehicle per unit mileage. In practical applications, the power consumption efficiency information may include a ratio between power consumption data and power mileage.

[0108] As an example, the range extender controller can calculate the fuel consumption efficiency information based on the ratio between the converted electric energy data and the fuel mileage. The range extender controller can also calculate the power consumption efficiency information based on the ratio between the electric energy data and the electric mileage. Then the range extender controller can determine the second adjustment information based on the ratio between the fuel consumption efficiency information and the power consumption efficiency information. In actual applications, the second adjustment information can be used to ensure that the fuel consumption efficiency information is less than or equal to the power consumption efficiency information.

[0109] In this embodiment, the fuel consumption efficiency information is determined according to the ratio between the converted electric energy data and the oil mileage; the electric energy efficiency information is determined according to the ratio between the electric energy data and the electric mileage; and the second adjustment information is determined according to the ratio between the fuel consumption efficiency information and the electric energy efficiency information. Based on the converted electric energy data, the oil mileage and the electric mileage, accurate fuel consumption efficiency information and electric energy efficiency information can be obtained, so that the second adjustment information is calculated based on the fuel consumption efficiency information and the electric energy efficiency information, and the accuracy of the second adjustment information is improved. This provides a data basis for subsequently determining the cycle length of the next mileage cycle corresponding to the target vehicle based on the first adjustment information, the second adjustment information and the third adjustment information, thereby improving the accuracy of the cycle length.

[0110] In some embodiments, the third adjustment information is determined based on the converted electric energy data, fuel mileage data, electric energy consumption data, electric mileage data and charging frequency information, including: determining the fuel consumption efficiency information based on the ratio between the converted electric energy data and the fuel mileage data; determining the electric energy consumption efficiency information based on the ratio between the electric energy consumption data and the electric mileage data; determining the efficiency difference information based on the difference between the fuel consumption efficiency information and the electric energy consumption efficiency information; obtaining the preset fuel-to-electricity ratio information, the adjustment information corresponding to the current mileage cycle and the fuel-to-electricity ratio information; determining the ratio information based on the ratio between the preset fuel-to-electricity ratio information and the fuel-to-electricity ratio information corresponding to the current mileage cycle; determining the product information based on the product of the sum of the efficiency difference information and the charging frequency information and the first ratio information; determining the third adjustment information based on the sum of the adjustment information corresponding to the current mileage cycle and the product information.

[0111] The efficiency difference information may refer to information representing the difference between the consumption efficiency of fuel energy and electric energy per unit mileage.

[0112] The preset fuel-electricity ratio information may refer to information preset to characterize the ideal ratio between the consumption efficiency of fuel energy and electric energy. In practical applications, the preset fuel-electricity ratio information may be based on the preset fuel consumption data E 油0 , preset fuel consumption mileage data S 油0 , preset power consumption data E 电0 and preset electric mileage data S 电0 Calculated, for example: the preset fuel-electric ratio information can be expressed as: ((preset fuel consumption data E 油0 * Oil-electric conversion information) / preset fuel mileage data S 油0 ) / (Preset power consumption data E 电0 / Preset electric mileage dataS 电0 ), where the preset fuel consumption data E油0 , preset fuel consumption mileage data S 油0 , preset power consumption data E 电0 and preset electric mileage data S 电0 It can be obtained by taking the average value of the fuel consumption data, fuel mileage data, electrical energy consumption data and electrical mileage data of the target vehicle under preset test conditions (such as mileage, driving time, number of charging times, etc.).

[0113] The adjustment information corresponding to the current mileage cycle may refer to information used to calculate the cycle length of the current mileage cycle. Figure 2 As shown, a schematic diagram of obtaining the cycle length is provided, with 3 mileage cycles T t-1 , T t and T t+1 For example, the range extender controller can obtain the target vehicle in the mileage cycle T t-1 (such as the previous mileage cycle) and other information, and by analyzing the fuel consumption and power consumption information, determine the mileage cycle T t (such as the current mileage cycle) adjustment information K t-1 The range extender controller can adjust the information K based on t-1 Adjust the initial value of the mileage cycle to obtain the mileage cycle T t The cycle length, at this time, adjust the information K t-1 Can be used as mileage cycle T t The corresponding adjustment information is similarly based on the target car’s mileage cycle T t The fuel consumption and power consumption in the period are determined to determine the mileage period T t+1 (such as the adjustment information of the next mileage cycle) K t , the adjustment information K t Can be used as mileage cycle T t+1 The corresponding adjustment information.

[0114] As an example, the range extender controller can determine the fuel consumption efficiency information based on the ratio between the converted electric energy data and the fuel mileage data. The range extender controller can determine the power consumption efficiency information based on the ratio between the power consumption electric energy data and the power mileage data. Then the range extender controller can first determine the efficiency difference information based on the difference between the fuel consumption efficiency information and the power consumption efficiency information, and obtain the preset fuel-to-electricity ratio information, the adjustment information corresponding to the current mileage cycle, and the fuel-to-electricity ratio information. Then the range extender controller can determine the ratio information based on the ratio between the preset fuel-to-electricity ratio information and the fuel-to-electricity ratio information corresponding to the current mileage cycle, and determine the product information based on the product between the sum of the efficiency difference information and the charging frequency information and the first ratio information. Then the range extender controller can determine the third adjustment information based on the sum of the adjustment information corresponding to the current mileage cycle and the product information.

[0115] In this embodiment, accurate third adjustment information is obtained based on preset oil-to-electricity ratio information, fuel consumption and power consumption of the current mileage cycle, and charging frequency information, so as to provide a data basis for subsequently determining the cycle length of the next mileage cycle corresponding to the target vehicle based on the first adjustment information, the second adjustment information, and the third adjustment information, thereby improving the accuracy of the cycle length.

[0116] In some embodiments, the preset mileage cycle initial value is adjusted according to the first adjustment information, the second adjustment information and the third adjustment information, including: when the first adjustment information is less than the second adjustment information and less than the third adjustment information, the preset mileage cycle initial value is adjusted according to the first adjustment information; when the second adjustment information is less than the first adjustment information and less than the third adjustment information, the preset mileage cycle initial value is adjusted according to the second adjustment information; when the third adjustment information is less than the first adjustment information and less than the second adjustment information, the preset mileage cycle initial value is adjusted according to the third adjustment information.

[0117] The preset mileage cycle initial value may refer to a preset initial length of the mileage cycle. In practical applications, the mileage cycle initial value may be expressed as S, and the mileage cycle initial value may include but is not limited to 500 km.

[0118] As an example, the first adjustment information K1, the second adjustment information K2 and the third adjustment information K3 can be used as adjustment coefficients of the initial value of the mileage cycle. The range extender controller can compare the size relationship between the first adjustment information, the second adjustment information and the third adjustment information to determine the final coefficient K. The final coefficient K can take the minimum value of K1, K2 and K3, that is, K=min(K1, K2, K3). For example: when the first adjustment information is less than the second adjustment information and less than the third adjustment information, the range extender controller can use the first adjustment information as the final coefficient, adjust the preset initial value of the mileage cycle according to the final coefficient, and obtain the cycle length of the next mileage cycle corresponding to the target vehicle; when the second adjustment information is less than the first adjustment information and less than the third adjustment information, the range extender controller can use the second adjustment information as the final coefficient, adjust the preset initial value of the mileage cycle according to the final coefficient, and obtain the cycle length of the next mileage cycle corresponding to the target vehicle; when the third adjustment information is less than the first adjustment information and less than the second adjustment information, the range extender controller can use the third adjustment information as the final coefficient, adjust the preset initial value of the mileage cycle according to the final coefficient, and obtain the cycle length of the next mileage cycle corresponding to the target vehicle.

[0119] In this embodiment, when the first adjustment information is less than the second adjustment information and less than the third adjustment information, the preset mileage cycle initial value is adjusted according to the first adjustment information; when the second adjustment information is less than the first adjustment information and less than the third adjustment information, the preset mileage cycle initial value is adjusted according to the second adjustment information; when the third adjustment information is less than the first adjustment information and less than the second adjustment information, the preset mileage cycle initial value is adjusted according to the third adjustment information. Based on the size relationship between the first adjustment information and the second adjustment information, the corresponding adjustment information can be flexibly selected to adjust the mileage cycle initial value, so as to obtain the accurate cycle length of the next mileage cycle and improve the accuracy of the cycle length of the next mileage cycle.

[0120] In some embodiments, Figure 3 As shown in the figure, a flow chart of controlling the range extender is provided. When the target vehicle leaves the factory, the range extender charge (i.e., the range extender SOC) can be preset to 30%, and the adjustment period of the range extender charge (i.e., the mileage period) is set as S, where S=500km*coefficient K, and the factory value of K is 1. K is then recalculated after each mileage period S. The range extender controller can count the fuel consumption (e.g., fuel consumption data) of the target vehicle during driving, and convert the fuel consumption into corresponding electrical energy (i.e., the converted electrical energy data E after multiplying the fuel consumption by the fuel-to-electricity conversion coefficient) 油 ), the range extender controller can also obtain the fuel mileage S of the target vehicle during driving. 油 , power consumption data E 电, Electric driving mileage S 电 And charging energy data E 充 , among which, fuel consumption data, fuel mileage S 油 , power consumption data E 电 , Electric driving mileage S 电 And charging energy data E 充 When entering the next mileage cycle, it is reset to "0" and the calculation starts again. The oil-to-electric conversion coefficient information can be taken as the average oil-to-electric conversion coefficient of a WLTC operating cycle in the extended range mode. Set the range of the range extender charge change to [20%, 80%], and the threshold of the single change of the range extender charge (i.e. the preset step length) is the range extender charge adjustment threshold SOC deta , such as 5%, the total power of the power battery at full charge (i.e. the power battery at full charge) is recorded as E batt .

[0121] The range extender controller can be set to adjust the range extender charge immediately after the following conditions are met (without the need to reach S mileage): At the end of a mileage cycle, the range extender controller can adjust the charge of the range extender based on the converted electric energy data E corresponding to the mileage cycle. 油 , power consumption data E 电 and charging energy data E 充 , calculate the charging frequency information CCI, the calculation expression of the charging frequency information CCI can be expressed as CCI= (E 充 / E 电 )*(E 电 / (E 电 +E 油 )), where (E 充 / E 电 ) can be used as the first proportion information, which can represent the proportion of the power obtained by the car from the charging pile to the total power consumption. The higher this proportion is, the better the convenience of charging is, because the vehicle can rely more on external charging rather than its own power consumption; E 电 / (E 电 +E 油 ) can be used as the second ratio information, which can represent the ratio of power consumption to total energy consumption. The higher the ratio, the more the vehicle relies on electricity rather than gasoline in energy consumption, thus reflecting the importance of charging convenience in reducing oil dependence. The range extender controller can compare the charging frequency information CCI of the previous mileage cycle with the preset charging frequency reference information CCI 0 Compare and determine the charging frequency information CCI of the previous mileage cycle and the preset charging frequency reference information CCI 0The difference between the charging frequency information and the preset charging frequency reference information can be used to adjust the charge of the first range extender. The range extender controller can adjust the threshold SOC according to the charge of the range extender for every 5% increase in the charging frequency information. deta The charge of the first range extender (such as the charge of the range extender corresponding to the previous mileage cycle) is adjusted to obtain the charge of the range extender for the next mileage cycle corresponding to the previous mileage cycle (i.e., the charge of the second range extender). In the specific implementation, for every 5% increase in the charging frequency information, the charge of the first range extender can be reduced by 1 times the range extender charge adjustment threshold SOC deta On the contrary, for every 5% decrease in the charging frequency information, the charge of the first range extender can be increased by 1 times the range extender charge adjustment threshold SOC deta Therefore, the range extender charge SOC for the next mileage cycle is 下周期 Compared with the range extender charge SOC of the previous mileage cycle 上周期 The relationship between can be expressed as:

[0122] .

[0123] Wherein, ROUND may indicate rounding to the nearest integer. Preset charging frequency reference information CCI 0 The test conditions can be designed based on the vehicle driving 50 km per day, driving 5 times a week, and charging on the 3rd and Friday of each week. The test conditions are designed to be 50 km per day, driving 5 days from Monday to Friday, and fully charging after the trip on the 3rd and Friday of each week. A total of 100 vehicles, distributed in different regions, run under this condition for one week, calculate the CCI respectively, and then take the average value of each CCI as the preset charging frequency reference information CCI 0 .

[0124] It can be understood that the length of each mileage cycle can be calculated based on the parameters in the previous mileage cycle (such as vehicle energy consumption information, etc.). Specifically, after each mileage cycle S is reached, the range extender controller can calculate the charging energy data E in the previous mileage cycle. 充 , power consumption data E 电 , Electric driving mileage S 电 , converted electric energy data E 油 and gas mileage 油To calculate K for this mileage cycle, the K value will no longer change in this mileage cycle. The calculation of the adjustment coefficient K requires analysis of the vehicle's energy efficiency and charging efficiency. The adjustment coefficient K can be obtained from the first adjustment information K1, the second adjustment information K2, and the third adjustment information. Assuming that in the next mileage cycle, the vehicle can use energy more efficiently, that is, increase the proportion of electricity use and reduce the proportion of oil use, the range extender controller can first calculate the power consumption efficiency information (such as power consumption rate) and fuel consumption efficiency information (such as fuel consumption rate) in the previous mileage cycle, wherein the power consumption efficiency information can be the ratio between the power consumption data and the mileage driven by electricity, and the fuel consumption efficiency information can be the ratio between the converted power data and the mileage driven by oil. The calculation of the first adjustment information K1 can also consider the charging efficiency of the charging pile (such as charging efficiency information), and the charging efficiency information can be the ratio between the charging power data and the power consumption data (that is, the ratio of the charging amount of the charging pile to the power consumption). In order to improve the energy efficiency, the proportion of electricity use is increased in the next mileage cycle, so a target power consumption rate can be set, which can be expressed as K*E 电 / S 电 , the vehicle operation needs to ensure that the target power consumption rate is less than or equal to the power consumption efficiency information, and the charging efficiency information also needs to be considered at the same time. At this time, the relationship between the target power consumption rate, power consumption efficiency information and charging efficiency information can be expressed as: K*E 电 / S 电 ≤E 充 / E 电 Therefore, the calculation expression of the adjustment coefficient K (or the first adjustment information K1) can be expressed as:

[0125] .

[0126] In order to ensure that the adjustment coefficient K is a reasonable value, the fuel consumption rate also needs to be considered to ensure that the adjusted mileage cycle does not lead to an excessively high fuel consumption rate. Therefore, a target fuel consumption rate is set, which can be used as an upper limit value (such as not exceeding a certain proportion of the current fuel consumption efficiency information). At this time, the calculation expression of the adjustment coefficient K (or the second adjustment information K2) can be expressed as:

[0127] .

[0128] At the same time, the adjustment coefficient K may also be determined by considering the adjustment coefficient corresponding to the historical mileage cycle. Specifically, the range extender controller may determine the adjustment coefficient (or the third adjustment information K3) based on the converted electric energy data, fuel mileage data, electric energy consumption data, electric mileage data and charging frequency information in the current mileage cycle. At this time, the calculation expression of the adjustment coefficient K (or the third adjustment information K3) may be expressed as:

[0129] .

[0130] Among them, K prev can be the adjustment information corresponding to the current mileage cycle (such as the adjustment information K of the previous mileage cycle), λ can be used as an adjustment parameter, and λ can be used to control the degree of influence on K, E 油 / S 油 -E 电 / S 电 It can characterize the difference between the consumption efficiency of oil energy and electric energy per unit mileage. If oil consumption is more efficient than electric energy, K increases, otherwise it decreases. The introduction of charging frequency information CCI can consider the influence of charging frequency / charging convenience in the process of determining the adjustment coefficient K. The charging frequency information CCI can reflect the convenience and dependence of charging. If charging is very convenient and most of the energy consumption comes from electric energy, CCI will be larger and K will increase, because this can make better use of electric energy and reduce oil consumption.

[0131] Among them, λ can be expressed as P 0 / P, where the calculation expression of can be expressed as:

[0132] .

[0133] Among them, the preset fuel consumption data E 油0 , preset fuel consumption mileage data S 油0 , preset power consumption data E 电0 and preset electric mileage data S 电0 It can be obtained by acquiring the fuel consumption data, fuel mileage data, electrical energy consumption data and electrical mileage data of the target vehicle under preset test conditions (such as mileage, driving time, number of charging times, etc.).

[0134] The calculation expression of P can be expressed as:

[0135] .

[0136] Finally, K can take the minimum value of K1, K2 and K3, K=min(K1, K2, K3). At this time, the calculation expression of the adjustment coefficient K can be expressed as:

[0137] .

[0138] The range extender controller can use the coefficient K to adjust the preset initial value of the mileage cycle, and can obtain the cycle length of the next cycle. The terminal uses the charge of the second range extender as the range extender charge of the target vehicle in the next mileage cycle, thereby accurately obtaining the cycle length and range extender charge of the next mileage cycle based on the vehicle driving conditions in the current mileage cycle, and adaptively adjusting the range extender charge so as to accurately control the working state of the range extender based on the range extender charge of each mileage cycle, thereby improving the control accuracy of the range extender.

[0139] In this embodiment, by counting the vehicle's oil and electricity consumption, the startup SOC of the range extender is adaptively adjusted, and the learning cycle is dynamically adjusted to achieve rapid adaptive adjustment. The startup SOC of the range extender can be automatically adjusted according to the user's electricity and oil consumption, and the change cycle can be dynamically adjusted according to the user, so that the startup SOC of the range extender can be adjusted faster, thereby accelerating the vehicle's adaptive ability and improving the user experience.
