[0002] With the widespread use of vehicles, the comprehensive average energy consumption of automobiles has become an important research direction. The so-called comprehensive average energy consumption refers to the average energy consumption corresponding to the current total mileage of the vehicle, which will continue to change with the increase of the total mileage. In the prior art, when determining the comprehensive average energy consumption of a vehicle, a standard energy consumption is generally measured through an energy consumption test method, and a weight value is assigned to the standard energy consumption and the actual average energy consumption of the historical mileage, so as to determine the comprehensive average energy consumption.

[0003] However, the weight value of the above-mentioned method for determining the comprehensive average energy consumption is fixed, and the actual driving process of the vehicle involves different working conditions.

[0086] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described in the text are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0087] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0088] In order to solve the technical problem that the comprehensive average energy consumption obtained by the method for determining the comprehensive average energy consumption in the prior art is inaccurate, which affects the user experience, the present application provides a method and device for determining the average energy consumption of a vehicle, which can dynamically adjust the weight value of the standard energy consumption of the vehicle by referring to the historical environmental parameters involved in the historical driving process of the vehicle and the historical air-conditioning operating parameters of the vehicle, thereby performing weighted summation of the standard energy consumption and the historical actual energy consumption to determine the comprehensive average energy consumption of the vehicle. Since the weight value of the standard energy consumption is dynamically determined from multiple aspects such as the total mileage of the vehicle, historical environmental parameters, and historical air-conditioning operating parameters, it is more in line with different operating conditions of the vehicle, so that the determined comprehensive average energy consumption is more accurate, thereby improving the accuracy of determining the average energy consumption of the vehicle and enhancing the user experience.

[0089] The method for determining the average energy consumption of a vehicle provided in the present application is further explained below with reference to specific embodiments in conjunction with the accompanying drawings. The embodiments do not constitute a limitation on the embodiments of the present invention.

[0090] join Figure 1 , is a flow chart of an embodiment of a method for determining average energy consumption of a vehicle provided in an embodiment of the present application. Figure 1 As shown, the process may include the following steps:

[0091] Step 101: determine the total mileage and standard energy consumption of the vehicle at the current moment, and obtain the historical actual average energy consumption.

[0092] The above total mileage refers to the total mileage travelled by the vehicle from the time it leaves the factory to the current moment.

[0093] The above-mentioned standard energy consumption refers to the standard energy consumption of the vehicle from leaving the factory to the present moment measured by the operating condition energy consumption test method (such as the CLTC operating condition energy consumption test). It is the measured energy consumption, not the actually recorded energy consumption.

[0094] The above-mentioned historical actual average energy consumption refers to the actual average energy consumption of the vehicle during the historical driving process. The historical driving process can be a preset historical time period (for example, within the last week) or the historical mileage of the vehicle (for example, within the last 1000 km of driving). The embodiment of the present application does not impose any restrictions on this.

[0095] Among them, if the above historical driving process is a preset historical time period, then the historical actual average energy consumption is the total energy consumption of the vehicle in the historical time period divided by the total mileage of the vehicle in the historical time period.

[0096] If the above historical driving process is a preset historical mileage, then the historical actual average energy consumption is the energy consumption within the historical mileage divided by the historical mileage.

[0097] In the embodiment of the present application, the execution subject of the embodiment of the present application may be a vehicle, and further, may be a controller installed in the vehicle. When the execution subject of the embodiment of the present application needs to determine the average energy consumption of the vehicle, the three parameters corresponding to the vehicle at present may be obtained first, so as to subsequently determine the average energy consumption corresponding to the vehicle at the current moment based on the three parameters. The above average energy consumption refers to the comprehensive average energy consumption corresponding to the vehicle at the current moment, which is the average energy consumption based on the total mileage currently traveled by the vehicle.

[0098] Furthermore, the above three parameters may be the total mileage and standard energy consumption of the vehicle at the current moment, and the historical actual average energy consumption.

[0099] As an exemplary implementation, the total mileage of the vehicle can be recorded in real time while the vehicle is driving. Therefore, the execution subject of the embodiment of the present application can directly obtain the total mileage of the vehicle at the current moment from the vehicle's record.

[0100] As an exemplary implementation, the executing entity of the embodiment of the present application may use a preset operating condition energy consumption test (such as a CLTC operating condition energy consumption test) to perform an operating condition energy consumption test on the vehicle to obtain the standard energy consumption of the vehicle at the current moment.

[0101] As an exemplary implementation, when obtaining the historical actual average energy consumption, the historical mileage closest to the current moment (hereinafter referred to as the second historical mileage for ease of description) may be determined, and the historical actual average energy consumption corresponding to the second historical mileage may be obtained.

[0102] When there are multiple second historical mileages, the multiple second historical mileages determined may be different historical mileages, such as the last 50 km, the last 100 km, and the last 500 km of the vehicle. Based on this, the average value, maximum value, or minimum value of the multiple historical actual average energy consumptions may be used as the historical actual average energy consumption corresponding to the vehicle.

[0103] As another exemplary embodiment, during driving, the vehicle may record the vehicle's driving style, driving conditions, and corresponding actual average energy consumption information in real time or at regular intervals. The driving style may include parameters such as the vehicle's driving mode and driving speed, and the driving conditions may include parameters such as the road conditions and weather conditions on which the vehicle is traveling.

[0104] Based on this, as an optional implementation method, when obtaining the historical actual average energy consumption, the current driving style of the vehicle can be determined.

[0105] Thereafter, it may be determined from the history records of the vehicle based on the driving style whether there is a target history record including the driving style.

[0106] Optionally, when the target historical record exists, the historical actual average energy consumption corresponding to the target historical record may be determined as the historical actual average energy consumption corresponding to the current vehicle.

[0107] As another optional implementation, when obtaining the historical actual average energy consumption, the current driving condition of the vehicle may be determined.

[0108] Afterwards, it may be determined from the historical records of the vehicle based on the driving condition whether there is a target historical record that includes the driving condition.

[0109] Optionally, when the target historical record exists, the historical actual average energy consumption corresponding to the target historical record may be determined as the historical actual average energy consumption corresponding to the current vehicle.

[0110] As another optional implementation, when obtaining the historical actual average energy consumption, the current driving style and current driving conditions of the vehicle may be determined.

[0111] Afterwards, based on the driving style and the driving condition, it may be determined from the historical records of the vehicle whether there is a target historical record including the driving style and the driving condition.

[0112] When it is determined that the target historical record exists, the historical actual average energy consumption corresponding to the target historical record may be determined as the historical actual average energy consumption corresponding to the current vehicle.

[0113] Step 102: Determine an initial weight value corresponding to the standard energy consumption according to the total mileage.

[0114] The above initial weight value refers to the weight value corresponding to the standard energy consumption of the vehicle when determining the current average energy consumption of the vehicle.

[0115] In the embodiment of the present application, the initial weight value is not fixed, and it can change continuously according to the total mileage of the vehicle. In practical applications, as the vehicle continues to travel, the speed of the vehicle can change continuously according to the driving needs of the user. The more mileage the vehicle travels, the greater the difference from the standard speed of the vehicle (the standard speed set at the factory). Therefore, the greater the total mileage of the vehicle, the lower the weight of its standard energy consumption. In other words, the initial weight value is negatively correlated with the total mileage of the vehicle.

[0116] Based on this, in one embodiment, when determining the initial weight value corresponding to the standard energy consumption, the execution subject of the embodiment of the present application may obtain at least one adjustment parameter, and input at least one of the adjustment parameters and the above-mentioned total mileage into a preset adjustment formula, thereby obtaining the initial weight value corresponding to the standard energy consumption. The above-mentioned adjustment parameter may be a parameter in the adjustment formula, and the adjustment formula represents that the initial weight value is negatively correlated with the total mileage.

[0117] As an optional implementation, the above adjustment parameters may include a first adjustment parameter and a second adjustment parameter. Based on this, when at least one adjustment parameter and the total mileage are input into a preset adjustment formula to obtain an initial weight corresponding to the standard energy consumption, the first adjustment parameter, the second adjustment parameter, and the total mileage may be input into the following formula (I) to obtain an initial weight value corresponding to the standard energy consumption:

[0118] K0=k1*(LS) / L+k2*((LS) / L) 2 Formula (I)

[0119] Among them, the above K0 is the initial weight value, the above k1 is the first adjustment parameter, the above k2 is the second adjustment parameter, the above S is the total mileage, and the above L is a preset mileage threshold, wherein the total mileage is less than or equal to the mileage threshold.

[0120] Furthermore, the mileage threshold may be the maximum mileage value set for the vehicle when it leaves the factory, such as 10,000 km. When the vehicle reaches the mileage threshold, it will no longer continue to travel. The first adjustment parameter and the second adjustment parameter may be 0.5 and 0.4, respectively, which are obtained through driving tests under normal temperature urban conditions. It can be understood that the first adjustment parameter and the second adjustment parameter may also be other values, and the embodiments of the present application do not impose any limitation on this.

[0121] Step 103: Determine historical environmental parameters of the vehicle within a preset first historical mileage and historical air conditioning operating parameters of the vehicle.

[0122] Step 104: According to the above historical environmental parameters and historical air-conditioning operation parameters, the initial weight value is adjusted to obtain a target weight value.

[0123] The following is a unified description of step 103 and step 104:

[0124] The above-mentioned historical environmental parameters refer to environmental parameters involved in the process of the vehicle traveling within a preset first historical mileage, which may include but are not limited to: ambient temperature, ambient humidity, weather conditions and other parameters.

[0125] The above-mentioned historical air-conditioning operating parameters refer to the operating parameters of the air conditioner installed in the vehicle while the vehicle is driving within a preset first historical mileage, which may include parameters such as the mileage of the vehicle when the air conditioner is heating and the mileage of the vehicle when the air conditioner is cooling.

[0126] In actual applications, in addition to the energy consumed by the vehicle engine to drive the vehicle during driving, the air conditioning of the vehicle will also consume a lot of energy. Furthermore, the more energy the air conditioning in the vehicle consumes, the greater the gap between the average energy consumption of the vehicle and the standard energy consumption. Therefore, after determining the initial weight value corresponding to the standard energy consumption of the vehicle, the executive body of the embodiment of the present application can further adjust the initial weight value according to the historical air conditioning operating parameters and historical environmental parameters of the vehicle when it is traveling within the historical mileage, so as to obtain the adjusted target weight value, so that the average energy consumption of the vehicle determined according to the target weight value is more in line with the actual operating conditions of the vehicle.

[0127] As for how to obtain the historical environmental parameters and historical air conditioning operating parameters of the vehicle, and how to adjust the initial weight value according to the historical environmental parameters and historical air conditioning operating parameters, it can be respectively described below. Figure 2 The process shown is explained and will not be described in detail here.

[0128] Step 105: Determine the average energy consumption of the vehicle at the current moment based on the above standard energy consumption, target weight value, and historical actual average energy consumption.

[0129] The above average energy consumption refers to the comprehensive average energy consumption of the vehicle at the current moment.

[0130] In one embodiment, the execution subject of the embodiment of the present application can be obtained by weighted summing the standard energy consumption and the actual average energy consumption of the vehicle. According to the above steps, the target weight value of the standard energy consumption can be determined, and the historical actual average energy consumption can be used as the actual average energy consumption of the vehicle. Based on this, the average energy consumption of the vehicle at the current moment can be determined according to the above standard energy consumption, the target weight value, and the historical actual average energy consumption.

[0131] As an optional implementation, the preset value can be subtracted from the target weight value to obtain the actual weight value, where the actual weight value is the weight value corresponding to the historical actual average energy consumption. The above preset value can be 1 or other values, and the embodiment of the present application does not limit this.

[0132] Afterwards, the above standard energy consumption and the historical actual average energy consumption can be weighted and summed according to the target weight value and the actual weight value to obtain the average energy consumption of the vehicle at the current moment.

[0133] As an exemplary implementation, the standard energy consumption and the target weight value may be multiplied to obtain a first value, and the historical actual average energy consumption and the actual weight value may be multiplied to obtain a second value. Finally, the first value and the second value may be added to obtain the average energy consumption of the vehicle at the current moment.

[0134] The technical solution provided by the embodiment of the present application determines the total mileage and standard energy consumption of the vehicle at the current moment, and obtains the historical actual average energy consumption, determines the initial weight value corresponding to the above-mentioned standard energy consumption according to the above-mentioned total mileage, determines the historical environmental parameters of the vehicle within a preset first historical mileage and the historical air-conditioning operating parameters of the vehicle, adjusts the initial weight value according to the above-mentioned historical environmental parameters and the historical air-conditioning operating parameters to obtain a target weight value, and determines the average energy consumption of the vehicle at the current moment according to the above-mentioned standard energy consumption, the target weight value, and the historical actual average energy consumption.

[0135] This technical solution dynamically adjusts the weight value of the vehicle's standard energy consumption by referring to the historical environmental parameters involved in the vehicle's historical driving process and the vehicle's historical air-conditioning operating parameters, thereby weighted summing the standard energy consumption and historical actual energy consumption to determine the vehicle's comprehensive average energy consumption. Since the weight value of the standard energy consumption is dynamically determined from multiple aspects such as the vehicle's total mileage, historical environmental parameters, and historical air-conditioning operating parameters, it is more in line with different driving conditions of the vehicle, making the determined comprehensive average energy consumption more accurate, thereby improving the accuracy of determining the vehicle's average energy consumption and enhancing user experience.

[0136] See also Figure 2 , which is a flow chart of an embodiment of another method for determining average vehicle energy consumption provided in an embodiment of the present application. Figure 2 The process shown in Figure 1 Based on the process shown in FIG. 1 , it describes how to obtain the historical environmental parameters and historical air conditioning operating parameters of the vehicle and determine the target weight value. Figure 2 As shown, the process may include the following steps:

[0137] Step 201 , determine whether the total mileage of the vehicle is greater than a preset mileage threshold, if so, execute step 202 ; if not, execute step 208 .

[0138] Step 202: Determine a plurality of historical temperature values ​​recorded within a first historical mileage closest to the current moment, as well as a cooling mileage and a heating mileage of the vehicle within the first historical mileage.

[0139] Step 203: determine the multiple historical temperature values ​​as historical environmental parameters of the vehicle within a first historical mileage, and determine the cooling mileage and the heating mileage as historical air-conditioning operation parameters of the vehicle within the first historical mileage.

[0140] The following is a unified description of steps 201 to 203:

[0141] The above-mentioned cooling mileage refers to the mileage corresponding to the cooling operation of the air conditioner in the vehicle during the driving of the vehicle within the first historical mileage.

[0142] The above-mentioned heating mileage refers to the mileage corresponding to the heating operation of the air conditioner in the vehicle during the vehicle's driving within the first historical mileage.

[0143] In actual applications, in addition to the energy consumed by the vehicle engine to drive the vehicle during driving, the air conditioning of the vehicle will also consume a lot of energy. Furthermore, the more energy the air conditioning in the vehicle consumes, the greater the gap between the average energy consumption of the vehicle and the standard energy consumption. Therefore, after determining the initial weight value corresponding to the standard energy consumption of the vehicle, the executive body of the embodiment of the present application can further adjust the initial weight value according to the historical air conditioning operating parameters and historical environmental parameters of the vehicle when it is traveling within the historical mileage, so as to obtain the adjusted target weight value, so that the average energy consumption of the vehicle determined according to the target weight value is more in line with the actual operating conditions of the vehicle.

[0144] Furthermore, as an optional implementation method, when the total mileage of a vehicle is small, the energy consumed by its air-conditioning operating parameters has little impact on the vehicle. Therefore, in order to simplify the operation, the executing entity of the embodiment of the present application may first determine whether the total mileage of the vehicle is greater than a preset mileage threshold (for example, 1000 km) when obtaining historical environmental parameters and historical air-conditioning operating parameters.

[0145] Optionally, when it is determined that the total mileage of the vehicle is greater than the mileage threshold, it means that the vehicle has traveled a long distance and the air conditioning operation has a greater impact on the average energy consumption of the vehicle. Therefore, in order to eliminate the impact of the air conditioning operation on the average energy consumption of the vehicle, the execution entity of the embodiment of the present application can obtain multiple historical temperature values ​​recorded within the first historical mileage closest to the current moment, as well as the cooling mileage and heating mileage of the vehicle within the first historical mileage.

[0146] Furthermore, during operation, the vehicle may record the current temperature value once per unit mileage, for example, recording the temperature value once per 1 km, and then multiple historical temperature values ​​may be recorded within the first historical mileage.

[0147] Among them, the above-mentioned first historical mileage is the preset mileage of the vehicle's most recent mileage, such as the most recent 1000km. Since the first historical mileage is the vehicle's most recent mileage, it has a greater impact on the vehicle's average energy consumption at the current moment and is representative. Therefore, the initial weight value is adjusted through the vehicle's air conditioning operating parameters within the first historical mileage, so that the target weight value can be determined more accurately.

[0148] Afterwards, a plurality of historical temperature values ​​may be determined as historical environmental parameters of the vehicle within a first historical mileage, and the cooling mileage and the heating mileage may be determined as historical air-conditioning operation parameters of the vehicle within the first historical mileage.

[0149] Optionally, when it is determined that the total mileage of the vehicle is less than or equal to the mileage threshold, it means that the vehicle has traveled a shorter distance and the air conditioning operation has less impact on the average energy consumption of the vehicle. In order to improve efficiency, the execution entity of the embodiment of the present application may execute step 208, that is, determine the initial weight value as the target weight value, and do not adjust the initial weight value.

[0150] Step 204: Determine an average temperature value of multiple historical temperature values.

[0151] Step 205: Compare the average temperature value with a preset temperature value threshold.

[0152] Step 206: When it is found that the temperature value is greater than or equal to the temperature value threshold, the initial weight value is adjusted according to the refrigeration mileage to obtain a target weight value.

[0153] Step 207: When it is found that the average temperature value is less than the temperature value threshold, the initial weight value is adjusted according to the heating mileage to obtain a target weight value.

[0154] The following is a unified description of steps 204 to 207:

[0155] In an embodiment of the present application, in order to eliminate the impact of air conditioning operation on the average energy consumption of the vehicle during driving, the executing entity of the embodiment of the present application can adjust the initial weight value of the standard energy consumption according to historical environmental parameters and historical air conditioning operation parameters to obtain the target weight value.

[0156] Furthermore, since the air conditioner includes cooling operation and heating operation, in order to determine whether the cooling operation or the heating operation of the vehicle air conditioner has a greater impact within the first historical mileage, the execution subject of the embodiment of the present application can be determined based on the historical temperature value in the historical environmental parameters.

[0157] As an exemplary embodiment, an average temperature value of multiple historical temperature values ​​may be determined and compared with a preset temperature value threshold value. The temperature value threshold value may be the temperature of the vehicle's initial air conditioning setting, such as 24°C, which is a relatively comfortable temperature for human body.

[0158] Optionally, when the average temperature value is compared to be greater than or equal to the above-mentioned temperature value threshold, it means that the ambient temperature was high when the vehicle was traveling within the first historical mileage, and a longer mileage of refrigeration operation was required, that is, the refrigeration operation has a greater average energy consumption for the vehicle. Therefore, the initial weight value can be adjusted according to the refrigeration mileage to obtain the target weight value.

[0159] As an exemplary implementation, when the initial weight value is adjusted according to the refrigeration mileage, the refrigeration mileage and the initial weight value may be input into the following first adjustment formula (II) to obtain the target weight value:

[0160] K=(1-0.3×log M x1)×K0 Formula (II)

[0161] Among them, the above K is the target weight value, the above M is the first historical mileage, the above x1 is the refrigeration mileage, and the above K0 is the initial weight value.

[0162] Optionally, when the average temperature value is compared to be less than the above-mentioned temperature value threshold, it means that the ambient temperature is low when the vehicle is traveling within the first historical mileage, and a longer mileage of heating operation is required, that is, the heating operation consumes a large amount of average energy for the vehicle. Therefore, the initial weight value can be adjusted according to the heating mileage to obtain the target weight value.

[0163] As an exemplary implementation, when the initial weight value is adjusted according to the heating mileage, the heating mileage and the initial weight value may be input into the following second adjustment formula (III) to obtain the target weight value:

[0164] K=(1-0.3×log M x2)×K0 Formula (III)

[0165] Among them, the above K is the target weight value, the above M is the first historical mileage, the above x2 is the heating mileage, and the above K0 is the above initial weight value.

[0166] Step 208: Determine the initial weight value as the target weight value.

[0167] The technical solution provided by the embodiment of the present application determines whether the total mileage of the vehicle is greater than a preset mileage threshold. If so, multiple historical temperature values ​​recorded in the first historical mileage closest to the current moment, as well as the cooling mileage and heating mileage of the vehicle within the first historical mileage, are determined, the multiple historical temperature values ​​are determined as historical environmental parameters of the vehicle within the first historical mileage, and the cooling mileage and heating mileage are determined as historical air-conditioning operating parameters of the vehicle within the first historical mileage, an average temperature value of the multiple historical temperature values ​​is determined, the average temperature value is compared with a preset temperature value threshold, and when the temperature value is compared to be greater than or equal to the temperature value threshold, the initial weight value is adjusted according to the cooling mileage to obtain a target weight value, and when the average temperature value is compared to be less than the temperature value threshold, the initial weight value is adjusted according to the heating mileage to obtain a target weight value; if not, the initial weight value is determined as the target weight value.

[0168] This technical solution determines the historical environmental parameters and historical air-conditioning operating parameters involved in the vehicle's driving within the historical mileage, and adjusts the initial weight value of the standard energy consumption according to the historical environmental parameters and historical air-conditioning operating parameters. It takes into account the impact of air-conditioning operation on the average energy consumption during vehicle driving, so that the adjusted target weight value is more accurate, so that the average energy consumption of the vehicle determined based on the target weight value is more in line with the actual operating conditions of the vehicle, and a more accurate determination of the target weight value of the vehicle's standard energy consumption is achieved, thereby achieving a more accurate determination of the vehicle's average energy consumption.

[0169] To facilitate understanding of the vehicle average energy consumption determination method provided in this application, an example is given below:

[0170] 1. The whole vehicle is subjected to CLTC working condition energy consumption test. The CLTC test generally adopts normal temperature conditions of 20-30℃, and the average energy consumption Qc of the conditions is recorded.

[0171] 2. The vehicle controller uses the average working condition energy consumption as the basis for subsequent comprehensive energy consumption calculations; the total mileage S of the vehicle after leaving the factory is recorded. As the total mileage increases, the initial weight value K0 of the average working condition energy consumption in subsequent calculations is gradually reduced until the total mileage reaches a certain value (the threshold is set to 10,000 km), and the maximum value of S is limited to 10,000; the initial weight value K0 can be obtained by the following formula (IV):

[0172] K0=k1*(10000-S) / 10000+k2*((10000-S) / 10000) 2 Formula (IV)

[0173] Among them, the values ​​of k1 and k2 are 0.5 and 0.4 respectively, and the values ​​of k1 and k2 are obtained through driving tests under normal temperature urban conditions.

[0174] 3. The vehicle controller records the ambient temperature of the last 1000 km, recording once every 1 km, and the ambient temperature values ​​are T1, T2, ..., T 1000 , use the above data to calculate the average ambient temperature Ta through the following formula (V):

[0175] Ta=∑(T1,T2,…,T 1000 ) / 1000 Formula (V)

[0176] 4. The vehicle controller records the cumulative mileage of the passenger compartment air conditioning switch in the last 1000km, of which the cumulative mileage for heating is x1 and the cumulative mileage for cooling is x2.

[0177] 5. Calculate the target weight value K for comprehensive energy consumption calculation under working condition. When the total mileage is less than 1000 km, K is the initial weight value K0. When the total mileage exceeds 1000 km, if the average ambient temperature Ta ≥ 24 °C, the target weight value K is calculated by the following formula (VI):

[0178] K=(1-0.3×log 1000 x1)×K0 Formula (VI)

[0179] Among them, the above K is the target weight value, the above x1 is the heating mileage, and the above K0 is the above initial weight value.

[0180] Optionally, if the average ambient temperature Ta is less than 24° C., the target weight value K is calculated by the following formula (VII):

[0181] K=(1-0.3×log 1000 x2)×K0 Formula (VII)

[0182] Among them, the above K is the target weight value, the above x2 is the heating mileage, and the above K0 is the above initial weight value.

[0183] Among them, the setting of the above-mentioned ambient temperature threshold of 24°C is obtained by referring to the default air-conditioning setting. The initial air-conditioning setting temperature of the vehicle is 24°C, which is a more comfortable temperature for the human body. Generally, when the ambient temperature exceeds this threshold, air-conditioning cooling is required, and when it is lower than this threshold, air-conditioning heating is required. The coefficient K is obtained by referring to the air-conditioning cooling mileage and heating mileage according to the trend of the ambient temperature.

[0184] 6. The vehicle controller records the actual average energy consumption of the last 50 km as Qact; when calculating the comprehensive average energy consumption, the CLTC standard energy consumption and the actual real-time average energy consumption are used, and the comprehensive average energy consumption Q can be obtained by the following formula (VIII):

[0185] Q=K*Qc+(1-K)*Qact Formula (8)

[0186] Among them, Q is the average energy consumption, K is the target weight value, Qc is the standard energy consumption, and Qact is the actual average energy consumption.
