Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present disclosure, "a plurality" means two or more unless otherwise specified.

Additionally, the use of "based on" or "according to" means open and inclusive, as a process, step, calculation, or other action that is "based on" or "according to" one or more stated conditions or values may in practice be based on additional conditions or exceeding the stated values.

Currently, the historical oil consumption of a vehicle or model of a vehicle can be used for analysis: the change conditions of the historical oil consumption in different periods, the influence degree of different influence factors on the historical oil consumption in different periods, the effect evaluation of the oil-saving product, the prediction on the future oil consumption condition and the like. The universality and the effect of the oil-saving product can be evaluated by comparing the oil consumption condition when the oil-saving product is not used with the oil consumption condition when the oil-saving product is used.

Before the historical oil consumption of the vehicle or the vehicle type is used in the various analysis scenes, the historical average oil consumption of the vehicle or the vehicle type needs to be calculated. In the related art, the electronic device in the background may obtain n statistical samples of the same model or the same vehicle under the same or similar road conditions and average speed conditions from the database, and obtain the average oil consumption according to the n statistical samples. However, for some automobiles, such as new automobiles, automobiles that do not access the internet of vehicles, or automobiles that cannot report service data due to a failure of the vehicle-mounted terminal, the electronic device cannot acquire the service data of the automobiles, so that the historical fuel consumption of the automobiles cannot be determined.

In order to solve the problem that the electronic equipment cannot determine the historical oil consumption of vehicles such as a new vehicle and an automobile which is not accessed to the internet of vehicles, the embodiment of the invention provides a method for determining the oil consumption of the vehicle. Wherein the reference data satisfies the calculation condition of the fuel consumption of the vehicle. When the target vehicle is one vehicle, the reference vehicle includes a vehicle of the same vehicle model as the target vehicle and the vehicle model or the reference vehicle is the target vehicle. When the target vehicle includes a vehicle of a target model, the reference vehicle is the target vehicle.

In this way, when the target historical data of the target vehicle in the first time period does not meet the calculation condition of the fuel consumption of the vehicle, the electronic equipment calculates the average fuel consumption of the target vehicle in the first time period based on the reference data by acquiring the reference data of the target vehicle in the second time period of the same vehicle type meeting the calculation condition of the fuel consumption of the vehicle or acquiring the reference data of the target vehicle in the second time period meeting the calculation condition of the fuel consumption of the vehicle, so that the historical fuel consumption of vehicles such as new vehicles and vehicles which are not accessed into the internet of vehicles is estimated. Because the reference data is accurate historical data which meets the calculation conditions and is obtained from the vehicle database, the estimated oil consumption data is also accurate, and reliable data support is provided for subsequent analysis.

In addition, since the vehicle database stores the historical data of the full life cycle of the vehicle, the electronic equipment can determine the average oil consumption of the full life cycle of the vehicle and the average oil consumption of the full life cycle of the vehicle type through the data in the vehicle database.

Furthermore, the embodiment of the invention realizes the quantification of the influence degree of different influence factors on the historical oil consumption, and facilitates the analysis of subsequent effects.

Fig. 1 shows one structure of the internet of vehicles system. As shown in fig. 1, the internet of vehicles system may include: a car 11 and a back office device 12. Among other things, backend device 12 may include a vehicle database, an electronic device, and the like. The automobile 11 and the background equipment 12 establish connection in a wireless communication mode.

The automobile 11 is provided with a vehicle-mounted terminal, and the vehicle-mounted terminal is used for reporting the service data of the automobile 11 to the electronic equipment. The traffic data may include the vehicle model of the automobile 11, a travel track, position information, a load, a map, and the like.

And the electronic equipment is used for receiving the service data reported by the automobile 11, processing the service data by adopting a big data technology, for example, determining the label of each dimension in a plurality of dimensions corresponding to the travel of the automobile 11 through a big data algorithm according to the service data, and storing the processed data in a vehicle database. And the electronic equipment is also used for acquiring target historical data of the target vehicle in a first time period in the vehicle database according to the service requirement, and acquiring reference data of the reference vehicle in a second time period in the vehicle database, wherein the reference data meet the calculation condition of the vehicle oil consumption when the calculation condition of the vehicle oil consumption is determined not to be met according to the target historical data. Then, the average fuel consumption of the target vehicle in the first time period is determined according to the reference data.

In some embodiments, the electronic device may be a terminal device. The terminal device may be a mobile phone, a tablet computer, a desktop, a laptop, a handheld computer, a notebook computer, etc.

The execution subject of the method for determining the vehicle fuel consumption provided by the embodiment of the invention is a device for determining the vehicle fuel consumption. The device for determining the fuel consumption of the vehicle may be the electronic device, a CPU in the electronic device, a calculation module for determining the fuel consumption of the vehicle in the electronic device, or a client for determining the fuel consumption of the vehicle in the electronic device. The embodiment of the invention takes a method for determining the fuel consumption of a vehicle executed by electronic equipment as an example, and the method for determining the fuel consumption of the vehicle provided by the invention is explained.

Based on the structure of the internet of vehicles system and the introduction of the structure of the device for determining the fuel consumption of the vehicle, the embodiment of the invention provides a method for determining the fuel consumption of the vehicle. As shown in fig. 3, the method for determining the fuel consumption of a vehicle may include the following steps 301 to 304.

301. The electronic device obtains target history data of the target vehicle in a first time period in a vehicle database.

The target vehicle may be a vehicle, or the target vehicle may include a vehicle of a target model.

When the vehicle oil consumption needs to be calculated, the electronic equipment can respond to the operation of inputting the service requirement on the electronic equipment by a user, and the target historical data of the target vehicle in the first time period can be obtained in the vehicle database according to the service requirement. The vehicle database is used for storing historical data of a full life cycle of the vehicle, wherein the historical data of the full life cycle refers to relevant data of the vehicle from sale to current.

For example, the related data may include a mileage, a time of failure, a fuel consumption, a label for each of the plurality of dimensions, and the like corresponding to each trip, where the label is used to indicate attribute information of the corresponding trip. The tag of each of the multiple dimensions may be determined according to the service data and stored in the vehicle database after the electronic device receives the service data of the target trip reported by the target vehicle before calculating the fuel consumption of the target vehicle.

For example, the plurality of dimensions may include: weather dimension, load dimension, vehicle model dimension, vehicle condition dimension, road condition dimension, speed dimension, and the like. The weather dimension may include temperature, humidity, air pressure, and the like, and may be determined according to the position information and the travel time included in the service data reported by the target vehicle. The vehicle condition dimension may include the age of the vehicle, historical service conditions, historical maintenance conditions, historical operating conditions, and the like. The road condition dimension refers to a distance condition of a corresponding distance, and can be determined according to a driving track and a map in service data reported by a target vehicle. The speed dimension may include an instantaneous speed, an average speed, etc. for the corresponding trip, where the average speed may be determined based on the mileage and the time of the trip. Of course, the related data may also include other data of the trip, and the multiple dimensions may also include other dimensions besides the dimensions listed above, and the embodiment of the present invention is not limited herein.

It can be understood that the service requirements are different, and the target historical data acquired by the electronic device is also different. In one case, the business requirement may include the target vehicle, at which point the electronic device may obtain historical data for the target vehicle's full life cycle. In one case, the business requirement may include the target vehicle and a time period, and the electronic device may obtain historical data of the target vehicle in a first time period, where the first time period is determined according to a preset rule in the business requirement. For example, if a time period in the service requirement is 6 months in 2020, the first time period obtained by using the preset rule may be 6 months in 2020, may also be the second quarter in 2020, may also be the whole year in 2020, and may also be historical data of the whole life cycle. Different preset rules can be set in the electronic equipment in advance according to actual conditions. In one case, the business requirements may include the target vehicle, a time period, some conditions, which may include load conditions, weather conditions, etc., at which time the electronic device may obtain historical data of the target vehicle under the some conditions for a first time period.

Illustratively, it is assumed that the business requirements input by the user on the electronic device include: vehicle a, 6 months 2020, heavy load condition, clear condition, the electronic device may then obtain from the vehicle database historical data for all trips that vehicle a was in heavy load condition and clear condition in 6 months 2020.

302. And when the calculation condition of the fuel consumption of the vehicle is determined not to be met according to the target historical data, the electronic equipment acquires reference data of the reference vehicle in a second time period from the vehicle database.

Because certain requirements are required on the historical data of the vehicle when the fuel consumption of the vehicle is calculated, the fuel consumption calculated only by the historical data meeting the requirements is reliable, and therefore after the target historical data of the target vehicle in a first time period is obtained, the electronic equipment can determine whether the calculation conditions of the fuel consumption of the vehicle are met according to the target historical data.

Specifically, the target historical data may include historical driving mileage of the target vehicle over the first time period and a time to failure. The electronic device may determine whether the target historical data satisfies the calculation condition for the fuel consumption of the vehicle by determining whether the historical driving mileage is greater than or equal to a preset mileage. Alternatively, the electronic device may determine whether the target history data satisfies the calculation condition of the fuel consumption of the vehicle by determining whether the failure time is less than or equal to a preset time. Alternatively, the electronic device may determine whether the target history data satisfies the calculation condition of the fuel consumption of the vehicle by combining the two determination conditions. Of course, the electronic device may also use other determination conditions to determine whether the calculation condition of the vehicle fuel consumption is satisfied, and the embodiment of the present invention is not limited herein.

And when the historical driving mileage is less than the preset mileage, or the fault time is greater than the preset time, or the historical driving mileage is less than the preset mileage, and the fault time is greater than the preset time, the electronic equipment determines that the calculation condition of the fuel consumption of the vehicle is not met according to the target historical data, and the electronic equipment can acquire reference data of the reference vehicle in a second time period from a vehicle database, wherein the reference data meet the calculation condition of the fuel consumption of the vehicle.

It is to be understood that when the target vehicle is a vehicle, the reference vehicle may include a vehicle of the same vehicle model as that of the target vehicle or the reference vehicle may be the target vehicle. When the target vehicle includes a target model of vehicle, the reference vehicle may be the target vehicle.

In addition, the target vehicle is a vehicle, and when the reference vehicle includes a vehicle of the same vehicle type, the second time period may be the same as or different from the first time period. The reference vehicle is the same as the target vehicle, and the second time period is different from the first time period.

When the historical mileage is greater than or equal to the preset mileage, or the failure time is less than or equal to the preset time, or the historical mileage is greater than or equal to the preset mileage and the failure time is less than or equal to the preset time, the electronic device determines that the calculation condition of the fuel consumption of the vehicle is satisfied according to the target historical data, and then the following step 304 may be executed.

303. The electronic device determines a first average fuel consumption based on the reference data.

After the electronic device acquires the reference data, the average fuel consumption of the target vehicle in the first time period may be determined in the following ways, that is, the first average fuel consumption is determined.

In the method 1, when the target vehicle is a vehicle, the reference vehicle includes a vehicle of which the vehicle model is the same as that of the target vehicle, or when the target vehicle includes a vehicle of which the vehicle model is the same as that of the target vehicle, and the reference vehicle is the target vehicle, the electronic device may determine, according to the reference data, the average oil consumption of the reference vehicle in the second time period, that is, determine the second average oil consumption, and determine, according to the average oil consumption of the target vehicle in the preset time period and the average oil consumption of the reference vehicle in the preset time period, a correction coefficient, which satisfies the following formula: and the correction coefficient is equal to the average fuel consumption of the target vehicle in the preset time period/the average fuel consumption of the reference vehicle in the preset time period. And then, the electronic equipment determines a first average oil consumption according to the correction coefficient and the second average oil consumption, wherein the first average oil consumption meets the following formula: and the first average fuel consumption is equal to the second average fuel consumption.

It should be noted that, in the embodiment of the present invention, the average fuel consumption calculated by the electronic device may be an average fuel consumption of hundred kilometers. In one implementation, the average hundred kilometers fuel consumption is 100 (total fuel consumption/total mileage driven). In another implementation, the average fuel consumption per hundred kilometers is equal to the average of the average fuel consumption per hundred kilometers for each trip. The embodiment of the present invention is not limited to specific method for calculating the average fuel consumption, and the embodiment of the present invention takes the calculation of the average fuel consumption by the first method as an example.

In addition, the preset time period may be set by the user in advance according to the application scenario, or may be a default value. The duration of the preset time period is usually longer, so that the reliability of the calculated average fuel consumption can be ensured, and the reliability of the correction coefficient can be ensured.

For example, assuming that the target vehicle is the vehicle a, the reference vehicles include the vehicle B, the vehicle C, and the vehicle D, and the vehicle models of these three vehicles are the same as the vehicle model of the vehicle a. And assuming that the first time period is 6 months in 2020, the second time period is 6 months in 2020, and the preset time period is one whole year in 2020. When the average fuel consumption per hundred kilometers of the vehicle A in 6 months in 2020 needs to be calculated, and the historical data of the vehicle A in 6 months in 2020 does not meet the calculation condition, the electronic device may calculate the average fuel consumption per hundred kilometers n of the vehicle A, the vehicle B, the vehicle C and the vehicle D in 6 months in 2020, calculate the average fuel consumption per hundred kilometers in the year A, specifically calculate the fuel consumption per hundred kilometers in month first, then calculate the average value of the fuel consumption per hundred kilometers in month to obtain the fuel consumption per hundred kilometers in year B1, or may calculate the total fuel consumption in 2020 divided by the total driving mileage in 2020 multiplied by 100 to obtain B1, and calculate the average fuel consumption per hundred kilometers in year B2 of the vehicle A, the vehicle B, the vehicle C and the vehicle D to obtain a correction coefficient B1/B2. Finally, the first average fuel consumption is n (b1/b 2).

For another example, as shown in fig. 4, the target vehicle includes vehicles of target models, such as four vehicles of the same type as vehicle a, vehicle B, vehicle C, and vehicle D, and the reference vehicle is the target vehicle. The first time period is 2020 and 11 months, the second time period is 2019 and 11 months, and the preset time period is a whole year. In fig. 4, the historical data of months 4 and 11 in 2020 do not satisfy the calculation condition for the fuel consumption of the vehicle, and the historical data of months 12 in 2019 both satisfy the calculation condition for the fuel consumption of the vehicle.

When the average fuel consumption per hundred kilometers of the vehicles A, B, C and D in 11 months in 2020 needs to be calculated, and the historical data of the four vehicles in 11 months in 2020 does not meet the calculation condition, the electronic equipment can calculate the average fuel consumption per hundred kilometers m of the vehicles A, B, C and D in 11 months in 2019, calculate the average fuel consumption per hundred kilometers of the vehicles A, B, C and D in 2019 and 2020C 1 and C2 respectively, and obtain the correction coefficient C2/C1. Finally, the first average fuel consumption is m (c2/c 1).

It can be understood that since the historical data of months 4 and 11 in 2020 does not satisfy the calculation condition, the electronic device only needs to calculate the average fuel consumption of hundred kilometers in months other than months 4 and 11 when calculating the fuel consumption of hundred kilometers in each year in 2020.

In the method 2, when the target vehicle is a vehicle and the reference vehicle includes a vehicle of which the vehicle model is the same as the vehicle model of the target vehicle, the electronic device may obtain the first vehicle oil consumption change map and the vehicle model oil consumption change map, and obtain the base period time period when the first vehicle oil consumption change map and the vehicle model oil consumption change map are similar to each other. The first vehicle oil consumption change diagram is a change diagram of the average oil consumption of the target vehicle along with unit time in a second time period, the vehicle type oil consumption change diagram is a change diagram of the average oil consumption of the reference vehicle along with unit time in the second time period, and the second time period comprises the first time period and the base period time period. Then, the electronic equipment determines a change coefficient according to vehicle type oil consumption corresponding to the first time period and the base time period respectively, and determines a first average oil consumption according to the vehicle oil consumption corresponding to the base time period and the change coefficient. In this way, the estimation of the first average fuel consumption of the target vehicle by using vehicles of the same type is realized.

It can be understood that the electronic device may determine whether the first vehicle oil consumption change map is similar to the vehicle oil consumption change map by determining the similarity of the graphs and calculating the variance to determine the fluctuation condition of the change map, and other manners of determining whether the first vehicle oil consumption change map is similar to the vehicle oil consumption change map may also be used.

Optionally, based on the vehicle type oil consumption change map, the electronic device may obtain vehicle type oil consumptions corresponding to other time periods in the second time period except for the base time period and the first time period, and determine a change coefficient according to the vehicle type oil consumptions corresponding to the other time periods and the vehicle type oil consumption corresponding to the base time period. In the first vehicle oil consumption change diagram, the electronic device estimates the vehicle oil consumption corresponding to the other time periods according to the vehicle oil consumption corresponding to the base period time period and the determined change coefficient, compares the estimated vehicle oil consumption with the vehicle oil consumption corresponding to the other time periods in the first vehicle oil consumption change diagram, and if the absolute value of the difference is smaller, the electronic device can determine the first average oil consumption by adopting a mode 2. Otherwise, the electronic device determines the first average oil consumption in other ways.

For example, the target vehicle is a vehicle a, and the reference vehicle includes: vehicle B, vehicle C, vehicle D. The first time period is 12 months in 2020, the base period is 1 month, and the second time period is one whole year in 2020. As shown in fig. 5, the average fuel consumption of a vehicle a in 2020 is plotted against the months, and the average fuel consumption of a vehicle of one type, i.e., a vehicle a, a vehicle B, a vehicle C, and a vehicle D in 2020 is plotted against the months. As can be seen from fig. 5, the relationship between the two is similar. When the average hundred kilometer oil consumption of the vehicle A in 12 months in 2020 needs to be calculated, but the historical data of the vehicle A in 12 months in 2020 does not meet the calculation conditions, the electronic equipment determines 1 month as a base period time period, and calculates the change coefficients of the vehicle type oil consumption of 2 months to 12 months per month relative to the vehicle type oil consumption of 1 month based on the vehicle type oil consumption relational graph. Then, based on the first vehicle oil consumption relation graph, the electronic equipment multiplies the vehicle oil consumption corresponding to 1 month by the change coefficients corresponding to 2 months to 11 months respectively to obtain estimated values of the vehicle oil consumption of 2 months to 11 months, and the estimated values are compared with the real values respectively. If the difference values between the estimated value and the true value are small, the electronic equipment multiplies the vehicle oil consumption corresponding to 1 month by the change coefficient corresponding to 12 months to obtain a first average oil consumption of 12 months.

Mode 3, in a case where the reference vehicle is a target vehicle, the target vehicle is a vehicle of one vehicle or one vehicle type. The electronic equipment can obtain a base period time period, a first vehicle fuel consumption change diagram and a second vehicle fuel consumption change diagram, wherein the second vehicle fuel consumption change diagram is a change diagram of the average fuel consumption of the target vehicle along with unit time in a third time period, and the third time period comprises the first time period. Then, the electronic equipment determines a change coefficient according to the average oil consumption respectively corresponding to the base period time period and the first time period in the first vehicle oil consumption change diagram, and determines the first average oil consumption according to the average oil consumption corresponding to the base period time period in the second vehicle oil consumption change diagram and the change coefficient.

Optionally, based on the second vehicle oil consumption change map, the electronic device may obtain the vehicle oil consumption corresponding to the other time periods in the third time period except for the base time period and the first time period, and determine a change coefficient according to the vehicle oil consumption corresponding to the other time periods and the vehicle oil consumption corresponding to the base time period. In the first vehicle oil consumption change diagram, the electronic device estimates the vehicle oil consumption corresponding to the other time periods according to the vehicle oil consumption corresponding to the base period time period and the determined change coefficient, compares the estimated vehicle oil consumption with the vehicle oil consumption corresponding to the other time periods in the first vehicle oil consumption change diagram, and if the absolute value of the difference is smaller, the electronic device can determine the first average oil consumption in a mode 3. Otherwise, the electronic device determines the first average oil consumption in other ways.

For example, assume that the target vehicle and the reference vehicle are vehicle a, the first time period is 12 months in 2020, the base time period is 1 month, the second time period is one full year in 2020, and the third time period is 2019. The historical data of the vehicle a in 2020 and 12 do not satisfy the calculation condition, and the electronic device may determine, based on the second vehicle fuel consumption change map, a change coefficient of the vehicle fuel consumption corresponding to 12 months in 2019 relative to the vehicle fuel consumption corresponding to 1 month in 2019, and calculate a change coefficient of the vehicle fuel consumption corresponding to 2 months to 11 months and each month relative to the vehicle fuel consumption of 1 month. Then, based on the first vehicle oil consumption change diagram, the electronic equipment multiplies the vehicle oil consumption corresponding to 1 month in 2020 by the change coefficients corresponding to 2 months to 11 months respectively to obtain estimated values of the vehicle oil consumption of 2 months to 11 months, and the estimated values are compared with the real values respectively. If the difference between the estimated value and the true value is small, the electronic equipment multiplies the vehicle oil consumption corresponding to 1 month in 2020 by the change coefficient to obtain a first average oil consumption of 12 months in 2020.

Similarly, when the target vehicle and the reference vehicle are the vehicle a, the vehicle B, the vehicle C, and the vehicle D, the first time period is 12 months in 2020, the base time period is 1 month, the second time period is one whole year in 2020, and the third time period is 2019. The historical data of the vehicle a, the vehicle B, the vehicle C and the vehicle D in 2020 and 12 do not satisfy the calculation condition, and the electronic device may determine, based on the second vehicle fuel consumption change map, a change coefficient of the vehicle fuel consumption corresponding to the month 12 in 2019 relative to the vehicle fuel consumption corresponding to the month 1 in 2019. Then, based on the first vehicle fuel consumption change map, the electronic device multiplies the vehicle fuel consumption corresponding to 1 month in 2020 by the change coefficient to obtain a first average fuel consumption of 12 months in 2020. Thus, the fuel consumption of the vehicle in 2019 is estimated by the electronic equipment to obtain the fuel consumption of the vehicle in 2020.

It should be noted that, in the embodiment of the present invention, the electronic device may determine the first average oil consumption in the above manner according to an actual situation, and the embodiment of the present invention is not limited herein.

304. When the calculation condition of the oil consumption of the vehicle is determined to be met according to the target historical data, the electronic equipment determines a first average oil consumption according to the target historical data.

When determining, according to the target historical data, that the calculation condition of the vehicle oil consumption is satisfied, the electronic device may determine, according to the target historical data, a first average oil consumption, that is, determine an average oil consumption of the target vehicle in a first time period.

In a specific implementation, the electronic device may obtain a label, a mileage number, and an oil consumption number of each of multiple dimensions corresponding to each trip in at least one trip included in the target historical data, and classify the at least one trip according to the label of each dimension to obtain multiple trip sets, where the label of each dimension in the multiple dimensions corresponding to the trip included in each trip set is the same. And then, the electronic equipment calculates a first average oil consumption corresponding to each travel set according to the mileage and the oil consumption corresponding to each travel included in each travel set.

After determining the first average oil consumption, the electronic device may compare the first average oil consumption with a preset threshold to determine whether the calculation result is accurate. And if so, taking the calculated first average oil consumption as a final result. If not, the electronic device may determine the first average fuel consumption in the manner of step 303.

In this way, when the target historical data of the target vehicle in the first time period does not meet the calculation condition of the fuel consumption of the vehicle, the electronic equipment calculates the average fuel consumption of the target vehicle in the first time period based on the reference data by acquiring the reference data of the target vehicle in the second time period of the same vehicle type meeting the calculation condition of the fuel consumption of the vehicle or acquiring the reference data of the target vehicle in the second time period meeting the calculation condition of the fuel consumption of the vehicle, so that the historical fuel consumption of vehicles such as new vehicles and vehicles which are not accessed into the internet of vehicles is estimated. Because the reference data is accurate historical data which meets the calculation conditions and is obtained from the vehicle database, the estimated oil consumption data is also accurate, and reliable data support is provided for subsequent analysis.

In addition, since the vehicle database stores the historical data of the full life cycle of the vehicle, the electronic equipment can determine the average oil consumption of the full life cycle of the vehicle and the average oil consumption of the full life cycle of the vehicle type through the data in the vehicle database.

Optionally, in the embodiment of the present invention, the electronic device may further determine the influence degree of each influence factor on the average fuel consumption. The influencing factors may include: weather, road conditions, vehicle conditions, load, speed, etc.

Specifically, the electronic device may determine the degree of influence of the different influencing factors on the average fuel consumption based on the historical data of the full life cycle of the vehicle in the vehicle database. When the influence of a certain influence factor is determined, the influence factor can be ensured to be different, other influence factors are the same, the average oil consumption corresponding to different values under the influence factor is calculated, and the average oil consumption corresponding to adjacent samples is compared.

For example, suppose that the influence of the load on the fuel consumption needs to be calculated, the average fuel consumption per hundred kilometers under no load is a1, the average fuel consumption per hundred kilometers under light load is a2, and the average fuel consumption per hundred kilometers under heavy load is a 3. Then, the electronic device calculates n1 ═ a2/a1, n2 ═ a3/a2, and finally obtains (n1+ n2)/2, which is the influence factor of the load on fuel consumption. If a certain intermediate value is missing, namely cross-group calculation is performed, the electronic equipment performs evolution calculation on the ratio of the cross-group calculation, 2 power is evolved for 1 group, 3 power is evolved for 2 groups, and the like.

For another example, suppose that a batch of 1-year (model K) vehicles run for 10 months and have an average fuel consumption of 27L/100km under no load, a batch of 3-year vehicles of the same model, a batch of 10-month vehicles run for 28L/100km under no load, and a batch of 6-year vehicles of the same model, have an average fuel consumption of 29.0L/100km under 10-month running and no load. Then, the electronic device determines that the influence factor of the vehicle age on the fuel consumption is: (28/27+29/28)/2 is 1.04.

For another example, assuming that a batch of vehicles of 3 years (with the vehicle type K) is driven for 5 months and the average fuel consumption under light load is 30L/100km, a batch of vehicles of the same vehicle type for 3 years is driven for 5 months and the average fuel consumption under heavy load is 35.8L/100km, and a batch of vehicles of the same vehicle type for 3 years is driven for 5 months and the average fuel consumption under no load is 27.5L/100km, the electronic device determines that the influence factor of the load on the fuel consumption is: the factor of the fuel consumption due to the load is (1.19+1.09)/2 is 1.14, in conclusion, with M1 being 35.8/30 being 1.19, M2 being 30/27.5 being 1.09.

It should be noted that the above needs to relatively reasonably grade each factor according to data performance, such as: the load is divided into no load, light load and heavy load. The age of the car is divided into: 0-2 years, 2-4 years, 4-6 years, more than 6 years. The ranking results may be stored in the electronic device empirically in advance.

Therefore, the influence degree of different influence factors on the historical oil consumption is quantized, and the analysis of subsequent effects is facilitated.
