Of course, the method may also be applied to other implementation environments and executed by a server device in other implementation environments, which is not limited in this embodiment. As shown in fig. 2, the method at least includes steps S210 to S230, which are described in detail as follows:
s210: the method comprises the steps of obtaining the moving distance and the moving duration of the motor vehicle in the moving process, and collecting the corresponding operation data of the engine in the moving duration.
Motor vehicles include fuel-powered vehicles, hybrid gasoline-electric vehicles, and the like.
The operation data comprises data such as engine speed, basic model charging efficiency, engine load, fuel injection quantity and the like in the operation process of the motor vehicle.
S220: if the moving distance is detected to be larger than the preset distance threshold value and the moving time length is detected to be larger than the preset time length threshold value, calculating based on the operation data to obtain a target inflation efficiency correction value corresponding to each moment in the moving time length; the operation data comprise basic model inflation efficiency corresponding to each moment in the moving duration.
The preset distance threshold and the preset duration threshold are preset thresholds set according to motor vehicles of different models and different performances, that is, the preset thresholds set for different motor vehicles may have different sizes.
The basic model inflation efficiency is obtained by calculation according to the oil consumption data in the calibration process of the rack, the basic model inflation efficiency corresponding to each moment in the embodiment is an actual value, and because the actual value has a certain error, the target restart efficiency correction value is needed to correct the actual value, so that the corrected inflation efficiency is obtained.
For an exemplary description of S220, if the moving distance is 80 kilometers, the moving duration is 30 minutes, the preset distance threshold is 70 kilometers, the preset duration threshold is 25 minutes, and the moving distance and the moving duration are respectively greater than the corresponding preset thresholds, the basic model inflation efficiency corresponding to each time is obtained by using the operation data acquired within the moving duration.
S230: and correcting the basic model inflation efficiency at the corresponding moment based on the target inflation efficiency correction value corresponding to each moment to obtain the corrected inflation efficiency corresponding to each moment.
The operation data is recorded at each moment in the moving time period, that is, relevant data is collected at each moment, for example, the basic model inflation efficiency at the second moment is corrected by using the target inflation efficiency correction value corresponding to the second moment, so that the corrected inflation efficiency corresponding to the second moment is obtained.
In the embodiment, the moving distance and the moving duration of the motor vehicle in the moving process are obtained, and the corresponding operation data of the engine in the moving duration are collected; if the moving distance is detected to be larger than the preset distance threshold value and the moving time length is detected to be larger than the preset time length threshold value, calculating based on the operation data to obtain a target inflation efficiency correction value corresponding to each moment in the moving time length; the operation data comprise basic model inflation efficiency corresponding to each moment in the moving duration. When the moving time and the moving distance reach certain thresholds respectively, collecting the operation data in the moving time is more accurate, and accurately correcting the basic model inflation efficiency at the corresponding time based on the target inflation efficiency correction value corresponding to each time to obtain accurate corrected inflation efficiency corresponding to each time.
Referring to fig. 3, fig. 3 is a flowchart of another method for correcting inflation efficiency based on the embodiment shown in fig. 2. The operation data further comprises engine speed and a first mixture correction coefficient corresponding to each moment in the moving duration; the method further includes steps S310 to S320 in S220 shown in fig. 2, which are described in detail below:
s310: and obtaining a second mixed gas correction coefficient based on the engine speed and the basic model inflation efficiency.
In the moving process of the motor vehicle, the engine rotating speed, the basic model inflation efficiency and the first mixed gas correction coefficient corresponding to each moment in the moving duration can be directly obtained, and the second mixed gas correction coefficient corresponding to each moment is obtained through calculation according to the engine rotating speed and the basic model inflation efficiency corresponding to each moment.
S320: and obtaining a corresponding inflation efficiency correction value at each moment according to the first mixed gas correction coefficient and the second mixed gas correction coefficient.
And adjusting the first mixture correction coefficient by using the second mixture correction coefficient obtained by the calculation in the step, and obtaining the charging efficiency correction value corresponding to each moment similarly to correcting the first mixture correction coefficient corresponding to each moment.
If the motor vehicle runs in a completely ideal state, the first mixed gas correction coefficient and the second mixed gas correction coefficient are completely the same, the first mixed gas correction coefficient does not need to be corrected, and the charging efficiency correction value corresponding to each moment is directly determined according to the first mixed gas correction coefficient.
Exemplarily explaining the step S320, obtaining a difference between the second mixture correction coefficient and the first mixture correction coefficient at each moment, and averaging the difference to obtain an average difference; and adding or subtracting the average difference value according to the first mixed gas correction coefficient, so as to obtain the inflation efficiency correction value corresponding to each moment.
This embodiment further illustrates how the charging efficiency correction value is determined based on the engine speed, the base model charging efficiency, and the first mixture correction factor in the operating data. And according to the second mixed gas correction coefficient obtained by the rotating speed of the engine and the inflation efficiency of the basic model, combining the first mixed gas correction coefficient measured in real time with the second mixed gas correction coefficient obtained by theoretical calculation, and accurately determining the inflation efficiency correction value corresponding to each moment.
FIG. 4 is a flow chart of another proposed method of modifying the charging efficiency based on the embodiment shown in FIG. 2. The method further includes S410 to S420 in S230 shown in fig. 2, which are described in detail below:
s410: and adjusting the inflation efficiency of the basic model at each moment to obtain the inflation efficiency of the adjusted basic model at each moment.
During the moving process of the motor vehicle, the basic model inflation efficiency collected at each moment is not completely accurate and can be influenced by the operating conditions, so that the basic model inflation efficiency at each moment is not completely the same. In addition, because the inflation efficiency of the basic model is mainly calculated according to the oil consumption value, but the actual oil consumption value of the motor vehicle in the actual moving process is not necessarily the same as the oil consumption value acquired by the oil consumption meter, so that the inflation efficiency of the basic model at each moment is not accurate, and therefore the inflation efficiency of the basic model after adjustment at each moment needs to be adjusted to obtain the inflation efficiency of the basic model after adjustment at each moment. Wherein the adjustment process is similar to the first correction of the base model inflation efficiency.
S420: and correcting the inflation efficiency of the basic model adjusted at the corresponding time based on the inflation efficiency correction value corresponding to each time to obtain the corrected inflation efficiency corresponding to each time.
The inflation efficiency correction value is a value used for correcting the inflation efficiency of the basic model, and if the inflation efficiency of the adjusted basic model is corrected by using the inflation efficiency correction value, the process of correcting the inflation efficiency of the adjusted basic model is similar to the process of correcting the inflation efficiency of the basic model for the second time, so that the obtained corrected inflation efficiency corresponding to each moment is more accurate.
In the embodiment, the basic model inflation efficiency is corrected twice, the basic model inflation efficiency at each moment is firstly adjusted, and the adjusted basic model inflation efficiency at the corresponding moment is corrected based on the inflation efficiency correction value corresponding to each moment, so that the corrected inflation efficiency corresponding to each moment is accurately obtained.
In another exemplary embodiment, based on step S420 shown in fig. 4, the specific steps are: and performing product calculation on the inflation efficiency correction value corresponding to each moment and the adjusted inflation efficiency of the basic model corresponding to the moment to obtain the corrected inflation efficiency corresponding to each moment.
The calculation formula of this embodiment is: corrected inflation efficiency = adjusted base model inflation efficiency — inflation efficiency correction value. In some embodiments, the inflation efficiency of the base model is not adjusted, that is, the inflation efficiency of the base model and the inflation efficiency correction value are directly used to calculate the corrected inflation efficiency, that is, the corrected inflation efficiency = the inflation efficiency of the base model and the inflation efficiency correction value, and the accuracy of the corrected inflation efficiency obtained is lower than that of the corrected inflation efficiency obtained in the present embodiment.
The embodiment further clarifies the calculation process between the inflation efficiency correction value corresponding to each moment and the adjusted inflation efficiency of the basic model corresponding to the moment, and the product obtained by multiplying the inflation efficiency correction value and the adjusted inflation efficiency of the basic model is the corrected inflation efficiency.
FIG. 5 is a flow chart of another proposed method of modifying inflation efficiency based on the embodiment shown in FIG. 4. The operation data also comprises the corresponding engine speed at each moment in the moving duration; the method includes S510 to S530 in S410 shown in fig. 4, which will be described in detail below:
s510: acquiring an inflation efficiency correction Map; and the inflation efficiency correction Map is constructed based on the inflation efficiency correction value, the engine rotating speed and the inflation efficiency of the basic model.
The charging efficiency correction Map is exemplarily described, wherein the abscissa of the charging efficiency correction Map is the engine speed, and the ordinate is the charging efficiency of the basic model; or the abscissa is the inflation efficiency of the basic model, and the ordinate is the rotating speed of the engine; and filling corresponding inflation efficiency correction values in each coordinate point determined according to the horizontal and vertical coordinates, namely in the inflation efficiency correction Map, if the inflation efficiency of the basic model and the engine speed are determined, determining the corresponding inflation efficiency correction values.
S520: and adjusting the smoothness of the curve contained in the inflation efficiency correction Map to obtain the adjusted inflation efficiency correction Map.
For example, if the charging efficiency correction value filled in a certain coordinate point is obviously different from the charging efficiency correction value filled in an adjacent coordinate point, the charging efficiency correction value needs to be adjusted, and the charging efficiency correction value filled in the coordinate point is appropriately increased or decreased, so that the adjusted charging efficiency correction Map is obtained.
In some embodiments, the adjusted inflation efficiency of the basic model is used for replacing the inflation efficiency of the basic model, so that the value of the inflation efficiency of the basic model is more accurate, and the constructed inflation efficiency correction Map is more accurate.
S530: and correcting the Map based on the adjusted inflation efficiency to obtain the adjusted inflation efficiency of the basic model at each moment.
In the adjusted inflation efficiency correction Map, the engine speed and the basic model inflation efficiency are determined, and a corresponding coordinate point can be determined, so that the inflation efficiency correction value filled in the coordinate point is obtained.
The embodiment illustrates how to correct the Map based on the adjusted inflation efficiency to obtain the adjusted inflation efficiency of the basic model at each time within the moving time period. Firstly, an inflation efficiency correction Map is constructed according to the inflation efficiency correction value, the engine speed and the inflation efficiency of the basic model, and the abnormal coordinate point and the corresponding abnormal inflation efficiency correction value can be intuitively known, so that the inflation efficiency correction Map is adjusted, and the inflation efficiency of the basic model adjusted at each moment is more accurate.
FIG. 6 is a flow chart of another proposed method for modifying the inflation efficiency based on the embodiment shown in FIG. 5. Before S510, the method further includes S610 to S630, which are described in detail below:
s610: and constructing a coordinate system by taking the rotating speed of the engine as a first dimension and the inflation efficiency of the basic model as a second dimension.
The S610 is exemplarily illustrated: and taking the rotating speed of the engine as an abscissa and the inflation efficiency of the basic model as an ordinate, or taking the inflation efficiency of the basic model as an abscissa and the rotating speed of the engine as an ordinate, and constructing to obtain a coordinate system.
S620: and drawing a coordinate point in a coordinate system according to the basic model inflation efficiency corresponding to the engine rotating speed.
Filling the engine rotating speed and the basic model inflation efficiency into a coordinate system, and drawing corresponding coordinate points in the coordinate system according to the basic model inflation efficiency corresponding to the engine rotating speed. Illustratively, when the engine speed is 1000 units and the basic model charging efficiency is 200 units, the value of the first dimension in the coordinate system is 1000, and the value of the second dimension is 200, so as to determine the coordinate point of (1000, 200) or (200, 1000).
S630: and filling the inflation efficiency correction value to the coordinate point to obtain an inflation efficiency correction Map.
If the engine speed at a certain time in the travel period is 1000 units, the base model charging efficiency is 200 units, and the charging efficiency correction value is 0.8 units, the coordinate point at that time is (1000, 200), and the charging efficiency correction value is 0.8 at the coordinate point (1000, 200).
This embodiment further illustrates how the charging efficiency correction Map is constructed according to the engine speed, the basic model charging efficiency, and the charging efficiency correction value. The engine speed and the basic model inflation efficiency are respectively used as coordinate axes, the engine speed and the basic model inflation efficiency corresponding to each moment in the moving time are drawn to obtain a coordinate point, and the inflation efficiency correction value corresponding to the moment is filled in the coordinate point, so that the inflation efficiency correction Map is obtained quickly, and the related inflation efficiency correction value can be obtained more intuitively and quickly.
Fig. 7 is a flowchart of another modification method of the charging efficiency based on the embodiment shown in any one of fig. 2 to 6. The method further includes steps S710 to S730 in S220, which are described in detail below:
s710: detecting whether specified data exist in the operating data; the specified data comprises at least one of data corresponding to the starting and stopping time of the engine, data corresponding to the opening time of the carbon tank and data corresponding to the time when the air-fuel ratio is larger than a preset air-fuel ratio threshold value.
S720: and if the specified data exist in the operation data, deleting the specified data to obtain the deleted operation data.
The specified data in this embodiment are data that affect the accuracy of the inflation efficiency correction value, and if the specified data are not deleted or filtered in the process of calculating the inflation efficiency correction value, the inflation efficiency correction value will have a large deviation. For example, the charging efficiency correction value corresponding to the engine start-stop time cannot be accurately calculated from the operation data collected at the engine start-stop time, and if the operation data collected at the engine start-stop time is summarized in the total operation data, the accuracy of the charging efficiency correction value obtained by calculation will be reduced. For another example, if the air-fuel ratio corresponding to a certain time period within the moving time period is 2, and the preset air-fuel ratio threshold value is 1.5, that is, the air-fuel ratio is greater than the preset air-fuel ratio threshold value, the data corresponding to the certain time period is deleted.
S730: and calculating based on the deleted operation data to obtain a target inflation efficiency correction value corresponding to each moment in the moving time.
In this embodiment, the process of deleting the designated data is a data cleaning process, so that invalid data is well shielded, and an inflation efficiency correction value having a representative meaning is obtained.
If the specified data includes data corresponding to the start-stop time of the engine, data corresponding to the opening time of the canister, and data corresponding to the time when the air-fuel ratio is greater than the preset air-fuel ratio threshold, the operation data purging process shown in fig. 8 needs to be performed, and fig. 8 is a flowchart of the operation data purging process shown in an exemplary embodiment of the present application. Detecting whether the moment of starting and stopping the engine exists in the moving duration, and deleting data corresponding to the moment of starting and stopping the engine; detecting whether the moment when the carbon tank is opened exists in the moving time, and deleting data corresponding to the moment when the carbon tank is opened; and finally, detecting whether the air-fuel ratio is greater than a preset air-fuel ratio threshold value within the moving time length, and deleting data corresponding to the time when the air-fuel ratio is greater than the preset air-fuel ratio threshold value, thereby obtaining deleted operation data.
