Certainly, the method may also be applied to other implementation environments, and executed by server devices in other implementation environments, which is not limited in this embodiment. As shown in FIG. 2, the method includes at least S210 to S230, and the details are as follows:

S210: Acquire the moving distance and the moving duration during the movement of the motor vehicle, and collect the operation data corresponding to the engine within the moving duration.

Motor vehicles include fuel vehicles, fuel-electric hybrid vehicles and other fuel-consuming vehicles.

The operating data includes the engine speed, the basic model charging efficiency, the engine load, the fuel injection amount and other data during the operation of the motor vehicle.

S220: If it is detected that the moving distance is greater than the preset distance threshold, and the moving duration is greater than the preset duration threshold, calculating based on the running data to obtain the target inflation efficiency correction value corresponding to each moment in the moving duration; wherein, the running data includes the moving duration The basic model inflation efficiency corresponding to each time in the

The preset distance threshold and the preset duration threshold are preset thresholds set according to motor vehicles of different models and performances, that is, for different motor vehicles, the set preset thresholds may have different sizes.

The inflation efficiency of the basic model is calculated according to the fuel consumption data during the calibration process of the bench. The inflation efficiency of the basic model corresponding to each moment in this embodiment is an actual value. It is corrected by the target restart efficiency correction value, and the corrected charging efficiency has been obtained.

S220 is exemplarily explained, 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 their corresponding preset thresholds, Then, the inflation efficiency of the basic model corresponding to each moment is calculated by using the operation data collected during the movement duration.

S230: Based on the target inflation efficiency correction value corresponding to each time, correct the basic model inflation efficiency at the corresponding time to obtain the corrected inflation efficiency corresponding to each time.

The operation data is recorded at each moment in the moving duration, that is, relevant data is collected at each moment. For example, the inflation efficiency of the basic model at the second moment is corrected by using the target inflation efficiency correction value corresponding to the second moment. The corrected inflation efficiency corresponding to the second moment is obtained.

In this embodiment, the movement distance and movement duration of the motor vehicle during the movement process are acquired, and the operation data corresponding to the engine within the movement duration is collected; if it is detected that the movement distance is greater than the preset distance threshold and the movement duration is greater than the preset duration threshold, the The operation data is calculated to obtain the target inflation efficiency correction value corresponding to each moment in the moving duration; wherein, the operational data includes the basic model inflation efficiency corresponding to each moment in the moving duration. When the movement duration and movement distance reach a certain threshold, the operation data collected within the movement duration is more accurate, and based on the target inflation efficiency correction value corresponding to each moment, the basic model inflation efficiency at the corresponding moment is accurately corrected to obtain accurate The corrected inflation efficiency corresponding to each time of .

Please refer to FIG. 3 . FIG. 3 is a flowchart of another method for correcting inflation efficiency based on the embodiment shown in FIG. 2 . Wherein, the operation data also includes the engine speed and the first mixture correction coefficient corresponding to each moment in the moving duration; the method also includes S310 to S320 in S220 shown in FIG. 2 , which will be described in detail below:

S310: Obtain a second air-fuel mixture correction coefficient based on the engine speed and the basic model charging efficiency.

During the movement of the motor vehicle, the engine speed, the basic model charging efficiency and the first mixture correction coefficient corresponding to each moment in the moving duration can be directly obtained. The second mixture correction factor of .

S320: Obtain a correction value of the charging efficiency corresponding to each moment according to the first gas mixture correction coefficient and the second gas mixture correction coefficient.

Adjusting the first mixture correction coefficient by using the second mixture correction coefficient calculated in the above steps is similar to correcting the first mixture correction coefficient corresponding to each moment to obtain the correction value of the charging efficiency corresponding to each moment.

If the motor vehicle runs in a completely ideal state, the first mixture correction coefficient and the second mixture correction coefficient are exactly the same, so the first mixture correction coefficient does not need to be corrected, and the first mixture correction coefficient is determined directly according to the first mixture correction coefficient. The correction value of the inflation efficiency corresponding to each time.

S320 is exemplarily described, obtaining the difference between the second gas mixture correction coefficient and the first gas mixture correction coefficient at each moment, and averaging the difference to obtain the average difference; Addition and subtraction of the value, and then obtain the correction value of the inflation efficiency corresponding to each moment.

The second mixture correction coefficient is obtained according to the engine speed and the basic model charging efficiency, and the first mixture correction coefficient measured in real time is combined with the theoretically calculated second mixture correction coefficient to accurately determine the corresponding time. The inflation efficiency correction value of .

FIG. 4 is a flowchart of another method for correcting inflation efficiency proposed based on the embodiment shown in FIG. 2 . The method further includes S410 to S420 in S230 as shown in FIG. 2 , which will be described in detail below:

S410: Adjust the inflation efficiency of the basic model at each time to obtain the adjusted inflation efficiency of the basic model at each time.

During the movement of the motor vehicle, the inflation efficiency of the basic model collected at each moment is not completely accurate, and it will be affected by the operating conditions, so the inflation efficiency of the basic model at each moment is not exactly the same. In addition, because the inflation efficiency of the basic model is mainly calculated based on the fuel consumption value, the actual fuel consumption value of the motor vehicle during the actual moving process and the fuel consumption value collected by the fuel consumption meter are not necessarily the same, resulting in the inflation of the basic model at each moment. The efficiency is not accurate, so it needs to be adjusted to get the base model inflation efficiency adjusted at each moment. Among them, the adjustment process is similar to the first correction to the inflation efficiency of the base model.

S420: Based on the correction value of the inflation efficiency corresponding to each time, the basic model inflation efficiency adjusted at the corresponding time is corrected to obtain the corrected inflation efficiency corresponding to each time.

The inflation efficiency correction value is a value used to correct the inflation efficiency of the basic model. If it is used to correct the inflation efficiency of the adjusted basic model, the process of modifying the inflation efficiency of the basic model after adjustment is similar to the inflation efficiency of the basic model. For the second correction, the corrected inflation efficiency corresponding to each moment obtained will be more accurate.

In this embodiment, two corrections are made to the inflation efficiency of the basic model. First, the inflation efficiency of the basic model at each moment is adjusted, and then based on the inflation efficiency correction value corresponding to each moment, the inflation efficiency of the basic model adjusted at the corresponding moment is corrected. Thus, the corrected inflation efficiency corresponding to each moment can be accurately obtained.

In another exemplary embodiment, based on S420 shown in FIG. 4 , the specific steps are: multiplying the inflation efficiency correction value corresponding to each moment and the basic model inflation efficiency adjusted at the corresponding moment to obtain each moment Correspondingly corrected inflation efficiency.

The calculation formula of this embodiment: Corrected inflation efficiency=adjusted basic model inflation efficiency*inflated efficiency correction value. In some embodiments, the basic model inflation efficiency is not adjusted, that is, the modified inflation efficiency is directly calculated by using the basic model inflation efficiency and the inflation efficiency correction value, that is, the corrected inflation efficiency = the basic model inflation efficiency * the inflation efficiency correction value, which obtains The accuracy of the corrected inflation efficiency of is lower than the accuracy of the corrected inflation efficiency obtained in this embodiment.

This embodiment further clarifies the calculation process between the inflation efficiency correction value corresponding to each time and the basic model inflation efficiency adjusted at the corresponding time. By multiplying the inflation efficiency correction value and the adjusted basic model inflation efficiency, the obtained The product is the corrected inflation efficiency.

FIG. 5 is a flowchart of another method for correcting inflation efficiency proposed based on the embodiment shown in FIG. 4 . Wherein, the operation data also includes the engine speed corresponding to each moment in the moving duration; the method includes S510 to S530 in S410 as shown in FIG. 4 , which will be described in detail below:

S510 : Obtain a charge efficiency correction Map; wherein, the charge efficiency correction Map is constructed based on the charge efficiency correction value, the engine speed and the charge efficiency of the basic model.

An exemplary illustration of the charging efficiency correction Map is given. In the charging efficiency correction Map, the abscissa is the engine speed, and the ordinate is the basic model charging efficiency; or the abscissa is the basic model charging efficiency, and the ordinate is the engine speed; The determined coordinate points are filled with the corresponding charging efficiency correction value, that is, in the charging efficiency correction Map, if the basic model charging efficiency and engine speed are determined, the corresponding charging efficiency correction value can be determined.

S520: Adjust the smoothness of the curve included in the inflation efficiency correction Map to obtain the adjusted inflation efficiency correction Map.

Each coordinate point in the inflation efficiency correction map is connected as a curve. The map is subject to the requirements of smoothness and limit, and the related curve needs to be adjusted for smoothness. The inflation efficiency correction value filled in the coordinate point needs to be adjusted, and the inflation efficiency correction value filled in the coordinate point is appropriately increased or decreased to obtain the adjusted inflation efficiency correction Map.

In some embodiments, the adjusted inflation efficiency of the basic model is used to replace the inflation efficiency of the basic model, so that the value of the inflation efficiency of the basic model will be more accurate, so that the constructed inflation efficiency correction Map will be more accurate.

S530: 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 charging efficiency correction Map, the engine speed and the basic model charging efficiency are determined, and the corresponding coordinate point can be determined, so as to obtain the charging efficiency correction value filled in the coordinate point, because each moment in the moving duration Corresponding to the engine speed and the charging efficiency of the base model, and correcting the Map according to the adjusted charging efficiency, the adjusted charging efficiency of the base model at each moment can be determined.

This 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 moment in the moving duration. Firstly, according to the correction value of the charging efficiency, the engine speed and the basic model charging efficiency, the charging efficiency correction Map is constructed, which can intuitively know the abnormal coordinate points and their corresponding abnormal charging efficiency correction values, so as to adjust the charging efficiency correction Map so as to adjust the charging efficiency at each time. After the base model inflation efficiency is more accurate.

FIG. 6 is a flowchart of another method for correcting inflation efficiency proposed based on the embodiment shown in FIG. 5 . Before S510, the method further includes S610 to S630, which are described in detail below:

S610: Construct a coordinate system with the engine speed as the first dimension and the basic model inflation efficiency as the second dimension.

S610 is exemplarily explained: take the engine speed as the abscissa and the basic model inflation efficiency as the ordinate, or take the basic model inflation efficiency as the abscissa and the engine speed as the ordinate to construct a coordinate system.

S620: Draw coordinate points in the coordinate system according to the basic model charging efficiency corresponding to the engine speed.

Fill the engine speed and the basic model charging efficiency into the coordinate system, and in the coordinate system, draw the corresponding coordinate points according to the basic model charging efficiency corresponding to the engine speed. Exemplarily, if 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 (1000, 200 ) or the coordinate point of (200, 1000).

S630: Fill the inflation efficiency correction value to the coordinate point to obtain the inflation efficiency correction Map.

Fill in the corresponding inflation efficiency correction value in the coordinate point. For example, the engine speed is taken as the abscissa, and the basic model inflation efficiency is taken as the ordinate. If the engine speed corresponding to a certain moment in the moving duration is 1000 units, the basic model inflation efficiency is 200 units. unit, the inflation efficiency correction value is 0.8 units, then the corresponding coordinate point at this moment is (1000, 200), and the inflation efficiency correction value 0.8 is filled in the coordinate point (1000, 200).

This embodiment further describes how to construct and obtain the charge efficiency correction Map according to the engine speed, the basic model charge efficiency and the charge efficiency correction value. By taking the engine speed and the basic model charging efficiency as the coordinate axes respectively, and drawing the engine speed and the basic model charging efficiency corresponding to each moment in the moving duration, the coordinate points are obtained, and the correction value of the charging efficiency corresponding to this moment is filled in the coordinate points. , so as to quickly obtain the correction Map of the inflation efficiency, and more intuitively and quickly obtain the relevant correction value of the inflation efficiency.

S720: If it is detected that the specified data exists in the running data, the specified data is deleted to obtain the deleted running data.

The specified data in this embodiment refers to data that affects the accuracy of the inflation efficiency correction value. If the specified data is not deleted or filtered during the calculation of the inflation efficiency correction value, the inflation efficiency correction value will have a large deviation. For example, the operation data collected at the time of starting and stopping the engine cannot accurately calculate the correction value of the charging efficiency corresponding to the time of starting and stopping the engine. The accuracy of the calculated inflation efficiency correction will be reduced. For another example, if the air-fuel ratio corresponding to a certain duration within the moving duration is 2, and the preset air-fuel ratio threshold is 1.5, that is, the air-fuel ratio is greater than the preset air-fuel ratio threshold, the data corresponding to the duration is deleted.

S730: Perform calculation based on the deleted operation data to obtain the target inflation efficiency correction value corresponding to each moment in the moving duration.

In this embodiment, the process of deleting the specified data is a data cleaning process, which realizes good shielding of invalid data, and obtains a representative correction value of inflation efficiency.

If the specified data includes the data corresponding to the engine start-stop time, the data corresponding to the carbon canister opening time, and the data corresponding to the time when the air-fuel ratio is greater than the preset air-fuel ratio threshold, it is necessary to perform the operation data cleaning process as shown in Figure 8. Figure 8 This is a flowchart of an operation data cleaning process shown in an exemplary embodiment of the present application. Among them, firstly detect whether there is an engine start and stop time within the moving duration, delete the data corresponding to the engine start and stop time; then detect whether there is a carbon canister opening time within the moving duration, delete the data corresponding to the carbon canister opening time; finally detect the moving duration When the internal air-fuel ratio is greater than the preset air-fuel ratio threshold, the data corresponding to the time when the air-fuel ratio is greater than the preset air-fuel ratio threshold is deleted, so as to obtain the deleted operation data.

The Map is updated to obtain the corrected inflation efficiency corresponding to the update time. The specific process is shown in FIG. 10 , and FIG. 10 is a flowchart of an operation data collection process shown in an exemplary embodiment of the present application.

If it is detected that the moving distance is greater than the preset distance threshold and the moving duration is greater than the preset duration threshold, the collection of running data is stopped, the running data collected within the moving duration is summarized, and then the moving distance and duration are reset to zero.
