[0050] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0051] The embodiment of the present invention provides a method for calculating the comprehensive fuel consumption of a hybrid vehicle, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for calculating the comprehensive fuel consumption of a hybrid vehicle according to the present invention.

[0052] In this embodiment, the hybrid vehicle comprehensive fuel consumption calculation method includes the following steps:

[0053] Step S10: using the percentile method to filter the instantaneous fuel consumption rate within the driving mileage to obtain the filtered instantaneous fuel consumption rate.

[0054] It should be noted that the execution subject of this embodiment can be a computer server device used in a hybrid electric vehicle with data processing, network communication, and program execution functions, such as an on-board control device, or an electronic device capable of implementing the above functions, a hybrid vehicle comprehensive fuel consumption calculation device, etc. The following uses a hybrid vehicle comprehensive fuel consumption calculation system (hereinafter referred to as the system) that includes a hybrid vehicle comprehensive fuel consumption calculation device as an example to illustrate this embodiment and the following embodiments.

[0055] It should be understood that before step S10, it also includes: obtaining the power consumption (kilowatt-hour, kWh), mileage (kilometers, km), fuel consumption (liters, L) and instantaneous fuel injection amount within a preset time period, and accumulating the instantaneous fuel injection amount within the mileage to obtain the total fuel injection amount.

[0056] It is understandable that this embodiment and the following embodiments are applied to hybrid electric vehicles, which include series hybrid electric vehicles and series-parallel hybrid electric vehicles.

[0057] It should be explained that the percentile method is to sort a set of data from small to large and calculate the corresponding cumulative percentile. The value of the data corresponding to a certain percentile is called the percentile of that percentile. In simple terms, it is to divide a set of data into 100 equal parts, each containing the same number of data points (when the amount of data is not an integer multiple of 100, the number of data points in some parts will be slightly different), and then find the boundary values ​​of each part. These boundary values ​​are percentiles.

[0058] In a specific implementation, two percentiles may be selected as the lower and upper screening boundaries of the instantaneous fuel consumption rate, and then data of the instantaneous fuel consumption rate may be filtered based on the lower and upper screening boundaries.

[0059] It should be noted that the instantaneous fuel consumption rate F rate =Instantaneous fuel injection amount / ((Engine speed×Engine torque) / 9550).

[0060] The instantaneous injection volume refers to the amount of fuel injected into the cylinder through the injector at a specific moment in the engine. This value is determined by the engine management system (ECU) based on the current engine operating conditions (such as speed, load, intake volume, etc.) and the preset injection strategy.

[0061] Step S20: obtaining a central instantaneous fuel consumption rate, an instantaneous fuel consumption rate standard deviation, and an average instantaneous fuel consumption rate according to the filtered instantaneous fuel consumption rate.

[0062] It is understandable that the central instantaneous fuel consumption rate, the instantaneous fuel consumption rate standard deviation and the average instantaneous fuel consumption rate can be directly calculated based on the filtered instantaneous fuel consumption rates according to the median, standard deviation and average calculation methods in mathematical calculations.

[0063] Step S30: selecting an equivalent conversion factor calculation formula based on the relationship between the central instantaneous fuel consumption rate, the instantaneous fuel consumption rate standard deviation, and the average instantaneous fuel consumption rate, and determining an equivalent conversion factor based on the equivalent conversion factor calculation formula.

[0064] It should be understood that the above equivalent conversion factor is a key parameter for converting the power consumption of a hybrid electric vehicle within a driving range into equivalent fuel consumption.

[0065] It should be noted that the relationship between the center instantaneous fuel consumption rate, the instantaneous fuel consumption rate standard deviation, and the average instantaneous fuel consumption rate may be determined by whether the average instantaneous fuel consumption rate is greater than or equal to the difference between the center instantaneous fuel consumption rate and the instantaneous fuel consumption rate standard deviation, and whether the average instantaneous fuel consumption rate is less than or equal to the sum of the center instantaneous fuel consumption rate and the instantaneous fuel consumption rate standard deviation.

[0066] In a specific implementation, it can be determined whether the average instantaneous fuel consumption rate is greater than or equal to the difference between the center instantaneous fuel consumption rate and the standard deviation of the instantaneous fuel consumption rate, and the average instantaneous fuel consumption rate is less than or equal to the sum of the center instantaneous fuel consumption rate and the standard deviation of the instantaneous fuel consumption rate; if so, the first preset formula is used as the equivalent conversion factor calculation formula; if not, the second preset formula is used as the equivalent conversion factor calculation formula; wherein, the first preset formula is: equivalent conversion factor = fuel consumption / total fuel injection amount × center instantaneous fuel consumption rate; wherein, the second preset formula is: equivalent conversion factor = fuel consumption / total fuel injection amount × average instantaneous fuel consumption rate.

[0067] For example, when center instantaneous fuel consumption - instantaneous fuel consumption standard deviation ≤ average instantaneous fuel consumption ≤ center instantaneous fuel consumption + instantaneous fuel consumption standard deviation, the equivalent conversion factor = fuel consumption / total fuel injection amount × center instantaneous fuel consumption; otherwise, the equivalent conversion factor = fuel consumption / total fuel injection amount × average instantaneous fuel consumption.

[0068] Step S40: Calculating a comprehensive fuel consumption value based on the power consumption, the fuel consumption and the equivalent conversion factor.

[0069] It should be noted that the electric power consumption equivalent fuel consumption value may be determined based on the electric power consumption and the equivalent conversion factor, for example, the electric power consumption equivalent fuel consumption value=electric power consumption×equivalent conversion factor.

[0070] It is understandable that, since the average fuel consumption is usually calculated using fuel consumption per 100 kilometers (ie, fuel consumption / mileage×100), this embodiment also uses the comprehensive fuel consumption value per 100 kilometers to calculate.

[0071] In a specific implementation, the electric power consumption equivalent fuel consumption value is determined based on the electric power consumption and the equivalent conversion factor; based on the comprehensive fuel consumption calculation formula, the comprehensive fuel consumption value is calculated through the fuel consumption, the electric power consumption equivalent fuel consumption value and the mileage; wherein, the comprehensive fuel consumption calculation formula is: comprehensive fuel consumption value = (fuel consumption + electric power consumption equivalent fuel consumption value) / mileage × 100.

[0072] This embodiment discloses a method for filtering instantaneous fuel consumption data within a driving range using a percentile method to obtain a filtered instantaneous fuel consumption rate; obtaining a central instantaneous fuel consumption rate, a standard deviation of the instantaneous fuel consumption rate, and an average instantaneous fuel consumption rate based on the filtered instantaneous fuel consumption rate; selecting an equivalent conversion factor calculation formula based on the relationship between the central instantaneous fuel consumption rate, the standard deviation of the instantaneous fuel consumption rate, and the average instantaneous fuel consumption rate, and determining an equivalent conversion factor based on the equivalent conversion factor calculation formula; and calculating a comprehensive fuel consumption value based on power consumption, fuel consumption, and the equivalent conversion factor. Because this embodiment uses the percentile method to filter instantaneous fuel consumption data within a driving range, then determines an equivalent conversion factor based on the central instantaneous fuel consumption rate, the standard deviation of the instantaneous fuel consumption rate, and the average instantaneous fuel consumption rate of the filtered instantaneous fuel consumption rate, and finally calculates a comprehensive fuel consumption value based on the equivalent conversion factor, compared to existing technologies, this embodiment comprehensively considers both power consumption and fuel consumption of a hybrid vehicle, reducing confusion for users when viewing the consumption information of a hybrid vehicle, thereby improving user satisfaction with the hybrid vehicle.

[0073] refer to Figure 2 , Figure 2 This is a flow chart of the second embodiment of the method for calculating the comprehensive fuel consumption of a hybrid vehicle according to the present invention.

[0074] Based on the first embodiment above, in this embodiment, step S10 includes:

[0075] Step S101: determining the instantaneous fuel consumption rate within the mileage according to the instantaneous fuel injection amount, engine speed and engine torque within the mileage.

[0076] It should be noted that the instantaneous fuel consumption rate F rate =Instantaneous fuel injection amount / ((Engine speed×Engine torque) / 9550).

[0077] Step S102: selecting a non-zero instantaneous fuel consumption rate from the instantaneous fuel consumption rates, and determining a screening lower boundary and a screening upper boundary using a percentile method.

[0078] In order to improve the accuracy of the comprehensive energy consumption calculation and improve the calculation efficiency, a non-zero instantaneous fuel consumption rate can be first selected from the instantaneous fuel consumption rates, and then the percentile method is used to determine the screening lower boundary and the screening upper boundary from the non-zero instantaneous fuel consumption rates.

[0079] It should be noted that a non-zero instantaneous fuel consumption rate can be selected from the instantaneous fuel consumption rates; a value at a first preset percentile is determined, and the value at the first preset percentile is used as the lower screening boundary for the non-zero instantaneous fuel consumption rate; a value at a second preset percentile is determined, and the value at the second preset percentile is used as the upper screening boundary for the non-zero instantaneous fuel consumption rate.

[0080] It is understandable that the first preset percentile and the second preset percentile may be user-defined settings, and this embodiment does not limit this.

[0081] Step S103: performing data screening on the non-zero instantaneous fuel consumption rate based on the screening lower boundary and the screening upper boundary to obtain the screened instantaneous fuel consumption rate.

[0082] In a specific implementation, the value at the p% (which can be calibrated, i.e., the first preset percentile) position is obtained, i.e., the pth percentile F p , as the lower boundary of the screening of non-zero instantaneous fuel consumption rate; find the value at the q% (calibrable, that is, the second preset percentile) position, that is, the qth percentile F q , as the upper limit of the screening of non-zero instantaneous fuel consumption rate; where p<q; the data of non-zero instantaneous fuel consumption rate is screened, that is, F p ≤F rate ≤F q , obtain the filtered instantaneous fuel consumption rate.

[0083] This embodiment discloses determining an instantaneous fuel consumption rate within a mileage based on an instantaneous fuel injection amount, an engine speed, and an engine torque within the mileage; selecting a non-zero instantaneous fuel consumption rate from the instantaneous fuel consumption rates, and determining a lower screening boundary and an upper screening boundary using a percentile method; performing data screening on the non-zero instantaneous fuel consumption rates based on the lower screening boundary and the upper screening boundary to obtain a screened instantaneous fuel consumption rate; obtaining a central instantaneous fuel consumption rate, an instantaneous fuel consumption rate standard deviation, and an average instantaneous fuel consumption rate based on the screened instantaneous fuel consumption rate; selecting an equivalent conversion factor calculation formula based on the relationship between the central instantaneous fuel consumption rate, the instantaneous fuel consumption rate standard deviation, and the average instantaneous fuel consumption rate, and determining an equivalent conversion factor based on the equivalent conversion factor calculation formula; and calculating a comprehensive fuel consumption value based on power consumption, fuel consumption, and the equivalent conversion factor. Compared to the prior art, this embodiment selects non-zero instantaneous fuel consumption rates from the instantaneous fuel consumption rates and uses the percentile method to determine the lower and upper screening boundaries. Data screening of the non-zero instantaneous fuel consumption rates is performed based on the lower and upper screening boundaries, thereby not only improving the accuracy of subsequent comprehensive energy consumption calculations but also further improving computational efficiency.

[0084] refer to Figure 3 , Figure 3 This is a flow chart of the third embodiment of the method for calculating the comprehensive fuel consumption of a hybrid vehicle according to the present invention.

[0085] Based on the above embodiments, in this embodiment, step S20 includes:

[0086] Step S201: according to the filtered instantaneous fuel consumption rate, a normal distribution method is used to obtain a central instantaneous fuel consumption rate and a standard deviation of the instantaneous fuel consumption rate.

[0087] Step S202: Calculate the average value of the filtered instantaneous fuel consumption rates, and use the average value as the average instantaneous fuel consumption rate.

[0088] It should be noted that the normal distribution method is applicable not only to continuous data but also to discrete data (under appropriate conditions). While conventional mathematical calculations can also process both types of data, the normal distribution method more accurately reflects the distribution characteristics of continuous data. While the central value and standard deviation obtained through conventional mathematical calculations can describe certain characteristics of the data, they may be limited when performing statistical inference. Therefore, this embodiment utilizes the normal distribution method to obtain the central instantaneous fuel consumption rate and the standard deviation of the instantaneous fuel consumption rate after screening, further improving the accuracy and reliability of subsequent comprehensive energy consumption calculations.

[0089] This embodiment discloses a method for filtering instantaneous fuel consumption data within a driving range using a percentile method to obtain filtered instantaneous fuel consumption; based on the filtered instantaneous fuel consumption, obtaining a central instantaneous fuel consumption and a standard deviation of the filtered instantaneous fuel consumption using a normal distribution method; calculating an average of the filtered instantaneous fuel consumption and using the average as the average instantaneous fuel consumption; selecting an equivalent conversion factor calculation formula based on the relationship between the central instantaneous fuel consumption, the standard deviation of the instantaneous fuel consumption, and the average instantaneous fuel consumption, and determining an equivalent conversion factor based on the equivalent conversion factor calculation formula; and calculating a comprehensive fuel consumption value based on power consumption, fuel consumption, and the equivalent conversion factor. Because this embodiment uses the normal distribution method to obtain the central instantaneous fuel consumption and the standard deviation of the filtered instantaneous fuel consumption, it can more accurately reflect the distribution characteristics of the data compared to ordinary mathematical calculations using the normal distribution method, thereby further improving the accuracy and reliability of subsequent comprehensive energy consumption calculations.

[0090] In addition, an embodiment of the present invention further proposes a storage medium, on which a hybrid vehicle comprehensive fuel consumption calculation program is stored. When the hybrid vehicle comprehensive fuel consumption calculation program is executed by a processor, the steps of the hybrid vehicle comprehensive fuel consumption calculation method described above are implemented.

[0091] Reference Figure 4 , Figure 4 This is a structural block diagram of the first embodiment of the hybrid vehicle comprehensive fuel consumption calculation device of the present invention.

[0096] The energy consumption calculation module 404 is used to calculate the comprehensive fuel consumption value according to the power consumption, fuel consumption and the equivalent conversion factor.

[0097] The conversion factor determination module 403 is further configured to determine whether the average instantaneous fuel consumption rate is greater than or equal to the difference between the center instantaneous fuel consumption rate and the standard deviation of the instantaneous fuel consumption rate, and whether the average instantaneous fuel consumption rate is less than or equal to the sum of the center instantaneous fuel consumption rate and the standard deviation of the instantaneous fuel consumption rate; if so, a first preset formula is used as the equivalent conversion factor calculation formula; if not, a second preset formula is used as the equivalent conversion factor calculation formula.

[0098] The data screening module 401 is further configured to obtain power consumption, mileage, fuel consumption, and instantaneous fuel injection amount within a preset time period, and accumulate the instantaneous fuel injection amount within the mileage to obtain a total fuel injection amount.

[0099] The energy consumption calculation module 404 is further configured to determine an electric power consumption equivalent fuel consumption value based on the electric power consumption and the equivalent conversion factor; and calculate a comprehensive fuel consumption value based on the comprehensive fuel consumption calculation formula using the fuel consumption, the electric power consumption equivalent fuel consumption value, and the mileage.
