[0025] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0027] At present, when the vehicle is driving, the driver can judge whether it needs to replenish energy by the vehicle's cruising range. For new energy vehicles, it is necessary to calculate the comprehensive fuel cruising range and electric energy cruising range as the vehicle's cruising range. The existing solution uses a fixed fuel consumption value to calculate the fuel cruising range, which has a certain error.

[0028] In order to solve the problems of the prior art, the embodiments of the present application provide a method, device, equipment and computer storage medium for determining the fuel mileage. The method for determining the fuel mileage provided in the embodiments of the present application is first introduced below.

[0029] Figure 1 FIG. 1 is a flow chart showing a method for determining a fuel mileage according to an embodiment of the present application. Figure 1 As shown, the method may include the following steps:

[0030] S110: Acquire a driving mode and driving operation data of the hybrid electric vehicle, where the driving operation data includes accelerator operation data and brake operation data.

[0031] The current driving mode of the hybrid electric vehicle and the driving operation data of the driver are obtained. Specifically, the driving mode of the vehicle is hybrid electric drive or pure electric drive; the driving operation data includes the driver's operation data on the accelerator and brake pedal. The operation data of the brake pedal is the driver's brake operation data.

[0032] S120: Determine a driving aggressiveness index based on the accelerator operation data and the brake operation data.

[0033] The throttle operation data includes the throttle pedal opening and the throttle pedal opening change rate, and the brake operation data includes the brake pedal opening and the brake pedal opening change rate. The driver's driving aggressiveness index is determined according to the correspondence between the preset driving aggressiveness index and the throttle and brake operation data.

[0034] S130: Determine an initial cruising range according to a preset fuel cruising range estimation strategy.

[0035] According to the preset fuel cruising range estimation strategy when the hybrid electric vehicle is driven, the mileage contributed by electric energy in the preset time period is calculated, and the mileage contributed by fuel in the preset time period is calculated according to the total mileage of the vehicle in the preset time period. The fuel consumption of the hybrid electric vehicle is calculated based on the mileage contributed by fuel and the fuel consumption, and the initial cruising range is calculated in combination with the current remaining fuel of the vehicle.

[0036] S140: When the driving mode is the pure electric driving mode, a correction coefficient corresponding to the driving aggressiveness index is determined according to a preset correspondence between the driving aggressiveness index and the correction coefficient.

[0037] When the current driving mode of the vehicle is the pure electric driving mode, the correction coefficient of the fuel range corresponding to the current driver's driving aggressiveness index is determined according to the preset corresponding relationship table of driving aggressiveness index and correction coefficient. The preset corresponding relationship table of driving aggressiveness index and correction coefficient can be determined according to historical experimental data.

[0038] S150: Correct the initial cruising range based on the correction coefficient to obtain a target cruising range.

[0039] Calculate the product of the correction coefficient and the initial cruising range to get the corrected target cruising range. For example, if the correction coefficient is 0.7 and the initial cruising range is 100 kilometers, the corrected target cruising range is 70 kilometers. The higher the driving aggressiveness index, the smaller the corresponding correction coefficient. Therefore, the higher the driving aggressiveness index, the lower the corrected target cruising range.

[0040] The method for determining the fuel range provided in the embodiment of the present application can calculate the driving aggressiveness index based on the driver's driving operation data, determine the initial range according to the fuel range estimation strategy, and further correct the initial range based on the correction coefficient corresponding to the driving aggressiveness index to obtain the target range, which can improve the accuracy of calculating the fuel range of the vehicle.

[0041] In some embodiments, determining a driving aggression index based on throttle operation data and brake operation data includes: determining a driving operation data range to which the throttle operation data and the brake operation data belong; and determining a driving aggression index corresponding to the driving operation data range according to a preset correspondence between the driving operation data range and the driving aggression index. The driving aggression index and the corresponding operation range data are stored in a preset operation data and driving aggression index correspondence table. For example, when the driving aggression index is 2, the corresponding operation data range is: throttle pedal opening range [0.7, 0.8], throttle pedal opening rate range [1, 1.2], brake pedal opening range [0.7, 0.8], brake pedal opening rate range [1, 1.2].

[0042] In some embodiments, the operation data range corresponding to the driving aggressiveness index is the throttle operation data range or the brake data range. For example, when the driving aggressiveness index is 2, the corresponding operation data range is: throttle pedal opening range [0.7, 0.8], throttle pedal opening rate range [1, 1.2], or brake pedal opening range [0.7, 0.8], brake pedal opening rate range [1, 1.2].

[0043] In some embodiments, the initial cruising range is determined according to a preset fuel cruising range estimation strategy, including: determining a first driving range contributed by electric energy within a preset time period according to the total power consumption and power consumption of the hybrid electric vehicle within a preset time period; determining a second driving range contributed by fuel within a preset time period according to the first driving range and the total driving range of the hybrid electric vehicle within a preset time period; determining the fuel consumption within a preset time period according to the second driving range and the fuel consumption of the hybrid electric vehicle within a preset time period; and determining the fuel cruising range according to the fuel consumption. In the case where the driving mode is the hybrid driving mode, the first driving range contributed by electric energy within a preset time period is determined according to the total power consumption and power consumption of the hybrid electric vehicle within a preset time period; determining a second driving range contributed by fuel within a preset time period according to the first driving range and the total driving range of the hybrid electric vehicle within a preset time period; determining the fuel consumption within a preset time period according to the second driving range and the fuel consumption of the hybrid electric vehicle within a preset time period; and estimating the initial cruising range of fuel according to the fuel consumption.

[0044] For example, assume that in the hybrid driving mode, the hybrid vehicle travels a total of 20 kilometers within 10 minutes. The total power consumption is 2% of the total battery power, and the power consumption is 20% of the total battery power per 100 kilometers. The fuel consumption is 1 liter.

[0045] The mileage contributed by electric energy within 10 minutes = 100 kilometers / 20%*2% = 10 kilometers.

[0046] The mileage contributed by electric energy within 10 minutes = 20 kilometers - 10 kilometers = 10 kilometers.

[0047] Fuel consumption within 10 minutes = 10 kilometers / 1 liter = 10 (kilometers per liter), that is, the fuel consumption is 10 liters of fuel per 100 kilometers.

[0048] Then, based on the fuel consumption of "10 liters per 100 kilometers" and the remaining fuel, estimate the fuel range.

[0049] Assuming that the remaining fuel volume is 53 liters, the estimated fuel range is 53 liters * 10 liters of fuel per 100 kilometers = 530 kilometers.

[0050] In some embodiments, determining the fuel cruising range based on the fuel consumption includes: determining a comprehensive fuel consumption for estimating the fuel cruising range based on the fuel consumption and the historical fuel consumption; and determining the fuel cruising range based on the comprehensive fuel consumption. The fuel consumption and the historical fuel consumption are weighted to obtain the comprehensive fuel consumption of the fuel cruising range. The historical fuel consumption may be an average value of the fuel consumption in multiple historical time periods. The fuel cruising range is estimated based on the remaining fuel of the hybrid electric vehicle and the comprehensive fuel consumption.

[0051] In some embodiments, when the driving mode is the pure electric driving mode, determining the correction coefficient corresponding to the driving aggression index includes: when the driving mode is the pure electric driving mode, calculating the difference between the driving aggression index and the pre-stored driving aggression index of the hybrid driving mode; determining the correction coefficient corresponding to the difference according to the preset correspondence between the difference and the correction coefficient. When the driving mode of the automobile is the pure electric driving mode, calculating the difference between the driver's driving aggression index and the pre-stored driving aggression index of the hybrid driving mode, and determining the corresponding correction coefficient according to the difference in the preset correspondence table between the difference of the driving aggression index and the correction coefficient. For example, when the difference of the driving aggression index is 0.5, the corresponding correction coefficient is 0.7. The correction coefficient may also correspond to the difference range of the driving aggression index, for example, the difference range of the driving aggression index is [0.4, 0.5], and the corresponding correction coefficient is 0.7. The pre-stored driving aggression index of the hybrid driving mode is the driving aggression index of the hybrid driving mode before the automobile switches to the current pure electric driving mode.

[0052] In some embodiments, the throttle operation data includes the throttle pedal opening and the throttle pedal opening change rate; the brake operation data includes the brake pedal opening and the brake pedal opening change rate.

[0053] In some embodiments, the method further includes: when the driving mode is a hybrid driving mode, determining the initial cruising range as the target cruising range.

[0054] The method for determining the fuel range provided in the embodiment of the present application can calculate the driving aggressiveness index based on the driver's driving operation data such as the opening data of the accelerator pedal and the brake pedal, and further correct the initial range of the car determined according to the fuel range estimation strategy based on the correction coefficient corresponding to the driving aggressiveness index to obtain the fuel range of the car, which can improve the accuracy of calculating the fuel range of the car.
