[0002] The vehicle's cruising range plays an important role in guiding the driver in determining whether the vehicle currently needs to be replenished with energy.

[0065] 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.

[0066] 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.

[0067] The following, in conjunction with the accompanying drawings, describes in detail the range estimation method, device, equipment, medium and product provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0068] Figure 1 is a flow chart of a method for estimating the range of a vehicle provided in an embodiment of the present application. Figure 1 As shown, the range estimation method may include:

[0069] S101: Acquire a driving mode of a hybrid electric vehicle;

[0070] S102: Estimate the fuel range according to the fuel range estimation strategy corresponding to the driving mode.

[0071] The specific implementation of each of the above steps will be described in detail below.

[0072] In the embodiment of the present application, the driving mode of the hybrid electric vehicle is obtained, and then the fuel range is estimated according to the fuel range estimation strategy corresponding to the obtained driving mode of the hybrid electric vehicle. In this way, the fuel range can be estimated according to the fuel range estimation strategy corresponding to the obtained driving mode of the hybrid electric vehicle, which can improve the accuracy of the estimated fuel range.

[0073] In some possible implementations of the embodiments of the present application, the driving modes of the hybrid electric vehicle in the embodiments of the present application include but are not limited to: hybrid driving mode, fuel-only driving mode (i.e., pure oil driving mode), and battery-only driving mode (i.e., pure electric driving mode).

[0074] The embodiment of the present application does not limit the method used to obtain the driving mode of the hybrid electric vehicle, and any available method can be applied to the embodiment of the present application.

[0075] In some possible implementations of the embodiments of the present application, S102 may include: when the driving mode is a hybrid driving mode, determining a first driving mileage 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 mileage contributed by fuel within a preset time period according to the first driving mileage and the total driving mileage of the hybrid electric vehicle within the preset time period; determining the fuel consumption within the preset time period according to the second driving mileage and the fuel consumption of the hybrid electric vehicle within the preset time period; and estimating the fuel range according to the determined fuel consumption.

[0076] For example, assume that in the hybrid driving mode, the hybrid vehicle travels 20 kilometers in 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.

[0077] The mileage contributed by electric energy within 10 minutes = 100 kilometers / 20%*2% = 10 kilometers.

[0078] The mileage contributed by electric energy within 10 minutes = 20 kilometers - 10 kilometers = 10 kilometers.

[0079] 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.

[0080] Then, the fuel range is estimated based on the determined fuel consumption of "10 liters per 100 kilometers" and the remaining fuel amount.

[0081] 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.

[0082] In some possible implementations of the embodiments of the present application, S102 may include: when the driving mode is a fuel-only driving mode, determining the amount of fuel used for battery charging within a preset time period based on the change in battery power and the oil-to-electric conversion rate of the hybrid electric vehicle within a preset time period; determining the amount of fuel used to drive the vehicle within a preset time period based on the amount of fuel and the total fuel consumption of the hybrid electric vehicle within a preset time period; determining the fuel consumption within a preset time period based on the fuel consumption and the total mileage of the hybrid electric vehicle within a preset time period; and estimating the fuel range based on the determined fuel consumption.

[0083] The oil-to-electricity conversion rate is the fuel consumption per 1% of the total power of the battery when the battery is charged with fuel.

[0084] For example, assume that in the pure oil driving mode (i.e., fuel-only driving mode), the hybrid electric vehicle travels a total of 20 kilometers within 10 minutes. Among them, the battery power increases by 2% of the total battery power, and the oil-to-electricity conversion rate is when the battery is charged with fuel, and each 1% of the total battery power is charged, and 0.5 liters of fuel is consumed. The fuel consumption is 3 liters.

[0085] Then the amount of fuel used to charge the battery within 10 minutes is = 1 liter.

[0086] The amount of fuel used to drive the car within 10 minutes = 3 liters - 1 liter = 2 liters.

[0087] Fuel consumption within 10 minutes = 20 kilometers / 2 liters = 10 (kilometers per liter), that is, the fuel consumption is 10 liters per 100 kilometers.

[0088] Then, the fuel range is estimated based on the determined fuel consumption of "10 liters per 100 kilometers" and the remaining fuel amount.

[0089] 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.

[0090] In some possible implementations of the embodiments of the present application, for an extended-range hybrid electric vehicle, when the hybrid electric vehicle operates in a pure electric drive mode, the vehicle's fuel will be converted into electrical energy to charge the vehicle's battery. Based on this, S102 may include: when the drive mode is a battery-only drive mode, determining the total power consumption within a preset time period based on the total mileage and power consumption of the hybrid electric vehicle within a preset time period; determining the charging power of the battery within a preset time period based on the total power consumption and the change in battery power within a preset time period; determining a third mileage of the vehicle driven by fuel charging within a preset time period based on the total mileage, total power consumption and charging power; determining the fuel consumption within a preset time period based on the third mileage and the fuel consumption of the hybrid electric vehicle within a preset time period; and estimating the fuel endurance based on the determined fuel consumption.

[0091] For example, it is assumed that in the pure electric driving mode (i.e., the battery-only driving mode), the hybrid electric vehicle travels a total of 20 kilometers within 10 minutes, wherein the power consumption is 20% of the total battery power per 100 kilometers.

[0092] The total power consumption within 10 minutes = 20 km / (100 km / 20%) = 4% of the total battery power.

[0093] Assume that the battery charge changes from 6% to 3% within 10 minutes.

[0094] The battery charge capacity within 10 minutes = 4% - 3% of the total battery capacity = 1% of the total battery capacity.

[0095] The mileage of a car driven by fuel charging within 10 minutes = 20 kilometers * 1% / 4% = 5 kilometers.

[0096] The fuel consumption is 0.5 liters within 10 minutes.

[0097] Fuel consumption within 10 minutes = 5 km / 0.5 liter = 10 (kilometers per liter), that is, the fuel consumption is 10 liters per 100 kilometers.

[0098] Then, the fuel range is estimated based on the determined fuel consumption of "10 liters per 100 kilometers" and the remaining fuel amount.

[0099] 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.

[0100] In some possible implementations of the embodiments of the present application, estimating the fuel range based on the determined fuel consumption may include: determining a comprehensive fuel consumption for estimating the fuel range based on the determined fuel consumption and historical fuel consumption; and estimating the fuel range based on the comprehensive fuel consumption.

[0101] In some possible implementations of the embodiments of the present application, when determining the comprehensive fuel consumption for estimating the fuel range based on the determined fuel consumption and the historical fuel consumption, the determined fuel consumption and the historical fuel consumption can be averaged and the average value can be used as the comprehensive fuel consumption.

[0102] For example, assuming that within one hour in history, the fuel consumption determined every 10 minutes is 9.9 liters per 100 kilometers, 10.1 liters per 100 kilometers, 10 liters per 100 kilometers, 9.8 liters per 100 kilometers, 10 liters per 100 kilometers, and 10.2 liters per 100 kilometers respectively.

[0103] The comprehensive fuel consumption = (9.9 liters of fuel per 100 kilometers + 10.1 liters of fuel per 100 kilometers + 10 liters of fuel per 100 kilometers + 9.8 liters of fuel per 100 kilometers + 10 liters of fuel per 100 kilometers + 10.2 liters of fuel per 100 kilometers + 10 liters of fuel per 100 kilometers) / 7 = 10 liters of fuel per 100 kilometers.

[0104] The process of estimating fuel range in hybrid driving mode is as follows: Figure 2 As shown. Figure 2 In the process, first, the mileage contributed by electric energy is determined based on the total power consumption and power consumption of the hybrid electric vehicle. Then, the mileage contributed by fuel is determined based on the total mileage and the mileage contributed by electric energy. Then, the current fuel consumption is determined based on the mileage contributed by fuel and the fuel consumption. Then, the comprehensive fuel consumption is determined based on the current fuel consumption and historical fuel consumption. Finally, the fuel endurance is estimated based on the comprehensive fuel consumption and the remaining fuel.

[0105] The process of estimating fuel range in fuel-only driving mode is as follows: Figure 3As shown. Figure 3 In the process, first, the amount of fuel used for charging the battery is determined according to the change of battery power and the oil-to-electricity conversion rate, and then the fuel consumption for driving the car is determined according to the total fuel consumption and the amount of fuel used for charging the battery. Then, the current fuel consumption is determined according to the fuel consumption for driving the car and the car mileage. Then, the comprehensive fuel consumption is determined based on the current fuel consumption and historical fuel consumption, and then the fuel range is estimated based on the comprehensive fuel consumption and the remaining fuel.

[0106] The process of estimating fuel range in battery-only driving mode is as follows: Figure 4 As shown. Figure 4 In the process, the total power consumption is first determined according to the total mileage and power consumption, and then the charging power is determined according to the total power consumption and the change in battery power. Then, the mileage of the car driven by fuel charging is determined according to the total mileage, total power consumption and charging power. Then, the current fuel consumption is determined according to the mileage and fuel consumption of the car driven by fuel charging, and then the comprehensive fuel consumption is determined according to the current fuel consumption and historical fuel consumption. Finally, the fuel endurance is estimated based on the comprehensive fuel consumption and the remaining fuel.

[0107] In some possible implementations of the embodiments of the present application, the cruising range estimation method provided in the embodiments of the present application may further include:

[0108] Estimate the total driving range of the hybrid electric vehicle based on the fuel range and electric range.

[0109] In some possible implementations of the embodiments of the present application, the electric range can be estimated based on the power consumption and the current battery charge. Then, the fuel range and the electric range are added together to obtain the total range of the hybrid electric vehicle.

[0110] For example, the estimated fuel range is 480 kilometers. The power consumption is 20% of the total battery power per 100 kilometers. The current remaining battery power is 40% of the total battery power.

[0111] Electric energy range = 100 km / 20%*40% = 200 km.

[0112] Total cruising range = 480 km + 200 km = 680 km.

[0113] Corresponding to the above method embodiment, the present application embodiment also provides a cruising range estimation device, such as Figure 5 shown.

In this way, the fuel range can be estimated according to the fuel range estimation strategy corresponding to the obtained driving mode of the hybrid electric vehicle, which can improve the accuracy of the estimated fuel range.
