[0029] 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.

[0030] 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.

[0031] 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:

[0032] S110: Obtaining the remaining fuel amount of the hybrid electric vehicle and the road condition information of the route to be traveled by the hybrid electric vehicle.

[0033] The remaining fuel of the hybrid electric vehicle at the current moment and the road condition information of the hybrid electric vehicle's route to be driven are obtained. The vehicle's route to be driven is a route from the vehicle's current position to the destination, which can be a route from the vehicle's position to the destination when the vehicle is traveling based on a pre-planned driving route.

[0034] S120: Estimate the operating condition of the engine of the hybrid electric vehicle based on the road condition information.

[0035] The operating condition of the engine of the hybrid electric vehicle is estimated based on the road condition information, such as the torque and speed of the engine. Specifically, the energy consumption of the hybrid electric vehicle during driving is estimated according to the energy management strategy of the hybrid electric vehicle, and then the operating condition data of the engine is determined.

[0036] S130: Estimate a first fuel consumption of the hybrid electric vehicle based on the operating condition of the engine.

[0037] The fuel consumption of the hybrid electric vehicle for engine charging is estimated based on the estimated engine operating conditions.

[0038] S140: Calculate a second fuel consumption of the hybrid electric vehicle based on the first fuel consumption of the hybrid electric vehicle and a historical fuel consumption of the hybrid electric vehicle.

[0039] Specifically, an average value may be calculated based on the first fuel consumption of the hybrid electric vehicle and the historical fuel consumption of the hybrid electric vehicle as the second fuel consumption of the hybrid electric vehicle.

[0040] S150: Calculate a fuel cruising range based on a second fuel consumption of the hybrid electric vehicle and a remaining fuel amount of the hybrid electric vehicle.

[0041] The fuel cruising range of the hybrid electric vehicle is calculated by dividing the second fuel consumption of the hybrid electric vehicle by the remaining fuel volume of the hybrid electric vehicle.

[0042] The method for determining the fuel range provided in the embodiment of the present application can estimate the operating condition of the engine based on the acquired road condition information of the route to be traveled by the hybrid electric vehicle, further estimate the first fuel consumption of the vehicle, and determine the current second fuel consumption of the vehicle in combination with the historical fuel consumption of the hybrid electric vehicle, and use the second fuel consumption and the remaining fuel amount of the vehicle to calculate the fuel range of the vehicle, thereby improving the accuracy of the calculation of the fuel range of the vehicle.

[0043] In some embodiments, before calculating the second fuel consumption of the hybrid electric vehicle based on the first fuel consumption of the hybrid electric vehicle and the historical fuel consumption of the hybrid electric vehicle, the method includes: determining a first driving mileage contributed by electric energy in the preset time period according to the total power consumption and power consumption of the hybrid electric vehicle in the preset time period; determining a second driving mileage contributed by fuel in the preset time period according to the first driving mileage and the total driving mileage of the hybrid electric vehicle in the preset time period; determining the historical fuel consumption in the preset time period according to the second driving mileage and the fuel consumption of the hybrid electric vehicle in the preset time period. In the case where the driving mode is the hybrid driving mode, determining the first driving mileage contributed by electric energy in the preset time period according to the total power consumption and power consumption of the hybrid electric vehicle in the preset time period; determining the second driving mileage contributed by fuel in the preset time period according to the first driving mileage and the total driving mileage of the hybrid electric vehicle in the preset time period; determining the fuel consumption in the preset time period according to the second driving mileage and the fuel consumption of the hybrid electric vehicle in the preset time period.

[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] In some embodiments, determining the historical fuel consumption within the preset time period based on the second driving mileage and the fuel consumption of the hybrid electric vehicle within the preset time period includes: determining the historical fuel consumption for estimating the fuel cruising range based on the fuel consumption and the fuel consumption of the target time period, where the target time period is the time period before the preset time period. Performing weighted calculation on the fuel consumption and the fuel consumption of the target time period to obtain the historical fuel consumption for estimating the fuel cruising range. The fuel consumption of the target time period may be an average value of the fuel consumption in multiple segments within the target time period.

[0049] In some embodiments, calculating the second fuel consumption of the hybrid electric vehicle based on the first fuel consumption of the hybrid electric vehicle and the historical fuel consumption of the hybrid electric vehicle includes: weighted calculation of the second fuel consumption of the hybrid electric vehicle based on the first fuel consumption of the hybrid electric vehicle and the historical fuel consumption of the hybrid electric vehicle. When weighted calculation is performed based on the first fuel consumption of the hybrid electric vehicle and the historical fuel consumption of the hybrid electric vehicle, the weights of the first fuel consumption and the historical fuel consumption can be adjusted. For example, the second fuel consumption = 0.5 × the first fuel consumption + 0.5 × the historical fuel consumption.

[0050] In some embodiments, obtaining the road condition information of the route to be traveled by the hybrid electric vehicle includes: obtaining the road condition information of the route from the current position of the hybrid electric vehicle to the target position through map navigation. Obtaining the real-time road condition information of the route from the current position of the hybrid electric vehicle to the target position through map navigation. The map navigation of the hybrid electric vehicle is implemented by map navigation software.

[0051] In some embodiments, the road condition information includes at least one of road slope, vehicle speed, traffic flow information, length of different road sections, and road type. The road type may be an expressway, main road, secondary road, and branch road based on the urban road grade classification, or may be obtained based on other road classification methods.

[0052] In one embodiment, hybrid electric vehicles include two types: extended-range and plug-in. When the type of road the vehicle is traveling on is a mountain road, strong power needs to be provided. For extended-range vehicles, the range extender is turned on to continuously charge the vehicle; for plug-in vehicles, the hybrid driving mode is enabled. Among them, when the extended-range vehicle enables the engine for charging, all the fuel is used for charging and not for driving the vehicle, so the estimated fuel consumption is 0. When the type of road the vehicle is traveling on is a flat road, low power needs to be provided. For extended-range vehicles, the engine is turned off; for plug-in vehicles, it is a pure electric driving mode.

[0053] In one example, the fuel consumption of a hybrid electric vehicle is as follows: Figure 2 As shown, the total mileage of the car is 300 kilometers. When the car is traveling on rural roads from 0 to 40 kilometers, the fuel consumption is 4.2 liters per 100 kilometers. When the car is traveling on mountain roads from 40 to 125 kilometers, the fuel consumption increases to 8.1 liters per 100 kilometers. When the car is traveling on urban roads from 125 to 225 kilometers, the fuel consumption decreases to 1.2 liters per 100 kilometers.

[0054] The method for determining the fuel range provided in the embodiment of the present application can estimate the engine operating condition based on the road condition information of the hybrid electric vehicle's route to be traveled obtained through map navigation, and further estimate the vehicle's first fuel consumption. The vehicle's current second fuel consumption can be determined based on a weighted calculation of the first fuel consumption and historical fuel consumption, and the vehicle's fuel range is calculated based on the second fuel consumption, thereby improving the accuracy of the vehicle's fuel range calculation.
