Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a method, apparatus, device, and storage medium for determining vehicle driving range. Background Technology

[0002] Nowadays, hybrid electric vehicles are becoming increasingly common. However, when calculating the remaining fuel range for hybrid vehicles, the vehicle may charge the battery during driving, resulting in additional fuel consumption. This causes the fuel consumption used to calculate the range to be higher than the actual driving distance, making the calculated range reduction value greater than the actual driving distance. Consequently, the calculation of the remaining range is inaccurate, leading to a poor user experience.

[0016] When the vehicle travel distance is greater than or equal to the preset distance threshold, the recent average fuel consumption is determined based on the fuel consumption and the vehicle travel distance.

[0017] Optionally, after the step of obtaining the vehicle's driving mode in the current calculation period, the method further includes:

[0028] Optionally, the step of determining the recent average fuel consumption based on the power depletion fuel consumption and the vehicle's driving distance includes:

[0029] Obtain the pure electric driving distance of the vehicle during the current calculation period;

[0030] The fuel consumption driving distance is obtained by subtracting the pure electric driving distance from the vehicle's driving distance.

[0031] The recent average fuel consumption is determined based on the fuel-consuming driving distance and the fuel consumption during power supply.

Because the mileage calculation is not a simple proportional subtraction from the initial fuel level, but rather based on the vehicle's remaining fuel level and the current corrected fuel consumption, which is continuously adjusted as the vehicle travels, it more closely reflects the vehicle's actual fuel consumption, thus ensuring that the calculated driving range is closer to the vehicle's actual driving range.

The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0049] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the electronic device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0050] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a vehicle range determination program.

[0051] exist Figure 1 In the electronic device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the electronic device of the present invention can be set in the vehicle range determination device. The electronic device calls the vehicle range determination program stored in the memory 1005 through the processor 1001 and executes the vehicle range determination method provided in the embodiment of the present invention.

[0052] This invention provides a method for determining vehicle driving range, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of a method for determining vehicle driving range according to the present invention.

[0053] In this embodiment, the method for determining the vehicle's driving range includes the following steps:

[0054] Step S10: Obtain the vehicle's remaining fuel, vehicle speed, and previous corrected fuel consumption, and obtain the vehicle's recent average fuel consumption in the current calculation period.

[0055] It should be noted that the execution subject of this embodiment can be the vehicle range determination device or the vehicle itself. The vehicle range determination device can be a controller in the vehicle, such as an ECU controller, or other devices that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment and the following embodiments, the vehicle range determination device is used as an example to illustrate the vehicle range determination method of the present invention.

[0056] It should be noted that the vehicle range determination device will periodically adjust the vehicle's fuel consumption value using a preset duration as the calculation cycle. The preset duration can be set in advance by the administrator of the vehicle range determination device according to actual needs. For example, if the preset duration is set to 30 seconds, the vehicle range determination device will periodically calculate the vehicle's fuel consumption value using 30-second calculation cycles.

[0057] In practical use, if the current calculation cycle is the first calculation cycle, the previously corrected fuel consumption can use a fixed fuel consumption value. This fixed fuel consumption value can be the fuel consumption calibrated by the vehicle range determination equipment manager under standard operating conditions. Similarly, when calculating the initial range, i.e., when calculating the range for the first time, the initial range can be obtained by dividing the remaining fuel in the vehicle's fuel tank by the fixed fuel consumption value.

[0058] In its implementation, when the trigger condition for periodic calculation is met, the vehicle's remaining fuel level, vehicle speed, and previous adjusted fuel consumption are obtained by the vehicle's range determination device. The current calculation period can be a preset time range preceding the current trigger time. For example, if the current calculation trigger time is 9:00:30 and the preset duration is 30 seconds, then the corresponding time range for the current calculation period is 9:00:00-9:00:30. Remaining fuel level can be the current amount of fuel remaining in the vehicle's tank. Vehicle speed can be the instantaneous speed at the current moment or the average speed within the current calculation period. Previous adjusted fuel consumption can be the adjusted fuel consumption calculated in the previous calculation period. The vehicle's recent average fuel consumption within the current calculation period can be the average fuel consumption of the vehicle while driving within the current calculation period.

[0059] Step S20: Determine the fuel consumption correction coefficient based on the vehicle speed.

[0060] It should be noted that the fuel consumption correction factor is positively correlated with vehicle speed; that is, the higher the vehicle speed, the larger the fuel consumption correction factor, and the greater the correction force when correcting fuel consumption.

[0061] In practical use, determining the fuel consumption correction factor based on vehicle speed can be done by looking up the corresponding fuel consumption correction factor for the vehicle speed in a preset speed coefficient mapping table. This preset speed coefficient mapping table stores the mapping relationship between vehicle speed and fuel consumption correction factors, and this mapping relationship can be pre-set by the administrator of the vehicle range determination device.

[0062] Step S30: Determine the current corrected fuel consumption based on the fuel consumption correction coefficient, the previous corrected fuel consumption, and the recent average fuel consumption.

[0063] In practice, determining the current corrected fuel consumption based on the fuel consumption correction coefficient, the previous corrected fuel consumption, and the recent average fuel consumption can be done by calculating the current corrected fuel consumption based on the fuel consumption correction formula, the fuel consumption correction coefficient, the previous corrected fuel consumption, and the recent average fuel consumption.

[0064] The fuel consumption correction formula can be:

[0065] R AFC =R AFC-1 +(R 油 –RAFC-1 )*k

[0066] In the formula, R AFC The current corrected fuel consumption is given by k, where k is the fuel consumption correction factor, and R is the fuel consumption correction factor. AFC-1 For the previous adjustment of fuel consumption, R 油 This represents the recent average fuel consumption.

[0067] Step S40: Determine the vehicle's driving range based on the remaining fuel level and the current corrected fuel consumption.

[0068] In practice, determining the vehicle's driving range based on the remaining fuel and the current corrected fuel consumption can be achieved by dividing the remaining fuel by the current corrected fuel consumption.

[0069] This embodiment obtains the vehicle's remaining fuel level, vehicle speed, and previous corrected fuel consumption, and also obtains the vehicle's recent average fuel consumption in the current calculation period. A fuel consumption correction coefficient is determined based on the vehicle speed. The current corrected fuel consumption is determined based on the correction coefficient, the previous corrected fuel consumption, and the recent average fuel consumption. Finally, the vehicle's driving range is determined based on the remaining fuel level and the current corrected fuel consumption. Because the mileage calculation does not simply subtract the initial fuel level proportionally, but rather calculates the vehicle's driving range based on the remaining fuel level and the current corrected fuel consumption, and because the current corrected fuel consumption is continuously adjusted as the vehicle travels, it more closely reflects the vehicle's actual fuel consumption. This ensures that the calculated driving range is closer to the vehicle's actual driving range.

[0070] refer to Figure 3 , Figure 3 This is a flowchart illustrating a second embodiment of a method for determining vehicle driving range according to the present invention.

[0071] Based on the first embodiment described above, step S10 of the vehicle range determination method in this embodiment includes:

[0072] Step S101: Obtain the vehicle's remaining fuel, vehicle speed, and previous corrected fuel consumption.

[0073] It should be noted that driving modes can be categorized into pure electric mode, pure gasoline mode, and hybrid mode based on the power source during driving. To accurately calculate recent average fuel consumption, the vehicle's driving mode within the current calculation period can be obtained, and different methods can be used to calculate the recent average fuel consumption for different driving modes. Obtaining the vehicle's driving mode within the current calculation period can refer to obtaining the driving mode used by the vehicle within the time frame of the current calculation period. If the vehicle used both electric and gasoline drive during the current driving period, the driving mode can be determined as hybrid mode.

[0074] Step S102: If the vehicle's driving mode is pure oil mode, then obtain the vehicle's fuel consumption and driving distance in the current calculation cycle.

[0075] It should be noted that if the driving mode is pure gasoline mode, the vehicle will not consume fuel to charge the battery. Therefore, the recent average fuel consumption can be calculated directly based on fuel consumption and vehicle distance traveled. Fuel consumption can be obtained by statistically analyzing the amount of fuel injected by the engine during the current calculation period.

[0076] Step S103: Determine the recent average fuel consumption based on the fuel consumption and the vehicle travel distance.

[0077] It should be noted that determining the recent average fuel consumption based on fuel consumption and vehicle travel distance can be done by calculating the ratio of fuel consumption to vehicle travel distance and using this ratio as the recent average fuel consumption.

[0078] Furthermore, since calculating fuel consumption when the vehicle is idling or generating electricity in place would lead to excessively high fuel consumption, to avoid this phenomenon, step S103 in this embodiment may include:

[0079] The vehicle's travel distance is compared with a preset distance threshold;

[0080] When the vehicle travel distance is greater than or equal to the preset distance threshold, the recent average fuel consumption is determined based on the fuel consumption and the vehicle travel distance.

[0081] It should be noted that if the vehicle's travel distance is greater than or equal to the preset distance threshold, it means that the vehicle has traveled a relatively long distance in the current calculation period, and the vehicle is not idling or generating electricity while stationary. In this case, the recent average fuel consumption can be directly determined based on fuel consumption and vehicle travel distance. However, if the vehicle's travel distance is less than the preset distance threshold, it means that the vehicle has traveled a very short distance in the current calculation period, or even has not moved at all. In this case, the subsequent steps for calculating fuel consumption can be skipped.

[0082] The preset distance threshold can be set by the administrator of the vehicle range determination device according to actual needs, for example, the preset distance threshold can be set to 50m.

[0083] This embodiment obtains the vehicle's remaining fuel level, vehicle speed, and previous corrected fuel consumption, and acquires the vehicle's driving mode within the current calculation period. If the driving mode is pure fuel mode, it acquires the vehicle's fuel consumption and driving distance within the current calculation period. The recent average fuel consumption is determined based on the fuel consumption and driving distance. Since the electric motor does not participate in driving the vehicle in pure fuel mode, the recent average fuel consumption can be directly calculated from the vehicle's fuel consumption and driving distance within the current calculation period. The previous corrected fuel consumption is then further corrected based on the recent average fuel consumption to obtain a current corrected fuel consumption that more closely reflects actual fuel consumption.

[0084] refer to Figure 4 , Figure 4 This is a flowchart illustrating a third embodiment of a method for determining vehicle driving range according to the present invention.

[0085] Based on the second embodiment described above, after step S101 of the vehicle range determination method in this embodiment, the method further includes:

[0086] Step S102': If the vehicle's driving mode is hybrid mode, then obtain the vehicle's fuel consumption, electrical energy change, and driving distance during the current calculation period.

[0087] It should be noted that if the vehicle's driving mode is hybrid mode, the vehicle will consume fuel to charge the battery during driving. In order to accurately calculate the fuel range, it is necessary to eliminate the interference of fuel consumption during charging. In this case, the vehicle's fuel consumption, change in electrical energy, and driving distance during the current calculation period can be obtained.

[0088] Among them, the change in electrical energy can be the change in the state of charge (SOC) of the vehicle's battery during the current calculation cycle, which can be obtained by subtracting the SOC at the beginning of the current calculation cycle from the current SOC.

[0089] Step S103': Determine the power supply fuel consumption based on the fuel consumption and the change in electrical energy.

[0090] It should be noted that determining the power supply fuel consumption based on fuel consumption and changes in electricity consumption can be achieved by using the conversion coefficient between electricity and fuel to convert the changes in electricity into power generation fuel consumption, and then subtracting the power generation fuel consumption from the fuel consumption to obtain the power supply fuel consumption.

[0091] In actual operating conditions, the change in electrical energy may be positive or negative. When the change in electrical energy is positive, the converted fuel consumption for power generation is also positive, and the fuel consumption will be greater than the fuel consumption for power supply. When the change in electrical energy is negative, the converted fuel consumption for power generation is also negative, and the fuel consumption will be less than the fuel consumption for power supply. This process helps to offset any discrepancies and ensures that the final calculated recent average fuel consumption is closer to the actual fuel consumption during driving.

[0092] In a specific implementation, in order to accurately calculate the fuel consumption for power supply, step S103' in this embodiment may include:

[0093] Obtain the electric-to-fuel conversion coefficient of the vehicle in the current calculation cycle;

[0094] The power generation fuel consumption is determined based on the electro-oil conversion coefficient and the change in electrical energy.

[0095] The power supply fuel consumption is determined based on the fuel consumption and the power generation fuel consumption.

[0096] It should be noted that obtaining the vehicle's fuel-electric conversion coefficient within the current calculation period can be achieved by acquiring the vehicle's motion state (such as vehicle speed, vehicle acceleration, etc.) within the current calculation period, determining the power generation efficiency based on the motion state, and thus obtaining the fuel-electric conversion coefficient. Specifically, the fuel-electric conversion coefficient can be seen as a mapping relationship between fuel consumption and the increase in battery capacity when charging the vehicle battery. For example, if consuming 1L of fuel results in a 3.3kWh increase in battery capacity, then the fuel-electric conversion coefficient is 3.3L / kWh.

[0097] In practical applications, the fuel consumption for power generation can be determined by dividing the change in electrical energy by the fuel conversion coefficient. Similarly, the fuel consumption for power supply can be determined by subtracting the fuel consumption for power generation from the fuel consumption.

[0098] In practical implementation, the battery charging coefficient varies depending on the engine speed. Therefore, to ensure the accuracy of the calculated fuel consumption, the step of obtaining the battery charging coefficient for the current calculation period, as described in this embodiment, may include:

[0099] Obtain the average engine speed of the vehicle during the current calculation period;

[0100] The corresponding electric-to-oil conversion coefficient is found in the preset speed coefficient mapping table based on the average engine speed.

[0101] It should be noted that the average engine speed of the vehicle within the current calculation period can be the average engine speed of the vehicle within the current calculation period. The preset speed coefficient mapping table can store the mapping relationship between the electric-to-fuel conversion coefficient and the engine speed, and this mapping relationship can be pre-calibrated by the personnel in charge of the vehicle range determination equipment.

[0102] Step S104': Determine the recent average fuel consumption based on the power supply fuel consumption and the vehicle driving distance.

[0103] In practical use, the recent average fuel consumption can be determined by calculating the ratio of the fuel consumption to the vehicle's driving distance.

[0104] It should be noted that, in order to avoid the impact of idling and stationary power generation, before determining the recent average fuel consumption based on the fuel consumption of the depleted battery and the vehicle's driving distance, the vehicle's driving distance can be compared with a preset distance threshold to determine whether to calculate the recent average fuel consumption.

[0105] Furthermore, since the vehicle's engine does not start when the vehicle is driving in pure electric mode, including this data in the calculation would result in an underestimation of the current corrected fuel consumption. To overcome this deficiency, step S104' in this embodiment may include:

[0106] Obtain the pure electric driving distance of the vehicle during the current calculation period;

[0107] The fuel consumption driving distance is obtained by subtracting the pure electric driving distance from the vehicle's driving distance.

[0108] The recent average fuel consumption is determined based on the fuel-consuming driving distance and the fuel consumption during power supply.

[0109] It should be noted that the pure electric driving range can be the distance the vehicle travels using only the electric motor.

[0110] Understandably, subtracting the pure electric driving distance from the vehicle's total driving distance eliminates non-fuel-consuming driving scenarios, yielding the overall fuel-consuming driving distance. Then, by calculating the recent average fuel consumption based on this fuel-consuming driving distance and the amount of fuel consumed when the battery is depleted, a more accurate recent average fuel consumption can be obtained. This ensures that the final calculated corrected fuel consumption more closely reflects the vehicle's actual driving fuel consumption, thus guaranteeing the accuracy of the driving range calculation. Specifically, the vehicle's total driving distance is calculated by integrating the vehicle speed using wheel speed sensors; the pure electric driving distance is obtained separately by integrating the distance with the engine off.

[0111] This embodiment obtains the vehicle's fuel consumption, energy change, and driving distance within the current calculation period if the driving mode is hybrid mode; determines the battery depletion fuel consumption based on the fuel consumption and energy change; and determines the recent average fuel consumption based on the battery depletion fuel consumption and driving distance. Since the fuel consumption consumed to drive the vehicle (i.e., battery depletion fuel consumption) is calculated based on the vehicle's fuel consumption, energy change, and driving distance when the driving mode is hybrid mode, and the recent average fuel consumption is then determined based on the battery depletion fuel consumption and driving distance, this ensures that the obtained recent average fuel consumption is not affected by the fuel consumption for charging the battery, ensuring that the currently calculated corrected fuel consumption is closer to the vehicle's actual fuel consumption value.

[0112] Furthermore, this embodiment of the invention also proposes a storage medium storing a vehicle range determination program, wherein when the vehicle range determination program is executed by a processor, it implements the steps of the vehicle range determination method described above.

[0118] The determination module 40 is used to determine the vehicle's driving range based on the remaining fuel and the current corrected fuel consumption.

The current corrected fuel consumption is determined based on the correction coefficient, the previous corrected fuel consumption, and the recent average fuel consumption.
