Description

Technical Field

[0001] This disclosure relates to the field of calculating vehicle mileage, and more specifically, to a method, apparatus, storage medium, and electronic device for determining vehicle range. Background Technology

[0002] With the increasing number of new energy vehicles, determining their driving range has become a crucial issue. Existing driving range algorithms employ a phased approach, using different SOC (state of charge) values. When the SOC is high, the calculation method uses the SOC as a ratio, outputting the calculated real-time driving range proportionally to the nominal range. In the later stages when the SOC is low, the actual distance is calculated based on real-time energy consumption.

[0003] Because current technologies use algorithms that only decrease and never increase the displayed range for calculating vehicle range, if high energy consumption in the previous cycle causes the mileage to decrease too quickly, while low energy consumption in the current cycle increases the actual mileage, the instrument panel displays the mileage from the previous cycle, while the actual mileage is calculated in the background. When the actual mileage equals the mileage displayed on the instrument panel, the remaining range continues to change based on real-time energy consumption. This calculation method results in significant fluctuations in energy consumption per 100 kilometers, and the calculated mileage also fluctuates accordingly. Because the display strategy only decreases and never increases, there is a plateau in the displayed mileage, meaning the vehicle has actually traveled a certain distance, but the displayed range remains unchanged, making it impossible to show the vehicle's actual mileage.

[0028] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0036] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0037] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0038] First, the application scenario of this disclosure is explained. This disclosure is applied to the scenario of determining the driving range of a vehicle. In existing methods for determining the driving range, the calculation and display of the driving range mainly have the following problems:

[0039] The calculation of energy consumption uses the energy consumption per ten kilometers as an approximation for the energy consumption per hundred kilometers. If the energy consumption in the current calculation period is too high, while the energy consumption in the next calculation period is too low, the driving range calculated based on the average energy consumption will fluctuate significantly. Because the algorithm for calculating the vehicle's driving range adopts a strategy of only decreasing and not increasing the displayed range, if the energy consumption in the previous period was high, causing the driving range to decrease too quickly, and the energy consumption in the current period is low, increasing the actual driving range, the output instrument will display the driving range of the previous period. At this time, the output range will plateau for a period of time, causing the problem that the vehicle has actually traveled a certain distance but the displayed mileage remains unchanged.

[0040] To address the aforementioned problems, this application provides a method, apparatus, storage medium, and electronic device for determining a vehicle's driving range. The method involves periodically acquiring the vehicle's cumulative mileage, speed, output power, and remaining battery power. If the cumulative mileage exceeds a preset mileage threshold, a first energy consumption for a first preset mileage is determined based on the speed and output power acquired at the current moment, the speed and output power acquired at the previous adjacent moment, and the interval between the current moment and the previous adjacent moment. If the first preset mileage is less than or equal to the preset mileage threshold, a second energy consumption for the first preset mileage is determined based on the expected value and standard deviation of the first energy consumption. Finally, the vehicle's driving range is determined based on the remaining battery power and the second energy consumption. This filtering of the vehicle's real-time energy consumption improves the accuracy of vehicle energy consumption calculation, facilitating a more accurate determination of the vehicle's actual driving range.

[0041] The present disclosure will now be described in conjunction with specific embodiments.

[0042] Figure 1 This application illustrates a method for determining vehicle range according to an exemplary embodiment, such as... Figure 1 As shown, the method includes:

[0043] S101. Obtain the vehicle's cumulative mileage, speed, output power, and remaining battery power.

[0044] Here, the vehicle's cumulative mileage represents the total mileage traveled up to the current moment, and the output power represents the product of the voltage and current of the vehicle during operation.

[0045] S102. When the cumulative mileage exceeds the preset mileage threshold, the energy consumption distribution ratio of the first energy consumption of the vehicle at the first preset mileage is determined based on the current driving speed and output power, the driving speed and output power at the previous adjacent moment, and the interval between the current moment and the previous adjacent moment.

[0046] The first preset mileage can be the mileage that the vehicle has traveled most recently at the current moment. Therefore, the first preset mileage is less than or equal to the preset mileage threshold.

[0047] In one possible implementation, the first preset mileage can be divided into multiple second preset mileages. The energy consumption distribution ratio of the first energy consumption of the vehicle before the current moment can be determined by the distribution ratio of the energy consumption of each second preset mileage in the first energy consumption of the first preset mileage.

[0048] Wherein, the first preset mileage is less than or equal to the preset mileage threshold, and in order to improve the accuracy of predicting the vehicle's driving range, 100 kilometers can be used as the first preset mileage, and the driving range of the vehicle can be determined by updating the driving energy consumption of 100 kilometers in real time.

[0049] For example, based on the current speed, the speed at the previous adjacent time, and the interval between the current time and the previous adjacent time, the distance traveled by the vehicle within that interval can be determined. For instance, the average speed of the vehicle at the current time and the previous adjacent time can be used to perform a trapezoidal integral to calculate the distance traveled within that interval, as shown in the following formula:

[0050]

[0051] Among them, Range [i] spd represents the distance traveled by the vehicle during the i-th interval. i The speed of the vehicle at the current moment, spd i-1 dt represents the vehicle speed at the previous adjacent time, and dt represents the time interval.

[0052] Based on the current output power, the output power at the previous adjacent time, and the time interval, determine the vehicle's third energy consumption within that time interval. For example, use the power (average current × voltage) at the current and previous times to perform a trapezoidal integral to calculate the real-time power consumption. The calculation formula is as follows:

[0053]

[0054] Among them, Consume [i] The third energy consumption of the vehicle during the i-th interval, vi and v i-1 i represents the actual operating voltage of the vehicle at the current time and the previous adjacent time, respectively. i and i i-1 dt represents the actual operating current of the vehicle at the current time and the previous adjacent time, respectively, and dt represents the time interval.

[0055] If the cumulative mileage exceeds a preset mileage threshold, the energy consumption distribution ratio of the first energy consumption is determined based on the mileage within the interval and the third energy consumption within the interval.

[0056] Specifically, the fourth energy consumption of each second preset mileage within the first preset mileage can be determined based on the mileage traveled within the interval and the third energy consumption within the interval, wherein the second preset mileage is less than the first preset mileage; and the energy consumption distribution ratio of the first energy consumption can be determined based on the second preset mileage and the fourth energy consumption.

[0057] For example, the first preset mileage could be 100 kilometers, and the second preset mileage could be 1 kilometer. Using trapezoidal integrals, the energy consumption of the vehicle per kilometer within the first preset mileage is obtained based on the mileage traveled within the interval and the third energy consumption within the interval, thus obtaining the energy consumption distribution ratio of the vehicle within the first preset mileage, i.e., the energy consumption distribution ratio per kilometer within the 100 kilometers. Alternatively, the first energy consumption can be determined by accumulating the mileage traveled at multiple intervals to the first preset mileage, and then obtaining the sum of the third energy consumption at these multiple intervals; or, the first energy consumption can be determined by accumulating multiple second preset mileages to the first preset mileage, and then obtaining the sum of the fourth energy consumption corresponding to these multiple second preset mileages. Figure 2 As shown, the energy consumption distribution ratio of the first energy consumption is determined by the distribution ratio of the fourth energy consumption of all the second preset mileages within the first energy consumption of the first preset mileage, where μ represents the expected value of the distribution ratio and σ represents the standard deviation of the distribution ratio.

[0058] S103. Determine the second energy consumption of the first preset mileage based on the expected value and standard deviation of the energy consumption distribution ratio of the first energy consumption.

[0059] like Figure 2 As shown, since the energy consumption distribution ratio of the first energy consumption conforms to a normal distribution, in order to obtain the energy consumption of the first preset mileage more accurately, the first energy consumption can be filtered by the normal distribution probability of the normal distribution.

[0060] For example, based on the expected value and standard deviation of the energy consumption distribution ratio of the first energy consumption, the filtering coefficient is determined by the normal distribution probability calculation formula; the first energy consumption is filtered by the filtering coefficient and the preset normal distribution filtering formula to determine the second energy consumption.

[0061] For example, after determining the energy consumption distribution ratio of all the second preset mileages within the first preset mileage, the expected value and standard deviation of the energy consumption distribution ratio are calculated. Then, after determining the expected value and standard deviation of the first preset mileage, the normal distribution probability value of the energy consumption distribution ratio is calculated according to the third energy consumption and normal distribution probability calculation formula. Where f(x) represents the normal distribution probability, x represents the third energy consumption, μ represents the expected value of the distribution proportion, and σ represents the standard deviation of the distribution proportion. The normal distribution probability value is determined as the filtering coefficient, and the first energy consumption is filtered using a preset normal distribution filtering formula, as follows:

[0062] DynPC'(k)=(1-Δw(k))×DynPC(k-1)+Δw(k)×DynPC(k)

[0063] Wherein, DynPC'(k) represents the second energy consumption, Δw(k) represents the filter coefficient, DynPC(k-1) represents the first energy consumption of the previous adjacent time, and DynPC(k) represents the first energy consumption of the current time.

[0064] S104. Determine the vehicle's driving range based on the remaining battery power and the second energy consumption.

[0065] For example, the ratio of the remaining battery power to the second energy consumption can be obtained; the vehicle's range can be determined by multiplying the ratio by the first preset mileage.

[0066] Using the above method, the vehicle's cumulative mileage, speed, output power, and remaining battery power are periodically acquired. If the cumulative mileage exceeds a preset mileage threshold, a first energy consumption for a first preset mileage is determined based on the current speed and output power, the speed and output power acquired at the previous adjacent moment, and the interval between the current moment and the previous adjacent moment. If the first preset mileage is less than or equal to the preset mileage threshold, a second energy consumption for the first preset mileage is determined based on the expected value and standard deviation of the first energy consumption. Finally, the vehicle's driving range is determined based on the remaining battery power and the second energy consumption. This filtering of the vehicle's real-time energy consumption improves the accuracy of energy consumption calculation, facilitating a more accurate determination of the vehicle's actual driving range.

[0067] In another possible implementation, if the accumulated mileage is less than or equal to a preset mileage threshold but greater than a third preset mileage, the fifth energy consumption of the third preset mileage is determined based on the mileage and the third energy consumption within the interval; the vehicle's range is determined based on the third preset mileage, the fifth energy consumption, and the remaining battery power; if the accumulated mileage is less than or equal to the third preset mileage, the vehicle's range is determined based on the vehicle's nominal energy consumption per 100 kilometers and the remaining battery power.

[0068] For example, when a vehicle has just started driving, there is no historical data on its energy consumption. Therefore, the vehicle's range is determined directly based on its nominal energy consumption per 100 kilometers and remaining battery power. If the vehicle's mileage exceeds a third preset mileage, the range can be determined based on its actual energy consumption. To improve the accuracy of the estimated range, the preset mileage threshold can be minimized. For instance, if the first preset mileage is 100 kilometers, the threshold can also be set to 100 kilometers, and the third preset mileage can be set to 10 kilometers. If the vehicle's cumulative mileage is less than the preset mileage, the energy consumption per 10 kilometers can be used as the vehicle's current energy consumption, and the range can be determined based on this energy consumption per 10 kilometers and remaining battery power.

[0069] For example, you can first obtain the energy consumption of the vehicle's most recent 10-kilometer driving distance, and use that 10-kilometer energy consumption as the energy consumption for the vehicle's subsequent 10-kilometer driving distance. Then, based on the ratio of the remaining battery power to that 10-kilometer energy consumption, multiply it by 10 kilometers to obtain the vehicle's driving range.

[0070] Using the above method, the vehicle's range can be preliminarily estimated when the vehicle's mileage is relatively low, which helps users understand the vehicle's range capability.

[0071] Figure 3 This application illustrates another method for determining vehicle range according to an exemplary embodiment, such as... Figure 3 As shown, the method includes:

[0072] S301: Obtain the vehicle's cumulative mileage, speed, output power, and remaining battery power.

[0073] S302. Determine whether the vehicle's cumulative mileage exceeds a preset mileage threshold.

[0074] If the vehicle's cumulative mileage exceeds a preset mileage threshold, execute steps S303-S307.

[0075] If the vehicle's cumulative mileage is less than or equal to a preset mileage threshold, execute steps S308-S311.

[0076] S303. Obtain the distribution ratio of energy consumption per kilometer and the first energy consumption of the vehicle in the first preset mileage.

[0077] S304. Determine the expected value and standard deviation of the energy consumption distribution in the first preset mileage of the vehicle based on the distribution ratio.

[0078] S305. Determine the filter coefficients based on the expected value and standard deviation.

[0079] The filter coefficient can be calculated using the formula for normal distribution probability.

[0080] S306. Based on the filter coefficient and the first energy consumption, the energy consumption per 100 kilometers of the vehicle is determined by a preset normal distribution filter formula.

[0081] S307. Based on the energy consumption per 100 kilometers and the remaining battery power, determine the vehicle's driving range.

[0082] S308. Determine whether the vehicle's cumulative mileage is greater than the third preset mileage.

[0083] If the vehicle's cumulative mileage exceeds the third preset mileage, execute S309-S310.

[0084] If the vehicle's cumulative mileage is less than or equal to the third preset mileage, execute S311.

[0085] S309. Obtain the fifth energy consumption of the vehicle at the third preset mileage.

[0086] S310. Determine the vehicle's range based on the third preset mileage, the fifth energy consumption, and the remaining battery power.

[0087] S311. Determine the vehicle's driving range based on its nominal energy consumption per 100 kilometers and remaining battery power.

[0088] By adopting the above method, different range calculation methods are used at different stages of the vehicle's cumulative mileage, which improves the accuracy of vehicle energy consumption calculation and helps to more accurately determine the vehicle's actual range.
