Problems solved by technology

[0004] However, since the mapping relationship table between the remaining power (or remaining fuel) and the remaining mileage is constructed by the vehicle manufacturer based on the test data of the vehicle to be shipped, the mapping relationship between the remaining power (or remaining fuel) and the remaining mileage is more suitable It is used to predict the remaining mileage of the vehicle just leaving the factory, so that when the remaining mileage of the vehicle (for example, a vehicle that has been used for many years) is predicted by using the mapping relationship table between the remaining power (or remaining fuel) and the remaining mileage, the remaining mileage of the forecast The mileage is usually inaccurate, and the predicted remaining mileage is usually higher than the actual remaining mileage, which makes users feel mileage anxiety because they cannot determine the actual remaining mileage based on the predicted remaining mileage, which seriously affects the user experience.

Embodiment 1

[0058] see figure 1 , which is a flow chart of the remaining mileage prediction method provided by the method embodiment of the present application.

[0059] The remaining mileage prediction method provided in the embodiment of the present application includes steps S11-S14:

[0060] S11: Obtain historical operating condition data of the target vehicle within the first time period.

[0061] S12: According to the historical working condition data, predict the predicted working condition data in the second time period in the future.

[0062] S13: Predict the energy consumption value per unit mileage of the future target vehicle according to the predicted working condition data.

[0063] S14: Predict the remaining mileage of the target vehicle according to the energy consumption value per unit mileage and the energy state data.

[0064] The above are the specific execution steps of the remaining mileage prediction method provided by the first embodiment of the method of the pr...

Embodiment approach

[0091] In addition, in order to improve the forecasting efficiency of the predicted working condition data, a large amount of historical working condition data in the first time period can be statistically analyzed, so that the working condition data prediction model only needs to make predictions based on a small number of statistical parameters. In this way, the present application also provides a second implementation of step S12. In this implementation, S12 may specifically include steps S121-S122:

[0092] S121: Perform statistical analysis on the historical working condition data, and obtain statistical parameters of the historical working condition data.

[0093] The present application does not limit the statistical analysis method, and may be any existing or future statistical analysis method capable of performing statistical analysis on historical working condition data.

[0094] Statistical parameters of historical working condition data refer to parameters that can...

Embodiment 3

[0130] S13B2: Obtain the predicted energy state data according to the statistical parameters of the predicted energy state data.

[0131] S13B3: Predict the energy consumption value per unit mileage of the future target vehicle according to the predicted driving mileage and predicted energy state data.

[0132] The specific implementation manner of step S13B3 is the same as the specific implementation manner of step S13A2, and for the sake of brevity, details are not repeated here.

[0133] The above is the specific implementation manner of step S13.

[0134] The specific implementation manner of step S14 is introduced below.

[0135] In step S14, since the energy state data can represent the energy state of the target vehicle at the current time, and the energy consumption value per unit mileage can represent the energy consumed by the target vehicle within the unit mileage after the current time, therefore, it can be Predict the remaining mileage of the target vehicle acco...

Abstract

The invention discloses a method and device for predicting the remaining range. Predicted work condition data in a future time period is predicted according to the historical work condition data of atarget vehicle in a first time period, and the energy consumption value of a future target vehicle within the unit range is predicted according to the predicted work condition data so that the remining range of the target vehicle can be predicted according to the energy consumption value within the unit range and energy state data in the historical work condition data. Due to the fact that the predicted work condition data can accurately show the work condition of the target vehicle in the future second time period and the energy consumption value within the unit range can accurately show theenergy consumption condition of the target vehicle in the future second time period, the remaining range predicted based on the energy consumption value within the unit range is more accurate, it is avoided that a user generates range anxiety due to the fact that the user cannot determines the actual range according to the predicted remaining range, and the experience feeling of the user is improved.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a remaining mileage prediction method and device. Background technique [0002] When driving a vehicle for travel, the user needs to pay attention to the parameters displayed on the dashboard in the car, especially the remaining mileage displayed on the dashboard. When the vehicle is a fuel vehicle, the remaining mileage refers to the mileage that the vehicle can travel continuously under the current remaining fuel; when the vehicle is an electric vehicle, the remaining mileage refers to the mileage that the vehicle can continuously travel under the current remaining power. [0003] In the prior art, the remaining mileage can usually be queried from the mapping relationship table between the remaining power (or remaining fuel) and the remaining mileage according to the current remaining power (or current remaining fuel), so as to predict the remaining mileage. [0004...
