Problems solved by technology

[0003] However, compared with fuel vehicles, there is still a big gap in the convenience of pure electric vehicles, which is reflected in the distribution of charging piles is less than that of gas stations, so that users always have the anxiety of driving mileage
Different external factors, as well as the characteristics of large differences in the weight of commercial vehicles used in logistics, make the driving range fluctuate greatly
[0004] Estimating the driving mileage only by the rated power of the battery or the current remaining power will produce a large deviation, which may lead to the problem of running out of power during transportation or charging in advance to reduce the number of transportation

Abstract

The invention relates to the technical field of new energy vehicles, in particular to a method and device for determining the remaining mileage of a commercial vehicle. The method comprises the following steps: acquiring driving data of a vehicle in a preset sampling period; calculating an average vehicle speed according to the driving data; determining a basic electric energy consumption rate corresponding to the average vehicle speed based on a preset mapping relationship between the constant-speed vehicle speed and the electric energy consumption rate; calculating a correction factor influencing the power consumption rate based on the driving data; obtaining a corrected power consumption rate according to the basic power consumption rate and the correction factor; and determining the remaining mileage of the vehicle based on the battery remaining capacity, the average vehicle speed and the corrected electric energy consumption rate. According to the invention, the remaining mileageof the vehicle can be calculated more accurately.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a method and device for determining the remaining mileage of a commercial vehicle. Background technique [0002] Affected by environmental factors and driven by current policies and regulations, new energy vehicles have ushered in a period of rapid development, showing a trend of substantial growth. With the continuous breakthrough of battery technology and the gradual increase of battery energy density, the mileage of new energy vehicles, especially pure electric vehicles, has been able to meet the needs of users, and some pure electric vehicles have approached or reached the level of fuel vehicles. [0003] However, compared with fuel vehicles, there is still a big gap in the convenience of pure electric vehicles, which is reflected in the distribution of charging piles is less than that of gas stations, so that users always have the anxiety of driving mileage. Dif...
