Remaining mileage prediction method and system, computer equipment and readable storage medium

Abstract

The invention provides a remaining mileage prediction method and system, computer equipment and a readable storage medium, and the remaining mileage prediction method comprises the steps: obtaining a future driving route between a current position and a final position; segmenting a future driving route, and obtaining road condition information and temperature change information of the future driving route; calculating a driving habit score according to the operation of a driver on an accelerator and a brake pedal in historical unit time; predicting total energy consumption and unit mileage energy consumption of the future driving route according to the driving habit score, the road condition information of the future driving route and the air temperature change information; according to the total energy consumption and the energy consumption per unit mileage, calculating the remaining mileage of the vehicle when reaching the final position. According to the method and the device, the calculated and estimated remaining mileage is small in error and high in accuracy, the problem that the vehicle breaks down on the half road due to misjudgment of the user for future travel planning can be avoided, and the mileage anxiety of the user during long-distance travel is reduced.

Description

technical field [0001] The present invention relates to the field of electric vehicles, and in particular, to a method, system, computer equipment and readable storage medium for remaining mileage prediction. Background technique [0002] According to the national EV863-standard regulations, the driving mileage of an electric vehicle refers to the mileage that the electric vehicle travels from the fully charged state of the power battery to the end of the test specified in the standard, and the remaining mileage refers to the current situation of the vehicle in the current situation. The mileage that can be driven with the driving style and the accuracy of the remaining mileage calculation is one of the most concerned issues for electric vehicles, which directly leads to the user's mileage anxiety. [0003] Most of the existing electric vehicle remaining mileage estimation methods are calculated based on historical power consumption and available battery power, or converted ...

AI Technical Summary

Problems solved by technology

[0004] Based on this, the purpose of the present invention is to provide a remaining mileage prediction method, system, computer equipment and readable storage medium, to solve the problem that road conditions and ambient temperature cannot be comprehensively considered in the method for estimating remaining mileage in the prior art. Factors such as driving habits and driving habits lead to a large error in the calculated mileage, which causes users to misjudge future travel plans and cause the vehicle to break down halfway.
