Abstract

The invention discloses a method, a device, equipment and a computer readable storage medium for estimating residual driving mileage. The method comprises the following steps: calculating a measured value of average power consumption of a purely electric vehicle within the first preset distance; judging the current working condition of the purely electric vehicle; if the current working conditionof the purely electric vehicle is driving running, optimizing the measured value of the average power consumption by utilizing Kalman filtering so as to obtain the optimal estimated value of the average power consumption within the first preset distance; and estimating the residual driving mileage of the purely electric vehicle by utilizing the optimal estimated value of the average power consumption and the residual electric quantity of the purely electric vehicle. The method, the device, the equipment and the computer storage medium provided by the invention can inhibit great fluctuation ofthe estimated value of the residual driving mileage. The invention also provides the purely electric vehicle which comprises the equipment used for estimating the residual driving mileage and capableof relatively quickly and accurately estimating the residual driving mileage.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to a method, device, equipment, computer-readable storage device and a pure electric vehicle for estimating the remaining mileage. Background technique [0002] Pure electric vehicles are vehicles powered by batteries. The development of electric vehicles can effectively save resources and reduce environmental pollution. During the driving process, the driver of the pure electric vehicle judges the driving ability of the pure electric vehicle according to the remaining mileage displayed on the instrument of the pure electric vehicle. Various factors such as the complex driving conditions of the pure electric vehicle, the changing driving environment, and the different driving habits of different drivers have a great impact on the accuracy of the estimation of the remaining driving range. If the estimated remaining mileage is too high, it may mislead the driver to j...
