Abstract

The invention discloses a driving range processing method and device as well as a vehicle. The method comprises the steps of calculating a driving range calculation value of the vehicle at a current moment according to current remaining battery capacity and average power consumption of the vehicle; determining a correction coefficient corresponding to the remaining battery capacity; and based on the correction coefficient and a driving range correction strategy, correcting the driving range calculation value to obtain a driving range display value of the vehicle at the current moment, whereinthe driving range display value is the corrected driving range calculation value, the driving range correction strategy is related to the correction coefficient, and the difference between the drivingrange display value of the vehicle at the current moment and the driving range display value of the vehicle at a previous moment is within a preset range. The driving range processing method can ensure that the driving range display value obtained after correction changes slowly, thereby eliminating the range anxiety and doubts of a user, and canensure that the driving range displayed by the vehicle has higher reliability.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method, device and vehicle for processing driving range. Background technique [0002] At present, the vehicle mainly displays the mileage through the combination instrument or the central control panel. The mileage refers to the expected driving mileage of the vehicle under the current vehicle state through calculation, which can be used to guide the owner to charge before the power is exhausted. Or indirectly tell the owner whether the vehicle can reach the desired destination. [0003] In the prior art, the mileage value is mainly calculated by dividing the remaining battery power sent by the battery management system (Battery Management System, BMS) by the current power consumption per kilometer of the vehicle. The large fluctuations in electricity consumption per kilometer lead to large fluctuations in the calculated value of the driving range. If the calculated value...
