Abstract

The invention discloses a driving range processing method, device and vehicle, wherein the method includes: calculating the current driving range calculation value of the vehicle according to the current battery remaining power and average power consumption of the vehicle; The correction coefficient corresponding to the remaining power; based on the correction coefficient and the driving range correction strategy, the driving range calculation value is corrected to obtain the driving range display value of the vehicle at the current moment; wherein, the driving range The displayed value is the corrected cruising mileage calculation value, the cruising mileage correction strategy is related to the correction coefficient, and the difference between the cruising mileage display value at the current moment of the vehicle and the cruising mileage display value at the previous moment is in advance. within the setting range. The driving mileage processing method provided by the present invention can ensure that the corrected driving range display value changes slowly, thereby eliminating the user's mileage anxiety and doubt, and ensuring that the driving range displayed by the vehicle has high reliability.

Description

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