Vehicle driving range calculation self-adapting method and device and vehicle

Abstract

The invention discloses a vehicle driving range calculation self-adapting method and device and a vehicle. The method comprises the steps that all variables related to the driving range of the to-be-measured vehicle in a preset variable set are determined; a unit energy consumption model of the to-be-measured vehicle is determined according to the first type of variables in all the variables, and a battery capacity model of the to-be-measured vehicle is determined according to the second type of variables in all the variables; the unit energy consumption of the to-be-measured vehicle is determined according to the unit energy consumption model, and the available capacity of a battery of the to-be-measured vehicle is determined according to the battery capacity model; and the driving range of the to-be-measured vehicle is determined according to the available capacity and the unit energy consumption of the to-be-measured vehicle. According to the vehicle driving range calculation self-adapting method and device and the vehicle, the corresponding unit energy consumption and battery available capacity are determined uniquely according to all the variables related to the driving range of the to-be-measured vehicle, the driving range of the to-be-measured vehicle is determined according to the unit energy consumption and the battery available capacity, the calculation accuracy of the driving range is guaranteed, the error is lowered, and the working efficiency can be improved easily.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to an adaptive method and device for calculating the mileage of a vehicle and a vehicle. Background technique [0002] At present, the mileage of new energy vehicles is mainly calculated based on battery power and unit energy consumption. As for the vehicle controller, its development is based on modularization and platformization. The vehicle controller is suitable for more than a dozen or even dozens of models. Among them, the mode positioning of different models is different, for example: some only have normal mode, some have normal mode, economy mode, sports mode and so on at the same time. The configuration of the same model is also different. For example, the batteries and motors assembled by the same model may be different; the type of batteries corresponding to the same battery supplier may also be different; The discharge matrix table may also be different. In t...
