Range extender control method and device, computer readable storage medium and vehicle

Abstract

The embodiment of the invention discloses a range extender control method and device, a computer readable storage medium and a vehicle. The range extender control method comprises the following stepsof counting daily trip characteristic data; calculating predicted power consumption data and allowable power generation data of a range extender according to the daily trip characteristic data; controlling running of the range extender according to initial remaining electric quantity, the predicted power consumption data and the allowable power generation data. According to the range extender control method and device, the computer readable storage medium and the vehicle, the driving habits and daily driving conditions of a driver can be analyzed by counting the daily trip characteristic dataof the vehicle and inputting the data to an electric quantity consumption prediction model, and the power consumption condition is predicted on the basis of the driving habits and the daily driving conditions. Because the power generation capacity of the range extender is related to the speed of the vehicle, the allowable power generation condition of the range extender can be predicted, and the range extender is controlled to be started at appropriate time in combination with the acquired initial remaining electric quantity, so that an operation control strategy and related control parametersof the range extender are more reasonably optimized.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular, to a range extender control method, a range extender control device, a computer-readable storage medium and a vehicle. Background technique [0002] In the environment of energy conservation and emission reduction, REEV (Range Extended Electric Vehicle, range-extended electric vehicle) has become an important technical direction, which is equipped with Electric Vehicle, plug-in hybrid electric vehicle) with a larger capacity battery can fully cover the needs of short-distance travel in urban areas. At the same time, the range extender is involved in the work during long-distance travel, which can extend the driving mileage. [0003] While realizing energy saving and emission reduction, REEV also eliminates the driver's mileage anxiety. Determined by the technical characteristics of this type of vehicle, its range extender operation control strategy has a huge impact on v...
