Abstract

The application provides a method and device for reducing fuel consumption of a hybrid electric vehicle, electronic equipment and a storage medium. The method comprises the following steps of obtaining the average vehicle speed at the historical time, the vehicle speed at the current time, and the battery state of charge at the current time; obtaining the speed limit for starting the engine and stopping the engine according to the average speed at the historical time and the battery state of charge at the current moment; obtaining the battery state of charge limit set of starting engine and stopping engine according to the average speed of the historical time; determining the current engine state; achieving the start and stop controlling of a motor according to the speed limit of startingengine, the speed limit of stopping engine, the limit set of battery state of charge of starting engine and stopping engine, the vehicle speed at the current time, and the battery state of charge at the current time. This method can effectively reduce the fuel consumption of hybrid electric vehicle.

Description

technical field [0001] The present application relates to the technical field of hybrid vehicles, in particular to a method, device, electronic equipment and storage medium for reducing fuel consumption of hybrid vehicles. Background technique [0002] The hybrid vehicle has two power sources, the internal combustion engine and the electric motor. The start and stop of the engine are completely decoupled from the vehicle movement. The start and stop of the engine are determined by the start and stop control strategy in the controller. motor driven. The general operating conditions of hybrid electric vehicles are as follows. In urban conditions, the vehicle is driven at low speed, and the motor is used as much as possible to avoid inefficient operation of the engine; in high-speed conditions, the engine needs to be started to charge the battery, store energy, and optimize engine operation. operating conditions to maximize system efficiency. Hybrid vehicles currently on the ...
