Abstract

The invention relates to a fuel cut-off gear shifting control method and device for a vehicle, electronic equipment and a storage medium. The fuel cut-off gear shifting control method for the vehiclecomprises the steps that the fuel supply state of an engine of the vehicle is detected; if the vehicle engine is judged to be in the fuel cut-off state, whether the vehicle meets set conditions is detected, wherein the vehicle meets the set conditions that an air conditioner of the vehicle is turned on, the vehicle runs in a plateau environment or the vehicle is braked suddenly; if it is judged that the vehicle meets the set conditions, the fuel cut-off compensation rotating speed of the engine is obtained, wherein the fuel cut-off compensation rotating speed is larger than the corresponding engine fuel supply recovery rotating speed under the set conditions; and a downshift node of the vehicle is controlled according to the fuel cut-off compensation rotating speed. By means of the technical scheme, the corresponding engine rotating speed during vehicle downshifting is corrected in real time, so that the engine operates above the oil supply recovery rotating speed of the engine, the situation that oil supply of the vehicle is recovered in advance after the vehicle is powered off under the special working conditions such as air conditioner starting, plateau environment and sudden brake stepping is avoided, and then vehicle oil consumption is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular to a method and device for controlling fuel cut and gear shifting of a vehicle, electronic equipment, and a storage medium. Background technique [0002] As the country's requirements for vehicle fuel consumption are getting higher and higher, and the punishment measures are becoming more and more severe, reducing vehicle fuel consumption has become an urgent task. Vehicle hardware measures to reduce fuel consumption include reducing driving resistance, optimizing engine combustion efficiency, and improving power transmission efficiency. For software control, there are also many strategies that can reduce fuel consumption. For example, engine-controlled deceleration and fuel cutoff is a good strategy. The basic principle is: when the vehicle is decelerating, the driver quickly releases the accelerator pedal, and the electronic control unit The control circuit of the f...
