Problems solved by technology

However, under certain working conditions, such as turning on the air conditioner, plateau environment, and slamming on the brakes, the engine speed will drop to a certain speed in advance, causing the engine to resume fuel supply in advance, which is not conducive to reducing the fuel consumption of the vehicle

Abstract

The present disclosure relates to a method and device for controlling fuel cutoff and shifting of a vehicle, electronic equipment and a storage medium. The method for controlling fuel cutoff and shifting of a vehicle includes detecting the fuel supply state of the vehicle engine; if it is judged that the vehicle engine is in the state of fuel cutoff, detecting Whether the set conditions are met; among them, the vehicle meets the set conditions including the vehicle's air conditioner is turned on, the vehicle is driving in a plateau environment, or the vehicle brakes suddenly; if it is judged that the vehicle meets the set conditions, the fuel cut-off compensation speed of the engine is obtained; among them, the fuel cut-off compensation The rotational speed is greater than the corresponding engine oil supply recovery rotational speed under the set conditions; the downshift node of the vehicle is controlled according to the fuel cut-off compensation rotational speed. Through the technical solution of the present disclosure, the corresponding engine speed is corrected in real time when the vehicle downshifts, so as to realize the engine running above the engine's refueling speed, and avoid the vehicle under special working conditions such as turning on the air conditioner, plateau environment, and sudden braking. Resupply the oil supply in advance after the oil is cut off, thus saving the fuel consumption of the vehicle.

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...
