Problems solved by technology

[0003] During the shifting process of the vehicle, the clutch of the current gear is disengaged and the clutch of the new gear is engaged, and the oil pressure demand of the system increases. At this time, the oil pressure of the system cannot be adjusted on the basis of the original switch valve technology, resulting in the maximum clutch oil pressure. When the load is large, the pressing force cannot meet the load requirements, and the clutch appears slippery
When the oil pressure in the system is too high, it will cause the deformation of the spring or the high degree of adhesion between the clutch friction plate and the steel plate, and even damage the parts.

Abstract

The invention discloses a vehicle gear shifting control method and device, electronic equipment and a storage medium, and belongs to the technical field of automobiles. Clutch oil pre-charging state information is obtained; an oil pressure compensation coefficient is obtained based on the gear state information in the vehicle gear shifting process and the clutch oil pre-charging state information; and oil pressure compensation is conducted on the gear shifting process based on the oil pressure compensation coefficient. The current pressure fluctuation is calculated according to the current engine rotating speed and the switching process, and then the power-up current of the electromagnetic valve is adjusted according to the corresponding relation between the duty ratio of the electromagnetic valve and the pressure until the pressure is stabilized at the required pressure point. The clutch system is combined and compressed according to a set calculated pressure point, sufficient power is transmitted to the whole vehicle, and the probability of damage to internal components of the clutch is reduced.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a vehicle shift control method, device, electronic device and storage medium. Background technique [0002] my country is a big country in automobiles. With the rapid development of the automobile industry, the related technologies related to automobiles are becoming more and more mature. [0003] During the shifting process of the vehicle, the current gear clutch is disengaged, the new gear clutch is engaged, and the demand for system oil pressure increases. At this time, the system oil pressure cannot be adjusted on the basis of the original switch valve technology, resulting in the maximum pressure of the clutch. When the load is large, the pressing force cannot meet the load requirements, and the clutch slips. When the system oil pressure is too large, it will cause the spring deformation or the high adhesion of the clutch friction plate and the steel plate, and ...
