Automatic gearbox gear shifting method, device and equipment and storage medium

Abstract

The invention provides an automatic gearbox gear shifting method, device and equipment and a storage medium. The method comprises the steps that the target air pressure of the environment where a target vehicle is located is obtained, if the target air pressure is lower than the preset air pressure, a preset automatic gearbox gear shifting point is corrected through a correction value of an automatic gearbox gear shifting point, and the target vehicle is subjected to gear shifting by using the corrected automatic gearbox gear shifting point. As the correction value of the automatic gearbox gear shifting point is the difference between the automatic gearbox gear shifting point under the pre-calculated target air pressure and the preset automatic gearbox gear shifting point, the correction value can well represent the change of the automatic gearbox gear shifting point under the target air pressure as compared with the preset automatic gearbox gear shifting point. According to the automatic gearbox gear shifting method, the situation that when the target vehicle is subjected to gear shifting through the corrected automatic gearbox gear shifting point, the performance of the whole vehicle is not reduced, and the automatic gearbox gear shifting method with environmental adaptability is achieved.

Description

technical field [0001] The present application relates to the technical field of vehicles, and in particular to an automatic transmission shifting method, device, equipment and storage medium. Background technique [0002] With the continuous development of science and technology, automatic transmission vehicles are more and more widely used in daily life. Automatic transmission vehicles are equipped with an automatic transmission, which can automatically change gears while the vehicle is moving, without manual operation. [0003] At present, automatic transmissions usually shift gears automatically according to pre-calibrated shift points. However, this shift point can only match the performance of the engine in the flat environment, that is, in the normal air pressure range. In the plateau environment, due to the low air pressure, low oxygen content, and less air intake of the engine, its performance will change greatly. Therefore, the existing automatic transmission shi...

However, this shift point can only match the performance of the engine in the flat environment, that is, in the normal air pressure range

In the plateau environment, due to the low air pressure, low oxygen content, and less air intake of the engine, its performance will change greatly. Therefore, the existing automatic transmission shifting method cannot match the changed engine performance well. resulting in reduced vehicle performance
