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.
