| description | The invention provides a vehicle gear shifting control method, device and equipment and a storage medium, and relates to the technical field of vehicle control, and the method comprises the steps that operation parameters of a vehicle are obtained firstly, the operation parameters comprise the vehicle speed and the acceleration, and the road condition gradient is obtained through calculation; and establishing a vehicle kinetic equation, and calculating the load by using a recursive least square method. And calculating load resistance and gear shifting acceleration based on the gradient and the load, predicting vehicle speed loss and output shaft rotating speed loss, determining the target rotating speed of the output shaft, and further controlling gear change. According to the method, the speed regulation target is determined in advance by predicting the load and the gradient and estimating the vehicle speed and the rotating speed loss, the gear shifting success rate is increased, the vehicle driving performa |
