Gear shifting speed regulation control system and control method for speed change device

The invention provides a gear shifting speed regulation control system and control method for a speed change device, and the system comprises a speed change controller which is connected with a motor controller, obtains corresponding parameters and preset conditions, and transmits the corresponding parameters and preset conditions to the motor controller connected with the speed change controller; the motor controller correspondingly controls a speed regulation motor connected with the motor controller to be regulated from the current rotating speed to the target rotating speed according to the received speed regulation instruction; a rotating speed sensor on the gearbox is not used, so that the problems of slow low-speed response, low rotating speed precision, easy interference of signal interaction and the like in the existing scheme are solved; three control units are simplified into two control units, so that the interaction time is shortened, and the fault occurrence probability is reduced. 本发明提供一种用于变速装置
