The invention discloses a gear shifting process control method, a controller, a system and a pure electric vehicle, and the method comprises the following steps: in a neutral gear stage, obtaining a rotating speed control mode sent by an automatic speed change control device; based on the rotating speed control mode, obtaining a target motor rotating speed; based on the target motor rotating speed, controlling the driving motor to enter a strong speed regulation stage; in an emphasized speed regulation stage, iteratively controlling the driving motor to regulate the speed by using the first calibrated rotating speed and the first limiting torque; if the rotating speed difference between the actual motor rotating speed and the target motor rotating speed under the strong speed regulation reaches the set rotating speed difference, the driving motor is controlled to enter a weak speed regulation stage; and in the weak speed regulation stage, the second calibration rotating speed and the second limiting torque are used for replacing the first calibration rotating speed and the first limiting torque correspondingly, and the driving motor is continuously and iteratively controlled for speed regulation till gear engaging is completed.

    本发明公开了一种换挡过程控制方法、控制器、系统及纯电动汽车,方法包括:在空挡阶段,获取自动变速控制装置发送的转速控制模式;基于转速控制模式,获取目标电机转速;基于目标电机转速,控制驱动电机进入强调速阶段;在强调速阶段,利用第一标定转速和第一限制扭矩迭代控制驱动电机进行调速;若强调速下的实际电机转速和目标电机转速之间的转速差达到设定转速差,控制驱动电机进入弱调速阶段;在弱调速阶段,利用第二标定转速和第二限制扭矩分别替代第一标定转速和第一限制扭矩,并持续迭代控制驱动电机进行调速,直至挂挡完成为止。
