The embodiment of the invention discloses a gear shifting control method and device and a gearbox controller, and the method comprises the steps that the gearbox controller determines a to-be-switched target gear and determines a target rotating speed interval; under the condition that a gearbox controller judges that gear shifting is needed, the following steps are executed: a torque unloading instruction is sent to a motor controller, and the torque unloading instruction is used for instructing the motor controller to control a driving motor to unload torque to zero; the gearbox is controlled to be disengaged from the current gear to a neutral gear; sending a speed regulation instruction to the motor controller, wherein the speed regulation instruction is used for instructing the motor controller to control a driving motor to regulate the rotating speed to the target rotating speed interval; the gearbox is controlled to enter the target gear from the neutral gear; and sending a torque recovery instruction to a motor controller, wherein the torque recovery instruction is used for instructing the motor controller to control the driving motor to recover the torque to the target torque.

    本申请实施例公开了一种换挡控制方法及装置、变速箱控制器,该方法包括:变速箱控制器确定待切换的目标挡位,并确定目标转速区间;变速箱控制器判定需要换挡的情况下,执行以下步骤:向电机控制器发送卸扭指令,所述卸扭指令用于指示所述电机控制器控制驱动电机卸载扭矩至零;控制变速箱从当前挡位脱出至空挡;向所述电机控制器发送调速指令,所述调速指令用于指示所述电机控制器控制驱动电机调节转速至所述目标转速区间;控制变速箱从空挡进入所述目标挡位;向电机控制器发送扭矩恢复指令,所述扭矩恢复指令用于指示所述电机控制器控制驱动电机恢复扭矩至目标扭矩。
