The invention discloses an electric drive system low-temperature gear engaging control method, device and equipment and a medium. The method comprises the following steps: in a low-temperature state, identifying different power driving states of the electric driving system; outputting different motor request rotating speeds according to different power driving states; in the gear engaging synchronous control period, the motor is controlled to enter a motor rotating speed control mode based on the motor request rotating speed till the motor rotating speed control mode is controlled to exit according to the real-time shifting fork position and the target shifting fork position; and controlling the motor to enter a motor zero-torque control mode. According to the scheme, gear engaging control under the low-temperature condition is optimized, and the problem that the gear engaging success rate of the motor is low under the low-temperature condition is solved.

    本发明公开了一种电驱系统低温挂挡控制方法、装置、设备及介质。该方法包括:在低温状态下,识别电驱系统不同的动力驱动状态;根据不同的所述动力驱动状态输出不同的电机请求转速;在挂挡同步控制时期,基于所述电机请求转速控制电机进入电机转速控制模式直至根据实时拨叉位置与目标拨叉位置控制所述电机转速控制模式退出;控制电机进入电机零扭矩控制模式。本方案针对低温情况下的挂挡控制进行优化,避免了低温情况下电机挂挡成功率低的问题。
