The invention relates to electromechanical coupling control equipment for a pure electric vehicle power transmission system. The electromechanical coupling control equipment comprises a motor control device, a transmission system and a current parameter adjusting device, wherein the motor control device is used for outputting a motor torque, a motor rotor corner and motor current according to a target torque; the transmission system is connected with the motor control device and is used for obtaining a motor rotating speed according to the motor torque and transmitting the motor rotating speed to the motor control device for a feedback control on the motor torque; and the current parameter adjusting device is connected with the motor control device and is used for generating adjusting current according to the motor torque, the motor rotor corner and the motor current and transmitting the adjusting current to the motor control device for a feedback adjustment on the motor torque. Compared with the prior art, the feedback control is respectively carried out on the motor control device by the transmission system and the current parameter adjusting device through the motor rotating speed and the adjusting current; the control is finally carried out on vehicle power in an electromechanical coupling manner; the adjustment can be carried out on the motor torque; and the control on the speed of a vehicle is relatively accurate.
