The invention discloses a control method for improving driveability of a full electric vehicle and belongs to the field of automobile controlling. The method includes the following steps that driving wheel speed and motor rotating speed are obtained; the obtained driving wheel speed and the obtained motor rotating speed are calculated by combination with speed ratio of a main reducer of the electric vehicle so that revision torque is obtained; the obtained revision torque is overlaid to a torque request signal of a whole vehicle controller for a motor to serve as a new torque request signal so as to control the motor. According to the control method for improving driveability of the full electric vehicle, the obtained driving wheel speed and the obtained motor rotating speed are calculated by combination with the speed ratio of the main reducer of the electric vehicle to obtain the revision torque, the obtained revision torque is overlaid with an original torque request signal of the whole vehicle controller to form the new torque request signal so as to control the motor, motor output acceleration curve is quite smooth while a large value is maintained, thereby, fast acceleration of the full electric vehicle can be guaranteed and vehicle vibration can be effectively inhibited, the control method is simple and easy to implement, and driving comforts of the full electric vehicle are effectively improved.
