Vehicle driving motor control method and system based on rotating speed control mode

The invention discloses a vehicle driving motor control method and system based on a rotating speed control mode, and belongs to the technical field of mechanical control, and the method comprises the steps: dividing an expected working condition of a driver according to an expected rotating speed instruction corresponding to the opening degree of an accelerator pedal; receiving a rotating speed instruction of the vehicle control unit and the real rotating speed of the motor; performing parameter calibration on the PI regulator by taking a driving motor controller to execute a full rotating speed range as a target; the maximum acceleration under each rotating speed condition in the full rotating speed range is calibrated by combining the wind resistance of the whole vehicle, the external characteristics of the motor and the dynamic property of the whole vehicle; converting the curve corresponding to the maximum acceleration into a limiting curve of a rotating speed instruction; calculating instruction adjusti
