Abstract: A drive motor control system performs control of a drive motor of a vehicle that includes the drive motor and a battery. The drive motor control system includes a control processor that controls an electric current supply from the battery to the drive motor and includes an operational state determiner that determines whether a condition that the vehicle is being stopped, a condition that a parking brake is being released, and a condition that a parking range is being selected are satisfied. When the operational state determiner determines that all the conditions are satisfied upon a reception of a trigger signal instructing a start of the control of the drive motor, the control processor performs control of an inverter such that the electric current supply is performed to cause the drive motor to repeat small revers rotations and thereby induce small movements of the vehicle in front and rear directions.
