The regenerative braking controlling system includes an armature current sampling module, a calculating module, and an adjusting module. The calculating module includes a power calculating unit, an optimum phase angle calculating unit, an optimum regenerative current calculating unit, and a sub-optimum regenerative current calculating unit. The armature current sampling module samples current of the three phase armature windings. The power calculating unit determines a relationship between a regenerative power and a phase angle of the armature currents. The optimum phase angle calculating unit calculates an optimum phase angle, and obtain a phase regenerative path based on the optimum phase angle. The optimum regenerative current calculating unit calculates an optimum regenerative current limit point. The sub-optimum regenerative current calculating unit calculates a sub-optimum regenerative current limit point. The adjusting module adjusts regenerative current according to the optimum regenerative current limit point and the sub-optimum regenerative current limit point.
