The present invention relates to an active short circuit control apparatus of an electric motor driving system and a method thereof, which comprises: a driving motor which is connected to a vehicle shaft to provide driving force; a driving motor system which controls the driving motor by using the active short circuit, and operates the active short circuit depending on the safety state request of the driving motor system; and an active short circuit current stabilizer which selectively generates a freewheeling comparison value to stabilize the driving motor system by using the current information and speed information of the driving motor depending on whether the active short circuit is in a transient state when the active short circuit is operated before outputting the same to the driving motor system. Therefore, the size of the peak phase current is reduced, and vibration time is shortened, thereby suppressing an overcurrent and a vibration current.
