Abstract: An apparatus and a method for controlling a power-train, and a storage medium storing a program for implementing the method are provided to decrease an output torque variation of an automatic transmission by using a stoppage unit for stopping a step-down of torque capacity of a frictional element. An automatic transmission down-shifts from a first gear stage to a second gear stage by releasing frictional hanging-tailored elements(C1,C2,C3,C4,B1) being in the hanging-tailored state. A driving source is connected to the automatic transmission and increases an output torque during the automatic transmission down-shifts. A control unit controls the frictional hanging-tailored elements to begin an inertia phase by stepping-down torque capacity of the frictional hanging-tailored elements when the automatic transmission down-shifts. A stoppage unit stops the step-down of the torque capacity of the frictional hanging-tailored elements when one of a revolution speed variation and a variable speed variation of a revolution member of the automatic transmission reaches up a predetermined value.
