A drive controlling device is provided to change the angle of a propeller shaft by power train or vibration of a vehicle body in order to reduce vibration noise caused by exciting force. A drive controlling device comprises: a first propeller shaft(10) to connect a transmission(1) to a center bearing(3); a measuring unit(100) to measure the angle of a second propeller shaft(20) connecting the center bearing to a rear axle(2); a driving unit(200) to generate current according to the angle measurement information in order to move the first propeller shaft up and down; and a controller(300) to operate the driving unit to move the first propeller shaft up and down. The measuring units are located in the transmission and the rear axle respectively. The controller minimizes the angle between the first propeller shaft and the second propeller shaft.
