Abstract
A transmission testing device that can highly accurately reproduce behavior of an actual engine includes a drive dynamometer DMconnected to an input shaft of a transmission, absorption dynamometers DMand DMthat are connected to output shafts of the transmission, a shaft torque detection unit that detects a shaft torque value generated at the input shaft of the transmission, and a control unit that controls the drive dynamometer DM. The control unit uses the shaft torque value detected by the shaft torque detection unit to generate a shaft torque correction value for the drive dynamometer DM, receives an engine torque input value and uses the received engine torque input value to generate an engine torque correction value for the drive dynamometer DM, and controls the drive dynamometer DMon the basis of a torque command value generated from the shaft torque correction value and the engine torque correction value.
