<P>PROBLEM TO BE SOLVED: To provide a transmission test device for preventing the speed of a dynamometer for driving from pulsating as a whole device. <P>SOLUTION: The transmission test device includes dynamometers 3 and 4 for driving and absorption, and a speed detection section is provided at a side of the dynamometer 3 for driving, and a torque detection section is provided at a side of the dynamometer 4 for absorption. The control section of the dynamometers 3 and 4 consists of a speed feedback command section 8a, a toque feedback command section 8b and a torque compensation section 13. The speed feedback command section 8a controls the speed of the dynamometer 3 for driving, and the torque feedback command section 8b controls the load of the dynamometer 4 for absorption. The torque compensation section 13 obtains a compensation torque command value from a speed deviation generated in the dynamometer 3 for driving, and applies the compensation torque command value to the dynamometer 4 for absorption. <P>COPYRIGHT: (C)2013,JPO&INPIT |
