Abstract
A power transmission device is disclosed. The power transmission device includes an input member, an output member, a dynamic vibration absorbing device, a rotation fluctuation detecting unit, and a control unit. The input member is rotatably disposed and configured to receive the torque inputted from a drive source. The output member is configured to output the torque, inputted to the input member, to a drive wheel. The dynamic vibration absorbing device is disposed in a power transmission path including the input member and the output member. The rotation fluctuation detecting unit is configured to detect information regarding a rotational fluctuation in at least one of the input member and the output member. The control unit is programmed to perform active control of the dynamic vibration absorbing device so as to reduce the rotational fluctuation based on the information regarding the rotational fluctuation detected by the rotational fluctuation detecting unit.
