<P>PROBLEM TO BE SOLVED: To suppress the vibration of a drivetrain caused by to the torque fluctuation of an internal combustion engine in a vehicle. <P>SOLUTION: This damping device of a vehicle is provided with feedforward control unit 110 for calculating damping torque outputted by a motor generator 300 for suppressing the vibration of a drivetrain from the estimated value of torque outputted from an engine 100 by using the inverse function of the transfer function of a single-freedom vibration model which is equivalent to a multi-freedom vibration model in one natural vibration mode of the plurality of natural vibration modes owned by the multi-freedom vibration model when the drivetrain including an engine 200, the motor generator 300 and a drive shaft 11 or the like is simulated with the multi-freedom vibration model. <P>COPYRIGHT: (C)2010,JPO&INPIT |
