PROBLEM TO BE SOLVED: To avoid occurrence of free vibration of a torsional damper by adjusting a torque variation period of an electric motor in a case where when a hybrid vehicle is in operation, if an internal combustion engine ceases running, torsion of the torsional damper is released, the free vibration of the torsional damper is excited accordingly, and vibration and/or noise of the vehicle thus occurs.SOLUTION: A vehicle 10 is a hybrid vehicle including a first electric motor 21, second electric motor 22, internal combustion engine 23, tortional damper 36, and control unit 61. When torsion of the torsional damper 36 is released, the control unit 61 decides in consideration of a quantity of elastic strain energy, which is stored in the torsional damper 36 at that time, whether a torque of the first electric motor 21 can be varied. |
