1. A vibration damping device for a vehicle, comprising:
a subframe to which a vibration of a wheel is transmitted;
a plurality of mounts arranged between the subframe and a vehicle body and configured such that stiffness of each mount in a prescribed direction changes according to an excitation current supplied thereto; and
a controller configured to control the excitation current supplied to each mount,
wherein the controller is configured to:
set a target elastic center of the subframe; and
individually calculate the excitation current supplied to each mount so as to match an actual elastic center of the subframe with the target elastic center.
