PROBLEM TO BE SOLVED: To provide a suspension device in which torque fluctuation such as motor cogging is suppressed.SOLUTION: The suspension device of a vehicle includes a wiring H connecting current-carrying terminals of a motor 40, an electric circuit 100 having a coil 102 and a variable capacitor 103 both serially inserted in the wiring H, a target frequency setting means for setting a pulsation frequency of cogging torque for a target frequency of a resonance frequency of the electric circuit 100, a target capacitance determining means for determining target capacitance CI* which is a target value of capacitance of the variable capacitor 103 so that the resonance frequency of the electric circuit 100 can become equal to the target frequency, and a capacitance adjusting means for adjusting the capacitance of the variable capacitor 103 based on the target capacitance CI* determined by the target capacitance determining means. |
