Provided is a vibration suppression control device for a vehicle system, the device using motor speed information to suppress vibration due to resonance, and thereby improve vehicle riding comfort. The present invention is provided with a feedback control configuration in which: included is an approximation model in which a transmission characteristics model for torque input to a vehicle and a motor rotational speed is approximated to a transfer function that is the product of an integral term for a motor moment of inertia and a quadratic expression of filter characteristics; the approximation model is used to differentiate a speed detection component ωm of the motor rotational speed to determine a motor acceleration torque component TmA; the motor acceleration torque component TmA is passed through a band-pass filter Fcomp(s) to obtain a compensation torque component TFcomp which is then subtracted from an input torque command Tref.
