Abstract
A driving force control device in which, based on the rotational speed of the motor mounted on the vehicle, it is determined whether resonance occurs in the vehicle with respect to the road, and when it is determined that resonance occurs in the vehicle, the torque of the motor is limited. Only the fluctuation component of the rotation speed is extracted from the rotation speed of the motor with a band-pass filter. When limiting the torque of the motor, the torque reduction is started at the timing of 270 degrees in the phase of the waveform which regards the extracted fluctuation component as the COS waveform.
