To suppress deterioration of traveling performance of a vehicle and suppress deterioration of drivability.SOLUTION: A vehicular motor control device controls first and second inverters so as to drive first and second motors by a torque command individually set to the first and second motors. Whether resonance is generated in at least one of first and second driving systems on the basis of the number of rotation of the first and second motors is determined. When resonance is generated in at least one of the first and second driving systems, the torque command of the motor included in the resonating driving system of the first and second driving systems is limited by a predetermined torque limit.SELECTED DRAWING: Figure 3

    【課題】車両の走破性の低下を抑制すると共に、ドライバビリティの低下を抑制する。【解決手段】第1、第2モータに対して個別に設定されるトルク指令で第1、第2モータが駆動するように第1、第2インバータを制御する車両用のモータ制御装置であって、第1、第2モータの回転数に基づいて第1、第2駆動系の少なくとも一方に共振が発生しているか否かを判定し、第1、第2駆動系の少なくとも一方に共振が発生しているときには、第1、第2駆動系のうち共振している駆動系に含まれるモータのトルク指令を予め定めたトルク制限で制限する。【選択図】図3
