Document Type and Number:
Japanese Patent JP2020171067
Kind Code:
A
Abstract:
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
