The invention relates to a motor control device and a motor control method. An ECU (40) controls a motor (31) having a first coil group (52) and a second coil group (53). The ECU calculates a first torque command value and a second torque command value. The ECU corrects a second torque command value for the second coil group (52) on the basis of a first differential torque, which is the difference between the first theoretical output torque and the first predicted output torque. The ECU corrects a first torque command value for the first coil group (52) on the basis of a second differential torque, which is the difference between the second theoretical output torque and the second predicted output torque. The ECU controls the supply of power to the first coil group on the basis of the corrected first torque command value, and controls the supply of power to the second coil group on the basis of the corrected second torque command value.
本发明涉及电机控制装置以及电机控制方法。ECU(40)控制具有第一线圈组(52)以及第二线圈组(53)的电机(31)。ECU运算第一转矩指令值以及第二转矩指令值。ECU基于第一理论输出转矩与第一预测输出转矩的差亦即第一差分转矩对针对第二线圈组(52)的第二转矩指令值进行修正。ECU基于第二理论输出转矩与第二预测输出转矩的差亦即第二差分转矩对针对第一线圈组(52)的第一转矩指令值进行修正。ECU基于修正后的第一转矩指令值控制对第一线圈组的供电,基于修正后的第二转矩指令值控制对第二线圈组的供电。
