Abstract
An ECU controls a motor including a first coil group and a second coil group. The ECU calculates a first torque command value and a second torque command value. The ECU uses a first differential torque, which is the difference between a first theoretical output torque and a first predictive output torque, to correct the second torque command value for the second coil group. The ECU uses a second differential torque, which is the difference between a second theoretical output torque and a second predictive output torque, to correct the first torque command value for the first coil group. The ECU uses a corrected first torque command value to control power feeding to the first coil group and uses a corrected second torque command value to control power feeding to the second coil group.
