A motor control device is provided in a vehicle equipped with a plurality of motors connected to a battery. The motor control device includes processors corresponding to the motors respectively. Each of the processors derives first power, derives second power, transmits information indicating the second power to another processor, acquires information indicating the second power derived by the another processor, derives third power, acquires fourth power, acquires a power limit value of the battery, derives a control power limit value, distributes the control power limit value to the motor corresponding to the own processor based on an axle torque ratio of the plurality of motors, derives an individual power limit value of the battery for the motor, derives a power correction amount of the first power, corrects the torque instruction value of the motor corresponding to the own processor, and operates the motor according to the corrected torque instruction value.
