a motor output decision unit configured to decide a magnitude of an output of the motor, based on a magnitude of a requested output that is an output requested to be supplied to the drive wheels;
a first rotation number decision unit configured to decide a first target value of a rotation number of the motor, based on the magnitude of the output of the motor decided by the motor output decision unit; and
a display control unit configured to change a display method of the power indicator in a case where the motor supplies power to the drive wheels in a first mode and in a case where the motor supplies power to the drive wheels in a second mode different from the first mode, wherein
the motor supplies power to the drive wheels in the second mode when the output of the motor decided by the motor output decision unit is equal to or larger than a predetermined first threshold value and the first target value of the rotation number decided by the first rotation number decision unit is equal to or larger than a predetermined second threshold value.

2. The control device according to claim 1 , further comprising:
a display value decision unit configured to decide a display value indicative of the magnitude of power that is displayed on the power indicator, wherein
the display value decision unit is configured to decide the display value, based on the rotation number of the motor decided by the first rotation number decision unit.

3. The control device according to claim 2 , wherein
the first mode is an operation mode in which the rotation number of the motor is adjusted so that an efficiency of the motor when the motor outputs power is equal to or larger than a predetermined value or is larger than the predetermined value, and
the second mode is an operation mode in which the rotation number and torque of the motor are adjusted so that the moving body changes speed in a pseudo stepped shifting manner.
