1. An electric movable body comprising:
a plurality of output shafts;
a plurality of motors each configured to drive an output shaft of the output shafts;
a plurality of batteries, the motors and the batteries being connected to each other, such that each of the batteries is configured to supply electric power to a motor set each configured to drive one of the output shafts;
a first control unit configured to perform a first control to assign either a drive state or a stop state to each of the motors, such that the output shaft is driven by at least one of the motors, and such that each of the batteries supplies electric power to at least one of the motors;
an abnormality determination unit configured to determine an abnormality of the motors;
a switching unit configured to, when an abnormal motor determined by the abnormality determination unit is in the drive state, perform a switching control
to switch the abnormal motor into the stop state and
to switch an other one of the plurality of motors, which is in the stop state and configured to drive the same output shaft as the abnormal motor, into the drive state; and
a second control unit configured to, when the switching unit performs the switching control, perform a second control to assign either the drive state or the stop state to one of the motors, which constitutes the motor set including the abnormal motor, and to one of the motors, which constitutes the motor set including the other motor, such that each of the output shafts is driven by at least one of the motors, and such that each of the batteries supplies electric power to at least one of the motors.
