Abstract

An electric movable body includes an output shaft and multiple motors that drive the output shaft. The electric movable body performs a double drive control to assign a drive state to at least two of the motors, performs, when the double drive control is performed and on determination that one of the motors is abnormal, a single drive control to assign the drive state to only one of the motors and to assign a stop state to another of the motors, and identifies, when the single drive control is performed, a drive motor, to which the drive state is assigned and which is abnormal, based on a predetermined state quantity correlated with a drive state of the drive motor.
