  "textContent": "A control system for a movable body configured to move by utilizing a motor torque generated by a drive motor, is provided. The system includes the drive motor including a rotor configured to output a rotational force and provided with a variable-magnetic-force magnet, and a stator opposing the rotor with a gap therebetween and provided with a plurality of coils, a powertrain component provided so as to be associated with the drive motor, and a controller having a magnetization controlling module configured to control magnetizing current flowing through the coils so as to change a magnetic force of the variable-magnetic-force magnet. During a demagnetization control in which the magnetic force of the variable-magnetic-force magnet is reduced by the magnetization controlling module, the controller operates the powertrain component to suppress a decrease in a moving force applied to the movable body due to a decrease in the motor torque.",
