A motor driving control method for controlling a motor speed so that a speed measured value of a motor follows a speed command value is provided. The method includes driving the motor by repeating an on section where a torque is generated in the motor and an off section where a torque is not generated in the motor at a regular period, based on the speed command value, wherein the driving includes applying a phase voltage to only one of multiple phases of the motor in the on section by a pulse width modulation scheme.

A method for managing discharged water discharged from a moving object includes: receiving a setting request indicating whether or not to store the discharged water that is discharged due to electricity generation of a fuel cell; receiving, as a response to storing the discharged water, a utilization mode for using the discharged water as utilization water for specific use; setting a target water temperature of the utilization water based on the received utilization mode being set; adjusting the water temperature of the utilization water based on the target water temperature through heat exchange between a component constituting the moving object and the utilization water; and providing the utilization water according to the received utilization mode.
