Abstract:
A backup device for a vehicle performs backup of a plurality of drive sources based on power supply from a second power supply unit even when power supply from a first power supply unit stops and reduces the peak voltage necessary in the backup operation. In a backup device, when an abnormal state of the power supply from a first power supply unit is detected, a control unit instructs a discharge unit to intermittently apply a discharge current a plurality of times to each of a plurality of motors and controls a supply destination of the discharge current such that each instruction time period during which the discharge unit is instructed to apply the discharge current to one motor is shifted with respect to each instruction time period during which the discharge unit is instructed to apply the discharge current to the other motor.
