Abstract
When an anomaly is determined in the transition of ECUs to a power saving state, a power supply control system sequentially turns on current supply switches while keeping a bypass switch on. A monitoring controller determines an anomaly in the transition of the ECUs to a power saving state on the basis of whether the dark current in the ECUs calculated from the amount of change at that time in the current in the power supply line is greater than an ordinary dark current. Further, in the startup state of the ECUs, power from a power supply can be supplied to the ECUs via the power supply line and individual supply lines.
