1. A vehicle control device comprising:
a shut-off unit that supplies and shuts off a supply of power to a plurality of load devices;
a current detector that detects a current flowing to the plurality of load devices;
a temperature detector that detects a temperature of the shut-off unit; and
a drive controller that, when the temperature of the shut-off unit detected by the temperature detector exceeds a predetermined value, controls and restricts operation of any of the plurality of load devices for which a priority is low, based on priorities set for each of the plurality of load devices, and
wherein, when the temperature of the shut-off unit exceeds the predetermined value, the drive controller provides a time difference between startup timings of the plurality of load devices, based on a decreasing value of a drive current upon starting each of the plurality of load devices, and the priorities thereof.
