Abstract

A vehicle control device using a semiconductor fuse, and enabling an increase in size of the semiconductor fuse to be suppressed and the occurrence of an abnormal current to be detected early to enable shut off of the abnormal current. The vehicle control device includes 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; and a temperature detector that detects the temperature of the shut-off unit. Furthermore, the vehicle control device includes 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 the load devices for which the priority is low, based on priorities set for each of the plurality of load devices.
