Abstract
A vehicle control device includes: a current detecting unit for detecting a current flowing through a lead wire, and outputting a current detection value; a current interrupting unit for interrupting the current flowing through the lead wire; and a computing unit for computing a temperature rise value caused by Joule heat in the lead wire using the current detection value, estimating an environmental temperature of an environment in which the lead wire is wired based on the temperature rise value, outside air temperature information of a vehicle, inside air temperature information in a vehicle cabin, and solar radiation information, and determining whether to output a current interruption instruction to the current interrupting unit based on the temperature of the lead wire estimated using the environmental temperature.
