Abstract
A vehicle control device includes a power converter that converts supplied direct current power and supplies the converted direct current power to a load device. A first voltage detector detects a first voltage that is a voltage of the power supply line. A second voltage detector detects a second voltage that is a voltage of the power converter on a side where a power supply source is provided. When a first contactor is closed and brought into a state allowing current to flow through the first contactor, if a decreasing amount of the first voltage from a first time ago to a present time is greater than or equal to a first threshold and a decreasing amount of the second voltage from a second time ago to the present time is greater than or equal to a second threshold, a contactor controller opens the first contactor.
