Abstract
Provided is a vehicular control device that is provided with a switching circuit, and for opening/closing a connection between a starter including a capacitor that is to be connected to one end portion of the switching circuit and an in-vehicle battery that is to be connected to another end portion of the switching circuit by controlling an on/off state of the switching circuit. The control device includes a voltage detection unit configured to detect a voltage of the one end portion, and a control unit configured to control the switching circuit to turn off from on, and determine whether there is a failure in the switching circuit, based on a voltage detected by the voltage detection unit when a predetermined time has elapsed from when the switching circuit is controlled to turn off from on.
