The present invention relates to an electric device reset prevention control device of a vehicle. The present invention is to provide an electronic device reset prevention control device for a vehicle capable of preventing the reset of an electrical device and at the same time preventing deterioration in startability when the vehicle restarts an engine in an idle stop and go (ISG) mode. According to the present invention, the electronic device reset prevention control device for a vehicle comprises: a vehicle battery directly connected to a start motor for starting an engine; an auxiliary battery connected to a drive video record system (DVRS); a switching unit disposed between an output terminal of the vehicle battery and an output terminal of the auxiliary battery to electrically connect any one of the vehicle battery and the auxiliary battery to a vehicle electric device; and a DVRS controller for connecting the switching unit to an auxiliary battery when cranking is required to restart the engine after the vehicle enters and stops in ISG mode, to convert the power of the electric device from the vehicle battery to the auxiliary battery.
