To provide a self-shutoff abnormality detection device capable of disconnecting a power source of a control device even in the case where an abnormality occurs on a self-shutoff function.
The control device for a vehicle is provided with a main power source voltage detection means for detecting a voltage value of a main power source; a self-shutoff control means for outputting a command for always stopping feeding of the power source to a power source control circuit after feeding of the power source is always received from the power source control circuit and the shutoff processing is executed when an ignition key is turned OFF and the detected voltage value of the main power source becomes a set value or lower previously set. The self-shutoff control means is provided with an abnormality judgment part for judging that the main power source voltage detection means is abnormal when the main power source voltage detection means does not detect the voltage value of the main power source; and a power source stopping instruction part for outputting the command for always stopping feeding of the power source to the power source control circuit when it is judged that the main power source voltage detection means is abnormal.
