The present invention relates to a vehicular control device and to a fail-safe method. The control device includes: a circuit that monitors an operation of a processor 11a in a main control unit 11; and a circuit that monitors a supply voltage Vcc of processor 11a. When processor 11a is in a normal operation state but the supply voltage Vcc abnormally increases, a part of control functions that operative sub-control units 12, 13, 14, 15, . . . , fulfill are shut off in accordance with a control command from main control unit 11. This makes it possible to maintain the control function to the extent possible even when the supply voltage Vcc of processor 11a abnormally increases while processor 11a operates normally.
