CONTROL DEVICE FOR VEHICLE

In a vehicle including a charge circuit for carrying out external charging to charge a vehicle-mounted battery with a power supply external to the vehicle, a vehicle ECU (300) includes a first termination instruction unit (320). A charger ECU (400) includes an instruction execution unit (410) and a current reduction control unit (420). The first termination instruction unit (320) determines that there is an impedance error when a state where a reduction width of an input voltage Vin applied to the charge circuit from the power supply external to the vehicle is exceeding a threshold width V continues for a predetermined time, and outputs a first termination instruction to the instruction execution unit (410). The instruction execution unit (410) receiving the first termination instruction causes the charge circuit to stop to terminate external charging. The current reduction control unit (420) controls the charge circuit such that, when the input voltage Vin falls down to a threshold voltage V1 higher than an operation lower limit value Vmin by just a predetermined value, the current flowing through an external power supply system is reduced to suppress further reduction in the input voltage Vin.
