PROBLEM TO BE SOLVED: To provide a vehicular control apparatus with improved probability of performing correct determination of a leakage region even under an adverse condition.SOLUTION: A vehicular control apparatus 30 includes: a leakage detector 42 for detecting deterioration in insulation resistance of an electric system; and a control device 30 for executing identifying control for identifying an insulation resistance deterioration region in response to an output of the leakage detector 42. The control device 30 causes a power control device such as an inverter 14 and a relay 40 to shift between a power shutoff state and no power shutoff state, the power control device being disposed in a power route from a battery B1 to a load and have power shutoff functionality, and identifies a spot where the deterioration in insulation resistance has occurred, on the basis of a magnitude of change in the output of the leakage detector 42 occurring before and after the state shift. |
