Abstract:
1. A vehicular power control apparatus for performing power control of a hybrid vehicle using output of an internal combustion engine and output of an AC motor as sources of power, comprising: an internal combustion engine control unit to control the output of the internal combustion engine; an electric power converter that is connected to the AC motor and a DC power supply to form, together therewith, an electric power supply passage, performs power conversion by a switching operation of a switching unit, and supplies electric power from one of the DC power supply and the AC motor to the other; a hybrid control unit that has a function to control the output of the AC motor by controlling the switching operation of the electric power converter and cooperates with the internal combustion engine control unit to perform an arithmetical operation for the power control of the hybrid vehicle; a short-circuit abnormality detection unit that is provided in the hybrid control unit and detects an abnormality due to a short circuit fault of the electric power supply passage; and an internal combustion engine operation instruction unit that is provided in the hybrid control unit and gives, when the short-circuit abnormality detection unit detects the abnormality, an instruction, which causes the internal combustion engine to perform an operation corresponding to the abnormality, to the internal combustion engine control unit.
