Abstract:
1. A hybrid vehicle control device which controls a hybrid vehicle comprising an internal combustion engine, a power generator which generates electric power by mechanical power of the internal combustion engine, a first inverter which controls the power generator, a motor which drives a wheel, and a second inverter which controls the motor, the hybrid vehicle control device comprising: a detecting unit which detects, during driving of the first inverter, a value which is defined in advance and which is necessary for a failure/non-failure diagnosis of at least one of the power generator and the first inverter, and a control unit which controls the driving of the first inverter and which diagnoses failure/non-failure of at least one of the power generator and the first inverter based on a detection result by the detecting unit, wherein the control unit stops driving of the first inverter when the control unit judges that the failure/non-failure diagnosis is not necessary during electric running in which the wheel is driven with the motor, and the control unit instructs to drive the first inverter until the detection by the detecting unit is completed even during the electric running when the control unit judges that the failure/non-failure diagnosis is necessary.
