Beschreibung
Zusammenfassung:	A diagnostic apparatus of a hybrid vehicle having an internal combustion engine, a motor, and a diagnostic unit that diagnoses a vehicle state by motoring the internal combustion engine using the motor in a zero output state. A detection unit detects a required driving force of a driver. A determination unit determines whether or not a remaining time required until a diagnostic completion is a predetermined time or less, in a case where the required driving force with a predetermined lower limit value or more is detected by the required driving force detection unit when the vehicle state is diagnosed by the diagnostic unit. A control device causes the motor to output the driving force, when the remaining time is the predetermined time or less, and continues the vehicle state diagnosis using the diagnostic unit by motoring the engine when the output of the internal combustion engine is zero.
