Diagnostic apparatus and diagnostic method of hybrid vehicle

摘要

A diagnostic apparatus of a hybrid vehicle includes an internal combustion engine, an electricity storage device, a motor generating a driving force for a vehicle travel using at least electricity from the electricity storage device, a diagnostic unit diagnosing a vehicle state when an output of the internal combustion engine is zero, a state detection unit detecting a state of the electricity storage device, a remaining time acquisition unit acquiring a remaining time required until diagnostic completion, when the vehicle state is diagnosed by the diagnostic unit, a determination unit determining whether or not the diagnosis of the vehicle state is continued by the diagnostic unit, based on the state of the electricity storage device and the remaining time when the vehicle state is diagnosed by the diagnostic unit, and a control unit that controls continuation or stop of the vehicle state diagnosis according to the determination result.

主权项

1. A diagnostic apparatus of hybrid vehicle comprising:
an internal combustion engine; an electricity storage device; a motor that generates a driving force for vehicle travel using at least an electricity storage power of the electricity storage device; a diagnostic unit that diagnoses a vehicle state in a state where an output of the internal combustion engine is zero; a state detection unit that detects a state of the electricity storage device; a remaining time acquisition unit that acquires a remaining time required until a diagnostic completion, when the vehicle state is diagnosed by the diagnostic unit; a determination unit that determines whether or not the diagnosis of the vehicle state is continued by the diagnostic unit, when the vehicle state is diagnosed by the diagnostic unit, based on the state of the electricity storage device detected by the state detection unit and the remaining time acquired by the remaining time acquisition unit; and a control unit that controls continuation or stop of the vehicle state diagnosis according to a determination result of the determination unit.
