Abstract
In a hybrid vehicle, each of an engine and an MG1 is mechanically coupled to a drive wheel with a planetary gear being interposed. The planetary gear and an MG2 are configured such that motive power output from the planetary gear and motive power output from the MG2 are transmitted to the drive wheel as being combined. A controller makes WGV diagnosis for diagnosing whether or not a waste gate valve is normally controllable by issuing an instruction to a WGV actuator while the controller stops combustion in the engine and controls the MG1 and the MG2 in coordination to perform motoring of the engine during traveling of the hybrid vehicle.
