Abstract
When an electrical continuously variable transmission malfunctions and the operation of an engine is stopped, an automatic transmission is caused to upshift. Therefore, when the rotation of the engine is stopped as a result of a stop of the operation, an AT input rotation speed is decreased as compared to that before it is determined that there is a malfunction in the electrical continuously variable transmission. Thus, an MGrotation speed is decreased in absolute value as compared to when the automatic transmission is not caused to upshift, so an overspeed of a first electric motor is prevented.
