Abstract
When there is no malfunction in either drive shaft rotational speed detection portion () or rotating shaft rotational speed detection portion (), control of internal combustion engine (), the power split device (, MG), the electric motor (MG), and the shifting portion () is performed while speed ratio in shifting portion () is changed and an intermittent operation of internal combustion engine () is performed so that a drive power required for drive shaft () is output to shaft (). When a malfunction occurs in drive shaft rotational speed detection portion () or/and rotating shaft rotational speed detection portion (), the control is performed while at least one of change in speed ratio, intermittent operation, and output of drive power required for shaft () to shaft () is limited so that a drive power that approximates required drive power as closely as possible is output to drive shaft ().
