<P>PROBLEM TO BE SOLVED: To continue a travel for a longer period when opening fixation abnormality of a valve for supplying exhaust emission to an intake system of an engine occurs. <P>SOLUTION: When the opening fixation abnormality of the valve is decided, the engine is operated with a prescribed engine speed Nref, and the engine and two motors are controlled such that a charging travel wherein the travel is performed with request torque Tr* is performed while charging a battery (S140-S190). When a catalyst temperature Tc of a purification catalyst installed to an exhaust system of the engine becomes a threshold value Tth1 or above (S130), an opening of a throttle valve is made to be a prescribed opening THref (S220), and the engine and the two motors are controlled such that the travel is performed with the request torque Tr* while gradually reducing the engine speed of the engine by stopping fuel injection to the engine (S230-S250, S160-S190). Thereby, the travel can be continued for the longer period. <P>COPYRIGHT: (C)2010,JPO&INPIT |
