Abstract

Combustion operation of an internal combustion engine (2) a series hybrid vehicle is automatically stopped and automatically restarted according to a power generation request. It is determined whether or not a catalyst temperature at the time of a restart request is equal to or higher than a predetermined activation temperature (S1, S2). If the catalyst temperature is equal to or higher than the activation temperature, substantially simultaneously with a start of motoring of the internal combustion engine (S9), fuel injection and ignition are started (S8). If the catalyst temperature is lower than the activation temperature, a valve timing is changed (S3) and a throttle valve opening is increased (S4) so as to increase volumetric efficiency, and the motoring is started (S5). When an elapsed time t from the start of the motoring reaches a required delay time tD (S6, S7), fuel injection and ignition are started (S8).
