A hybrid vehicle control device is provided with an engine stop control means (1,2,5,7,10) and a fuel injection control means (1,2,5,7,10). The engine stop control means (1,2,5,7,10) is configured to issue an engine speed reduction command to reduce an engine speed of an engine (Eng) during an engine stopping operation occurring in response to establishment of an engine stop condition by using an electric motor (MG) and slip engaging a drive-wheel side clutch (CL2) disposed between the electric motor (MG) and a drive wheel (LT,RT) such that the drive-wheel side clutch (CL2) transmits rotational torque between the electric motor (MG) and the drive wheel (LT,RT). The fuel injection control means (1,2,5,7,10) is configured to issue a fuel injection command to continue fuel injection during the engine stopping operation until the engine speed decreases below a prescribed engine speed whereupon the fuel injection is stopped. This prevents a catalytic converter (25) from entering a lean state, which has adverse effects on NO x emissions during engine restart. |
