HYBRID VEHICLE CONTROL DEVICE

To provide a hybrid vehicle control device that is able to suppress an increase in the engine rotational speed when starting an engine and to prevent a deterioration of fuel consumption caused by starting the engine. The invention is mounted to a hybrid vehicle comprising an engine (Eng), a motor/generator (MG), a first clutch (CL1) provided to the connecting portion between the engine (Eng) and the motor/generator (MG), and an engine start control unit (10b) configured to make starting the engine (Eng) more difficult when the rotational speed of the motor/generator (MG) exceeds a first threshold value and a second threshold value, which are set in advance, as compared to when the rotational speed of the motor/generator (MG) is below the first threshold value and the second threshold value.
