Control device for hybrid vehicle

A control device for a hybrid vehicle including an engine with a supercharger and a rotary machine that is able to adjust a rotation speed of the engine, the control device comprising:

• a high rotation curbing unit configured to control the engine and the rotary machine such that an operating point of the engine reaches a target operating point which is set such that the rotation speed of the engine is within a range which does not exceed a maximum rotation speed with a margin of the rotation speed of the engine from a predetermined upper-limit rotation speed of the engine and an output required for the engine is output from the engine and to control the engine such that an output torque of the engine decreases when the rotation speed of the engine exceeds the maximum rotation speed;
• a condition determining unit configured to determine whether a vehicle condition is a predetermined vehicle condition in which the rotation speed of the engine is likely to exceed the maximum rotation speed;
• and
• a supercharging curbing unit configured to further curb supercharging by the supercharger when it is determined that the vehicle condition is the predetermined vehicle condition in comparison with a case in which it is determined that the vehicle condition is not the predetermined vehicle condition.
