Control device for hybrid vehicle

A control device for a hybrid vehicle including an engine with a supercharger, a first rotary machine that is able to adjust a rotation speed of the engine, and a second rotary machine and using the engine and the second rotary machine as drive power sources, the control device comprising:

• a high rotation curbing control unit configured to control the engine and the first rotary machine such that an operating point of the engine reaches a target operating point 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, the target operating point being 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 each of the engine and the first rotary machine and an output required for the engine is output from the engine;
• a supercharging pressure decreasing unit configured to decrease a supercharging pressure from the supercharger when a speed difference between the maximum rotation speed and the rotation speed of the engine is equal to or less than a set margin speed difference;
• and
• a torque compensation unit configured to compensate for a shortage of the output torque of the engine with respect to a required engine torque due to a decrease in the supercharging pressure by the supercharging pressure decreasing unit using a second rotary machine torque of the second rotary machine.
