To provide a hybrid vehicle control device capable of properly suppressing deterioration of drivability.

A target engine speed (S104) is calculated based on a request total output power before being decreased, against a decrease (S101) in a request total output power, when an accelerator and a brake pedal are simultaneously stepped in (S100:YES). Accordingly, when a driver performs an accelerator operation and a brake operation at the same time, the output power of a hybrid system is decreased while maintaining an engine speed.
