Abstract:
1. A control device for a hybrid vehicle including an internal combustion engine and a motor each for generating vehicle driving power, wherein an operation region indicated by rotational speed and torque of said internal combustion engine includes a first operation region in which a fuel injection amount is calculated in accordance with a stoichiometric air-fuel ratio, and a second operation region in which an amount of fuel is increased to exceed the fuel injection amount that is in accordance with said stoichiometric air-fuel ratio so as to suppress temperature increase of a catalyst provided in an exhausting system of said internal combustion engine, and said control device calculates a total required power of said hybrid vehicle in accordance with a vehicle state, determines an output power of said internal combustion engine such that the torque and the rotational speed of said internal combustion engine are included in said first operation region in all vehicle states, and determines an output power of said motor based on the output power of said internal combustion engine so as to secure said total required power.
