Abstract
In a control method of an internal combustion engine exhaust gas control system which is applied to a hybrid vehicle that is powered by an internal combustion engine and an electric motor, an exhaust throttle valve, provided downstream of an exhaust gas control catalyst, is controlled to reduce its opening amount to a target opening amount when it is determined that warm-up control of the internal combustion engine needs to be executed. Next, a target injection quantity of fuel necessary to increase the temperature of exhaust gas flowing into the internal combustion engine to a target exhaust gas temperature is calculated. Then, assist torque from the electric motor is adjusted so that the sum of torque from the internal combustion engine when the fuel injection quantity has been set to the target injection quantity and the assist torque substantially equals a required torque.
