Abstract
A hybrid vehicle system and control method for enhancing startup flare control includes receiving a start signal for starting an internal combustion engine from a start engine actuator and starting the internal combustion engine, increasing a throttle open angle in response to the start signal to increase engine speed upon starting of the internal combustion engine and, after a desired engine speed is reached, engaging an electric motor with the internal combustion engine to add a drag force on the internal combustion engine thereby rapidly reducing engine speed.
