Patent 10293811 was granted and assigned to NISSAN MOTOR CO.,LTD. on May, 2019 by the United States Patent and Trademark Office.
A power generation control device is provided for a hybrid vehicle that prevents unintended engagement of a released engagement clutch during idle power generation. An internal combustion engine is operated during idle power generation so that the input-output differential rotation speed of engagement clutches for selectively connecting an electric motor and/or the internal combustion engine to the drive wheel becomes a value greater than or equal to a rotation difference threshold value at which the engagement clutches are not engaged.
