Patent number: 11084484Abstract: A hybrid vehicle control method is provided for a hybrid vehicle having an engine and a generator directly connected via a gear train having a plurality of gears that are engaged with each other. In this hybrid vehicle control method, a prescribed torque is continuously applied to the generator upon determining the engine is in a rotating state such that a transmission torque of the gear train does not continuously fluctuate above and below zero torque. Preferably, in one embodiment, the prescribed torque continuously applied to the second motor/generator is a negative torque value during a power generation operation in which the generator is rotated by the engine and is a positive torque value during a motoring operation in which the engine is rotated by the generator.Type: GrantFiled: September 6, 2016Date of Patent: August 10, 2021Assignee: Nissan Motor Co., Ltd.Inventors: Shinpei Kondo, Yusuke Ienaka, Hirotaka Kaneko, Tomohiro Ito, Yuusuke Satou
