Patent number: 9050974Abstract: Provided are a drive system and a method for controlling the drive system which reduce a shock to a third shaft at the start of an internal combustion engine during EV driving. The drive system includes an engine, a first shaft connected to a crankshaft, a second shaft, a first clutch, a motor generator, a third shaft, a first transmission, a one-way clutch, and an ECU for controlling a gear ratio of the first transmission and the first clutch. The first transmission includes a rotating ring, a rocking portion, and a rotation radius variation mechanism.

Patent number: 9045128Abstract: Provided is a drive system that enables a reduction in the rise time of foot axis torque even if the drive system has a one-way clutch. The drive system includes a one-way clutch between a transmission and an output shaft. When a coasting determination unit determines to perform a coasting control, a control unit executes the coasting control by reducing the engine rotation speed of an internal combustion engine or stopping the engine rotation to bring the one-way clutch into a non-transmission state, and changing the transmission gear ratio of the transmission to a transmission gear ratio smaller than the transmission gear ratio calculated by a calculation unit.Type: GrantFiled: May 21, 2012Date of Patent: June 2, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Mitsuhiro Iwadare, Satoshi Kodo, Tsunehiro Kobayashi
