Patent number: 10458492Abstract: An electronic control unit executes gradual reduction control when a friction clutch is to be maintained in a fully engaged state such that an input rotary member and an output rotary member rotate integrally. As a result, a motor current supplied to a motor is adjusted to a lower current value. Thus, an average current value of the motor current supplied to the motor when the friction clutch is to be maintained in the fully engaged state is appropriately reduced.Type: GrantFiled: May 31, 2018Date of Patent: October 29, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masayuki Arai, Satoshi Ishida, Shota Murai, Taito Goto

Patent number: 10449964Abstract: Variator (20) and forward clutch (Fwd/C) disposed in series are provided between engine (1) having starter motor (15) and driving wheel (7). Sailing stop control that, on the basis of satisfaction of sailing entering condition, interrupts power transmission by frictional engagement element (Fwd/C), stops engine (1) and performs coast-travel is performed. When sailing entering condition is satisfied, coast-travel is started with rotation stop timing of variator (20) being delayed with respect to rotation stop timing of engine (1). When accelerator pedal depression operation intervenes after start of coast-travel, engine (1) is restarted by starter motor (15). When judged that input and output rotation speeds of frictional engagement element (Fwd/C) become synchronization rotation speed after restart of engine (1), frictional engagement element (Fwd/C) is reengaged.Type: GrantFiled: October 17, 2016Date of Patent: October 22, 2019Assignee: JATCO LTDInventors: Tadashi Iwamoto, Akira Takano, Masayoshi Nakasaki, Yoshimasa Nishihiro, Yukifumi Ootsuka
