Patent number: 9821795Abstract: A hybrid vehicle includes an engine, a rotary electric machine, a filter and an ECU. The engine includes an exhaust passage. The rotary electric machine is a driving source of the vehicle. The filter traps particulate matter flowing through the exhaust passage. The ECU is configured to control the hybrid vehicle in any one of a plurality of control modes. The plurality of control modes include a first control mode and a second control mode. The number of opportunities for the engine to operate when the control mode is the second control mode is larger than the number of opportunities for the engine to operate when the control mode is the first control mode. The ECU is configured to, when the filter is regenerated, control the hybrid vehicle in the second control mode.Type: GrantFiled: January 26, 2015Date of Patent: November 21, 2017Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hidekazu Nawata, Tsukasa Abe, Toshio Inoue, Keita Fukui, Tomoaki Honda, Yuta Niwa, Taichi Osawa

Patent number: 8511278Abstract: An idling-time target phase setting unit (130) variably sets a target phase based on a target idle speed that is set by a target idle speed setting unit. (110) Especially, when the target idle speed is lower than a predetermined rotational speed and operating noise of a variable valve timing mechanism (2000) is easily heard by, for example, a driver, the.idling-time? target phase setting unit (130) sets the target phase so that a range, in which the valve phase is allowed to change, is restricted within a phase region where a speed reduction ratio is high and the operating noise is relatively low.Type: GrantFiled: April 11, 2008Date of Patent: August 20, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masayoshi Hattori, Tsukasa Abe
