Publication number: 20160257296Abstract: A controller for a hybrid vehicle is a controller used for a hybrid vehicle that is equipped with an internal combustion engine, a rotating electric machine, and an electric storage device, and that is capable of an external power supply. The controller includes a required-power information obtaining section that obtains required power, and a control section that controls the hybrid vehicle so as to cause the internal combustion engine to drive the rotating electric machine in order to supply power generated by the rotating electric machine to the outside of the hybrid vehicle without charging the electric storage device, when the required power is greater than predetermined power.Type: ApplicationFiled: October 14, 2014Publication date: September 8, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keita FUKUI, Hidekazu NAWATA, Toshio INOUE, Shunsuke FUSHIKI, Tomoaki HONDA, Yuta NIWA, Taichi OSAWA

Patent number: 9428180Abstract: A failure diagnosis apparatus comprises a controller that is configured to execute a failure diagnosis process of the internal combustion engine based on a predetermined diagnosis requirement. The diagnosis requirement in a case where engine-operation-electric-power supply is executed is made different from the diagnosis requirement in a case where engine-normal-operation is executed such that a failure of the internal combustion engine in the case where the engine-operation-electric-power supply is executed is less likely to be detected or the failure of the internal combustion engine is less likely to be recognized by a driver than in the case where the engine-normal operation is executed.Type: GrantFiled: March 13, 2013Date of Patent: August 30, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shunsuke Fushiki, Makoto Yamazaki, Keita Fukui

Publication number: 20160186699Abstract: In pressure increasing control for raising a pressure within a sealed type fuel tank from an excessive negative pressure to a low negative pressure, an opening or closing operation of a sealing valve, when the interior of a vehicle is very quiet, may cause the working noise thereof to be transmitted to a passenger, thereby deteriorating the noise characteristic. When the pressure within a fuel tank is below a predetermined negative pressure near a saturated vapor pressure of the fuel and an interior noise level is equal to or greater than a threshold value, a controller may operate a sealing valve to thereby raise the pressure of the fuel tank to a normal negative pressure region which may be higher than the predetermined negative pressure.Type: ApplicationFiled: December 17, 2015Publication date: June 30, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keita FUKUI, Yusaku NISHIMURA, Tatsuhiko AKITA

Publication number: 20150344023Abstract: A control unit for a hybrid vehicle determines whether warming of an engine is insufficient in an outside electric power feed mode. When the warming of the engine is insufficient, it is determined whether current time is in an initial period of electric power feed. When the current time is in the initial period of the electric power feed, only electric power of an electric storage device is supplied to the outside in a state that the engine is off. When the current time is not in the initial period of the electric power feed, the engine is turned on, and only electric power generated in a motor is supplied to the outside. When the warming of the engine is sufficient, the electric power generated in the motor, the electric power of the electric storage device, or both of them are supplied to the outside.Type: ApplicationFiled: May 27, 2015Publication date: December 3, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toshio INOUE, Shunsuke FUSHIKI, Tomoaki HONDA, Keita FUKUI, Hidekazu NAWATA, Yuta NIWA, Taichi OHSAWA

Patent number: 9188100Abstract: The invention relates to a control apparatus for a hybrid system that output engine drive force and electric motor drive force, and selectively performs an engine operation mode in which at least the engine is operated, and an engine operation stop mode in which engine operation is stopped. In cases where release of vaporized fuel captured in a vaporized-fuel capturing/releasing device is required, when the engine is being operated, release of vaporized fuel is started if there is no abnormality in the vaporized-fuel capturing/releasing device, and operation of the engine is continued to release the vaporized fuel until condition for terminating release of the vaporized fuel is satisfied; and in cases where release of the vaporized fuel is required, when the engine is not being operated, operation of the engine is started and release of the vaporized fuel is started if there is no abnormality in the vaporized-fuel capturing/releasing device.Type: GrantFiled: November 6, 2012Date of Patent: November 17, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventor: Keita Fukui
