Patent number: 9340181Abstract: A belt member includes: a strip member having an elongate shape; a fastener disposed along the longitudinal direction of the strip member; and an opening-closing device that opens or closes the fastener. For reducing a contact pressure of the belt member per unit area, the fastener is opened by the opening-closing device to unfold the belt member into a form of a wide strip so that the width of the belt member is increased. On the other hand, when the fastener is closed by the opening-closing device, the belt member takes a form of a narrow tube so that the width of the belt member is reduced.Type: GrantFiled: February 18, 2015Date of Patent: May 17, 2016Assignees: TOYOTA BOSHOKU KABUSHIKI KAISHA, YKK CORPORATIONInventors: Masahiro Fukamoto, Atsuki Ito, Nobuhiro Yamada, Makoto Yamazaki, Yasuhiko Matsuda, Seiji Koga

Patent number: 9296384Abstract: A vehicle includes an internal combustion engine, a rotary electric machine that generates driving force for the vehicle, and a control unit that controls the internal combustion engine on the basis of a state of the vehicle. When the internal combustion engine is started in response to a request for the driving force, the control unit controls the internal combustion engine such that ignition timing of the internal combustion engine while a first mode is selected is later than the ignition timing while a second mode is selected. The vehicle is more likely to be driven using the rotary electric machine in a state where the internal combustion engine is stopped in the first mode than in the second mode.Type: GrantFiled: February 24, 2012Date of Patent: March 29, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Makoto Yamazaki

Patent number: 9050975Abstract: A vehicle includes an engine, a power storage device, a motor generator using electric power from the power storage device for generating driving force, and an ECU. The vehicle is capable of running with the operation mode selectively switched between the CS mode in which the vehicle runs utilizing the driving force from the engine and the motor generator, and the CD mode in which the vehicle runs preferentially utilizing the driving force from the motor generator in the state where the engine is stopped. When the OBD is performed for detecting a malfunction in the engine in the state where the CD mode is selected, the ECU keeps the operation mode being temporarily switched from the CD mode to the CS mode until the OBD is completed.Type: GrantFiled: January 27, 2011Date of Patent: June 9, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shunsuke Fushiki, Makoto Yamazaki

Patent number: 8694187Abstract: An ECU (Electronic Control Unit) that controls a plug-in hybrid vehicle starts an engine when a required power as a value obtained by subtracting a required discharge amount from a drive power is larger than a threshold during intermittent control in a CD (Charge Depletion) mode, and stops the engine when the required power is smaller than a threshold. When intermittent control is being performed in the CD mode, the ECU limits the required discharge amount Pout to a relatively small value in a range where an engine coolant temperature is low, and sets the required discharge amount relatively large instead of imposing a limit thereon in a range where the engine coolant temperature is high.Type: GrantFiled: July 28, 2010Date of Patent: April 8, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Makoto Yamazaki, Osamu Harada, Shunsuke Fusiki

Patent number: 8306720Abstract: In a power output apparatus, when the fuel vapor concentration is high and the target purge rate is high, an operating point on a purge priority operating line is selected as a target operating point of an engine. As a result, the intake manifold negative pressure greater than that when an operating point on an optimum fuel efficiency operating line is selected, so that the flow rate of purge gas released from a canister is increased. When the fuel vapor concentration does not fall within a high-concentration range, the necessity to immediately purge fuel vapor trapped in the canister into the intake pipe is low, and thus an operating point on the optimum fuel efficiency operating line is selected to keep the engine operating at high fuel efficiency.Type: GrantFiled: May 26, 2009Date of Patent: November 6, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Makoto Yamazaki, Shunsuke Fushiki
