Patent number: 11162449Abstract: The invention is related to a fuel pressure control device for an internal combustion engine, which controls a pressure of fuel supplied to a fuel injection valve and includes: a fuel pump, adopting the internal combustion engine as a driving source, and discharging pressurized fuel to a side of the fuel injection valve; a boost control part, setting a fuel discharge amount of the high-pressure fuel pump to a maximum value for boosting a pressure from a time when cranking starts until a predetermined timing halfway during a startup of the internal combustion engine; and a limit control part, performing limit control which follows the boost control and limits the fuel discharge amount to an upper limit.Type: GrantFiled: January 28, 2021Date of Patent: November 2, 2021Assignee: Honda Motor Co., Ltd.Inventors: Masahiro Yamada, Hirofumi Ohara, Takayoshi Okuda, Toshifumi Hiraboshi, Yoichi Kanou

Patent number: 9302670Abstract: In a control apparatus for a vehicle, an ECU includes an operation reception unit that receives depression of a power switch (i.e., a vehicle system activation operation is performed) in a “ready-off state” as a non-drivable state, and a control execution unit that executes, when the vehicle system activation operation is received by the operation reception unit during running of a hybrid vehicle HV and an engine is started, a startability improvement control for improving startability of the engine as compared with the startability thereof when the vehicle system activation operation is received by the operation reception unit during stop of the hybrid vehicle HV and the engine is started.Type: GrantFiled: December 18, 2012Date of Patent: April 5, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koji Yamamoto, Takayoshi Okuda, Hideaki Yaguchi, Toshiya Hashimoto

Patent number: 9216639Abstract: If the accelerator is on upon restarting a driving force source in travel mode by the time when the vehicle comes to a standstill after the driving force source is manually operated to stop while the vehicle is traveling, a control device for the vehicle implements first control in which the driving force output to the drive wheels is gradually increased. If the accelerator is on upon switching to the travel mode following restarting of the driving force source in the neutral mode and by the time the vehicle comes to a standstill after the driving force source is manually operated to stop while the vehicle is traveling, the control device implements second control in which the driving force output to the drive wheels is increased. The first control increases the driving force not as much as the second control increases the driving force.Type: GrantFiled: December 25, 2012Date of Patent: December 22, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koji Yamamoto, Takayoshi Okuda, Hideaki Yaguchi, Toshiya Hashimoto

Publication number: 20130175809Abstract: A hybrid vehicle includes a first motor-generator, which allows cranking an engine, and an inverter, which drives the first motor-generator. During running of the vehicle, when an operation to stop the hybrid system is performed, and then when an operation to start a hybrid system is performed before the vehicle stops, an HVECU operates the inverter.Type: ApplicationFiled: December 19, 2012Publication date: July 11, 2013Inventors: Koji YAMAMOTO, Takayoshi OKUDA, Hideaki YAGUCHI, Toshiya HASHIMOTO
