Patent number: 9925981Abstract: A control unit for a vehicle comprises an automatic engine stop-and-restart unit for stopping the engine responsive to predefined stop conditions and for restarting the engine responsive to predefined restart conditions, and a following-cruise control unit for controlling the vehicle to follow a vehicle ahead responsive to predefined following-cruise conditions. The automatic stop-and-restart unit for stopping and restarting the engine is configured to modify at least one of the stop conditions and the restart conditions during the following-cruise control.Type: GrantFiled: February 5, 2014Date of Patent: March 27, 2018Assignee: HONDA MOTOR CO., LTD.Inventors: Masahiko Asakura, Hiroshi Yoneguchi, Tadayoshi Okada, Ryuji Sato, Kohei Hanada, Eisuke Horii, Yoshinari Sugita, Shunichi Kawasumi

Patent number: 9688254Abstract: A stop control system for a vehicle is provided, which is capable of stably performing cranking for restarting an internal combustion engine and positively preventing the vehicle from moving by properly increasing a braking force of the vehicle, during an idle stop. In the stop control system for a vehicle according to the present invention, the engine 3 is cranked by the starter motor 6 using the power supplied from the battery 7, when restart conditions are satisfied (step 8 in FIG. 5). Further, the stop control system includes a hydraulic pump 55 driven by the power supplied from the battery 7, for increasing the braking force of the vehicle V. During a stop of the vehicle V, it is determined whether or not the braking force of the vehicle V needs to be increased (FIG. 6), and the hydraulic pump 55 is controlled according to a determination result.Type: GrantFiled: November 13, 2012Date of Patent: June 27, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Eisuke Horii, Yoshinari Sugita, Shinichi Arai, Syumpei Tahara, Tomohiro Watanabe, Hiroshi Yoneguchi, Masahiko Asakura, Ryuji Sato, Takahiro Ohmi, Hideo Takeuchi

Patent number: 9463781Abstract: A stop control system for a vehicle, which is capable of positively preventing movement of a vehicle by positively increasing a braking force of the vehicle during an idle stop. In the stop control system for a vehicle of the present invention, the engine 3 is cranked by a starter motor 6 using power supplied from the battery 7 when restart conditions are satisfied during an idle stop (step 8 in FIG. 5). Further, the stop control system includes a hydraulic pump 55 driven by power supplied from the battery 7, for increasing the braking force of the vehicle V. During a stop of the vehicle V, when it is determined that the braking force of the vehicle V needs to be increased (F_BFREQ=1), the hydraulic pump 55 is activated. Further, if the restart conditions are satisfied during operation of the hydraulic pump 55, the cranking is inhibited to continue the operation of the hydraulic pump 55 (steps 6 to 9 in FIG. 5).Type: GrantFiled: November 13, 2012Date of Patent: October 11, 2016Assignee: HONDA MOTOR CO., LTD.Inventors: Eisuke Horii, Yoshinari Sugita, Shinichi Arai, Syumpei Tahara, Tomohiro Watanabe, Hiroshi Yoneguchi, Masahiko Asakura, Ryuji Sato, Takahiro Ohmi, Hideo Takeuchi

Patent number: 9224255Abstract: Provided are a vehicle configured such that if idling does not automatically stop, an in-vehicle display will occur immediately if a malfunction is the cause, thereby enabling a driver to have peace of mind and concentrate on driving, without giving the driver an unnecessary sense of unease; a vehicle diagnostic system therefor; and a vehicle diagnostic method. The vehicle comprises an idle stop error display unit provided corresponding to a specific ECU among a plurality of ECUs, and that indicates that an idle stop malfunction has occurred, being a malfunction corresponding to a second IS malfunction code, when a malfunction has occurred within a control target range for any among the plurality of ECUs, said malfunction recording the second IS malfunction code which does not cause the operation of a warning light requesting inspection or repair of an error that has occurred inside the vehicle.Type: GrantFiled: October 9, 2012Date of Patent: December 29, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Kensuke Yagi, Ryuji Sato, Hiroshi Yoneguchi, Masahiko Asakura

Patent number: 9188070Abstract: A vehicle stop control system capable of finely and properly determining traveling of a vehicle in a traffic jam to permit or inhibit automatic stop according to the determination result to ensure the effect of fuel economy improvement by automatic stop and avoiding inconveniences caused by frequent execution of automatic stop and restart. The system sets a precondition vehicle speed satisfaction flag to 1 when a vehicle speed becomes not lower than a precondition speed after an internal combustion engine was automatically stopped to permit automatic stop. Further, time after the vehicle speed passed a jam determination speed and until the vehicle speed passes the same again is acquired as passing time. When the passing time is shorter than a predetermined time period, the system determines that the vehicle is traveling in a jam, and resets the flag to 0 to inhibit automatic stop.Type: GrantFiled: February 3, 2014Date of Patent: November 17, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Masahiko Asakura, Hiroshi Yoneguchi, Ryuji Sato

Patent number: 5797450Abstract: A base plate 20 is provided with an oil inflow hole 20b in the form of a through-hole. The oil inflow hole 20b includes an area overlapping oil inlet communication holes 1 of plates 5 within a region inside an annular grove 20a of the base plate 20, and has a planar shape extending beyond the outer rim of the overlapping area. Thus, in the base plate constituting a contact end when the oil cooler is mounted to the engine block, a decrease in communication resistance of the oil communication hole provided therein as well as a smooth circulation of oil is achieved.Type: GrantFiled: April 29, 1997Date of Patent: August 25, 1998Assignees: Honda Giken Kogyo Kabushiki Kaisha, Toyo Radiator Co., Ltd.Inventors: Tsuyoshi Kawabe, Hiroshi Yoneguchi, Atsushi Arisaka, Takahiro Kuwabara, Tadamichi Aoyama
