Publication number: 20220153260Abstract: A controller detects partitioning lines OL and BL of a road and a road edge E based on an image taken by a camera, generates a pair of left and right virtual lines ILL and ILR that extend from the side to the front of a vehicle along the partitioning lines OL and BL, controls the steering so the vehicle travels between the left and right virtual lines ILL and ILR, moves the left virtual line ILL to a position in proximity to the road edge E and fixes the left virtual line ILL to this position, and then, moves the right virtual line ILR to a position separated from the left virtual line ILL by the width of the vehicle and fixes the right virtual line ILR to this position, and controls brakes to stop the vehicle after fixing the left and right virtual lines ILL and ILR.Type: ApplicationFiled: November 9, 2021Publication date: May 19, 2022Applicant: Mazda Motor CorporationInventors: Takashi HAMADA, Yuma NISHIJO, Kouichi KOJIMA, Yoshiyuki YAMASHITA, Yuta TSUJI, Hiroshi OHMURA, Takashi GOTO, Shoji HARADA, Kenta TADA, Kazuki SATO

Patent number: 8705226Abstract: A capacitor includes a film previously provided on both sides or one side of a collector by anodizing or the like, further a conductive layer provided on the film, and a polarizable electrode layer as an electrode portion on the conductive layer. Thus, the capacitor suppresses the reaction between a driving electrolyte and the collector after a long time of use because the reactivity between the film previously provided on both sides or one side of the collector and the driving electrolyte is low. Furthermore, since the conductive layer is provided, it is possible to reduce an initial contact resistance on the surface of the collector, and to enhance an effect of suppressing performance deterioration by the film.Type: GrantFiled: September 17, 2009Date of Patent: April 22, 2014Assignee: Panasonic CorporationInventors: Keisuke Imamura, Kouichi Kojima

Patent number: 6955629Abstract: A shift control apparatus has first, second, third and fourth engagement elements, and a shift control processing unit engaging the first and the second engagement elements in order to realize a first shift speed, engaging the third and the fourth engagement in order to realize a second shift speed, and inhibiting an increase in torque capacity of one of the first and second engagement elements before starting of release of the second engagement element when shifting from the first to the second shift speed. During shifting from the first to the second shift speed, an increase in torque capacity of one of the first and second engagement elements is inhibited before starting of release of the second engagement element. This prevents a step-like shift shock from being caused by the slowed progression of shifting when release of the second engagement element is started.Type: GrantFiled: April 2, 2003Date of Patent: October 18, 2005Assignee: Aisin Aw Co., Ltd.Inventors: Masaaki Nishida, Hiroshi Tsutsui, Kouichi Kojima, Yutaka Teraoka, Masatake Ichikawa, Hidekazu Funakoshi

Patent number: 6832976Abstract: An automatic transmission achieves a desired shift through an initial stage shift in which a first engagement element is released and a third engagement element is engaged, and a final stage shift in which a second engagement element is released and a fourth engagement element is engaged. A control apparatus sets an estimated rotation acceleration for a transmission input shaft in accordance with an input torque and an input torque rotation acceleration speed, and controls the release of the second engagement element for moving to the final stage shift according to the estimated rotation acceleration. As a result, it is possible to prevent a shifting delay and/or degradation that occurs between the initial stage and the latter stage by continuous transmission of the input rotation (engine rotation) change when moving from the initial stage to the later stage.Type: GrantFiled: April 14, 2003Date of Patent: December 21, 2004Assignee: Aisin AW Co., Ltd.Inventors: Masaaki Nishida, Hiroshi Tsutsui, Kouichi Kojima, Yutaka Teraoka, Kiyoshi Akutsu

Patent number: 6755767Abstract: The invention has been made to eliminate a feeling of two-phase speed-change operations by causing a speed-change operation to proceed continuously when the speed-change operation is performed through two-phase control of engagement and release of four engagement elements. To accomplish this purpose, the invention provides a control apparatus for an automatic transmission wherein a predetermined speed-change operation is achieved through a pre-phase speed-change operation in which a first engagement element and a third engagement element are released and engaged respectively and through a post-phase speed-change operation in which a second engagement element and a fourth engagement element are released and engaged respectively. The control apparatus sets a target rotational acceleration of an input shaft of the transmission, and controls release of the second engagement element for a transition to the post-phase speed-change operation in accordance with the target rotational acceleration.Type: GrantFiled: April 11, 2002Date of Patent: June 29, 2004Assignee: Aisin AW Co., Ltd.Inventors: Masahiro Hayabuchi, Masaaki Nishida, Hiroshi Tsutsui, Kouichi Kojima, Yutaka Teraoka, Nobuhiro Iwai, Kiyoshi Akutsu

Patent number: 6719657Abstract: A lock-up control apparatus for an automatic transmission in which operations of four engagement elements are required when shifting is performed from a first shift speed to a second shift speed, the first shift speed being achieved by engagement of a first engagement element and a second engagement element, the second shift speed being achieved by engagement of a third engagement element and a fourth engagement element. The lock-up control apparatus includes a lock-up control unit that performs a control for bringing a lock-up clutch into one of a disengagement state and a slip state at a start of shifting, and that prevents reengagement of the lock-up clutch at a completion of engagement of the third engagement element when shifting is performed from the first shift speed to the second shift speed during lock up.Type: GrantFiled: October 25, 2002Date of Patent: April 13, 2004Assignee: Aisin AW Co., Ltd.Inventors: Masaaki Nishida, Hiroshi Tsutsui, Kouichi Kojima, Yutaka Teraoka, Masaki Nishide

Patent number: 6626786Abstract: At the time of the 6→3 speed shift, an automatic transmission achieves a 6→4→3 speed shift by controlling the servo pressures of four engageable elements. A control apparatus controls the servo pressure of one engageable element in accordance with the servo pressures of other engageable elements. The engagement and release timings are adjusted by determining and controlling the oil pressures of the hydraulic servos, taking into consideration the 6→4 shift state (torque sharing) during a shift transitional period. Therefore, engine blow and prolongation are prevented during the 6→3 shift control.Type: GrantFiled: November 29, 2001Date of Patent: September 30, 2003Assignee: Aisin AW Co., Ltd.Inventors: Masahiro Hayabuchi, Masaaki Nishida, Hiroshi Tsutsui, Kouichi Kojima, Yutaka Teraoka, Nobuhiro Iwai, Kiyoshi Akutsu
