Patent number: 8636621Abstract: A control device of a vehicle includes: power dividing mechanism that has a plurality of rotating elements rotated by torque output and transmitted from an engine and a first motor/generator and switches a transmission mode according to the engaging states of the respective rotating elements; and a clutch that has a first engaging member and a second engaging member having a backlash between them in a rotating direction thereof, and that sets a transmission mode to a fixed transmission ratio mode by engaging the first engaging member connected to one of the rotating elements with the second engaging member, and sets the transmission mode to a continuously variable transmission ratio mode by releasing the engagement. In the control device of a vehicle, the magnitude of the reversed rotating torque is reduced when the direction of rotating torque acting between the first and seconds engaging members.Type: GrantFiled: July 8, 2009Date of Patent: January 28, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiromichi Kimura, Yukihiko Ideshio, Hiroaki Ebuchi, Tomohito Ono, Hirotatsu Kitabatake, Hideki Sano

Patent number: 8041488Abstract: A method and apparatus for determining a motion transmission value that provides security of motion transmission between two components that transfer motion through frictional engagement. The motion transmission value provides security of motion transmission through the reaction of the motion transmitted to a change in the contact force between the components that are frictionally engaged. The contact force is modulated in a predetermined frequency range during the motion transmission, and the change in the motion transmitted during the modulation of the contact force is detected. The change in the motion transmitted is evaluated using a filtering process, and the motion transmission value is determined as the result of the evaluation.Type: GrantFiled: November 26, 2005Date of Patent: October 18, 2011Assignee: LuK Lamellen und Kupplungsbau Betelligungs KGInventor: Michael Reuschel

Patent number: 7698042Abstract: In response to the driver's brake OFF operation after a gearshift operation of a gearshift lever to a parking position, a motor MG2 is controlled to sequentially output a torque in a backward direction of a vehicle and a torque in a forward direction of the vehicle. Gears are accordingly engaged in a parking lock mechanism during rotation of a parking gear by an angle corresponding to half a tooth in the backward direction of the vehicle or during subsequent rotation of the parking gear by an angle corresponding to one tooth in the forward direction of the vehicle. This arrangement effectively ensures gear engagement in the parking lock mechanism, while desirably reducing a moving distance from a vehicle stop position before gear engagement in the parking lock mechanism.Type: GrantFiled: August 30, 2005Date of Patent: April 13, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yasuo Shimizu, Hideto Watanabe

Patent number: 7647154Abstract: A method and article of manufacture are provided for operating an internal combustion engine adapted to transmit torque to a hybrid transmission. The method comprises determining engine input torque transmittable to the hybrid transmission for a plurality of engine states the engine states comprising an all-cylinder operation and a cylinder-deactivation operation. Costs are determined for operating the engine and hybrid transmission in the engine states to substantially meet an operator torque request. The engine state is controlled to one of the all-cylinder operation and the cylinder-deactivation operation based upon the costs.Type: GrantFiled: September 26, 2007Date of Patent: January 12, 2010Assignee: GM Global Technology Operations, Inc.Inventor: Anthony H. Heap

Publication number: 20040162183Abstract: Hydraulic control system and method for an automatic transmission. The hydraulic control system includes a hydraulic pressure source, a flow rate control valve having a spool with an orifice and a drain hole, stroke position determining means, and pressure regulator means. The stroke position determining means determines that the spool is displaced from a large spool-stroke position where a communication area of the drain hole is not less than a first predetermined area, to a small spool-stroke position where the communication area is not more than a second predetermined area. The pressure regulator means regulates a hydraulic oil pressure downstream of the orifice and corrects the hydraulic oil pressure downstream of the orifice by adding a predetermined correction amount for a first predetermined time when the stroke position determining means determines that the spool is displaced from the large stroke position to the small stroke position.Type: ApplicationFiled: November 25, 2003Publication date: August 19, 2004Applicant: JATCO LtdInventors: Tatsuo Wakahara, Yoshihisa Kodama, Masahiro Yamamoto, Taichirou Yokoyama

Patent number: 6217469Abstract: A control system controls a line pressure applied to a CVT upon taking account of a certrifugal pressure caused by a rotation of pulleys. The control system determines whether the centrifugal pressure is greater than a predeterminied value only by which the pulley transmits an input torque from an engine. When the determination is affirmative, a lower limit of a duty ratio for operating a line pressure control valve is switched from a lower limit of a linear range to 0% duty ratio. Therefore, an actual transmissiou ratio control range is expanded while preventing an undershoot of the line pressure.Type: GrantFiled: July 16, 1998Date of Patent: April 17, 2001Assignee: Nissan Motor Co., Ltd.Inventors: Makoto Sawada, Hirofumi Okahara
