Patent number: 6102825Abstract: A rotational direction of a rotational element at a high speed gear stage is different from a operational direction of a reaction torque at a low speed gear stage. The rotation by the reaction torque at the low speed gear stage is stopped with a self-energizing operation of a band brake operated by a hydraulic servo. A waiting pressure, which is lower for a predetermined amount than a engagement pressure at the self-energizing operation, and with which a basis of a racing amount occurs after a synchronizing point, is applied to the hydraulic servo until the synchronization is determined. The waiting pressure increases to the engagement pressure after determining the synchronization so that the rotational element is stopped gradually as preventing a long shift time.Type: GrantFiled: March 16, 1999Date of Patent: August 15, 2000Assignee: Aisin AW Co., Ltd.Inventors: Takayuki Hisano, Masahiro Hayabuchi, Satoru Kasuya, Tatsuya Iida

Patent number: 5836852Abstract: Uncomfortable travel of a vehicle due to engine brake actions during the travel of the vehicle in traffic is prevented without using an one-way clutch within a transmission mechanism. An automatic transmission is composed of rotational elements that are braked at the time of establishing low stages, a brake that brakes the rotational elements, and control systems which control the oil pressure of the hydraulic servo in the brake. A band brake that creates differences in application forces, using self-energizing and deenergizing actions, serves as the brake, which is set to have an area in which the oil pressure during the drive is lower than the oil pressure during the non-drive, by setting the self-energizing direction as a direction of rotation of the rotational element during the drive and the deenergizing direction as an opposite direction of rotation of the rotational element during the non-drive.Type: GrantFiled: December 20, 1996Date of Patent: November 17, 1998Assignee: Aisin AW Co., Ltd.Inventors: Hiroshi Tsutsui, Kazumasa Tsukamoto, Masahiro Hayabuchi, Takayuki Hisano, Nobutada Sugiura

Patent number: 5807207Abstract: In order to improve transmission efficiency of an automatic transmission, an engagement brake which does not cause drag is used and the surety of its engagement and release, and quick switching between forward maneuver and backward maneuver, is enabled. The automatic transmission comprises a transmission mechanism to achieve forward maneuver and backward maneuver. A backward motion brake which stops the rotation element to achieve backward maneuver is the engagement brake and an input clutch to transfer power by meshing with the rotation element during both forward maneuver and backward maneuver is a friction clutch. The control apparatus executes the control operation to prepare for speedy re-meshing by holding a supply pressure for the clutch hydraulic servo at a sufficient oil pressure to place the pressure in the stand-by condition at the piston stroke position immediately before the start of clutch engagement during the engagement or releasing of engagement of the engagement brake at the time of D.Type: GrantFiled: December 20, 1996Date of Patent: September 15, 1998Assignee: Aisin AW Co., Ltd.Inventors: Takayuki Hisano, Kazumasa Tsukamoto, Masahiro Hayabuchi, Hiroshi Tsutsui
