Patent number: 7899593Abstract: Provided are an automatic transmission abnormality diagnosis apparatus and method for an automatic transmission having: a lock-up mechanism; a shift mechanism; and a control mechanism. The automatic transmission is adapted to operate in a slip state, a full lock-up state or a lock-up release state of the lock-up mechanism. The lock-up mechanism is forcibly shifted from the slip state or from the lock-up release state to the full lock-up state in an operation region where the lock-up mechanism is not normally placed in the full lock-up state, and then whether the forcible shift of the lock-up mechanism has been successfully performed is determined. As such, the region for executing the abnormality diagnosis of the hydraulic control mechanism is extended and thus the frequency of the abnormality diagnosis increases, and therefore abnormalities can be promptly detected.Type: GrantFiled: January 28, 2008Date of Patent: March 1, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masayasu Mizobuchi, Kei Kitajima, Naoyuki Sakamoto

Patent number: 7074158Abstract: A shift control apparatus of an automatic transmission of a motor vehicle to which torque is transmitted from an engine via a fluid coupling device is provided. In the automatic transmission including a plurality of hydraulically operated friction elements, a clutch-to-clutch downshift is carried out during coasting of the vehicle by releasing one of the friction elements and engaging another friction element. A controller of the shift control apparatus detects a difference between input and output rotation speeds of the fluid coupling device, and increases an engine speed by a controlled amount based on the difference between the input and output rotation speeds when the clutch-to-clutch downshift is carried out during coasting of the vehicle, so that the vehicle is brought into a minimal driving state in which the engine speed is slightly higher than the output rotation speed of the fluid coupling device.Type: GrantFiled: April 12, 2004Date of Patent: July 11, 2006Assignees: Toyota Jidosha Kabushiki Kaisha, Aisin AW Co., Ltd.Inventors: Kazuyuki Watanabe, Toshimitsu Sato, Atsushi Ayabe, Shinji Kato, Naoyuki Sakamoto, Hiromichi Kimura, Noboru Shibata, Mitsuhiro Nakamura, Hideaki Ogasawara

Patent number: 6962552Abstract: A duty ratio for controlling an engagement force of a friction engagement device on the side of upshift engagement is corrected by an amount corresponding to an intermediate correction control value in the course of the shift. In addition, on a prerequisite condition that learning correction of a constant standby pressure control value at the start of the shift is converged, learning correction is performed for the intermediate correction control value according to a gradient of a turbine speed. Thus, a shift shock is prevented from occurring due to abrupt engagement of the friction engagement device and the like at the completion of the shift.Type: GrantFiled: July 31, 2002Date of Patent: November 8, 2005Assignee: Toyota Jidosha Kabushiki KaishaInventors: Naoyuki Sakamoto, Kazuyuki Watanabe, Toshimitsu Sato, Atsushi Ayabe, Hiromichi Kimura, Hideaki Ogasawara, Noboru Shibata, Mitsuhiro Nakamura

Patent number: 6941210Abstract: An apparatus for controlling ignition timing during a shift in a vehicular automatic transmission is provided that is capable of suppressing shift shock in the event that input torque of the automatic transmission is affected by external changes, such as changes in fuel and air pressure and the like, by adjusting immediately to those changes. This control apparatus is provided with an ignition timing controller that controls an ignition timing retard amount; a calculator that calculates a basic retard amount; a detector that detects an engine retard amount; a determinator that determines a retard correction value based on a shift mode of the automatic transmission and the like; and a corrector that corrects the ignition timing retard amount of the controller based on the retard correction value, the basic retard amount, and the engine retard amount.Type: GrantFiled: September 11, 2003Date of Patent: September 6, 2005Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takahiro Kondo, Toshimitsu Sato, Hisanori Nomoto, Naoyuki Sakamoto, Yoshiharu Harada, Toshio Sugimura, Masayasu Mizobuchi, Ryuji Imai

Patent number: 6893379Abstract: When it has been determined that control for a predetermined upshift has been started while an accelerator pedal was not being depressed, and that a factor that changes an input torque of an automatic transmission has been generated, an engaging pressure of a predetermined hydraulic frictional engagement device is corrected by a correction amount in accordance with the factor that changes the input torque. As a result, undershooting of an engine speed, as well as shift shock which results from that undershooting, is able to be preferably suppressed.Type: GrantFiled: August 13, 2003Date of Patent: May 17, 2005Assignee: Toyota Jidosha Kabushiki KaishaInventors: Naoyuki Sakamoto, Toshimitsu Sato, Hisanori Nomoto, Hiromichi Kimura, Toshio Sugimura, Masumi Wada
