摘要： An automatic transmission includes a multi-speed transmission gear mechanism having an input shaft, an output shaft and a plurality of friction coupling elements. A hydraulic control system selectively supplies a hydraulic pressure to the friction coupling elements, thereby selectively applying the friction coupling elements to cause the transmission gear mechanism to shift to a speed which is determined according to a predetermined shift pattern. The control system sets a target hydraulic pressure to be applied to the friction coupling elements according to the kind of the shift to be effected and the engine load, and, when it is detected that the transmission gear mechanism is to make a backout upshift due to reduction in the engine load, increases the target hydraulic pressure by an amount which is determined according to the throttle opening and the turbine speed.

摘要： A control apparatus for an engine and an automatic transmission controls a starting timing, a terminating timing, or methods of torque reduction of the engine during gear shifts. Using stored information such as a turbine speed signal, a gear shift signal, a degree to which a throttle valve is opened, a vehicle speed, an engine speed and so on, the control apparatus calculates an appropriate torque reduction which is performed by either retarding ignition timing or cutting fuel supplied to fuel injection valves. According to one embodiment of the invention, by detecting a variation ratio or differential value of turbine speed, a period of the torque reduction is started, ended, and kept within a proper timing. According to another embodiment of the invention, based on a "chasing" state of an input torque of the transmission against the variation of engine load, the timing of torque reduction is changed. Finally, according to yet another embodiment of the invention, a light preceding torque reduction is performed prior to a more significant torque reduction, but only when shocks due to the gear shift tend to occur.

摘要： An automatic transmission shift control system includes a hydraulically controlled valve mechanism for connecting and disconnecting a supply of hydraulic pressure to frictional coupling elements. Connection and disconnection of the hydraulic pressure supply locks and unlocks the frictional coupling elements in order to automatically shift an automatic transmission into desired gears. A time regulator regulates a duration time for which the valve mechanism is kept actuated and with which a speed at which the frictional coupling element is locked changes. The time regulator is controlled so as to variably regulate the duration time according to conversion efficiency of a torque converter. This conversion efficiency is, for example, determined from a speed conversion ratio and a torque conversion ratio.

摘要： A lockup torque converter of an automatic transmission for an automotive vehicle consists of an impeller connected to an engine, a turbine connected to the automatic transmission, and a lockup clutch disposed between first and second pressure chambers formed in a housing of said lockup torque converter for locking and releasing the lockup torque converter. A control unit supplies a hydraulic pressure into the first pressure chamber and withdraw a hydraulic pressure chamber from the second pressure chamber or reversely so as to actuate the lockup clutch to lock or unlock the lockup torque converter, respectively. A pressure regulating unit develops a pressure difference between the first and second pressure chambers when the shifting of the automatic transmission is detected, thereby causing the lockup clutch to allow the lockup torque converter to slip in accordance with certain conditions.

摘要： A line pressure control system for an automatic transmission, including a multiple shift stage transmission gear mechanism having a plurality of power transmitting paths of different speed ratios, has a line pressure control device for controlling a line pressure for frictional elements of the transmission gear mechanism associated with each other to establish a desirable shift gear stage. A shift period detector detects a time period for a shift operation, accomplished in terms of operation of the frictional elements controlled by the line pressure. A first compensating device controls the line pressure in terms of a learing control in a manner such that the time period for the shift operation is controlled to a target value. An abnormality detecting device detects an abrupt change, such as a turbine speed rise or, depression, or a driving torque depression in an operating condition of the transmission. A second compensating device compensates the line pressure prior to compensation of the line pressure by the first compensating device when the abrupt change is detected. The torque shock can be effectively obviated during a shift operation.

摘要： An automatic transmission has a transmission gear mechanism and a plurality of friction coupling members which are applied or released by hydraulic pressures applied thereto under the control of a hydraulic control system. The control system includes a hydraulic control circuit which controls the hydraulic pressure fed to or discharged from the respective friction coupling member, thereby changing the condition of application of the friction coupling members and causing the automatic transmission to shift. The plurality of friction coupling members includes first and second friction coupling members the conditions of application of which are changed during gear shifting from a first predetermined gear speed to a second predetermined gear speed. The first and second friction coupling members are fed with the hydraulic pressure respectively through first and second hydraulic passages. The hydraulic control circuit is provided with a pressure regulator valve which receives the pressure in the first hydraulic passage as a pilot pressure and regulates the hydraulic pressure to be fed to the second friction coupling member through the second hydraulic passage according to the pilot pressure.

摘要： A control system for a torque converter includes a lock-up clutch provided in a torque converter for connecting an input member and an output member of the torque converter directly. An engaging and disengaging hydraulic device controls an engaging and disengaging action of the lock-up clutch. A shift valve provided with a first and second spools in series controls introduction of a driving hydraulic pressure into the hydraulic device. The first spool of the shift valve is subjected to a first hydraulic pressure at one end, while the second spool is subjected to a second hydraulic pressure at the other end. The first and second spools are subjected to a third hydraulic pressure therebetween. The control system further includes a first control device for controlling the first hydraulic pressure, a second control device for controlling the second hydraulic pressure, an adjusting valve for adjusting the driving hydraulic pressure introduced into the engaging or disengaging hydraulic device, and a third control device for controlling a hydraulic pressure for controlling the adjusting valve. Converter, lock-up and slip conditions of the torque converter can be selectively established by switching shift positions of the single shift valve.
