摘要： A control system for an automatic transmission has a shift gear mechanism with a plurality of frictional elements, including a low reverse brake which is selectively actuated for switching a power transmitting path to establish a desired shift stage. A hydraulic control circuit controls supply of a hydraulic fluid to and relief of the fluid from an actuator for the frictional element. An accumulator is provided in a hydraulic passage communicated with the low reverse brake for obviating a shock as the low reverse brake is engaged. Back pressure of the accumulator is controlled when a first shift gear stage is established through the engagement of the low reverse brake. A torque shock can be suppressed when the first stage is established in an L-range.

摘要： A control system for a torque converter includes a lock-up clutch provided in the torque converter for connecting input and output members of the torque converter directly, and a shift valve having first and second spools disposed in series in a sleeve for shifting an introduction of an engaging and releasing pressure acting on the lock-up clutch in accordance with positions of the first and second spools. The first spool is subjected to a first hydraulic pressure at one end thereof. The second spool is subjected to a second hydraulic pressure at one end thereof opposite to the one end of the first spool. The first and second spools are subjected to a third hydraulic pressure therebetween. The control system further has a first control device for controlling the first hydraulic pressure, and an adjusting valve for controlling the releasing pressure of the lock-up clutch. The shift valve provides the first and second spools with first, second and third positions corresponding to a converter condition, lock-up condition and slip condition, respectively. The shift valve is shifted between the second and third positions when the releasing pressure is relatively low so that the releasing pressure is continuously changed irrespective of the shifting action among the first, second and third positions of the shift valve. An abrupt change in the engaging force of the lock-up clutch is prevented.

摘要： An automatic transmission control system for selectively locking and unlocking a plurality of frictional coupling elements is provided within an automatic transmission so as to place the automatic transmission into one of various possible gears. The control locks a specific one of the frictional coupling elements with locking pressure when the automatic transmission performs a specific gear shift and unlocks it by reducing the locking pressure when causing it to perform, an opposite gear shift reverse to the specific gear shift. The locking pressure is increased by way of a relatively high level of shelf pressure during the specific gear shift and reduced by way of a relatively low level of shelf pressure during the opposite gear shift.

摘要： The multistage transmission gear mechanism is provided with a first and second coupling means for shifting speed stages, each being of a type operable hydraulically and adapted to allow four speed stages from first to fourth speed stages to be selected in accordance with a combination between a coupled state and an uncoupled state of the first and second coupling means. A third coupling means is further provided for ensuring engine braking.The second coupling means is engaged or coupled by a first pilot pressure generated by a first solenoid at the second, third and fourth speed stages. The first coupling means is coupled by a second pilot pressure generated by a second solenoid at the third and fourth speed stages. The third coupling means is coupled at the second and third speed stages.A third solenoid is provided for generating a third pilot pressure which prevails over the first pilot pressure and controls shifting the second coupling means at the third speed stage.At shifting between the second and third speed stages, the second pilot pressure prevails over the first pilot pressure to being the second coupling means into a state of its shifting being controlled by the third pilot pressure. At this time, shifting the third coupling means is controlled by the first pilot pressure to avoid a temporary engagement of all the three coupling means, thus preventing a transmission shock.

摘要： A control apparatus for an automatic transmission has a control unit which, when a selector lever is shifted from a forward drive gear range to a reverse gear range when the vehicle speed is not lower than a first predetermined speed, prevents the gear stage from being changed to that corresponding to the reverse gear range until the vehicle speed has fallen to a speed not greater than a second predetermined speed lower than the first predetermined speed. The control unit allows the gear stage to be changed to that corresponding to the reverse gear range if the selector lever is shifted to the reverse gear range when the vehicle speed is lower than the first predetermined speed. This control apparatus, therefore, ensures that the gear stage can be changed to that corresponding to the reverse gear range only when the driver intentionally shifts the selector lever from one of the forward drive gear ranges to the reverse gear range.
摘要翻译：用于自动变速器的控制装置具有控制单元，当车速不低于第一预定速度时，当选档杆从正向驱动齿轮范围向后退档位移动时，防止齿轮级改变对应于倒档档位，直到车速下降到不低于第一预定速度的第二预定速度的速度。当车速低于第一预定速度时，如果选档杆移动到倒档档位，则控制单元允许齿轮级改变成与倒档档对应的档位。因此，该控制装置确保仅当驾驶员有意将换档杆从正向驱动齿轮范围中的一个移动到倒档时才能将齿轮级改变为与倒档档对应的档位。

摘要： In an automatic transmission, a second brake is engaged when the transmission is in second and is released when the transmission is in third and first. The second brake is controlled by a hydraulic actuator. Application of the hydraulic pressure to the hydraulic actuator of the second brake is limited upon upshift from first to second so that the hydraulic pressure is gently applied to the hydraulic actuator. The limitation of application of the hydraulic pressure is nullified upon downshift from third to second.

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： A fluid coupling for an automatic transmission includes an input element, an output element and a lockup clutch and is connected to a transmission mechanism. The lockup clutch can engage and disengage to operatively connect and disconnect the input element and the output element with and from each other. Further the lockup clutch can engage in slipping engagement to connect the input element and the output element in such a way as to allow the input element and the output element to rotate relative to each other to some extent. A control system causes the lockup clutch to engage in slipping engagement with a substantially fixed engaging force when the transmission mechanism upshifts while the lockup clutch is in slipping engagement, and to disengage when the transmission mechanism downshifts while the lockup clutch is in slipping engagement.
