摘要： In a shift control method, when a speed ratio of an automatic transmission is shifted from a third speed ratio to a first speed ratio before stoppage of a vehicle, a down shift line 3-1 in a shift pattern is shifted to a high-speed side to initiate shifting under a power-OFF condition. A third brake is released by setting the duty ratio of an electromagnetic valve of the third brake at 0% to establish a free condition (neutral condition) in an output shaft of a second transmission. While the duty ratio of an electromagnetic valve of a second clutch in a first transmission mechanism is set at 0%, the duty ratio of an electromagnetic valve of a second brake is gradually increased, so that the shifting from the second clutch to the second brake is made, and the first transmission mechanism is operatively shifted from the third speed ratio to a speed ratio corresponding to the first speed ratio. Then, the third brake is engaged again upon completion of the shifting and after mechanical engagement of a one-way clutch. Consequently, it is possible to reduce shocks in shifting the speed of the vehicle.

摘要： A hydraulic control method which includes a step of changing the time rate of introduction per a predetermined unit time of pressurized oil into an oil passage connected to a hydraulically-operated load device, such as a clutch of an automatic transmission, from a first time rate to a second time rate, thereby changing the time-based average oil pressure inside the oil passage from a first oil pressure value to a second oil pressure value. The time rate of introduction of the pressurized oil into the oil passage is changed from the first time rate to the second time rate via a third pressurized oil introduction time rate corresponding to a third oil pressure value different from the first and second oil pressure values. If the second oil pressure value is greater than the first oil pressure value, the third pressurized oil introduction time rate is substantially 100%. If the second pressure value is smaller than the first, the third time rate is substantially 0%. Preferably, the step of pressurized oil introduction into the oil pressure at the third pressurized oil introduction time rate is followed by at least one step of introducing the pressurized oil into the oil passage at a pressurized oil introduction time rate corresponding to an oil pressure value different from the third oil pressure value. Preferably, the pressurized oil introduction time rates are temperature-corrected in accordance with the pressurized oil temperature.

摘要： A speed change control and apparatus of an automotive automatic transmission causes a turbine rotational speed to change toward a synchronous rotational speed associated with a desired gear stage by engaging a connection-side clutch while disengaging a release-side clutch, to thereby carry out gear-changing. To reduce a speed change shock, a speed change time is rendered stabilized irrespective of vehicle running state, by carrying out feedback control such that the time-dependent change rate (Ns)' of a rotational speed difference between clutch plates and clutch discs of the connection-side clutch becomes equal to a target slip rotational speed change rate (Ni)'.

摘要： An operation control method for a frictional engagement element which includes engaging means and piston means for urging the engaging means to engage, the operation of the piston means being controlled by means of pressurized oil supplied through a hydraulic control device for producing an oil pressure of the level corresponding to the quantity of electricity supplied thereto. The relationship between the quantity of electricity supplied to the hydraulic control device and the stroke speed of the piston means is previously stored. An ineffective stroke amount of the piston means is detected from the sum total of the products of drive periods, based on the quantities of electricity supplied to the hydraulic control device while the piston means travels through an ineffective stroke section, and stroke speeds corresponding individually to the quantities of electricity. The stored value of the ineffective stroke amount of the piston means is updated to store the detected ineffective stroke amount. When the piston means is moved through the ineffective stroke section, the period for the electric power supply to the hydraulic control device is monitored in accordance with the updated ineffective stroke amount, and the arrival of the piston means at the position just short of the engagement start position is detected.

摘要： During downshift operation of an automotive automatic transmission in which a lower-speed clutch for establishing a lower-speed gear is engaged while higher-speed clutch, which has established a higher-speed gear, is disengaged, to increase the turbine rotational speed Nt toward a synchronous rotation speed Ntj associated with the lower-speed gear, speed change control is carried out according to the same control method regardless of whether the engine is in a power-on or power-off state. A target change rate (Nir)' of turbine rotational speed associated with the higher-speed clutch and a target change rate (Nia)' of turbine rotational speed associated with the lower-speed clutch are set, and a change rate (Nia)' of the turbine rotational speed is detected. The transmission torque through the higher-speed clutch is controlled in a feedback manner such that the detected change rate (Nt)' coincides with the change rate (Nir)'. Further the transmission torque through the lower-speed clutch is feedback-controlled such that the change rate (Nt)' coincides with the change rate (Nia)', thereby carrying out downshift.
