    摘要: In control apparatus and method for an automatic transmission, an initial hydraulic reference value is calculated which provides a reference value of an initial hydraulic from a shift kind and a throttle opening angle or from the parameter value corresponding to the throttle opening angle and a correction quantity is calculated for the reference value of the initial hydraulic on the basis of squares of a revolution speed of a piston calculated and of the revolution speed of the piston detected, the initial hydraulic reference value being set to the initial hydraulic during the ordinary gear shift and the initial hydraulic reference value being corrected by a correction quantity to set the corrected initial hydraulic reference value to the initial hydraulic when the gear shift to a predetermined target gear shift stage is carried out at a drive point different from during the ordinary gear shift.

    摘要: A direct-coupling control method capable of improving fuel efficiency by performing slip direct-coupling control of a torque converter, in which a driving force transmission of an automatic transmission is operated under an approximate direct-coupling condition that permits slight slippage of the torque converter, in a predetermined operating range of the automatic transmission such as a low speed range thereof, and capable of positively detecting and preventing direct-coupling vibration caused by deterioration of hydraulic oil or the like. In the slip direct-coupling control, an occurrence of direct-coupling vibration is detected when a variation of a slip amount changing beyond predetermined upper and lower limit values is found a predetermined number of times during a predetermined period of time, or when a variation in the rotational rate of the output shaft of the torque converter still continues even after the slip direct-coupling control is interrupted for the reason that the rotational rate has varied beyond a permissible range. Upon detection of the direct-coupling vibration, the slip direct-coupling control is inhibited.
