Abstract: A shift control apparatus for an automatic transmission of a vehicle wherein a plurality of speed ratios are achieved by electronically controlling individual hydraulic pressures supplied to a plurality of frictional engaging elements to selectively engage these frictional engaging elements, which includes speed ratio select members for changing over the speed ratio of the automatic transmission from a neutral position to a running position, operation condition determination members for determining operation condition of the vehicle, an electromagnetic valve for controlling hydraulic pressure supplied to a first frictional engaging element to achieve a first speed; and electromagnetic valve control members for controlling operation of the electromagnetic valve so that when the speed ratio select members is determined by the operation condition determination means to be slowly manipulated, a supply time of a maximum hydraulic pressure to the first frictional engaging element is extended by a predetermined time

Abstract: Hydraulic pressure supplied to the frictional engaging element of an automotive transmission is corrected to a higher value in the event that the engine is started after a long standstill condition and the first speed ratio is selected, thereby reducing speed-shift shocks when the engine is started from a standstill condition and the first speed ratio is selected.

Abstract: 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.

Abstract: In an automatic transmission for a vehicle having at least one frictional engaging element and an electromagnetic valve to control hydraulic pressure supplied to the frictional engaging element and achieving a plurality of speed ratios including a predetermined speed ratio achieved by engaging the frictional engaging element, a shift control apparatus includes retardation rate detection means for detecting retardation rate of the vehicle and electromagnetic valve control means for controlling the electromagnetic valve according to the value detected by the retardation rate detection means, and hydraulic pressure supplied to the frictional engaging element is corrected by the electromagnetic valve through electromagnetic valve control means according to the retardation rate of the vehicle detected by the retardation rate detection means, thereby reducing speed-shift shocks during a down-shift in association with retardation of the vehicle.
