摘要: An automatic transmission includes a frictionally engaging element for establishing a predetermined speed range. This predetermined speed range may be a second or higher speed range, and it is set temporarily in N-D squat control and also used for establishing a reverse range. In this transmission, engagement-actuation control of the frictionally engaging element for establishing the predetermined speed range which is executed when a shift is made from a N range to a R range comprises a plurality of control stages. When a shift to the R range is made via the N range following a N-D shift, a shift control apparatus detects the engagement condition of the the frictionally engaging element for establishing the predetermined speed range, selects one of the control stages in correspondence with the engagement condition, and initiates the engagement-actuation control of the frictionally engaging element from the control stage selected, so as to execute an engagement control for establishing the reverse range. Thus, in-gear shifts are executed smoothly without any delay in a N-D-N-R range shift.

摘要: An automatic transmission comprises a metal V-belt mechanism 10, which changes the speed ratio of the rotational output from an engine ENG, a forward/reverse direction change mechanism 20, which switches the rotational direction of the ratio-change mechanism, and a forward clutch 30, which actuates the switching operation of the rotational direction performed by the forward/reverse direction-change mechanism. A control system for this transmission comprises a regulator valve 50, which generates a line pressure, a manual valve 80, which is operated in correspondence to the shift lever and switches the supply of the line pressure to the forward clutch, and a drive-range sensor 105, which detects the operation of the manual valve. When the movement of the manual valve to a position where the line pressure is to be supplied to the forward clutch is detected by the drive-range sensor 105, the line pressure, which is adjusted by the regulator valve, is lowered for a predetermined time period.
