- the fourth clutch C-4 Indicates the number of rotations of the intermediate rotating member 18, which is connectable to the carrier C1 by the engagement of the gear C1 and fixed to the transmission case 11 by the engagement of the first brake B-1.
- step 100 when -UTRAL range is determined based on the signal of range position sensor 34, in step 102, a standby pressure command is output to brake B-1 and brake B-1 is in standby mode. Operated with pressure PB1.
- This standby pressure PB1 is the minimum pressure necessary to stop the rotation due to the drag torque of the clutch C3 necessary for the reverse (R) formation, and is a pressure sufficiently smaller than the normal brake pressure.
- the timer is set to the predetermined time (TM1)
- step 106 the standby pressure PB1 is commanded and it is determined whether the elapsed time of force (T1) exceeds the predetermined time (TM1). It is judged.
- it is necessary to count the time for the predetermined time TM1 because the hydraulic oil to the hydraulic servo of the first brake B-1 is filled and the first brake B-1 is activated, and the intermediate rotating member It is to wait for the 18 rotations to be stopped.
- the process proceeds to step 108 and the standby pressure PB1 is set. A command to sweep down at a predetermined inclination is issued.
- the standby pressure PB1 applied to the brake B-1 is gradually lowered at a predetermined gradient as shown in FIG.
- step 110 it is determined whether or not the intermediate rotating member (rotating drum) 18 is rotating by taking in the signal of the intermediate rotation detecting sensor 33. If YES (judged that it is rotating), the process proceeds to step 112 to output a command to gradually increase the standby pressure PB1 that has been swept down, and then, at step 114, the intermediate rotating member (rotating drum It is determined whether or not 18 rotations have stopped. If the result of the determination in step 114 is YES (determined as being stopped), the increase in the waiting pressure PB1 is stopped in step 116, and the pressure at the time when the rotation of the intermediate rotary member (rotary drum) 18 is stopped is maintained. A command to hold (hold at a constant pressure) is output.
- step 110 determines whether it is rotating or not rotating. If the determination result in step 110 is NO (judged that it is not rotating), the process returns to step 108 to continue the sweep down process, and the determination result in step 114 is NO. In the case of (determining that the engine has stopped), the process returns to step 112 and continues the process of increasing the waiting pressure PB1 until the rotation of the clutch C3 is stopped. Therefore, by sweeping down the working pressure of the first brake B-1 in step 108 until the intermediate rotating member 18 rotates, and sweeping up the intermediate rotating member 18 in step 116 until the intermediate rotating member 18 rotates.
- the hydraulic pressure of the first brake B-1 can be set to the minimum necessary hydraulic pressure that can stop the rotation of the intermediate rotation member 18.
- a reverse range (R) is determined in step 120. That is, when the reverse range (R) is determined based on the signal from the range position sensor 34 in step 120, the standby pressure is controlled to 0 in step 122, and then in step 124, the second brake B is 2) A control command necessary for forming a reverse is output, and the second brake B-2 is engaged with a predetermined brake pressure. In this case, the rotation of clutch C 3 due to drag torque is stopped. Because of this, one of the frictional engagement elements of the brake B-2 can be engaged with the other frictional engagement element in a stopped state. Therefore, since no rotational change of the rotating elements in the planetary gear set 21 occurs, no shock occurs when the brake is engaged, and the output torque Tout does not change.
- step 126 the timer is set to a predetermined time (TM2), and in step 128, the reverse is performed.
- a control command necessary for formation is output, and it is determined whether or not the force elapsed time (T2) exceeds a predetermined time (TM2). If the elapsed time (T2) exceeds the predetermined time (TM2) and the determination result is YES, the process proceeds to step 130, where the third clutch C-3 is given a predetermined control command necessary for clutch engagement. . As a result, the clutch C3 is engaged while being operated with a gentle gradient that does not generate an engagement shock.
- step 128 by waiting for the predetermined time TM2, simultaneous engagement of the second brake B-2 and the third clutch C-3 can be prevented, and shift shock due to simultaneous engagement can be prevented. .
- the engagement of the brake B-2 and the clutch C-3 forms a reverse (step 132) and the program returns.
- the reverse command when the reverse command is issued, the drain command of the hydraulic fluid of the first brake B-1 and the hydraulic fluid supply command of the second brake B-2 are simultaneously performed.
- the hydraulic servo of the second brake B-2 is filled with hydraulic oil immediately will be filled with hydraulic oil late with respect to the no command. Therefore, during this delay, the hydraulic fluid of the first brake B-1 is drained first, so no tie-up actually occurs.
- the first brake B-1 is actuated at the time of neutral position
- the force is also made to stop the rotation of the intermediate rotating member 18 due to the drag torque at the minimum necessary brake pressure (standby pressure PB1), when the reverse command is received by the rotation of the shift lever.
- the time required for draining the operating pressure of the first brake B-1 which is supplied to stop the rotation of the intermediate rotating member 18 and which is unnecessary for forming the reverse can be minimized.
- the second brake B-2 that engages the second brake B-2 can be quickly engaged without the need to delay the engagement of the second brake B-2 forming the reverse. It will be possible to match.
- the rotation of the intermediate rotating member 18 constituting the rotating drums of the third and fourth clutches C-3 and C-4 is detected by the intermediate rotation detecting sensor 33, and ⁇
- the brake B-1 is blocked in neutral and the rotation of the intermediate rotating member (rotation drum) 18 is prevented at the time of neutral If the brake is operated at a sufficient brake pressure (standby pressure PB1), it is possible to prevent the rotation of the clutch due to the bowing I shear torque in the neutral state by open loop control.
- the present invention is not limited to such an embodiment. Instead, it can be applied to a wide range of automatic transmissions that supply lubricating oil to other clutches via one clutch.
- the automatic transmission according to the present invention is used in an automatic transmission that shifts and outputs the rotation of an automobile engine to multiple stages by engaging and disengaging a plurality of frictional engagement elements consisting of a clutch and a brake. Is suitable.
