摘要： PROBLEM TO BE SOLVED: To prevent the lowering of a release side hydraulic pressure in engagement shifting between frictional engagement elements of an automatic transmission. SOLUTION: A release valve 24 for changing over a feed passage of the hydraulic pressure to a control valve is disposed in an upstream of the oil passage of the control valve 25 for controlling the hydraulic pressure of a first frictional engagement element B-3, the hydraulic pressure from a first oil passage 201e capable of feeding hydraulic pressure in attaining a first speed gear stage via the release valve and a second oil passage 201b capable of feeding the hydraulic pressure in attaining the first and the second speed gear stage is made to possible via the release valve, and only when shifting from the first speed gear stage to the second speed gear stage, the feeding of the hydraulic pressure to the control valve 25 is changed over the second oil passage 201b. This constitution can eliminate changeover of the feed oil passage to the control valve 25 in shifting from the first speed gear stage to the second speed gear stage so a to prevent the lowering of the hydraulic pressure in releasing the first frictional engagement element B-3 with the hydraulic pressure of a second frictional engagement element B-2 set to an original pressure.

摘要： PURPOSE:To form a control device in a compact state by a method wherein by applying the oil pressure of a second frictional engagement element, a plunger is brought into contact with a spool and a control valve interlocking with the spool is located in the oil pressure feed and discharge oil passage of a first frictional engagement element. CONSTITUTION:Since a spool 251 is governed in such a state that an external control signal pressure is exerted on a plunger 252, a control valve 25 controls the oil pressure of a first frictional engagement element B-3 by means of an external control signal pressure, the oil pressure of a second frictional engagement element B-2, and a feedback oil pressure from a first frictional engagement element. Further, during other gear shift, since the oil pressure of the second frictional engagement element B-2 is not fed to the plunger 252, the plunger 252 is separated away from the spool 251. The spool 251 controls the oil pressure of the first frictional engagement element B-3 by means of the an external control signal pressure and the feedback pressure of the first frictional engagement element B-3. Thus, since a force exerted on the control valve 25 during grasp switching gear shift is ensured by increasing a pressure receiving area, a device can be formed in a compact manners.

摘要： PURPOSE: To prevent simultaneously supplying an oil pressure at speed change time of regripping a friction engaging element of an automatic transmission and to prevent pressure dropping and engaging delay at high speed shift starting time. CONSTITUTION: A relay valve 26 is provided between a control valve 25 and the first friction engaging element B-3, to ensure a drain by an engaging pressure of the second friction engaging element B-2, so as to prevent simultaneously supplying an oil pressure to both the friction engaging elements at speed change time of regripping by failure of the control valve 25. Release valve 24 of switching supply of oil pressure to the valve is arranged in the oil path upstream of the control valve 25, and oil pressure supply to the control valve 25 is interrupted at high speed shift (3-speed shift) starting time, to eliminate a useless flow loss by pressure governing operation. At regripping speed change time, an oil pressure is supplied from a shift valve 21 not switching operated to the control valve 25 by making a detour around a shift valve 22 switching operated, to prevent decreasing a release pressure at regripping time.

摘要： PROBLEM TO BE SOLVED: To make the function for restraining the external disturbance of a solenoid compatible with the function for increasing a follow property by providing a moderate means for moderating a target current value, in a thing by which the solenoid arranged in the oil pressure control circuit of a vehicular automatic transmission is feedback-controlled. SOLUTION: A transistor 49 in the drive control circuit of a solenoid 100 provides a switching function for impressing a battery voltage to a coil 39 only when a duty signal is turned on and a moderating circuit 52 for inputting a target current value in response to the engaging oil pressure of a friction engaging device and a vehicle state. Here, the target current value is moderated based on the vehicle state. The signal of the real current value of the solenoid 100 detected by a current detection circuit 51 is compared with the signal of the moderated target current value at an adding point 53 and a deviation is extracted. This deviation is outputted as a duty signal to the transistor 49 via PID controller 54 and feedback-controlled.

摘要： PROBLEM TO BE SOLVED: To make it difficult to vibrate, also to previously set control gain that has high responsiveness in the range and to prevent the occurrence of vibration by providing a means which changes the control gain of feedback in accordance with control condition. SOLUTION: First, control conditions such as throttle opening, oil temperature and kinds of speed changes are read (step 1). Next, control gains such as proportion gain, integration gain and differentiation gain are selected and adopted in accordance with the control conditions (step 2). The feedback control of each linear solenoid valve is executed based on an expression, including the value of each adopted control gain (step 3). In the expression, KP represents proportion gain, K1 represents integration gain, KD represents differentiation gain and (e) represents deviation. Therefore, the coupled vibration of a feedback control system and a hydraulic pressure system is prevented beforehand.
