摘要： An automatic transmission controller has an electronic control circuit, an electromagnetic valve, and a pressure control valve. The electronic control circuit generates a control current. The electromagnetic valve regulates a command pressure in accordance with the control current. The pressure control valve has a spool and is formed with a spool hole. The spool reciprocates in the spool hole in accordance with the command pressure to regulate a pressure supplied to a friction element of an automatic transmission. In a standby state, when the friction element is in a disengaged state, the electronic control circuit generates an oscillating current as the control current so that the electromagnetic valve generates a standby command pressure that makes the spool reciprocate in a range in which no pressure is supplied to the friction element.

摘要： A hydraulic control system of a friction device where fail-safe is required is provided with one oil pressure switch and one pressure changeover valve. The pressure changeover valve is switched by auxiliary oil pressure based on an operation of the oil pressure control valve. When an auxiliary port communicates with an input port and the pressure changeover valve is switched to the filling determination side, the oil pressure switch is turned on and “filling determination” can be carried out. When the auxiliary port is disconnected from the input port, the pressure changeover valve is switched to the fail-safe determination side. The oil pressure switch is supplied with the same driving oil pressure as of the friction device and “fail-safe determination” can be carried out from the on/off state of the oil pressure switch.

摘要： A control method for an automatic transmission is capable of quickly determining whether gear shifting is permissive. The control method varies the command value input to an engaging-side electromagnetic valve that adjusts a hydraulic pressure applied to a frictional element to be engaged in a target gear in a specific time period, then determines a time variation in another time period of the hydraulic pressure applied to the frictional element that is adjusted by the engaging-side electromagnetic valve according to the input command value and detected by a detecting means. Determination of whether gear shifting is permissive or not on the basis of the time variation is thus determined.
