摘要： A controller for automatic transmission that performs feedback control on a slip ratio of a lockup clutch is adapted to select one target slip ratio from a plurality of target slip ratios based on a detected automatic transmission fluid temperature of a torque converter. Thus, the controller can ensure good followability to a target value of the feedback control even when the automatic transmission fluid temperature is low. The controller can effectively prevent engine hunting and the associated vibrations of vehicle body. Therefore, the controller can accomplish a favorable slip control of the lockup clutch even if an operating range of the lockup clutch is expanded to a range where the automatic transmission fluid temperature is low.

摘要： When switching to a forward running is made while a vehicle is running in a reverse direction, a switching to the forward running condition is made at an early time to thereby prevent the deterioration of the durability of the hydraulic engaging element due to slipping. For that purpose, when a vehicle speed (V) has exceeded a predetermined value (YVa) in a reverse range (R) and also when the vehicle speed (V) has never fallen below the predetermined value (YVa) in a neutral range (N), a reverse signal (FREV=1) is outputted. If FREV=1 at the time of switching to the forward range, the relationship between the vehicle speed and the speed stage (speed change map) is set to one (a reverse-running-measure speed change map) which is different from that at an ordinary time, to thereby determine the speed stage to be established. Then, a low speed stage is established even at a relatively high vehicle speed. Switching is thus made at an early time to the forward running condition with a large torque to be transmitted via the low speed stage.

摘要： At downshifting, hydraulic pressure of hydraulic clutch on engaging side (ON clutch pressure) is increased when an input and output speed ratio ("Gratio") has fallen below a predetermined value YGDNS. YGDNS is variably set depending on the vehicle speed and the engine temperature so that it becomes a lower value at a high vehicle speed than at a low vehicle speed, and a higher value at a low engine temperature than at a high temperature. When a downshifting command to a still lower speed stage is issued during downshifting control (when FTBD=1), a downshifting completion processing is performed in the course of the downshifting control (step in S111). Oil pressure in a hydraulic engaging element on the disengaging side QDNOFF and oil pressure in a hydraulic engaging element on the engaging side QDNON are switched to the oil pressures at the time of completion of downshifting, to thereby complete the first step downshifting control at an early time. In order to prevent unnecessary speed changing at the time of tire locking, downshifting is prohibited when deceleration of the vehicle speed has exceeded a predetermined value (when a setting of FLOCK=1 is made).
摘要翻译： 当降档时，当输入和输出转速比（“Gratio”）已经下降到预定值YGDNS以下时，接合侧液压离合器的液压（ON离合器压力）增加。 YGDNS根据车速和发动机温度可变地设定，使得它在高车速下比在低车速下变低，在低发动机温度下比在高温下更高。 当在降档控制期间（当FTBD = 1时）发出向较低速度级的降档指令时，在降档控制的过程中执行降档完成处理（步骤S111）。 分离侧的液压接合元件中的油压QDNOFF和接合侧的液压接合元件QDNON中的油压在切换完成时切换到油压，从而在早期完成第一级降档控制 时间。 为了防止在轮胎锁定时不必要的速度变化，当车速的减速超过预定值时（当设定为FLOCK = 1时），禁止降档。

摘要： Even if a rotational speed of an engine has already increased due to slipping of a fluid torque converter at the time of start of downshifting, a smooth downshifting is performed. For that purpose, there is obtained a speed change developing degree function K(etrm) of the rotational speed of the engine at the time of start of downshifting, the developing degree being dependent on an increase in the rotational speed of the engine due to slipping in the fluid torque converter. The function K(etrm) is obtained with a speed ratio "etrm" of the fluid torque converter at the time of starting of downshifting as a parameter. A boosting correction value QDNOFFZ is computed by multiplying a reference correction value QDNOFFZO by K(etrm) (step S108-5). The hydraulic pressure of the hydraulic engaging element on the disengaging side during downshifting is boosted by the amount of QDNOFFZ (step S108-6).

摘要： A control system for a hydraulically-operated transmission for a vehicle is disclosed. The transmission is connected to a crankshaft of an internal combustion engine and having a plurality of friction engagement elements. A working oil temperature of the transmission, a cooling water temperature of the engine, and an operating condition of the transmission are detected. An estimated value of the working oil temperature is calculated on the basis of the detected cooling water temperature and the detected operating condition of the transmission. A weighting factor is calculated according to the detected working oil temperature. A weighted average value of the working oil temperature and the estimated working oil temperature is calculated as an actual working oil temperature by using the weighting factor. A hydraulic pressure of the working oil is controlled according to the actual working oil temperature.
