摘要： There are prevented shocks that will occur when a switchover speed changing is made to transfer from one speed changing, in the midst of that speed changing, to another speed changing when the input and output speed ratio "Gratio", which serves a control parameter, is not accurately detected. For that purpose, there is used a flag FGFAIL for setting "1" when the input and output speed ratio "Gratio", at the time of non-speed changing, does not lie within a predetermined range based on the gear ratio of the speed stage that is being established at that time. A switchover speed changing in which switching to another speed changing is made during a speed changing is prohibited when FGFAIL=1.

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： The disadvantage in the conventional transmission in which a high speed stage is established during the initialization operation by the starting up of an electronic control circuit, is eliminated. The disadvantage is that the rotational speed of an engine lowers due to the establishment of the high speed stage during the initialization operation at the time of running in a low speed stage, with the result that the recovery of the driving force after the completion of the initialization operation is delayed. To solve this disadvantage, valves that can switch the transmission to a neutral condition in the running range are provided. During the initialization operation of the electronic control circuit (20), a neutral signal which shifts the transmission (1) to the neutral condition is output (S902) to the valves. If the transmission (1) is in a running range, there is performed an in-gear control, after the completion of the initialization operation, to establish a speed stage depending on the vehicle speed at that time (S908).

摘要： Upshifting is performed in a short time without giving rise to shocks. For that purpose, at the time of upshifting, a hydraulic pressure (QUPOFF) of a hydraulic engaging element on disengaging side is controlled such that the input and output speed ratio ("Gratio") of a transmission is decreased to, and held at, a predetermined slipping region (YG(N)S) that is lower than an engaging region (YG(N)L)-YG(N)H) to be set based on a gear ratio which is established by the engagement of the hydraulic engaging element on the disengaging side. The hydraulic pressure (QUPON) of a hydraulic engaging element on engaging side is gradually increased. When "Gratio" once falls below YG(N)L and then increases up again to YGCONOK, QUPOFF is lowered to a predetermined low pressure (QUPOFFB) at a lapse of a predetermined time (YTMUP8). Once "Gratio">YGCONOK, QUPON is increased to a predetermined high pressure QUPONB at a lapse of a second predetermined time YTMUP3. YTMUP8 is set so as to become shorter with an increase in a vehicle speed, and YTMUP3 is set so as to become longer with an increase in the vehicle speed.

摘要： Shift valves 141, 142, 143 are provided to switch oil passage connections to a state in which an oil pressure in one hydraulic clutch of an arbitrary speed transmission train and an oil pressure in a hydraulic clutch of a transmission train which is adjacent thereto as seen in the order of speed are controllable by a pair of linear solenoid valves 201, 202. Skipped speed change from a predetermined first speed transmission train to a second speed transmission train which is not adjacent to the first speed transmission train is made possible. In concrete, a large-capacity accumulator A5 is connected to an oil passage L19 which is in communication with 5th-speed hydraulic clutch C5. At the time of skipped speed changing from 5th speed to 3rd speed, shift valves 141, 142, 143 are switched to a state of 3rd-4th speed change. The oil pressures in the hydraulic clutches C3, C4 for 3rd and 4th speed transmission trains, respectively, are made controllable by the linear solenoid valves 201, 202. While buffering the pressure decrease of the oil pressure in the 5th-speed hydraulic clutch C5 by the accumulator A5, pressure increase control of 3rd-speed clutch C3 is carried out by one of the linear solenoid valves to thereby skip-downshift from 5th to 3rd speed. The other linear solenoid valve is held at a low-pressure waiting state to prepare itself for the 3rd-4th speed switch-upshifting.

摘要： A control system of a lockup clutch of a torque converter of a vehicle automatic transmission. A basic manipulated variable is determined in response to the vehicle operating condition in accordance with a predetermined characteristic, and the lockup clutch engaging force is controlled in response to the variable. In the system, fuzzy reasoning is carried out using the detected vehicle operating parameters to correct the basic manipulated variable, and the engaging force is controlled in response to the corrected manipulated variable, when the control condition is met. The corrected manipulated variable is gradually decreased with respect to time when the vehicle driving state has shifted from a region in which the engaging force is controlled in response to the corrected manipulated variable to a region in which the lockup clutch is disengaged. In addition, the corrected manipulated variable is gradually increased when the vehicle driving state has shifted from a region in which the lockup clutch is disengaged to a region in which the engaging force is controlled in response to the corrected manipulated variable.

摘要： A system for controlling a vehicle automatic transmission, in which a gear ratio to be shifted to is determined based on the vehicle speed and throttle opening degree and a clutch is supplied with hydraulic pressure such that the rotational speed of the transmission input shaft concurs with a desired rotational speed change rate. The system includes means for discriminating whether the engine load fluctuates and the operation is discontinued when it is discriminated that the engine load fluctuates. Specifically, even when the accelerator pedal is operated only somewhat rapidly and the engine output is able to follow the change in the degree of throttle opening, the degree of throttle opening nevertheless differs between that at the start of gearshift and that in the course of gearshift thereafter, causing unexpected gearshift shock to occur. The arrangement can solve the problem.
