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).
摘要翻译： 消除了通过启动电子控制电路在初始化操作期间建立高速级的常规传输中的缺点。 缺点是，由于在低速阶段运行时的初始化操作期间建立高速级，发动机的转速降低，结果是在完成后的驱动力的恢复 初始化操作被延迟。 为了解决这个缺点，提供了可以将变速器切换到行驶范围内的中立状态的阀。 在电子控制电路（20）的初始化操作期间，输出将变速器（1）换档到空档的空档信号（S902）。 如果变速器（1）处于运行范围，则在完成初始化操作之后进行齿轮控制，以根据当时的车速建立速度级（S908）。

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： 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.
摘要翻译： 当在车辆沿相反方向行驶时进行向前行驶切换时，早期切换到前进行驶状态，从而防止由于滑动导致的液压啮合元件的耐久性的劣化。 为此目的，当车速（V）在反向范围（R）中超过预定值（YVa）时，以及当车速（V）从未在中性值范围内下降到预定值（YVa）以下时 N），则输出反向信号（FREV = 1）。 如果在切换到正向范围时FREV = 1，则将车速与速度级（速度变化图）的关系设定为与后者的速度不同的一个（反向行驶速度变化图） 一般的时间，从而确定要建立的速度。 然后，即使在相对高的车速下也建立了低速级。 因此，在通过低速级传递大扭矩的情况下，在早期进行切换到正向运行状态。

摘要： A control system for an automatic transmission of a vehicle is disclosed. The automatic transmission operates in a manual operating mode in which a shift position of the automatic transmission can be changed according to a shift instruction issued by a driver of the vehicle, or in an automatic operating mode in which the shift position is automatically selected. In the control system, a slow running intention of the driver is detected. A first shift position is set to a starting shift position at the time of starting the vehicle when the slow running intention of the driver is not detected in the manual operating mode. A second shift position which is lower in transmission gear ratio than the first shift position is set to the starting shift position when the slow running intention of the driver is detected in the manual operating mode.

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： In a control apparatus for a hydraulically operated vehicular transmission having a plurality of speed stages to be established by a selecting operation of a plurality of hydraulic clutches, when a command to downshift to G(N-2) is issued in the course of downshifting to G(N-1) and a flag FTBD is set to 1, a control is performed to accelerate the time of completion of the downshifting control to G(N-1). When that oil temperature in the transmission which is detected by an oil temperature sensor is lower than a predetermined value, the setting of FTBD to 1 is prohibited. Therefore, at the time of low oil temperature, the downshifting to G(N-1) is performed in an ordinary manner. At the time of starting of the downshifting control from G(N-1) to G(N-2), the hydraulic pressure in the hydraulic clutch for the speed stage G(N-1) is sufficiently increased. A smooth downshifting to G(N-2) can thus be smoothly performed without the occurrence of excessive engine racing.
