    • A control device controlling a vehicle's automatic transmission. The automatic transmission engages first and second friction engagement elements by fluid pressure from a pump operating using motive power from the vehicle's motor when a shift position is at a reverse traveling position, places the first friction engagement element on standby at a predetermined pressure that is higher than a stroke starting pressure by which a piston stroke is started and lower than a complete engagement pressure or engages the first friction engagement at the complete engagement pressure when the shift position is at a non-traveling position, and engages a third friction engagement element as a starting shift speed when the shift position is at a forward traveling position. When the shift position is at the forward traveling position, the first friction engagement element is placed on standby at the predetermined pressure if a vehicle speed is lower than a predetermined vehicle speed, or releases the predetermined standby pressure if the vehicle speed is equal to or higher than the predetermined vehicle speed.
    • 控制车辆的自动变速器的控制装置。 自动变速器通过来自使用来自车辆电动机的动力的泵的流体压力接合第一和第二摩擦接合元件,当变速位置处于相反的行进位置时,将第一摩擦接合元件置于待机状态,预定压力更高 比起动活塞行程开始并低于完全接合压力的行程起动压力或当变速位置处于非行驶位置时在完全接合压力下接合第一摩擦接合,并且将第三摩擦接合元件接合为 当换档位置处于前进行驶位置时的起动换档速度。 当换档位置处于向前行驶位置时,如果车速低于预定车速,则第一摩擦接合元件处于预定压力的待机状态,或者如果车速等于或等于则释放预定待机压力 高于预定车速。

    • A shift controller controls a downshift to a low shift speed, spaced apart from a high shift speed by two or more steps, through an intermediate shift speed, by first releasing first and second shift release elements, then engaging a first shift engagement element, and finally engaging a second shift engagement element, while controlling the torque capacity of the second shift release element by feedback control. As a result of releasing the first and second shift release elements before engaging the first shift engagement element, it is possible to rev up an input rotation at maximum performance of an engine to reduce the time for shifting. As a result of the feedback control of the torque capacity of the second shift release element after engaging the first shift engagement element, a torque fluctuation at the intermediate shift speed can be reduced to avoid occurrence of an uncomfortable shift shock.
    • 变速控制器通过首先释放第一和第二换档释放元件,然后接合第一换档接合元件,并将第一换档接合元件接合,并将第一换档释放元件与第一换挡接合元件接合, 最后接合第二换档接合元件,同时通过反馈控制来控制第二换档释放元件的扭矩容量。 由于在接合第一变速接合元件之前释放第一和第二变速释放元件的结果,可以在发动机的最高性能下加速输入旋转以减少换档时间。 由于第二换档释放元件在接合第一换挡接合元件之后的扭矩容量的反馈控制的结果,可以减小中间换档速度下的转矩波动,以避免发生不舒适的换档冲击。

    • A control system for an automatic transmission is provided with a manual shift mode capable of performing a shift command made by manual operation. While in the manual shift mode and during the operation of a downshift command generated by a shift lever, a manual shift control unit calculates a degree of power required by a driver that, for example, takes into consideration an operation intent of the driver and a road condition. A post-downshift shift speed is then determined in accordance with the degree of required power and downshifting performed. By performing only one downshift command through manual operation, downshifting in accordance with the degree of power required by the driver is performed. Downshifting to a shift speed desired by the driver can thus be promptly performed, without the operation becoming a burden.
    • 用于自动变速器的控制系统具有能够执行通过手动操作进行的换档指令的手动换挡模式。 在手动换挡模式下,在换挡杆产生的降挡指令的操作期间,手动变速控制单元计算驾驶员要求的功率,例如考虑驾驶员的操作意图和 道路状况。 然后根据所需功率和降档的程度来确定降档换档速度。 通过手动操作仅执行一个降档指令,执行根据驾驶员所需功率的降档。 因此可以迅速地执行降档到驾驶员期望的换档速度,而不会使操作变成负担。
