    • A control device of a transmission fluid pressure for an electronically controlled automatic transmission comprising: a rotational number change detecting means for detecting a rotational number change of either an engine or a rotational member of an automatic transmission; a transmission fluid pressure controlling means for arbitrarily controlling a transmission fluid pressure for a transmission fluid pressure controlling device of the automatic transmission; and a control device for controlling a target value of the transmission fluid pressure for the transmission fluid pressure controlling device by a negative feed back control dependent at least on the rotational number change of either the engine or the rotational member of the automatic transmission, said control device determining whether the engine is in a constant speed or acceleration mode, and temporarily discontinuing the negative feed back control or reducing a control quantity thereof when the engine shifts from a deceleration/closed throttle mode to a constant speed or acceleration mode while the transmission fluid pressure controlling means is controlling the transmission fluid pressure for changing the gear in which the transmission to which the engine is coupled.
    • 一种用于电子控制的自动变速器的变速器液压的控制装置,包括:转速改变检测装置,用于检测自动变速器的发动机或旋转构件的转数变化; 用于任意地控制自动变速器的变速器油压控制装置的变速器油压的变速器油压控制机构; 以及控制装置,用于通过至少依赖于所述自动变速器的发动机或旋转构件的转数改变的负反馈控制来控制所述变速器油压控制装置的变速器油压的目标值,所述控制 确定发动机是否处于恒定速度或加速模式的装置,以及当发动机从减速/关闭节气门模式转换到恒定速度或加速模式时暂时停止负反馈控制或减少其控制量,同时传动液 压力控制装置控制变速器流体压力以改变其中与发动机连接的变速器的齿轮。
