    • PROBLEM TO BE SOLVED: To favorably suppress the generation of a shock caused by abrupt engagement resulting from a delay of an engagement start of an engagement-side friction engagement element when a speed change stage is up-shifted in an acceleration on condition.SOLUTION: When the speed change stage is up-shifted in the acceleration on condition, there is performed engagement control including torque phase control after the execution of first fill control which controls a hydraulic control unit so that a hydraulic fluid is filled into a hydraulic servo of the engagement-side friction engagement element such as a clutch C3, and standby control which controls a hydraulic control unit so that the hydraulic pressure of the engagement-side friction to the hydraulic servo may be held at preset standby pressure, When there is inspected a variation of a rotation acceleration speed dNi of an input shaft 26 which exceeds a degree based on thresholds dNi1, ddNire and dNi3 which are preset as determination references after the most-recent standby control, a first fill time is corrected to an increase side (steps S240 to S300).
    • 解决问题:为了有利地抑制当在加速度条件下变速阶段被上变换时由于接合侧摩擦接合元件的接合开始的延迟引起的突然接合产生的冲击的产生 。 解决方案:当变速阶段在加速状态下上变换时,执行包括扭矩相位控制在内的接合控制,第一填充控制执行后控制液压控制单元,使液压油被填充 诸如离合器C3的接合侧摩擦接合元件的液压伺服机构以及控制液压控制单元的待机控制,使得与液压伺服机构的接合侧摩擦力的液压可以保持在预设待机压力下 检查输入轴26的旋转加速度dNi的变化,其超过基于在最近的待机控制之后作为确定基准预设的阈值dNi1,ddNire和dNi3的程度,将第一填充时间校正为 增加侧(步骤S240〜S300)。 版权所有(C)2012,JPO&INPIT
