    • A spool of a lock-up control valve has a first effective area exposed to a release pressure which is supplied to a release chamber of the lock-up clutch and a second larger effective area which is exposed to the apply pressure which is supplied to an apply chamber. When acceleration is demanded when the lock-up clutch is in one of slip or fully lock-up modes and a sudden demand for acceleration is made, the pressure differential between the apply and release pressures is reduced below the normal level for a predetermined period of time.
    • 锁定控制阀的阀芯具有暴露于释放压力的第一有效区域,该有效区域被供应到锁止离合器的释放室,并且暴露于施加压力的第二较大有效区域,该有效区域被供应到 应用室。 当锁止离合器处于滑动或完全锁定模式之一并且急剧加速的需求时需要加速时,施加和释放压力之间的压力差降低到正常水平以下一段预定时间 时间。
