    • A control device of a power transmission device includes a damper absorbing torsional vibration between a fluid transmission device with a lockup clutch and an engine, the power transmission device is disposed with a connecting/disconnecting device capable of connecting and interrupting power transmission on the downstream side of the fluid transmission device, the control device has a lockup engagement control means engaging the lockup clutch while the power transmission is interrupted by the connecting/disconnecting device in a predetermined engine rotation speed range lower than an idle rotation speed when the engine is started, the lockup engagement control means includes: a resonance due to frequency entrainment determination means determining whether a resonance due to frequency entrainment occurs that blocks an increase in an engine rotation speed NE depending on whether a predefined resonance determination time is exceeded by a required start time of the engine or an elapsed time until the engine rotation speed NE reaches a predetermined rotation speed; a lockup engagement means engaging the lockup clutch while the power transmission is interrupted by the connecting/disconnecting device when the resonance due to frequency entrainment determination means determines that the resonance due to frequency entrainment occurs.
    • 动力传递装置的控制装置包括吸收具有锁止离合器的流体传动装置和发动机之间的扭转振动的阻尼器,该动力传递装置设置有能够连接和中断下游侧的动力传递的连接/断开装置 所述控制装置具有锁定接合控制装置,所述锁定接合控制装置与所述锁止离合器接合,同时当所述发动机起动时,所述动力传递在所述连接/断开装置中以比所述发动机起动时的空转速度低的预定发动机转速范围中断, 锁定接合控制装置包括:由于频率夹带确定装置确定是否发生由于频率夹带引起的谐振的共振,其根据预定的共振确定时间是否超过了所需的起始时间,阻止发动机转速NE的增加 引擎或经过的ti 直到发动机转速NE达到预定的转速; 当由于频率夹带确定装置引起的共振确定由于频率夹带引起的共振发生时,锁定接合装置接合锁止离合器,同时由连接/断开装置中断电力传输。
