Abstract
A control device for a lock-up-clutch installed in a torque converter arranged between an engine and an automatic transmission mechanism includes an engagement control means that carries out a calculation to increase an engaging capacity of the lock-up-clutch with the passage of time during an engagement control time in which the torque converter is shifted from a converter condition to a lock-up condition in which the prime mover drives an auxiliary device and in which when, during the control to increase the engaging capacity of the lock-up-clutch, an input torque to the torque converter from the engine is increased due to reduction in load of the auxiliary device, the engagement control means promotes the increase of the engaging capacity of the lock-up-clutch based on the amount of increase of the input torque thereby eliminating undesired pressure shortage that would be induced in the period toward the lock-up condition.
