Abstract
PURPOSE:To avoid deterioration of operability by putting a lock-up mechanism into a non-operating state under control of lock-up control means by look-up prohibit means on detecting that the operating oil quantity is less than a designated value. CONSTITUTION:Lock-up control means is adapted to supply and discharge operating oil to a lock-up mechanism to put input and output shafts of a torque converter in the direct-coupled state according to the load state of an engine or the running state of a vehicle. When oil quantity detecting means detects the state that the quantity of operating oil is decreased and air gets mixed in operating oil supplied to the lock-up mechanism, according to the signal, lock-up prohibit means outputs a signal for prohibiting the operating state of the look-up mechanism. Thus, deterioration of operability of the vehicle caused by delay in operation of the lock-up mechanism or release operation can be avoided effectively.
