PROBLEM TO BE SOLVED: To stabilize output shaft torque and reduce shift shock by using a value which is lowered than an indicated value just before a feedback control is started by prescribed amount as an initial value at a point of time when the feedback control is started. SOLUTION: A torque phase control is performed before a feedback control is started, subsequently input/output shaft relative revolving speed NDEF is started to be lowered, an inertia phase is started and a feedback control is performed for a clutch pressure indicated value SCDUF based on input/output shaft relative revolving speed NDEF after this detection. At this stage, a value which is lowered than an indicated value SCDUH just before a feedback control is started by prescribed amountαis imparted as an initial value of the feedback control. As for the setting of prescribed amountα, a value which is preliminarily obtained by an experiment so that input/output shaft relative revolving speed NDEF may be stably lowered by the feedback control is imparted by a map according to an operating state. Thus, shift shock due to delay in a response of shaft pressure or a too high indicated value itself can be reduced. |
