Abstract
A control system is proposed that electro-hydraulically develops a servo actuating fluid pressure that momentarily drops to prevent an increase in frictional transmission torque of a friction element which otherwise would be caused by an increase in dynamic frictional coefficient between a driving and a driven member of the friction element as the relative rotation of them decreases toward zero.
