<P>PROBLEM TO BE SOLVED: To provide a release control device capable of easily, accurately and further quickly determining the release of an electromagnetic engaging device. <P>SOLUTION: This release control device includes: a target rotating speed setting means for determining a target rotating speed of a predetermined rotation member after releasing the electromagnetic engaging device, while the electromagnetic engaging device is engaged when a release determination for switching the electromagnetic engaging device to a release state of cutting off the transmission of torque from an engaging state of being capable of transmitting the torque, is established; a feedback control means (Step S3) for controlling a rotating speed of the predetermined rotation member by making a feedback process based on a deviation between the target rotating speed and an actual rotating speed; and a release determining means (Step S6 and S7) for determining the release of the electromagnetic engaging device based on the fact that an indication torque value of a driving force source for rotating the predetermined rotation member, exceeds a predetermined reference value when releasing by reducing electromagnetic force after the start of the feedback control of the rotating speed of the predetermined rotation member by the feedback control means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
