<P>PROBLEM TO BE SOLVED: To provide a control method for attaining normal operating property as much as possible, even if any one of first or second clutches connected to first and second intermediate shafts and a plurality of transmission clutches becomes unreleasable, by transmitting the power of an engine via the other clutch. <P>SOLUTION: When the first clutch 16 becomes unreleasable, a generator motor 29 is energized as a generator in a vehicle stop state in which the second clutch 17 is in a neutral position, and the fourth clutch 24 is shifted to a second shift gear stage 20. According to this, an engine torque is transmitted from a differential device 25 to a second intermediate shaft 15 to develop a driving force in an output shaft 18 through the second shift gear stage 20 to allow start (second stage start-up). Thus, an alternate control method for the case in which one of the plurality of clutches becomes unreleasable is prepared, whereby a highly reliable drive system without stop can be obtained. <P>COPYRIGHT: (C)2010,JPO&INPIT |
