<P>PROBLEM TO BE SOLVED: To provide a gear change control device of a vehicle for achieving both the shortening of a gear change time and the suppression of driving force fluctuation. <P>SOLUTION: This gear change control device of a vehicle is provided with an inertia phase startability determination part 400a for determining whether or not the inertial phase of a gear change is startable after the down-shift conditions of an automatic transmission AT are established when a vehicle decelerates; and a gear change promotion control part 400b for inputting gear change promotion torque to the input side of the automatic transmission AT by driving a motor generator MG when it is determined that the inertial phase is startable. <P>COPYRIGHT: (C)2009,JPO&INPIT |
