<P>PROBLEM TO BE SOLVED: To provide a control device of a vehicle power transmission mechanism, capable of improving drivability by taking overlapping of a change in engine rotational speed, and change and fluctuation in target engine rotational speed corresponding to the speed change characteristics into consideration, and performing coordinated control without a shock or an engine stall by taking timing of lock-up release and fuel cut restoration at deceleration of a vehicle into consideration. <P>SOLUTION: The control device (3) provided with a first map (M1) capable of performing coast down control of altering a transmission ratio of a continuously variable transmission (5) at deceleration of the vehicle has a second map (M2) which is set by making a lock-up release vehicle speed for releasing a lock-up clutch (6) and an engine rotational speed corresponding to each other, in which, when coast down control is performed, the second map (M2) is used to set a lock-up release vehicle speed for releasing the lock-up clutch (6). <P>COPYRIGHT: (C)2012,JPO&INPIT |
