<P>PROBLEM TO BE SOLVED: To improve response properties by reducing the time required for switching connection of a rotary electric machine to an input shaft or an output shaft of a transmission. <P>SOLUTION: A control device for a power transmission mechanism includes an engine, a rotary electric machine, a transmission mechanism, and a switching control means. The transmission mechanism changes a gear ratio being a ratio between rotation speeds of an input shaft and an output shaft connected to a wheel. The switching control means switches connection of the rotary electric machine to either the input shaft or the output shaft of the transmission mechanism after synchronizing rotation with the rotary electric machine, wherein the switching control means performs the rotation synchronization after causing the rotary electric machine to be in a neutral state while causing the rotary electric machine to generate torque so that a rotation change direction of the rotary electric machine is in the rotation change direction when performing the rotation synchronization, and switches the connection of the rotary electric machine. <P>COPYRIGHT: (C)2013,JPO&INPIT |
