<P>PROBLEM TO BE SOLVED: To prevent occurrence of impact noise and making engagement difficult when a rotary electric machine is changed over and connected to a power transmission in a hybrid-type power device. <P>SOLUTION: The hybrid-type power device includes: a transmission 30 having an input shaft 10 and an output shaft 11; an internal combustion engine 14 for driving the input shaft; and a rotary electric machine 13 selectively coupled with the input shaft or the output shaft through a changeover mechanism 20. A rotary electric machine-side rotary member 21 of the changeover mechanism is selectively changed over and coupled with coaxially mounted input-side and output-side rotary members 24, 25, and coupled with the rotary electric machine, the input shaft, and the output shaft, respectively. Synchronization of the rotary electric machine-side rotary member with respect to the input-side and output-side rotary members is performed by controlling the rotation speed of the rotary electric machine so that the rotation speed Nm of the rotary electric machine-side rotary member becomes target rotation speed Ndi, Ndo faster than the rotation speed Ni, No of the input-side and output-side rotary members by respective predetermined differences Δi, Δo. <P>COPYRIGHT: (C)2010,JPO&INPIT |
