Control of electric rotating machine in hybrid-type power transmission

摘要

A hybrid-type power transmission in which an internal combustion engine (14) and an electric rotating machine (13) are used as a source of power for driving an output shaft (11) through a change-speed mechanism (30). In the hybrid power transmission, the operation of the electric rotating machine (13) is controlled in such a manner that the rotation speed of a rotor-side rotary member (21) is synchronized with the rotation speed of an input-side or output-side rotary member (24 or 25) when the rotation speed of the rotor-side rotary member (21) becomes higher in a predetermined difference (–³o) than the rotation speed of the input-side or output-side rotary member (24 or 25) in shifting operation of a sleeve (26) coupled with the rotor-side rotary member (21).
