ABSTRACT:
A power transmission control device for vehicle controls switching between a speed increasing mode and a constant speed mode on the basis of electrical load, battery or the like, and shock due to switching is less. The power transmission control device includes: an electric rotating machine5; a crank pulley15; a planetary gear mechanism consisting of a sun gear18, a planetary gear19and an internal gear20; and controller70for controlling an electromagnetic clutch21. The electromagnetic clutch21is ON to operate the planetary gear mechanism as a speed increasing mechanism and drive the electric rotating machine5at an increasing speed, when engine speed of the internal combustion engine1is not higher than a predetermined value, remaining capacity of the battery9is not more than a predetermined level or electrical load is in a high-load state.
