To provide a power transmission control device for an HV-MT car which can carry out EV driving.

In this device, when an EV travel gear position (EV, which corresponds to a first gear) is selected by a shift lever operation, a power transmission system is not established between an input shaft Ai and an output shaft Ao of a manual transmission M/T but a power transmission system is established between an output shaft Am of a motor M/G and the output shaft Ao of the transmission M/T. As a result, EV travel is implemented by only the drive torque of the motor M/G connected to the output shaft Ao of the transmission M/T. Meanwhile, when EG travel gear position (second gear to fifth gear) is selected by the shift lever operation, a power transmission system is established between the input shaft Ai and the output shaft Ao of the manual transmission M/T. As a result, a vehicle travels by the drive torque of an engine E/G via a clutch C/T.
