POWER TRANSMISSION CONTROL DEVICE FOR VEHICLE

A manual transmission of the present apparatus has an EV travel gear position (the 1-st gear) for EV travel performed through use of only drive torque of a motor connected to the output shaft of the transmission, and EG travel gear positions (the 2-nd gear to the 5-th gear) for traveling through use of drive torque of an engine transmitted via a clutch. In the case where the EV travel gear position (the "1-st gear") is selected, after a clutch pedal is depressed in a state in which the vehicle is stopped, and an accelerator pedal is not operated, "creep vehicle speed control" utilizing MG torque is executed. The "creep vehicle speed control" enables a driver to adjust a very small vehicle speed by adjusting the clutch return stroke without operating the accelerator pedal. Thus, it becomes possible to provide a power transmission control apparatus for an HV-MT vehicle which allows EV travel, and can realize travel at very slow speed, similar to so-called creeping.
