Abstract
A vehicular power transmission control apparatus including: a multiple gear ratio transmission including an input shaft receiving power from an engine output shaft and an output shaft outputting power to drive wheels of a vehicle, a clutch mounted between the output shaft of the engine and the input shaft of the transmission, and a control unit controlling a clutch torque and a gear position of the transmission based upon a vehicle driving condition, wherein the control unit controlling the clutch torque such that a revolution speed of the transmission input shaft becomes smaller than a revolution speed of the engine output shaft by a predetermined positive value in a semi-engagement state with a slip, when the vehicle drives with the transmission gear position set to a low speed range including a first gear and a second gear.
