PROBLEM TO BE SOLVED: To gradually increase a hydraulic pressure of an engine clutch around a previous torque transmission start point in the state that a constant relative speed is maintained between an engine and a motor under an unloaded condition, and detect a torque change of the engine and the motor, or a speed change of the motor for learning control of a torque transmission start point of the engine clutch.SOLUTION: A torque transmission start point learning control method includes a step for determining whether or not power transmission of a transmission for transmitting output of an engine and a motor is intercepted, a step for determining whether or not the engine is activated, a step for controlling the motor so that a speed of the motor is maintained at a prescribed speed different from a rotational speed of the engine in the state that power transmission of the transmission is intercepted and the engine is activated, a step for detecting a state change of the motor while increasing an applied hydraulic pressure of an engine clutch at a prescribed ratio, and a step for calculating a torque transmission start point of the engine clutch on the basis of the state change of the motor. |
