Method of controlling launch of vehicle

A method of controlling launch of a vehicle, comprising:

• a setting step in which a controller sets a predetermined target engine speed of an engine according to an operation amount of an accelerator pedal;
• a transient control step in which the controller feedback-controls a clutch torque based on the predetermined target engine speed and an engine speed to be measured;
• a transient state determining step in which the controller determines, during performing of the transient control step, when a transition period of change of the engine speed elapsed based on whether an engine speed change amount is less than a predetermined reference engine speed;
• a first correction amount determination step in which when it is determined as a result of performing the transient state determining step that the transition period of change of the engine speed elapsed, the controller determines a correction amount by using a difference between a measured engine speed input and the basic target engine speed;
• a second correction amount determination step in which a previous correction amount is multiplied by a forgetting factor determined by reflecting the vehicle speed change amount;
• a correction applying step in which the controller adds the correction amount to the predetermined target engine speed and then determines a final target engine speed;
• an error determination step in which the controller determines an engine speed control error by using a difference between the final target engine speed and a measured engine speed;
• and
• a feedback determination step in which the controller uses the engine speed control error and determines a feedback control amount for feedback-controlling a clutch actuator,
• wherein the controller performs steps from the correction applying step to the feedback determination step repeatedly until the launch of the vehicle is completed and wherein the correction amount required for the correction applying step uses, at a first time, the correction amount obtained by the first correction amount determination step and then, at a time of the repeated performing of the steps, a second correction amount obtained by the second correction amount determination step.
