Claim:
1. A launch control method for a vehicle with a dry-type clutch, comprising: determining, by a controller, a target engine speed corresponding to an operation amount of an accelerator pedal of the vehicle when vehicle launch is started by operation of the accelerator pedal; calculating, by the controller, a feedforward component which is part of the torque to control the clutch using a rate of change over time of the target engine speed and a current engine torque; calculating, by the controller, a feedback component which is part of the torque to control the clutch based on a difference between the target engine speed and the current engine speed; calculating, by the controller, a compensation torque using a current engine torque and an estimated clutch torque which is estimated to be currently transferred by the clutch; and controlling, by the controller, a clutch actuator to drive the clutch with a sum of the feedforward component, the feedback component, and the compensation torque.
