Abstract
A launch control method of a vehicle includes: a clutch hold step of maintaining a clutch torque until an engine torque becomes smaller than the clutch torque, when a driver releases an accelerator pedal during launch control; a time constant determination step in which a time constant for a rate of releasing the clutch torque is determined depending on a difference between the clutch torque and a target creep torque when the engine torque becomes smaller than the clutch torque; a filter processing step of processing the time constant and the target creep torque using a low-pass filter that has the time constant and the target creep torque as an input and has a nominal clutch torque as an output; and a clutch control step of controlling a clutch using the nominal clutch torque.
