Abstract
An eco-friendly vehicle and a launch control method for an eco-friendly vehicle reduces an unpleasant secondary launch effect based on a gear alignment state of a transmission in a specific situation. The launch control method includes: determining a first condition for enabling a preset stop control when the first condition is satisfied; turning off a control for generating a creep torque of a motor when a brake is released; controlling a transmission in an open state and enabling the control for generating the creep torque; and when a second condition for revolutions per minute (RPM) of the motor is satisfied, controlling the transmission in a lock state through a slip state.
