Abstract
A method for preventing takeoff of a motor velocity of a hybrid electric vehicle, may include checking whether an engine clutch is disengaged while an engine and a motor are simultaneously driven, checking whether a command of motor torque is zero when the engine clutch is disengaged, and checking whether the motor velocity is normal while the command of the motor torque is zero, wherein when the motor velocity abnormally increases as a result of checking whether the motor velocity is normal, the motor torque is corrected to be zero.
