The invention discloses a driver intention judgment system and method for vehicle drift control, and the system comprises a signal obtaining unit which is used for obtaining a wheel speed signal of each wheel, a current steering wheel angle signal, a current steering wheel angular velocity signal, a current accelerator pedal signal, a current brake pedal signal, and a current vehicle yaw velocity signal; the driver intention judging unit is used for judging the driving intention of a vehicle operator according to the wheel speed signal of the wheel, the current steering wheel angle signal, the current steering wheel angular velocity signal, the current accelerator pedal signal, the current brake pedal signal and the current vehicle yaw velocity signal, and generating a driving intention state signal; and the driver intention judgment unit is connected with the signal acquisition unit. According to the method, the vehicle control intention of the driver can be judged on the premise of not bringing extra operat
