The invention discloses a traction-controlled vehicle working condition identification method and system and a vehicle, which are characterized in that the wheel speed difference and the vehicle speed are judged to identify that the current vehicle is in a curve working condition, and the maximum braking force difference and the vehicle speed are judged to identify that the current vehicle is in a split working condition; according to the method, the driving gradient and the vehicle speed are judged to recognize that the vehicle is in the ramp working condition at present, and the current longitudinal friction coefficient potential, the longitudinal friction coefficient and the lateral friction coefficient are judged to recognize the friction coefficient utilization state, so that the necessary working conditions in the traction control system are recognized; when the working conditions are met, judgment is carried out in time, and it is guaranteed that a corresponding control mode is carried out subsequently.
