| description | The invention discloses a control method and system of a vehicle, and the vehicle. The control method comprises the steps: the difference value between the actual driving torque and the required torque of the vehicle is obtained to serve as the abnormal torque; a pre-stored abnormal torque safety critical curve is queried to obtain the allowable duration corresponding to the abnormal torque, and the abnormal torque safety critical curve is determined by the multiple pieces of abnormal torque and the multiple pieces of allowable duration corresponding to the multiple pieces of abnormal torque one to one; and after the allowable duration is reached, the vehicle is controlled to cut off power output. According to the control method, whether accidental acceleration of the vehicle is caused bya failure of the control system of the vehicle or not can be accurately determined, when accidental acceleration of the vehicle is caused by the failure of the control system of the vehicle, power output of the vehicle can be |
