The invention discloses an automobile automatic speed-limiting control system and a control method. The automobile automatic speed-limiting control system comprises a control unit and a signal collecting unit. The control unit comprises a controller, an ABS braking device and a control valve arranged on an automobile oil supply pipeline for controlling the flow of gasoline. The signal collecting unit comprises a speed sensor used for collecting a driving speed of an automobile, a speed limit acquiring device used for collecting a speed limit value of a current driving road section and a satellite positioning device used for collecting a current driving direction of the automobile and a road condition where the automobile is located. The controller judges whether the current automobile is overspeeded or not based on signals received from the speed sensor and the speed limit acquiring device. Based on the judging signals and the information acquired from the satellite positioning device, the opening degree of the control valve and the condition of whether to activate the ABS braking device or not are confirmed. According to the automobile automatic speed-limiting control system, the effects of user-friendliness, high practicality and high safety coefficient are achieved. The invention further provides a control method which has the safe, care-free and intelligentized effect.
