The invention discloses a vacuum brake boosting system control method and a device applied to a vehicle. The vacuum brake boosting system control method and the device are used for solving the problem that safe and effective control is difficult to execute when a vacuum brake boosting system breaks down. According to the scheme, the method comprises the steps that a pressure signal of a vacuum brake boosting system of the vehicle and a brake signal of a brake pedal of the vehicle are obtained; according to the pressure signal and the brake signal, whether the vacuum brake boosting system breaks down or not is determined; if the vacuum brake boosting system breaks down, operation parameters of the vacuum brake boosting system are obtained, and the operation parameters comprise the vacuum degree of the vacuum brake boosting system and/or the opening and closing frequency of a vacuum pump; determining the fault type of the vacuum brake booster system according to the operating parameters; and executing a control strategy matched with the fault type on the vacuum brake booster system. According to the scheme provided by the embodiment of the invention, the fault type can be accurately recognized, the matched control strategy is executed for the generated fault, and the control effectiveness and safety are effectively improved.
