The invention discloses a control method and device for a vehicle brake vacuum booster system, and the method comprises the steps: recording pedal brake data of a brake pedal of a vehicle under each pedal brake working condition and operation state data of a vacuum pump under each pedal brake working condition when a vehicle vacuum pressure sensor does not have a clamping stagnation fault; according to the recording result, the corresponding relation between the pedal braking data under each pedal braking working condition and the running state data of the vacuum pump is determined; and after the vehicle vacuum pressure sensor has the clamping stagnation fault, the operation state of the vacuum pump is controlled based on the corresponding relation. According to the control method and device of the vehicle brake vacuum boosting system, the corresponding operation states of the vacuum pump of the brake pedal under the different pedal brake working conditions are accurately recorded before the clamping stagnation fault occurs, the vacuum pump is reasonably controlled after the clamping stagnation fault occurs, necessary brake vacuum boosting can be provided, and the brake efficiency is improved. And the intelligent process of the vehicle braking vacuum boosting system is promoted.
