The invention relates to a fault prediction and alarm system for a hydraulic brake pressure generation module. Comprising an oil tank, a hydraulic pump communicated with the oil tank, a motor connected to the hydraulic pump, a pressure limiting valve arranged at an oil outlet of the hydraulic pump, an energy accumulator used for storing oil, an energy accumulator pressure detection device used for detecting system pressure, a pressure limiting valve pressure detection device used for detecting a pressure maintaining value of the pressure limiting valve and a controller. A data characteristic model is established according to parameter characteristics of system pressure establishing time, motor performance parameters and pressure maintaining performance of a pressure limiting valve, offset is calculated according to normal working data parameters, the fault level is judged according to the offset, an alarm signal is output, and fault prediction of a pressure generation module of the hydraulic braking system is achieved. The system reliability is improved.
