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.

    本发明涉及一种液压制动压力产生模块故障预测报警系统,包括:油箱、接通油箱的液压泵、连接至液压泵的电机、设置在液压泵出油口处的限压阀、用于储存油液的蓄能器、用于检测系统压力的蓄能器压力检测装置、用于检测限压阀压力保压值的限压阀压力检测装置和控制器,通过对系统压力建立时间、电机性能参数、限压阀的压力保压性能的参数特征,建立数据特征模型,根据正常的工作数据参数计算偏移量,并根据偏移量判断故障等级并输出报警信号,实现对液压制动系统压力产生模块的故障预测,提高系统可靠性。
