The invention discloses an automobile rainwater drainage system with a fault monitoring function. The automobile rainwater drainage system comprises a rainfall measurement subsystem, a rainwater drainage subsystem, a data processing subsystem, a fault processing subsystem and an automobile posture sensing subsystem. The vehicle posture sensing subsystem is used for sensing the posture of a vehicle body, and if the posture of the vehicle body is within a selected vehicle posture range, the real-time flow of a drainage pipe of the rainwater drainage subsystem is started to be monitored; the data processing subsystem is used for comparing the real-time flow with the designed flow of the drainage pipe under the same rainfall and judging the through-flow efficiency deviation degree of the drainage pipe relative to a factory leaving state; if the through-flow efficiency deviation degree of a certain drainage pipe exceeds an allowable threshold value, it is judged that the drainage pipe breaks down, and the fault processing subsystem is triggered. According to the automobile rainwater drainage system with the fault monitoring function, on the basis of automatic monitoring of the efficiency of the automobile rainwater drainage mechanism, the automation technology of drainage fault diagnosis, prompt and fault removal of the automobile rainwater drainage system is achieved.

    本发明公开了一种具有故障监测功能的汽车雨水排水系统,其包括雨量测量子系统、雨水排水子系统、数据处理子系统、故障处理子系统及车姿传感子系统;所述车姿传感子系统,感测车身姿态,如在选定的车姿范围内,则开启监测雨水排水子系统的排水管的实时流量;所述数据处理子系统,将实时流量与相同雨量下该排水管的设计流量比较,判断该排水管相对于出厂状态的通流效能偏离度;如某条排水管的通流效能偏离度超过允许阈值,就判定该条排水管故障,触发故障处理子系统。本发明的一种具有故障监测功能的汽车雨水排水系统,基于汽车雨水排水机构效能的自动监测,实现了汽车雨水排水系统的排水故障诊断、提示与故障排除的自动化技术。
