The invention belongs to the technical field of vehicles, and particularly relates to a vehicle-mounted rainfall detection device. The device comprises a rainfall detection module, a distance detection module, a rain level detection module and a speed detection module, wherein the rainfall detection module, the rain level detection module, the distance detection module and the speed detection module are electrically connected with the receiving end of a control module respectively; and the output end of the control module is electrically connected with a vehicle gear motor and a vehicle wiper motor. Thresholds are preset in the rainfall detection module and the distance detection module, the receiving unit of the control module obtains current rainfall and vehicle speed information, and the current rainfall and vehicle speed information are compared with a rainfall warning value and a collision distance value which are preset according to the preset value comparison unit, so that a comparison result is obtained, and a CPU generates a control instruction. And the gear motor and the wiper motor are controlled to drain and brake the vehicle, so that the safety of the vehicle running in rainy days is improved.
本发明属于车辆技术领域,尤其涉及一种车载雨量检测装置,包括雨量检测模块和距离检测模块,雨位检测模块和速度检测模块:所述雨量检测模块和雨位检测模块及距离检测模块和速度检测模块分别电连接控制模块的接收端,所述控制模块的输出端分别电连接车辆减速电机和车辆雨刮电机;本发明通过在雨量检测模块和距离检测模块预先设定阈值,通过控制模块的接收单元获取当前雨量和车速信息与根据预设值比对单元预先设置的雨量警戒值和碰撞距离值进行运算比对,得出比对结果CPU生成控制指令,控制减速电机和雨刮电机对车辆进行排水和制动,提高车辆在雨天行驶的安全性。
