Abstract

This invention relates to an automated system for wiping of windshields of automobiles and the like and in particular to an automated wiping system with means for variation of mode and/or intensity of whiping, based on rainfall. The system is also integrated with manual option to change the mode of variable wiping. The invention further provides for an automated wiper systen with combination of options such as of intermittent operation with dwell-time variation between two wiping cycles of the wiper motor or continuous operation with speed control depending on the rainfall intensity and frequency. The automated wiper system can be adapted to be fitted into any variety of vehicles and is free from adverse effects of extraneous and environmental factors such as sound, impurities in the rainwater, presence of foreign bodies in the rainwater, dirt on the windshield, smog, etc. The automated system for wiping of windshields of automobiles and the like comprise: a rain sensor assembly comprising of rain water measuring device and/or a low rainfall detector; a detector selection control circuit operatively connected to said sensor assembly and adapted to generate signals based on output of said rain water measuring device and/or low rainfall detector to selectively actuate or deactive a wiper motor driving the wipers on said screen.
