Abstract

An intelligent windscreen wiper features that a rainfall sensor is installed to the front top of car to determine the value of rainfall and the motor of wind screen wiper is controlled by a single-chip microprocessor to work at optimal rotation speed. Its advantages are high reliability and anti-interference powr and high P / C ratio.

Description

technical field [0001] The invention relates to an intelligent wiper. Background technique [0002] When the car is running in rainy and snowy days, the front windshield glass will be blurred. In order to ensure that the driver has a good line of sight, a wiper and a washing device are installed on the car. The traditional car wiper is usually controlled by a manual switch to control the speed of the wiper motor or the intermittent working time of the wiper, which increases the driver's operating frequency. Contents of the invention [0003] The present invention provides an intelligent wiper for the above problems, which can automatically adjust the speed of the wiper motor in time according to the change of rainfall, so as to achieve better control of the wiper; the driver does not need to frequently operate the manual switch of the wiper to maintain a good line of sight . [0004] The technical solution provided by the present invention is: an intelligent wiper, inclu...
