Windscreen wiper control system capable of realizing automatic speed regulation

Abstract

The invention relates to a windscreen wiper control system capable of realizing automatic speed regulation. The windscreen wiper control system comprises an audio collecting device, a windscreen wiperdevice and a control device, wherein the audio collecting device is used for identifying and collecting sound waves which are generated when rainwater drops to hit the automobile glass, and transmitting the sound wave signals to the control device; the windscreen wiper device comprises a windscreen wiper and a drive motor which is connected with the windscreen wiper; the control device comprisesa single chip microcomputer and a memory, wherein the memory is used for storing the sound waves which are generated when rainwater of different amount drops to hit the automobile glass; and the control device is connected with the audio collecting device and the windscreen wiper motor through a signal line and is used for controlling the speed regulation of the drive motor according to the soundwave signal results sensed by the audio collecting device. According to the windscreen wiper control system disclosed by the invention, the audio collecting device is used for sensing and measuring the amount of rainfall, and transmitting the sensed signals to the control device; the sensed signals are compared with the sound waves which are generated by the hitting of drop rainwater against the automobile glass for different amount of rainfall and are stored in the control device; the wiping speed of the windscreen wiper is controlled through the control device; and automatic speed regulationis realized.

Description

technical field [0001] The invention relates to the field of wipers, in particular to an automatic speed-regulating wiper control system. Background technique [0002] The wiper is a device used to wipe off the raindrops and dust attached to the windshield of the vehicle to improve the visibility of the driver and increase driving safety. Cars almost everywhere have windshield wipers because they are required by law. [0003] Because the amount of rain is different, the wiping speed of the wiper can be adjusted; however, the wiper in the prior art is manually adjusted, so the operation is cumbersome and affects driving. Although some wipers have achieved intelligent control or stepless speed regulation, it is difficult to apply them on a large scale due to their insensitive sensors or high cost, especially in terms of automatic speed regulation. Therefore be badly in need of a kind of wiper control system that can realize intelligent control automatic speed regulation. C...
