Intelligent linkage control system and method for rear windscreen wiper

Abstract

The invention provides an intelligent linkage control system for a rear windscreen wiper. The intelligent linkage control system comprises a signal collecting module, a control module and an execution module. The signal collecting module is used for collecting vehicle operation state information and working state signals of a front windscreen wiper and the rear windscreen wiper; an enabling condition and a closing condition are preset in the control module, the control module monitors the signals from the signal collecting module, compares the monitored signals with the enabling condition or the closing condition and sends out a control command according to the compared result; and the execution module is used for receiving the control command of the control module and automatically starting or stopping the rear windscreen wiper under driving of the control command. The invention further provides an intelligent linkage control system for the rear windscreen wiper. According to the intelligent linkage control system and method for the rear windscreen wiper, under the premise that the existing mechanical cost is not increased, the rear windscreen wiper is automatically started when needed, the visibility during rain and snow weather is improved, and the problems caused by long-term disuse of the rear windscreen wiper is solved.

Description

Technical field [0001] The invention relates to the technical field of wipers for automobiles, in particular to an improved intelligent linkage control system and method for rear wipers. Background technique [0002] At present, most existing sports utility vehicles (Sports Utility Vehicle, SUV for short) are equipped with a rear wiper system outside the rear window of the car. The basic principle of the intelligent control of the existing rear wiper system is the reverse intelligent start, that is, when the front wiper is working normally in low or high gear and the transmission gear is in reverse, the rear wiper will automatically start working; when When the transmission changes from reverse to other gears or the front wiper stops working, the rear wiper automatically stops working. The application scenario designed by this kind of intelligent control principle is to ensure that the driver has a good view of the rearview mirror in the car when the driver reverses in rain. [0...

AI Technical Summary

Problems solved by technology

[0004] First of all, if the rear wiper is not used for a long time, the rubber strip of the rear wiper will be in one direction for a long time to bear the pressure of the scraping wall, which will accelerate the aging of the rear wiper strip, and occasionally there will be jitter, abnormal noise, leakage Scratch and other failure modes

[0005] Secondly, if the rear wiper is not used for a long time, the lubrication at the kinematic joints of the internal mechanism of the rear wiper will fail, resulting in the internal jamming of the rear wiper motor, and when it is used occasionally, the rear wiper will not work and the motor will burn out. other failure modes

[0006] Finally, due to the aerodynamic characteristics of SUV models, there will be vortex at the rear. In rainy and snowy weather, rain, snow and dirt are easy to remain on the rear window, which leads to poor visibility of the middle rearview mirror and affects driving in rainy and snowy weather. vehicle safety
