System for detecting windshield wiper noise and related methods

Abstract

A system for detecting noise generated by a windshield wiper on a vehicle including a cabin is provided. The system includes a detector for detecting noise generated by the windshield wiper. A processor is provided for generating a signal based on the noise detected by the detector. A controller may also receive the signal and regulate the operation of the windshield wiper, including by adaptive control based on a vehicle operator's desired setting of a speed of the wiper in an intermittent mode of operation. The signal may also be used to notify a service provider of the need for servicing the windshield wiper. Related methods are also disclosed.

Description

technical field [0001] This document relates generally to the field of motor vehicle equipment, more specifically to a system for detecting windscreen wiper noise and a related method. Background technique [0002] The windshield wipers may sound squeaky or "chatter" due to the "slip-stick" interaction between the wiper blades and the windshield. Flutter is affected by surface friction and the amount of water lubrication, as well as the condition and angle of the wiper blades, and is often the cause of complaints from vehicle operators. Typically, the operator will turn off the wipers or reduce their frequency to reduce chatter, but if this manual intervention is related to the quality or condition of the wiper blades, manual intervention won't really fix the underlying problem. Because chatter can be an intermittent phenomenon, vehicle operators often forget to raise the issue with their service provider during later repairs, only to be reminded of the problem when it recu...

Flutter is affected by surface friction and the amount of water lubrication, as well as the condition and angle of the wiper blades, and is often the cause of complaints from vehicle operators

Usually the operator will turn off the wipers or reduce their frequency to reduce chatter, but if this manual intervention is related to the quality or condition of the wiper blades, manual intervention will not really solve the underlying problem

Because chatter can be an intermittent phenomenon, vehicle operators often forget to raise the issue with their service provider during later repairs, only to be reminded of the problem when it recurs in the future, which can lead to Can't pay attention to this question
