Accelerometer-based vehicle wiper blade monitoring

Abstract

Method and apparatus are disclosed for accelerometer-based windshield wiper monitoring. A vehicle includes an accelerometer affixed to a vehicle window, a windshield wiper to actuate across the vehicle window, and a processor. The processor is configured to determine an acoustic profile corresponding to the windshield wiper based on structure-borne audio data received from the accelerometer, determine whether a bandlimited decibel level of the acoustic profile exceeds a threshold, and responsively provide an alert via a vehicle display.

Dependencies are inferred from the claim text.
