Automatic maintenance of front and/or rear windshield visibility

Abstract:

An apparatus comprising an interface and a processing circuit. The interface may be configured to receive (a) a video signal based on a targeted view in a vehicle and (b) one or more status signals from one or more sensors of the vehicle. The processing circuit may be configured to (A) analyze the video signal received from the interface and (B) detect a type of obstruction of a window of the vehicle visible in the video signal in response to (i) a classification of information in the video signal and (ii) one or more of the status signals. The processing circuit may (a) determine a confidence level for the type of obstruction, (b) activate one or more corrective measures when the confidence level is above a pre-defined threshold and (c) adjust the confidence level based on a response of the obstruction to the corrective measures.
