Title: METHOD FOR MONITORING THE EVOLUTION OF THE STATE OF WEAR OF A WIPER BLADE
Abstract:
The invention relates to a method (100) for monitoring the evolution of the state of wear of a wiper blade pertaining to a wiper system used to wipe a window pane of a motor vehicle, with a view to replacing said wiper blade once it exceeds a determined wear threshold, said method being characterised in that it successively comprises: a step a) of determining the replacement of the wiper blade with a new wiper blade; a step b) of estimating or measuring the state of wear of the new wiper blade at an instant t0; a step c) of monitoring the evolution over time of the state of wear of the new wiper blade from the instant t0; and a step d) of detecting when the state of wear of the new wiper blade reaches or exceeds said threshold.
