The invention relates to a device for remotely giving warning as to the state of wear of at least one blade of a windshield-wiper system of a vehicle comprising means for determining the wear of said blade and means for flagging said wear; said device is noteworthy in that it comprises at least one unit comprising a module called the removable diagnostic connector able to interact with a diagnostic service connector forming an on-board diagnostic input of the vehicle in order to establish a link with said diagnostic connector via the OBD protocol and means for communicating electronically that are coupled to the diagnostic connector and that are able to transmit, to a portable electronic apparatus, via a wireless link, a message indicating the wear of said blade when the means for determining the wear of the blade generate a signal referred to as a wear signal.

Device for remote warning about the state of wear of at least one wiper blade of a windscreen-wiping system

The invention relates to a method for determining the wiping use 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, the wiper blade carrier () being movable between a position of use, called a service position, and a maintenance position, said method being characterised in that it successively comprises: a step a) of acquiring at least one data element representing the presence of the wiper blade () in the maintenance position; a step b) of determining the replacement of the wiper blade with a new wiper blade; and a step (c) of estimating the wiping use of the new wiper blade.
