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 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.
1. 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, characterized 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.
2. The device as claimed in claim 1 , characterized in that the means for determining the wear of said blade consist in a controller of the vehicle connected to the on-board diagnostic input of the vehicle.
3. The device as claimed in claim 1 , characterized in that the means for determining the wear of said blade are integrated into said unit and are connected to the means for communicating electronically.
4. The device as claimed in claim 1 , characterized in that the means for determining the wear of the blade comprise means for generating the wear signal depending on the number of wiping cycles of the windshield-wiper blade.
5. The device as claimed in claim 1 , characterized in that the means for determining the wear of the blade comprise means for deducing or estimating a coefficient of friction between the one or more windshield-wiper blades and the surface of the windshield and means for generating a wear signal depending on said coefficient of friction and on the number of wiping cycles of the one or more windshield-wiper blades.
6. The device as claimed in claim 1 , characterized in that the means for communicating electronically consist in a Bluetooth transmitter that generates a communication according to the Bluetooth protocol with the electronic apparatus.
7. The device as claimed in claim 1 , characterized in that the means for communicating electronically consist in a transmitter that generates a communication according to the IEEE 802.11p protocol with the electronic apparatus.
8. The device as claimed in claim 1 , characterized in that the means for communicating electronically consist in a GSM and/or GPRS transmitter that generates a telephonic communication with a remote server.
9. The device as claimed in claim 1 , characterized in that the portable electronic apparatus consists in a smartphone or in a tablet computer or the like.
10. The device as claimed in claim 1 , characterized in that the message transmitted to said electronic apparatus contains a hyperlink.
