System for cleaning a glass surface of a vehicle
A system for cleaning at least one glazed surface ( 21 ) comprises at least two devices ( 100 to 111 ) for projecting a cleaning product onto an associated glazed surface. The projection devices each include an electronic control module ( 120 ) configured to drive the operation of the corresponding projection device depending on control instructions, and the cleaning system includes a powerline bus common to the at least two projection devices ( 100 to 111 ), which are linked electrically to the powerline bus ( 11 ) independently of one another and in successive areas ( 90, 92 ) of said powerline bus.
1. A system for cleaning at least one glazed surface of a vehicle, comprising:
at least two projection devices for projecting a cleaning product onto an associated glazed surface,
wherein the projection devices each include an electronic control module configured to drive the operation of the at least two projection devices depending on control instructions; and
a powerline bus common to the at least two projection devices, which are linked electrically to the powerline bus independently of one another and in successive areas of said powerline bus.
2. The cleaning system according to claim 1 , wherein at least one of the projection devices is linked electrically to the powerline bus by way of an electrical connection element arranged on said bus.
3. The cleaning system according to claim 2 , wherein each of the projection devices comprises an electrical connection terminal configured to be linked to one of the electrical connection elements arranged on the powerline bus, and to the electronic control module.
4. The cleaning system according to claim 3 , wherein the electrical connection terminal comprises two electric power supply pins.
5. The cleaning system according to claim 4 , further comprising pairs of electrical wires in which each wire respectively links one pin of one of the connection terminals and one of the electrical connection elements.
6. The cleaning system according to claim 1 , wherein the electronic control module is configured to analyse all of the control instructions flowing through the powerline bus and to recover therefrom the control instruction(s) corresponding to its projection device.
7. The cleaning system according to claim 6 , wherein each of the projection devices comprises a solenoid valve and a sprinkler, said solenoid valve being driven by the electronic control module.
8. A system for cleaning at least one glazed surface of a vehicle, comprising:
