METHOD FOR DE-ICING A VEHICLE WINDOW

摘要

Method for washing a window of a motor vehicle, using a device comprising:
at least one tank containing a de-icing fluid,a tube system connecting the at least one tank to openings through which the fluid is sprayed onto the window,a supply pump designed to circulate the fluid in the tube system until it is ejected via the aforesaid openings, andat least one wiper blade suitable for moving over the window through the action of a drive motor,

characterized in that it comprises:
a) a division of the angular sector swept by said at least one blade into elementary sectors, andb) over at least one elementary sector, a modulation of the exit pressure from the supply pump between a “nominal” pressure and a non-zero pressure that is less than this nominal pressure.

1. A method for washing a window of a motor vehicle, said vehicle being equipped with a device comprising:
at least one tank containing a de-icing fluid; a tube system connecting the at least one tank to openings through which the fluid is sprayed onto the windscreen; a supply pump designed to circulate the fluid in the tube system until it is ejected via the aforesaid openings; and at least one wiper blade suitable for moving over the window between a low point and a high point through the action of a rotary-drive motor, the method comprising: a) a division of the angular sector swept by said at least one blade into elementary sectors, and b) over at least one of said elementary sectors, a modulation of the exit pressure from the supply pump between a “nominal” pressure and a non-zero reduced pressure that is less than this nominal pressure.
